Fit Gift: Sport Jelly Bellies Stocking Stuffer

FitSugar — Tue, 19 Dec 2006 10:30:00 -0800

We told you about the Sport Bean Jelly Belly when they first came out. Candy that keeps you energized while you work out is definitely something to celebrate! The Sport Beans are fortified with electrolytes and vitamins not found in the regular Jelly Belly.

Well the UC David Sport Medicine Program just studied the beans and found that they are just as effective as popular sports drinks and gels for maintaining blood sugar levels in athletes as well as improving their performance.

If they are good enough for a tri-athlete, they are definitely good enough for me. Why not put them in your loved ones stockings so they won't poop out in when they work out. They are a nice alternative to all the candy we usually stuff in stockings.

Glycemic Index vs. Glycemic Load

FitSugar — Fri, 08 May 2009 12:00:00 -0700

Just when you started to get a handle on the glycemic index (GI) of foods, there's another value to grasp - glycemic load (GL). The GI ranks specific carbohydrates from zero to 100, based on the rate in which they affect your blood sugar levels. A GI of 1 to 55 is low, 56 to 69 is medium, and 70 to 100 is high - these high-ranking foods should be limited.

Glycemic load measures the blood-sugar-raising power per serving of food. Here's the lowdown on the equations used to figure the load. First you multiply the GI of a food by the amount of grams of carbohydrate in a specific serving, and then that number is divided by 100. A glycemic load of 10 or less is low, 11 to 19 is medium, 20 or more is high. If you add up the glycemic load amounts for your entire day, a total GL amount of 80 or less is considered low. Your daily GL shouldn't exceed 120.

Both measurements are useful. Glycemic load helps you select appropriate portion sizes, while glycemic index helps you differentiate between good and bad carbohydrate choices. The lower each number, the less it affects blood sugar levels.

Looking at some food's values may help you understand the two better. So read more.

Food	GI	GL
1 medium apple	38	6
1 small banana	47	8
10 baby carrots	35	2
1 medium baked potato with skin	76	23
1 medium orange	42	5
1 medium pear	38	4
1 cup white rice	64	23
1 cup brown rice	55	18
1 cup regular pasta	44	18
1 cup whole wheat pasta	37	14
1 cup skim milk	32	4
1 oz. cashews	22	2
1 oz. peanuts	14	1
1 oz. jelly beans	78	22
2 tsp sugar	68	7
1 cup lentils	29	5
1 cup kidney beans	28	7
1 cup barley	25	11

A New Jelly in the Belly

FitSugar — Fri, 10 Nov 2006 11:30:00 -0800

Jelly Belly knows how to make a damn good bean. It never ceases to amaze me the things they come up with. Last year my nephews got Harry Potter themed jelly beans from Jelly Belly and the flavors like vomit, boogers and grass nearly killed me.

Now, Jelly Belly has moved away from the puke flavor of things and onto the sporty side. To find out what the sportiest member of the Jelly Belly family is, read more

Sport Beans (how great is the name, by the way?) are the latest in Jelly Belly's accomplishments. The beans are formulated with carbohydrates to fuel your body during intense exercise, and a balanced supply of electrolytes (sodium and potassium) vital for maintaining fluid balance, Thiamin (vitamin B1), Riboflavin (Vitamin B2), and Niacin (Vitamin B3) to help burn carbohydrates and fat, as well as Vitamin C to protect muscles and cells against oxidative damage. Could the sport beans be the first nutritionally dense candy?

The beans come in your typical "sport" flavors: Lemon Lime, Orange, Fruit Punch, and Berry Blue. (And why these flavors are always considered sporty, I'll never know.) According to their comparison chart (below), one ounce packs more nutrients than sport drinks. An Assorted Flavor 8-Pack is $7.92. Buy them here.

Complex carbohydrates

Simple carbohydrates

Starchy foods

HEALTH GUIDE REFERENCE FROM A.D.A.M

Definition

Carbohydrates are one of the main dietary components. This category of foods includes sugars, starches, and fiber.

Alternative Names

Starches; Simple sugars; Sugars; Complex carbohydrates; Diet - carbohydrates; Simple carbohydrates

Function

The primary function of carbohydrates is to provide energy for the body, especially the brain and the nervous system. Your liver breaks down carbohydrates into glucose (blood sugar), which is used for energy by the body.

Food Sources

Carbohydrates are classified as simple or complex. The classification depends on the chemical structure of the particular food source and reflects how quickly the sugar is digested and absorbed. Simple carbohydrates have one (single) or two (double) sugars while complex carbohydrates have three or more.

Examples of single sugars from foods include fructose (found in fruits) and galactose (found in milk products). Double sugars include lactose (found in dairy), maltose (found in certain vegetables and in beer), and sucrose (table sugar). Honey is also a double sugar, but unlike table sugar, contains a small amount of vitamins and minerals. (NOTE: Honey should not be given to children younger than 1 year old.)

Complex carbohydrates, often referred to as "starchy" foods, include:

Whole grain breads and cereals
Starchy vegetables
Legumes

Simple carbohydrates that contain vitamins and minerals occur naturally in:

Fruits
Milk and milk products
Vegetables

Simple carbohydrates are also found in processed and refined sugars such as:

Candy
Table sugar
Syrups (not including natural syrups such as maple)
Regular (non-diet) carbonated beverages, such as soda

Refined sugars provide calories, but lack vitamins, minerals, and fiber. Such simple sugars are often called "empty calories" and can lead to weight gain. Also, many refined foods, such as white flour, sugar, and polished rice, lack B vitamins and other important nutrients unless they are marked "enriched." It is healthiest to obtain carbohydrates, vitamins, and other nutrients in as natural a form as possible -- for example, from fruit instead of table sugar.

Side Effects

Excessive carbohydrates can cause an increase in the total caloric intake, causing obesity.
Deficient carbohydrates can cause a lack of calories (malnutrition), or excessive intake of fats to make up the calories.

Recommendations

For most people, between 40% and 60% of total calories should come from carbohydrates, preferably from complex carbohydrates (starches) and naturally occurring sugars. Complex carbohydrates provide calories, vitamins, minerals, and fiber.

Foods that are high in processed, refined simple sugars provide calories, but they have few nutritional benefits. It is wise to limit such sugars.

To increase complex carbohydrates and healthy nutrients:

Eat more fruits and vegetables.
Eat more whole grains, rice, breads, and cereals.
Eat more legumes (beans, lentils, and dried peas).

Here are recommended serving sizes for foods high in carbohydrates:

Vegetables: 1 cup of raw vegetables, or 1/2 cup cooked vegetables, or 3/4 cup of vegetable juice
Fruits: 1 medium size fruit (such as 1 medium apple or 1 medium orange), 1/2 cup of a canned or chopped fruit, or 3/4 cup of fruit juice
Breads and cereals: 1 slice of bread; 1 ounce or 2/3 cup of ready-to-eat cereal; 1/2 cup of cooked rice, pasta, or cereal; 1/2 cup of cooked dry beans, lentils, or dried peas
Dairy: 1 cup of skim or lowfat milk

For information about how many servings are recommended see the food guide pyramid.

Here is a sample 2,000 Calorie menu of which 50-60% of the total calories are from carbohydrates.

Breakfast
- 1 cup of raspberries
- 1 1/2 cups of unsweetened cereal, with 1/2 sliced banana
- 1 cup of skim milk

- 1/2 cup of shredded lettuce
- 1/2 cup of diced tomatoes
- 1/2 cup of green peppers
- 1 tablespoon of salad dressing
- 1 cup of skim milk
- 2 fresh, medium-sized peaches
Dinner
- 4 ounces of broiled salmon with 3 tablespoons of lemon juice, sprinkled with paprika
- 1 cup of pasta

What's the Deal With Electrolytes?

FitSugar — Fri, 17 Oct 2008 10:00:00 -0700

I know Jennifer Aniston loves her Smartwater, and I do too. That's because it's enhanced with electrolytes, a scientific term for salts. If you look on the bottle, you'll see ingredients such as sodium chloride, potassium, and magnesium, which are basically mineral salts. Your cells need these minerals in order to pass electrical impulses to other cells for normal bodily functions. Your kidneys work hard to keep the electrolyte concentrations in your blood consistent, but when you exercise intensely and sweat, you also lose electrolytes. If you don't replace these essential minerals, your performance declines, and you can eventually suffer serious health issues.

If you're exercising for long periods of time or sweating excessively from a workout, it's a good idea to take advantage of electrolyte-enhanced products. Sport drinks like Gatorade contain these necessary electrolytes, and they also contain sugar for quick energy and flavor. If you don't want to carry around a heavy, fake-flavored sport drink while exercising, then Luna Sport Moons, Jelly Belly Sport Beans, or Gu are great alternatives. If you want to avoid the sugar altogether, then go for Smartwater or Function Water.

Fit's Tip: Refueling on lost electrolytes isn't necessary for a regular 30-minute cardio workout, but hydration is. So be sure to drink water often. If you're training for a marathon or doing a three-hour cardio-kick-boxing workshop, then opt for sport drinks with electrolytes, since they'll give you both the minerals and fluids you need.

Treatment

Psoriasis that develops on the hands or feet is often very difficult to treat. However, an advanced clinical trial showed that a medication called efalizumab (Raptiva) effectively cleared or nearly cleared moderate-to-severe symptoms in adults after 12 weeks.

Several studies have shown that most people with severe psoriasis who are treated with infliximab (Remicade) have significant improvement in symptoms by week 10. The findings were presented at the 2007 annual meeting of the American Academy of Dermatology.

Continuing etanercept (Enbrel) after 12 weeks improves disease severity without an increase in infections or side effects, according to a study published in the Archives of Dermatology.

Disease classification

The National Psoriasis Foundation has proposed a new way to classify psoriasis. Instead of being grouped as mild, moderate, or severe, the group suggests a new two-tiered system that classifies patients as needing either local or body-wide (systemic) treatment.

Coexisting conditions

Studies from Newfoundland and Germany have revealed increased cases of diabetes, obesity, arthritis, and cancer in patients with psoriasis. Previous research has found an increased risk of heart disease in psoriasis patients. Research is underway to determine if there are genetic links between psoriasis and these conditions.

Severe psoriasis has been linked to a significant increase in a patient's risk of death. A study of more than 713,000 patients showed that severe psoriasis increased mortality by 50%. Such patients should receive comprehensive health examinations to reduce the risk, the authors recommended. Study participants were considered to have severe psoriasis if they required systemic treatment.

Smoking and psoriasis

Introduction

Psoriasis is a chronic skin disorder marked by periodic flare-ups of sharply defined red patches, covered by a silvery, flaky surface. The main disease activity leading to psoriasis occurs in the epidermis, the top five layers of the skin.

The process starts in the basal (bottom) layer of the epidermis, where keratinocytes are made. Keratinocytes are immature skin cells that produce keratin, a tough protein that helps form hair, nails, and skin. In normal cell growth, keratinocytes grow and move from the bottom layer to the skin's surface and shed unnoticed. This process takes about a month.

In persons with psoriasis, the keratinocytes multiply very rapidly and travel from the basal layer to the surface in about 4 days. The skin cannot shed these cells quickly enough, so they build up, leading to thick, dry patches, or plaques. Silvery, flaky areas of dead skin build up on the surface of the plaques before being shed. The underlying skin layer (dermis), which contains the nerves and blood and lymphatic vessels, becomes red and swollen.

Types of Psoriasis

Various forms of psoriasis exist. Some can occur alone or at the same time as other types, or one may follow another. The most common type is called plaque psoriasis, also known as psoriasis vulgaris.

Plaque psoriasis leads to skin patches that start off in small areas, about one-eighth of an inch wide. They usually appear in the same areas on opposite sides of the body.

The patches slowly grow larger and develop thick, dry plaque. If the plaque is scratched or scraped, bleeding spots the sizes of pinheads appear underneath. This is known as the Auspitz sign.

Some patches may become ring shaped (annular), with a clear center and scaly raised borders that may appear wavy and snake-like.

As the disease progresses, eventually separate patches may join together to form larger areas. In some cases, the patches can become very large and cover wide areas of the back or chest. This is known as geographic plaques because the skin lesions resemble maps.

Plaque psoriasis may persist for long periods. More often it flares up periodically, triggered by certain factors such as cold weather, infection, or stress.

Patches most often occur on the:

Elbows
Knees
Lower back

The may also be seen on the:

Upper pelvic bone area
Bottom of the feet
Calves and thighs
Genital areas
Palms of hands

Psoriasis of the scalp affects about 50% of patients. In some cases, the psoriasis may cover the scalp with thick plaques that extend down from the hairline to the forehead.

Psoriasis patches rarely affects the face in adulthood. In children, psoriasis is most likely to start in the scalp and spread to other parts of the body. Unlike in adults, it also may occur on the face and ears.

Psoriatic arthritis (PsA) is an inflammatory condition characterized by stiff, tender, and inflamed joints. Estimates on its prevalence among those with psoriasis range from 2 - 42%. AIDS patients and those with severe psoriasis are at higher risk for developing PsA.

About 80% of PsA patients have psoriasis in the nails. Arthritic and skin flare-ups tend to occur at the same time. It is not clear whether psoriatic arthritis is a unique disease or a genuine variation of psoriasis, although evidence suggests they are both caused by the same immune system problem.

Although patients with psoriatic arthritis tend to have mild skin symptoms, the disease affects the entire body. PsA, therefore, is more serious than the more common plaque psoriasis. Infrequently, the course of PsA has been associated with a syndrome known by the acronym SAPHO, which stands for:

Synovitis (inflammation in the joints)
Acne
Pustule eruptions
Hyperostosis (abnormal bony growths)
Osteolysis (bone destruction)

Some experts group PsA into five forms. The forms differ according to the location and severity of the affected joint:

Symmetric PsA: Symptoms occur in the same location on both sides of the body. It usually affects multiple joints. In about half of the cases, the condition will get worse. The condition is very similar to, but less disabling than, rheumatoid arthritis. The psoriasis itself is often severe.
Asymmetric PsA: This form involves periodic joint pain and redness, usually in only one to three joints, which can be the knee, hip, ankle, wrist, or one or more fingers. The pain does not occur in the same location on both sides of the body.
Distal interphalangeal predominant (DIP): DIP involves the joints of the fingers and toes closest to the nail. It occurs in about 5% of PsA cases.
PsA in the spine: Inflammation in the spinal column (spondylitis) is the primary symptom in about 5% of PsA cases. Such patients may have stiffness and burning sensations in the neck, lower back, sacroiliac, or spinal vertebrae. The spine can be involved in many patients with PsA, even though stiffness and burning sensations in these areas are not the primary symptoms. When it affects the spine, psoriatic arthritis most frequently targets the sacrum (the lowest part of the spine). Movement is difficult.
Arthritis mutilans: This is a severe, deforming, and progressive form of arthritis. It affects less than 5% of PsA cases. It mainly affects the small joints of the hands and feet, but it can also be found in the neck and lower back. Arthritic and skin flares and remissions tend to coincide.

