ObjectivesDrug resistant Mycobacterium tuberculosis causes much higher rates of treatment toxicity, failure or relapse, and mortality. We determined the drug resistant profile of Mycobacterium tuberculosis strains isolated from a population of HIV-infected patients in southern Brazil and studied the potential factors associated with resistance.MethodsWe conducted a retrospective cohort study to determine the resistance profile of Mycobacterium tuberculosis isolated from HIV-infected patients and factors that could be associated with resistance from 2000 to 2005.Results236 patients were included in the study. Resistance to at least one drug was observed in 32 (14.6%) isolates, and multi-drug resistance was observed in 4 (1.82%) isolates. On multivariate analysis, previous use of tuberculostatics and quinolones were related to any first-line drug resistance.ConclusionsIn our study, previous quinolone use was significantly associated to first-line anti-TB drugs resistance. Multi-drug-resistant tuberculosis (MDR-TB) is a major problem worldwide, and we believe quinolones should be used with caution in settings where TB is endemic.
