Significance of PR3-ANCA positivity in eosinophilic granulomatosis with polyangiitis (Churg-Strauss)

Abstract

PR3-ANCA EGPA patients differ from those with MPO-ANCA and negative ANCA, and share clinical features with granulomatosis with polyangiitis. This suggests that PR3-ANCA EGPA could be a particular form of PR3-ANCA-associated vasculitis.
