ABSTRACT
PURPOSE: This is a pilot study that describes the feasibility and clinical course of a cohort of preschool children with severe asthma undergoing a combined adenotonillectomy (TA), bronchoscopy (B), and bronchoalveolar lavage (BAL) procedure.
METHODS: A retrospective cohort study of preschool patients with severe asthma who underwent a combined TA-B-BAL procedure between 2012 and 2019. Subjects were treated at a tertiary care asthma clinic and had a diagnosis of preschool asthma according to the Canadian Thoracic Society Guidelines. Data on demographics, clinical characteristics, medication use, virology and microbiology from bronchoalveolar lavage, and asthma control questionnaires were collected. Variables were analyzed using paired t test.
RESULTS: Eighteen preschool subjects (mean age 3.19 ± 1.13 years) with severe asthma were identified through the asthma clinic. Patients treated with standard asthma care and a combined TA-B-BAL procedure experienced a decrease in the number of oral steroid courses (p = 0.017), emergency department visits (p = 0.03) and wheezing exacerbations (p = 0.026) following the procedure. Ten patients experienced clinically meaningful improvements in TRACK scores after the procedure (p < 0.001).
CONCLUSION: This pilot study provides early evidence that a combined TA-B-BAL procedure is feasible in preschool children with severe asthma and that the procedure may reduce asthma medication use and hospital visits.
