Therapy of visceral leishmaniasis in renal transplant recipients intolerant to pentavalent antimonials.

Visceral leishmaniasis should be suspected in renal transplant recipients in whom a fever develops of unknown origin. A 53-year-old renal transplant recipient developed pyrexia, hepatosplenomegaly, and pancytopenia 4 years after transplantation. Antileishmaniasis serology was negative, and the diagnosis was confirmed through bone marrow examination. Treatment with glucantine (N-methylglucamine antimoniate) led to acute pancreatitis, and treatment with ketoconazole plus allopurinol for 21 days was effective to eradicate Leishmania donovani.
