Peripheral blood stem cells (PBSCs) are widely used in autologous transplantation because of ease of collection and rapid hematopoietic reconstitution. However, PBSCs have rarely been used for allogeneic transplantation because of concerns about donor toxicities from cytokine administration and the theoretical increased risk of graft-versus-host-disease (GVHD) from the large number of T cells infused. Eight patients with advanced malignancies received allogeneic PBSC transplants from genotypically HLA-identical sibling donors. All donors received 5 days of recombinant human granulocyte colony-stimulating factor (rhG-CSF; 16 micrograms/kg/day) subcutaneously and were leukapheresed for 2 days. After treatment of the patient with total body irradiation and cyclophosphamide (n = 7) or etoposide, thiotepa, and cyclophosphamide (n = 1), PBSCs were infused immediately after collection and without modification. All patients received cyclosporine and either methotrexate (n = 6) or prednisone (n = 2) for GVHD prophylaxis, rhG-CSF was well tolerated with mild bone pain requiring acetaminophen occurring in two donors. All patients engrafted and in seven hematopoietic recovery was rapid, with 500 neutrophils/microL achieved by day 18 and 20,000 platelets/microL by day 12. Complete donor engraftment was documented by Y chromosome analysis in all four sex-mismatched donor-recipient pairs tested and by DNA analysis in two sex-matched pairs. One patient died on day 18 of veno-occlusive disease of the liver with engraftment but before chromosome analysis could be performed (results are pending in 1 patient). A second patient died of fungal infection 78 days after transplant. Grade 2 acute GVHD occurred in two patients and grade 3 GVHD occurred in one patient. One patient is 301 days from transplant in remission with chronic GVHD; the remaining five patients are alive and disease free 67 to 112 days after transplantation. Preliminary results indicate that allogeneic PBSCs mobilized by rhG-CSF can provide rapid hematologic recovery without an appreciably greater incidence of acute GVHD than would be expected with marrow. Further follow-up is required to determine the incidence of chronic GVHD and any potential beneficial effects on relapse after transplant.

Most children with acute lymphoblastic leukemia (ALL) are successfully treated by chemotherapy. For those patients, who relapse on therapy, bone marrow transplantation (BMT) is considered most appropriate after a subsequent remission is achieved. Three boys with ALL aged from 9 to 13 years met these criteria and received BMT from their HLA-compatible sisters after marrow ablation with total body irradiation 12 Gy plus high dose cytosine arabinoside 3 gm/m2/12h x 12 doses and graft-versus-host disease (GVHD) prophylaxis with cyclosporine plus short course methotrexate from March 10, 1989 to May 23, 1992. Filgrastim (rhG-CSF) was used to hasten the recovery of granulocyte in one patient. All three patients got full engraftment and two had grade 1 acute GVHD. None of them developed chronic GVHD. Two patients have disease-free survival over 51 and 12 months respectively post BMT without further chemotherapy. One patient died of recurrent refractory leukemia 5 months after BMT. The toxicity of this conditioning regimen included photophobia, conjunctivitis and erythematous skin rashes. One patient who received filgrastim from day 1 to 21 developed severe bone pain. However, this patient had faster recovery of granulocyte count than the other two patients. The preliminary results of this work favors BMT for children with recurrent ALL whose ultimate survival is usually poor when treated with chemotherapy. Further efforts are necessary to investigate new methods for reducing leukemic relapse in ALL patients undergoing BMT.

Recombinant G-CSF has been given to over 150 normal donors for the collection of allogeneic or syngeneic peripheral blood stem cells (PBSCs). G-CSF was found to be well-tolerated with mild-moderate bone pain, edema and mild thrombocytopenia being the observed side effects. To date, approximately 100 unmodified primary PBSC transplants from HLA-identical related donors have been performed with engraftment that is, in general, considerably more rapid than marrow. Acute graft-versus-host-disease (GVHD) grades II-IV occurred in 44% of patients and grades III-IV in 16%. From a small number of evaluable patients surviving for more than 100 days, it appears the incidence of chronic GVHD is approximately 50%. Despite the infusion of one to two logs more T cells, these results are not remarkably different than would be expected with marrow transplantation. Further studies are needed to define the role of allogeneic PBSCs for transplantation, to refine PBSC mobilization and collection techniques, and to evaluate the long-term effects of cytokines in normal donors.

