Henoch-Schonlein purpura (HSP), now more commonly called IgA vasculitis, is a condition that often appears suddenly with a striking rash of reddish-purple spots on the skin. While it can look alarming, especially on the legs, the good news is that many cases resolve on their own with supportive care. However, careful monitoring is essential because HSP can sometimes affect the kidneys, joints, and digestive system.
In this article, we’ll break down what HSP is, what to expect, and how to manage it both medically and at home.
What Is Henoch-Schonlein Purpura?
HSP is a type of small blood vessel inflammation (vasculitis). It occurs when the immune system deposits a protein called IgA into the walls of tiny blood vessels, causing them to swell and leak. This leads to the telltale rash as well as potential involvement of other organs.
The condition is most common in children between the ages of 3 and 15 but can also occur in adults, where it often runs a more severe course.
