ANCA-Associated Vasculitis
ANCA-associated vasculitis (AAV) is a rare autoimmune disease that causes swelling in small blood vessels. This swelling can reduce blood flow and damage organs like the kidneys, lungs, skin, and nerves. With early diagnosis and treatment, many people reach remission and get back to more of their daily life.
