AbstractWe performed a prospective study in 17 consecutive patients following Autologous bone marrow (BM) or rhG-CSF primed peripheral blood item cell (PBSC) transplantation, with the objective of comparing immune recovery between both procedures and to evaluate results in rhG-CSF mobilized peripheral blood stem cell transplantation (PBSCT). Kinetics of immune reconstitution showed differences, with a faster recovery of CD3+ and CD8+ T cells, and a more rapid and sustained recovery of CD8+/-/CD56+ natural killer (NK) cells in the PBCSCT group. Autologous bone marrow transplantation (ABMT) was associated with a improved reconstitution of the CD19+/CD5+/-subpopulation. Moreover, rhG-CSF mobilized PBSCT generated a greater recovery of CD8+/-/CD56+ cells than previous data concerning transplantation with peripheral blood (PB) progenitors collected after myelosuppressive chemotherapy or myelosuppressive therapy plus rhG-CSF. Our results show differences in the rate and pattern of B and T lymphocytes reconstitution after ABMT and PBSCT. Additionally, we state an enhancement of CD56+ cells in patients undergoing PBSCT mobilized solely using rhG-CSF.
