The aim of the study was to determine the various histopathological lesions in human immunodeficiency virus (HIV) patients with renal dysfunction and to establish clinicopathological correlation. Over a period of two years from January 2008 to March 2010, 27 HIV positive patients with renal dysfunction were subjected to renal biopsy. Of the 27 patients, 23 were males and four were females (85.2% males, 14.8% females). Mean age was 38.2 ± 10.36 (range 20 - 60) years. The probable mode of acquisition of HIV infection was sexual in 22 patients (81.5%). Thirteen patients (48%) had nephrotic proteinuria. The CD4 count ranged from 77 to 633/microliter. The kidneys were of normal size in 19 (70.4%) and bulky in eight (29.6%) patients. Thirteen patients required renal replacement therapy. Eleven patients had acute tubule-interstitial lesions (40.7%) while 15 (55.5%) had glomerular lesions. The various glomerular lesions were, focal segmental glomerulosclerosis in five, amyloidosis in three, diffuse proliferative GN in two, and membranoproliferative glomerulonephritis (GN), membranous GN, minimal change disease, diabetic nephropathy, crescentic GN, and thrombotic microangiopathy were seen in one each. None of the clinical or laboratory variables, except hypertension, was found to predict glomerular versus non-glomerular lesions on biopsy. In conclusion we show that a variety of glomerular and tubulointerstitial lesions can be seen on renal histology. Hence, renal biopsy is indicated in renal dysfunction associated with HIV for making proper diagnosis and therapy.
