EA patients must have \\>300 eosinophils\u002FmcL, EGPA requires asthma + eosinophilia + other specific features, and HES requires high eosinophil counts (\\>1500 cells\u002FmL).\n\nMethods: Data will be analyzed using Mann-Whitney U, ANOVA, and Spearman correlation tests, with results presented as mean ± SEM.\n\nThis study will help explore eosinophil behavior in eosinophilic diseases and evaluate mepolizumab's effects on these cells.",[47,48,49],"Eosinophilic Asthma","Eosinophilic Granulomatosis With Polyangiitis (EGPA)","Hypereosinophilic Syndrome (HES)",[51,16,19,13,52,53,54,55,56,57],"Eosinophils","Eosinophilic asthma","Eosinophil subpopulations","Flowcytometry","Biomarker","Asthma severity","EGPA severity","NOT_YET_RECRUITING","2025-03-27",{"date":61,"type":62},"2025-04-04","ACTUAL",{"date":64,"type":43},"2025-04",{"date":66,"type":43},"2026-12",{"name":5,"class":6}]
