Adolescent tuberculosis: A challenge and opportunity to prevent community transmission

Abstract

Abstract Introduction Adolescents may present with adult-type pulmonary tuberculosis (TB), including cavity disease in upper lobes and smear-positive sputum, which involves a significant transmission risk for social and family contacts. Patients and methods A retrospective (2007–2012) observational study of a case series of TB was conducted in children and adolescents ( 12 years at diagnosis were compared. Results The series consisted of 124 patients (56.5% males, median age: 4.0 years). In half of the cases, the patient was of immigrant origin and TB was diagnosed after clinical–radiological suspicion, intra-thoracic disease being the most common (91.9%). Cultures yielded positive results in one third of cases (37.9%) and isolates were sensitive to oral first-line anti-TB agents in 100%. Median (interquartile range) duration of treatment was 6 (6–9) months, directly observed therapy was needed in 10 patients, and there was a satisfactory outcome after treatment in 98.4%. Among adolescents, TB was more prevalent in females (63.2%) and immigrant patients (68.4%), comorbidity at diagnosis and lung cavity forms were more common, and the source case was identified only in 21.1% of the patients. Conclusion Adult-type pulmonary TB is common among adolescents, may be associated with underlying medical conditions, and is often diagnosed late, posing a significant transmission risk to the community.
