Henoch-Schonlein purpura

In medicine, Henoch-Schonlein purpura is vasculitis and immune complex disease that is "systemic non-thrombocytopenic purpura caused by hypersensitivity vasculitis and deposition of IGA-containing immune complexes within the blood vessels throughout the body, including those in the kidney (kidney glomerulus). Clinical symptoms include urticaria; erythema; arthritis; gastrointestinal hemorrhage; and renal involvement. Most cases are seen in children after acute upper respiratory infections."

Henoch-Schonlein purpura may be associated with bacteremia from staphylococcus aureus.
