AI Summary
The article discusses the potential use of sputum eosinophil peroxidase as a biomarker for eosinophilic asthma. Eosinophilic asthma is a subtype of asthma characterized by high levels of eosinophils in the airways, leading to inflammation and breathing difficulties. By measuring the levels of eosinophil peroxidase in sputum samples, researchers aim to identify patients with eosinophilic asthma and tailor appropriate treatments more effectively. This biomarker could help improve asthma management and reduce the risk of exacerbations.
