Allogeneic stem cell transplantation (SCT) from an HLA-matched sibling donor (MSD) is a post-remission treatment that offers a potential cure for adults with cytogenetically normal acute myeloid leukemia in their first complete remission (CN-AML/CR1). However, the best alternative in the absence of an MSD remains unclear. The aim of this study was to retrospectively compare the outcomes of autologous peripheral blood stem cell transplantation (auto-PBSCT; n = 177) to those of allogeneic bone marrow transplantation from an HLA-matched unrelated donor (MUD-BMT; n = 173) in adult patients with CN-AML/CR1...

Patients with inherited bone marrow failure syndromes (IBMFS) such as Fanconi anemia (FA), dyskeratosis congenita (DC), and Diamond Blackfan anemia (DBA) can have hematologic manifestations cured through hematopoietic cell transplantation (HCT). Subsequent late effects seen in these patients arise from a combination of the underlying disease, the pre-HCT therapy, and the HCT process. During the international consensus conference sponsored by the Pediatric Blood and Marrow Transplant Consortium entitled "Late Effects Screening and Recommendations Following Allogeneic Hematopoietic Cell Transplant for Immune Deficiency and Nonmalignant Hematologic Disease" held in Minneapolis, Minnesota in May of 2016, a half-day session was focused specifically on the unmet needs for these patients with IBMFS...

Clinical islet transplantation is an effective therapy in restoring physiological glycemic control in type 1 diabetics. However, allogeneic islets derived from cadaveric sources elicit immune responses that result in acute and chronic islet destruction. To prevent immune destruction of islets, transplant recipients require lifelong delivery of immunosuppressive drugs, which are associated with debilitating side effects. Biomaterial-based strategies to eliminate the need for immunosuppressive drugs are an emerging therapy for improving islet transplantation...

Bone marrow derived mesenchymal stem cells (MSCs) play a critical role in immune modulation. However, immunomodulatory function of whole human umbilical cord derived mesenchymal stem cells (UC-MSCs) remains unclear. In this study, UC-MSCs were separated from whole umbilical cord using a single enzyme digestion. UC-MSCs (CD73(+), CD90(+), CD105(+), and CD34(-), CD45(-), HLA-DR(-)) were differentiated into adipocytes, osteocytes and chondrocytes in vitro under specific stimulatory environments. UC-MSCs suppressed umbilical cord blood lymphocyte proliferation stimulated by mitogen, and ELISA showed that the secretion of INF-γ was downregulated, and the secretion of IL-4 was upregulated, with CD8(+) T cells markedly decreased and CD4(+) T cells changed lightly...

Graft-versus-host disease (GVHD) remains a significant potentially life-threatening complication of allogeneic hematopoietic cell transplantation (HCT). Since the discovery of the human leukocyte antigen (HLA) system over 50 years ago, significant advances have clarified the nature of HLA variation between transplant recipients and donors as a chief etiology of GVHD. New information on coding and non-coding gene variation and GVHD risk provides clinicians with options to consider selected mismatched donors when matched donors are not available...

Rationale: Patients receiving an allogeneic stem cell graft from cytomegalovirus (CMV) seronegative donors are particularly prone to CMV reactivation with a high risk of disease and mortality. Therefore we developed and manufactured a novel vaccine and initiated a clinical phase I trial with a CMV phosphoprotein 65 (CMVpp65)-derived peptide. Methods: Ten patients after allogeneic stem cell transplantation received four vaccinations at a biweekly interval. All patients were monitored for CMVpp65 antigenemia...

INTRODUCTION: Most common source of stem cell graft for both autologous and allogenic haematopoietic transplants are peripheral blood haematopoietic progenitor stem cells. Adequate collection of the CD34+ cells and safety of the allogenic donor during the leukapheresis are of prime importance to an apheresis physician. Our retrospective analysis is a comparison between of two platforms namely, COBE Spectra and Amicus, for CD34+ mononuclear cell collection. MATERIAL AND METHOD: The study included the data of GSCF (Granulocyte-Colony-Stimulating Factor) mobilized allogenic PBSC collections at our centre from January 2015 to June 2016...

In patients with relapsed or refractory (r/r) AML, allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is considered to be the only treatment providing long-term disease control. The BRIDGE trial studied the safety and efficacy of a clofarabine-based salvage therapy prior to HSCT in patients with r/r AML. Here, we report the long-term follow up of this Phase II, multi-center trial and exploratory analyses on the impact of comorbidity on outcome. Eighty-four patients with a median age of 61 years (range 40 - 75) were enrolled...

Patients with chronic myeloid leukemia (CML) have a t (9;22)(q34;q11.2) or variant translocation that results in a BCR-ABL1 fusion gene. For many years, conventional karyotyping has been used as the standard diagnostic tool for t (9;22) (q34;q11.2). However, it has several limitations that may lead to failure for detecting BCR-ABL1 gene rearrangements in around 5% of all CML patients. Although reverse transcription polymerase chain reaction (RT-PCR) has evolved as a sensitive method for detecting BCR-ABL1 translocation, this method fail to detect certain BCR-ABL1 fusion transcript type, such as e13a3 (also known as b2a3), as a result of many commercially available and laboratory-developed primer sets...

The cure of acute leukemia by allogeneic hematopoietic stem cell transplantation (allo-HSCT) is closely linked to major complications leading to adverse outcomes, including graft-versus-host disease (GVHD), disease relapse and death. This study retrospectively investigated a consecutive series of 312 adult patients with acute leukemia receiving allo-HSCT by using a novel concept of GVHD-free/relapse-free survival (GRFS), and further evaluated the impact of clinical factors on GRFS. Results indicated that the 1- and 2-year GRFS were 54...

BACKGROUND: Acute graft-versus-host disease (aGVHD) is a common and severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Some studies have found that the presence of certain specific human leukocyte antigen (HLA) loci could affect the occurrence of aGVHD. Meanwhile, the impact of HLA haplotypes on aGVHD has been rarely studied. This study aimed to investigate the effects of HLA loci and haplotypes on intestinal aGVHD. METHODS: Totally, 345 consecutive patients undergoing first HLA-matched sibling peripheral blood stem cell transplantation (PBSCT) from February 2004 to June 2013 at Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, were enrolled in this study...

In the general population, older age is associated with short leukocyte telomere length and with high risk of infections. In a recent study of allogeneic hematopoietic cell transplantation for severe aplastic anemia, long donor leukocyte telomere length was associated with improved survival in the recipients. These findings suggest that leukocyte telomere length could possibly be a marker of immune competence. Therefore, we tested the hypothesis that shorter leukocyte telomere length is associated with higher risk of infectious disease hospitalization and infection related death...
