Complement protein in urine may help predict AAV kidney flare

A protein fragment called Ba that’s produced when the alternative complement pathway is activated is found at high levels in the urine of people with ANCA-associated vasculitis (AAV) during a kidney flare, a small study suggests. This means it may serve as a biomarker for predicting and monitoring kidney-related…

I’ve had eosinophilic granulomatosis with polyangiitis (EGPA), a type of ANCA vasculitis, for 17 years. After my diagnosis, I had to change my life and reinvent myself. At the same time, I was grieving my life before EGPA and educating myself about my new normal.

AstraZeneca’s Fasenra (benralizumab) — approved for a rare type of asthma — does no worse than Nucala (mepolizumab) at keeping eosinophilic granulomatosis with polyangiitis (EGPA) in remission. These are the first findings of the head-to-head Phase 3 MANDARA clinical trial (NCT04157348) that showed the study met its…

Researchers in Korea have developed a new system to classify ANCA-associated vasculitis (AAV) into clusters, and provided an algorithm that can be used for such classification in future clinical studies. “This simple algorithm can incorporate any patient with atypical or nonspecific symptoms and can be easily modified to identify…

Subclinical changes are evident in the small blood vessels in the back of the eye and in the nails of people with ANCA-associated vasculitis (AAV) that are not associated with overt eye or nail symptoms, a study showed. Notably, a reduced blood vessel density in patients’ eyes, assessed via…

ANCA-associated vasculitis (AAV) patients with kidney disease have significantly more activity among six genes associated with forming neutrophil extracellular traps (NETs), a type of antimicrobial web produced by immune neutrophil cells, a study shows. The activity levels of these genes increases with kidney function decline and is tied to…

Two years of treatment with Nucala (mepolizumab) safely and effectively reduces signs and symptoms of hard-to-treat eosinophilic granulomatosis with polyangiitis (EGPA), the rarest form of ANCA-associated vasculitis. That’s according to a real-world study in Italy that also found similar outcomes with benralizumab, a therapy that works similarly to…

The prognostic immune nutritional index or PINI — a novel clinical tool based on counts of immune cells and levels of a blood protein called albumin — can be used to help predict the risk of death in people with ANCA-associated vasculitis (AAV), a new study shows. For serious…

Microscopic polyangiitis (MPA) was the most common type of ANCA-associated vasculitis (AAV) among girls and Hispanic children in a California tertiary care hospital, a small study has found. While time to diagnosis was shorter, children with the disorder seemed to need more intensive care and dialysis, a treatment that…

A rare case of two family members with granulomatosis with polyangiitis (GPA), a type of ANCA-associated vasculitis (AAV), highlights the potential genetic underpinnings of the autoimmune disease, according to a recent report. This case of a mother and son both presenting with GPA add to a small, but accumulating,…
