A xenograft model of stem cell rejection was developed by co-transplantating human CD34+ and allogeneic CD3+ T cells into NOD-scid ɣ-chain(null) (NSG) mice. T cells caused graft failure when transplanted at any CD34:CD3 ratio between 1:50 to 1:0.1. Kinetics experiments showed that two weeks after transplantation CD34+ cells engrafted the marrow and T cells expanded in the spleen. Then at four weeks only memory T cells populated both sites and rejected CD34+ cells. Blockade of T cell costimulation was tested by injecting the mice with abatacept (CTLA4-IgG1) from day -1 to +27 (Group A), or from day -1 to +13 (Group B), or from day +14 to +28 (Group C)...

Graft-versus-host disease (GvHD) remains one of the major complications after allogeneic hematopoietic stem cell transplantation which is mainly treated with glucocorticoids such as prednisolone. In this study, the influence of monocyte subpopulations, prednisolone and 1α,25-Dihydroxyvitamin D3 on the induction of a pro-inflammatory subset of Th17 cells (MDR(+)Th17.1) characterized by CCR6(+)CXCR3(hi)CCR4(lo)CCR10(-)CD161(+) and stable expression of the multi-drug resistance protein type 1 (MDR1) was investigated...

Busulfan (Bu) is a key component of conditioning regimens used prior to hematopoietic stem cell transplantation (SCT) in children. Different predictive methods have been used to calculate the Bu first-dose. To evaluate the necessity of further improvements, we retrospectively analyzed the currently available weight- and age-based guidelines to calculate the first doses in 101 children who underwent allogenic SCT in CHU Sainte-Justine, Montreal, following an intravenous Bu-containing conditioning regimen according to genetic and clinical factors...

High risk, recurrent, or refractory solid tumors in pediatric, adolescent and young adult (AYA) patients have an extremely poor prognosis despite current intensive treatment regimens. We piloted an allogeneic bone marrow transplant (alloBMT) platform using a reduced intensity conditioning (RIC) and partially HLA-mismatched (haploidentical) related donors for this population of pediatric and AYA solid tumor patients. Sixteen patients received a fludarabine, cyclophosphamide (Cy), melphalan and low dose total body irradiation (TBI) RIC haploidentical BMT (haploBMT) followed by post-transplantation cyclophosphamide (PTCy), mycophenolate mofetil (MMF) and sirolimus...

The European Group for Blood and Marrow Transplantation (EBMT) risk score has been implemented as an important tool to predict patient outcomes following allogeneic haematopoietic stem cell transplantation (allo-HSCT). However, to our knowledge, this score has never been applied in cases of single umbilical cord blood transplantation (sUCBT). We retrospectively analyzed 207 consecutive patients with acute leukemia who received sUCBT at our centre between February 2011 and December 2015. The probability of 3-year overall survival (OS) and leukemia-free survival (LFS) of the entire cohort were 65...

Infection-related mortality (IRM) accounts for a substantial component of non-relapse mortality (NRM) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). No scores have been developed to predict IRM before transplant. Pre-transplant clinical and biochemical data were collected in a study cohort of 607 adult patients receiving allo-HSCT from January 2009 to February 2017. In a training set of 273 patients, multivariate analysis revealed that age >60 years (P=0.003), CMV host/donor serostatus different from negative/negative (P<0...

Granulocyte transfusions (GTs) are seldom used as a life-saving therapy for neutropenic patients with severe infections. Despite several compelling evidences of GT efficacy in retrospective and prospective case series, no study has been successful in demonstrating a definite advantage for recipients in controlled clinical trials. This review will critically revise some aspects emerging from the past experience which might have weakened the evidence of GT benefits. Some specific issues relevant to the efficacy of this therapeutic approach, such as the primary infection, the delivered doses and schedules, and the immunological effects of GTs, will be discussed...

Improvements in supportive care have enabled allogeneic hematopoietic cell transplant (HCT) to be performed in increasingly older patients. HCT is associated with neurocognitive impairment, which may be exacerbated in older adults due to normal neurocognitive decline associated with aging. The goal of this study was to evaluate whether increased age in allogeneic HCT recipients is associated with worse neurocognitive outcomes over time relative to a matched sample of individuals without cancer. Patients (n = 140; 42% female, M age = 51, range = 20-76; 31% with acute myeloid leukemia) completed neurocognitive assessments before transplant and three months and one year post-transplant...

Autologous hematopoietic stem cell transplantation (Auto- HSCT) improves survival in multiple myeloma (MM) and Non-Hodgkin lymphoma (NHL). Traditionally, filgrastim (Neupogen® - recombinant G-CSF) has been used in as a single agent or in combination with plerixafor for stem cell mobilization for auto-HSCT. In Europe, recombinant G-CSF biosimilar (Tevagrastim®) is approved for various indications similar to reference filgrastim, including stem cell mobilization for auto-HSCT; However, tbo- Filgrastim (Granix®) is registered under original biologic application and is not approved for stem cell mobilization in the USA...

