We observed 34 tuberculosis in 470 patients infected by HIV (7,2 %). In 218 african there was 25 tuberculosis (19,5 %) but only 9 (2,6 %), all with SIDA, in 342 european and north african people. In 24 patients, tuberculosis was predominantly pulmonary and in 8 extra pulmonary or disseminated. Mycobacteria was isolated in 28 patients mainly from sputum and lymph nodes (only one resistant to INH). Standart drug regimens were effective in 76 %. 2 relapses were seen, 1 because inobservance, the other one year later during the course of SIDA. 8 patients (18 %) died from other opportunistic infections or terminal outcome of SIDA. Tuberculin skin test were positive in 18 (62 %) with median CD4 count = 260/mm3. In non tuberculous patients, only 15/436 had positive skin test, all of them with CD4 > 450/mm3.
