Immune thrombocytopenia (ITP) is a disease with a heterogeneous clinical manifestation. In the majority of children newly diagnosed ITP is a self-limited benign disorder, while chronic ITP develops rarely. The clinical onset of ITP can occur in very different ways: from nearly invisible skin hemorrhage to severe life-threatening bleeding. Conventional treatments promote a response in most patients, but in a small number of children thrombocytopenia is unresponsive. In this article, we describe our experience of the clinical use of romiplostim in children with severe unresponsive newly diagnosed ITP. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology, and Immunology. The severity of bleeding decreased significantly after the start of romiplostim therapy in all cases. Durable complete (platelets > 100 × 109 /l) response was achieved in five out of six patients 4 to 8 weeks after starting therapy. Three children have remained in lasting remission for 1 to 3 years after the discontinuation of romiplostim. There were no adverse events associated with romiplostim.
