OBJECTIVES: We evaluated the safety and efficacy of 2 conditioning regimens (busulfan/fludarabine vs modified busulfan/cyclophosphamide) in patients with acute myeloid leukemia undergoing haploidentical hematopoietic stem cell transplant. MATERAILS AND METHODS: Twenty patients with primary acute myeloid leukemia had been randomized into busulfan/fludarabine and modified busulfan/cyclophosphamide groups. We retrospectively compared hematopoietic engraftment, regimen-related toxicity, graft-versus-host disease, transplant-related mortality, leukemia-free survival, and overall survival between the groups...

Animal models of kidney transplantation (KTX) are widely used in studying immune response of hosts to implanted grafts. Additionally, KTX can be used in generating kidney-specific knockout animal models by transplantation of kidneys from donors with global knockout of a gene to wild type recipients or vise verse. Dual kidney transplantation (DKT) provides a more physiological environment for recipients than single kidney transplantation (SKT). However, DKT in mice is rare due to technical challenges. In this study, we successfully performed DKT in mice and compared the hemodynamic response and graft function with SKT...

Background: Hematopoietic stem cell transplantation is considered the only curative therapy for very early-onset inflammatory bowel disease with specific immune defects, such as interleukin-10 receptor deficiency. We performed reduced-intensity conditioning before umbilical cord blood transplantation in patients with interleukin-10 receptor-A deficiency. Methods: We enrolled 9 very early-onset inflammatory bowel disease patients with typical manifestations. We diagnosed the patients with interleukin-10 receptor-A deficiency by whole-exome sequencing...

PURPOSE: Allogeneic haematopoietic stem-cell transplantation (HSCT) is a curative treatment for many haematologic cancers. Use of haploidentical (mismatched) donors increases HSCT availability but is limited by severe graft-versus-host disease (GvHD) and delayed immune reconstitution. Alloanergization of donor T-cells is a simple approach to rebuild immunity whilst limiting GvHD after haploidentical HSCT but the optimal T-cell dose and impact on immune reconstitution remain unknown.  Experimental Design: We performed a multicentre Phase 1 trial of alloanergized donor lymphocyte infusion (aDLI) after CD34-selected myeloablative haploidentical HSCT...

This study examined the impact of prednisone (PDN) on CMV infection after allogeneic stem cell transplantation (allo-SCT) according to donor (D) and recipient (R) CMV serostatus. Seventy-five patients underwent allo-SCT from June 2010 to July 2012. The risk of CMV infection according to D and R serostatus was defined as follows: high risk (HR) (D-/R+), intermediate risk (IR) (D+/R+ and D+/R-) and low risk (LR) (D-/R-). Forty-five patients (60%) developed CMV infection and forty-six patients (61%) received steroids (PDN ≥ 1 mg/kg/day) to treat acute Graft versus host disease (GvHD)...

Regulatory T cells (Tregs) are essential for the maintenance of tolerance and immune homeostasis. In allogeneic hematopoietic stem cell transplantation (aHSCT), transfer of appropriate Treg numbers is a promising therapy for the prevention of graft-versus-host disease (GVHD). We have recently reported a novel approach which induces the marked expansion and selective activation of Tregs in vivo by targeting TNF receptor superfamily 25 (TNFRSF25) and CD25. A potential advance to promote clinical application of Treg cells to ameliorate GVHD and other disorders would be the generation of more potent Treg populations...

Adult T-cell leukemia/lymphoma (ATL) is a peripheral T-cell lymphoma caused by the human T-cell lymphotropic virus type I. Patients with aggressive ATL show dismal prognoses, even with intensive dose-dense chemotherapy. Such patients often show chemo-refractoriness. Mogamulizumab (Moga) is a potent treatment option for patients with relapsed or refractory ATL. However, use of Moga before allo-HSCT could theoretically increase the risk of post-transplant complications like graft-versus-host disease (GVHD) as Moga depletes regulatory T-cells (Tregs)...

