Extrapulmonary tuberculosis in children under the age of 15 hospitalized at the Pereira Rossell Hospital Center, Uruguay

Abstract

Background: Tuberculosis is a public health problem. Children constitute a population at risk of becoming ill and evolving into serious forms. Aim: To describe the frequency, epidemiological, clinical and evolutionary characteristics of children under 15 years of age hospitalized for extrapulmonary tuberculosis (EPTB) at the Pereira Rossell Hospital-Uruguay, during 2009-2019. Methods: Descriptive, retrospective study, review of medical records and records of the Honorary Commission for the Fight Against Tuberculosis. Variables: age, sex, epidemiological and clinical link, diagnostic confirmation, treatment and complications. Results: 77 cases of EPTB were registered, 45 (58%) were hospitalized in this center. Average age 7 years, males 25 (56%). All received the Bacillus Calmette-Guérin vaccine. An epidemiological link was identified in 28 (62%). The forms of EPTB were: pleural 26 (58%), central nervous system CNS 9 (20%), lymphoganglionic 4 (9%), cutaneous 2 (5%), bone 1 (2%), peritoneal 1 (2%), pleural- peritoneal 1 (2%), bone-CNS 1 (2%). Etiology was confirmed in 23 (51%): by culture 16, GeneXpert 5, by both 2. Thirty six (80%) patients completed treatment. Four (9%) presented complications: convulsive state 2, cerebral hemorrhage 1, multiple organ failure 1. Conclusions: EPTB occurred in previously healthy children. The diagnosis requires a high index of suspicion and the confirmation of the simultaneous use of several diagnostic techniques.
