Geographical pathology profile of AIDS in Puerto Rico: the first decade.
Postmortem histopathological changes in 100 adult patients with AIDS who died in Puerto Rico from 1982 to 1991 were studied and tabulated. Modes of HIV transmission were reviewed. Patient ages ranged from 21 to 60 yr. Gender composition for the patient group was 83 men (average age, 35 yr) and 17 women (average age, 39 yr). Sixty-eight of the patients were injecting-drug users, 20 were homosexual and bisexual men, seven were women who had had heterosexual contact with men at risk for HIV, and one was a man who had had heterosexual contact with prostitutes. Only one case was linked to transfusions of blood. Twenty-seven men and seven women were serologically tested for antibodies and all were HIV seroreactive. The most common causes of infection and the frequency of each were as follows: Pneumocystis carinii in 49 patients; cytomegalovirus in 43; Toxoplasma gondii in 30; Candida species in 24; Histoplasma capsulatum in 18; Mycobacterium species in 14; Cryptococcus species in eight; and Strongyloides stercoralis in six patients. Infection by Schistosoma mansoni (10 patients) was considered incidental because this trematode is endemic in Puerto Rico. The lung was the organ most frequently infected by a single microorganism: Pneumocystis carinii affected 49 patients. However, Cryptococcus species was the microorganism that infected more body systems: 20 different organs in eight patients. Nineteen patients had microglial nodular encephalitis, 86 patients had lymphocyte depletion in the spleen, and 58 had lymphocyte depletion in lymph node tissue. Twenty-seven men had testicular maturation arrest and variable germ cell loss. Three patients had malignant lymphoma, and two had Kaposi's sarcoma.(ABSTRACT TRUNCATED AT 250 WORDS)
