Membranoproliferative glomerulonephritis due to visceral leishmaniasis in an HIV patient

Abstract

Objective: Rare disease Background: Visceral leishmaniasis is an important opportunistic disease in HIV-positive patients. The information available on the effects of such co-infection in the kidney is limited. We describe a patient with HIV/leishmania coinfection who developed nephrotic syndrome and membranoproliferative glomerulonephritis. As far as we know, only 2 cases of this nephropathy in HIV/leishmania coinfection have been reported. Case Report: A 47-year-old man developed nephrotic syndrome. He had been diagnosed with HIV infection and visceral leishmaniasis and was treated with antiretroviral therapy, antimonial compounds, liposomal amphotericin B and miltefosine, but the leishmania followed a relapsing course. Renal biopsy disclosed membranoproliferative glomerulonephritis and leishmania amastigotes were seen within glomerular capillary lumens. He was given miltefosine and liposomal amphotericin B but the leishmaniasis persisted. Stage 3B chronic renal disease and nephrotic range proteinuria tend to become stable by 15-month follow-up. Conclusions: Our case illustrated some aspects of leishmaniasis in HIV patients: its relapsing course, the difficulties in therapy, and the renal involvement
