Of the 788 eligible patients admitted during the study period, 100 (12.7%) had isolated EPTB, and 158 (20.1%) had both PTB and EPTB. Among 258 patients definitively included, 162 (62.8%) were men and the median age was 33 (25.75-44) years. Frequent extra-pulmonary locations of tuberculosis were lymph nodes (126 patients, 48.3%), pleura (121 patients, 46.4%) and peritoneum (25 patients, 9.6%). Using isolated pleural TB as a referent, independent determinants of isolated lymph node tuberculosis were HIV infection [odds ratio (95% CI), 2.58 (1.25-5.32)], duration of symptoms >6 weeks [2.41 (1.11-5.22)] and pulmonary involvement [2.39 (1.14-5.05)]. HIV infection [2.23 (1.06- 4.70)] and duration of symptoms >6 weeks [2.31 (1.08-4.96)] were also independent determinants of multifocal/disseminated tuberculosis.
Conclusion:
EPTB with or without concomitant PTB is frequent in this setting, with HIV infection being the main determinant.
