Evaluation of clinical and laboratory characteristics of childhood tuberculosis.

Abstract

Aim:Tuberculosis is one of the oldest and most contagious diseases of human history. One- quarter of the world’s population is infected with the tuberculosis bacillus. Childhood tuberculosis does not have a standard clinical and radiologic description. Herein, we aimed to evaluate the clinical, laboratory, and radiologic findings of childhood tuberculosis.Material and Methods:The medical records of 216 patients hospitalized and treated with a diagnosis of TB between January 2015 and July 2019 in the Division of Pediatric Infectious Diseases in our hospital, were examined retrospectively.Results:One hundred twenty-nine (59.7%) of 216 patients who were diagnosed as having TB were female and 87 (40.3%) were male. The age distribution of the patients was 12.3 (range, 0.33–18) years. One hundred sixty-nine patients (78.2%) had pulmonary, 34 (15.7%) had extrapulmonary, 13 had (6%) both pulmonary and extrapulmonary. One hundred forty-three (66.2%) patients had tuberculin skin test positivity. Acid-resistant bacteria were observed in 46 (21.3%) body fluid samples, and culture positivity was observed in 42 (19.4%) samples. The association of pulmonary tuberculosis and extrapulmonary tuberculosis was found with a higher rate in individuals who lived on minimum wage and in patients who had growth and developmental retardation (p=0.001, p<0.001). The hospitalization time was longer in these patients (p=0.027). The hemoglobin and sodium levels were significantly lower in patients who had extrapulmonary tuberculosis (p=0.044, p=0.002).Conclusion:Although the diagnosis of childhood tuberculosis is difficult due to the nonspecific signs and symptoms, it is a preventable and treatable disease.
