BACKGROUND: Cytomegalovirus (CMV) has a role in chronic rejection and graft loss in kidney transplant (KTx) and lung transplant (LTx) recipients. In addition, donor CMV seropositivity is an independent risk factor for renal graft loss. The anti-CMV response might modulate this risk. Expression of programmed cell death 1 (PD-1), a receptor involved in viral-specific T-cell exhaustion, is influenced by a single nucleotide polymorphism called PD-1.3 (wild-type allele G, variant allele A)...

PURPOSE: Patients with cystic fibrosis (CF) often experience low bone mineral density (BMD) pre- and post-lung transplantation (LTX). The study purpose was to describe BMD and micronutrient status in adults with CF pre- and post-LTX. METHODS: Twelve patients with CF (29 ± 8 years) were recruited from the CF clinic at the University of Alberta Lung Transplant Program. BMD and vitamins A, D, E, K status, and parathyroid hormone were measured pre- and post-LTX. RESULTS: No significant differences pre- and post-LTX were observed at the different bone sites measured (lumber-spine, femoral-neck (FN), hip, and femoral-trochlea) (P > 0...

The single most important cause of late mortality after lung transplantation is chronic lung allograft dysfunction (CLAD). However, the pathological development of CLAD was not as simple as previously presumed and subclassification phenotypes, bronchiolitis obliterans syndrome (BOS) and restrictive CLAD (rCLAD), have been introduced. We want to re-investigate how CLAD manifests in the murine orthotopic lung transplant model and investigate the role of interleukin 17A (IL-17A) within this model. Orthotopic LTx was performed in CB57Bl6, IL-17 WT and IL-17 KO mice...

OBJECTIVE: Zonal organ allocation system comprises organ procurement by teams within a specific geographical area of each retrieval team. Therefore, in a substantial number of cases organs are retrieved by 'foreign' teams and are sent for transplantation to the implanting centre. The aim of this study was to assess the impact of zonal organ allocation system on early- and long-term outcomes after lung transplantation (LTx). METHODS: Included were 331 consecutive patients who underwent LTx performed at Harefield Hospital between January 2007 and January 2015...

BACKGROUND: Duration of index hospitalization after lung transplantation (LTx) is an important variable that has not received much attention. We sought to determine independent predictors of prolonged hospital length of stay (LOS) and its association with early and late outcomes. METHODS: The United Network of Organ Sharing database was queried for adult patients undergoing LTx between 2006 and 2014 (N = 14,320). Patients with dual organ or previous transplantation and patients who died during the first 25 days after LTx were excluded (n = 12,647, mean age 55...

BACKGROUND: In lung transplantation (LTx), patients with thoracic muscle sarcopenia may have to require longer to recovery. We measured thoracic muscle volume by using the cross sectional area (CSA) and assessed its effect on early outcomes after LTx. METHODS: A retrospective analysis was conducted to evaluate the effect of thoracic sarcopenia in patients undergoing LTx between January 2010 and July 2015. The lowest CSA quartile (Q1) was defined as sarcopenia. RESULTS: In total, 109 patients were enrolled...

Bronchiolitis obliterans syndrome (BOS) is a main cause of allograft dysfunction and mortality after lung transplantation (LTx). A better understanding of BOS pathogenesis is needed to overcome this treatment-refractory complication. Orthotopic tracheal transplantation using human bronchus was performed in Brown Norway (BN) and nude (RNU) rats. Allografts were recovered in both strains at Day 7 (BN7 , n = 6; RNU7 , n = 7) or Day 28 (BN28 , n = 6; RNU28 , n = 6). Immune response of the host against the bronchial graft was assessed...

