Mafosfamide, a cyclophosphamide analog, causes a proinflammatory response and increased permeability on endothelial cells in vitro. Bone Marrow Transplant 2023; 58:407-413. [PMID: 36639572 DOI: 10.1038/s41409-023-01912-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Revised: 12/21/2022] [Accepted: 01/05/2023] [Indexed: 01/15/2023]
Abstract
Post-transplantation cyclophosphamide (PTCy) has decreased GVHD incidence. Endothelial damage in allo-HCT is caused by multiple factors, including conditioning treatments and some immunosupressants, and underlies HCT-complications as GVHD. Nevertheless, the specific impact of PTCy on the endothelium remains unclear. We evaluated the effect of mafosfamide (MAF), an active Cy analog, on endothelial cells (ECs) vs. cyclosporine A (CSA), with known damaging endothelial effect. ECs were exposed to MAF and CSA to explore changes in endothelial damage markers: (i) surface VCAM-1, (ii) leukocyte adhesion on ECs, (iii) VE-cadherin expression, (iv) production of VWF, and (v) activation of intracellular signaling proteins (p38MAPK, Akt). Results obtained (expressed in folds vs. controls) indicate that both compounds increased VCAM-1 expression (3.1 ± 0.3 and 2.8 ± 0.6, respectively, p < 0.01), with higher leukocyte adhesion (5.5 ± 0.6, p < 0.05, and 2.8 ± 0.4, respectively). VE-cadherin decreased with MAF (0.8 ± 0.1, p < 0.01), whereas no effect was observed with CSA. Production of VWF augmented with CSA (1.4 ± 0.1, p < 0.01), but diminished with MAF (0.9 ± 0.1, p < 0.05). p38MAPK activation occurred with both compounds, being more intense and faster with CSA. Both drugs activated Akt, with superior MAF effect at longer exposure. Therefore, the cyclophosphamide analog MAF is not exempt from a proinflammatory effect on the endothelium, though without modifying the subendothelial characteristics.

Abstract
Differentiation of pluripotent stem cells (PSCs) to neural lineages has gathered huge attention in both basic research and regenerative medicine. The major hurdle lies in the efficiency of differentiation and identification of small molecules that facilitate neurogenesis would partly circumvent this limitation. The small molecule Cyclosporine A (CsA), a commonly used immunosuppressive drug, has been shown to enhance in vivo neurogenesis. To extend the information to in vitro neurogenesis, we examined the effect of CsA on neural differentiation of PSCs. We found CsA to increase the expression of neural progenitor genes during early neural differentiation. Gene silencing approach revealed CsA-mediated neural induction to be dependent on blocking the Ca2+-activated phosphatase calcineurin (Cn) signaling. Similar observation with FK506, an independent inhibitor of Cn, further strengthened the necessity of blocking Cn for enhanced neurogenesis. Surprisingly, mechanistic insight revealed Cn-inhibition dependent upregulation of IL-6 protein to be necessary for CsA-mediated neurogenesis. Together, these findings provide a comprehensive understanding of the role of CsA in neurogenesis, thus suggesting a method for obtaining large numbers of neural progenitors from PSCs for possible transplantation.

Abstract
OBJECTIVE Voriconazole as a triazole antifungal agent is widely used for prophylaxis or treatment of fungal infections in allogeneic hematopoietic stem cell transplantation (HSCT). It can increase blood concentrations of other medications including cyclosporine A (CsA) which are substrates for cytochrome P450 3A4. The aim of this study was to evaluate comparatively the interaction between oral/intravenous (IV) voriconazole and oral CsA. METHODS Twenty-nine recipients of allogeneic HSCT who had been already on a steady dose of CsA and were started on oral or IV voriconazole were evaluated in a prospective cohort study. Blood concentration of CsA was determined before and 5-8 days after voriconazole initiation. Plasma concentration of voriconazole was measured in steady state. The changes in blood concentration of CsA after administration of voriconazole were evaluated. FINDINGS The concentration/dose (C/D) ratio of CsA increased significantly (P < 0.001) after voriconazole initiation in both routes of administration (8.40%-174.10% increase in C/D ratio). The C/D ratio alteration of CsA did not differ significantly between oral and IV voriconazole group (P = 0.405). There was a significant correlation in all patients between plasma concentration of voriconazole and percentage of CsA C/D ratio increment (P = 0.046). CONCLUSION There was a significant intrapatient variability in the magnitude of CsA blood concentration increment after voriconazole initiation. We also demonstrated that magnitude of drug interaction did not differ in IV and oral voriconazole administration. Furthermore, we found that the magnitude of drug interaction was correlated with plasma concentration of voriconazole.

