ANCAs may hold unique role in vessel inflammation with EGPA

Self-reactive anti-neutrophil cytoplasmic antibodies, or ANCAs, may play a unique role in driving blood vessel inflammation in people with eosinophilic granulomatosis with polyangiitis (EGPA), the rarest form of ANCA-associated vasculitis (AAV). That’s according to a small study, which found that disease relapses outside the respiratory system occurred only in EGPA…

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…
