Blood tests that look for the anti-neutrophil cytoplasmic autoantibodies (ANCAs) that cause ANCA-associated vasculitis (AAV) may help identify patients with kidney involvement, a study shows. Still, ANCA testing was not as accurate for this purpose as a kidney biopsy, wherein a small piece of kidney tissue is collected…

The production of new B-cells, a type of immune cell that helps fight infections but is also involved in the abnormal immune attacks that drive ANCA-associated vasculitis (AAV), is dysfunctional in people with the autoimmune disease, a study found. The findings could help shed light on the biological underpinnings…

Symptoms and disease manifestations of eosinophilic granulomatosis with polyangiitis (EGPA), a rare type of ANCA-associated vasculitis (AAV), are generally similar between patients with and without ANCAs, the self-reactive antibodies that drive most AAV cases. That’s according to a study analyzing data from a registry of people with vasculitis, or…

Rituximab is superior to other immunosuppressive treatments at preventing post-surgery relapse in granulomatosis with polyangiitis (GPA) patients undergoing surgery to address subglottic stenosis, a common complication that causes airway narrowing. That’s according to a study that analyzed data from 25 GPA patients who were followed for more than…

People with the rarest type of ANCA-associated vasculitis (AAV), called eosinophilic granulomatosis with polyangiitis (EGPA), and AAV patients with reduced kidney function are more likely to experience thrombosis (blood clots that disrupt blood flow), according to a single-center study in China. Results also indicated AAV patients with higher…

Biomarkers measured in blood or urine may help track disease activity and organ damage in people with ANCA-associated vasculitis (AAV), according to a systematic review study. AAV is an autoimmune disorder in which self-reactive antibodies called anti-neutrophil cytoplasmic antibodies (ANCAs) attack the body’s own neutrophils — a type of…

About half of people with granulomatosis with polyangiitis (GPA) have impairment of a valve in the heart, a study from Poland indicates. This heart valve dysfunction doesn’t cause notable problems for most patients, but a handful may have more severe complications that can require…

At ANCA Vasculitis News, we have spent the last year bringing you coverage of the latest developments in research and treatment for ANCA-associated vasculitis (AAV). Here, we’ve compiled a list of the top 10 most-read articles of 2023, with a brief description of each. We look forward to…

Self-reactive anti-neutrophil cytoplasmic antibodies, or ANCAs, may play a unique role in driving blood vessel inflammation in people with eosinophilic granulomatosis with polyangiitis (EGPA), the rarest form of ANCA-associated vasculitis (AAV). That’s according to a small study, which found that disease relapses outside the respiratory system occurred only in EGPA…

In a Phase 3 trial of Tavneos (avacopan) in people with ANCA-associated vasculitis (AAV), the therapy’s effectiveness in the subgroup of patients on standard induction treatment with rituximab was similar to that of the overall study population. Reasonable safety also was seen, and sustained one-year remission was higher…
