The frequency of ANCA-associated vasculitis (AAV) among the Indigenous peoples of Alaska is high compared with other populations worldwide, especially the granulomatosis with polyangiitis (GPA) form of the disease,  a study reports. Native Alaskans and American Indians in Alaska with AAV also may have more severe clinical features at…

Lower blood levels of glutathione peroxidase-3 (GPX-3), an antioxidant enzyme, are significantly associated with greater disease activity and blood vessel damage in people with ANCA-associated vasculitis (AAV), a study found. “We demonstrated that [blood] GPX-3 concentration at diagnosis has the potential to be a novel biomarker that can assess…

Long-term treatment with Nucala (mepolizumab) reduces disease activity and helps to prevent progressive organ damage in people with eosinophilic granulomatosis with polyangiitis (EGPA), the rarest type of ANCA-associated vasculitis (AAV), data from a real-world study show. Finding among patients in Spain also showed that most using Nucala were able…

Among ANCA-associated vasculitis (AAV) patients with kidney failure and waiting for a kidney transplant, undergoing the transplant reduces their risk of dying by more than half relative to continuing on dialysis, a replacement therapy. These findings, from a 20-year study of people in France with AAV listed for a…

Researchers in Japan have identified four distinct subtypes of microscopic polyangiitis, or MPA — a type of ANCA-associated vasculitis (AAV) — that are associated with different clinical characteristics, which may help in better predicting, and improving, patient outcomes, according to the team. One subtype was marked mainly by kidney…

People with ANCA-associated vasculitis (AAV) patients whoo have low blood levels of sulfatides, a type of fatty molecule, are significantly more likely to have future kidney failure, a single-center study in South Korea indicates. The predictive potential of blood sulfatide levels was independent of direct associations with kidney involvement…

A key sign of heart disease — calcium buildup in the blood vessels that supply the heart, known as coronary artery calcification — was found in a majority of adults with ANCA-associated vasculitis (AAV) in a study by U.S. researchers. Such calcium deposits are associated with atherosclerosis, or the…

Eosinophilic granulomatosis with polyangiitis (EGPA) patients treated at private practices in the U.S. have high disease burden associated with multiple symptoms and simultaneous health conditions, a study showed, mirroring findings reported for patients treated at academic settings. Patients treated in private practice demonstrated variable responses to standard treatments, with some patients…

Machine learning based on clinicians’ notes found in electronic health records accurately identifies cases of ANCA-associated vasculitis (AAV), a study demonstrated. The model was found to be superior to traditional algorithms based on diagnostic codes with or without medication use at identifying AAV cases. “Its application to EHR [electronic…

A graphic prediction tool may accurately estimate the chance of survival over two years in people ANCA-associated vasculitis (AAV), according to a study at a single Chinese hospital. The tool, a nomogram based on 16 predictive factors, was able to differentiate patients who survived from those who didn’t with…
