Psoriasis

Psoriasis is a chronic, autoimmune disease of the skin and joints, characterized by raised, red patches (plaques) covered with an often thickened silvery-white scale. Normally skin replaces itself every 27-30 days, however, in psoriasis the skin turns over every 5-6 days. It should be noted that while the cells are dividing more rapidly, similar to cancer cells, they do not become malignant. Psoriasis occurs most often on the extensor areas of the body such as elbows and knees and back of the scalp. The average age of onset is 27 but it may first appear in infancy or in old age. It affects approximately two percent of the world’s population. Psoriasis is not contagious.

Psoriasis

Psoriasis can affect almost any area of the body. Frequently, it is merely a nuisance disease. However, it can certainly affect one’s quality of life, especially if it is extensive, in visible areas, or accompanied by psoriatic arthritis. Up to one third of patients with psoriasis have arthritis.  And patients with psoriasis are more prone to metabolic syndrome characterized by obesity, hypertension, diabetes, and elevated triglycerides.

 

Due to its chronic nature, psoriasis can be challenging to treat. The most common treatments include topical preparations such as corticosteroids, calcium-containing salves, and retinoids (derivatives of vitamin A); light therapy such as Goeckerman (crude coal tar plus UVB) or PUVA (psoralens plus ultraviolet A) or narrowband ultraviolet light; antimetabolites such as methotrexate; immunosuppressants such as cyclosporine; oral retinoids; and the immunobiologic agents such as etanercept (Enbrel®), adilumumab (Humira®), infliximab (Remicade®), ustekinumab (Stelara®),  secukinumab (Cosentyx®),  ixekizumab (Taltz®) and the phosphodiesterase inhibitor 4 (Otezla®).
