A comparison of effect of single versus double daily dose of human granulocyte colony-stimulating factor on mobilization of peripheral hematopoietic stem cells in healthy donors / 解放军医学杂志

ABSTRACT

Objective To compare the results of mobilization of peripheral stem cells of two different G-CSF dosage schedules in 30 healthy donors. Methods In one group 15 healthy subjects received 5?g/kg filgrastim once daily subcutaneously (SC), while in the other group another 15 individuals received 2.5?g/kg of filgrastim twice daily SC. Peripheral blood stem cells were collected after five days of filgrastim administration, and flow cytometric immunophenotyping was performed for the first harvest. Results The MNC count was 2.93?10 8/kg donor body weight in the 5?g/kg Qd group compared with 4.42?10 8/kg in the 2.5?g/kg bid group (P0.05). Conclusion Administration of filgrastim twice a day at 2.5?g/kg instead of once a day at 5?g/kg is more efficient in mobilizing stem cells without obvious side effect.
