Abnormalities of renal function have been demonstrated inpatients with visceral leishmaniasis; although there was a trend toward normalization following antiparasitic therapy, some abnormalities persisted. With thepurpose of studying the long- term clinical course of renal involvement in visceral leishmaniasis, 32 patients with a diagnosis of this parasitic disease were evaluated in the endemic area and at least 6 months after the clinical cure of the disease and compared with a control group of 28 individuals. No patient had a history or clinical findings suggestive of renal disease and all were normotensive. Laboratory evaluation was normal in all except 3 patients with abnormal urinalysis. Mild proteinuria and microscopic hematuria were seen in a single urinalysis in one patient (although three other urinalysis were normal), and leucocyturia in two female patients. It was concluded that the renal involvement in visceral leishmaniasis is mild and transient, with normal renal function observed on long-term follow-up after cure of the parasitic infection.
