Introduction: Tuberculosis (TB) in children is increasingly becoming an important cause of global child morbidity and mortality. Objective: The objective of this study was to evaluate the clinical spectrum of TB in children under the age of 15 years and document any changes that occur over time. Materials & Methods: This observational study was conducted in the pediatric outpatient department (OPD) of 250 Bedded TB Hospital, Shyamoli, Dhaka, from October’2016 to January’2017. A total 71 children of both sex up to 15 years of age, who were diagnosed as having TB and attended the pediatric OPD of TB hospital during the four months study period were enrolled. The data was analyzed on the basis of patient’s age, gender, socioeconomic status, mode of presentation, BCG vaccination status, history of contact with smear positive TB patient, clinical findings, investigations and associated co-morbidities. Results: This study revealed that among the 71 cases of TB, (72%) had extra-pulmonary TB (EPTB) and (28%) had pulmonary TB (PTB), the commonest age group was 6 to 15 years with male preponderance (51%). Pulmonary TB was diagnosed mostly clinically (60%) followed by positive sputum smear result (20%), gastric aspirate for acid-fast bacilli AFB (5%) and sputum for Gene Xpert (5%). Distribution of extra-pulmonary TB (EPTB) according to the organ involvement was TB lymphadenitis (49%), osteoarticular TB (19.6%) and abdominal TB (5.9%). Cervical lymphadenopathy was the commonest presentation (76%) among the EPTB cases. Tuberculin skin test (TST) was positive in (69%) cases. Among the total cases (90%) children had TB alone whereas (10%) had other co-morbid disease along with TB. Conclusion: Extra-pulmonary TB (EPTB) was more prevalent among the childhood TB cases in a tertiary level set up where cervical TB lymphadenitis was the commonest.
