Recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) stimulates the growth of myeloid leukemic cells and increases their susceptibility to cell-cycle specific agents. We treated a patient with acute myelogenous leukemia (AML) in a state of second resistant relapse, with high-dose chemoradiotherapy combined with rhGM-CSF (total body irradiation: TBI 3Gy x 4, on days -8 & -7; cytosine arabinoside: Ara-C 3g/m2, iv, q12h, on days -5-2; rhGM-CSF 250 micrograms/m2/day, cont.iv, on days -5-2) followed by autologous peripheral blood stem cell transplantation (PBSCT). In this case, rhGM-CSF enhanced the proliferation of leukemic cells in vitro. The test dose of rhGM-CSF (84 micrograms/m2 over 8 hours) also promoted leukemic cell proliferation in vivo, resulting in an increase in the percentage of leukemic cells in the peripheral blood and reappearance of chromosomal aberrations in the bone marrow. The toxicity of rhGM-CSF-combined conditioning regimen included fever and mild liver damage. The patient achieved a complete remission lasting for 2 months, then relapsed. The rhGM-CSF-combined conditioning regimen was tolerated by this patient, but further studies will be required to confirm not only its safety but also its effectiveness in the treatment of refractory AML.

The objective of this study was to assess the pharmacokinetics of rhG-CSF after a single intraperitoneal injection 2 h post-TBI in B6D2F1 lethally irradiated mice and to analyze the effect of rhG-CSF on the endogenous response of interleukin-3 (IL-3), interleukin-6 (IL-6) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in these animals. For comparison, these cytokine serum levels have also been measured in nonirradiated mice. The serum concentrations of rhG-CSF in irradiated mice were higher than in nonirradiated mice at all time points during the first 60 min after injection. Furthermore, rhG-CSF administration failed to induce detectable endogenous serum levels of IL-3, IL-6 and GM-CSF, at least in the 72-hour period after administration of the rhG-CSF. The radioprotective effect of rhG-CSF in lethally irradiated mice is not mediated by an increase in endogenous serum levels of these three cytokines.

In this prospective study, the effects of granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) on immunological reconstitution after autologous peripheral blood stem cell transplantation (PBSCT) were investigated for 6 months. Thirty-five patients received G-CSF 5 microg/kg per day and 26 patients received GM-CSF SC 5 microg/kg per day from day 1 to leukocyte engraftment (>1000 per mm3). Peripheral blood samples were obtained on 14, 28, 100, and 180 days after transplantation for immunological evaluation. CD3+, CD4+, CD8+, CD19+, and CD56+ cells were analysed by flow cytometry. Immunoglobulin levels (IgG, IgA, and IgM) and complement levels (C3c and C4) were measured by nephelometry. Both G-CSF and GM-CSF groups were comparable with respect to age, sex, the period from diagnosis to transplantation, total nucleated cells infused, the number of CD34+ cells, conditioning regimens (TBI and non-TBI), and post-transplant infection. CD3+ and CD8+ cells on day 14 following autologous PBSCT + G-CSF were significantly higher than following autologous PBSCT + GM-CSF (p = 0.008 and p = 0.021, respectively). The number of CD4 cells and the CD4/CD8 ratio were not different at several time points between the two groups. CD19+, CD56+ cells and immunoglobulin levels showed a faster recovery pattern in the autologous PBSCT + G-CSF group. The effect of G-CSF on immune reconstitution after autologous PBSCT is more prominent than that of GM-CSF. The possible role of haematopoietic growth factor on immune recovery and its clinical importance should be investigated in further studies.
