BACKGROUND: A risk score identifying patients at high risk for veno-occlusive disease (VOD) may aid efforts to study preventive strategies for this uncommon complication of hematopoietic cell transplantation (HCT). METHODS: Patients receiving a first allogeneic HCT between 2008-2013 as reported to the Center for International Blood & Marrow Transplant Research (N=13,097) were randomly divided into training and validation sets. Independent prognostic factors for development of VOD by day+100 post HCT were identified with a multivariate logistic regression model...

PURPOSE: Total-body irradiation (TBI) is a major constituent of myeloablative conditioning regimens. The standard technique consists of 12Gy in 6 fractions over 3 days. The SARASIN study aimed to compare standard-fractionation to one-daily fractionation prior to transplant in leukemia. MATERIAL AND METHODS: We retrospectively compared TBI regimens delivered in 2993 patients from the EBMT database, transplanted between 2000 and 2014 for acute lymphoblastic (ALL, n=1729) or acute myelogenous (AML, n=1264) leukemia...

OBJECTIVE/BACKGROUND: Clostridium difficile infection (CDI) is a potential complication during hematopoietic stem cell transplantation (HSCT), and no specific recommendations exist regarding treatment of CDI in allogeneic SCT patients. Use of metronidazole and oral vancomycin has been associated with clinical failure. Fidaxomicin has previously been found noninferior to the use of oral vancomycin for the treatment of CDI, and no studies have compared the use of oral vancomycin with fidaxomicin for the treatment of CDI in allogeneic SCT...

Hematopoietic cell transplantation (HCT) is widely performed for neoplastic and non-neoplastic diseases. HCT involves intravenous infusion of hematopoietic progenitor cells from human leukocyte antigen (HLA)-matched donor (allogeneic) or from the patient (autologous). Before HCT, the patient is prepared with high dose chemotherapy and/or radiotherapy to destroy residual malignant cells and to reduce immunologic resistance. After HCT, chemotherapy is used to prevent graft rejection and graft versus host disease (GvHD)...

Allogeneic organ transplants are rejected by the recipient immune system within several days or weeks. However, the rejection process of allogeneic T (allo-T) cells is poorly understood. In this study, using fluorescence-based monitoring and two-photon live imaging in mouse adoptive transfer system, we visualized the fate of allo-T cells in the in vivo environment and showed rapid elimination in secondary lymphoid organs (SLOs). Although i.v. transferred allo-T cells efficiently entered host SLOs, including lymph nodes and the spleen, ∼70% of the cells had disappeared within 24 h...

To study the factors associated with poorer health-related quality of life at 1-year post-allogeneic hematopoietic cell transplantation (alloHCT), a secondary analysis of a prospective feasibility study was performed. Pediatric Quality of Life Inventory questionnaires were collected in 76 children undergoing alloHCT at baseline (within 30 d before transplantation), day 100, 6 months, and 12 months posttransplantation. The global score improved post-HCT (baseline: 67.1, 12 mo: 76.6). Females (odds ratio, 6...

We compared transplant outcomes between donor types and stem cell sources for childhood acute myeloid leukemia (AML). The medical records of children with AML in the Yeungnam region of Korea from January 2000 to June 2017 were reviewed. In all, 76 children with AML (male-to-female ratio = 46:30) received allogenic hematopoietic stem cell transplantation (allo-HSCT). In total, 29 patients received HSCT from either a matched-related donor or a mismatched-related donor, 32 patients received an unrelated donor, and 15 patients received umbilical cord blood...

Patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) are at high risk of readmission for complications. We sought to examine the association between HSCT hospital length of stay and the incidence of readmission and survival after discharge. We retrospectively reviewed the cases of 230 allo-HSCT recipients. The cumulative incidence of readmission with non-relapse transplant-related complications (including infections; acute and chronic GVHD; liver, lung, renal, or neurological complications; and haematological abnormalities) 2 years after the first discharge was 49...

REVIEW
Christoph Renner, Frank Stenner
Patients with classical Hodgkin lymphoma (cHL) have an impaired cellular immune response as indicated by an anergic reaction against standard recall antigens and a diminished rejection reaction of allogeneic skin transplant. This clinical observation can be linked to the histopathological feature of cHL since the typical pattern of a cHL manifestation is characterized by sparse large CD30+ tumor-infiltrating Hodgkin-Reed-Sternberg (HRS) cells that are surrounded by a dense inflammatory immune microenvironment with mixed cellularity...

