Severe graft-versus-host-disease is a major barrier for non T-cell-depleted haploidentical stem cell transplantation and there is no consensus on the optimal GVHD prophylaxis. This study compared the two most commonly used graft-versus-host-disease prophylaxis regimens (post-transplant-cyclophosphamide-based (PTCY) versus the anti-thymocyte-globulin-based (ATG)) in adults with acute myeloid leukemia reported to the european society for blood and bone marrow transplantation. 308 patients were analyzed, 193 received PTCY and 115 ATG as anti- graft-versus-host-disease prophylaxis...

Hyperacute rejection (HAR) is a rare event that can be prevented by crossmatch tests that detect anti-human leukocyte antigen antibodies against the donor. We present the case of a 43-year-old man who underwent a deceased-donor kidney transplantation with a negative complement-dependent cytotoxicity and a negative flow cytometry crossmatch. Luminex technology detected anti-DQ donor-specific antibodies (DSA) with a mean fluorescence intensity of 11,000. A single plasmapheresis session was carried out, followed by immunosuppression with immunoglobulin, antithymocyte globulin, tacrolimus, and methylprednisolone...

Objective: To assess the clinical feature and outcomes of severe aplastic anemia (SAA) patients suffered from bacteremia following antithymocyte globulin (ATG). Methods: A total of 264 cases hospitalized in our hospital between Jan 2000 and July 2011 were enrolled into this study. We evaluated the associated pathogens of bacteremia, analyzed the risk factors by Logistic regression and estimated the overall survival (OS) by Kaplan-Meier method for the cohort of patients. Results: Bloodstream infections occurred in 49 patients, with a median age of 20 (4-62) years, including 38 cases with very SAA (VSAA) and 11 SAA patients...

Aplastic anemia (AA) is a potential life-threatening hematopoietic stem cell (HSC) disorder resulting in cytopenia. The mainstays of treatment for AA are definitive therapy to restore HSCs and supportive measures to ameliorate cytopenia-related complications. The standard definitive therapy is HSC transplantation for young and medically fit patients with suitable donors and immunosuppressive therapy (IST) with antithymocyte globulin and cyclosporine for the remaining patients. A significant proportion of patients are refractory to IST or relapse after IST...

Graft-versus-host disease-free, relapse-free survival, which is defined as the absence of grade III-IV acute graft-versus-host disease, systemically treated chronic graft-versus-host disease, relapse, and death, is a novel, meaningful composite endpoint for clinical trials. To characterize risk factors and differences in graft-versus-host disease-free, relapse-free survival according to a variety of graft sources, we analyzed 23,302 patients with hematological malignancy who had a first allogeneic transplantation from 2000 through 2013 using the Japanese national transplant registry database...

BACKGROUND: The expression of proinflammatory cytokines in donor hearts after antithymocyte globulin (ATG) treatment given prior to organ removal was evaluated to analyze changes in inflammatory response. METHODS: Adult female OF-1 mice were randomized into brain death (BD) groups (BD Control, BD ATG) with or without treatment, and Controls (Control, ATG). BD induction was performed through gradual inflation of an intracranial positioned balloon-catheter. At the end of a 6-h observation period, ATG (1 mg/kgBW) was given intravenously...

BACKGROUND: Rabbit antithymocyte globulin (rATG) therapy has been shown to be beneficial in lung transplant recipients as induction therapy for treating acute lung rejection; however, its role in chronic lung rejection has been reported only rarely. We evaluated the effectiveness of rATG therapy in slowing the progression of chronic lung allograft dysfunction (CLAD) syndrome. METHODS: We conducted a retrospective review of 25 lung transplant patients with CLAD who received rATG therapy in the Pulmonary Institute of Rabin Medical Center, Israel, between May 2005 and February 2016...

Epstein-Barr virus-associated lymphoproliferative disorder (EBV-LPD) is a currently emerging serious complication in immunosuppressed patients, especially in allogeneic transplant recipients. Several fatal cases of EBV-LPD have been reported in aplastic anemia (AA) patients receiving immunosuppressive therapy (IST) with antithymocyte globulin (ATG) plus cyclosporine A (CsA), but no appropriate prophylactic or therapeutic strategy has been established. Herein, we describe a 29-year-old man whose EBV-LPD was successfully treated with rituximab...

INTRODUCTION: Aplastic Anaemia (AA) is a syndrome characterized by peripheral pancytopenia with hypo-cellular marrow. Acquired idiopathic AA is the most common variety, probably of an autoimmune aetiology. Bone Marrow Transplantation (BMT) is the treatment of choice but cost is the limiting factor. Antithymocyte Globulin and Cyclosporine-A is an alternative to BMT. Cyclosporine alone has been tried as a single agent in resource poor setting. AIM: The study was conducted with the aim to observe the treatment response in aplastic anaemia to Cycloserine-A...

There is currently no consensus regarding the dose or duration of rabbit antithymocyte globulin (rATG) induction in different types of heart transplant patients, or the timing and intensity of initial calcineurin inhibitor (CNI) therapy in rATG-treated individuals. Based on limited data and personal experience, the authors propose an approach to rATG dosing and initial CNI administration. Usually rATG is initiated immediately after exclusion of primary graft failure, although intraoperative initiation may be appropriate in specific cases...

BACKGROUND: De novo use of mammalian target of rapamycin inhibitors after kidney transplantation is associated with a concentration-dependent incidence of wound healing adverse events (WHAE). The objective of this analysis was to compare the incidence of WHAE in patients receiving everolimus (EVR) or mycophenolate sodium (MPS). METHODS: This was a predefined sub-analysis of a single center prospective randomized study in which 288 kidney transplant recipients receiving tacrolimus (TAC) and prednisone were randomized for 3 different regimens: antithymocyte globulin (r-ATG)/EVR (N=85); basiliximab (BAS)/EVR (N=102); BAS/MPS (N=101)...

BACKGROUND: Rejection remains the leading cause of allograft loss, and a major barrier to improving long-term outcomes following intestinal transplantation (ITx). Our aim is to define the prevalence and investigate the role of donor-specific antibody (DSA) on intestinal graft outcomes. METHODS: The study includes 109 transplants performed in 95 recipients at a single center. Patients were screened for DSA pretransplant, monitored regularly posttransplant and when clinically-indicated using the single-antigen bead Luminex assay...

A total of 21 patients with severe aplastic anemia (SAA) underwent marrow transplantation from HLA-identical siblings following a standard conditioning regimen with cyclophosphamide (50 mg/kg/day × 4 days) and horse antithymocyte globulin (30 mg/kg/day × 3 days). Post-grafting immunosuppression consisted of a short course of methotrexate (MTX) combined with cyclosporine (CSP). The transplant protocol tested the hypothesis that the incidence of chronic GvHD could be reduced by limiting the marrow grafts to ⩽2...
