Abstract

To determine and to compare the incidences of active tuberculosis in HIV positive and HIV negative drug users and to describe the main characteristics of the tuberculosis cases. Prospective. Municipal Health Service, Amsterdam, the Netherlands. Data of the ongoing cohort study of HIV infection in Amsterdam drug users, including HIV serostatus and CD4 cell counts, from 1986 until 1996 were completed with data from the tuberculosis registration of the tuberculosis department of the Amsterdam Municipal Health Service and analysed statistically. Of 872 participants 24 persons developed culture confirmed tuberculosis during a total follow-up period of 4000 person years (py) (0.6 per 100 py). Nineteen persons were HIV positive (1.54 per 100 py) and 5 HIV negative (0.18 per 100 py). Multivariately, HIV infection and higher age increased the risk of tuberculosis substantially (relative risks 12.9; 95% confidence interval (CI): 3.4-48.8 and 6.8: 95% CI: 1.3-35.0 respectively). Thirteen of 22 pulmonary tuberculosis cases (59%) were detected by half-yearly X-ray screening of the chest. Tuberculosis occurred relatively early in the course of HIV infection at a mean CD4 cell number of 390/microliter. All but one patient completed the tuberc...Continue Reading
