BACKGROUND: Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA) are distinct forms of antineutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV). Increasing evidence suggests overlapping features, particularly in proteinase 3 (PR3)-ANCA-positive EGPA and GPA with eosinophilia. This study aimed to characterize overlapping EGPA/GPA forms and assess their...
