[The study of the nitric oxide monitoring in airway allergic diseases]

Summary Airway allergic disease is a chronic noninfectious airway disease characterized by allergic airway inflammation and hyperresponsiveness. In recent years, the incidence of allergic diseases has increased year by year, and the pathogenesis is complex and not clear, which seriously affected the quality of life of patients and has become a global health problem that needs to be solved urgently. In recent years, scholars at home and abroad believe that the concentration of nitric oxide (NO) in oral and nasal exhaled can be used as an objective indicator to reflect the severity of upper and lower airway inflammation, and is a novel biomarker for noninvasive airway inflammation. This article reviews the clinical application of NO monitoring in allergic diseases and its research progress.
