Self-healing of childhood immune thrombocytopenia usually takes about 6 weeks. Most children (about 80%) with childhood immune thrombocytopenia, i.e., childhood idiopathic thrombocytopenic purpura, have a history of viral infections (e.g., adenovirus, respiratory syncytial virus-induced acute upper respiratory tract infections, etc.) one to three weeks before the onset of the disease, and also after rubella, measles, chickenpox, and vaccinations. About 50% of children with childhood immune idiopathic thrombocytopenic purpura have their platelet counts gradually return to normal within 6 weeks. Children with severe disease need to be actively treated with glucocorticoids (dexamethasone, etc.), human immunoglobulin, and platelet transfusions to temporarily raise platelet counts if necessary, to prevent intracranial hemorrhage, gastrointestinal hemorrhage, and other serious bleeding complications. It is recommended that children should consult the hematology department in a timely manner, and individualized treatment plans should be formulated after assessment of the child’s condition by a specialist.
