N2 - Introduction: Pediatric noncystic fibrosis (CF) bronchiectasis has a variety of causes. An early and accurate diagnosis may prevent disease progression and complications. Current diagnostics and yield regarding etiology are evaluated in a pediatric cohort at a tertiary referral center. Methods: Available data, including high-resolution computed tomography (HRCT) characteristics, microbiological testing, and immunological screening of all children diagnosed with non-CF bronchiectasis between 2003 and 2017, were evaluated. Results: In 91% of patients [n = 69; median age 9 (3-18 years)] etiology was established in the diagnostic process. Postinfection (29%) and immunodeficiency (29%) were most common, followed by congenital anomalies (10%), aspiration (7%), asthma (6%), and primary ciliary dyskinesia (1%). HRCT predominantly showed bilateral involvement in immunodeficient patients (85%) and those with idiopathic bronchiectasis (83%). Congenital malformations (71%) were associated with unilateral disease. Completion of the diagnostic process often led to a change of treatment as started after initial diagnosis. Conclusion: Using a comprehensive diagnostic protocol, the etiology of pediatric non-CF bronchiectasis was established in more than 90% of patients. HRCT provides additional diagnostic information as it points to either a more systemic or a more localized etiology. Adequate diagnostics and data analysis allow treatment to be specifically adapted to prevent disease progression.
