BACKGROUND: Preliminary evidence indicates that the addition of low dose TBI (2-4 Gy) to reduced intensity conditioning may reduce the rate of relapse in allogeneic stem cell transplants. In very high risk patients receiving combination haploidentical-single unit cord blood transplants, we have added 4 Gy TBI to the widely used fludarabine, melphalan conditioning regimen, in hopes of reducing relapse and decreasing graft rejection. METHODS: We retrospectively reviewed the posttransplant outcomes of patients who underwent haplo-cord SCT between May 2013 and March 2015 and who received fludarabine 30mg/m2 D-7 to -3, melphalan 140mg/m2 D-2, and 2 Gy TBI D-4 and -3...

Umbilical cord blood (UCB) engraftment is in part limited by graft cell dose, generally one log less than that of bone marrow (BM)/peripheral blood (PB) cell grafts. Strategies toward increasing hematopoietic stem/progenitor cell (HSPC) homing to BM have been assessed in order to improve UCB engraftment. Despite recent progress, a complete understanding of how HSPC homing and engraftment are regulated is still elusive. We provide evidence that blocking erythropoietin (EPO)-EPO receptor (R) signaling promotes homing to BM and early engraftment of UCB CD34(+) cells...

The success of stem cell therapy is highly dependent on accurate delivery of stem cells to the target site of interest. Possible ways to track the distribution of MSCs in vivo include the use of reporter genes or nanoparticles. The U.S. Food and Drug Administration (FDA) has approved ferumoxytol (Feraheme® [USA], Rienso® [UK]) as a treatment for iron deficiency anemia. Ferumoxytol is an ultrasmall superparamagnetic iron oxide nanoparticle (USPIO) that has recently been used to track the fate of transplanted cells using magnetic resonance imaging (MRI)...

Pulmonary arterial hypertension (PAH) is a life-threatening disorder with a poor prognosis and causes pulmonary vascular remodeling accompanied with increased pulmonary arterial medial wall thickness and fibrosis, which leads to vascular and right ventricular (RV) dysfunction. Despite treatment with prostacyclin, endothelin antagonist, and phosphodiesterase-5 inhibitors the 1-year mortality rate of PAH still remains high. Recent registries, clinical trials, and basic researches have been increasing the knowledge of PAH and it would contribute to potential therapeutic strategies and better clinical outcome...

The effect of graft-versus-host disease (GVHD) on transplant outcomes after unrelated cord blood transplantation (UCBT) has not been fully elucidated. We analyzed the impact of acute and chronic GVHD on outcomes in adult patients with acute leukemia or myelodysplastic syndrome who underwent their first UCBT (n=2558). The effect of GVHD on outcomes was analyzed after adjusting for other significant variables. The occurrence of GVHD was treated as a time-dependent covariate. The occurrence of grade 1-2 or 3-4 acute GVHD was significantly associated with a lower relapse rate...

PURPOSE: Pediatric inflammatory bowel disease (IBD) is a heterogeneous disorder caused by multiple factors. Although genetic and immunological analyses are required for a definitive diagnosis, no reports of a comprehensive genetic study of a Japanese population are available. METHODS: In total, 35 Japanese patients <16 years of age suffering from IBD, including 27 patients aged <6 years with very early-onset IBD, were enrolled in this multicenter study. Exome and targeted gene panel sequencing was performed for all patients...

BACKGROUND: Since the turn of the last century, the prospect of head transplantation has captured the imagination of scientists and the general public. Recently, head transplant has regained attention in popular media, as neurosurgeons have proposed performing this procedure in 2017. Given the potential impact of such a procedure, we were interested in learning the history of the technical hurdles that need to be overcome, and determine if it is even technically possible to perform such a procedure on humans today...

The development of nephrotic syndrome (NS) after umbilical cord transplantation (UBT) has been reported in only four cases to date. We herein report the case of a 50-year-old woman who developed NS 94 days after UBT. She fell into oliguria and required dialysis. A kidney biopsy revealed focal and segmental glomerulosclerosis. Although glucocorticoid monotherapy did not improve her condition, the addition of low-density lipoprotein (LDL) apheresis resulted in remission of NS, a drastic improvement in her renal function, and withdrawal from dialysis...

