Myeloperoxidase–Antineutrophil Cytoplasmic Antibody (ANCA)–Positive and ANCA-Negative Patients With Granulomatosis With Polyangiitis (Wegener's): Distinct Patient Subsets
Antibodies, Antineutrophil Cytoplasmic
Granulomatosis with Polyangiitis
We were unable to demonstrate important clinical differences between MPO-ANCA-positive and PR3-ANCA-positive patients with GPA. The risk of relapse was associated more closely with disease type than with ANCA type in this patient cohort. These findings deserve consideration in the assessment of relapse risk in patients with AAV.