People who start to smoke after developing psoriasis may delay the onset of psoriatic arthritis, according to research presented at the 2007 annual meeting of the Society for Investigational Dermatology. Researchers found that in nonsmokers, the time between psoriasis diagnosis and psoriatic arthritis development was 13 years, compared to 23 among those who started smoking after the onset of psoriasis. Study participants who smoked before developing psoriasis had psoriatic arthritis occur in about 8 years. However, smoking causes serious health problems and should not be considered as a way to delay this type of psoriasis.


Psoriasis Form	Description of Skin Patches	Comments
Guttate Psoriasis	The patches are teardrop-shaped and appear suddenly, usually over the trunk and often on the arms, legs, or scalp. They often disappear without treatment.	Guttate psoriasis can occur as the initial outbreak of psoriasis, often in children and young adults 1 - 3 weeks after a viral or bacterial (usually streptococcal) respiratory or throat infection. A family history of psoriasis and stressful life events are also highly linked with the start of guttate psoriasis. Guttate psoriasis can also develop in patients who have already had other forms of psoriasis, most often in people treated with widely-applied topical (rub-on) products containing corticosteroids.
Inverse Psoriasis	Patches usually appear as smooth inflamed patches without a scaly surface. They occur in the folds of the skin, such as under the armpits or breast, or in the groin.	Inverse psoriasis may be especially difficult to treat.
Seborrheic Psoriasis	Patches appear as red scaly areas on the scalp, behind the ears, above the shoulder blades, in the armpits or groin, or in the center of the face.	Seborrheic psoriasis may be especially difficult to treat.
Nail Psoriasis	Tiny white pits are scattered in groups across the nail. Toenails and sometimes fingernails may have yellowish spots. Long ridges may also develop across and down the nail. The nail bed often separates from the skin of the finger and collections of dead skin can build up underneath the nail.	Over half of patients with psoriasis have abnormal changes in their nails, which may appear before other skin symptoms. In some cases, nail psoriasis is the only symptom.
Generalized Erythrodermic Psoriasis (also called psoriatic exfoliative erythroderma)	This is a rare and severe form of psoriasis, in which the skin surface becomes scaly and red. The disease covers all or nearly all of the body.	About 20% of such cases evolve from psoriasis itself. The condition may also be triggered by certain psoriasis treatments, and other medications such as corticosteroids or synthetic antimalarial drugs.
Pustular Psoriasis	Patches become pus-filled and blister-like. The blisters eventually turn brown and form a scaly crust or peel off. Pustules usually appear on the hands and feet. When they form on the palms and soles, the condition is called palmar-plantar pustulosis.	Pustular psoriasis may erupt as the first occurrence of psoriasis, or it may evolve from plaque psoriasis. A number of conditions may trigger pustular psoriasis, including infection, pregnancy, certain drugs, and metal allergies. It can also accompany other forms of psoriasis and be very severe.

Causes

The precise causes of psoriasis are unknown. It is generally believed to be due to damage in factors in the immune system, enzymes, and other materials that control skin cell division. This prompts an abnormal immune response, which causes rapid production of immature skin cells and inflammation.

The Normal Immune System Response. The inflammatory process is the result of the body's immune response, which fights infection and heals wounds and injuries:

When an injury or an infection occurs, white blood cells are mobilized to rid the body of any foreign invaders, such as bacteria or viruses.
The masses of blood cells that gather at the injured or infected site produce factors to repair wounds, clot the blood, and fight infections.
In the process, the surrounding area becomes inflamed (red and swollen), and some healthy tissue is injured.

The Infection Fighters. The primary infection-fighting units are two types of white blood cells: lymphocytes and leukocytes.

Lymphocytes include two subtypes known as T cells and B cells. Both types of cells are designed to recognize foreign substances (antigens) and launch an offensive or defensive action against them:

B cells produce antibodies, which are designed to attack the antigens. Antibodies can either ride along with a B cell or travel on their own.
T cells have special receptors attached to their surface that recognize the specific antigen.

T cells are further categorized as killer T cells or helper T cells (TH cells).

Killer T cells directly attack antigens found on bacteria or other cells.
Helper T stimulate B cells and other white cells to attack the antigen.

The actions of the helper T cells are of special interest. Researchers have found high numbers of helper T cells in psoriatic plaques. Helper T cells normally stimulate B cells to produce antibodies. In psoriasis, however, they appear to direct the B cells to produce autoantibodies ("self" antibodies), which attack skin cells. In psoriatic arthritis, cells in the joints also come under attack.

Helper T cells also release or stimulate the production of powerful immune factors called cytokines. In small amounts, cytokines are very important for healing. If overproduced, however, they can cause serious damage, including inflammation and injury during the psoriasis disease process. In psoriasis, researchers are particularly interested in cytokines known as GRO-alpha, tumor necrosis factor, and certain interleukins.

Cytokines attract large numbers of other large white blood cells known as neutrophils. Neutrophils stimulate the production of arachidonic acid, producing two key players in the inflammatory process:

Leukotrienes: These chemicals attract even more white blood cells to the inflamed area.
Prostaglandins: These chemicals widen blood vessels and increase blood flow.

A combination of genes is involved with increasing a person's susceptibility to the conditions leading to psoriasis.

HLA Molecules. The processes leading to all autoimmune diseases involve the human leukocyte antigen (HLA) system. HLA molecules pick off parts of antigens and present them on the surface of a cell so that the various infection-fighting factors in the immune system can recognize and destroy them. Most immune disorders, including psoriatic arthritis, are due to problems with this system. For example, psoriasis patients with an HLA genetic factor called HLA-CW6 tend to develop psoriasis at an earlier than average age. However, only 10% of people who have this gene develop psoriasis. Other genetic and environmental factors are required to actually trigger the disease.

PSORs. Researchers have now identified four key genes (named PSOR 1 - 4) that are involved with psoriasis. Of particular interest are the genes located in regions on specific chromosomes that are linked to HLA and tumor necrosis factor, another immune factor strongly associated with psoriasis.

Weather, stress, injury, infection, and medications, while not direct causes, are often important in triggering the disease process leading to the start and worsening of psoriasis.

Weather. Cold, dry weather is a common trigger of psoriasis flare-ups. Hot, damp, sunny weather helps relieve the problem in most patients. However, some people have photosensitive psoriasis, which actually improves in winter and worsens in summer when skin is exposed to sunlight.

Stress and Strong Emotions. Stress, unexpressed anger, and emotional disorders, including depression and anxiety, are strongly associated with psoriasis flare-ups. In one study, nearly 40% of patients remembered a specific stressful event that occurred within a month of a psoriasis flare. Other research has suggested that stress can trigger specific immune factors associated with psoriasis flares.

Infection. Infections caused by viruses or bacteria can trigger some cases of psoriasis. For example:

Streptococcal infections in the upper respiratory tract, such as tonsillitis, sinusitis, and strep throat, are known to trigger guttate psoriasis in children and young adults. The infections may make ordinary plaque psoriasis worse.
Human immunodeficiency virus (HIV) is also associated with psoriasis.
An uncommon form of human papillomaviruses (HPV) called EV-HPV has been associated with psoriasis. Although EV-HPV is probably not a direct cause, it may play a role in the continuation of psoriasis. This HPV form is not the virus associated with cervical cancer and genital warts.

Skin Injuries and the Köbner Response. The Köbner response is a delayed response to skin injuries, in which psoriasis develops later on at the site of the injury. In some cases, even mild abrasions can cause an eruption, which may be a factor in the frequency of psoriasis on the elbows or knees. It should be noted that psoriasis can develop in areas with no history of skin injury.

Medications. Drugs that can trigger the onset of the disease, worsen symptoms, or cause a flare-up include:

Angiotensin-converting enzyme (ACE) inhibitors, drugs used to treat high blood pressure and heart problems
Beta-blockers, drugs used to treat high blood pressure and heart problems
Chloroquine, a medicine used to treat malaria
Lithium for bipolar disorder treatment
Indomethacin, a nonsteroidal anti-inflammatory drug (NSAIDs) -- Note: Other NSAIDs, such as meclofenamate, may actually improve the condition.
Progesterone, used in female hormone therapies

Flare-ups of severe psoriasis may occur in persons who stop taking steroids taken by mouth, or who discontinue use of very strong steroid ointments that cover wide skin areas. The flare-ups may be of various psoriatic forms, including guttate, pustular, and erythrodermic psoriasis. Because these drugs are also used to treat psoriasis, this rebound effect is of particular concern.

Medications that cause rashes, a side effect of many drugs, can trigger psoriasis as part of the Köbner response.

Risk Factors

Between 5.8 and 7.5 million Americans have psoriasis. Risk factors for psoriasis include:

Age under 20. About 40% develop the condition before age 20. Psoriasis (most often plaque psoriasis) can even occur in infants.
Climate. Some studies have found that the disorder develops earlier and more frequently in colder climates. For example, psoriasis occurs more frequently in African-Americans and in Caucasians who live in colder climates than in people of any ethnicity who live in Africa.
Ethnicity. Psoriasis is uncommon in Native Americans of either North or South American descent.
Family history of the disease. About 35% of those with psoriasis have one or more family members with the disorder.
Male gender. Some studies have indicated that more men than women have psoriasis.

Diagnosis

A microscopic examination of tissue taken from the affected skin patch is needed to make a definitive diagnosis of psoriasis and to distinguish it from other skin disorders. Usually in psoriasis, the examination will show a large number of dry skin cells, but without many signs of inflammation or infection. Specific changes in the nails are often strong signs of psoriasis.

Several conditions produce symptoms that resemble those of psoriasis. For example:

Seborrheic psoriasis is hard to distinguish from seborrheic dermatitis (dandruff is one form of this condition). Seborrheic dermatitis patches are usually greasy, yellowish, and crusty. Nail involvement may also help differentiate psoriasis.
Generalized erythrodermic psoriasis may be confused with drug allergic reactions, atopic eczema, and symptoms of lymphomas.
Fungal infections, other skin conditions, or circulation problems may also cause nail changes typical of psoriasis.

Symptoms of psoriatic arthritis may also resemble the following:

Rheumatoid arthritis (RA). As in rheumatoid arthritis, psoriatic arthritis can cause pain or tenderness in one or more joints, and morning stiffness is common. People with psoriatic arthritis, however, lack a particular antibody, called rheumatoid factor, which is found in the blood of many people with rheumatoid arthritis.
Systemic lupus erythematosus (SLE). Symptoms of SLE may include both a psoriasis-like rash and arthritis, which could make the diagnosis difficult.
Reiter's disease. Reiter's disease is a syndrome that includes arthritis and inflammation in the eyes and urinary tract. It also causes skin lesions that are very similar to psoriasis, which are usually raised patches on the lips, penis, palms, and soles.
Gout. Gout causes pain, often in the fingers and toes.

Some evidence now indicates that inflammation in psoriatic arthritis may be distinguished from other arthritic conditions by its occurrence in sites where muscle tissue inserts into the bone (called enthesitis) rather than in the joint, which is a common site in other inflammatory arthritic conditions.

Severity of psoriasis itself ranges from one or two flaky inflamed patches to widespread pustular psoriasis that, in rare cases, can be life threatening. To help determine the best treatment for a patient, doctors usually classify the disease as mild to severe. The classification depends on how much of the skin is affected:

Mild psoriasis affects less than 3% of the body surface. Most cases of psoriasis are limited to less than 2% of the skin.
Moderate psoriasis covers 3 - 10% of the skin.
If more than 10% of the body is affected, the disease is considered severe.

The palm of the hand equals 1% of the body. The severity of the disease is also measured by its effect on a person’s quality of life.

However, the National Psoriasis Foundation has proposed a new classification method. The group suggests a new two-tiered system that classifies patients as needing either local or body-wide (systemic) treatment.

While disease severity impacts treatment success, some forms of psoriasis can be very resistant to treatment even though they are not categorized as severe. They include:

Any psoriasis on the palms and soles (hand and foot psoriasis)
Inverse psoriasis (which occurs in the folds of the skin)
Scalp psoriasis
Psoriatic arthritis

Many creams, ointments, lotions, and pills are available for the treatment of psoriasis. Many patients require only over-the-counter treatment, or even none at all during relapses.

About a third of patients with psoriasis, however, do not respond to over-the-counter remedies and lifestyle changes, and require aggressive treatments. In some cases, such treatments need to be lifelong.

In general, there are three treatment options for patients with psoriasis.

Topical medications such as lotions, ointments, creams, and shampoos
Body-wide (systemic) medications, which involve pills or injections that affect the whole body, not just the skin
Phototherapy, which uses light to treat psoriasis lesions

Individual requirements vary widely, and treatment selection must be carefully discussed with the doctor.

Giving treatment in a particular order is a strategy for providing both quick relief of symptoms and long-term maintenance. It involves three main steps:

The quick fix, to clear the psoriatic lesions during an acute outbreak (for example, a high-strength topical steroid in mild-to-moderate psoriasis, or an oral immunosuppressant in more severe cases)
The transitional phase, intended to gradually introduce the maintenance drug
Ongoing maintenance therapy

Choices for transitional or maintenance treatments depend on the severity of the condition. Some examples are described in the following sections.

In severe chronic cases, a doctor may recommend rotational therapy. This approach alternates treatments. The goal is to prevent severe side effects or build-up of resistance from long-term use of a single medicine. An example of a rotational schedule may be the following:

The patient gets phototherapy for about 2 years.
The patient then takes one or two powerful body-wide drugs for 1 - 2 years and stops.
Phototherapy starts again, and the cycle repeats.

Some doctors use the Koo-Menter Psoriasis Instrument (KMPI) to decide which patients should receive a pill or an injection. The KMPI’s questions include:

Does psoriasis cover at least 5% of the patient’s body?
Is the patient disabled by psoriasis?
Does psoriasis affect the patient’s quality of life?

If the answer to these questions is "yes," three additional questions are considered:

Is light therapy inappropriate for the patient?
Is the patient’s psoriasis resistant to light therapy?
Does the patient have psoriatic arthritis?

If the answer to these questions is “yes,” a doctor may decide to prescribe a pill or injected drugs.

