Acute thrombocytopenic purpura, a common disease in children, is also an autoimmune disease. Due to the disturbance of autoimmune balance, autoantibodies against platelets are produced, leading to excessive platelet destruction and the patient develops a series of bleeding symptoms. For acute thrombocytopenic purpura, if the patient has severe internal bleeding, platelet transfusion therapy can be considered to reduce the bleeding symptoms. The preferred method is also to take glucocorticoid therapy, which can be done with prednisone acetate, application of dexamethasone and so on, and also with recombinant human thrombopoietin. Also, the patient can be treated with intravenous gammaglobulin. Generally, after these treatments, the platelet count will gradually increase and the bleeding symptoms will gradually improve. In addition, acute thrombocytopenic purpura patients, the course of the disease generally presents short-term episodes, platelets rise, rarely recurrence of the disease.
