Henoch-Schonlein purpuraDefinitionHenoch-Schonlein purpura is a disease that involves purple spots on the skin, joint pain, gastrointestinal problems, and glomerulonephritis (a type of kidney disorder). Alternative NamesAnaphylactoid purpura; Vascular purpuraCausesHenoch-Schonlein is a type of hypersensitivity vasculitis and inflammatory response within the blood vessel. It is caused by an abnormal response of the immune system. It is unclear why this occurs. The syndrome is usually seen in children, but it may affect people of any age. It is more common in boys than in girls. Many people with Henoch-Schonlein purpura had an upper respiratory illness in the previous weeks. Symptoms
Exams and TestsThe doctor will examine your body and look at your skin. The physical exam will reveal skin lesions and joint tenderness. A urinalysis shows microscopic blood in the urine. A skin biopsy shows vasculitis. TreatmentThere is no specific treatment. Most cases go away on their own without treatment. If symptoms persist, your doctor may recommend therapy with corticosteroids such as prednisone. Outlook (Prognosis)The disease usually resolves spontaneously without treatment. Possible Complications