Abstract
Haploidentical stem cell transplantation (SCT) offers a transplantation option to patients who lack an HLA-matched donor. We developed a 2-step approach to myeloablative allogeneic hematopoietic stem cell transplantation for patients with haploidentical or matched related (MR) donors. In this approach, the lymphoid and myeloid portions of the graft are administered in 2 separate steps to allow fixed T cell dosing. Cyclophosphamide is used for T cell tolerization. Given a uniform conditioning regimen, graft T cell dose, and graft-versus-host disease (GVHD) prophylaxis strategy, we compared immune reconstitution and clinical outcomes in patients undergoing 2-step haploidentical versus 2-step MR SCT. We retrospectively compared data on patients undergoing a 2-step haploidentical (n = 50) or MR (n = 27) peripheral blood SCT for high-risk hematological malignancies and aplastic anemia. Both groups received myeloablative total body irradiation conditioning. Immune reconstitution data included flow cytometric assessment of T cell subsets at day 28 and 90 after SCT. Both groups showed comparable early immune recovery in all assessed T cell subsets except for the median CD3/CD8 cell count, which was higher in the MR group at day 28 compared with that in the haploidentical group. The 3-year probability of overall survival was 70% in the haploidentical group and 71% in the MR group (P = .81), while the 3-year progression-free survival was 68% in the haploidentical group and 70% in the MR group (P = .97). The 3-year cumulative incidence of nonrelapse mortality was 10% in the haploidentical group and 4% in the MR group (P = .34). The 3-year cumulative incidence of relapse was 21% in the haploidentical group and 27% in the MR group (P = .93). The 100-day cumulative incidence of overall grades II to IV acute GVHD was higher in the haploidentical group compared with that in the MR group (40% versus 8%, P < .001), whereas the grades III and IV acute GVHD was not statistically different between both groups (haploidentical, 6%; MR, 4%; P = .49). The cumulative incidence of cytomegalovirus reactivation was also higher in the haploidentical group compared to the MR group (haploidentical, 68%; MR, 19%; P < .001). There were no deaths from GVHD in either group. Using an identical conditioning regimen, graft T cell dose, and GVHD prophylaxis strategy, comparable early immune recovery and clinical outcomes were observed in the 2-step haploidentical and MR SCT recipients.

Clinical and biological predictors of outcome following relapse of CML post-allo-SCT. Bone Marrow Transplant 2014; 50:189-196.

Abstract
While there are now fewer allogeneic stem cell transplants (allo-SCT) performed for chronic myeloid leukemia (CML), leukemic relapse post-transplant remains a persistent problem. To better define clinical and biological parameters determining post-relapse outcome, we studied 59 patients with CML relapsing after HLA-identical sibling allo-SCT between 1993 and 2008. Eighteen (30.5%) were transplanted in advanced phase and 41(69.5%) in chronic phase. With a median follow up from relapse of 7.9 years, 5-year post-relapse survival (PRS) was 62%. Multivariate analysis found disease status at transplant, time to diagnosis of relapse from transplant, and pre- transplant TKI use as significant factors associated with PRS. Analysis of BCR-ABL transcript expression in the hematopoietic progenitor compartment was performed in 36 patients (22 relapsed, 8 non-relapsed, and 6 TKI alone controls). Patients with BCR-ABL expression in their early hematopoietic stem cell compartment (HSC: Lineage−CD34+CD38-CD90+) had worse survival irrespective of the disease status. We conclude disease status remains the strongest clinical prognostic factor for PRS in CML following allo-SCT. The persistence of BCR-ABL expression in the progenitor cell compartment in some patients after SCT emphasizes the need to target CML-leukemia stem cells.

Abstract
Preemptive therapy at CMV reactivation has diminished post-transplant CMV mortality. Furthermore, recent studies suggest a favorable 'virus-versus-leukemia' effect from reactivating CMV, reducing relapse of AML after SCT. We studied the relationship of CMV reactivation with leukemic relapse in 110 patients with CML receiving HLA-identical sibling SCT between 1993 and 2008. Of these, 79 (72%) were in chronic phase, 5 in second chronic phase, 17 in accelerated phase and 9 in blast phase. A total of 97 patients (88%) received a myeloablative conditioning regimen, 97 received 4-log ex vivo T cell-depleted grafts and 13 received T-replete grafts. CMV reactivation before day 100 was observed in 72 patients (65.5%). At a median follow-up of 6.2 years, CMV reactivation < day 100 as a time-dependent covariate was an independent factor associated with decreased relapse. We conclude that CMV reactivation may contribute to a beneficial GVL effect in CML transplant recipients.

