IgA Vasculitis (Henoch-Schönlein Purpura)

• IgA/Henoch-Schönlein purpura (HSP), also known as anaphylactoid purpura, is a form of vasculitis that affects the small arterial vessels, mostly common in the skin, gastrointestinal tract and the kidneys.
• In about 50% of children the disease follows an upper respiratory infection.
• Many organisms and allergens have been suggested to trigger HSP including bacteria, viruses, medications, food, and vaccinations.  
• The disease may be a result of an abnormal activation of the immune system in response to one of those triggers.  HSP occurs throughout the year, but some studies have shown that there is an increase in cases during the fall and winter months.