Doctors increasingly use combinations of pills, creams, ointments, and phototherapy instead of single medications. Combinations of oral treatments are particularly useful, since the doses of each drug can be reduced. This lowers the risk of severe side effects. Thousands of combinations are possible, and the patient and doctor should discuss the best treatment for individual needs.

Topical Medications

Topical medications are those applied only to the surface of the body. They come in the following forms:

Creams
Foams
Gels
Lotions
Occlusive tapes
Ointments
Shampoos
Solutions
Sprays

In general, topical treatments are the first line for mild-to-moderate psoriasis, but they may also be used, alone or in combination, with more powerful treatments for moderate-to-severe cases. Topical medicines rarely produce complete clearance, however.

Corticosteroid topical treatments are the mainstay of psoriasis treatments in the United States. They work for most patients. Such treatments:

Decrease inflammation
Block cell production
Relieve itching

Corticosteroids are available in a wide range of strengths, and are generally given as follows:

Less potent drugs are used for mild-to-moderate psoriasis.
Stronger drugs are reserved for more severe disease.

In the past, topical steroids have been used twice a day. Studies are reporting, however, that certain drugs may work just as well if taken once a day. Most studies have evaluated high-potency steroids, but one study suggested that those of medium strength, such as triamcinolone (Aureocort, Tri-Adcortyl), may be equally beneficial as a once-daily treatment. However, corticosteroids used alone clear psoriasis in only 4 - 36% of patients.

Combination therapy. Combinations with other drugs are often needed. For example, an effective, topical regimen uses the following combination for maintenance therapy:

A high-potency steroid (such as halobetasol) on the weekend
A vitamin D3 topical medication called calcipotriene, twice daily on weekdays

In one study, more than 75% of patients with mild-to-moderate psoriasis remained in remission for at least 6 months with this regimen.

Side Effects. The more powerful the corticosteroid, the more effective it is. But it also has a higher risk for severe side effects. Side effects may include:

Burning
Irritation
Dryness
Acne
Thinning of the skin; skin may become shiny, fragile, and easily cut
Dilated (widened) blood vessels
Loss of skin color

Loss of Effectiveness. In most cases, the patients become tolerant to the effects of the drugs, and the drugs no longer work as they should. Some experts recommend using intermittent therapy (also called weekend or pulse therapy). This type of treatment involves applying a high-potency topical medication for 3 full days each week.

Note: This list is not all inclusive.
Low potency (some are available over the counter)	Desonide (Tridesilon, DesOwen) Flumethasone pivalate (Locorten) Fluocinolone acetonide (Synalar, Derma-Smoothe) Hydrocortisone (Hytone, Penecort, Synacort, Cort-Dome, Nutracort, Westcort) Triamcinolone acetonide (Aristocort)
Low to medium potency	Alclometasone dipropionate (Aclovate) Hydrocortisone (Locoid, Pandel) Hydrocortisone valerate (Westcort) Prednicarbate (Dermatop)
Medium to upper-mid potency	Clocortolone pivalate (Cloderm) Fluticasone propionate (Cutivate) Mometasone furoate (Elocon) Triamcinolone acetonide (Aureocort, Tri-Adcortyl, Kenalog)
High potency	Betamethasone (Diprosone) Amcinonide (Cyclocort) Desoximetasone (Topicort) Diflorasone diacetate (Florone, Maxiflor) Fluocinonide (Lidex) Halcinonide (Halog)
Very high potency	Halobetasol propionate (Ultravate) Betamethasone (Diprolene, Luxiq) Clobetasol propionate (Temovate, Olux) Diflorasone diacetate (Florone, Maxiflor, Psorcon)

Coal tar preparations have been used to treat psoriasis for about 100 years, although their use has declined with the introduction of topical vitamin D3-related medicines. Crude coal tar stops the action of enzymes that contribute to psoriasis, and helps prevent new cell production. Tar is often used in combination with other drugs and with ultraviolet B (UVB) phototherapy.

Side Effects. Preparations have the following drawbacks:

Stains on clothing
Skin irritation
Sun sensitivity and increased risk of sunburn for up to 24 hours after use

Anthralin (Dritho-Scalp, Drithocreme, Micanol) is related to a medication called chrysarobin, in use since the early 1900s. Anthralin slows skin cell reproduction and can produce remissions that last for months. It is recommended only for chronic or inactive psoriasis, not for acute or inflamed eruptions. Persons with kidney problems should use anthralin with caution.

As with tar, its use has also declined with introduction of the topical vitamin D-related medicines, but newer formulations, such as Micanol, have made its use more tolerable. Micanol (Psoriatec) is an anthralin formulated in microcapsules, which dissolve and allow the drug to be delivered directly to the target skin areas. It is particularly useful for scalp psoriasis, and it is less likely to stain.

Side Effects. Anthralin may cause the following side effects:

Skin irritation and burning
Staining of clothes, hair, fabrics, plastics, and other household products

Patients should not use anthralin on their faces. Fair skinned people should generally avoid it. Triethanolamine (CuraStain) is a chemical that can neutralize anthralin and help reduce irritation from short-contact anthralin treatment. It should be applied 1 or 2 minutes before washing off the anthralin. It is then reapplied after drying the skin.

Washing stained items with hypochlorite (Clorox) detergents can help remove stains. Many people use disposable gloves while applying the treatment to avoid staining hands.

Application. Apply anthralin only to the psoriasis plaques. Rub the cream in well, and wipe off any excess. Wash off only with lukewarm water, not soap. Using hot water will trigger the staining action. A technique called short-contact anthralin therapy (SCAT), also called minute therapy, is useful for local areas of psoriasis. In such cases, anthralin is applied for only 10 minutes to an hour.

A topical form of vitamin D3, calcipotriene (Dovonex) is proving to be both safe and effective. It is now available in a foam preparation, which makes compliance even easier. Several other topical vitamin D3 related drugs showing promise include maxacalcitol (Oxarol), tacalcitol, and calcitriol (Silkis).

Calcipotriene appears to:

Block skin cell reproduction
Enhance the maturity of keratinocytes (the impaired skin cells in psoriasis)
Acts as an anti-inflammatory

It works just as well as moderate topical corticosteroids, short-term anthralin, and coal tar in improving mild-to-moderate plaque psoriasis. Unlike steroids, patients do not develop thinning of the skin or tolerance to the drug.

Using the drug in combination with other topical and systemic treatments may improve effectiveness. Calcipotriene doesn't work as well as the highest potency corticosteroids, but products or regimens that combine both medications are proving to be more effective than either one alone. Taclonex, an ointment containing both calcipotriol and betamethasone, was approved by the U.S. Food and Drug Administration (FDA) in January 2006 for the treatment of adults with psoriasis. Studies show the combination works better than either drug alone.

Combining vitamin D ointments with systemic medicines, notably methotrexate, acitretin, or cyclosporine, increases effectiveness and allows lower doses or either medication, thereby reducing side effects.

Studies also report success in some patients who use vitamin D ointments in combination with phototherapy treatment.

Side Effects. Calcipotriene may cause the following side effects:

A possible lowering of vitamin D levels, which may affect bone growth in some children
A possible increase in blood calcium levels (seen in some people who apply calcipotriene to large areas)
Skin irritation in about 20% of patients, particularly on the face and in skin folds

Calcipotriene appears to cause greater skin irritation than potent corticosteroids. Diluting the drug with petrolatum or applying topical corticosteroids to sensitive areas may prevent this problem.

Retinoids are related to vitamin A. They are used for various skin disorders. Tazarotene (Tazorac) is the first topical retinoid found to be effective for mild-to-moderate psoriasis. It is available in cream or gel form.

Unlike steroids, patients do not develop thinning of the skin or tolerance to the drug. Only a very small amount is needed on each lesion. It can be used on the scalp and nails, but it is not recommended for the genital areas or around the eyes. The gel should be used on only 20% of the body at anytime; the cream on up to 35%. (Note: The palm of the hand is about 1% of the body surface.)

Combining topical retinoids with other psoriasis treatments, such as with topical steroids, works better than using the drug by itself.

Side Effects. Tazarotene may cause dryness and irritation of healthy skin. Applying zinc oxide and moisturizer around the treated area can protect the healthy skin.

At levels high enough to be effective for psoriasis, tazarotene can cause severe skin irritation on treated areas. This medicine, then, is usually used in combination with other treatments, therefore allowing a lower dose. Mixing the drug in equal amounts with petroleum jelly (Vaseline) initially and then gradually increasing the amount of tazarotene may help the skin areas become less sensitive. It should be noted that the skin can become very red while it is actually improving.

Vitamin A derivatives (drugs related to vitamin A) have been associated with birth defects and should not be used by women who are pregnant, who wish to conceive, or who are nursing.

Salicylic acid applied to the skin helps remove scaly plaque and enhance the actions of other medications. It should not be used to cover wide areas of the body, since it can cause nausea and ringing in the ears. Combinations with high potency steroids, such as mometasone furoate (Combisor), clobetasol propionate, and betamethasone, are proving to be very helpful. Only Combisor is available in the United States.

Watertight (occlusive) tapes or wrappings may help heal psoriasis. Occlusive tapes are particularly useful for psoriatic cuts on the palms and soles. In such cases, the tape should be applied across the cuts until they heal.

Occlusive tapes retain sweat, which helps restore moisture to the outer skin layer and prevent scaling. They also protect against abrasion and irritation.

High-Potency Corticosteroid Tapes. Applying a corticosteroid beneath an occlusive tape, or using a tape that already has a potent corticosteroid (Cordran Tape) such as flurandrenolide may be especially beneficial. Studies are showing that high-potency corticosteroid-containing tapes are more effective than using high-potency corticosteroid ointments alone.

However, the tapes are expensive and are associated with a high rate of skin irritation, increased secondary infections, and a greater chance of symptoms relapse after treatment is stopped. Infection risk may be reduced by changing tapes every 12 hours.

The use of corticosteroids under occlusive tapes on large areas of psoriasis also increases the risk for adrenal insufficiency, a sometimes dangerous condition that occurs because the body loses its ability to produce natural steroids. Children are especially vulnerable to this effect.

Other Medications with Occlusive Tapes or Wrappings. The tapes may be used in combination with other medications, such as fluorouracil. Occlusive wrappings are not usually used with tazarotene (Tazorac) and should never be used without a doctor's recommendation.

Numerous topical medications are under investigation. One such medication, tacrolimus (Protopic), is an immunosuppressant that is proving to be useful in allergic skin disorders and is being studied for psoriasis. Studies have been mixed on its benefits, although new delivery methods may make it more effective. It may prove to be safe for sensitive areas, such as the face. Pimecrolimus (Elidel), a similar medication, is also being studied.

Systemic Medications

Systemic treatment uses various medications that affect the whole body, not just the skin. Many systemic drugs used for psoriasis are also used for other severe diseases, including autoimmune diseases (especially rheumatoid arthritis) and cancer.

Systemic treatments for psoriasis may be taken by mouth or injection. The medicines can have significant side effects and are generally reserved for severe psoriasis.

At this time, the only systemic medications specifically approved for psoriasis are:

Cyclosporine
Methotrexate
Retinoids

As with all medications for psoriasis, the patient should use the lowest strength medication first. The primary treatment is called a first-line treatment, the next is known as a second-line treatment, and so on. Combinations of medications are often used.

Methotrexate (Rheumatrex) is a biologic drug that interferes with cell reproduction and has anti-inflammatory properties. It is a first line, or primary, systemic drug used to treat adults with severe psoriasis. The medicine is one of the few systemic drugs proven to help patients with psoriatic arthritis.

The drug is taken weekly, not daily. (Deadly reactions have been reported in people who mistakenly took it once a day.)

Side Effects. Common side effects of methotrexate include:

Anemia
Headache
Mild hair loss
Mouth sores
Nausea
Possible muscle aches
Rash
Vomiting

Many of these side effects are due to folic acid deficiency. Patients should ask their doctor if folic acid supplements (generally recommended at 1 - 5 mg daily) are necessary.

More serious side effects include:

Increased risk for infections, particularly shingles and pneumonia. Methotrexate suppresses the immune system. Patients with active infections should avoid this drug.
Infertility, miscarriage, and birth defects. If used during pregnancy, the drug can cause miscarriages or birth defects in the baby. It may harm fertility in men.
Kidney complications.
Liver damage. In one study, 25% of patients taking methotrexate for 5 years developed scarring of the liver. Those with existing liver problems should not take this medicine, if possible. Regular monitoring for liver toxicity, including blood tests and liver biopsies, is important in patients who take the drug.
Lung disease. This side effect can be sudden and severe, and occurs in up to 5% of people who take methotrexate. Risk factors include diabetes, existing lung inflammation, protein in urine, and use of rheumatoid arthritis drugs called DMARDs.
Lymphomas. A few cases have been reported, which are most likely related to the drug's immune-suppressing (lowering) effects. In most instances, the disease has gone into remission when the drug was stopped. Most studies have found no significant risk for cancers in patients taking methotrexate.
Osteoporosis. Low doses of methotrexate do not appear to have any significant effect on bone loss, but long-term studies are needed to confirm this.
Radiation recall: An uncommon side effect in patients who have previously been burned by radiation cancer treatments or sunburns. In such cases, a flare-up of symptoms occurs in the previously affected skin areas.
Severe anemia. Folic acid supplements can offset this effect.
Toxic effects on bone marrow. This can cause reduced blood cell production.

Despite its side effects, some experts view methotrexate as the best therapy for widespread plaque psoriasis. It may also be effective for some patients with other severe forms of the disease, including psoriatic arthritis, generalized erythrodermic, and pustular psoriasis.

Methotrexate appears to be effective in children, but more safety research is needed.

Drug Interactions. Many drugs interact with methotrexate, occasionally with harmful results. For example, the antibiotic trimethoprim-sulfamethoxazole increases the toxicity of methotrexate.

A serious, harmful reaction can occur if methotrexate is taken with common, nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, or naproxen. Other NSAIDs, namely ketoprofen, flurbiprofen, and piroxicam, appear to be safe when given with methotrexate and may be used in patients with psoriatic arthritis. Rheumatoid arthritis (RA) patients who take methotrexate often take NSAIDs as well, but methotrexate doses in psoriasis patients are usually much higher than those in RA.

People Who Should Avoid Methotrexate. Pregnant and nursing mothers should never take methotrexate because it increases the risk for severe, even fatal, birth defects and miscarriage. The drug should be discontinued several months before planning a pregnancy. It may also cause temporary impairment of fertility in men.

