Development of Leprosy and Type 1 Leprosy Reactions after Treatment with Infliximab: A Report of 2 Cases

Abstract

Humanized monoclonal antibodies to tumor necrosis factor- alpha are valuable for the treatment of rheumatologic conditions, but they have been associated with the development of serious infections. We report the first 2 cases of leprosy developing after treatment with infliximab. After discontinuation of infliximab, both patients developed type 1 ("reversal") leprosy reactions.
