Progress on detection of exhaled nitric oxide in diagnosis and treatment of asthma in children / 国际儿科学杂志

ABSTRACT

Asthma is a common chronic airway inflammatory disease in children.In recent decades, the global prevalence of asthma in children has been increasing significantly.As a heterogeneous disease, asthma presents multiple phenotypes, with the type 2(eosinophilic)airway inflammation predominating in children.Currently, fractional exhaled nitric oxide(FeNO)is an internationally recognized marker of eosinophilic airway inflammation, and its value in the diagnosis and treatment of asthma in children has been gradually recognized.This article reviews the sources, detection methods, possible influencing factors of FeNO and its role in the diagnosis and treatment of asthma in children.