Persons with the following conditions should also avoid taking methotrexate:

Alcoholism
Anemia or other blood abnormalities
Immunosuppression
Kidney problems
Liver problems (including hepatitis)
Rheumatoid arthritis
Peptic ulcers

Patients at risk for liver complications include those with diabetes and obesity. Anyone with a history of hepatitis should have a liver biopsy before taking methotrexate.

Oral retinoids are vitamin A-related medications taken by mouth. This group of medicines is also a first-line treatment for adults with severe psoriasis. Oral retinoids used for psoriasis include acitretin (Soriatane) and isotretinoin (Accutane).

Acitretin is the retinoid of choice and may be dramatically effective for severe psoriasis, particularly pustular or erythrodermic variants. When used alone, it is much less effective against more common forms, such as plaque or guttate psoriasis. However, combinations with PUVA phototherapy can markedly improve the response even in these patients.

Accutane, more commonly used to treat acne, is far less potent than acitretin, but may still be effective against pustular psoriasis and also be effective with phototherapy.

Oral retinoids help control cell reproduction and have anti-inflammatory properties. They may even improve arthritis that accompanies psoriasis.

Combination therapy. Acitretin may work the best when combined with other treatments, usually topical drugs and especially phototherapy. Combination therapy allows lower doses of oral retinoids to be used, which diminishes many skin and mucous membrane side effects. Acitretin combined with phototherapy has some of the highest clearance rates of any treatment.

Side Effects. All retinoids have the same potentially serious toxicities as do high doses of vitamin A. Side effects include:

Bone and joint pain
Bruising
Depression and possible suicide risk (with isotretinoin)
Eye problems, including blurred vision, cataracts, conjunctivitis, and a sudden deterioration in night vision
Fatigue
Headache
Increased bone growth, particularly in the ankles, pelvic area, and knees
Increased triglyceride levels
Liver damage
Nail problems
Skin and mucous membrane problems, including dry nose, nosebleeds, dry eyes, chapped lips, thinning hair, dry or "sticky" feeling skin, and peeling of the palms and soles

In rare cases, retinoids, particularly isotretinoin, may cause a condition called benign intracranial hypertension (pseudotumor cerebri), which occurs in the brain. Symptoms include headache, nausea, vomiting, and blurred vision. Patients experiencing these symptoms should call a doctor immediately and stop taking the drug.

Oral retinoids should not be taken during pregnancy.

Despite these side effects, oral retinoids remain among the safest systemic therapies for psoriasis. A low-fat diet, aerobic exercise, and fish oil supplements may help reduce the side effects. Certain cholesterol-lowering drugs, including gemfibrozil (Lopid) or certain statins, such as atorvastatin (Lipitor), may help control triglyceride levels.

Maintenance doses should be as low as possible and should be taken every second or third day.

Taking retinoids during pregnancy significantly increases the risk for severe birth defects in the unborn child. Pregnant or nursing women or those planning to become pregnant should not use these drugs. Women of childbearing age who take retinoids should have regular pregnancy tests.

Doctors recommend that acitretin should not be given to any woman who may become pregnant within 3 years of taking it. Drinking alcohol changes acitretin to a retinoid that is stored in fat cells for 3 years. It may have the potential for causing birth defects during that time. It's important to note that cooking products and over-the-counter preparations, such as cough syrup, may contain alcohol and be inadvertently consumed.
Women who are pregnant or plan to become pregnant should not use isotretinoin. As of December 31, 2005, everyone who takes, prescribes, or dispenses the drug must enroll in a national registry called iPLEDGE.

Cyclosporine (Neoral, Sandimmune, SangCya) blocks certain immune factors and may be effective for all forms of psoriasis. It is also a first line, or primary, systemic drug used to treat adults with severe psoriasis. Neoral is the preparation used most often for psoriasis and clears psoriasis in many patients within 8 - 12 weeks.

Side Effects. Cyclosporine has significant side effects if used for a long time, notably kidney problems and non-melanoma skin cancers. It should be reserved for patients who do not respond to phototherapy or less potent systemic medications (for example, methotrexate or acitretin).

Common and temporary side effects include:

Fatigue
Gingivitis
Gout
Hair growth
Headaches
Joint pain
Tremor

More serious complications may include:

Kidney damage
High blood pressure (Some doctors advise treating high blood pressure with calcium channel blockers, since other standard blood pressure drugs may worsen psoriasis. Calcium channel blockers also help prevent kidney problems.)
High cholesterol and lipid levels
High levels of calcium and low levels of magnesium
Increased risk for infections
Liver problems
Lymphomas
Skin cancers (Patients who have taken cyclosporine after PUVA therapy have a higher incidence of squamous cell skin cancer. According to a 2003 study, the risk is six times that of the general population. The risks are highest with long use and previous use of PUVA, methotrexate, or other immunosuppressants.)

To reduce complications of cyclosporine, the dosage is decreased after improvement occurs. Maintenance therapy is usually limited to a year, although some experts believe that a microemulsion form of Neoral (Neoral-Neo) may be safe for up to 2 years. Patients should be monitored regularly for high blood pressure and signs of kidney or liver problems and skin cancers.

Patients Who Should not Use Cyclosporine. Because the drug suppresses the immune system, people with active infections or cancer should avoid it. Patients with uncontrolled high blood pressure and impaired kidney function should also not use this medication. Cyclosporine therapy for children with psoriasis has not been well studied.

Drug and Food Interactions. Cyclosporine interacts with numerous drugs -- both prescription and over-the-counter preparations -- and also grapefruit and grapefruit juice.

Biological response modifiers, sometimes called "biologics," belong to a new class of drugs that are considered the most exciting development in psoriasis treatment. Biologics are genetically engineered drugs that interfere with specific components of the autoimmune response. Because of their precise targets, these drugs do not damage the entire immune system the way that general immunosuppressants do.

Biologics are considered second- or third-line treatments, and may be used alone or sometimes in combination with first-line systemic drugs.

There are different types of biologics used to treat psoriasis:

T cell blockers block immune cells linked to inflammation.
Tumor necrosis factor (TNF) blockers target the chemical messenger TNF-alpha, which is released during the inflammatory response.

Types of T-cell blockers:

Alefacept (Amevive). This drug is approved for the treatment of moderate-to-severe plaque psoriasis. Studies suggest that the drug produces 50 - 75% improvement in symptoms. Alefacept is given in a doctor's office or clinic. Patients receive weekly injections for 12 weeks. Patients need weekly blood tests to make sure T cell levels do not drop too low. Side effects are generally mild and include sore throat, dizziness, and cough. There have been a few reports of serious infection and cancer.
Efalizumab (Raptiva). This drug is approved for the treatment of moderate-to-severe plaque psoriasis. Many patients experience 50 - 75% improvement in symptoms within 4 - 6 weeks of starting the drug. Patients give themselves shots of this drug for 12 weeks. Some clinical trials suggest that a longer course of treatment (24 weeks) may also be safe and effective for patients with chronic plaque psoriasis. Some patients have flare-ups of psoriatic lesions after stopping efalizumab. Very serious, but rare, side effects include hemolytic anemia and antibiotic-resistant infections.

Types of TNF blockers:

Etanercept (Enbrel) is approved for the treatment of psoriatic arthritis and moderate-to-severe plaque psoriasis. The drug is given either alone or in combination with methotrexate. Side effects include infections and lymphoma, a type of cancer. Patients inject themselves under the skin, once or twice a week for 12 weeks. However, a 2007 study published in the Archives of Dermatology found that continuing etanercept after 12 weeks lowers the severity of disease without increasing infections or side effects. Study participants randomly received 50 milligrams of the drug or a placebo biweekly up to 84 weeks. Strongest improvements were noted at 48 weeks among those who received the drug.
Infliximab (Remicade) is approved for the treatment of psoriatic arthritis. Patients receive three intravenous infusions during the first 6 weeks of treatment. After the initial treatment period, patients receive an infusion every 8 weeks. Therapy takes 2 hours and is given in a doctor’s office or clinic. Patients with a history of infection or heart failure should not take this drug. Several studies have shown that symptoms improve significiantly by week 10 in the majority of patients with severe psoriasis who are treated with infliximab.
Adalimumab (Humira) is being tested in clinical trials for treatment of psoriasis and psoriatic arthritis. Results from a Phase III (late-stage) study show that the drug works better than methotrexate in the treatment of moderate-to-severe psoriasis.
Efalizumab (Raptiva) appears to effectively clear or nearly clear moderate-to-severe hand and foot psoriasis after 12 weeks. This type of psoriasis is often very difficult to control and treat.

Interleukins (IL) being investigated as sources or targets of therapy include IL-4, IL-2, IL-8, IL-11, and IL-12. For example, in a 2003 study, 75% of patients with severe psoriasis who were treated with interleukin-4 (rhuIL-4) experienced improvement rates of more than 68%.

A study of 180 patients with moderate-to-severe plaque psoriasis has shown that an investigational medicine called ABT-874 greatly reduced symptoms in most patients. ABT-874 targets proteins that are responsible for psoriasis-related inflammation.

Leflunomide. Leflunomide (Arava) is a disease-modifying antirheumatic drug (DMARD), which blocks autoimmune antibodies and is a powerful anti-inflammatory medication. It is proving to be active against psoriatic arthritis. Reports of adverse effects are comparable to those with methotrexate. Common problems include nausea, diarrhea, hair loss, and rash. Potentially serious side effects include infections and liver injury.

Sulfasalazine. Sulfasalazine (Azulfidine) is sometimes used for psoriasis. In one major analysis, sulfasalazine and methotrexate were the only medications proven to help patients with psoriatic arthritis. Many people, however, stop taking the drug because of common side effects that include headaches, gastrointestinal complaints, and rash. Benefits, if any, should be apparent in 4 - 6 weeks.

Immunosuppressants. Some immunosuppressants being studied for psoriasis include tacrolimus (Prograf), pimecrolium, and sirolimus. In one study, for example, tacrolimus showed an 83% reduction in symptoms in patients with psoriasis who used the drug. Studies have been limited, however. Side effects of these medications are similar to those of cyclosporine. Pimecrolimus may specifically target the skin and so have fewer side effects. (Some are also being studied as topical treatments.)

Phototherapy

Phototherapy means to treat with light.

When sunlight penetrates the top layers of the skin, this ultraviolet radiation bombards the DNA inside skin cells and injures it. This can cause wrinkles, aging skin, and skin cancers. However, these same damaging effects can destroy the skin cells that form psoriasis patches.

Phototherapy for psoriasis can be given as ultraviolet A (UVA) light in combination with medications, or as variations of ultraviolet B (UVB) light with or without medications. Not everyone is a candidate. For example, it may not be appropriate for patients who should avoid sunlight or those with very severe psoriasis.

Ultraviolet A (UVA) is a main part of sunlight. UVA phototherapy uses a photosensitizing medication (usually psoralen) in combination with UVA radiation to be effective. A photosensitizing medication makes a person more sensitive to light. Treatment with psoralen and UVA is referred to as PUVA. This approach is very powerful and effective in more than 85% of patients who use it. However, it poses a higher risk for skin cancers than UVB.

PUVA treatments cause inflammation and redness in the skin to develop within 2 - 3 days after treatment. Such damage inhibits skin cell proliferation and reduces psoriasis plaque formation.

Forms of psoralen include methoxsalen, 8-methoxypsoralen (8-MOP), or bergapten (5-MOP). The effectiveness of the treatment is based on a chemical reaction in the skin between the psoralen and light, which creates redness and inflammation that prevents the psoriasis disease process.

People should avoid this treatment if they are taking drugs or have conditions that cause them to be light sensitive. They should also take protective measures before, during, and after each treatment.

Initial PUVA Treatment Phase. The initial phase typically follows these steps:

Psoralen is typically taken by mouth in the form of 8-methoxypsoralen (for example, Oxsoralen) 75 minutes to 2 hours before the treatment starts. Psoralen reaches the skin through the bloodstream, where it increases the skin's sensitivity to UVA radiation.
Topical preparations of psoralen are alternatives to pills. They can be "painted on" or applied to the affected areas by soaking or bathing in a psoralen solution. PUVA-bath therapy may be especially useful for persistent psoriasis on the palms and soles or for patients with liver disease or who get severe nausea from taking the pill form. UVA should be given within 15 minutes of using topical psoralen.
The patient enters and stands in a light box, a unit lined with ultraviolet lamps. The initial UVA exposure time is very short (seconds to several minutes), and then increases to 20 minutes or longer. The amount of time a person is exposed to UVA rays depends on the skin type, with the shortest times recommended for fair-skinned patients.
Treatments may be repeated two or three times a week. They should never be performed more frequently than once every other day, since the full effects of the treatments are not evident for 48 hours.

It takes an average of about 25 PUVA treatments for full effect, but during that period, treatment intensity may vary.

If there is no response after 10 treatments, the doctor may increase the UVA energy.
If there is still no response after 15 treatments, the psoralen dosage may be increased.
If a patient's skin does not improve at all or worsens after these changes, the treatment is temporarily stopped. PUVA may be causing a toxic response in such cases, and, often, the condition gradually improves over the following 2 weeks.
If the skin does not improve over the following 2 weeks, PUVA treatment has failed. If skin improves during this resting period, treatment resumes.

Maintenance Phase. Once the psoriasis has improved by about 95%, the patient may be put on a maintenance schedule. Often only one or two treatments a month are needed, but some people may need more frequent treatments. As maintenance continues and the interval between treatments lengthens, the patients may become more susceptible to tanning and sunburn. They should reduce exposure to natural sunlight during this time.

Success Rates. Nearly 90% of patients achieve marked improvement or clearing within 20 - 30 treatment sessions.

Combinations. Combining acitretin, calcipotriene, methotrexate, or tazarotene gel with PUVA may enhance effectiveness or increase response. In addition, combinations may allow for lower doses of radiation or medications to be used, minimizing side effects. Retinoids may also help protect against skin cancers, while methotrexate may increase the risk. In some cases, patients resistant to PUVA or UVB may respond when the phototherapies are combined.

Side Effects and Complications of PUVA.

