[Mobilization of peripheral blood cells for auto- and allogenic transplantations of hemopoietic cells].

AIM: To study mobilisation of peripheral blood stem cells (PBSC) via single and split subcutaneous injection of granulocytic colony-stimulating factor (G-CSF) and isolation of PBSC concentrates for their transplantation with leukapheresis (LA) and large volume leukapheresis (LVL) in patients with solid tumors and hematological diseases as well as in the group of relative donors. MATERIAL AND METHODS: LA procedures were made on cell blood fractionator COBE Spectra. In groups 1 and 2 LVL was made with apparatus perfusion of circulating blood of the patient or donor (15-33 l) vs 7-12 l in LA by standard technique in group 3. To reduce the volume of sodium citrate solution used in LVL, to prevent citrate intoxication and hypervolemia, a sharp rise of anticoagulant/blood ration was applied. RESULTS: PBSC-mobilisation with split doses of G-CSF and large volume leukapheresis in 23 patients and 11 relative donors vs mobilisation in 26 patients with single-daily dose of G-CSF and leukapheresis of 3 TBV has revealed that split administration of G-CSF increased the number of leukocytes and CD34+ cells more considerably. CONCLUSION: LVL provides PBSC dose sufficient for transplantation during one procedure in the majority of donors and relative donors. This makes the method more comfortable and cost-effective.
