Curbing the psoriasis cascade

PREVIEW

Psoriasis, a T-cell-mediated disorder, affects 1% to 3% of the world's population. The characteristic lesions occur in many different forms, can cause significant discomfort and social distress, and in some instances, lead to dehydration and metabolic derangement. A chronic, unpredictable course and the necessity of periodically switching drugs or classes of drugs make psoriasis frustrating to treat. However, topical and systemic drug therapies and phototherapy can help minimize the exacerbations and prolong remissions. In this article, Dr Shenenberger outlines treatment approaches and discusses research into the use of immunomodulatory agents.
