Therapy of alopecia areata with diphencyprone.

Abstract

The properties of diphencyprone (DPC), its possible mechanism of action in the therapy of alopecia areata (AA), and its side-effects are summarized. The results of our own study of treatment in 45 patients with AA, with a mean treatment duration of 72 (15-146) weeks, are presented, and compared with the results of previous studies. We suggest that, in future, therapy protocols should define entry criteria and therapy results more precisely, and include follow-up assessments to establish the length of remission. In view of the low response rates and short lengths of remission, the indications for DPC therapy should be set more rigorously.
