BACKGROUND AIMS: Acute graft-versus-host disease (aGVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation, mediated by alloreactive donor T cells. Toll-like receptors (TLRs), a family of conserved pattern-recognition receptors (PRRs), represent key players in donors' T-cell activation during aGVHD; however, a regulatory, tolerogenic role for certain TLRs has been recognized in a different context. We investigated whether the ex vivo-induced TLR-2,-4,-7 tolerance in donor cells could prevent alloreactivity in a mismatched transplantation model...

Use of high-dose, post-transplant cyclophosphamide (PTCy) results in low rates of graft-versus-host-disease (GVHD) and favorable immune reconstitution, although with higher rates of relapse and somewhat high rates of graft failure. We hypothesized that permissible dose reduction of PTCy might be feasible. The current study attempts to establish a murine model and focus on regulatory T cells (Tregs) to clarify the immunological mechanisms for GVHD prevention by low-dose PTCy. In addition, a prospective, clinical cohort study in haploidentical, T-cell replete transplantation is initiated to support the rational...

Patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) were given the option to be treated at home during the pancytopenic phase. Daily visits by a nurse and phone calls from a physician from the unit were part of the protocol. During almost two decades, 252 patients with haematological malignancies and non-malignant disorders were included. Median age was 47 (range 0-72) years. Myeloablative conditioning was given to 102 patients and reduced intensity to 150. Donors were matched unrelated (n = 160), HLA-identical siblings (n = 71), or HLA-mismatched (n = 21)...

Autologous, patient-specific chimeric antigen receptor T-cell (CART) therapy has emerged as a powerful and potentially curative therapy for cancer, especially for CD19-positive hematological malignancies. Indeed, on August 30, 2017, the University of Pennsylvania-designed CD19-directed CART (CART-19) cell therapy (CTL019, tisagenlecleucel-t, Kymriah - Novartis) became the first CART therapy approved by the Food and Drug Administration (FDA) for acute lymphoblastic leukemia. However, the development of CART technology and its wider application is partly limited by the patient-specific nature of such a platform and by the time required for manufacturing...

Despite detailed human leukocyte antigen (HLA) matching and modern immunosuppressive therapy, severe graft-versus-host disease (GvHD) remains a major hurdle for successful allogeneic hematopoietic stem cell transplantation (HSCT). As the genetic diversity in GvHD complicates the systematic discovery of associated variants across populations, we studied 122 GvHD-associated single nucleotide polymorphisms (SNPs) in 492 HLA-matched sibling HSCT donor-recipient pairs from Finland and Spain. The association between these candidate SNPs and grade III-IV acute GvHD and extensive chronic GvHD was assessed...

BACKGROUND: Growing numbers of allogeneic stem cell transplants (HSCT) and improved post-transplant care have led to an increase of individuals with chronic graft versus host disease (cGVHD). Although cGVHD leads to functional impairment for many, there is limited literature regarding the benefits of acute inpatient rehabilitation for cGVHD patients. OBJECTIVE: To assess Functional Independence Measure (FIM) outcomes of cGVHD patients during acute inpatient rehabilitation, and to compare inpatient rehabilitation outcomes to burn patients, a rehabilitation patient population with similar co-morbidities...

Plasmacytoid dendritic cells (pDCs) promote tolerance in solid organ transplants and hematopoietic stem cell transplantation (HSCT). pDCs originate from CD34(+) hematopoietic progenitors. Following allogeneic hematopoietic stem cell transplant (allo-HSCT), pDC reconstitution in the BM and PB gradually attain levels similar to those in healthy individuals. We have investigated the recovery of pDC following allo-HSCT as a means to predict successful marrow engraftment. We retrospectively studied immune reconstitution of pDC in the BM of 48 patients following allo-HSCT for initial diagnoses of leukemia or other malignancies...

The mammalian target of rapamycin (mTOR) inhibitor rapamycin (RAPA) has been shown to be an effective immunosuppressor in the management of acute graft-versus-host disease (aGVHD) after bone marrow transplantation. Myeloid-derived suppressor cells (MDSCs) also have a protective effect in aGVHD regulation. However, the relationship between RAPA and MDSCs in aGVHD models is unclear. Meanwhile, the effect of RAPA on different subgroups of MDSCs is also less well described. In this study, we demonstrate that in vivo administration of RAPA results in the expansion and functional enhancement of polymorphonuclear MDSCs (PMN-MDSCs) in a murine model of aGVHD...

Graft-versus-Host Disease (GvHD) is a prevalent and potentially lethal complication of hematopoietic stem cell transplantation (HSCT). Humanized mouse models of xenogeneic-GvHD are important tools used to study the human immune response in vivo. Here we used NOD-scid IL-2Ry(null) mice (NSG) transplanted with human bone marrow stem cells to evaluate the role of immune cell engraftment in the production of acute GvHD. PRO 140, a humanized monoclonal antibody targeting the chemokine receptor, CCR5, was used to evaluate its influence on bone marrow cell engraftment and modulation of acute GvHD...

