Aldara for the Treatment of Extensive Alopecia Areata

Study Overview
=================
Brief Summary
-----------------
We propose to examine the efficacy and tolerability of Aldara Cream 5% for the treatment of extensive alopecia areata. Aldara is a immune-response modifier. The drug induces the production of cytokines which are small, hormone-like proteins involved in cellular communication during immune responses. We hypothesize that this drug will effect the inflammatory cells present around hair follicles in patients with alopecia areata.

Detailed Description
-----------------
Ten patients with extensive scalp alopecia areata (>95% hair loss)of less than 2 years duration will be invited to participate in this study. For six months each person will be asked to apply Aldara Cream 5% daily to the right half of the scalp. No drug will be applied to the left side. Skin biopsies will be taken of the right scalp before and at the completion of the therapy.
