Pulmonary tuberculosis in a Pediatric Reference Hospital in Bogotá, Colombia.

Abstract

In Colombia, epidemiological and clinical information related to pediatric tuberculosis (TB) is scarce. Data are needed to define the impact of the disease and to strengthen measures for detection and treatment. It is proposed to analyze the pediatric population diagnosed with pulmonary TB in a national reference institution. Retrospective observational study including pediatric patients with pulmonary and miliary TB, and pulmonary and extrapulmonary involvement, treated between January 1, 2008 and December 31, 2016. A descriptive analysis of the selected variables was done. A total of 93 cases of diagnosed TB were identified, of which 61 cases were classified as pulmonary (65.6%). The location of TB occurred only in lungs in 51 patients (83.6%), was miliar in 3 (4.9%), pulmonary and extrapulmonary involvement in 7 patients (11.5%). The mean age was 7.5 years (0.5-18 years). Clinical criteria used for diagnosis was related to 98.3% of the cases, whereas radiological criteria in 90.2%. Bacteriological criterion was met in 42.6% of the cases. The most frequent symptoms were coughing (83.6%), fever (63.9%), and weight loss (26.2%); human immunodeficiency virus co-infection occurred in 3 cases (4.9%). During treatment, 5 mortality cases were recorded, although they were not attributable to TB. The epidemiological characterization of pediatric patients with pulmonary TB helps to achieve a better diagnostic approach in this population. Improving monitoring and follow-up activities in children with pulmonary TB, as well as promoting actions for adequate prevention and treatment is highly necessary.
