Definition:

Henoch-Schonlein purpura is a disease that involves purple spots on the skin, joint pain, gastrointestinal problems, and glomerulonephritis (a type of kidney disorder).



Alternative Names:

Anaphylactoid purpura; Vascular purpura



Causes, incidence, and risk factors:

Henoch-Schonlein is caused by an abnormal response of the immune system. It is unclear why this occurs.

The syndrome is usually seen in children, but it may affect people of any age. It is more common in boys than in girls. Many people with Henoch-Schonlein purpura had an upper respiratory illness in the weeks before.



Symptoms:

Signs and tests:

The doctor will examine your body and look at your skin. The physical exam will reveal skin sores (lesions) and joint tenderness.

Tests may include:



Treatment:

There is no specific treatment. Most cases go away on their own without treatment. If symptoms persist, your doctor may recommend therapy with corticosteroids such as prednisone.



Support Groups:



Expectations (prognosis):

The disease usually gets better on its own without treatment.



Complications:
  • Bleeding inside the body
  • Kidney problems (in rare cases)

  • You develop symptoms of Henoch-Schonlein purpura, particularly if they last for more than a few days
  • You have low urine output after an episode of Henoch-Schonlein purpura