Objective To explore the influence of the exogenous Jaagsiekte sheep retrovious (exJSRV) envelope protein (Env) on NIH3T3 cell proliferation. Methods A recombinant plasmid pcDNA4/myc-His/exJSRV- env carrying exJSRV- env gene was constructed, and then the correctness of the recombinant plasmid was identified by PCR, restriction enzyme digestion and sequencing. The recombinant plasmid pcDNA4/myc-His/exJSRV- env was transiently transfected into NIH3T3 cells by Lipofectamine(TM) LTX. After the transfection of the recombinant plasmid, the expression of exJSRV- env was detected by reverse transcription PCR and Western blotting...

Acute AMR is well reported following ABO-incompatible LTx. However, it remains uncommon in ABO-compatible LTx. It typically presents with graft dysfunction ≤2 weeks post-LTx and is often associated with graft loss. We report the clinical presentation, treatment regimen, and outcome of six pediatric LTx recipients diagnosed with early acute AMR based on (i) clinical signs of graft dysfunction, (ii) histopathology indicative of acute injury ± C4d staining, and (iii) presence of HLA DSA. All patients developed elevated ALT and GGT ≤ 45 days post-LTx...

Background Pre-lung transplant (LTx) panel reactive antibody (PRA) levels are associated with adverse outcomes in adult LTx recipients, but their impact in pediatric LTx recipients is unknown. Methods The United Network for Organ Sharing registry was queried from 2004 to 2013 to compare survival between pediatric LTx recipients with PRA class I and II levels = 0 versus > 0. Results Overall, 333 pediatric LTx recipients had data on class I or II PRA and were included in the analysis. Univariate analysis demonstrated that PRA > 0 was not associated with survival benefit for class I (hazard ratio [HR] = 0...

LTX-401 is an oncolytic amino acid derivative with potential immunogenic properties. Here, we demonstrate that LTX-401 selectively destroys the structure of the Golgi apparatus, as determined by means of ultrastructural analyses and fluorescence microscopic observation of cells expressing Golgi-targeted GFP reporters. Subcellular fractionation followed by mass spectrometric detection revealed that LTX-401 selectively enriched in the Golgi rather than in mitochondria or in the cytosol. The Golgi-dissociating agent Brefeldin A (BFA) reduced cell killing by LTX-401 as it partially inhibited LTX-401-induced mitochondrial release of cytochrome c and the activation of BAX...

BACKGROUND: Recently, antibody mediated rejection (AMR) has been associated with a higher incidence of chronic lung allograft dysfunction (CLAD) and mortality after lung transplantation (LTx). We investigated markers related to AMR and matrix remodeling in CLAD, with special attention for its two phenotypes being bronchiolitis obliterans syndrome (BOS) and restrictive CLAD (rCLAD). METHODS: Immunoglobulins (IgA, IgE, IgG1-IgG4, total IgG and IgM) and complement (C4d and C1q) were quantified in lung lavage samples at the moment of BOS (n=15) or RAS (n=16) diagnosis; and were compared to stable transplant patients who served as control (n=14)...

Excellent survival rates in paediatric LTx have resulted in increasing numbers of young people transferring from paediatric to adult care. Understanding the mechanisms of successful transition is imperative for ensuring good long-term outcomes and developing services for young people. Semi-structured interviews were conducted with 17 young people (10 females; age range: 15.2-25.1 years). Eight were within 1 year of transferring to adult services; nine had transferred. Interviews were analysed using IPA. Analysis revealed two major themes in both pre- and post-transfer groups: "relationships with healthcare professionals" and "continuity of care...

The frequency of non-alcoholic fatty liver disease (NAFLD) has continously increased over the last few decades in parallel with the increasing prevalence of metabolic syndrome. With the increasing frequency of obesity and type 2 diabetes an increase in non-alcoholic steatohepatitis (NASH) is also to be expected. The NASH-associated liver cirrhosis and primary hepatocellular carcinoma (HCC) are indications for liver transplantation (LTX), which is gaining importance in Germany. In contrast, liver cirrhosis as a result of alcoholic steatohepatitis (ASH) is already the leading cause for LTX in Germany...