The psoralen methoxsalen causes a general ill-feeling and nausea in 20% of patients. Dividing up the dose and taking it in 15-minute intervals with food, or taking ginger 20 minutes before taking the drug, may be helpful.
Skin reactions, including itching, sunburn, and blistering, are common. These can generally be avoided with careful administration of PUVA therapy and protective measures. Antihistamines, baths with special oatmeal preparations (Aveeno), and capsaicin ointment (Zostrix) may be helpful.
After treatment, white spots commonly develop where psoriasis plaques had been, particularly in people with naturally darker skin. If they are troublesome, tanning products may help darken them. Small, dark raised spots called PUVA lentigines may also develop in affected areas with long-term treatment
Prolonged standing may trigger fainting in people with certain heart or blood pressure problems.
People with liver disease should discuss using topical psoralens, since oral forms may have adverse effects on the liver.
UVA penetrates the skin more deeply than UVB, so there is a greater danger of deep skin damage, accelerated skin aging, and skin cancers. Anyone who needs to avoid sunlight should not get this treatment.
The procedure increases the risk for cataracts if eyes are not protected for up to 24 hours after treatment.

Special Warning on PUVA and Skin Cancers. It has been known for some time that PUVA can change DNA and cause genetic mutations. PUVA is known to increase the risk for squamous cell skin cancer and slightly increase the risk for basal cell skin cancer, both of which are nearly always curable. One study reported an increased risk of melanoma. The risk for skin cancers is higher in persons who have:

A family or personal history of skin cancer
Light skin and fair or red hair
Received radiation or x-ray treatments or taken immunosuppressant drugs
Received over 200 PUVA treatments

Discussions are under way about discontinuing PUVA for psoriasis. The arguments generally are as follows:

Opponents of PUVA argue that studies suggest a long-term risk for melanoma, starting about 15 years after treatment, particularly in people who receive more than 250 treatments. In one long-term study, only 9 out of 1,380 patients developed melanoma. However, 7 of these cases occurred in the last 5 years of the study, indicating that the danger persists and more patients in this study are likely to develop this serious skin cancer as time goes on.
Supporters of PUVA argue that it is not yet known if the people who developed melanoma experienced sunburn during the procedures or if they already had risk factors for skin cancers. If so, then properly given treatments could still be considered safe for patients without risk factors. They also argue that PUVA is still the most effective treatment for severe psoriasis, and the alternatives are usually very powerful and relatively new drugs that may have even more serious side effects. Furthermore, the addition of retinoids may protect against skin cancers while proving to be a very effective combination.

Side effects of UVA radiation can be severe. Protective measures are needed during, before, and after treatment. Patients should avoid prolonged exposure to the sun for 24 hours before the oral treatment starts.

Protective Measures During Treatment:

Patients should wear specially designed goggles to protect the eyes from UVA radiation.
Sensitive areas, such as genitals, abdominal skin, and breasts, should be covered until tanning occurs in the exposed areas, after about a third of the treatment period. Note that PUVA is associated with a high risk for genital skin cancers, so male genitals must be covered throughout the process.

The following safety features should be available in the PUVA chamber:

Lamps with protective shields
A viewing window for a health professional to check the patient periodically
A door that can be opened by the patient easily and with little pressure
A timer that terminates the session automatically
An accessible alarm device

Protective Measures After Treatment. The drugs used in PUVA increase susceptibility for a natural sunburn for hours after treatment. The patient should take the following precautions:

Patients should wear UVA absorbing wrap-around sunglasses that are designed to completely block out stray radiation. They should begin wearing them as soon as they take the drug, and for at least 12 hours after the treatment. This is important to prevent a PUVA reaction around the eyes that can cause cataracts. There is no need to wear these glasses after sundown.
For about 8 hours after taking the drug, patients must also avoid exposure to daylight, even if the day is cloudy or exposure occurs through windows.
Patients who must go out should wear heavy opaque clothing (clothes that do not let light through), including hats and gloves.
Patients should apply sunblock over all exposed areas, including the lips. The sunblock should have an SPF (sun protection factor) of more than 15 and include ingredients that block both UVB and UVA radiation.
No patient should spend a long time in sunlight for at least 2 days after the combined treatment.

Ultraviolet B is another main part of sunlight, and is the main cause of sunburn. It generally affects the outer skin layers. UVB radiation reduces the abnormally rapid skin cell growth that occurs with psoriasis.

Types of UVB therapy:

Broadband UVB
Narrowband UVB (NB-UVB)
Laser treatments

Broad spectrum or broad band UVB is radiation in the wavelength of 290 - 350 nanometers, and is the standard UVB phototherapy treatment in the United States. It is not as potent as the treatments that use narrow-band UVB or PUVA, and is not useful for chronic psoriasis.

Broadband UVB may be given with or without medications. When used without medication (known as selective ultraviolet phototherapy), UVB treatment generally is given as follows:

Treatment starts in the doctor's office or another medical setting. Once the disease has stabilized, the patient can obtain a prescription for equipment that can be used at home. Even at home, treatment must always be supervised.
In preparation, the patient fully undresses, although unaffected areas may be covered to avoid overexposure.
The initial session may last as little as a few seconds, depending on whether the patient has a lighter or darker skin, with the lightest skin exposed to the briefest session. The duration increases with each treatment until the skin clears or the patient experiences itching or irritation. It should be noted that the condition may worsen initially.
UVB therapy usually requires about 20 - 40 treatments (about three per week). Full results take about 3 weeks.

Use of Medication. UVB was commonly used with coal tar (the Goeckerman regimen) in past decades, and then with anthralin (the Ingram regimen). Other medications are being studied with some success, and may prove to be tolerated better.

The Goeckerman regimen requires daily treatments for up to 4 weeks. The coal tar or anthralin are applied once or twice each day and then washed off before the procedure. Studies indicate that a low-dose (1%) coal tar preparation is as effective as high dose (6%). Such regimens are unpleasant, but still useful for some patients with severe psoriasis, since they can achieve long-term remission (up to 6 - 12 months).

Some evidence suggests that using a simple emollient (such as Vaseline or mineral oil) that enhances UVB light penetration can be effective. This addition to the treatment increases the risk for sunburns, however, and patients must be careful to avoid sun exposure. Researchers are tring combinations of other topical and oral medications. For example, combining UVB with methotrexate, or retinoids such as a tazarotene gel or oral acitretin, is producing positive results. Combinations with any of these drugs, however, must be supervised carefully to avoid serious reactions.

Side Effects of UVB. The treatment can cause itching and redness. UVB radiation from sunlight is known to increase the risk for skin cancers. There is no strong evidence, however, that UVB treatments pose any risk for skin cancers except on male genitalia. This risk, however, can be significant (4.5%) at high doses.

Narrow band radiation may be safer than other approaches, and some experts now believe it should be the first option for patients with chronic plaque psoriasis.

NB-UVB is used without medications and is very strong. Whether it has any affect, however, on the disease process itself is unclear. The light wavelength is between 310 - 312 nanometers, which, theoretically, is the most beneficial part of sunlight.

Exposure times are shorter but of higher intensity than with broadband UVB. This therapy is probably less likely than PUVA to cause skin cancers.

Clearance of 75% typically occurs after 10 - 12 treatments. NB-UVB treatments performed three times a week achieve results that are equal to twice-weekly PUVA treatments. Weekly NB-UVB treatments are not effective. Studies so far are mixed on whether NB-UVB remission rates are equal to those of PUVA.

Patients prefer NB-UVB over other PUVA treatments because they do not have to wear protective eyewear, take medications, or experience unpleasant side effects, notably nausea. It is also safe for pregnant women and children.

Combinations with topical medications, such as tazarotene or psoralens, may help NB-UVB therapy work better.

Laser UVB Treatment. A recent variation of a device called an excimer laser (Xtrac) delivers a precise UVB wavelength of 308 nanometers. The laser is more effective than narrow-band UVB for localized psoriasis, since it allows very specific areas of skin to be targeted. (Note: The therapy is not suitable for the scalp.) Generally, 8 - 10 treatments given twice a week will clear psoriasis. Remission rates are similar to NB-UVB, but the excimer laser can clear the psoriasis faster and at lower doses. It also spares the healthy skin around it. Blistering is a common side effect. More comparison studies are needed to determine risk and benefits compared to NB-UVB, particularly any long-term risk for skin cancer.

Pulsed-Dye Lasers. Pulsed-dye lasers give off high-intensity yellow light, which destroys the tiny blood vessels that make up psoriatic plaques. This treatment has been used for years to remove birthmarks, such as port wine stains and unsightly blood vessels on the skin. Some studies have reported significant (but not complete) improvement, and remissions that have lasted up to 13 months. Treatment sessions last up to 30 minutes and can feel uncomfortable (similar to being repeatedly snapped with a rubber band). It typically takes up to six sessions to clear the target areas. Bruising is common, and there is a small risk for scarring.

Home tanning devices and tanning salons are not usually recommended, but they may be helpful for patients without access to a medical unit. In a 2003 study, many patients achieved a significant reduction in symptoms when taking acitretin and exposed to a UVB commercial tanning unit (specifically, a Wolff tanning bed).

However, UV outputs can vary widely among tanning beds and salons. Some units emit UVA radiation, which poses a higher risk for skin cancers. Adverse effects of tanning salons that use UVA or UVB radiation are the same as with any UV phototherapies, including a risk for skin cancer.

Managing Psoriasis

Although sunburn carries a risk for skin cancer and can make psoriasis worse, regular exposure to the sun helps clear psoriasis in people with mild-to-moderate conditions. People should cover non-affected areas with clothing or sunscreen and sun bath only until the skin starts to tan.

Vacations in sunny areas, such as Hawaii or the Caribbean, can offer relief. For those who can afford it, a prolonged stay of several weeks at the Dead Sea in Israel has proven to significantly improve or clear 88% of those with psoriasis who go there. The region offers a unique combination of intense but naturally filtered UVA radiation combined with minerals and salts from the sea.

Because of the association between negative emotions and psoriatic flare-ups, relaxation and anti-stress techniques may be helpful. A small 1999 study found that hypnosis aimed at reducing stress may relieve symptoms.

Another study found that some patients with psoriasis had a traumatic or stressful event coincide with the appearance of psoriasis. Talking to a psychiatrist about the issue resulted in significant symptom improvement in 62% of study patients who recalled such an event.

If skin becomes dry and itchy, the patient may try the following:

Soak in a warm bath for about 15 minutes.
Afterward, apply salicylic acid first, which removes scaly skin and may promote the penetration of both moisturizers and topical prescription medications.
Then, apply a thick moisturizer or emollient, such as Vaseline, Cetaphil cream, or Eucerin cream. Lotions are not good enough moisturizers.
Special gloves made of Gore-Tex (DermaPore) may be worn at night over a thick moisturizer cream. These gloves are protective but also allow moisture to escape.

Some experts suggest that many common moisturizers may actually increase water loss in psoriasis, but studies still have to confirm this. In the meantime, if moisturizers help relieve the condition, patients should use them.

Capsaicin (Zostrix) is an ointment prepared from the active ingredient in hot chili peppers. It is used to relieve arthritic pain and may help relieve psoriatic itching. Capsaicin should be handled using a glove and applied to affected areas three or four times daily. The patient will usually have a burning sensation when the drug is first applied, but this sensation lessens with use.

Folic Acid. Patients should be sure they get enough of the B vitamin folate (folic acid). Folate-rich foods include liver, asparagus, fruits, green leafy vegetables, dried beans and peas, orange juice, and yeast. Many types of bread and other commercial grain products now have added folic acid.

Omega-3 Fatty Acids. Omega-3 fatty acids, particularly those found in some fish oil, have anti-inflammatory properties that may benefit some patients with psoriasis and other autoimmune conditions.

Patients with persistent psoriasis may be tempted to try alternative or untested treatments, including herbs and other nontraditional therapies. Researchers at the Medical College of Georgia say green tea slowed the growth of skin cells in animal studies and may one day prove to be useful in treating psoriasis. More research is needed.

Several traditional remedies for psoriasis include various other herbal supplements, but to date no clinical studies have been reported on these substances. No one should use any unproven therapy without consulting a doctor to be sure such treatment is not harmful, and does not interfere with any standard medications they take.

Herbal remedies and dietary supplements are not regulated by the FDA. This means that manufacturers and distributors do not need FDA approval to sell their products. In addition, any substance that affects the body's chemistry can, like any drug, produce side effects that may be harmful. There have been many reported cases of serious and even deadly side effects from herbal products.

The following are special concerns for people taking natural remedies for psoriasis:

Zinc pyrithione is sometimes used, but its effectiveness is doubtful. A number of so-called natural psoriasis products (Skin-Cap, Blue Cap, Miralex) that contain this compound also contain prescription-strength corticosteroids. Such steroids have the same side effects as those in standard psoriasis agents. These products have been banned in the U.S. and Canada, but similar untested medications are available over the Internet.
Gotu Kola (Centella asiatica) is sometimes applied in a cream for psoriasis. The oral form of the herb has serious side effects, however, including increasing the risk for miscarriage in pregnant women.

Outlook

Psoriasis is lifelong and not curable. Although it is also marked by rapid cell growth, psoriasis is neither cancerous nor contagious.

In general, studies report the following features of its course:

The condition almost always relapses. In a few cases, large areas of plaque can persist for years.
Psoriasis nearly always goes into remission, however, often clearing on its own. In one study, 30% of patients reported untreated psoriasis going into remissions that lasted 1 - 54 years.
Psoriasis can improve during pregnancy, especially during the second and third months. Increased levels of estrogen may be responsible for this improvement. Relapse may occur after giving birth.

The emotional and social consequences of psoriasis should not be underestimated.

Many patients suffer severe humiliation and depression if plaques are visible. Some even withdraw from society and become isolated.
Some patients are forced to leave their jobs and go on disability if the condition becomes incapacitating.

Researchers have reported the following:

Surveys of patients with psoriasis report a negative mental and physical impact that is nearly equivalent to that of other major chronic conditions, including cancer, high blood pressure, diabetes, heart disease, and depression.
In one study, 75% of patients reported that psoriasis hurt their confidence.
Another study reported that 8% of people with psoriasis felt their life was not worth living.

Some patients, particularly men, use alcohol and smoking as self-medication to reduce the emotional consequences of psoriasis. In fact, studies have found that people with psoriasis have higher mortality rates, mostly from heavy drinking. Smoking has also been cited as a major risk, particularly for pustular psoriasis. Some experts believe that drinking and smoking may actually cause biological damage that contributes to psoriasis itself.

However, smoking may delay the onset of psoriatic arthritis in some patients, depending on when they started the habit. Psoriatic arthritis tends to occur about a decade after psoriasis develops. The review of 281 psoriasis patients showed that the condition appeared after about 13 years in nonsmokers, compared to 23 years in those who began smoking after the first onset of psoriasis. Psoriatic arthritis appeared after 8 years in people who smoked before developing psoriasis.

Folate Deficiency in Severe Psoriasis. Severe psoriasis can also cause folate deficiency. Folate is a B vitamin that is important for nerve function, preventing birth defects. It also prevents elevations of homocysteine, a factor that may play a critical role in heart disease.

