Spring is the season of high incidence of allergic diseases, and children with allergic purpura appear clinically. Henoch-Schonlein purpura is a common capillary inflammation. Because capillaries are distributed all over the body, the disease can involve all organs of the whole body, and because renal capillaries are the most abundant, renal damage often occurs, which is also the seriousness of the disease.

Symptoms of allergic purpura: itchy skin with bleeding spots (purpura). Skin purpura is distributed on the extended surface of the skin, near the joints of limbs and buttocks, with symmetrical sides, higher than the skin, bright red at first, slightly gradual change, and may have abdominal pain, bloody stool and hematuria. In severe cases, it can recur and involve the kidney, which is called purpura nephritis.

The etiology of henoch-schonlein purpura is not clear, and there is no specific treatment at present. The treatment of allergic purpura is mainly the use of anti-allergic drugs. Children with henoch-schonlein purpura should avoid excessive activity. Adrenal cortical hormone can be used when the disease involves internal organs other than skin. Although Henoch-Schonlein purpura has a prolonged illness, most of them have a good prognosis, but the premise is to diagnose and treat as soon as possible.
