Psoriasis is the most common autoimmune disease in the United States and affects both children and adults. Its prevalence is approximately 2 percent or 7.5 million Americans. Nearly three percent of the world's population, or 125 million people, have psoriasis. It is a chronic, lifelong disease that varies in severity and response to treatment from person to person. Although not contagious, its exact cause is not entirely known.
Research has clearly demonstrated that psoriasis is more common in families with members affected by psoriasis. About one third of patients report having a relative with psoriasis. For example, if one parent has psoriasis, a child has about a 10 percent chance of having the disease. If both parents have psoriasis, a child has an approximately 50% chance of developing the disease.
The age of onset of psoriasis is variable, with most patients noticing characteristic skin lesions in late adolescence and early adulthood (15-35 yrs old). However, psoriasis may also develop during infancy and middle age. Most people develop thick patches of red skin which have a silvery-white scaly surface. These red, scaly patches are most typically seen on the elbows, knees and trunk, but can appear anywhere on the body, including the scalp and genitals.
People with psoriasis are also at risk for developing an associated inflammatory joint disease, called psoriatic arthritis. This type of arthritis can cause slow destruction of the joints due to chronic inflammation and result in disability. Psoriatic arthritis occurs in 10 to 30 percent of patients with psoriasis.
Facts about psoriasis
Psoriasis is not a cosmetic problem. Nearly 60 percent of people with psoriasis report that the disease has a negative impact on their quality of life.
- Most common autoimmune disease in U.S.
- Onset at any age
- Chronic, lifelong disease
- Not contagious
- Genetic and environmental factors suspected
- Skin lesions may occur anywhere on the body
- Increased risk for arthritis
- Psoriasis and environmental factors
Environmental factors that may trigger a psoriasis outbreak or create a challenge to treatment include:
- Viral or bacterial infections
- Skin injuries such as insect bites, burns, or cuts
- Some medications, including beta blockers, lithium and antimalarial drugs
- Immunosuppression: HIV, cancer chemotherapy
Therapy for psoriasis should always be directed towards the clearance of skin lesions as well as eliminating associated symptoms such as joint pain and arthritis.
Recent scientific advances in our understanding of psoriasis have led to the development of a new class of highly effective drugs for this disease, referred to as biologic agents. Biologic therapy has revolutionized the treatment of psoriasis. These medications are not only effective in clearing skin lesions, but also ameliorate the debilitating symptoms of psoriatic arthritis. Biologic agents include Enbrel, Humira, Remicade and Stelara, among others.
When biologic therapy is not indicated, many patients obtain effective psoriasis treatment with topical medications, XTRAC laser treatment, phototherapy using narrow band ultraviolet B (UV-B), as well as established systemic drugs such as methotrexate and cyclosporine. Psoriasis patients are thoroughly evaluated by our experienced dermatologists to determine which treatment is most appropriate.
- Topical prescription medications
- XTRAC laser treatment
- Narrow band UVB phototherapy
- Biologic therapy (Enbrel, Stelara, Humira)
