Question
How can allergic purpura be effectively treated?
Answer
Allergic purpura, also known as Henoch-Schönlein syndrome, is a common microvascular vasculitis-related hemorrhagic disease. The causes may include allergic reactions to infections, foods, drugs, pollen, and insect bites, but the exact cause is often difficult to determine. The disease is commonly found in children and adolescents, with symptoms primarily skin petechiae, particularly on the lower limbs, around joints, and buttocks. They appear in symmetrical arrangement, vary in size and color intensity, may merge into patches, and gradually fade over several months, but may recur. For the treatment of allergic purpura, the first step should be to prevent fever. Control and prevent infections; when infection or an infection focus is confirmed, sensitive antibiotics should be used for treatment, but excessive prophylactic use of antibiotics should be avoided.