Skin Cancers. In one study, patients with severe psoriasis (who receive medications that affect the whole body) were at higher than normal risk for developing cancers, primarily skin cancers and lymphomas. The risk was not any higher for patients with milder psoriasis. There is some indication, however, that patients with psoriasis have a higher risk for non-melanoma skin cancers regardless of treatments.

Heart Attacks. A study released in October 2006 shows an increased risk of heart attacks in people with psoriasis. The risk was highest in young patients with severe psoriasis.

Other Coexisting Conditions: Studies done in Newfoundland and Germany have also revealed increased cases of diabetes, obesity, arthritis, and cancer in patients with psoriasis. Research is underway to determine if there are genetic links between psoriasis and these conditions.

Increased Risk of Death. Severe psoriasis has been linked to a significant increase in a patient's risk of death. A study of more than 713,000 patients showed that severe psoriasis increased mortality by 50%. Study authors encourage patients to receive comprehensive health examinations to reduce the risk. Study participants were considered to have severe psoriasis if they required systemic treatment.

Impaired Temperature Regulation. Erythrodermic psoriasis, in which psoriasis covers the entire skin, can cause abnormalities in the body's ability to regulate temperature.

Zumbusch Psoriasis. A combination of erythrodermic and pustular psoriasis causes a serious condition called Zumbusch psoriasis:

The condition can develop abruptly.
Symptoms may include fever, chills, weight loss, and muscle weakness.
Patients may develop excessive fluid build-up, protein loss, and electrolyte imbalances. In such cases, hospitalization is required. Fluid and chemical balances must be restored and temperature stabilized as soon as possible.

Zumbusch psoriasis can be life threatening, particularly in the elderly. The condition is very rare in children and, if it occurs, tends to improve more quickly than in adults, possibly even without medication.

Most cases of psoriatic arthritis (PsA) are mild, but complications can occur:

Severe joint deformity and destruction (called arthritis mutilans) may develop, generally in the small joints of the hands and feet. Studies report this happens in about 5 - 16% of patients. Psoriasis patients with other arthritic conditions (osteoarthritis or rheumatoid arthritis) in the joints of the fingers tend to have a higher risk.
People with PsA may have a higher risk for respiratory illnesses.

Some earlier studies indicated that patients with psoriatic arthritis had a shorter lifespan than the general population, but more recent studies found no significant difference.

Black Cohosh Doesn’t Help Hot Flashes

The herbal remedy black cohosh is no better than placebo for treating hot flashes and night sweats, according to a 2006 study in the Annals of Internal Medicine.
Most complementary and alternative medicines are ineffective for relieving menopausal symptoms, according to a 2006 review in the Archives of Internal Medicine.

Hormone Replacement Therapy (HRT)

Short-term use of HRT remains an option for recently menopausal women who have a low risk for stroke, according to a 2007 statement from the North American Menopause Society (NAMS). However, NAMS recommends that women who are at risk for heart disease or breast cancer should consider other approaches for managing hot flashes.
For women who want to discontinue HRT, gradually tapering off the medication or stopping it abruptly appears to make little difference in the recurrence of symptoms, suggests a 2006 study. A gradual approach may delay the reappearance of symptoms, but does not prevent them from returning.

HRT and Heart Disease: Timing Counts

Women who begin HRT within 10 years of menopause have a much lower risk for heart disease and heart attack than women who start HRT later on, indicates a 2007 study in the Journal of the American Medical Association. Experts suggest that HRT is relatively safe for younger women (under age 60) but should not be used by older women. HRT should never be used for prevention of heart disease, and HRT increases the risk for stroke regardless of a woman’s age or when she begins taking it.

HRT and Cancer

A dramatic fall in breast cancer rates has accompanied the decline in HRT use, according to a 2007 study in the New England Journal of Medicine.
Women who use HRT for more than 5 years have a 20% greater risk of developing and dying from ovarian cancer than women who have never used HRT, indicates a 2007 Lancet study of nearly 1 million women.

Introduction

The ovaries contain 200,000 - 400,000 follicles, tiny sacks that contain the materials needed to produce mature eggs, or ova. The ovaries produce two major female hormones: estrogen and progesterone.

The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth.

Estrogen. Estrogens have an effect on about 300 different tissues throughout a woman's body:

They are essential for the reproductive process and for the development of the female organs.
Estrogens determine the characteristic female distribution of body fat on the hips and thighs, which develops during adolescence.
They also are involved in tissues in the central nervous system (including the brain), the bones, the liver, and the urinary tract.

Estrogen has different forms:

The most potent form is estradiol.
The other important, but less powerful, estrogens are estrone and estriol.

Most of the estrogens in the body are produced by the ovaries, but they can also be formed by other tissues, such as body fat, skin, and muscle.

Progesterone. Progesterone, the other major female hormone, is necessary for thickening and preparing the uterine lining for the fertilized egg.

As a woman ages, her supply of eggs declines. Menopause occurs naturally after the woman's supply of follicles has been depleted and menstruation ends completely. (Menopause may also be induced if the ovaries are surgically removed.)

Perimenopause. Menopause does not occur suddenly. A period called perimenopause usually begins a few years before the last menstrual cycle. Some experts believe there are three stages in the transition:

Early Stage. The beginning of perimenopause can begin in some women in their 30s, but most often it starts between ages 40 - 44. It is marked by changes in menstrual flow and in the length of the cycle. There may be sudden surges in estrogen.
Middle Stage. In the middle cycle, periods become irregular but they are not skipped.
Late Stage. In the late stages, women begin missing the periods until they finally stop. About 6 months before menopause estrogen levels drop significantly. The fall in estrogen triggers the typical symptoms of vaginal dryness and hot flashes (which can last from half a year to more than 5 years after onset of menopause).

Menopause. At the point at which menopause occurs, the following hormonal changes occur:

Ovarian secretion of estrogen and progesterone ends.
Once the ovaries have stopped producing estrogens, however, they still continue to produce small amounts of the male hormone testosterone, which can be converted to estrogen (estradiol) in body fat.
In addition, the adrenal gland continues to produce androstenedione (a male hormone), which is converted to estrone and estradiol in the body fat.

Click the icon to see an image of the adrenal glands.

The total estrogen produced after menopause, however, is far less than that produced during a woman's reproductive years.

The average age of women at menopause today is 51.4 years although it can occur as early as age 40 to as late as the early 60s. Women now have a life expectancy of more than 80 years. Currently, women can expect to live some 30 or 40 years of their life in the postmenopausal state.

Menopause is not a disease. However, many conditions are associated with estrogen depletion, including heart disease, osteoporosis, and other complications. Fortunately, effective treatments are available for these conditions.

In a number of studies, most women have reported menopause as a positive experience and have welcomed it with relief and as a sign of a new stage in life.

Complications

After a woman reaches menopause, her average life expectancy is 30 - 40 years. During those years, however, she faces certain health risks due to lower levels of estrogen that cause accelerated bone loss and an increase in LDL cholesterol (the so-called bad cholesterol). Her risks for serious disorders are estimated at 46% for heart disease, 20% for stroke, and 15% for hip fracture. In addition, about 8% of people over 75 have dementia, with postmenopausal women having 1.4 - 3 times the risk for Alzheimer's disease compared to men.

Heart disease is the number one killer of women. In 2003, more than 480,000 women died from diseases of the heart and circulation (cardiovascular diseases). Although young women have a much lower risk for cardiovascular disease than young men, after menopause women catch up. After age 51, women’s risk of dying from heart disease is very close to that of men. Estrogen loss is believed to play a major role in this increased risk.

Some studies indicate that women who reach menopause at an early age are at increased risk of heart disease. However, recent research suggests that the reverse may also be true. A 2006 study suggested that women who have heart disease risk factors (smoking, high total cholesterol levels, high blood pressure) during premenopause may enter menopause earlier than women with healthier heart profiles. [See In-Depth Report #3: Coronary artery disease.]

Estrogen has the following effects:

Harmful Effects on Cholesterol and Other Lipids (Fats in the Blood). About 2 years before menopause, as estrogen levels begin to decline, the levels of the harmful low-density lipoprotein (LDL) cholesterol begin to rise, and the advantageous high-density lipoprotein (HDL) levels decrease.
Positive Effect on Blood Flow. Estrogen has significant effects on smoothing, relaxing, and opening blood vessels, thereby increasing blood flow and reducing pressure.
Antioxidant Actions. Estrogen is also an antioxidant. That is, it helps clean up particles called oxygen-free radicals that are released by natural chemical processes in the body, which can cause significant damage, including harm to the arteries.
Mixed Effects on Blood Pressure. The effects of estrogen on blood pressure are not clear. Oral contraceptives, for instance, which contain estrogen, appear to increase pressure slightly.

Blood pressure is the force applied against the walls of the arteries as the heart pumps blood through the body. The pressure is determined by the force and amount of blood pumped and the size and flexibility of the arteries.

Mixed Effects on Blood Clotting. Estrogen affects many blood-clotting factors in the liver: It reduces blood viscosity (stickiness) and may enhance fibrinolysis, the natural process for breaking down blood clots. Unfortunately, estrogen also has other actions that increase the risk for blood clots. Women who take hormone replacement therapy are at risk for thromboembolism -- blood clots that block a vessel.

This action may explain the higher rates of adverse heart events now observed in women with heart disease who take HRT.

Osteoporosis is a disease of the skeleton in which bones become brittle and prone to fracture. In other words, the bone loses density. At age 65, about 30% of women have osteoporosis, and nearly all of them are unaware of their condition. After age 80, up to 70% of women develop osteoporosis. Osteoporosis is a major risk factor for fracture in the spine and hip. The lifetime risk of spinal fracture in women is about 1 in 3 and that for hip fracture is 1 in 6. Furthermore, between 10 - 20% of women who experience a hip fracture die within a year and about 25% require nursing home treatment.

Experts are still puzzled by the extreme speed-up of bone breakdown (resorption) after menopause. Estrogen may have an impact on bone density in various ways:

Estrogen's most important effect on osteoporosis appears to be prevention of bone break down (resorption). Some research suggests that estrogen may control the lifespan of osteoclasts, the cells responsible for bone breakdown.
Part of estrogen's beneficial actions may involve maintaining normal levels of vitamin D, an important nutrient in bone protection.

Risk factors for osteoporosis include:

Being tall and thin
Being Caucasian
Smoking
Taking thyroid hormone
Being sedentary
Early menopause or surgical menopause (removal of ovaries)

Women at risk for osteoporosis should have a bone density test to measure their bone mass and then make a decision about treatment after consulting their doctor. [See In-Depth Report #18:Osteoporosis.]

Depression may occur as a woman transitions into menopause (perimenopause), even among women with no history of clinical depression. Hormonal changes and declines in estrogen levels are probably involved in this process. Research suggests that a depressive disorder is 2.5 times more likely to develop during perimenopause than premenopause. Women who transition to menopause at a younger age are at increased risk of a first episode of depression.

Symptoms of clinical depression include:

Loss of interest or pleasure in activities once enjoyed
Persistent (longer than 2 weeks) sad mood
Decreased energy
Sleep problems (insomnia or oversleeping)
Feelings of guilt, worthlessness, and hopelessness
Difficulty concentrating

Some of these symptoms may overlap with other symptoms that typically accompany perimenopause. Women who experience these symptoms should talk to their doctor. Depression is treatable. [See In-Depth Report #8: Depression.] For many women, depression eases once they reach menopause.

Estrogen, the primary female hormone, appears to have properties that protect against the memory loss and lower mental functioning associated with normal aging. Estrogen's effects on the brain include:

Laboratory studies suggested that estrogen may help block production of beta-amyloid, the source of the sticky plaques found in Alzheimer's brains.
Estrogen may trigger the temporary growth of nerve pathways in the memory portion of the brain.
Estrogen may stimulate production of the neurotransmitters acetylcholine and serotonin, which are depleted in Alzheimer's patients.
Estrogen also appears to smooth, relax, and open blood vessels, which may help blood flow in the brain.
Estrogen is an antioxidant. That is, it helps clean up free-oxygen radicals, the unstable particles thought to play a role in Alzheimer's.
Studies have been mixed on the association between natural estrogen levels and mental functioning in older women.

Estrogen therapy has been associated with reduced gum bleeding and with decreased bone loss around the teeth, and women who take estrogen are less likely to lose their teeth. Thus, the same principle that helps prevent bone loss in osteoporosis is also at work in preventing bone loss in the mouth.

Estrogen, progesterone, or both appear to protect against cataracts.

Studies also indicate that estrogen helps prevent glaucoma and macular degeneration.

The drop in body estrogen levels brought on by menopause may contribute to both urinary stress and urge incontinence.

Women are at increased risk for recurrent urinary tract infections after menopause. Research suggests that estrogen may prevent infection by increasing the number of lactobacilli, a microorganism that fights infection by preventing bacteria from adhering to vaginal cells.

Estrogen may help prevent slackness and dryness in the skin and reduce wrinkles.

Menopause is associated with more sleeping problems, including inability to fall asleep and nighttime wakefulness.

Symptoms

The most prominent symptoms of the transition to menopause include:

Hot flashes and night sweats. Women often experience hot flashes as an intense build-up in body heat, followed by sweating and chills. Some women report accompanying anxiety as the sensation builds. In most cases, hot flashes resolve within 2 years of menopause, although in some women they may persist for years. Women who have a hysterectomy (surgical removal of the uterus) are less likely to experience hot flashes than women who have a natural menopause. However, women who have surgical removal of both ovaries, and who do not receive hormone replacement therapy, may have more severe hot flashes than women who enter menopause naturally.
Heart pounding or racing can occur, with or without hot flashes.
Difficulty sleeping. Insomnia is common during perimenopause. It may be caused by the hot flashes or it may be an independent symptom of hormonal changes. A 2006 study indicated that severe hot flashes are frequently associated with chronic insomnia.
Mood changes. Mood changes are most likely to be a combination of sleeplessness, hormonal swings, and psychological factors as a woman undergoes this intense passage in her life. Once a woman has reached a menopausal state, however, depression is no more common than before, and women with a history of premenstrual depression often experience significant mood improvement.
Sexuality. Sexual responsiveness tends to decline in most women after menopause, although other aspects of sexual function, including interest, frequency, and vaginal dryness vary. It is useful to remember that the symptoms of menopause eventually go away.
Forgetfulness. This appears to be one of the few symptoms that are common across most cultural and ethnic groups.
Urine leakage.
Vaginal dryness.
Joint stiffness.

