What is Henoch Schonlein Purpura (HSP)?
IgA vasculitis (IgAV), formerly and more commonly known as Henoch Schonlein Purpura (HSP), is an autoimmune disease that causes damage to blood vessels.
There is no known cause for HSP.
The main symptom of HSP is a characteristic rash called ‘purpura,’ which looks like small, raised purple spots or bruises most prominent on the lower half of the body.
In addition to the characteristic rash, HSP can also cause symptoms like:
- Abdominal pain
- Joint pain
- Blood in the urine- In rare cases, HSP can progress to serious kidney disease.
In extremely rare cases, HSP can also cause scrotal pain, neurologic symptoms, respiratory symptoms and eye disease.
HSP Diagnosis & Treatment
The diagnosis is made based on your provider’s physical exam. Skin biopsies of the rash can confirm the diagnosis but are almost never necessary.
There is no treatment for HSP. It usually gets better on its own. However, supportive care for your child includes:
- Plenty of rest and hydration
- Tylenol or ibuprofen for mild to moderate stomach and joint pain
- Urine test- all children diagnosed with HSP should have their urine tested for blood regularly for up to 6 months after the diagnosis is made
When Can My Child Return to School?
HSP is not contagious. Your child can return to school as soon as they are feeling well enough and don’t have a fever.
