Association of airway CCL28 with type 2 inflammation and secretory IgA in patients with asthma
Objective: This study aimed to investigate sputum CCL28 expression in patients with acute asthma exacerbations and its association with type 2 airway inflammation and secretory IgA. We further evaluated whether sputum CCL28, alone or in combination with routine clinical indicators, could assist in identifying eosinophilic asthma. Methods: This study included 75 patients with non-severe acute asthma and 27 healthy controls. Induced sputum samples were collected, and the levels of CCL28, IL-4, IL-...