Abstract
Patients with leukemia relapsing after allogeneic hematopoietic stem cell transplantation (SCT) have a dismal prognosis. A second SCT offers a further opportunity for cure, but has a high rate of treatment failure. To determine the utility of this option, we analyzed 59 consecutive patients relapsing after a myeloablative HLA-matched sibling T cell depleted SCT. Twenty five patients (13 relapsing within 6 months and 12 relapsing between 6 – 170 months after the first SCT) received a T-replete second SCT. Thirty-eight patients relapsing early had a shorter survival than the 21 patients relapsing later (median 96 vs 298 days, p = 0.0002). In patients relapsing early, the second SCT did not improve overall survival compared to patients receiving non-SCT treatments (median survival 109 vs 80 days, p = 0.41). In patients relapsing late, despite an early trend in favor of second SCT, overall survival was comparable for patients receiving a second SCT compared with patients not retransplanted (median survival 363.5 vs 162 days, p = 0.49). Disappointingly our results do not demonstrate an important survival benefit for a second T-replete allogeneic SCT to treat relapse following a T cell depleted SCT.

Abstract
Delayed immune recovery is a characteristic feature of allogeneic hematopoietic stem cell transplantation in adult recipients. Although recipient thymic T-cell neogenesis contributes to T-cell regeneration after transplantation, thymic recovery in the transplant recipient decreases with increasing age, and is diminished by intensive preconditioning regimens and graft-versus-host disease. In adult recipients, most events that determine transplant success or failure occur during the period when the majority of circulating T cells is derived from the donor's post thymic T-cell repertoire. As a result, the make-up of the donor lymphocyte compartment may strongly influence immune recovery and transplant outcomes. The aim of this study was to examine donor lymphocyte counts in a series of patients undergoing an allogeneic hematopoietic stem cell transplant to identify the potential contribution of donor regulatory and conventional T lymphocyte populations to immune recovery and transplant outcomes. We examined donor lymphocyte subset counts in relation to post-transplant lymphocyte recovery and transplant events in 220 consecutive myeloablative, T-cell-depleted, HLA-identical sibling hematopoietic stem cell transplant recipients with hematologic malignancies. In a multivariate analysis, absolute numbers of donor CD4(+) recent thymic emigrants were associated with overall survival (P=0.032). The donors' absolute lymphocyte count and thymic production of regulatory T cells were both associated with extensive chronic graft-versus-host disease (P=0.002 and P=0.022, respectively). In conclusion, these results identify donor immune characteristics that are associated with lymphocyte recovery, extensive chronic graft-versus-host disease, and survival in the recipient following allogeneic hematopoietic stem cell transplantation. The study reported here was performed using peripheral blood samples drawn from donors and patients enrolled in the ClinicalTrials.gov-registered trials NCT00001623, NCT00001873, NCT00353860, NCT00066300, NCT00079391, and NCT00398346.

Abstract
After allogeneic stem cell transplantation (SCT), T lymphocyte function is reestablished from the donor's postthymic T cells and through thymic T-cell neogenesis. The immune repertoire and its relation to that of the donor have not been characterized in detail in long-term adult SCT survivors. We studied 21 healthy patients in their second decade after a myeloablative SCT for hematologic malignancy (median follow-up, 12 years). Immune profiles were compared with donor samples cryopreserved at transplant and beyond 10 years from SCT. Only one recipient was on continuing immunosuppression. Compared with the donor at transplant, there was no significant difference in CD4, CD8, natural killer, and B-cell blood counts. However, compared with donors, recipients had significantly fewer naive T cells, lower T-cell receptor excision circle levels, fewer CD4 central memory cells, more effector CD8(+) cells, and more regulatory T cells. TCR repertoire analysis showed no significant difference in complexity of TCRVβ spectratype between recipients and donors, although spectratype profiles had diverged with both gain and loss of donor repertoire peaks in the recipient. In conclusion, long-term allogeneic SCT survivors have subtle defects in their immune profile consistent with defective thymic function but compatible with normal health. This study is registered at http://www.clinicaltrials.gov as NCT00106925.

Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) is a curative treatment for some hematologic malignancies. As the overall number of survivors continues to increase, studies systematically examining outcomes in long-term survivors are needed. We studied the clinical and quality-of-life outcomes in HSCT recipients surviving 5 or more years from HSCT. Since 1993, 262 patients with hematologic malignancies received a T cell-depleted myeloablative HSCT from an HLA-identical sibling at a single center. Ninety-two survived beyond 5 years from HSCT (median follow-up 9.4 years, range: 5.1-15.3). Median age at transplantation was 35 years (range: 10-56). Twenty-two (24%) received a bone marrow transplant, and 70 (76%) received a peripheral blood HSCT. Of the 92 survivors, 60 completed quality-of-life measures. The main outcomes examined were chronic graft-versus-host-disease, disease relapse, survival, health-related quality-of-life (HRQL) (Functional Assessment of Cancer Therapy-General), physical and mental health (SF-36), and symptom experience (Rotterdam Symptom Checklist). Seventy-five (82%) of 92 survivors no longer required systemic immunosuppressive treatment. Four (4.3%) relapsed with leukemia at a median of 8.5 years (range: 6.2-14.0) after HSCT. Four (4.3%) died between 7.4 and 13.4 years post-HSCT (1 relapse, 1 lung cancer, 1 pneumonia, 1 brain hemorrhage). Most survivors beyond 5 years had an excellent performance status with no difference in physical and mental health and higher HRQL scores (P = .02) compared with population norms. Although physical and psychologic symptom distress was low, those with higher symptom distress experienced inferior HRQL. These results show that 5 or more years after T cell-depleted HSCT for hematologic malignancy most individuals survive disease free with an excellent performance status, preserved physical and psychological health, and excellent HRQL.

Abstract
To determine whether the leukemia-associated Wilms tumor antigen (WT1) contributes to a graft-versus-leukemia (GVL) effect after allogeneic stem-cell transplantation (SCT) for acute lymphoblastic leukemia (ALL), we studied CD8(+) T-cell responses to WT1 in 10 human lymphocyte antigen (HLA)-A*0201-positive ALL patients during the early phase of immune recovery after SCT (days 30-120). Seven of 10 patients had detectable WT1 expression in their peripheral blood (PB) before SCT by quantitative reverse-transcription polymerase chain reaction. Using WT1/HLA-A*0201 tetramers and intracellular interferon-gamma (IFN-gamma) staining, WT1(+) CD8(+) T-cell responses after SCT were found only in patients with detectable WT1 expression before SCT (5 of 7 vs. 0 of 3; P < .05). To monitor the kinetics of WT1(+) CD8(+) T-cell responses and disease regression after SCT, absolute WT1(+) CD8(+) T-cell numbers and WT1 expression were studied for each time point. The emergence of WT1(+) CD8(+) T cells was associated with a decrease in WT1 expression, suggesting a WT1-driven GVL effect. Loss of WT1(+) CD8(+) T-cell responses was associated with reappearance of WT1 transcripts, consistent with a molecular relapse (P < .001). WT1(+) CD8(+) T cells had a predominantly effector-memory phenotype (CD45RO(+) CD27(-)CD57(+)) and produced IFN-gamma. Our results support the immunogenicity of WT1 after SCT for ALL and highlight the potential for WT1 vaccines to boost GVL after SCT for ALL.

Abstract
Our purpose was to determine if total body irradiation (TBI) with lung dose reduction protects against subsequent radiation-induced deterioration in pulmonary function. Between July 1997 and August 2004, 181 consecutive patients with hematologic malignancies received fractionated TBI before allogeneic peripheral blood stem cell transplant. The first 89 patients were treated to a total dose of 13.6 Gy. Thereafter, total body dose was decreased to 12 Gy with lung dose reduction to 9 or 6 Gy. All patients underwent pulmonary function test evaluation before treatment, 90 days post-treatment, then annually. Median follow-up was 24.0 months. Eighty-nine patients were treated with lung shielding, and 92 without. At 1-year post transplant, there was a small but significant difference in lung volume measurements between patients with lung shielding and those without. This was not observed at the 2-year time point. When stratified by good (>100% predicted) or poor (</=100% predicted) baseline lung function, patients with poor function demonstrated protection at 1 year with lung shielding, while those with good initial lung function did not. TBI with or without lung dose reduction has a small but statistically significant effect on pulmonary function measured at 1 year but not 2 years post irradiation.

Abstract
We estimated the effect of CD34(+) stem cell dose during peripheral blood stem cell transplantation (PBSCT) in predicting mortality after total body irradiation (TBI). Between 1997 and 2004, 146 consecutive patients with hematologic malignancies received fractionated TBI (12-13.6 Gy) in 8 fractions over 4 days before undergoing PBSCT; 61 patients received TBI with reduced radiation dose to the lung (6-9 Gy). The number of CD34(+) cells transplanted was recorded for all patients. A cubic spline representation for CD34(+) dose within a Cox proportional hazards model was used to model the relationship between the CD34(+) dose and mortality. Median follow-up was 44 months (range, 12-90 months). The CD34(+) cell dose ranged from 2.45 to 15.90 x 10(6) cells/kg (median, 5.15 x 10(6) cells/kg). Risk of mortality decreased with CD34(+) doses between 4-8 x 10(6) cells/kg and then began to increase. For all patients, CD34(+) doses of 5.1-12.9 x 10(6)/kg resulted in at least a doubling of median survival associated with the lowest CD34(+) value. In patients treated with lung dose reduction, a similar range of CD34(+) dose (4.3-10.2 x 10(6) cells/kg) produced at least a 5-fold improvement from the survival associated with the lowest CD34(+) dose; however, the relationship between CD34(+) dose and mortality was not statistically different when analyzed by lung dose reduction. A method for assessing risk of mortality by CD34(+) dose as a continuous variable is presented. Risk of mortality decreased with CD34(+) doses between 4-8 x 10(6) cells/kg and then began to increase.