Recombinant G-CSF has been given to over 150 normal donors for the collection of allogeneic or syngeneic peripheral blood stem cells (PBSC). G-CSF was found to be well-tolerated with mild-moderate bone pain, edema and mild thrombocytopenia being the observed side effects. To date, approximately 90 unmodified primary PBSC transplants from HLA-identical related donors have been performed with engraftment that is, in general, considerably more rapid than marrow. Acute graft-versus-host-disease (GVHD), grades II-IV occurred in 47% of patients and grades III-IV in 17%. Despite the infusion of one to two logs more T cells, these results are not remarkably different than would be expected with marrow transplantation. There have also been successful reports of using G-CSF mobilized allogeneic PBSC following second transplants for graft rejection or relapse. Allogeneic PBSC have been infused without reconditioning for correction of graft failure and unmodified or CD34 selected PBSC have also been given with marrow to augment the dose of hematopoietic cells. Further studies are needed to define the role of allogeneic PBSC for transplantation, refine PBSC mobilization and collection techniques and to evaluate the long-term effects of cytokines in normal donors.

Six patients with high-risk leukaemia received a myeloablative regimen followed by allogeneic peripheral blood progenitor cells transplantation (PBPCT) from an HLA-identical sibling donor. Donors received 10-12 mu g/kg/day of G-CSF subcutaneously for 5 days. G-CSF was well tolerated except for moderate bone pain. Peripheral blood leukapheresis product contained 1-4 times more CD34+ cells and approximately a log more of T lymphocytes than marrow grafts from normal donors. In the two first cases the leukapheresis product was partially depleted of T-lymphocytes using counterflow centrifugation. No growth-factors were administered post-transplant. GVHD prophylaxis consisted of cyclosporin A (CyA) in one case, and CyA and methotrexate in five cases. All patients engrafted with a neutrophil count reaching more than 0.5 x 10(9)/L by day 12 to 21 post-transplant and a platelet count above 20 x 10(9)/L by day 6 to 41 post-transplant. Acute GVHD was clinical grade 0 (n = 2), I (n = 1), II (n = I), grade III (n = I) and grade IV (n = 1). One case presents an extensive chronic cutaneous GVHD and is currently being treated with methylprednisolone. In conclusion, allogeneic transplants using PBPC can be performed safely. This may result in a rapid neutrophil and platelet engraftment, without an apparent increased risk of GVHD.

We conducted a comparative study on a daily single versus a divided dose of G-CSF for G-CSF-induced mobilization of peripheral blood stem cells (PBSC) in eleven HLA-identical sibling donors of allogeneic PBSC transplantation (PBSCT). Six donors received double subcutaneous injections of G-CSF at a dose of 5 micrograms/kg x 2/day for 5 days (Group A), while the remaining five received single subcutaneous injection at a dose of 10 micrograms/kg/day for 5 days (Group B). The numbers of circulating CD34+ cells, myeloid progenitors (CFU-GM) and erythroid progenitors (BFU-E) reached peak values at day 5 of G-CSF administration in both groups. The mean number of CD34+ cells harvested per apheresis was 4.4 x 10(6)/kg (cells/body weight of each donor, range: 0.8-7.9 x 10(6)/kg) in Group A and 5.1 x 10(6)/kg (range: 3.0-9.0 x 10(6)/kg) in Group B. There were no significant differences between these two groups in total numbers of CFU-GM, BFU-E, or T-lymphocytes harvested. Adverse effects including mild to moderate bone pain and thrombocytopenia were transient and well tolerated. No difference was observed in the incidence of adverse effects between the two groups. These observations suggest that there is no difference in G-CSF-induced mobilization of PBSC between daily single and divided dose of G-CSF to collect a sufficient number of PBSC for engraftment after allo-PBSCT.

