[Human immunodeficiency virus infection associated with tuberculosis]

In order to detect an association between HIV infection and tuberculosis (TB), 130 TB inpatients were studied one of whom presented a pulmonary disease due to Mycobacterium avium intracellulare. All had advanced TB, 95.4%, with pulmonary localization. Serum anti-HIV antibodies were detected by ELISA and their presence confirmed by immunoblotting in 4 (3.1%) individuals, three males and one female, with different degrees of pulmonary TB. Of the males, 1 was bisexual, 2 were promiscuous, and the female was the sexual partner of a non symptomatic HIV-infected man. No immunological disturbances or other AIDS related alterations were observed. There was one case of miliary TB, but neither atypical X-ray abnormalities nor extrapulmonary involvement were found. Tuberculin reaction was positive in three of the four HIV infected patients. Clinical, radiological and bacteriological evolution were favorable. Adverse drug reaction occurred in two cases, one of them presenting serious toxidermia caused by isoniazid. Of the 130 individuals, 12 presented risk factors for HIV infection so that the prevalence of anti-HIV antibodies presented here, 4 cases out of 12, is consistent with data from previous reports for high risk populations.
