Progress of the etiology of bronchiectasis in children / 国际儿科学杂志

ABSTRACT

Bronchiectasis is a chronic lung disease involving a "vicious circle" of complex interactions between host,respiratory pathogens,and environmental factors.With the wide application of high-resolution CT,the diagnostic rate of bronchiectasis has been improved and the etiology and pathology of bronchiectasis have been promoted.After infection,cystic fibrosis,primary immunodeficiency disease,bronchial foreign body and primary ciliary dyskinesia are the main causes of bronchiectasis,and the clinical manifestations of bronchiectasis in children are not specific.HRCT examination should be conducted as early as possible for children suspected of bronchiectasis,and the potential etiology should be actively sought for children.This paper summarizes the recent progress of the etiology of bronchiectasis in children,and provides the clinical data for the correct understanding of the etiology of bronchiectasis.
