A new therapeutic approach to type II leprosy reaction

Abstract

Background: An increase in tumor necrosis factor (TNF) has been implicated in type 11 leprosy reaction. Thalidomide, which inhibits TNF, is an effective drug, but has severe side-effects in pregnant women. Other therapeutic drugs are required. Methods: Clofazimine and pentoxifylline were evaluated for their efficacy against severe type 11 leprosy reaction in four patients (three men and one woman). Results: All four patients showed a similar fast response to treatment. Conclusions: The results obtained in this study are promising; however, clofazimine and pentoxifylline must be evaluated in a larger group of patients in order to determine their value in controlling type II leprosy reaction.
