Oral administration of cyclosporin a in patients with severe alopecia areata

摘要

abstract_textpAlopecia areata is a chronic, nonscarring hair loss condition with an unpredictable course that may cause emotional stress in affected patients. Regarding its pathogenesis, the most accepted theory is that alopecia areata is a T-cell-mediated autoimmune condition that is most likely to occur in genetically predisposed Individuals. Cyclosporin A is an immunosuppressive agent that has provided new approaches in the treatment of autoimmune diseases. Hypertrichosis, one of the common side effects of orally administered cyclosporin A, encouraged a number of investigators to use the drug in the treatment of alopecia areata, but the reports on this subject have been controversial. We present a small series of patients with severe alopecia areata treated systemically with cyclosporin A at a dose of 3-5 mg/kg for 6 months as well as their 3-month follow-up after cessation of the drug./p/abstract_text
