Rituximab treatment more effective than cyclophosphamide for GPA

Treatment with rituximab is superior to cyclophosphamide at inducing disease remission in people with granulomatosis with polyangiitis (GPA), according to a single-center study in Iran. While the safety profiles of the two therapies were comparable, treatment with rituximab was more effective, the study found. Specifically, about 90% of…

AI model identifies AAV subgroups that better predict outcomes

Using data from the largest ANCA-associated vasculitis (AAV) patient database compiled to date, researchers identified five new subgroups that predict patient outcomes better than classifying patients according to granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), two AAV subtypes. The new disease clusters, identified with advanced artificial intelligence (AI)…

Antibiotic mix may prevent serious infections with rituximab for GPA

The combination antibiotic trimethoprim-sulfamethoxazole (TMP-SMX) may help prevent serious infections for people with granulomatosis with polyangiitis (GPA) who are taking the immunosuppressant rituximab, a study of U.S. data shows. Preventive treatment, or prophylaxis, with TMP-SMX in people with this common type of ANCA-associated vasculitis (AAV) tended to…

1 in 4 patients may relapse on rituximab maintenance, study finds

About a quarter of people with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) under maintenance treatment with rituximab experience relapses, mainly during the first two years. That’s according to a real-world study in Greece that looked at data from 101 people with GPA or MPA, the two most common…

Conduit to move AZD1656 into clinical trials for AAV, lupus

Conduit Pharmaceuticals is planning to launch Phase 2a clinical trials to test its lead oral candidate AZD1656 in people with immune system disorders — specifically ANCA-associated vasculitis (AAV) as one indication. “With its potential to become a first-in-class therapy for autoimmune diseases, AZD1656 represents a significant leap forward…

ANCA blood tests may help detect kidney involvement: Study

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…

Set of clinical red flags identified as checklist for possible EGPA

Researchers have identified a set of clinical red flags that could help detect eosinophilic granulomatosis with polyangiitis (EGPA), the rarest type of ANCA-associated vasculitis (AAV). Among the red flags are specific high-level thresholds of eosinophils, a type of immune cell, combined with other signs including asthma, nasal polyps,…

1 in 10 ANCA-positive people with lung disease develop AAV

About 1 in 10 people with idiopathic interstitial pneumonia (IIP), a condition marked by lung scarring of an unknown cause, who test positive for antineutrophil cytoplasmic antibodies, or ANCAs, eventually develop ANCA-associated vasculitis (AAV), a study shows. These patients’ risk factors for AAV include testing positive for ANCAs against…
