Psoriasis

Definition

Psoriasis is a skin condition that causes skin redness and irritation. Most people with psoriasis have thick, red skin with flaky, silver-white patches called scales.

Alternative Names

Plaque psoriasis

Causes

Psoriasis is very common. Anyone can get it, but it most often begins between ages 15 and 35.

Psoriasis is not contagious. You cannot get it from another person or spread it to others.

Psoriasis seems to be passed down through families. Doctors think it may be an autoimmune condition. This occurs when the immune system mistakenly attacks and inflames or destroys healthy body tissue.

Normal skin cells grow deep in the skin and rise to the surface about once a month. When you have psoriasis, this process takes place too fast. Dead skin cells build up on the skin's surface.

These conditions may trigger an attack of psoriasis or make the condition harder to treat:

Psoriasis may be worse in people who have a weak immune system. This may be due to:

Some people with psoriasis may also have arthritis. This is called psoriatic arthritis.

Symptoms

Psoriasis can appear suddenly or slowly. Many times, it goes away and then comes back.

The main symptom of the condition is irritated, red, flaky patches of skin. These patches appear most often on the elbows, knees, and middle of the body. But they can appear anywhere, including on the scalp.

The skin may be:

Other symptoms may include:

There are five main types of psoriasis:

Exams and Tests

Very often your health care provider can diagnose this condition by looking at your skin.

Sometimes, a skin biopsy is done to rule out other possible conditions. If you have joint pain, your doctor may order x-rays.

Treatment

The goal of treatment is to control your symptoms and prevent infection.

Three treatment options are available:

TREATMENTS USED ON THE SKIN (TOPICAL)

Most of the time, psoriasis is treated with medicines that are placed directly on the skin or scalp. These may include:

SYSTEMIC (BODY-WIDE) TREATMENTS

If you have very severe psoriasis, your doctor will likely recommend medicines that suppress the immune system's faulty response. These medicines include methotrexate or cyclosporine. Retinoids can also be used, but these work differently from medicines that suppress the immune system.

Newer drugs called biologics are used when other treatments do not work. Biologics approved for the treatment of psoriasis include:

PHOTOTHERAPY

Some people may choose to have phototherapy. This treatment:

OTHER TREATMENTS

If you have an infection, your doctor will prescribe antibiotics.

AT HOME CARE

Following these tips at home may help:

Support Groups

Some people may benefit from a psoriasis support group.

Outlook (Prognosis)

Psoriasis can be a life-long condition that can be controlled with treatment. It may go away for a long time and then return. Sometimes it goes away and never returns. With proper treatment it will not affect your overall health.

When to Contact a Medical Professional

Call your health care provider if you have symptoms of psoriasis or if your skin irritation continues despite treatment.

Tell your doctor if you have joint pain or fever with your psoriasis attacks. If you have psoriatic arthritis with symptoms of arthritis (such as painful, stiff, or swollen joints), talk to the provider who is treating your psoriasis.

Go to the emergency room or call the local emergency number (such as 911) if you have a severe outbreak that covers all or most of your body.

Prevention

There is no known way to prevent psoriasis. Keeping your skin clean and moist and avoiding your specific psoriasis triggers may help reduce the number of flare-ups.

Health care providers recommend daily baths or showers for people with psoriasis. Avoid scrubbing too hard, because this can irritate the skin and trigger an attack.
