A Population-based Study Showing Better Renal Prognosis for Proteinase 3 Antineutrophil Cytoplasmic Antibody (ANCA)-associated Nephritis Versus Myeloperoxidase ANCA-associated Nephritis.
Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is usually differentiated based on clinical phenotypes, but recent data indicate that myeloperoxidase (MPO)-AAV is genetically distinct from proteinase 3 (PR3)-AAV. We reviewed a population-based cohort of AAV, focusing on differences in clinical and laboratory characteristics and to compare renal outcome between MPO-ANCA and P
