New statistical model predicts AAV prognosis with good accuracy

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…

EGPA symptoms differ by patients’ antibody type, study suggests

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.

AAV genetic risk factors may differ according to sex: Study

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.

Most AAV patients have fatigue severe enough to be a disorder

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…
