[Opportunistic parasitic diseases and mycoses in AIDS. Their frequencies in Brazzaville (Congo)].

To determine the frequency of opportunistic parasitic and mycotic diseases in adult AIDS patients in the Congo, a study was conducted at l'Hôpital Universitaire de Brazzaville in 1986 and 1987. Diagnosis of AIDS was made using the WHO clinical definition for Africa (Bangui, 1985) and HIV seropositivity Pasteur Elisa test. Oral pharyngeal candidiasis occurred in 36% of cases. Intestinal parasitic profile found in 118 patients, 2/3 of whom were associated with chronic diarrhoea showed clearly relative frequency of isosporiasis (Isospora belli): 9.3% and rarity of crystosporidiosis: 4.2%. 12 meningitic cryptococcosis cases out of 139 patients was confirmed (8.6%); for cerebral toxoplasmosis, it was by comparing the serum toxoplasmosis antibody and cerebrospinal fluid rates on 75 patients that an estimation of 20% was reached. Pneumocytis carinii pneumonia seems to be rare, lower than 10%. No case of disseminated histoplasmosis and malignant strongyloidiasis was observed.
