Benefits and risks of bronchoalveolar lavage in severe asthma in children.

Background: Although bronchoscopy can be part of the exploration of severe asthma in children, the benefit of bronchoalveolar lavage (BAL) is unknown. The present study aimed to decipher whether systematic BAL during a flexible bronchoscopy procedure could better specify the characteristics of severe asthma and improve asthma management.

Material And Methods: The study took place in two departments of a university hospital in Paris.
