Pediatric bronchiectasis is common, but lung function tests do not accurately reflect bronchial damage severity. High-resolution CT scans reveal structural abnormalities, even with normal pulmonary function in children.

Area of Science:

  • Pediatric Pulmonology
  • Radiology
  • Clinical Medicine

Background:

  • Pediatric bronchiectasis is increasingly recognized as a significant clinical condition.
  • The correlation between pulmonary function and the severity of bronchiectasis in children remains a subject of ongoing research and debate.

Purpose of the Study:

  • To evaluate the extent and severity of bronchiectasis using high-resolution computed tomography (HRCT) scan scores.
  • To investigate the relationship between HRCT findings and clinical, microbiological, and pulmonary function data in pediatric patients.

Main Methods:

  • A cohort of 43 children diagnosed with bronchiectasis via HRCT was studied.
  • The Reiff score was employed to assess bronchiectasis extent, bronchial wall thickening, and bronchial wall dilatation.

  • Clinical, microbiological, and spirometry data were correlated with HRCT scores.

    • Main Results:

    • The most frequently affected lobes were the right lower lobe (65%), middle lobe (56%), and left lower lobe (51%).
    • No significant correlation was found between total HRCT scores (or subscores) and forced expiratory volume in 1 second (FEV1) or forced vital capacity (FVC).
    • Asthma was present in 74% of patients; early cough onset (<2 years) correlated with atopy, asthma, and positive microbiological findings.

    Conclusions:

    • Normal lung function can coexist with HRCT-identified bronchial structural damage in pediatric bronchiectasis.
    • Pulmonary function testing is not a reliable indicator for assessing the severity of lung disease in children with bronchiectasis.
