What this Trial Is About
The study subjects of this research are patients with eosinophil-associated pulmonary diseases, including eosinophilic granulomatosis with polyangiitis, idiopathic hypereosinophilic syndrome, idiopathic acute eosinophilic pneumonia, idiopathic chronic eosinophilic pneumonia, and primary simple pulmonary eosinophilia. The aim is to detect eosinophil subtypes in peripheral blood based on surface protein expression, to understand the differences in eosinophil subtypes among patients with different diseases, to elucidate the significance of different eosinophil subtypes, and ultimately to provide a theoretical basis for the selection of treatment directions for patients.
