  • Title: Nocardiosis in HIV-positive patients: an autopsy study in West Africa.
    Author: Lucas SB, Hounnou A, Peacock C, Beaumel A, Kadio A, De Cock KM.
    Journal: Tuber Lung Dis; 1994 Aug; 75(4):301-7. PubMed ID: 7949078.
    Abstract:
    BACKGROUND: There are many reports of nocardiosis associated with HIV infection in industrialized and developing countries, but its true prevalence is unknown. MATERIALS AND METHODS: An autopsy study was performed of HIV-positive and HIV-negative patients dying on the general medical wards of a large hospital in Abidjan, Ivory Coast, in 1991. RESULTS: 247 HIV-positive adult cadavers were examined. 10 (4%) had nocardiosis of the lung, of whom 6 showed disseminated disease. 8 patients had one or more AIDS-defining pathologies, and 5 had nocardiosis as the main cause of death. Pulmonary tuberculosis was found in 87 cadavers (35%), giving a ratio of pulmonary nocardial to tuberculous disease of 1:9. No nocardiosis was seen in 42 HIV-negative cadavers. CONCLUSIONS: This is the highest recorded prevalence of HIV-associated nocardiosis in a representative sample. The prevalence of nocardiosis varies geographically, and in zones where HIV-associated tuberculosis is common, it is possible that some patients diagnosed as smear-negative pulmonary tuberculosis actually have nocardiosis. A revised strategy of sputum examination with gram stain is suggested to detect nocardia.
