Apparent exacerbation of Hansen's disease despite appropriate antimicrobial therapy.
In 1991, the World Health Organization and its member states resolved to reduce the global prevalence of Hansen's disease (leprosy) by at least 90%. Despite its waning prevalence, however, the disease remains endemic in parts of Africa, Asia, and Latin America. Moreover, imported cases are occasionally encountered innonendemic areas. This fact, coupled with the current tempo of overseas deployments, makes it imperative that military physicians familiarize themselves with both the presentation and potential complications of Hansen's disease. Here, we present the case of a soldier referred to Walter Reed Army Medical Center for apparent worsening of his disease despite appropriate antibiotic therapy. On evaluation, the patient was diagnosed with reversal reaction, an immune-mediated phenomenon resembling disease exacerbation and requiring prompt intervention to avert lasting sequelae. Following the case presentation, we discuss the clinical manifestations, pathophysiology, and management of reversal reactions as well as the related entity erythema nodosum leprosum.
