Pediatric allergic purpura

Allergic purpura in children is also called hemorrhagic capillary poisoning or Henoch-Schouml; nlein syndrome. This is a more common type of capillary allergic disease. The lesions most commonly involve the skin, followed by the gastrointestinal tract, joints, and kidneys. The onset is more rapid and the symptoms are variable. Occurs in children over 3 years of age, especially in school-age children, the incidence of men is about 2 times that of women. The history of upper respiratory tract infections is often 1 to 3 weeks before the onset of disease, more than in spring and autumn. In addition to involving the kidneys, it responds better to hormones and other treatments. The course of disease is mostly about 1 month, with occasional prolongation, but the recurrence rate is high. About 30% of patients have a tendency to relapse.