Human herpesvirus-6B (HHV-6B) commonly reactivates after umbilical cord blood transplant (UCBT) and is associated with delayed engraftment, fever, rash, and CNS dysfunction. Recently CD134 (OX40) has been implicated as a potential viral entry receptor. We evaluated CD4(+)CD134(+)/(neg-lo) and CD8(+) CD134(+)/(neg-lo) cells at day +28 after UCBT in 20 subjects with previously documented HHV-6 reactivation and persistent viremia. Analysis of CD4(+)CD134(+) cells compared to CD4(+)CD134(neg-lo) cells showed 0...

Successful immune reconstitution (IR) is associated with improved outcomes following pediatric cord blood transplantation (CBT). Usage and timing of anti-thymocyte globulin (ATG), introduced to the conditioning to prevent graft-versus-host-disease and graft failure, negatively influences T-cell IR. We studied the relation between ATG exposure, IR and clinical outcomes. All pediatric patients receiving a first CBT between 2004-2015 at the University Medical Center Utrecht were included. ATG-exposure measures were determined with a validated PK-model...

Unrelated cord blood transplantation has become a reliable alternative therapy for children and adults owing to that one or two antigen/allele mismatches between a patient and the cord blood donor are acceptable without occurrence of graft-versus-host disease. To investigate the relationship between the number and types of mismatches and relapse, we compared the number of mismatched and non-mismatched donor-recipient pairs, number of mismatched alleles, and number of mismatched antigens at each of the Human Leukocyte Antigen (HLA) -A, -B, and -DR loci, respectively...

Umbilical cord blood transplantation with a reduced-intensity conditioning regimen (RIC-UCBT) is used increasingly in patients who have comorbid organ functions and lack human leukocyte antigen-identical donors. We compared the outcomes in 35 patients who received mycophenolate mofetil plus cyclosporine (MMF/CSP, n = 17) or MMF plus tacrolimus (MMF/TAC, n = 18) for graft-versus-host disease (GVHD) prophylaxis after RIC-UCBT. Cumulative incidence of neutrophil engraftment was 94 and 89 % in MMF/CSP and MMF/TAC groups, respectively (p = 0...

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the best therapeutic option for childhood high-risk acute leukemia. However, which donor source is optimal for children lacking an identical sibling remains unclear. To evaluate the clinical impact of donor source on allo-HSCT in childhood acute leukemia, we analyzed data from 577 children who underwent allo-HSCT after a myeloablative regimen during first or second complete remission from 2005 to 2012, using registry data of the Japan Society for Hematopoietic Cell Transplantation, and we compared outcomes of 7/8 to 8/8 HLA allelic-matched unrelated bone marrow transplantation (UR-BMT, n = 218) and 4/6 to 6/6 HLA allelic-matched unrelated cord blood transplantation (UR-CBT, n = 200) to those of HLA-identical related bone marrow transplantation (ID-BMT, n = 159)...

BACKGROUND AND AIMS: Thalassemia is curable by bone marrow transplantation; however, finding suitable donors with defined HLA combination remains a major challenge. Cord blood stem cells with preselected HLA system through preimplantation genetic diagnosis (PGD) proved very useful for resolving scarce HLA-matched bone marrow donors. METHODS: A thalassemia trait couple with an affected child was included in this study. We used informative STR markers at the HLA and beta globin loci to develop a single cell multiplex fluorescent PCR protocol...

Graft-versus-host disease-free, relapse-free survival, which is defined as the absence of grade III-IV acute graft-versus-host disease, systemically treated chronic graft-versus-host disease, relapse, and death, is a novel, meaningful composite endpoint for clinical trials. To characterize risk factors and differences in graft-versus-host disease-free, relapse-free survival according to a variety of graft sources, we analyzed 23,302 patients with hematological malignancy who had a first allogeneic transplantation from 2000 through 2013 using the Japanese national transplant registry database...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...
