HSP, also known as IgA vasculitis, is characterized by inflammation of the small blood vessels located in the skin, joints, intestines, and kidneys, sometimes accompanied by bleeding. Adults are more severely affected than children. HSP typically clears up without treatment, but if it progresses to affecting the kidneys, medical help may be necessary.
There are two types of HSP. Henoch’s purpura, which involves skin spotting and abdominal issues, and Schölein’s purpura which affects skin and joints only.
