Correct Answer: 40-60%
Description: Henoch-Schonlein purpura(HSP) is an acute, systemic, immune complex-mediated, leukocytoclastic vasculitis. It is characterized by a triad of palpable purpura (without thrombocytopenia), abdominal pain, and ahritis. Most patients have an antecedent upper respiratory illness. More than 90 percent of Henoch-Schonlein purpura cases occur in children younger than 10 years; however, adults with this condition are more likely to experience complications than children. All patients with Henoch-Schonlein purpura develop a purpuric rash, 75 percent develop ahritis, 60 to 65 percent develop abdominal pain, and 40 to 50 percent develop renal disease. www.aafp.org
