In recent years, vancomycin-resistant Enterococcus (VRE) colonization is increasingly being encountered among transplant populations, and VRE has become one of the leading causes of bacteremia early after allogeneic hematopoietic stem cell transplantation (allo-HSCT). There are sparse data regarding the effect of empiric VRE therapy for febrile, neutropenic allo-HSCT recipients colonized with VRE. All allo-HSCT patients aged 18 years and older who developed VRE bacteremia (VREB) between 2005-2014 were identified and categorized as to whether they received empiric versus (vs) directed VRE therapy...

Previous studies have reported single B cell related chronic graft-versus-host disease diagnostic (cGvHD) biomarkers such as B cell activating factor (BAFF), CD21low and immature B cells, but research on the performance of biomarker combinations and the covariate effect of steroids is lacking. The primary objective of this study was to determine the most accurate combination of B cell populations using cell surface staining flow cytometry in an independent cGvHD cohort. Secondary objectives included assessing the effect of corticosteroid use at sample collection on the make-up and accuracy of the diagnostic panel and identifying the mechanism underlying low surface expression of BAFF receptor (BAFF-R) on B cells in cGvHD...

There are limited data on whether to adjust high-dose chemotherapy prior to autologous hematopoietic cell transplant (autoHCT) in obese patients. This study explores the effects of dose adjustment on the outcomes of obese patients, defined as body mass index (BMI) ≥ 30 kg/m2 . Dose adjustment was defined as a reduction in standard dosing of ≥ 20%, based on ideal, reported dosing and actual weights. We included two groups of US patients who had received autoHCT between 2008 and 2014. Specifically, we included patients with multiple myeloma (MM, n=1696) treated with high-dose melphalan; and we included patients with Hodgkin or non-Hodgkin lymphomas (n=781) who received carmustine, etoposide, cytarabine, and melphalan (BEAM) conditioning...

The development of reduced intensity approaches for allogeneic hematopoietic cell transplantation has resulted in growing numbers of older related donors (RD) of PBSC. The effects of age on donation efficacy, toxicity, and long-term recovery in RD are poorly understood. To address this we analyzed hematologic variables, pain, donation-related symptoms and recovery in 1211 related PBSC donors aged 18-79 enrolled in the Related Donor Safety Study (RDSafe). RD >60 had a lower median CD34+ level pre-apheresis compared to younger RD (age >60, 59 × 106 /L; age 41-60, 81 × 106 /L; age 18-40, 121 × 106 /L; p<0...

Conventional cytogenetic analyses and fluorescent in situ hybridization (FISH) are helpful for stratifying patients with multiple myeloma (MM) into high-risk [t(4;14), t(14;16), and/or del 17p] and standard-risk [t(11;14)] categories. However, the prognosis of patients with MM treated with autologous stem cell transplantation (ASCT) stratified according to these categories remains unclear. This retrospective observational study analyzed 97 patients with MM who received a single, planned ASCT after treatment with 200 mg/m2 melphalan between 2001 and 2011...

Adoptive immunotherapy has shown efficacy in patients with relapsed/refractory AML. We conducted a prospective evaluation of Cord Blood-based adoptive cell therapy following salvage chemotherapy in patients (pts) with AML/MDS and describe the safety and early outcomes of this approach. To enhance the anti-leukemic effect we selected Cord Blood Units (CBU) with shared Inherited Paternal Antigens (IPA) and/or Non-Inherited Maternal Antigens (NIMA) match with the recipients. Further, CBU had Total Nucleated Cell (TNC) dose < 2...

Cord blood (CB) is an alternative stem cell source for allogeneic haematopoietic stem cell transplantation (HSCT). The unique advantages with CB as a stem cell source lies in a degree of permissibility for human leukocyte antigen (HLA) mismatch, rapid availability, and relatively risk-free cell collection. Since HLA is highly polymorphic and population specific, optimal HLA matched unrelated donors or cord blood units (CBUs) may not be available. In view of the chance that matched CBUs which include non-inherited maternal antigens (NIMA) might contain acceptable HLA mismatches, we attempted to determine the degree of allo-reactivity of CB mononuclear cells (MNC) upon stimulation by the maternal, paternal and unrelated stimulator cells...

