Abstract:
Non-cystic fibrosis bronchiectasis(referred to as bronchiectasis)is a common chronic airway disease.Neutrophils have traditionally been considered to play a dominant role in the airway inflammation of bronchiectasis.However,it has been discovered that approximately 20%to 30%of bronchiectasis patients exhibited elevated eosinophil counts(Sputum eosinophil ratio>3%or blood eosinophil count>300/μl)in their sputum and blood samples,referred to as eosinophilic bronchiectasis(EB).Based on this novel discovery of the inflammatory phenotype,some scholars have advocated treating bronchiectasis as an"inflammatory disease"rather than an"infectious disease"in a novel therapeutic approach.This article reviews the discovery and the latest research advancements of EB,exploring its pathophysiological basis,clinical characteristics,and treatment,with the aim to facilitate the understanding and management of EB.
