Worse sinonasal symptoms linked to higher risk of GPA relapse

Sinonasal symptoms, as assessed with 22-item Sinonasal Outcome Test (SNOT-22), a patient-reported questionnaire, are more severe when ANCA-associated vasculitis (AAV) is active than during remission, a study shows. Sinonasal symptoms are those that affect the nose and the sinuses, that is, the air-filled cavities around the eyes and nose.

DNA-targeting antibodies may be therapeutic options for AAV

Patrys’ PAT-DX1 and PAT-DX3, two DNA-targeting antibodies known as deoxymabs, can suppress production of the antimicrobial webs implicated in ANCA-associated vasculitis (AAV) without weakening other immune responses, according to preclinical work. These webs, called neutrophil extracellular traps (NETs), are made up of a scaffold of DNA and enzymes…

2 AAV types better suggest clinical features, outcomes in study

Having microscopic polyangiitis (MPA) or granulomatosis with polyangiitis (GPA) — the two most common types of ANCA-associated vasculitis (AAV) — better determines patients’ clinical features and outcomes than the type of AAV-driving, self-reactive antibodies they have. That’s according to a study in Spain that showed that GPA was an…

GTI may help ID who’s at risk for glucocorticoid side effects

ANCA-associated vasculitis (AAV) patients receiving a cumulative dose of at least 935 mg of glucocorticoids over six months are more likely to see clinically meaningful side effects, according to a study using calculations based on the Glucocorticoid Toxicity Index (GTI). The findings suggest the GTI, which considers the frequency…

Clinical trial recruitment for povetacicept ongoing in 3 countries

Recruitment is continuing in three countries for a Phase 1b/2a clinical trial testing Alpine Immune Sciences’ povetacicept in adults with autoimmune conditions affecting the kidneys, including ANCA-associated vasculitis (AAV). Called RUBY-3 (NCT05732402), the early study is designed to enroll an estimated 56 patients, ages 18 and older,…

Renal Risk Score a better predictor of long-term kidney function

The Renal Risk Score may be a better histopathologic classification model than Berden for predicting long-term loss of kidney function in people with ANCA-related vasculitis (AAV) who have glomerulonephritis, an inflammation of the kidneys’ filtering units, a study finds. Incorporating the renal risk score into clinical decision-making could help…

Tavneos can help older AAV patients recover from kidney failure

Tavneos (avacopan) improved kidney function and reduced the need for the glucocorticoid prednisone in four older patients who had signs of kidney failure due to ANCA-associated vasculitis (AAV), researchers in Canada report. While Tavneos may help patients enter into remission without the harmful side effects of glucocorticoids, “more…
