Résumé
Introduction: the aim of this study was to describe our experience with the use of GeneXpert and to evaluate its contribution to confirmation of the diagnosis of tuberculosis. Methods: descriptive, analytical and prospective study conducted from January 2013 to December 2013 Results: ninety-four patients underwent GeneXpert test for tuberculosis detection in patient in whom there is a clinical suspicion. GeneXpert was positive in 62% of cases. The radiological images which were highly suggestive of tuberculosis were associated with positive GeneXpert in 25% of cases. AFB was performed in 55 patients and was positive in 9 cases (16%) GeneXpert was positive in 46 sputum-negative (54%) and in 89% of sputum-positive The prevalence of extrapulmonary tuberculosis was 34%. The positivity rate was variable depending on the type of sample. Two cases with rifampicine resistance were detected. Conclusion: GeneXpert was a great contribution to the diagnosis of pulmonary and extrapulmonary tuberculosis but bacilloscopy remains essential.
