Pneumocystis carinii pneumonia. An uncommon cause of death in African patients with acquired immunodeficiency syndrome.

Admissions and deaths in a pulmonary medicine ward in Abidjan, Cote d'Ivoire, West Africa, were evaluated over a 6-month period in 1989 with systematic autopsies on all patients who died. Of 473 patients admitted, 38% were HIV-1 seropositive, 4% were HIV-2 seropositive, and 14% reacted to both viruses. A total of 100 patients (21%) died, and deaths were twice as frequent in HIV-seropositive compared with HIV-negative patients. The pathology of 78 autopsies showed that the predominant cause of death in HIV-seropositive patients was disseminated tuberculosis (40%). Cancer was the cause of death in 64% of HIV-negative patients. Pneumocystosis was found in only 9% of HIV-seropositive autopsies. Since Pneumocystis carinii is an uncommon cause of death in this population, prophylaxis for P. carinii pneumonia is not warranted for HIV-infected patients in Africa. In contrast, research on chemoprophylaxis for tuberculosis is urgently required.