Abstract
The primary granule proteins elastase (ELA2) and proteinase 3 (PR3) both contain the nonapeptide PR1, which can induce cytotoxic T lymphocyte (CTL) responses against chronic myeloid leukemia (CML) cells. To investigate whether eradication of CML after allogeneic stem cell transplantation (SCT) was influenced by PR3 and ELA2 gene expression or PR1-specific CTL responses, we studied cells from 87 CML patients and 27 HLA-A*0201(+) donors collected prior to T-cell-depleted HLA-identical sibling SCT. For patients in advanced phase (AdP), a higher expression of both PR3 and ELA2 in CD34(+) progenitors before SCT was associated with a lower incidence of relapse-related death, improved leukemia-free survival (LFS), and overall survival (OS); in chronic phase patients, no differences were observed. PR1-CTL responses were detected in 7 of 27 HLA-identical sibling donors, and associated with improved LFS and OS after SCT on follow-up. PR1-CTL responses detected in 7 of 28 CML patients before transplantation were not predictive of outcome and correlated inversely with PR3 and ELA2 expression. These findings suggest that assessment of PR3 and ELA2 expression in leukemic progenitors is useful for predicting posttransplantation outcome in AdP patients undergoing SCT. The presence of a donor immune response against PR1 may be advantageous and could be exploited therapeutically.

Abstract
Pulmonary function (PF) was studied in 69 consecutive patients with hematologic diseases, with a minimum 5-year (range, 5-13 years) follow-up after allogeneic stem cell transplantation from an HLA-matched sibling. Fifty-six patients (81%) received total body irradiation based myeloablative stem cell transplantation (MT) and 13 (19%) underwent nonmyeloablative stem cell transplantation (NST). Thirty-one patients (45%) developed a late decrease in PF from baseline, 25 with a restrictive and 6 with an obstructive pattern PF abnormality. Twelve patients (17%) were symptomatic, 8 with a severe restrictive PF defect, but none required supplemental oxygen. The incidence of developing a late PF abnormality was comparable in MT (24 of 56) and NST (5 of 13; P = .51). In multivariate analysis, chronic graft-versus-host disease (relative risk, 16) and pretransplantation diffusion capacity for carbon monoxide or forced expiratory volume in the first second <80% predicted were independently associated with a late decrease in PF from baseline (relative risk, 7). Our results indicate that late PF abnormality is common after MT and NST. Patients with a low pretransplantation diffusion capacity for carbon monoxide of or forced expiratory volume in the first second who developed chronic graft-versus-host disease were most severely affected. Longer follow-up is needed to determine whether PF will continue to decrease or reach a plateau and whether more patients with PF abnormality will eventually become symptomatic.

Abstract
One hundred thirty-eight patients with hematologic malignancies received myeloablative T cell-depleted peripheral blood stem cell transplant (PBSCT) from an HLA-identical sibling donor. The T cell dose was adjusted to 0.2-1 x 10(5) CD3(+) cells/kg. The CD34 dose was 2.7-16 x 10(6)/kg. Patients with acute graft-versus-host disease (GVHD) grade <2 received 1 or 2 donor lymphocyte infusions of 10(7) CD3(+) cells/kg between days 45 and 100. Patients were designated according to relapse probability as standard or high relapse risk (77 and 61, respectively). Overall survival (OS), relapse-free survival, relapse, and transplant-related mortality (TRM) were 58%, 46%, 40%, and 20%, respectively, after a median follow-up of 4 years. Fifty-three (39%) and 21 (15%) patients developed grade 2-4 and 3-4 acute GVHD. Forty-two (36%) had limited and 29 (25%) had extensive chronic GVHD. In multivariate analysis, disease risk was an independent factor for OS and relapse, day-30 lymphocyte count for OS and TRM, and chronic GVHD for OS and relapse. PBSCT with early T cell add back leads to comparable rates of chronic GVHD compared with T cell-replete PBSCT. However, this chronic GVHD after T cell add back is associated with less mortality and retains a protective effect in terms of relapse, at least in the standard-risk patients.

