Role of Neutrophilic Inflammation in Severe Asthma in Children / 实用儿科临床杂志

ABSTRACT

Asthma was considered to be a kind of chronic airway inflammatory diseases mediated by eosinophils(EOS),mast cells,T lymphocytes for a long time,and the typical pathologic features of asthma was airway EOS inflammation.The current study had found out that elevated neutrophils in airway were seen in severe asthma,and this kind of asthma had a poor response to corticosteroids.Impaired neutrophil chemotaxis and apoptosis of airway neutrophilia may be associated with persistent neutrophilic inflammation in the airways of severe asthma.A deep research into the mechanisms of neutrophilic phenotypes asthma would contribute to the new strategy of therapy.This article discusses a range of topics related to the role of neutrophilic inflammation in severe asthma in children,which were organizedas follows.
