ESTIGARRIBIA, Gladys et al. Surveillance of drug resistance of Mycobacterium tuberculosis in Paraguay, 2014 to 2017. An. Fac. Cienc. Méd. (Asunción) [online]. 2022, vol.55, n.3, pp.27-34. ISSN 1816-8949.

The objective of the study was to identify the resistance of Mycobacterium tuberculosis to drugs in Paraguay, 2014 to 2017. A retrospective observational study was carried out. The data from the National Tuberculosis Program of Paraguay between the years 2014 to 2017 were used. All patients with a diagnosis of Tuberculosis who underwent a resistance test were included. Data were extracted in Excel and analyzed with Stata 17.0. 3429 tuberculosis patients who had a result of at least one sensitivity test were included. Resistance was found in 2.1% of patients. Resistance to Rifampicin was present in 0.3% of cases while to Izionazide in 0.6% of cases. The prevalence of resistance was higher in men 3.4 (95% CI 2.2 - 4.8) p = 0.003, who resided in the Chaco 6.0 (95% CI 3.4 - 9.7) p = 0.000, previously treated 2.7 (95% CI 1.1 - 5.1) p = 0.010. In the model, it was observed that a previously treated patient has a greater chance of having resistance OR 2.62 (95% CI 1.1 - 6.24). The prevalence of resistance of Mycobacterium tuberculosis to drugs was related to having been previously treated.