Abstract
PURPOSE To determine the value of pulmonary function tests (PFTs) done before peripheral blood stem cell transplant (PBSCT) in predicting mortality after total body irradiation (TBI) performed with or without dose reduction to the lung. METHODS AND MATERIALS From 1997 to 2004, 146 consecutive patients with hematologic malignancies received fractionated TBI before PBSCT. With regimen A (n=85), patients were treated without lung dose reduction to 13.6 gray (Gy). In regimen B (n=35), total body dose was decreased to 12 Gy (1.5 Gy twice per day for 4 days) and lung dose was limited to 9 Gy by use of lung shielding. In regimen C (n=26), lung dose was reduced to 6 Gy. All patients received PFTs before treatment, 90 days after treatment, and annually. RESULTS Median follow-up was 44 months (range, 12-90 months). Sixty-one patients had combined ventilation/diffusion capacity deficits defined as both a forced expiratory volume in the first second (FEV1) and a diffusion capacity of carbon dioxide (DLCO)<100% predicted. In this group, there was a 20% improvement in one-year overall survival with lung dose reduction (70 vs. 50%, log-rank test p=0.042). CONCLUSION Among those with combined ventilation/diffusion capacity deficits, lung dose reduction during TBI significantly improved survival.

Abstract
Regulatory T cells (T(reg)s) that constitutively express FOXP3 are instrumental to the maintenance of tolerance and may suppress graft-versus-host disease (GVHD) in humans. To determine whether regulatory T cells in allogeneic stem cell transplants (SCTs) ameliorate GVHD after transplantation, we quantitated the coexpression of FOXP3 on CD4(+) T cells in 32 donor SCTs infused into HLA-matched siblings and examined GVHD incidence in respective recipients. High CD4(+)FOXP3(+) T-cell count in the donor was associated with a reduced risk of GVHD. We monitored T(reg)s during immune reconstitution in 21 patients with leukemia undergoing a T-cell-depleted allogeneic SCT. Early after SCT, there was a significant expansion in the CD4(+)FOXP3(+) T-cell compartment. A low CD4(+)FOXP3(+) T-cell count early after SCT (day 30) was associated with an increased risk of GVHD, and the ratio of CD4(+)FOXP3(+) T cells to CD4(+)CD25(+)FOXP3(-) T cells was significantly reduced in patients with GVHD, suggesting diminished control of effector T cells. Our findings suggest that graft T(reg) content may predict for risk of GVHD after SCT. Determining the T(reg) levels in the donor and manipulating T(reg)s early after transplantation may provide a new approach to controlling GVHD.

Abstract
Green fluorescent proteins (GFPs) have been widely used to monitor gene transfer and expression after lentiviral and oncoretroviral transduction of hematopoietic cells. Studies have shown a complete disappearance of GFP-containing cells after transplantation of GFP-transduced repopulating cells in nonhuman primates that was further shown to be mediated by transgene-specific immune responses. We wished to evaluate whether cyclosporine could prevent immune responses to GFP. We first determined whether an immune response to GFP was responsible for the disappearance of gene-modified cells in dogs. We performed immune assays in two dogs transplanted with lentivirally transduced CD34+ cells. Blood samples were obtained twice per week for up to 800 days and the GFP transgene product was measured by flow cytometry in blood leukocytes. Peripheral blood leukocytes were stimulated in vitro for 5 days, using a panel of GFP peptides. Intracellular levels of tumor necrosis factor alpha (TNF-alpha), measured by flow cytometry, and T cell proliferation after GFP peptide stimulation were measured. Dogs that exhibited a decrease in GFP marking developed potent immune responses in vitro to the transgene product GFP as shown by an increase in GFP-specific TNF-alpha production (p < 0.05) when compared with nontransplanted controls. T cells from dogs with low GFP marking exhibited a significant increase in proliferation in response to GFP peptide stimulation in vitro (p < 0.05). To study whether cyclosporine could inhibit the development of GFP-specific immune responses, we treated five dogs with cyclosporine after transplantation of GFP-transduced hematopoietic cells. Dogs treated with cyclosporine after hematopoietic stem cell transplantation showed stable GFP marking in blood leukocytes over 800 days. Our data suggest that cyclosporine prevents immunoactivation against transgene products after transplantation of GFP-transduced hematopoietic stem cells as indicated by stable GFP marking.

