Despite many efforts of prevention and the availability of free treatment, TB/HIV co-infection is still rampant in Guinea. The objective of this study was to describe the epidemiology of smear positive pulmonary tuberculosis according to HIV status among patients hospitalized in the infectious diseases department of Conakry University Hospital. This was a descriptive and analytical retrospective study of patient records admitted for pulmonary tuberculosis from January 2003 to December 2012. During this period, 1953 cases of tuberculosis were collected of which 346 (17.7%) were smear positive. There was a marked male predominance (59.7%). The average age was 38 ± 11 years. The majority of patients originated from the suburbs of Conakry and its surrounding prefectures (76.7%). People without profession were most represented (40.7%). A level of primary education was the most frequently reported (39.7%). Out of 325 patients tested for HIV, the serology was positive in 185 patients (56.9%). A contact with a TB patient was reported in 21.4% of HIV negative patients, and in 6.5% of the HIV-positive group (p = 0.0006). There was no difference between the two groups regarding clinical signs and symptoms. The mean CD4 count was comparable in both groups (p = 0.05). Lethality was higher among co-infected patients (30.4% against 15.56%; p = 0.00037). Strengthening the prevention of TB among PLWHA by the administration of isoniazide seems necessary and warrants further study on this subject in Guinea.