Fifteen patients with hematological malignancies [9 acute nonlymphoblastic leukemia (ANLL), four chronic myelogenous leukemia (CML), two acute lymphoblastic leukemia (ALL)] received allogeneic peripheral blood stem cell transplantation (alloPBSCT) from HLA-identical sibling donors. Donors received 2.5-15 micrograms/kg/day of recombinant human granulocyte colony stimulating factor (rhG-CSF) for 5-10 days. Administration of rhG-CSF was well tolerated except for mild to moderate bone pain occurring in all the donors which was relieved by oral paracetamol. A total of 40 leukaphereses were performed for the 15 donors using the bilateral antecubital veins. None of the donors needed central venous line insertion. The median number of apheresis procedures for each patient was 3 (2-3). A median of 7.7 (4-38.2) x 10(8)/kg mononuclear cells, 35 (2.4-90.0) x 10(6)/kg CD34+ cells, 1.85 (0.45-4.8) x 10(8)/kg CD3 and 0.3 (0.16-1.01) x 10(8)/kg natural killer cells were given without any manipulation. Cyclosporin A (CsA) plus short-course methotrexate (MTX) (12 patients) and CsA alone (3 patients) were used for graft versus host disease (GVHD) prophylaxis. Median granulocyte and platelet engraftments were done on days 11 (10-31) and 16 (11-54) respectively. Grades II-IV GVHD occurred in 62% of the patients and grades III-IV in 15%. Twelve patients are still alive with full engraftment and disease-free. In conclusion, alloPBSCT is an alternative to allogeneic bone marrow transplantation, because of the ease of collection and rapid hematological recovery. However, there is a trend for increased acute GVHD in our leukemia patients compared to allogeneic bone marrow.

Allogeneic peripheral blood stem cell transplantation from an HLA-identical sibling was performed for a 38-year-old male with refractory acute myeloblastic leukemia. The patient was conditioned with total body irradiation (TBI) and high-dose cytosine arabinoside (Ara-C). G-CSF (300 microg/body) was started for priming of residual leukemic cells 24 hr before the beginning of TBI (day -9). However, intolerable generalized bone pain appeared shortly after the start of first dose of G-CSF, and persisted for 3 days in spite of the cessation of G-CSF. Posttransplant hematopoietic engraftment was very rapid. Bone marrow biopsy specimens on day 14 and 30 showed typical bone marrow necrosis histologically. This is the first case of bone marrow necrosis during administration of G-CSF, and our experience suggests that PBSC could repopulate hematopoiesis in spite of severe bone marrow necrosis.

We describe an ALL patient who developed extensive bone marrow necrosis at the time of relapse 2 months after allogeneic bone marrow transplantation from an HLA-identical sibling. The excruciating and diffuse bone pain, fever and precipitous drop in peripheral blood counts were characteristic. This case illustrates the importance of repeat bone marrow biopsies for the diagnosis of disease relapse and the potential application of MR imaging in the assessment of patients with bone marrow necrosis.

Gene therapy is becoming one of the most promising modalities for the treatment of acquired immunodeficiency syndrome. The purpose of this study was to investigate the mobilization and collection of peripheral blood progenitor cells from human immunodeficiency virus (HIV)-infected individuals using granulocyte colony-stimulating factor (G-CSF). A total of 10 patients (9 male, 1 female; median age 36.5 years) with varying circulating CD4+ cell counts (13.9-1467/microL) were administered 10 microg/kg G-CSF daily for 6 days. Peripheral white blood cells (WBCs), CD34+ cell counts, lymphocyte subsets, and plasma viremia were monitored before each G-CSF injection. An average sixfold increase in WBCs was observed, which stabilized on day 4 or thereafter. The level of CD34+ cells was increased by 20-fold, and did not differ between days 5 and 6. Smaller increases in CD4+, CD8+, and CD4+CD8+ cells were observed. HIV viral load, as measured by RNA copy number in plasma, was not significantly altered by G-CSF administration. The leukapheresis product (LP), collected on day 7, contained an average of 6.25+/-4.52 (mean +/- standard deviation) x 10(10) WBCs and 3.08+/-2.98 x 10(6) CD34+ cells/kg. The levels of different CD34+ cell subsets were similar to those in the LPs of G-CSF-mobilized healthy individuals from an earlier study. Primitive hematopoietic cells (CD38- and CD38-HLA-DR+ cells) were detected in LPs (1.19+/-0.46% and 0.87+/-0.23%, respectively, of CD34+ cells). All parameters (WBC counts, lymphocyte populations, CD34+ cells, and HIV-1 RNA copies) measured 3 weeks after leukapheresis returned to baseline values. The administration of G-CSF was well tolerated by the HIV patients; side effects included bone pain, headache, flulike symptoms, and fatigue. There were no correlations between baseline CD4+ cell count and the WBCs, mononuclear cells, or CD34+ cells collected in the LP. Similarly, no correlation existed between baseline CD4+ and CD34+ cells, peak CD34+ cells, or days to achieve peak CD34+ cell counts after G-CSF mobilization. Our results showed that: (1) maximal mobilization can be achieved after 4 days of G-CSF administration; (2) therapeutic quantities of hematopoietic cells can be collected and used for gene therapy; and (3) G-CSF administration is well tolerated and does not cause a clinically significant increase in viremia.
