Whether children can be cured of purpura depends on the type and severity of purpura. Most of the children can be cured through early diagnosis and regular treatment. The main clinical categories of children purpura are thrombocytopenic purpura and allergic purpura, mechanical purpura. 1, thrombocytopenic purpura: also known as autoimmune thrombocytopenic purpura, is a common disease of children’s blood system. It is usually seen in children who were physically fit in the past. It is caused by viral infection, insect bite, allergic reaction or vaccination after the body produces its own platelet antibodies to destroy platelets, resulting in platelet reduction and thus symptoms such as bleeding from skin mucosa. When the platelets are above 20×10^9/L and there is no obvious bleeding tendency, no treatment can be given, and most children can remit naturally in about 1 year. In about 20% of children, there is a possibility of evolving into chronic thrombocytopenic purpura, which is relatively difficult to treat and should be seen in hospital in time. If there is a significant increase in purpura and recurrent nasal bleeding, treatment must be carried out under the guidance of a doctor, usually using glucocorticoids, gammaglobulin and, if necessary, platelet thrombopoietin (TPO) or TPO receptor agonist for treatment, which can achieve certain efficacy; 2. Allergic purpura: Allergic purpura in children includes simple skin type purpura, joint type purpura, abdominal type purpura, renal The most common type of allergic purpura is a leukocyte fragmentation vasculitis involving small blood vessels. Clinical manifestations include palpable purpura of the skin, joint pain, renal involvement, abdominal colic and intestinal bleeding, with cutaneous purpura as the main diagnostic criterion. Symptoms tend to resolve spontaneously within 2 months, but recur in nearly 30% of children. The treatment plan should be decided according to the severity of the disease and the involvement of organs. The simple type of allergic purpura is mostly self-limiting and can resolve on its own in 1-2 weeks without treatment. If the kidney is seriously damaged, leading to renal failure, or gastrointestinal bleeding, obstruction, can endanger the life of children, treatment is more difficult, need long-term follow-up; 3, mechanical purpura: usually due to the pressure rise in small blood vessels, leading to its rupture and bleeding to form purpura, seen in violent crying, vomiting, etc., usually can be self-receding, no special treatment.
