Renal involvement in leprosy.

ABSTRACT

Renal involvement was studied in 70 patients with leprosy by urine analysis, detailed biochemical investigations and renal histopathology. Of these 70 patients, 40 had lepromatous and 30 had non-lepromatous leprosy. Creatinine clearance was reduced in 20 patients. Renal biopsies were studied in 50 cases (25 lepromatous, 25 non-lepromatous); of which in 13 cases (10 lepromatous, 3 non-lepromatous) abnormal histopathological lesions were found by light microscopy. Amyloidosis was seen in only one lepromatous patient. No acid-fast bacilli and leproma like lesion were demonstrated in any case.
