Prospective Study of Patients With Thrombocytopenia Following HSCT

Summary

Isolated thrombocytopenia is a common and severe complication of HSCT, which often leads to an increased risk of life-threatening hemorrhage, frequent requirement of platelet transfusions and extended hospital stays, representing a challenging clinical problem. Current treatments for thrombocytopenia after HSCT are frequently unsatisfactory in platelet recovery and for preventing potentially fatal bleeding complications. Therefore, it is urgent to explore an effective therapy to improve the outcomes of thrombocytopenia after HSCT. Previous studies have demonstrated that decitabine, a hypomethylating agent, may reduce platelet transfusions in myelodysplastic syndrome (MDS) patients. The investigators conducted an prospective clinical trial to evaluate the safety and efficiency of rhTPO and decitabine in the treatment of thrombocytopenia following HSCT.
