The diagnosis of eosinophilic granulomatosis with polyangiitis has been ‘masked’ by asthma: a case report

If asthma symptoms persist despite intensive corticosteroid treatment or the eosinophil count exceeds 5%, consider the possibility of EGPA. The presence of ANCA exerts a substantial impact on the prognostic outcomes in EGPA. ANCA-negative patients typically exhibit reduced survival rates, primarily attributed to a higher incidence of cardiac involvement. Nevertheless, advancements in early diagnosis and therapeutic interventions have led to improved survival rates, even in cases complicated by cardiac and pulmonary manifestations.
