RESUMEN
Introducción: La tuberculosis persiste como un importante problema de salud mundial. En el 2016 se estimaron 600 000 casos de resistente a rifampicina, y entre estos 490 000 casos multidrogorresistentes. Objetivo: Describir el comportamiento de la resistencia de los aislados de M. tuberculosis de pacientes con tuberculosis pulmonar notificados en Cuba entre los años 2015-2017. Métodos: Se determinó la susceptibilidad a isoniacida y rifampicina mediante el método de la nitratasa. A los aislados resistentes a rifampicina/multidrogorresistentes se les determinó mediante el método proporcional la susceptibilidad a ofloxacina, kanamicina, amikacina y capreomicina. Resultados: El 93,2 por ciento de los aislados fueron sensibles a isoniacida y rifampicina. En 39 se identificó resistencia a isoniacida y 23 fueron resistente a rifampicina. Se identificaron 10 multidrogorresistentes. No se detectó resistencia a fármacos de segunda línea. Conclusiones: Los resultados alertan sobre la necesidad de investigar las causas que han conllevado al incremento de la tuberculosis resistente en Cuba(AU)
Introduction: Tuberculosis continues to be an important health problem worldwide. In the year 2016, as many as 600 000 cases of rifampicin resistance were estimated, among which 490 000 were multi-drug resistant. Objective: Describe the behavior of resistance to M. tuberculosis isolates in patients with pulmonary tuberculosis reported in Cuba in the period 2015-2017. Methods: Susceptibility to isoniazid and rifampicin was determined by the nitratase method. Susceptibility of rifampicin resistant / multi-drug resistant isolates to ofloxacin, kanamycin, amikacin and capreomycin was determined by the proportional method. Results: Of the isolates analyzed, 93.2 percent were sensitive to isoniazid and rifampicin. Isoniazid resistance was identified in 39 and 23 were rifampicin resistant. Ten multi-drug resistant isolates were identified. Resistance to second line drugs was not detected. Conclusions: Results warn about the need to study the factors leading to the increase in resistant tuberculosis in Cuba(AU)
