Childhood immune thrombocytopenia may recur, but most children can be completely cured. Most children with childhood immune thrombocytopenia have a history of viral infection before the onset of the disease, but the exact cause of the disease is not completely clear, and it may be due to the immune response that occurs after the invasion of viruses and other pathogens into the body. Most of the children with this disease can recover spontaneously, and about 80% of the children can gradually return to normal platelet counts within 6 weeks, but a small number of children may still have relapses. Children with childhood immune thrombocytopenia vary in their condition, and those with severe disease are at high risk of serious bleeding complications such as intracranial hemorrhage and gastrointestinal hemorrhage, and require aggressive treatment with glucocorticosteroids (prednisone, dexamethasone, etc.), human immunoglobulin, and other medications. If the platelet count is lower than 20*10^9/L or there are obvious bleeding manifestations (black stools, bloody stools, hematuria, etc.), the platelet count should be elevated by transfusion of homogeneous single platelet suspension to prevent serious bleeding that may be life-threatening. It is recommended that the child should visit the Department of Hematology in a timely manner, and an individualized treatment plan should be developed according to his/her condition. After the disease is cured, children should have regular blood tests to monitor their platelet counts dynamically, so that they can be detected as early as possible and receive timely treatment when the disease recurs.
