IgA vasculitis (also called Henoch–Schönlein purpura) is a type of small-vessel vasculitis, meaning it causes inflammation in the body’s tiny blood vessels. It often affects the skin, joints, intestines, and kidneys. The condition is more common in children but can also occur in adults. A key feature is the buildup of IgA antibodies in blood vessel walls, which leads to symptoms such as purpura (a raised purple skin rash), joint pain, abdominal pain, and sometimes blood or protein in the urine. Most cases in children resolve on their own, but adults and those with kidney involvement may need treatment. IgA vasculitis is considered part of the CHCC 2012 classification of primary vasculitis.
