Henoch-Schonlein purpura is not chronic, and serious complications are rare. There is risk of the purpura recurring when the individual resumes normal activity following the initial episode, but the rash is typically minor and other symptoms absent. Most children and adults diagnosed with HSP recover within several weeks with no long-term damage to their health. Those who experience complications of the gastrointestinal system or kidneys often receive a positive prognosis, assuming proper management of their condition. HSP is rarely fatal; death from renal failure occurs in just 1% of diagnoses.
