Efficacy and Safety of rhTPO and Eltrombopag in Patients With Primary Immune Thrombocytopenia (ITP)

Summary

Primary immune thrombocytopenia (ITP) is an acquired autoimmune hemorrhagic disease. In most cases, platelet count is negatively correlated with the severity of bleeding. Correcting low platelets is the main measure to prevent bleeding in patients with ITP. Both rhTPO and eltrombopag act on TPO receptors to increase platelets.Which one will have a better short-term (2 weeks) effect to improve platelets is the purpose of the investigator's research.
