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…
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…
People with ANCA-associated vasculitis (AAV) who develop low antibody levels associated with rituximab treatment are at high risk of serious infections, a new study from France highlights. “Our real-life study provides useful information to answer a practical question: what is the risk of [serious infection] when initiating or…
A combination of two standardized scores of kidney damage can accurately predict the prognosis of renal disease in people with ANCA-associated vasculitis (AAV), a study indicates. This composite measure — the renal risk score (RRS) and the renal vascular lesions (RVL) score — “may serve as a new predictor…
A new statistical model that considers age, disease type, patterns of organ involvement, and lab findings may help predict long-term survival in ANCA-associated vasculitis (AAV) better than available prognostic systems, a study suggests. The study “Development and internal validation of a model to predict long-term survival of ANCA…
Different types of disease-driving antibodies tend to associate with different symptoms of eosinophilic granulomatosis with polyangiitis (EGPA), the rarest form of ANCA-associated vasculitis. That’s according to the study “Spectrum of ANCA-specificities in eosinophilic granulomatosis with polyangiitis. A retrospective multicenter study,” published in Clinical and Experimental Rheumatology.
Women carrying a genetic mutation dubbed rs9274619 have a significantly higher risk of ANCA-associated vasculitis (AAV) associated with antibodies against myeloperoxidase (MPO) than men, a new study shows. Among MPO-AAV patients, this mutation was linked to a greater likelihood of eye involvement and a lower risk of lung involvement.
Physicians in the U.S. are excited about the potential of Tavneos (avacopan), an approved treatment for people with ANCA-associated vasculitis (AAV), to reduce the use of corticosteroids, a type of steroid medication, in this patient population. That enthusiasm is due to the safety concerns associated with the long-term…
Many people with ANCA-associated vasculitis (AAV) have profound fatigue that’s severe enough to fulfill the diagnostic criteria for chronic fatigue syndrome, even when the disease isn’t active, a study shows. “We emphasize that physicians should be aware of this when assessing treatment and management strategies for improving quality…