Immunoglobulin G (IgG) fragment crystallizable (Fc) N -glycosylation has a large influence on the affinity of the antibody for binding to Fcγ-receptors (FcγRs) and C1q protein, thereby influencing immune effector functions. IgG Fc glycosylation is known to be partly regulated by genetics and partly by stimuli in the microenvironment of the B cell. Following allogeneic hematopoietic stem cell transplantation (HSCT), and in the presence of (almost) complete donor chimerism, IgG is expected to be produced by, and glycosylated in, B cells of donor origin...

To date, the only successful means of achieving allogeneic transplantation tolerance in the clinic has involved induction of mixed lymphohematopoietic chimerism. Such chimerism was first achieved in mice and subsequently in large animals, including miniature swine, monkeys and most recently humans. The mechanism of tolerance has differed between models, involving both deletional and regulatory mechanisms, in varying proportions, depending on the model. Considerable progress has also been made toward induction of tolerance across the xenogeneic pig-to-primate barrier, although complete success has not yet been achieved...

Chronic graft-versus-host disease (cGvHD) is a grave complication of allogeneic hematopoietic cell transplantation (alloHCT). Despite the use of prophylactic regimens for cGvHD, a significant proportion of patients develop cGvHD following alloHCT. The standard first-line therapy for cGvHD is high-dose corticosteroids. However, roughly 50% of patients will exhibit steroid-refractory or steroid-dependent cGvHD, which increases the risk of non-relapse mortality. Ibrutinib was approved by the U.S. Food and Drug Administration (FDA) in August 2017 for the treatment of cGvHD after failure of one or more lines of systemic therapy...

Intestinal graft-versus-host disease (GvHD) is a life-threatening, inflammatory donor T cell-mediated complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). In the light of the reported efficacy of interleukin-23 (IL-23)-blockade to mitigate syngeneic intestinal inflammation in inflammatory bowel disease patients, targeting IL-23 and thereby interleukin-17a (IL-17a) producing T helper (Th17) cells as the T cell subset assumed to be mostly regulated by IL-23, has emerged as a putatively general concept to harness immune-mediated mucosal inflammation irrespective of the underlying trigger...

iASPP is a negative regulator of the apoptotic function of p53, and it can enhance the ability of hematopoietic stem cells to self-renew and resist chemo- and radiation therapy. Recent study showed that iASPP could impact the proliferation and apoptosis of leukemia cells by interacting with FHL2. However, whether they have prognostic significance in acute myeloid leukemia (AML) is unknown. Eighty-four AML patients with FHL2 and iASPP expression data from The Cancer Genome Atlas database were enrolled in the study...

Bloodstream infection (BSI) is a well-known cause of morbidity and mortality in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Here, we conducted a retrospective study to assess the morbidity, etiology, risk factors, and outcomes of BSI in the post-engraftment period (PE-BSI) following allo-HSCT. Forty-three out of 316 patients (13.6%) developed 57 PE-BSI episodes, in which 62 pathogens were isolated: gram-positive bacteria, gram-negative bacteria, and fungi, respectively, accounted for 54...

Benign precursors of B lymphocytes, termed hematogones, are observed in the regenerative state of hematopoiesis following chemotherapy or allogeneic hematopoietic stem cell transplantation (allo-HSCT). Previous studies have demonstrated that expansion of hematogones correlates with better clinical outcomes after allo-HSCT. We retrospectively analyzed the association between hematogones and clinical outcomes in 309 consecutive patients undergone allo-HSCT, which was the largest population-based cohort reported so far...

Cytogenetic abnormalities are well-known and powerful independent prognostic factor for various hematological disorders. Although the combination of chemotherapy with tyrosine kinase inhibitor (TKI) is now considered the standard of care in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia, little is known about the impact of additional cytogenetic abnormalities (ACAs). Therefore, we retrospectively evaluated 1375 adult patients who underwent their first allogeneic hematopoietic stem cell transplantation in the TKI era...
