Silent zone detection in asthma and its relation to T2 inflammation

Abstract

Abstract Objective Study objectives are to detect small airways disease in asthma and to study T2 inflammatory markers (eosinophil count, IgE, phenotyping) in association with small airways disease. Methods and patients The retrospective study at OPC at Al Qassimi Hospital of EHS included 83 patients with confirmed asthma diagnosis. Based on their ACT scores, patients were divided into two groups. An assessment of demographic data, blood eosinophils, fractional exhaled nitric oxide, IgE, PFE25-75, FEV1%, R5-20, X5 and AX was carried out. Analyzing and collecting data. Results In this study, a significant correlation was found between the R5-20, X5, and AX values of the small airway and the asthma control test. Uncontrolled asthmatics had a higher fractional exhaled nitric oxide level and blood eosinophilic count. Conclusion In asthma management, small airways clinical impact should be investigated actively. Impulse oscillometry is an excellent marker for asthma control.
