Tuberculosis among AIDS patients in the United States, 1993

To evaluate the demographic characteristics, risk factors, and reported mortality of adults and adolescents with AIDS and tuberculosis (TB), we analyzed surveillance reports of persons with AIDS from state, territorial, and local health departments. Of 72,306 persons with AIDS diagnosed in 1993, 3,589 (5%) were reported with TB; of these, 2,782 (78%) with pulmonary TB, 552 (15%) with extrapulmonary TB, and 255 (7%) with both pulmonary and extrapulmonary TB were reported. In multivariate analysis, black [odds ratio (OR) 3.3, 95% confidence interval (CI) 2.9-3.7] and Hispanic (OR 2.5, 95% CI 2.2-2.9) persons had a higher risk of TB than white persons; injecting drug users (IDUs: OR 2.3, 95% CI 2.0-2.5) and persons exposed to HIV by heterosexual contact (OR 1.4, 95% CI 1.2-1.7) had a higher risk than men who have sex with men, and persons who were foreign born (OR 2.1, 95% CI 1.8-2.4) had a higher risk than those born in the United States. The highest proportions of AIDS patients with TB were in New York (11%), Illinois (7%), Florida (6%), Georgia (6%), and Texas (5%). The 1-year mortality rate among AIDS patients with pulmonary TB only (26%) and among those with extrapulmonary TB only (28%) was lower than among those with other AID-defining illnesses (38%) (p<0.001 and p<0.001, respectively). The high rate of TB among persons with AIDS, particularly in specific areas of the country and HIV exposure groups, emphasizes the need for continued support of strong TB control measures among persons infected with HIV.
