Anaphylactoid Purpura

Admission Information and Discharge Instructions

What is anaphylactoid purpura?

Anaphylactoid purpura is an inflammation of blood vessels. This inflammation can happen in any organ or blood vessel, but the rash caused by leaking blood vessels is easiest to see and feel on the skin. The official disease name is Henoch-Schoenlein purpura (HSP).

What is the cause?

The cause of this illness is not known, but there is a trigger in the body that causes inflammation (swelling) in the blood vessels. Triggers may include a recent cold, allergic reaction to medicines, insect bites, cold, chemicals, or certain foods.

It affects children age 3 to 17 years old. HSP is not an inherited disease. It is not contagious and cannot be prevented.