Predicting the duration of systemic therapy in patients with chronic graft-versus-host disease (cGVHD) is of critical clinical importance when counseling patients and for treatment planning. CGVHD characteristics associated with this outcome have not been studied in severely affected patients. The National Institutes of Health (NIH) cGVHD scoring provides a standardized set of organ severity measures which could represent clinically useful and reproducible predictive characteristics. We analyzed 227 previously treated patients most with moderate (n=54) or severe (n=170) cGVHD defined by NIH criteria who were prospectively enrolled in a natural history protocol (NCT00092235)...

Allogeneic hematopoietic stem cell transplantation is a potentially curative treatment for many hematologic disorders. Maximizing the benefit of transplantation for disease control while minimizing the risk for associated complications remains the field's leading challenge. This has prompted the development of multiple prognostic scoring systems over the last two decades. Prognostic scores can be used for informed decision making, better patient counseling, design of interventional trials and analysis of prospective and retrospective data...

Recognizing the significant biologic and clinical heterogeneity of mature T-cell and NK/T-cell lymphomas, the American Society for Blood and Marrow Transplantation invited experts to develop clinical practice recommendations related to the role of auto-HCT and allo-HCT for specific histologic subtypes. We used the GRADE methodology to assist in moving from evidence to decision-making and ultimately generating final recommendations. Auto-HCT in front-line consolidation is recommended in PTCL-NOS, AITL, ALCL-ALK negative, NK/T-cell (disseminated), EATL and hepatosplenic lymphomas...

Cord blood transplantation (CBT) from HLA-identical sibling is an attractive option for patients with bone-marrow-failures syndromes (BMF), due to the low risk of graft-versus-host disease (GVHD) and the absence of risk to the donor. We analyzed outcomes of 117 patients with inherited or acquired BMF, who received CBT from a related HLA-identical donor in EBMT centers, between 1988 and 2014. Ninety-seven patients had inherited and 20 patients acquired BMF. Eighty-two patients received a single cord blood (CB) unit, whereas 35 patients received a combination of CB and bone marrow (BM) cells from the same donor...

Opportunistic infections such as cytomegalovirus (CMV) reactivation and invasive fungal disease (IFD) cause significant morbidity and mortality to recipients of hematopoietic stem cell transplant (HSCT). We aimed to characterise the risk and relationship of CMV reactivation post-HSCT to IFD in the current era of CMV viral load monitoring using highly sensitive plasma DNA. A multi-centre retrospective cohort study was conducted of consecutive patients undergoing allogeneic HSCT from January 2006 to December 2010 in Melbourne, Australia...

This study aimed to ascertain unmet needs in autologous and allogeneic HCT recipients actively followed in an established long-term survivorship clinic at Roswell Park Cancer Institute from 2006-2012. The Survivor Unmet Needs Survey (SUNS) was mailed to 209 eligible patients and returned by 110 (53% participation rate). SUNS includes 89-items covering 5 domains: Emotional Health, Access and Continuity of Care, Relationships, Financial Concerns, and Information. The top five specific unmet needs for autologous HCT patients were: inability to set future goals/long-term plans; changes in appearance; bad memory/lacking focus; losing confidence in abilities; paying household or other bills...

Idiopathic pneumonia syndrome (IPS) is a complication of allogeneic hematopoietic stem cell transplantation (HSCT) that typically occurs within the first 100 days after transplantation. Tumor necrosis alpha-α (TNF-α) has been shown to be a key mediator of IPS, and the TNF-α binding protein, etanercept, appears to improve IPS outcomes in small retrospective and prospective studies. IPS has also been observed to occur later (>100 days) after HSCT; however, little is known about the disease course and whether a TNF-α-based therapeutic strategy is efficacious in these patients...

Clinical manifestation of high grade fever and skin rash prior to neutrophil engraftment, which is called pre-engraftment syndrome (PES) or pre-engraftment immune reaction, has been frequently observed after cord blood transplantation (CBT). The pathophysiology of PES is poorly understood, but cytokine storm during the early phase of CBT is thought to be one of the main cause of PES. However, the cytokine profiles of PES after CBT are unclear. Therefore, we examined the relationship between serum cytokine profiles and PES in 44 adult patients who received CBT in our institute between February 2013 and June 2016...

High-dose melphalan (HDM) and autologous blood stem cell transplantation (ABSCT) is an effective treatment for transplant-eligible patients with systemic light chain (AL) amyloidosis. Whereas most centers use granulocyte colony-stimulating factor (G-CSF) alone for mobilization of peripheral blood stem cells (PBSC), the application of mobilization chemotherapy might offer specific advantages. We retrospectively analyzed 110 patients with AL amyloidosis who underwent PBSC collection. Major eligibility criteria included age <70 years and cardiac insufficiency NYHA ≤III°...
