Resistant tuberculosis in children under 15 years of age, Colombia 2010-2015.

Introduction: Tuberculosis in children is a recent transmission reflection in the community. It is estimated that every year one million children get sick in the world because of this. In Colombia, 291 cases were notified in 2015. Objective: To update the information obtained from the surveillance activities of the drugresistance laboratory in children younger than 15 years of age in Colombia between 2010 and 2015. Materials and methods: This was a cross-sectional retrospective study. We studied the variables of origin, gender, age, type of tuberculosis, and HIV status in sensitive and resistant cases. We classified them according to their treatment background between new and previously treated to analyze their first and second line drug resistance profile. Results: From the notified cases, 16.4 % had a sensitivity test. 50.6 % were women, the pulmonary form was present in 70.6% cases, and 1.4 % presented with tuberculosis/HIV coinfection. We studied 565 cases, from which 503 (89.1 %) were new, presenting with multidrug-resistant tuberculosis, and a global resistance of 3.9 % and 9.5 %, respectively. From them, 62 had been previously treated (10.9 %), with 4.8 % and 19.3 % multidrug resistance and global resistance, respectively. There was no evidence of statistically significant differences during the studied years. Extremely resistant tuberculosis in new cases was 9.0 %. Conclusions: It is necessary for the Ministerio de Salud y Protección Social and the Instituto Nacional de Salud to promote the use of faster and more sensitive diagnostic tests such as the molecular ones recommended by the World Health Organization.