Abstract
Between July 1997 and August 2004, 146 consecutive patients with hematologic malignancies received a T cell-depleted peripheral blood stem cell transplant from an HLA-identical sibling by using total body irradiation (TBI) and cyclophosphamide conditioning regimens. Eighty-five patients received 13.6 Gy of TBI with no lung shielding, and 61 received lung shielding (total lung dose, 6-12 Gy). Ninety-four patients (65.5%) had standard-risk disease; the remainder had more advanced disease or unfavorable diagnoses. Of the 21 transplant-related deaths, 14 were from pulmonary causes (10 idiopathic pulmonary syndromes and 4 from infection) that occurred at a median of 90 days (range, 23-238 days) after transplantation. Independent risk factors for pulmonary transplant-related mortality (PTRM) were pretransplantation diffusion capacity for carbon monoxide (relative risk, 5.7 for diffusion capacity for carbon monoxide <85%), smoking (relative risk, 5.0), and CD34 cell dose (relative risk, 9.4 for a CD34 dose of <5 x 10(6) cells per kilogram). Patients receiving lung shielding had significantly lower PTRM (3.3% versus 14.1%; P = .02) and better overall survival (70% +/- 6% versus 52% +/- 5%; P = .04), but lung shielding was not a significant independent factor for determining PTRM. These results suggest that pulmonary mortality after TBI-based preparative regimens is predictable and that higher CD34 cell doses can reduce the risk.

Abstract
Sixty patients with haematological malignancies received a myeloablative regimen of total body irradiation, cyclophosphamide and fludarabine followed by a T-cell-depleted peripheral blood stem cell transplant from a human leucocyte antigen identical sibling. To improve donor immune function, 1 x 10(7) CD3+ cells/kg were added-back between d 45 and 100. T-cell and myeloid chimaerism were monitored regularly to evaluate the effect of T-cell chimaerism on outcome. The major factor affecting outcome was disease risk, with significantly lower relapse and higher survival in 29 standard risk (SR) patients compared with 31 patients at high risk (HR) for treatment failure (relapse 4.8 +/- 5% vs. 59 +/- 11%, P < 0.0001, and overall survival 93 +/- 5% vs. 39 +/- 10%, P < 0.0001, respectively). Donor myeloid chimaerism reached > or = 95% within 14 d of transplant, but in the first several months, donor T-cell chimaerism was frequently mixed. Full T-cell chimaerism was significantly more frequent in HR vs. SR patients. Landmark analysis at days 30 and 90 in HR patients with mixed versus full T-cell chimaerism, showed relapse probabilities of 50.5 +/- 14% vs. 70 +/- 16% (P = 0.62) and 34.4 +/- 20% vs. 58.8 +/- 15% (P = 0.32) respectively. Early full T-cell engraftment correlated with development of severe acute graft-versus-host disease (GVHD). However, mixed T-cell chimaerism was favourable for reducing GVHD, and did not affect relapse in this small series.

Abstract
Eighty patients with chronic myeloid leukemia (CML) underwent T cell-depleted stem cell transplantation from an HLA-identical sibling, with add-back of donor T cells on days 30 to 45 and days 60 to 100 in patients in whom grade 2 or greater acute graft-versus-host disease (GVHD) developed. The outcomes for 54 patients with chronic-phase (CP) and 26 with advanced-phase (AP) disease were as follows: overall survival, 85% +/- 5% versus 36% +/- 10%; transplantation-related mortality (TRM), 13% +/- 5% versus 43% +/- 11%; and current leukemia-free survival, 76% +/- 6% versus 34% +/- 9%. The day-30 lymphocyte count (LC30) was strongly associated with outcome. For patients in CP with counts greater than the median of 0.30 x 10(9)/L, survival was 100% versus 70% +/- 9% (P = .003); current LFS 100% versus 56% +/- 9% (P = .002); and TRM 0% versus 26% +/- 8% (P = .006). Higher-than-median LC30 correlated significantly with molecular remission (MR) at 3, 6, and 12 months and with higher CD34 doses. Lymphocyte subset analysis performed in 20 patients available for phenotyping showed that LC30 was highly correlated with absolute CD56+CD3- natural killer cell numbers (NK30), which also predicted for survival and MR. CD34 cell dose, LC30, and NK30, but not day-30 CD3+ cell count, were highly correlated and were significant predictors of transplantation outcome. These results suggest that transplanted CD34 cell doses greater than 5 x 10(6)/kg may improve outcomes by increasing the early recovery of NK cells.

