HSP (Henoch-Schönlein purpura)
Possible complications
HSP will usually get better on its own without causing any further problems, but occasionally it can lead to potentially serious complications.
The main complications associated with HSP are problems affecting the kidneys, which may not occur until several weeks or months after the other symptoms have passed. This can cause:
- blood in your urine
- protein in your urine you won't be able to see this yourself, but it can sometimes cause your urine to become "frothy"
- high blood pressure (hypertension)
- swelling (oedema) , particularly around the eyes and ankles
These symptoms eventually get better in most people, but in a small proportion the kidneys can stop working properly (kidney failure).
HSP can also sometimes cause other problems, such as swelling and pain in the testicles (orchitis) or an abnormal folding in the gut (intussusception) that can lead to a blockage in your bowel.