Women from different ethnic and or cultural groups report different menopausal symptoms. For example, in one study hot flashes occurred in about 30% of Caucasians and 45% of African-Americans. Hispanic women tended to complain of urine leakage, vaginal dryness, and heart pounding. Japanese and Chinese women experienced far fewer menopausal symptoms, except for forgetfulness. All groups complained about this symptom.

Lifestyle Changes

Simple changes in lifestyle and diet can help control menopausal symptoms such as hot flashes. Avoid hot flash triggers like spicy foods, hot beverages, caffeine, and alcohol. Dress in layers so that clothes can be removed when a hot flash occurs. For vaginal dryness, moisturizers, and non-estrogen lubricants, such as KY Jelly, Replens, and Astroglide are available.

When women reach menopause, they are at increased risk for heart disease. A heart-healthy diet is an important way to control cholesterol and blood pressure levels. [See In-Depth Report #42: Heart-healthy diet.]

In 2007, the American Heart Association (AHA) issued revised diet and lifestyle recommendations. The current guidelines recommend:

Balancing calorie intake and physical activity to achieve or maintain a healthy body weight. (Controlling weight, quitting smoking, and exercising regularly are essential companions of any diet program. Try to get at least 30 minutes, and preferably 60 – 90 minutes, of daily exercise.)
Consuming a diet rich in a variety of vegetables and fruits. Vegetables and fruits that are deeply colored (spinach, carrots, peaches, berries) are especially recommended as they have the highest micronutrient content.
Choosing whole-grain, high-fiber foods. These include fruits, vegetables, and legumes (beans). Good whole grain choices include whole wheat, oats/oatmeal, rye, barley, brown rice, buckwheat, bulgur, millet, and quinoa.
Eating fish, especially oily fish, at least twice a week (about 8 ounces/week). Oily fish such as salmon, mackerel, and sardines are rich in the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Consumption of these fatty acids is linked to a reduced risk of sudden death and death from coronary artery disease. Women with existing heart disease may also consider taking a daily dietary supplement of 850 – 1,000 mg of EPA and DHA.
Limiting daily intake of saturated fat (found mostly in animal products) to less than 7% of total calories, trans fat (found in hydrogenated fats, commercially baked products, and many fast foods) to less than 1% of total calories, and cholesterol (found in eggs, dairy products, meat, poultry, fish, shellfish) to less than 300 mg per day. Choose lean meats and vegetable alternatives (such as soy). Select fat-free and low-fat dairy products. Grill, bake, or broil fish, meat, and skinless poultry.
Using little or no salt in your foods. Reducing salt can lower blood pressure and decrease the risk of heart disease and heart failure.
Cutting down on beverages and foods that contain added sugars (corn syrups, sucrose, glucose, fructose, maltrose, dextrose, concentrated fruit juice, honey).
If you consume alcohol, do so in moderation. The AHA recommends limiting alcohol to no more than 1 drink per day for women.
The AHA does not recommend antioxidant supplements (such as vitamin E, C, or beta carotene) or folic acid supplements for prevention of heart disease.

Soy is an excellent food. It is rich in both soluble and insoluble fiber, omega-3 fatty acids, and provides all essential proteins. Soy proteins have more vitamins and minerals than meat or dairy proteins. They also contain polyunsaturated fats, which are better than the saturated fat found in meat. The best sources of soy protein are soy products (tofu, soy milk, soybeans).

For many years, soy was promoted as a food that could help lower cholesterol and improve heart disease risk factors. But an important 2006 review of studies found that soy protein and isoflavone supplement pills do not really have any effects on cholesterol or heart disease prevention. The AHA still recommends soy foods, but not supplements, as a healthy food choice. The benefits of soy on menopausal symptoms are mixed, according to research (see below in Alternative Therapies). A 2006 study reported that increased soy intake does not help reduce the frequency or severity of hot flashes and night sweats.

Soy is high in estrogen-like plant chemicals called isoflavones, which may improve bone health in older women. A 2005 review of 15 clinical trials found that, although the results were mixed, isoflavones appeared to decrease bone loss, especially in younger postmenopausal women. Soy food products, such as tofu, that also contain calcium may be particularly beneficial.

A combination of calcium and vitamin D is important for helping to prevent bone loss. [See In-Depth Report #18: Osteoporosis.]

Calcium. Women should be sure they have sufficient calcium and vitamin D in their diet by consuming low-fat dairy products or calcium-enriched orange juice. Calcium supplements may be another option for some women. For calcium supplements, calcium citrate (Citracal) is better absorbed than calcium carbonate (Tums, Os-Cal) and other types of calcium compounds. Calcium citrate was the first calcium supplement reported to preserve bone density after menopause.

The standard recommended calcium dose for adults age 50 years and older is 1,000 – 1,500 mg per day, depending on risk factors. High doses (over 2,500 mg per day) of calcium supplements may increase the risk for kidney stones. (Because many commercial foods are now fortified with calcium, this upper limit may be easier to reach than people think.)

For years, doctors have recommended that women take supplements of calcium plus vitamin D to help maintain bone density and reduce the risk for fractures. However, a 2006 New England Journal of Medicine study raised some questions about this approach. In the Women’s Health Initiative study, women were randomly assigned to receive either 1,000 mg of calcium carbonate plus 400 IU of vitamin D a day or placebo. The results indicated that daily calcium and vitamin D supplements:

Improve hip bone density slightly (by 1%)
Prevent hip fracture, but only for women who consistently take the supplements. (Another 2006 study supported this finding.)
Do not prevent spine or other types of fractures
Produce a slight increase in the risk of kidney stones

The medical community has differing views on how to interpret these findings. Some doctors recommend that women over age 60 should still consider taking calcium and vitamin D for bone health. Other doctors feel that due to the risks of kidney stones, supplements are beneficial only for women (especially those over age 70) who do not get enough calcium in their diets. Ask your doctor whether you should take calcium supplements.

Vitamin D. Vitamin D is necessary for the absorption of calcium in the stomach and gastrointestinal tract and is the essential companion to calcium in maintaining strong bones. Some studies suggest that vitamin D protects against osteoporosis only in combination with calcium.

Vitamin D is manufactured in the skin using energy from the ultraviolet rays in sunlight. It can also be obtained from dietary supplements. As a person ages, vitamin D levels decline. Levels also fall during winter months and when people have inadequate sunlight. Pollution may also contribute to less sunlight and declining vitamin D levels.

Daily dosage guidelines vary. General recommendations include:

400 IU for people age 50 - 60
600 IU for those over age 70 who do not have sufficient exposure to sunlight. (Some evidence suggests that higher doses of vitamin D -- up to 800 IU per day -- may help prevent fractures in people with osteoporosis.)
800 – 1,000 IU for adults over age 50 (the amount recommended by the National Osteoporosis Foundation)

Drinking milk fortified with vitamin D and sunlight exposure supply most people's need for vitamin D. (One cup of whole milk provides about 100 IU of vitamin D.) Oily fish (sardines especially, as well as salmon, fresh tuna, and mackerel) are also important dietary sources of vitamin D. Wild salmon has a much higher vitamin D content than farmed salmon.

Effect on the Heart. One drink a day in women who are not at risk for alcohol abuse may be beneficial for the heart. Red wine in particular contains a substance called resveratrol, which is classified as a phytoestrogen and has estrogen-like effects.

Effect on Bones. Alcohol has different effects on bones depending on how much is consumed. A 2004 study found that moderate wine consumption was linked to improved bone mineral density in postmenopausal women. Alcohol, in moderate amounts, may increase estrogen levels. Excessive drinking, however, has been associated with brittle bones.

Effect on Breast Cancer. Women who drink face an increased risk for breast cancer, but the risk associated with mild-to-moderate drinking is small.

Many women need to increase physical activity and reduce caloric intake before and after menopause. Weight gain is common during these years, and it can be sudden and distressing, particularly when habitual exercise and eating patterns are no longer effective in controlling weight. Gaining weight around the abdomen (the so-called apple shape) is a specific risk factor for heart disease and diabetes and many other health problems. A 2007 study suggested that calcium and vitamin D supplements may help prevent weight gain in postmenopausal women. The benefit was greatest for women who had not been getting enough daily calcium in their diets.

For protection against all aging diseases, women, whether or not they are taking hormone replacement therapy, should pursue a lifestyle that includes a balanced aerobic and weight resistance exercise program appropriate to their age and medical conditions. Brisk walking, stair climbing, hiking, dancing, and tai chi are all helpful. Several studies report that exercise can help control hot flashes. A healthy diet plus regular, consistent exercise can also help ward off the weight gain associated with menopause. Weight-bearing exercises are specifically helpful for protecting against bone loss. Women should strive for at least 30 minutes of exercise each day (for weight loss, 60 – 90 minutes is preferred). While more exercise is better, any exercise is helpful. A 2007 study showed that postmenopausal sedentary women who exercised only 75 minutes a week experienced improvement in fitness levels.

If a woman smokes, she should quit. Smoking is linked to a decline in estrogen levels. Women who smoke experience menopause about 2 years earlier than nonsmokers. Smoking doubles a woman’s odds of developing coronary heart disease and is a major risk factor for osteoporosis.

Aspirin. The American Heart Association recommends daily low-dose aspirin for all women age 65 years and older who can safely take aspirin. High-risk women may require 75 – 325 mg per day; lower-risk women may benefit from 81 mg a day or 100 mg every other day.

There are many unproven methods for relieving menopausal symptoms, some more effective than others. Acupuncture, meditation, and relaxation techniques are all harmless ways to reduce the stress of menopause, and some people report great benefit from these practices.

Acupuncture, hypnosis, and biofeedback are all alternative ways to control pain. Acupuncture involves the insertion of tiny sterile needles, slightly thicker than a human hair, at specific points on the body.

Women often try herbal or so-called natural remedies to treat menopausal symptoms. There have been numerous studies conducted on various herbal products and other complementary and alterative therapies. These studies have not found that these approaches have any benefit. Some can have adverse side effects.

Many studies have researched plant estrogens (phytoestrogens), which are generally categorized as isoflavones (found in soy and red clover) and lignans (found in whole wheat and flaxseed). No evidence to date indicates that phytoestrogen supplements provide any benefit for hot flashes or other menopausal symptoms. Nevertheless, foods containing them may be healthful.

Supplements containing specific isoflavones found in soy -- typically the estrogen-like compounds genistein and daidzein -- do not appear to provide any benefits compared to the whole soy protein. Taking them separately may, in fact, cause harm, including a possible increase in estrogen-related cancers.

The following herbs are sometimes use for menopausal symptoms and carry certain risks:

Black cohosh (Cimicifuga racemosa), also known as squaw root, is the herbal remedy most studied for menopausal symptoms. Although it contains a plant estrogen, this substance does not act like an estrogen in the human body. Studies have shown mixed results in preventing hot flashes. A rigorous 2006 study found that black cohosh worked no better than placebo for treating hot flashes and night sweats. While it may be ineffective, black cohosh appears to be safe. Headaches and gastrointestinal problems are common side effects.
Dong quai (Angelica sinensis) does not appear helpful for hot flashes or other menopausal symptoms. Do not use dong quai with blood-thinning drugs, such as warfarin, because it may cause bleeding complications.
Ginseng (Panax ginseng) may help menopausal symptoms of depression and sleep problems, but it has no effect on hot flashes.
Kava (Piper methysticum) may relieve anxiety but it does not help hot flashes. This herb is generally considered unsafe, due to several reports of liver failure and death, especially in people with liver disease.
Wild yam (Dioscorea villosa) is an herb sometimes used for menstrual problems as well as menopausal symptoms. It contains a plant progesterone. However, like black cohosh, there is no evidence that the human body can convert this substance into a hormone. Patients should be aware that some commercial herbal wild yam products contain prescription progesterones.
Dehydroepiandrosterone (DHEA) is a weak male hormone secreted by the adrenal gland. It is available as a dietary supplement. DHEA has no benefit for hot flashes and may increase the risk of breast cancer.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like with drugs, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Patients should check with their doctors before using any herbal remedies or dietary supplements.

Medications

Doctors used to believe that HRT could help reduce the risk of heart disease and other health risks in addition to treating menopausal symptoms. The results of an important study, called the Women's Health Initiative (WHI), led doctors to revise their recommendations regarding HRT.

The WHI, started in 1991, enrolled 161,809 women between the ages of 50 - 79 in 40 different medical centers. Part of the study was intended to examine the health benefits and risks of hormone replacement therapy, including the risks of breast cancer, heart attacks, strokes, and blood clots.

In 2002, one component of the WHI, which studied the use of estrogen and progestin in women who had a uterus, was stopped early because the health risks exceeded the health benefits. The main reason for stopping the estrogen-progestin study was a 26% increase in breast cancer. This combination therapy study also showed an increased risk for heart attack, stroke, blood clots, and dementia. There was a reduced risk for colorectal cancer and bone fractures, but these benefits did not outweigh the considerable risks.

In 2004, a second component of the WHI, which studied estrogen-only therapy in women who no longer have a uterus, was stopped early. This was primarily because of an increase in the risk for strokes and blood clots. The study also found the estrogen-only therapy had no effect on heart attack or colorectal cancer risk. An update in 2006 suggested that estrogen-only therapy does not increase breast cancer risk over the short term (average 7 years) but may increase risk when taken for a longer time (15 years or more). Another WHI update, from 2007, indicated that estrogen-only therapy can help reduce calcium deposits in the coronary arteries (a sign of heart disease) for women in their 50s who have had a hysterectomy. However, women who have a uterus cannot take estrogen-only HRT because it increases the risk for uterine cancer. Combination estrogen-progestin HRT does not have the same benefits for cholesterol reduction as estrogen-only HRT.

While the WHI studies indicate that HRT should not be prescribed for prevention of chronic diseases, many doctors still accept its use for short-term treatment of moderate-to-severe hot flashes and other menopausal symptoms, and in women undergoing premature menopause for medical or other reasons. Current guidelines recommend using the lowest possible dose for the shortest duration of time. A 2007 position statement from the North American Menopause Society (NAMS) supports short-term use of HRT for treatment of hot flashes and other vasomotor symptoms in recently menopausal women who have a low risk for stroke. However, NAMS recommends that women who are at risk for heart disease or breast cancer should avoid hormone therapy and try other options to manage symptoms.

When a woman stops taking HRT, perimenopausal symptoms may recur. There is some debate about whether it is better to abruptly stop the medication or to taper it off gradually. A 2006 study suggested that gradual discontinuation of HRT delays -- but does not prevent -- the reappearance of symptoms. However, when a woman reaches full menopause, symptoms will eventually go away.