Abstract
Stem cell transplantation for myelodysplastic syndrome (MDS) is characterized by high transplant-related mortality (TRM), especially in older patients and those with more advanced disease. Outcome after peripheral blood stem cell transplantation (PBSCT) may be superior to earlier results with bone marrow transplantation. Forty-three patients (aged 12-73 years; median, 49 years) received an HLA-identical sibling donor PBSCT. Twenty three patients aged < or =55 years without prohibitive comorbidity received myeloablative total body irradiation-based conditioning, followed by a T cell-depleted PBSCT and delayed add-back of donor lymphocytes. Older patients or those with comorbidities (n = 20) received reduced-intensity conditioning and an unmanipulated PBSCT. Thirty-seven (86%) had advanced disease (refractory anemia with excess blasts [n = 9], refractory anemia with excess blasts in transformation [n = 6], acute myelogenous leukemia [n = 13], or treatment-related MDS [n = 9]); 6 had low-risk MDS (refractory anemia or refractory anemia with ringed sideroblasts). The median follow-up was 18 months (range, 5-89 months). Actuarial probabilities of 3-year overall survival (OS), disease-free survival, relapse, and TRM were 64%, 59%, 26%, and 23%, respectively, for 34 primary MDS patients. The best results were in 19 patients younger than 50 years of age undergoing myeloablative PBSCT (actuarial probabilities of OS, disease-free survival, relapse, and TRM were 81%, 72%, 22%, and 7%, respectively). Although outcomes for all stages of primary MDS were improved, that for therapy-related MDS remained dismal, with 11% OS, because of a high relapse rate (89%).

Abstract
BACKGROUND The aim of this study was to investigate preservation of anti-leukemic activity and protection from opportunistic infections after transplantation of allogeneic + cells in patients with hematologic malignancies and bad prognosis. Methods Thirty-three patients [median age 42 years, range 23-55 years, diagnosis AML/myelodysplastic syndrome (MDS) 14, ALL nine, CML seven and multiple myeloma (MM) three] received myeloablative conditioning followed by infusion of selected CD34+ cells from matched unrelated donors (31) or HLA-identical siblings (two). Early donor lymphocyte infusions (DLI; 0.5 and 1.0 x 10(6) CD3+ cells/kg) were given while patients were on immunosuppressive therapy. RESULTS Ninety-seven per cent of patients engrafted and 24 of 29 patients surviving more than 30 days received at least one pre-emptive DLI. Three patients (10%) developed acute (a)GvHD (two grade I-II, one grade III-IV) spontaneously, and 16 patients (67%) developed aGvHD after DLI (12 grade I-II, four grade III-IV). Eight of 24 evaluable patients developed chronic (c)GvHD (33%, six limited, two extensive). After a median follow-up of 590 days (range 138-1610 days) 18 patients were alive (55%), 16 in complete remission (CR), one in hematologic and one in molecular relapse. Seven patients died after relapse (21%) and eight died from transplantation-related causes (24%). Patients with myeloid malignancies had a significantly better survival than patients with ALL or MM (74%+/-10 vs. 30%+/-13, P<0.05). DISCUSSION Early pre-emptive low-dose DLI following transplantation of selected CD34+ cells from unrelated donors after myeloablative conditioning is feasible and effective without undue toxicity, especially in patients with myeloid malignancies.

Abstract
Numerous clinical studies link cytomegalovirus (CMV) infection with incomplete posttransplantation T-cell recovery. We hypothesized that the inability of transplant recipients to handle CMV reactivation might correlate with a defective graft-versus-leukemia response and increased posttransplantation morbidity. Between May 1995 and August 2001, 82 patients who were CMV seropositive and survived the first 100 days after transplantation were identified for a day 100 landmark analysis of the effect of CMV reactivation patterns on eventual transplantation outcome. All patients underwent a myeloablative HLA-identical sibling donor T cell-depleted stem cell transplantation with scheduled donor T-cell add-back on day 45. Median follow-up was 1032 days. Forty-two patients who had either no reactivation or only 1 positive test with quick clearance were designated as a CMV immune competent group. Forty patients designated as CMV immune deficient (ID) had at least 2 positive tests. Apart from younger age (33 versus 38 years; P =.05) in the ID group, the 2 groups were balanced for clinical characteristics. In multivariate analysis, ID patients had a significantly higher incidence of leukemia relapse (58% versus 21%; P =.03) and worse disease-free survival (31% versus 66%; P =.04). There was no significant difference in week 1 to 14 posttransplantation lymphocyte counts between the 2 groups. In 67 patients tested 3 to 6 months after transplantation, a proliferative response to CMV antigen (stimulation index > or =2) occurred in 27 of 36 immune competent patients compared with 15 of 31 ID patients (P =.006). These results show that recurrent CMV reactivation in the first 100 days after transplantation predicts for reduced disease-free survival and increased leukemic relapse beyond 100 days and correlates with inferior proliferative responses to CMV. The higher relapse rate may reflect poor immune reconstitution in ID patients or an adverse effect of prolonged antiviral treatment.
