Between January 1982 and December 1983, 75 patients with the acquired immunodeficiency syndrome were identified in our hospitals: 35% used intravenous drugs, 50% had proteinuria in excess of 0.5 g/dL, and 10% were nephrotic. Glomerular changes seen at autopsy in 36 patients included frequent mesangial lesions and deposits associated with mild asymptomatic proteinuria. Focal and segmental glomerular sclerosis was found in 5 patients and 4 of these had the nephrotic syndrome. Whereas reversible episodes of acute renal failure were not uncommon, terminal episodes of acute renal insufficiency occurred in 14 patients. The short survival of these patients may prevent the development of chronic renal failure.

Twenty Haitian patients, hospitalized from 1 April 1980 to 20 June 1982, had Pneumocystis carinii pneumonia, central nervous system toxoplasmosis, esophageal candidiasis, cryptococcosis, disseminated cytomegalovirus, progressive herpes simplex virus, chronic enteric coccidiosis, or invasive Kaposi's sarcoma. Ten patients died. Opportunistic infections were frequently multiple and were recurrent in three patients. In seven patients disseminated tuberculosis preceded the other infections by 2 to 15 months. There was no evidence of an underlying immunosuppressive disease, and no history of homosexuality or intravenous drug abuse. At least three patients probably acquired the syndrome in Haiti. Lymphadenopathy was common. Seventeen patients tested had anergy, and 18 had lymphopenia. Monoclonal antibody analysis of peripheral-blood T-cell subsets done on 11 patients showed a marked decrease in T-helper cells and an inversion of the normal ratio of T-helper cells to T-suppressor cells. This syndrome among heterosexual Haitians is strikingly similar to the syndrome of immunodeficiency described recently among American homosexuals.
