What is Henoch-Schonlein purpura (HSP)?
Henoch-Schonlein purpura (HSP) is a form of blood vessel inflammation or vasculitis. There are many different conditions that feature vasculitis. Each of the forms of vasculitis tends to involve certain characteristic blood vessels. HSP affects the small vessels called capillaries in the skin and frequently the kidneys. HSP results in a purplish skin rash (most prominent over the buttocks and behind the lower extremities) associated with joint inflammation (arthritis) and sometimes cramping pain in the abdomen. Henoch-Schonlein purpura is also referred to as anaphylactoid purpura.
What causes HSP?
HSP occurs most often in the spring season and frequently follows an infection of the throat or breathing passages. HSP seems to represent an unusual reaction of the body's immune system that is in response to this infection (either bacteria or virus). Aside from infection, drugs can also trigger the condition. HSP occurs most commonly in children, but people of all age groups can be affected, including adults.
