Introduction: Multidrug-resistant tuberculosis treatment is effective in 50% of patients due to several factors including antibiotic susceptibility of the microorganism, adverse treatment reactions, social factors, and associated comorbidities.Objectives: In this study, we describe the demographics, clinical characteristics, and factors associated with treatment outcomes in multidrug-resistant tuberculosis (MDR-TB) patients in Medellín, Colombia.Materials and methods: We conducted a retrospective analysis using data from patients diagnosed with MDR-TB attending Hospital La María in Medellín, Colombia, for treatment between 2010 and 2015. Patients were categorized as having successful (cured) or poor (failure, lost to follow-up, and death) treatment outcomes. Associations between demographic, clinical factors, laboratory results, treatment outcomes, and follow-up information were evaluated by univariate, multivariate, and multiple correspondence analyses.Results: Of the 128 patients with MDR-TB, 77 (60%) had successful outcomes. Of those with poor outcomes, 26 were lost to follow-up, 15 died, and 10 were treatment failures. Irregular treatment, the presence of comorbidities, and positive cultures after more than two months of treatment were associated with poor outcomes compared to successful ones (p<0.05 for all). The multiple correspondence analyses grouped patients who were lost to follow-up, had HIV, and drug addiction, as well as patients with treatment failure, irregular treatment, and chronic obstructive pulmonary disease.Conclusion: The recognition of factors affecting treatment is essential and was associated with treatment outcomes in this series of patients. Early identification of these factors should increase the rates of treatment success and contribute to MDR-TB control.
La aparición de Mycobacterium tuberculosis multirresistente constituye un serio problema para el control de la tuberculosis, por lo que se ha considerado que la resección quirúrgica del tejido pulmonar afectado, junto con el tratamiento médico adecuado, podría proporcionar la curación en algunos pacientes con tuberculosis pulmonar multiresistente. En este estudio de tipo descriptivo, retrospectivo, se evaluaron los resultados clínicos y bacteriológicos de la resección quirúrgica en un grupo seleccionado de pacientes con tuberculosis pulmonar multirresistente. Se revisaron las historias clínicas del Hospital La María de Medellín de 1990 a 2000, y se encontró que se habían sometido a cirugía 73 pacientes con diagnóstico de tuberculosis durante este periodo, 28 de los cuales tenían como indicación quirúrgica tuberculosis multirresistente (resistencia a isoniacida y rifampicina), 21 de los cuales habían recibido tratamiento prequirúrgico. En 14 (50%) se había practicado lobectomía superior y en 10 (36,7%), neumonectomía. Todos recibieron tratamiento posquirúrgico por un periodo promedio de 12,5 meses. En 88,9% (25/27) de los casos, la baciloscopia fue negativa después de 6 semanas de la cirugía y hasta finalizar el tratamiento antituberculoso; 6 pacientes presentaron nuevamente baciloscopia positiva, aunque 4 tuvieron baciloscopia negativa después de un nuevo esquema de tratamiento. Los pacientes, de acuerdo con las normas del ministerio, fueron seguidos con baciloscopia mensual y no con cultivo como es lo indicado en los casos de multirresistencia. La cirugía junto con el tratamiento médico adecuado constituye una buena alternativa de curación para algunos pacientes con tuberculosis pulmonar multirresistente.