Improvement in chronic graft vs. host disease (cGvHD) following treatment with extracorporeal photopheresis (ECP) has been shown previously. However, the effect is often measured at only one point in time or as best response. Chronic GvHD activity fluctuates over time, so we retrospectively evaluated cGvHD responses in 54 patients with primarily moderate or severe cGvHD throughout the ECP treatment course and after stopping ECP. The dominant response was partial remission (PR) in 33 patients, no change (NC) in 10 patients, progressive disease (PD) in 10 patients and complete remission (CR) in one patient...

Acute graft-versus-host disease (GVHD) after liver transplantation (LTx) is a rare complication with a high mortality rate. Recently, monoclonal antibody (mAb) treatment, specifically with anti-interleukin-2 receptor antibody (IL2RAb) and anti-TNF-α antibody (TNFAb) gained increasing interest. However, evidence is mostly limited to case reports and the efficacy remains unclear. Here, we describe 5 patients with LTx-associated GVHD from our own center, and performed a systematic literature review to evaluate the potential therapeutic benefit of IL2RAb/TNFAb treatment...

Hematopoietic stem cell transplantation (HSCT) remains the only curative treatment in patients with β-thalassemia major. A matched sibling or a related donor is usually found in only 25%-30% of the patients. There are limited data on matched unrelated donor (MUD) transplants from India. We reviewed HSCT outcome in 56 children with TM who underwent 57 transplants at our center. Related donor (RD) (n=43) and MUD (n=14) transplants were performed with TreoFluT-based conditioning regimen in majority (95%) of patients...

Hematopoietic cell transplantation (HCT) is a common treatment for many disorders. Albuminuria post-HCT, which may represent endothelial injury or inflammation from graft vs. host disease, increases the risk of chronic kidney disease and non-relapse mortality at 1 year. HCT patients also have abnormal blood pressure (BP) and increased rates of cardiovascular complications. We sought to determine the relationships between albuminuria, endothelial dysfunction and BP in HCT patients. Patients ≥ 12 years of age who had their first allogeneic HCT between 2012-2015 and survived through day 80 were eligible...

BACKGROUND: The oral cavity is a common site of complications related to the cytotoxic effect of high-dose chemotherapy and radiation therapy. Considering our limited understanding of the burden of illness in the oral cavity from various cytotoxic therapies, it is difficult to produce evidence-based, preventive and management protocols. A prospective multicenter study is necessary to collect data on the burden of illness from various cytotoxic regimens. OBJECTIVE: The objectives of this prospective international observational multicenter study in hematopoietic stem cell transplant (HSCT) patients are to establish the nature, incidence and temporal relationship of oral complications related to conditioning regimens (chemotherapy with or without total body irradiation), stem cell transplantation and the immunologic reactions (mainly graft-vs-host-disease) that may follow, and to determine what subjective and objective oral complications related to treatment can predict negative clinical and economic outcomes and reduced quality of life...

Acute myeloid leukemia with inv(3)(q21;q26.2)/t(3;3)(q21;q26.2) (3q26 AML) is a rare disease with poor prognosis and median survival of <1 year. To evaluate allogeneic stem cell transplantation (alloHSCT) in the treatment of 3q26 AML, we studied 98 patients reported to the European Society for Blood and Marrow Transplantation between 1995 and 2013. Majority of patients were transplanted using peripheral blood, from unrelated donors and after myeloablative conditioning. Fifty-three patients were transplanted with active disease and 45 in complete remission...

BACKGROUND: Health state (HS) utility values for patients with acute myeloid leukemia (AML), a hematological malignancy, are not available in the United Kingdom (UK). This study aims to develop clinically sound HSs for previously untreated patients with AML and to assign utility values based on preferences of the general UK population. METHODS: This study was conducted in the UK and comprised 2 stages. During the first stage, AML HSs were drafted based on evidence from a literature review of AML clinical and health-related quality-of-life studies (published January 2000-June 2016) and patient-reported outcome measures previously used in this population...

BACKGROUND: Acute myeloid leukemia (AML) is both more common and with more biologically aggressive phenotype in the elderly. Allogenic stem cell transplantation (allo-SCT) is the best treatment option in fit patients. Either HLA-matched unrelated donor (MUD) or haploidentical (Haplo) donor are possible alternative for patients in need. METHODS: We retrospectively compared non-T-cell-depleted Haplo (n = 250) to 10/10 MUD (n = 2589) in AML patients ≥ 60 years...
