Abstract

Eosinophilic granulomatosis with polyangitis (EGPA) (formerly Churg-Strauss syndrome) is a rare small-sized vessel vasculitis belonging to the group of anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides. MPO-ANCA is present in only 31 to 38% of patients. In this review, we describe the pathophysiology of EGPA, which is characterized by a genetic predisposition, an environmental association, and a cellular dysfunction of eosinophils, neutrophils, and T and B cells.
