Immune thrombocytopenic purpura (ITP) is an autoimmune disease in which IgG-coated platelets are removed from circulation by the spleen, and platelet production is impaired due to increased thrombopoietin (TPO) clearance. Romiplostim, a novel TPO-mimetic agent, is approved for patients with ITP that are unresponsive to traditional treatments. However, there is little experience when using this drug before splenectomy. We describe herein the case of a young female with chronic ITP who was treated with romiplostim, underwent splenectomy shortly thereafter, and required plateletpheresis for postoperative rebound thrombocytosis with concomitant neurologic symptoms.
