Visceral leishmaniasis in renal transplant recipients: clinical aspects, diagnostic problems, and response to treatment

Abstract

Visceral leishmaniasis (VL) is a parasitic infection that uncommonly affects renal transplantation recipients, even in endemic areas. It may be associated with other infections, or masked by these, and may present subclinically and/or atypically for extended periods. The evolution may be particularly severe and diagnosis is often delayed. If not adequately diagnosed and treated, VL can be fatal and so should be suspected in renal transplantation recipients presenting unexplained fever, splenomegaly, and pancytopenia. The authors report 8 cases of VL out of a total of 800 renal transplant recipients from two transplant hospitals centers in Brazil. The clinical, diagnostic, and therapeutic features are reviewed.
