Henoch Schonlein Purpura (HSP)

The medical term for inflammation of the blood vessels is "vasculitis", which means they get irritated and swollen. This inflammation can cause the small surface blood vessels to bleed into the skin, which results in the rash commonly seen in Henoch-Schnlein purpura (HSP). It can also affect blood vessels in the bowel and the kidneys.

HSP usually gets better without treatment and is not usually serious.

HSP typically causes:
  • a skin rash (purpura) that looks like small bruises or reddish-purple spots, usually on the buttocks, around the elbows and on the legs, and sometimes also on the face and upper body
  • pain in the joints such as the knees and ankles, which also become swollen, tender and warm
  • tummy pain, which tends to come on after the rash has developed but can occur beforehand
It can also result in:
  • small amounts of bleeding in the intestines and the kidneys blood may be seen when your child passes stools or urine
  • flu-like symptoms such as fever, nausea and vomiting
