- ANCA vasculitis is an autoimmune disease affecting small blood vessels in the body. It is caused by autoantibodies called ANCAs, or A nti- N eutrophilic C ytoplasmic A utoantibodies. ANCAs target and attack a certain kind of white blood cells called neutrophils. They target a part of neutrophils called the cytoplasm (the inside of the cell.)

ANCA-Associated vasculitides (AAV) are a group of rare, primary, systemic necrotizing small-vessel vasculitides. Granulomatosis with polyangiitis and microscopic polyangiitis account for ∼80-90% of all AAV. Exposure to silica dust, farming and chronic nasal Staphylococcus aureus carriage are associated with increased risk of developing AAV.
