Abstract

Apheresis-derived hematopoietic progenitor cells have recently been used for allogeneic transplantation. Forty-one normal donors were studied to assess the effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) (12 micrograms/kg/d) on the peripheralization of hematopoietic progenitor cells and lymphoid subsets. The white blood cell, polymorphonuclear cell (PMNC), and lymphocyte concentrations at the peak of rhG-CSF effect in the donor's peripheral blood (PB) exceeded baseline by 6.4-, 8.0-, and 2.2-fold, respectively. Corresponding concentrations of PB CD34+ cells and primitive subsets such as CD34+ Thy-1dim, and CD34+ Thy-1dim CD38- cells increased by 16.3-fold, 24.2-fold, and 23.2-fold, respectively in eight normal donors. The percentage of CD34+ Thy-1dim and CD34+ Thy-1dim CD38- cells among CD34+ cells increased as well, suggesting an additional peripheralization effect of rhG-CSF on primitive CD34+ subsets. The preapheresis PB CD34+ and CD34+ Thy-1dim cell concentrations were predictive of their corresponding apheresis yield per liter of donor blood processed PB lymphoid subsets were not significantly affected by rhG-CSF treatment. The mean apheresis-derived yield of CD34+, CD34+ Thy-1dim, and CD34+ Thy-1dim CD38- cells per kilogram of recipient body weight and per liter of donor blood processed was 48.9 x 10(4) (n = 41), 27.2 x 10(4) (n = 10), and 1.9 x 10(4) (n = 10), respectively. As compared with 43 single bone marrow (BM) harvest, the CD34+ cell yield of peripheral blood progenitor cell allografts of 41 normal donors exceeded that of BM allografts by 3.7-fold and that of lymphoid subsets by 16.1-fold (CD3+), 13.3-fold (CD4+), 27.4-fold (CD8+), 11.0-fold (CD19+), and 19.4-fold (CD56+CD3-). All PBPC allografts were cryopreserved before transplantation. The mean recovery of CD34+ cells after freezing, thawing, and washing out dimethylsulfoxide was 86.6% (n = 31) and the recovery of lymphoid subsets was 115.5% (CD3+), 121.4% (CD4+), 105.6% (CD8+), 118.1% (CD19+), and 102.4% (CD56+CD3-). All donors were related to patients: 39 sibling-to-sibling, 1 parent-to-child, and 1 child-to-parent transplant. Thirty-eight transplants were HLA fully identical, two transplants differed in one and two antigens. Engraftment occurred in 38 recipients; two patients died too early to be evaluated, and one patient did not engraft. The lowest CD34+ cell dose transplanted and resulting in complete and sustained engraftment was 2.5 x 10(6)/kg of recipient body weight. There was no significant correlation between the total number of CD34+ cells transfused and the time to reach PMNC >0.5 x 10(9)/L or platelets > 50 x 10(9)/L posttransplant, nor was there a correlation found between the total number of CD3+, CD4+, and CD8+ cells transfused and the development of acute graft-versus-host disease (GVHD). The actuarial probability of developing acute GVHD in 38 evaluable patients was 48%. In 13 patients followed longer than 100 days posttransplant, the actuarial probability of developing chronic GVHD was 66% (median follow-up, 264 days).
