Abstract

Peripheral blood stem cells (PBSCs) collected following stimulation with cytokines are commonly used for autologous haematopoietic transplants. Currently, PBSCs are being used for syngeneic or allogeneic transplants from matched or haploidentical donors. However, many issues are still unanswered regarding the early or late side-effects cytokines have on recipients and on healthy donors. The aims of this paper were to evaluate the experience acquired worldwide in this field, to define the acceptability of stem cell donation by G-CSF-stimulated apheresis from unrelated donors after the failure of a first donation, and to assess side-effects of G-CSF on unrelated donors. The use of PBSCs has increased tremendously over the last few years and in the near future PBSCs will probably become the most relevant source of stem cells. Studies conducted so far have definitely concluded that G-CSF is safe and well tolerated. Results observed in transplants utilizing marrow stem cells compared with results obtained in transplants utilizing PBSCs have shown that patients undergoing this latter procedure recover earlier, require a lower number of transfusions and spend fewer days in hospital with a consequent decrease in costs. We concluded that a second transplant by G-CSF-stimulated apheresis from an unrelated donor is definitely acceptable and we designed a prospective study to better define all controversial aspects. Donors will be given 10 microg/kg/day of G-CSF subcutaneously for 5 days. One or two PBSC collection procedures will be performed: the first on day 5 and the second, if necessary, on day 6. Donors will be surveyed and blood counts monitored in a standardized manner during the process.
