Predictors of remission in children with newly diagnosed immune thrombocytopenia: Data from the Intercontinental Cooperative ITP Study Group Registry II participants.

Younger age, bleeding severity at diagnosis, and initial treatment with a combination of corticosteroids and IVIG are associated with remission at 12 months in the ICIS Registry II. Patients <1 year of age have the highest likelihood of remission. The relationship of bleeding and treatment at diagnosis requires further study to clarify whether these are independent predictors of remission.
