Summary

Bone marrow failure disease(BMFD) is a kind of bone marrow due to congenital or acquired hematopoietic stem cells (hemopoietic stem cell, HSC) function damage. Allogenic hemopoietic stem cell transplantation (Allo-HSCT) might be the most possible treatment to cure the disease.However, 5-26% of patients have been reported to have delayed platelet engraftment (DPE), which is defined as persistent severe thrombocytopenia (<20 × 109/L) for >35 days after transplantation . To date, no standard treatment and prevention has been recommended for DPE. In patients with DPE, the amount of transfusion, the increased risk of infection, and the prolonged average hospital stay were independent risk factors affecting the prognosis of allo-HSCT patients. Due to continuous and progressive failure in the bone marrow hematopoiesis, thrombocytopenia post HSCT is more common in BMFD patients and often achieves low response to conventional therapy, such as platelet transfusion. Therefore, it is of great significance to effectively promote hematopoietic reconstruction to improve the prognosis of transplant patients.
