Henoch-Schonlein purpura, also known as IgA vasculitis, is a condition characterized by inflammation in the small blood vessels of the skin, gastrointestinal tract, and kidneys. Its symptoms often include a distinct purplish rash primarily found on the lower legs and buttocks, as well as joint pain. In some cases, it can lead to abdominal discomfort and inflammation in the joints. Although rare, severe kidney damage can occur as a complication of this condition.
While Henoch-Schonlein purpura can affect individuals of any age, it is most commonly observed in children under the age of 10. Fortunately, the condition typically improves without intervention. However, if the kidneys are affected, medical attention is necessary.

Henoch-Schonlein purpura (HSP) is a condition where small blood vessels in the body become inflamed, leading to bleeding in the skin, abdomen, and kidneys. The exact cause of this initial inflammation is unclear but may involve an inappropriate immune system response to various triggers. About half of HSP cases are preceded by upper respiratory infections like the common cold, while other triggers include chickenpox, strep throat, measles, hepatitis, certain medications, food, insect bites, and exposure to cold weather. Similarly, the cause of IgA vasculitis (IgAV), another term for HSP, is currently unknown. It often occurs after infections of the throat or respiratory system, primarily strep throat, and may involve an unusual immune system reaction to the infection, whether caused by bacteria or a virus.
