Renal involvement in leprosy: report of progression from diffuse proliferative to crescentic glomerulonephritis.

Abstract

Renal involvement in leprosy has been reported rarely in the literature. Acute kidney injury in patients with leprosy is uncommon and may occur due to acute tubular necrosis, drug-induced interstitial nephritis and rarely crescentic glomerulonephritis. The latter with histologic confirmation of the diagnosis has been reported in very few cases of leprosy. A 25-year-old male, on therapy for multibacillary leprosy, was found to have deranged renal functions on evaluation for a history of nausea, vomiting, swelling and episode of haematuria. Kidney biopsy was performed twice over a period of 2 weeks, showing progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis, pauci-immune in nature. The patient was treated aggressively with intravenous steroids, following which his renal functions stabilized. Crescentic glomerulonephritis, an extremely rare phenomenon in leprosy, should be considered in these patients presenting with features of acute kidney injury. Timely performed renal biopsy assists in accurate diagnosis and appropriate management of the patient, hence preserving renal parenchyma. Rapid progression from diffuse proliferative glomerulonephritis to crescentic glomerulonephritis in a patient with leprosy is described herein for the first time in the literature.
