Cellulitis revealing a cryptococcosis-related immune reconstitution inflammatory syndrome in a renal allograft recipient

Abstract

Immune reconstitution inflammatory syndrome (IRIS) has rarely been described in the course of disseminated cryptococcosis in solid organ transplant recipients. We report here the case of a renal transplant recipient who developed severe cellulitis in the context of Cryptococcus neoformans-associated IRIS while undergoing reduction of his immunosuppressive therapy. IRIS appeared concomitantly with a dramatic increase of blood CD4+ T cells (94-460/mm 3) and required the administration of a short-term steroid therapy to resolve. © 2007 The Authors.
