Similar to neutrophils, circulating immune macrophage cells contribute to lung bleeding and damage caused by ANCA-associated vasculitis (AAV), a study showed. These circulating macrophages were found to have an abnormally activated DNA sensing system — typically used to detect foreign DNA and fight infections — that promotes inflammation. Deleting these macrophages…

A 16-year-old girl developed granulomatosis with polyangiitis (GPA), a type of anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV), after being infected with SARS-COV-2, the virus that causes COVID-19, according to a recent case report. Hers is the fourth known case of pediatric-onset AAV following COVID-19 infection, suggesting the virus could…
Tavneos (avacopan) will soon be available as an add-on treatment for adults in England, Wales, and Northern Ireland with severe, active granulomatosis polyangiitis (GPA) or microscopic polyangiitis (MPA), the two main types of ANCA vasculitis (AAV), following a decision by regulatory authorities. The National Institute for Health and…
Men with ANCA-associated vasculitis (AAV) have a 1.54 times higher risk of dying within one year than female patients, a new study finds. According to authors, “this [finding] may provide a reliable predictor for clinicians to judge the prognosis and select active treatment for patients with AAV.” The report,…
The number of ANCA-associated vasculitis (AAV) cases in Spain more than doubled between 2019 and 2021 following mass-scale vaccination against SARS-CoV-2, the virus that causes COVID-19, a new study found, suggesting the vaccine as a possible trigger. Researchers suspect the development of ANCA antibodies and AAV could be among…
After approximately $3.7 billion in acquisitions, Amgen will own the rights to Tavneos (avacopan), an approved oral therapy developed by ChemoCentryx to treat ANCA-associated vasculitis (AAV). Amgen is acquiring ChemoCentryx in a cash deal, expected to be completed by year’s end, the companies announced. “The acquisition of ChemoCentryx represents a…
An increase in ANCA antibodies may predict a relapse within six to 12 months in people with ANCA-associated vasculitis (AAV), according to a new study. The link between an antibody rise and AAV relapse was found to be significant in patients with myeloperoxidase (MPO)-ANCAs, or antibodies against…
A combination of lab tests commonly used to diagnose ANCA-associated vasculitis (AAV) may be able to accurately predict the long-term prognosis of patients and maybe select those needing more aggressive treatment, according to a 15-year study in China. The study, “Long-Term Prognostic Factors in Patients With Antineutrophil…
Similar to neutrophils, immune monocyte cells play an essential role in kidney damage caused by ANCA-associated vasculitis (AAV), a study discovered. The pro-inflammatory function of monocytes was stimulated by the immune signaling protein CSF2, also called GM-CSF. Therapeutically targeting monocytes or CSF2 may be a potential new treatment strategy…
A woman developed a rare case of acute kidney failure linked to ANCA-associated vasculitis (AAV) following her first dose of the Pfizer-BioNTech COVID-19 vaccine, according to a report. This case adds to previous reports suggesting that COVID-19 vaccines may, in rare instances, promote the development or exacerbation of autoimmune…
