4A44.92/D69.0 IgA vasculitis



IgA vasculitis (also known as Henoch-Schonlein purpura) is an autoimmune condition characterized by inflammation of the small blood vessels. It is caused by an immune response to certain antigens, and is typically seen in children and young adults.


IgA vasculitis is usually diagnosed based on a physical examination, medical history, and laboratory tests that measure levels of immunoglobulin A (IgA) in the blood. Other tests may include imaging studies and skin biopsy.

Differential diagnosis

Differential diagnoses for IgA vasculitis include other autoimmune conditions such as lupus, rheumatoid arthritis, and systemic vasculitis.


Treatment of IgA vasculitis typically involves medications such as corticosteroids, immunosuppressants, and anti-inflammatory drugs. Physical therapy and lifestyle changes may also be recommended.


The prognosis for IgA vasculitis is generally good, as most people recover fully with appropriate treatment. However, some people may experience long-term complications such as joint pain, skin discoloration, and kidney problems.
