Abstract:
Objective To evaluate the efficacy and safety of the mobilization and collection of unrelated allogeneic peripheral blood stem cells. Methods The suitable stem cell mobilization plan was made in accordance with the hematopoietic stem cell mobilization plan of China Marrow Donor Program, the ruler of the hospital, and the donor's constitution. The unrelated allogeneic peripheral blood stem cells of 64 healthy donors were collected in the second Hospital of Shanxi Medical University from May 2012 to January 2017. The donor was infected one or several times with the mobilization agent granulocyte colony stimulating factor (G-CSF) by 5-10 μg·kg-1·d-1. After 3-4 days, peripheral blood hematopoietic stem cells were collected using COBE Spectra blood cell separator. Then, the effect and adverse reaction of donors were analyzed from different age and sex. Results It can achieve the acquisition requirements using 3 or 4 days of mobilization programs, mononuclear cells≥5.0×108/kg, CD34+cells≥2.0×106/kg. The single acquisition success rate (the target acquisition of the number of mononuclear cells and CD34+) up to 65 ％, collection efficiency reached 52％, which could reduce the risk of donor and the cost of patients. The quality of donor stem cell of young was better than that of older persons. Sixteen donors (25％) had mild adverse reactions, and no special treatment was required. Conclusions Allogeneic stem cell mobilization is safe. Starting from save medical resources and the interests of the donor the 3 day or 4 days of mobilization scheme could improve the success rate of the single mobilization. During the collection process, the condition of donor hypocalcemia should be observed and health education should be given to relieve the tension of donor.
