Blood marker for inflammation may predict AAV disease activity

A blood marker, called C-reactive protein to albumin ratio (CAR), may predict and help monitor disease activity in people with ANCA-associated vasculitis (AAV), according to a small study in Turkey. This is important in clinical practice because “close monitoring, early recognition, and timely treatment of disease activity may limit…

Antibodies against HMGB1 and moesin may be useful biomarkers

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…

New statistical model predicts AAV prognosis with good accuracy

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…

Ear, nose, throat symptom relapses common in AAV, despite treatment

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…

AAV may emerge in rare cases after COVID-19 vaccination: Study

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,…

New ANCA cut-off value may aid accuracy of AAV diagnosis

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…

Proof-of-concept efgartigimod trial for AAV expected this year

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…
