ABSTRACT
This study was aimed to investigate the effects of different mobilization methods on mobilization and collection of peripheral blood stem cells in healthy donors and the adverse effect of collection, as well as hematopoietic construction in recipients. A total of 43 donors between January 2008 and May 2013 were divided into the simple mobilization group and the combined mobilization group. The simple group was subcutaneously injected with 5.0-10.0 µg/(kg·d) recombinant human granulocyte colony-stimulating factor (rhG-CSF), and the combined mobilization group was treated with rhG-CSF and intravenously dripped with 10 mg dexamethasone for 2-4 hours before collection. The acquisition and count of MNC and CD34(+) cells in different groups, the relationship between the stem cells and MNC count in blood before collection, and the adverse reactions were analyzed; the hematopoietic reconstruction of recipients was investigated. The results showed that the hematopoietic stem cell number of the two groups meet the demands. The count of MNC and CD34(+) cells in the simple mobilization group was more than that in the combined mobilization group. The MNC count in two groups positively correlated with peripheral blood MNC count before collection. The decline of hemoglobin and platelet levels was more obvious in the simple mobilization group than that in combined mobilization group. The adverse reactions of collection in the simple mobilization group could be well tolerated and reversed. There was no adverse reaction in the combined mobilization group. The differences of conditioning regimens between two groups were not statistically significant and the hematopoietic reconstruction time of combined group was shorter than that in the simple mobilization group.It is concluded that the adverse reactions in process of collection can be reduced, and enough hematopoietic stem cells can be collected by G-CSF plus dexamethasone in mobilization of peripheral blood stem cells. The count of MNC in peripheral blood before collection can be still used as a reference index to evaluate the acquisition of MNC. Especially the combination with dexamethasone for stem cell mobilization can promote the hematopoietic reconstruction of the recipients.
