The protein myeloperoxidase (MPO) may increase the activation of neutrophils — key immune cells in ANCA-associated vasculitis — and heighten vascular injury in patients, a new study shows. The study, “Myeloperoxidase influences the complement regulatory activity of complement factor H,” was published in the journal Rheumatology. ANCA-associated vasculitis (AAV)…

A new case study supports previous findings that hydralazine — a medication used to treat high blood pressure — may cause ANCA-associated vasculitis with severe kidney injury, leading its researchers to recommend its use “generally be avoided.” A separate case report, published in March, linked this medication to end-stage kidney disease…

The National Organization for Rare Disorders (NORD) will celebrate the 35th anniversary of both the 1983 Orphan Drug Act and NORD’s founding at a dinner tonight in Washington, D.C. The 2018 Rare Impact Awards, to be held at the Andrew W. Mellon Auditorium, will be webcast via Facebook for those…

The levels of certain immune molecules called cytokines in the blood are better at identifying the types of specific autoantibodies present in ANCA-associated vasculitis (AAV) patients than at determining clinical diagnosis, a recent study shows. Based on this finding, researchers suggest that AAV patients should be classified by autoantibody type…

Patients with ANCA-associated vasculitis (AAV) who receive Rituxan (rituximab) infusions for maintaining sustained remission fare better in the long term than those receiving the immunosuppressant azathioprine, according to French researchers. Fewer patients who received Rituxan as remission-maintenance therapy experienced a relapse during a 60-month (five-year) follow-up. Researchers found that survival…