The risk of acute graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation is increased with donor-recipient HLA-DPB1 allele mismatching. The single-nucleotide polymorphism (SNP) rs9277534 within the 3' untranslated region (UTR) correlates with HLA-DPB1 allotype expression and serves as a marker for permissive HLA-DPB1 mismatches. Since rs9277534 is not routinely typed, we analyzed 32,681 samples of mostly European ancestry to investigate if the rs9277534 allele can be reliably imputed from standard DPB1 genotyping...

Antigen-specific regulatory T cells (Tregs) possess the potential to reduce excess immune responses in autoimmune diseases, allergy, rejection after organ transplantation, and graft-versus-host disease (GVHD) in hematopoietic stem-cell transplantation. Although in vitro-expanded antigen-specific induced Tregs (iTregs) have been considered to be a promising therapeutic agent against such excessive immune reactions, the instability of iTregs after transfer is a fundamental problem in their clinical application...

PURPOSE OF REVIEW: Purine nucleosides and nucleotides are released in the extracellular space following cell injury and act as paracrine mediators through a number of dedicated membrane receptors. In particular, extracellular ATP (eATP) significantly influences T-lymphocyte activation and phenotype. The purpose of this review is to discuss the role of ATP signaling in the T-cell-mediated alloimmune response. RECENT FINDINGS: In various animal models of solid transplantation, the purinergic axis has been targeted to prevent acute rejection and to promote long-term graft tolerance...

BACKGROUND: In a previously published study, the authors randomized 108 adult patients with a malignant hematologic disorder undergoing allogeneic bone marrow transplantation from a human leukocyte antigen-identical sibling to receive methylprednisolone (53 patients; MP+) or not to receive methylprednisolone (55 patients; MP-) as a part of graft-versus-host disease (GVHD) prophylaxis. All patients received cyclosporine and methotrexate. The cumulative incidence of acute GVHD was found to be significantly lower among the patients given MP...

Influenza infection and Pneumocystis jirovecii pneumonia (PJP) in hematopoietic stem cell transplant (HSCT) patients are well characterized, however no dual infections have been reported in this patient population and little evidence of mechanisms of interaction between the two infections exists. We present a 53-year-old male allogeneic HSCT patient on immunosuppressive therapy for the treatment of graft-versus-host disease initially diagnosed with influenza A H3, and later PJP. Despite the development of acute respiratory distress syndrome, the patient was successfully treated with appropriate antimicrobial therapy and aggressive supportive care...

The medical records of 44 pediatric patients who underwent allogeneic transplantation from 2011 to 2015 were retrospectively reviewed. Magnetic resonance imaging was used to measure iron concentrations in the liver, spleen, pancreas and bone. These patients were divided into two groups, 18 with non-elevated (< 100 μmol/g; Group 1) liver iron concentration before transplantation and 26 with elevated (> 100 μmol/g; Group 2) concentration . We compared transplant-related outcomes in the two groups. Iron overload was a negative prognostic risk factor for sinusoidal obstruction syndrome (OR = 17), osteoporosis (OR = 6...

Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). At our Institution, patients transplanted using G-CSF-primed bone marrow (G-BM), have a lower incidence of GVHD when compared to other sources. The objective of this study was to analyze and compare T cell subsets and cytokines in donor G-BM and steady-state BM (SS-BM). A prospective study was performed in 48 donor samples. Mononuclear cells were isolated by gradient density. T cell subsets and cytokine production in supernatants were analyzed by multiparametric flow cytometry...

No standard exists for the treatment of myelodysplastic syndrome relapsing after allogeneic stem cell transplantation. We performed a retrospective registry analysis of outcome and risk factors in 698 patients, treated with different strategies. Median overall survival from relapse was 4.7 months (4.1-5.3), 2-year survival was 17.7% (14.8-21.2%). Shorter remission after transplantation (p<0.001), advanced disease (p=0.001), older age (p=0.007), unrelated donor (p=0.008) and acute Graft-versus-Host disease before relapse (p<0...

Acute graft-versus-host disease (aGVHD) is a significant cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). Due to the poor prognosis for patients not responding to first-line steroids treatment, improvements in aGVHD therapy are needed. Everolimus is a promising candidate that combines immunosuppressive properties with anti-neoplastic effects. Here, we retrospectively reviewed the efficacy of everolimus with steroids as primary treatment in 13 patients with grade II to grade IV aGVHD after HSCT...

The outcomes of adult patients transplanted for Fanconi anaemia (FA) have not been well described. We retrospectively analysed 199 adult patients with FA transplanted between 1991 and 2014. Patients were a median of 16 years of age when diagnosed with FA, and underwent transplantation at a median age of 23 years. Time between diagnosis and transplant was shortest (median 2 years) in those patients who had a human leucocyte antigen identical sibling donor. Fifty four percent of patients had bone marrow (BM) failure at transplantation and 46% had clonal disease (34% myelodysplasia, 12% acute leukaemia)...
