IBD diagnosis often comes before AAV, study finds

Inflammatory bowel disease (IBD) — a chronic disease where the bowel becomes inflamed, causing recurring lower abdominal pain and diarrhea — can overlap with ANCA-associated vasculitis (AAV) and is often diagnosed first, a study found. The finding suggests a possible link between the two diseases, and that having IBD…

Immune protein CX3CL1 may be biomarker of active MPA, GPA

High blood levels of the protein CX3CL1, a pro-inflammatory immune signal that appears to be associated with blood vessel inflammation, can accurately discriminate microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) patients with active disease from those without, a study found. Importantly, high CX3CL1 levels were found to increase the…

Argenx to stop clinical development of efgartigimod for AAV

Argenx has decided not to go ahead with its development plans for efgartigimod as a potential treatment for ANCA-associated vasculitis (AAV) after the therapy failed to show beneficial effects in late-stage clinical trials of two other autoimmune diseases. Efgartigimod is approved in the U.S. in two formulations for…

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…
