Two types of self-reactive antibodies, called anti-HMGB1 and anti-moesin antibodies, are present at significantly higher levels in the blood of ANCA-associated vasculitis (AAV) patients relative to healthy people and those with other autoimmune diseases, a study shows. The levels of these antibodies are also linked to how AAV manifested…

About 1 in 10 people with ANCA-associated vasculitis (AAV) failed to achieve complete remission at three months after starting induction treatment with rituximab, according to a small study in France. Poor responders were more likely to have symptoms in a specific area of the body — a localized form…

A new statistical model that considers age, disease type, patterns of organ involvement, and lab findings may help predict long-term survival in ANCA-associated vasculitis (AAV) better than available prognostic systems, a study suggests. The study “Development and internal validation of a model to predict long-term survival of ANCA…

Smoking at any time during one’s lifetime leads to more advanced disease and worse prognosis for people with ANCA-associated vasculitis (AAV), according to a 32-year study in Poland. Specifically, current or past smoking is linked to higher disease activity at diagnosis, and a greater need for kidney replacement and…

Despite high response rates to treatment strategies to reduce ear, nose, and throat involvement in ANCA-associated vasculitis (AAV), relapses are common, a review study reports. The study, “Systemic and Local Medical or Surgical Therapies for Ear, Nose and/or Throat Manifestations in ANCA-Associated Vasculitis: A Systematic Literature Review,” was…

Among the 56 reported cases of new or relapsed ANCA-associated vasculitis (AAV) after vaccination against SARS-CoV-2, more than three-quarters achieved remission with prompt treatment, according to a recent review study. SARS-COV-2 is the virus that causes COVID-19. AAV after vaccination may be related to several different mechanisms, including inflammation,…

Measuring neutrophil extracellular traps (NETs) — a type of antimicrobial web produced by immune neutrophil cells — induced by blood samples could be a useful way of monitoring the course of ANCA-associated vasculitis (AAV), a study shows. Compared with blood from people without the disease, blood from AAV patients…

Researchers have proposed a new cut-off value for blood levels of anti-neutrophil cytoplasmic antibodies (ANCAs) to improve the accuracy of ANCA-associated vasculitis (AAV) diagnosis. Using this cut-off value, researchers could accurately distinguish AAV from other diseases also characterized by inflammation and damage to small blood vessels. “This study provides a…

Argenx is planning to launch a proof-of-concept clinical trial later this year to test its therapy efgartigimod, approved to treat another autoimmune disease, in people with ANCA-associated vasculitis (AAV). Data from proof-of-concept studies can help companies and their researchers decide whether to develop a medicine for a specific…

May is Vasculitis Awareness Month and this year there are plenty of ways to get involved and raise awareness about the disease under the slogan “Navigating the unknown: You are not alone.” To help people stay engaged throughout the campaign, the Vasculitis Foundation has assembled an interactive calendar…