Hormones Used in HRT. Hormone replacement therapy uses either estrogen alone (known as ET or unopposed estrogen) or in combination with forms of progesterone (known as combined hormone therapy or EPT). Progesterone is referred to by one of several names:

Progesterone is the name for the natural hormone.
Progestin is the term for any hormone, natural or synthetic, that causes progesterone effects.
Progestogen is any hormone that has effects similar to progesterone.

Both ET and EPT are available in many forms, including oral tablets, skin patches, and vaginal and skin applications. A new form approved by the FDA in 2004 is a topical estrogen gel that is applied to the arm.

HRT is mainly recommended for relieving menopausal symptoms, including hot flashes, night sweats, vaginal dryness, sleep problems, and mild depression. HRT does not prevent certain other problems associated with menopausal changes, such as thinning hair.

Oral hormonal medications and skin patches are equally effective in reducing hot flashes, mild depression, and sleep problems. Progestins may sometimes be prescribed alone for hot flashes and other acute menopausal symptoms, though they can cause side effects, such as mood swings, bloating, and breast tenderness. Estrogen creams, rings, or vaginal tablets restore vaginal elasticity and lubrication and improve sexual pleasure.

HRT may be useful for some women at high risk for osteoporosis, although other drugs, such as bisphosphonates, should be considered first. It increases bone density and also appears to improve balance and protects against falling. Studies also report reductions in fractures (especially hip fractures) among women taking HRT, but the benefits may not outweigh the risks of HRT. It appears that the beneficial effects wear off soon after therapy is stopped. Estrogen must be taken life long for maximum protection against osteoporosis, which then increases the risk for adverse health effects.

Heart Disease. HRT does not prevent heart disease and can increase the risk for heart disease and heart attack, especially in older women. An important 2007 Women’s Health Initiative study in the Journal of the American Medical Association indicated that this risk is time and age dependent. The study found that women who began HRT within 10 years of menopause had less risk of heart disease than women who begin HRT later on. This study suggests that HRT may be safest for women younger than age 60, and should be avoided by women older than age 60. Any woman who is considering HRT should be sure to have her blood pressure and cholesterol levels evaluated.

Another 2007 study, published in the New England Journal of Medicine (NEJM), also indicated that timing is important. The NEJM study found that that estrogen-only HRT may help reduce calcium deposits in coronary arteries in younger women (age 50 - 59) who have had a hysterectomy. (Because of the increased risk for uterine cancer, estrogen-only HRT is only appropriate for women who no longer have a uterus. Women who have a uterus need to take estrogen-progestin HRT. And, estrogen can increase the risk for heart attack in women who have advanced heart disease.) Although the NEJM study found some heart benefits for estrogen-only HRT for younger women, experts still advise that HRT should be used for only a few years. Any woman who is considering HRT should be sure to have her blood pressure and cholesterol levels evaluated.

Stroke. HRT increases the risk of stroke, regardless of years since menopause. In addition, HRT appears to worsen the outlook for women who have had a stroke.

Mental Decline. Observational studies had suggested that hormone replacement therapy (HRT) helped prevent mental decline and even Alzheimer's disease after menopause. Other studies have found no differences in mental performance and no protection from Alzheimer's disease in women taking HRT compared to non-users. A 2004 review of the Women’s Health Initiative Memory Study found that combined HRT did not reduce the risk of cognitive impairment, and actually increased the risk of dementia among women ages 65 and over.

Thromboembolism. HRT is associated with a higher risk for thromboembolism, in which blood clots form in deep veins. This places women at risk for pulmonary embolism, in which the blood clot travels to the lungs.

Click the icon to see an image of a pulmonary embolism.

Breast Cancer. Because breast tissue growth is highly sensitive to estrogens, the more a woman is exposed to estrogen over her lifetime, the higher the risk for breast cancer. A number of studies have reported a higher risk for breast cancer in postmenopausal women taking HRT that contains both estrogen and progestin. A combination of estrogen and testosterone also increases breast cancer risk. A 2005 study suggested that HRT with no or low progestin is safer than standard estrogen-progestin combination therapy.

Several 2006 studies of women who had a hysterectomy indicated that estrogen alone does not increase overall breast cancer risk when the drug is used for 7 years or less. However, women who take the drug for 15 years or more do have an increased risk. Women who are at low risk for breast cancer tend to have fewer breast cancers with estrogen alone, while women at higher risk tend to have more breast cancers. In addition, estrogen therapy may cause abnormal mammogram results. Breast tissue density increases with HRT, which makes mammograms more difficult to read and leads to more breast biopsies. Women who take estrogen HRT should be aware that they need frequent mammogram screenings.

As further evidence of the association between HRT and breast cancer, a 2007 New England Journal of Medicine study noted that breast cancer rates have fallen as HRT use has declined.

Endometrial (Uterine) Cancers. Estrogen overstimulates the tissue lining the uterus (the endometrium) and causes uncontrolled cell growth, a condition known as hyperplasia, which is a strong risk factor for cancer. Taking unopposed estrogen replacement therapy (ERT) increases the risk of endometrial cancer at least five-fold. Adding progestin to HRT appears to pose no risk for this cancer. However, a 2007 study indicated that short-term treatment (3 years) with ERT is associated with a relatively low risk of endometrial cancer. Women who take ERT should anticipate uterine bleeding, especially if they are obese, and may need endometrial biopsies and other gynecologic tests.

Ovarian Cancer. HRT appears to increase the risk for ovarian cancer. A 2007 UK study of nearly 1 million women found that women who used HRT for more than 5 years were 20% more likely to develop and die from ovarian cancer than women who had never taken HRT.

Gallstones. HRT is associated with a higher risk for gallstones.

Despite its risks, hormone replacement therapy appears to be the best treatment for hot flashes. Nonhormonal treatments for hot flashes and other menopausal symptoms include:

Antidepressants. The antidepressants known as selective serotonin-reuptake inhibitors (SSRIs) are sometimes used for managing mood changes and hot flashes. They include fluoxetine (Prozac), sertraline (Zoloft), venlafaxine (Effexor), and paroxetine (Paxil, Asimia). A 2006 review of nonhormonal therapies, found that paroxetine in particular may help hot flashes. However, paroxetine, like other antidepressants, can cause headache, anxiety, and sexual problems. A 2007 study suggested that the antidepressant citalopram (Celexa), given alone or with HRT, may help treat hot flashes.

An investigational antidepressant, desvenlafaxine (Pristiq), is also being studied for treatment of hot flashes, night sweats, and perimenopausal sleep problems. Research presented at the 2007 meeting of the American College of Obstetricians and Gynecologists indicated that desvenlaxafine, which is related to venlaxafine, showed promise in improving symptoms.

Gabapentin.Several small studies suggest that gabapentin (Neurontin), a drug used for seizures and nerve pain, may relieve hot flashes. Gabapentin may cause drowsiness, dizziness, fatigue, and swelling of the hands and feet.

Clonidine. Clonidine (Catapres) is a drug used to treat high blood pressure. Studies show it may help manage hot flashes. Side effects include dizziness, drowsiness, dry mouth, and constipation

Testosterone. Some doctors prescribe combinations of estrogen and small amounts of the male hormone testosterone to improve sexual function and increase bone density. Side effects of testosterone include increased body hair, acne, fluid retention, anxiety, and depression. Testosterone also adversely affects cholesterol and lipid levels. A 2006 study indicated that combined estrogen and testosterone can increase the risk of breast cancer.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Sexually transmitted diseases (STDs) are infectious diseases that are spread through sexual contact. STDs are among the most common infectious diseases in the world today. There are over 20 types, affecting more than 13 million men and women in the United States alone each year, and the incidence is on the rise. Some of the most common STDs include chlamydial infection, genital herpes, genital warts, gonorrhea, HIV (human immunodeficiency virus, the microorganism that causes AIDS), and syphilis.

Signs and Symptoms

STDs often occur without symptoms, particularly in women. However, STDs may be accompanied by the following signs and symptoms:

Itching
Discharge
Pustules (pus-containing blisters)
Genital lesions including ulcers, blisters, rashes, and warts. Ulcers may be painful.
Abdominal pain
Rectal infection and inflammation of the rectum
Fever
Muscle pain
Painful urination
Swollen lymph glands in the groin

What Causes It?

STDs are caused by microbial agents and spread primarily (but not exclusively) through sexual contact. Some STDs can also be passed from a mother to her baby during delivery and through breastfeeding while infected. Others may be passed by sharing infected needles. Some of the most common STDs and the microorganisms that cause them are listed below.

AIDS: human immunodeficiency virus (HIV)
Chlamydial infection:Chlamydia trachomatis
Genital herpes: herpes simplex virus (HSV)
Genital warts: human papillomavirus (HPV)
Gonorrhea:Neisseria gonorrhoeae
Syphilis:Treponema pallidum

In addition, there are certain infections classified as STDs that may be sexually transmitted but often are not. Candidal (yeast) infections and Gardnerella (an organism that frequently lives in the vagina) are examples that may cause vaginal inflammation.

Who's Most At Risk?

People with the following conditions or characteristics are at risk for developing STDs:

Having a sexual partner with an STD. In many cases, an STD may be present without symptoms.
Having many sexual partners, or a partner who has many sexual partners.
Having sex without the use of condoms or other protective devices.
Having one STD increases the likelihood of contracting another.
Adolescents are at highest risk for acquiring an STD for the first time.
Living under stress from poverty, poor nutrition, or poor or absent health care.
Practicing anal intercourse increases risk for HIV, gonorrhea, and syphilis.
Having a weakened immune system.
Using intravenous drugs.
Using spermicidal foams and jellies does not protect against STDs and may, in some cases, even promote contraction of certain STDs, including HIV.

What to Expect at Your Provider's Office

Your health care provider will do an examination and check for physical signs. Blood tests and other diagnostic procedures, including cultures from the genitalia, can reveal the microbial agent responsible for the STD and allow the health care provider to select the right therapy.

Treatment Options

Prevention

There are many ways in which people at risk may reduce the likelihood of contracting or spreading STDs:

Have a mutually monogamous sexual relationship with an uninfected partner.
Correctly and consistently use a male or female condom for every act of oral, anal, or vaginal intercourse.
Use clean needles if injecting intravenous drugs.
Prevent and control other STDs.
Have regular checkups for STDs even if you have no symptoms, especially if you are having sex with a new partner or with multiple partners.
Learn the common symptoms of STDs and seek medical help immediately if you develop any symptoms.

Anyone diagnosed with an STD should be treated, avoid sexual activity while being treated, notify all recent sexual partners, complete the course of any medications prescribed, and take a follow-up test.

Drug Therapies

STDs are generally treated with antibiotics and antivirals. See the monograph on HIV and AIDS for details on how that condition is treated.

Complementary and Alternative Therapies

There are some possible applications of CAM therapies in the case of STDs -- as adjunctive treatment (antibacterial and antiviral), as prevention, to improve the immune system, or to reduce certain complications, such as arthritis from gonorrhea. There are also CAM therapies for the treatment of specific STDs, including HIV/AIDs, human papillomavirus, and herpes viral infections. Check with your health care provider about which supplements to use for your condition, and about the interaction of supplements with prescription and non-prescription drugs. It is important to remember that not one of these CAM approaches offers a cure or an isolated treatment option. They should not be used instead of seeing your health care provider. Even during treatment, STDs remain highly contagious -- and you must take the necessary precautions to prevent transmission to sexual partners (see section on Prevention).

Always tell your health care provider about the herbs and supplements you are using or considering using.

Nutrition and Supplements

Following these nutritional tips may help improve general health and wellbeing:

Try to eliminate all suspected food allergens, including dairy, wheat (gluten), soy, chocolate, corn, preservatives, and food additives. Your health care provider may want to test you for food allergies.
Eat more antioxidant-rich foods (such as green, leafy vegetables and peppers) and fruits (such as blueberries, tomatoes, and cherries).
Avoid refined foods, such as white breads, pastas, and sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy), or beans for protein.
Use healthy cooking oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise moderately, if tolerated, at least 30 minutes daily, 5 days a week.

You may be able to address nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-vitamins, and trace minerals, such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tablespoonful oil two to three times daily, to help decrease inflammation and improve immunity. Cold-water fish, such as salmon or halibut, are good sources.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant and for immune support.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant, immune, and muscular support.
Acetyl-L-carnitine, 500 mg daily, for antioxidant and antiviral activity.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Resveratrol (from red wine), 50 - 200 mg daily, for antioxidant and antiviral effects.
L-theanine, 200 mg one to three times daily, for nervous system support.
Melatonin, 2 - 5 mg one hour before bedtime, for sleep and immune protection.

Herbs

Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day.

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anti-inflammatory and immune effects. Use caffeine free products. You may also prepare teas from the leaf of this herb.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support and antiviral effects.
Holy basil (Ocimum sanctum) standardized extract, 400 mg daily, for anti-stress and antiviral protection.
Reishi mushroom (Ganoderma lucidum), 150 - 300 mg two to three times daily, for inflammation and immunity. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Cat's claw (Uncaria tomentosa) standardized extract, 20 mg three times a day, for inflammation and antiviral activity.
Garlic (Allium sativum), standardized extract, 400 mg two to three times daily, for antibacterial or antifungal and immune activity.

Traditional Chinese Medicine (TCM) uses many herb combinations to strengthen and tonify the immune system, and as antiviral agents. Check with your health care provider for more information on TCM.

Homeopathy

Homeopaths use various homeopathic remedies to treat STDs. However, so far no scientific studies have evaluated homeopathy for this purpose. An experienced homeopath would consider each individual case and may recommend treatments to address both the underlying constitution and the specific symptoms of the STD.

Acupuncture

Acupuncture may be used to alleviate symptoms and help enhance our natural ability to fight infection. Acupuncture has been reported to be effective in relieving symptoms of STDs, improving immune function, and decreasing the severity of the STD. Check with your health care provider for more information.

Prognosis/Possible Complications

When they are diagnosed early, many STDs can be treated effectively. However, many possible complications can result from not treating STDs. Some types of STDs commonly recur. Some can result in permanent damage to the reproductive organs and infertility. Having other STDs increases the risk for becoming infected with HIV. Antibiotic resistance by organisms that cause certain STDs may interfere with the effectiveness of treatment.

Following Up

Depending on the type of STD you have, your health care provider may want to see you for follow-up visits to be sure the disease has not recurred or to continue your treatment. If you are pregnant, an STD can cause serious complications for your unborn baby. Your health care provider will discuss treatment options with you.
