Soluble IL-7R alpha in blood seen as possible biomarker of AAV activity

Higher blood levels of soluble interleukin 7 receptor subunit alpha (sIL-7R alpha) — a portion of a receptor protein involved in inflammation — significantly associate with lower disease activity in people with ANCA-associated vasculitis (AAV), a small study found. These preliminary findings suggest that the soluble receptor protein “can…

Tavneos superior to steroids at reversing severe kidney disease

Tavneos (avacopan) effectively reverses severe kidney disease associated with ANCA-associated vasculitis (AAV) compared with standard steroid therapy, according to a subgroup analysis of the Phase 3 ADVOCATE clinical trial. Greater improvements in kidney function with Tavneos were sustained for the two months of follow-up after the treatment stopped.

Tavneos approved in Australia as add-on therapy for GPA, MPA

Tavneos (avacopan) has been approved in Australia as an add-on oral therapy for adults with two main types of ANCA-associated vasculitis (AAV): microscopic polyangiitis (MPA) and granulomatosis polyangiitis (GPA). The approval from Australia’s Therapeutic Goods Administration specifically covers the use of Tavneos in combination with rituximab or…

EGPA generally more severe in patients with GI involvement

Rates of relapse, and mortality, are higher in people with eosinophilic granulomatosis with polyangiitis (EGPA) that affects the gastrointestinal (GI) tract — and periods of remission less likely — relative to EGPA patients without GI involvement, according to a study in China. Those with GI involvement also presented with…

Preventive Antibiotics in AAV May Reduce Risk of Severe Infections

Preventive, or prophylactic treatment with certain antibiotics can reduce the risk of severe infections for people with ANCA-associated vasculitis (AAV) who are receiving immunosuppressive treatment, a new analysis shows. Specifically, good results were found in a clinical trial with a combination of antibiotics known as TMP/SMX. “This … is…

Triple Therapy Effective in AAV Relapse After Kidney Transplant

A combination of rituximab, prednisone, and tacrolimus effectively treated a recurrence of anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) after a kidney transplant, a case study reported. The case highlights the importance of closely monitoring AAV patients on immunosuppressive therapy with belatacept, particularly when a kidney injury follows a kidney…

Immune Cells in Urine Could Help to Assess AAV Kidney Damage

Measuring the number of immune T-cells in urine could be used to help identify kidney damage in people with ANCA-associated vasculitis (AAV), a new study suggests. These urinary T-cells also may aid in predicting treatment responses and the risk of future disease relapse. “Their promising potential as noninvasive…

Blood Markers May Help Distinguish Lung Infection From AAV Flares

Higher blood levels of the molecule pro-calcitonin (PCT) are a marker of lung infection among ANCA-associated vasculitis (AAV) patients with lung disease, a new study reports. Combining PCT with other blood markers can further increase the accuracy of identifying infection, and may be useful for distinguishing between AAV-related lung…
