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…

Treatment with rituximab helps most adults, ages 75 and older, with ANCA-associated vasculitis (AAV) achieve and maintain disease remission, a French study found. However, a higher rate of serious infections and deaths were reported when rituximab was used as an induction therapy, in combination with high doses of glucocorticoids,…

Excess of a particular amino acid, or protein building block, in the blood may make neutrophils — a type of white blood cell that first responds to an infection or injury — more reactive in ANCA-associated vasculitis (AAV) and large-vessel vasculitis, a study has found. The amino acid, called…

The Johnson & Johnson COVID-19 vaccine may have triggered kidney inflammation associated with ANCA-associated vasculitis (AAV) in a 52-year-old woman, according to a recent case report. “We believe that this is the first case report of AAV that occurred following adenovirus vector COVID-19 vaccine administration,” its scientists wrote. “Increasing…

Measuring the blood levels of a protein called BAFF could help predict the chances of remission after induction treatment with rituximab in people with ANCA vasculitis (AAV), according to a new study. Determining the BAFF levels in the blood also could guide further care for AAV patients, the researchers…
