[Secondary amyloidosis with irreversible acute renal failure caused by visceral leishmaniasis in a patient with AIDS].

We report a case of visceral leishmaniasis and acute renal failure in a white male patient, 28 years of age, infected with the human immunodeficiency virus (HIV). The clinical presentation of the patient was diarrheic syndrome of long evolution, fever, hepatosplenomegaly and pancytopenia, accompanied by nephrotic syndrome and irreversible acute renal failure. Renal biopsy showed glomerular AA amyloid deposits. This is the first case described in humans of secondary amyloidosis caused by visceral leishmaniasis.
