Key Points about Henoch-Schonlein Purpura:
- Definition: Henoch-Schonlein Purpura is an IgA-mediated small vessel vasculitis that affects the skin, gastrointestinal tract, joints, and kidneys.
- Causes: HSP is often triggered by infections, particularly upper respiratory tract infections, though the exact cause is unknown.
- Symptoms: The classic tetrad of symptoms includes palpable purpura (typically on the lower extremities), abdominal pain, arthralgia or arthritis, and renal involvement (e.g., hematuria, proteinuria).
- Diagnosis: Diagnosis is primarily clinical, supported by blood and urine tests showing elevated IgA levels and kidney involvement. Skin or renal biopsy may be performed in atypical cases.
- Management: HSP is often self-limiting, but management includes supportive care such as analgesia for pain. Severe cases, especially those with renal involvement, may require corticosteroids or immunosuppressive therapy.
- Complications: Kidney involvement can progress to chronic glomerulonephritis or, rarely, end-stage renal disease (ESRD) in severe cases. Other complications may include gastrointestinal bleeding or intussusception.
