Morphologic findings in the kidneys of 138 consecutive acquired immunodeficiency syndrome (AIDS) autopsies performed at the Mexico City General Hospital between 1986 and 1991 were studied. A total of 87 cases (63%) had renal disease, 62 cases presented glomerular alterations, and 80 cases showed tubulointerstitial damage. Glomerular collapse was seen in 30 cases (48%), mesangial expansion in 22 cases (35%), focal and segmental glomerulosclerosis in 20 cases (32%) and glomerular proliferation in only eight cases (11%). Nephrocalcinosis was seen in 25 cases (31%). Thirty-six cases (45%) presented tubulointerstitial infections: Mycobacterium tuberculosis in 19 cases (23%), Cryptococcus in 10 cases (12.5%), Cytomegalovirus CMV in eight cases (10%), Gram-negative bacteria in 3 cases (3.7%), and one case with histoplasmosis. In six cases the pathogens were multiple. Two cases showed infiltration of large-cell non-Hodgkin lymphoma. Based on the results obtained by autopsies, we conclude that in our country there is a high frequency of renal affection in AIDS patients. Clinically, this disease is infrequently diagnosed and not always related to the cause of death.
