Abstract
AIDS and tuberculosis (TB) are both endemic in Bujumbura, Burundi. An 11% failure rate to standard antituberculosis treatment (n = 173) was observed at the Tuberculosis Treatment Center of Bujumbura (CATB) in 1985-1986. All resistant cases (n = 19) were HIV seropositive. Among 328 consecutive cases with tuberculosis at the CATB during a 3 month period in 1986, 54.5% were HIV seropositive, which is five times higher than the prevalence in the general population in Bujumbura.
More female patients than male cases were HIV antibody positive (62 versus 49%, respectively; p < 0.02). Persistent weight loss, cough, and an anergic tuberculin test were more common in the HIV-seropositive group. Among 48 household members of HIV-seropositive patients with tuberculosis, 6 (12.5%) new cases of tuberculosis were identified, compared with none among 28 household members of HIV-seronegative patients with tuberculosis (odds ratio, 3.8; 95% confidence interval, 0.43-33.2).
HIV infection is a new risk factor for tuberculosis in Africa, and HIV-infected cases of tuberculosis may be more infectious than HIV-negative patients. The AIDS epidemic may drastically complicate the diagnosis, management, and control of tuberculosis in populations in which both infections are endemic.