Disruption of the intestinal microbiome early after allogeneic hematopoietic cell transplantation (allo-HCT) has been linked to adverse outcomes in transplant recipients. To date, it remains unknown as to whether microbiome-directed interventions will be able to impact important clinical endpoints. Fecal microbiota transplantation (FMT) is a compelling intervention to restore healthy diversity to the intestinal microenvironment after allo-HCT, but currently has no established role in transplant recipients. In this review, we examine the utilization of FMT as treatment for Clostridium difficile infections and acute graft-versus-host disease, as well as a restorative intervention early after allo-HCT...

Effective therapies for treating patients with steroid-refractory acute graft-versus-host-disease (SR-aGvHD), particularly strategies that reduce the duration of immunosuppression following remission, are urgently needed. The investigated immunotoxin-combination consists of a mixture of anti-CD3 and anti-CD7 antibodies separately conjugated to recombinant ricin A (CD3/CD7-IT), which induces in-vivo depletion of T- and NK-cells and suppresses T-cell receptor activation. We conducted a phase I/II trial in order to examine the safety and efficacy of CD3/CD7-IT in 20 patients with SR-aGvHD; 17 of these patients (85%) had severe SR-aGvHD, and all 20 patients had visceral organ involvement; 18 gastrointestinal (GI) (90%) and 5 liver (25%) involvement...

We previously reported in a French prospective randomized study that transplantation of 2 unrelated cord blood (UCB) units instead of 1 does not decrease the risk of transplantation failure but may enhance alloreactivity. We present here the influence of pre-transplant minimal residual disease (MRD) on leukemia relapse and survival after single versus double-UCB transplantation. Among 137 children and young adults who were transplanted in the randomized study, 115 had available MRD assessment immediately before their conditioning regimen...

Innate immune cells are the first to recover after allogeneic hematopoietic cell transplantation (HCT). Nevertheless, reports of innate immune cell recovery and their relation to adaptive recovery after HCT are largely lacking. Especially predicting CD4+ T cell reconstitution is of clinical interest, because this parameter directly associates with survival chances after HCT. We evaluated whether innate recovery relates to CD4+ T cell reconstitution probability and investigated differences between innate recovery after cord blood transplantation (CBT) and bone marrow transplantation (BMT)...

Owing to the difficulty in isolating T cells from human biopsy samples, the characteristics of T cells that are infiltrating human acute graft-versus-host disease (GVHD) tissues remain largely uninvestigated. In the present study, TCR-β deep sequencing of various GVHD tissue samples and concurrent peripheral blood obtained from transplant recipients was performed in combination with functional assays of tissue-infiltrating T cell clones. The T cell repertoire was more skewed in GVHD tissues than in the peripheral blood...

Viral infection is a serious complication that can greatly affect patient mortality and morbidity after allogenic hematopoietic stem cell transplantation (allo-HSCT). For the early identification of patients at high risk for viral infection, we evaluated the impact of lymphocyte area under the curve (AUC) value as a new predictive factor for early immune reconstitution after allo-HSCT against viral infection. This study included 286 patients who underwent their first allo-HSCT at Kyoto University Hospital between 2005 and 2017...

Human cytomegalovirus (CMV) infection and disease remains a significant cause of morbidity and mortality for hematopoietic cell transplantation (HCT) recipients. Disruption of or weak reconstitution of virus-specific cellular immune function, such as with certain HCT approaches, poses significant risk for CMV-related complications. The incidence of and risk factors for CMV infection and the nature of CMV disease were evaluated retrospectively among 356 consecutive HCT recipients transplanted at the National Institutes of Health using all graft sources, including bone marrow, peripheral blood stem cell (PBSC), and umbilical cord blood (UCB), and a range of in vivo and ex vivo approaches for graft-versus-host disease (GVHD) prophylaxis...

Graft-versus-host disease (GVHD) remains a significant challenge in allogeneic hematopoietic cell transplantation (HCT). An underinvestigated strategy to reduce GVHD is the modification of the preparative conditioning regimen. In the present study, we aimed to evaluate GVHD associated with bendamustine (BEN) conditioning in conjunction with total body irradiation (TBI) as an alternative to the standard myeloablative regimen of cyclophosphamide (CY) and TBI. We demonstrate that BEN-TBI conditioning, although facilitating complete donor chimerism, results in significantly less GVHD compared with CY-TBI...
