Objectives: To determine the association between previous antituberculous treatment (anti-TB) and the development of drug resistance to antituberculous drugs in patients older than 18 years with a diagnosis of pulmonary tuberculosis (TB). Methods: Case and control study. The patients had a rapid sensitivity test and received anti-TB treatment at the Trébol Azul Health Post, Lima, Peru, between 2010 and 2015. The drug resistance was classified as Isoniazid Monoresistance or Rifampicin and Multidrug Resistance. The logistic regression model and odds ratio (OR) were used, with a 95% confidence interval (95% CI). Results: We evaluated 129 patients (58 cases and 71 controls). 44 (34%) of patients had previous anti-TB treatment. The prevalences of resistance to isoniazid, rifampicin and multidrug resistance were 12%, 4%, and 29%, respectively. In the multivariate analysis, patients with previous anti-TB treatment had a 14-fold greater risk of developing drug-resistance compared to those without prior treatment (adjusted OR 14.42, 95% CI 4.40-47.21, p <0.001). Conclusions: In this single-center study, the history of previous anti-TB treatment was associated with a 14-fold increased risk of drug resistance. No other potential risk factor defined a priori was associated with a greater risk of drug resistance.
