%X <span style=\"font-family:Verdana;\">Microscopy-positive and drug-resistant pulmonary
tuberculosis (MPT+) is one of the most feared diseases due to the cost of its
management and the associated mortality. The GeneXpert, a new molecular test,
is in greater demand for the diagnosis of MPT+ resistance cases. The
application of GeneXpert to new cases of MPT+ is not effective in the country</span><span style=\"font-family:Verdana;\">¡¯</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\">s TB screening centres.
The objective of this study is to assess the contribution of GeneXpert to the
determination of MPT+ resistance cases in Bangui. The study was cross-sectional
and covered the period from February to July 2022. The diagnosis of
tuberculosis was first performed by microscopy with Ziehl Neelsen hot stain.
The GeneXpert was then used to test for resistance in the sputum of all
patients with positive microscopy. The collected data was entered into Excel
2013 and analysed with Epi Info 3.3.7. We analysed data from 755 patients, 80
of whom had resistance. The 80 patients ranged in age from 6 to 68 years (mean
age = 35 years). The prevalence of resistant TB was 10.60% (80/755). </span><span style=\"font-family:Verdana;\">Primary resistance accounted for 73.75% and
secondary resistance for 26</span><span style=\"font-family:Verdana;\">.25%. The age group 20 - 39 years (57.50%),
male (72.50%), 8th district (17.50%), people living in couples (53.75%),
farmers (13.75%) were the socio-demo</span><span style=\"font-family:Verdana;\">graphic
characteristics most affected by resistance. Treatment failure (13</span><span style=\"font-family:Verdana;\">.75%),
relapses (13.75%), the notion of contagion (28.75%), a history of smoking (40%)
and alcohol (61.25%) were the clinical antecedents reported by the patients.
Treatment failure and relapse were the variables associated with the occurrence
of resistant PMT+ (p </span></span><span style=\"font-family:Verdana;\">&lt;</span><span style=\"font-family:&quot;\"><span style=\"font-family:Verdana;\"> 0.05). A considerable proportion of the overall </span><i><span style=\"font-family:Verdana;\">Mycobacterium tuberculosis</span></i><span style=\"font-family:Verdana;\"> resistance to anti-tuberculosis drugs
(10.60%) was identified by GeneXpert. Treatment failure and relapse were the
factors associated with the risk of resistance.
