Faulty Immune System Component in AAV Leads to Neutrophil Activation, Kidney Damage, Study Shows

A faulty immune system component in patients with active ANCA-associated vasculitis (AAV) is not equipped to stop ANCA-induced neutrophil activation, leading to kidney damage, a Chinese study shows. The component is called complement factor H. The study, titled “Complement Factor H Inhibits Anti-Neutrophil Cytoplasmic Autoantibody-Induced Neutrophil Activation by…

AAV Patients in Japan on Low Daily Prednisone Doses as Maintenance Therapy Seen as More Likely to Relapse

Low daily doses of oral prednisone — 2.5 mg/day or less — during long-term remission maintenance therapy was associated with a higher rate of relapse in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in Japan, a study reports. The study, “Risk Factors for Relapse of Antineutrophil Cytoplasmic Antibody-associated Vasculitis in…

Adding Azathioprine to Glucocorticoid Regimen Doesn’t Improve SNV Remission Rates, Study Finds

The addition of azathioprine, an immunosuppressant, to a glucocorticoid treatment regimen does not improve remission rates for patients with non-severe systemic necrotizing vasculitides (SNVs), a new study shows. The study, “Adding Azathioprine to Remission-Induction Glucocorticoids for Eosinophilic Granulomatosis With Polyangiitis (Churg-Strauss), Microscopic Polyangiitis, or Polyarteritis Nodosa Without…

Patients with AAV Caused by Thyroid Medicine Have Better Remission Rates After Treatment Stopped

The thyroid medication propylthiouracil (PTU) can sometimes cause antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), but a new study shows the condition has a milder course and excellent remission rates after ending PTU treatment. The study, titled “Clinical characteristics and outcomes of propylthiouracil-induced antineutrophil cytoplasmic antibody-associated vasculitis…
