Growing evidence suggests a relationship between antibody-mediated rejection (AMR) and early graft failure due to a previously unknown etiology in liver transplantation (LTx). We herein report a three-year-old boy who developed rapid graft failure due to de novo donor-specific antibody (DSA)-driven AMR a week after living donor LTx, requiring a second transplant on the 10th day after the first LTx. The pathology of the first graft showed massive necrosis in zone 3 along with positive C4d and inflammatory cell infiltrates in portal areas...

BACKGROUND: The average ages of lung transplant (LTx) recipients and donors are increasing. With older recipients considered to be especially at high risk of posttransplant mortality, we sought to determine whether the use of allografts from older donors affects survival among older patients undergoing LTx. METHODS: The United Network for Organ Sharing registry was used to identify patients aged 65-80 y receiving a first-time LTx between 1987 and 2013. Survival analysis examined implications of a donor-recipient age difference >10 y using Cox proportional hazards regression...

BACKGROUND: Activins A and B, members of the TGF-β superfamily, are produced as part of the physiological response to tissue damage and the resulting proinflammatory response. Given that lung allograft reperfusion results in an inflammatory response, it is likely that the activins and their binding protein follistatin will form part of the regulatory response. There is a need to document the response of these proteins to allograft reperfusion to determine if there is a role for the use of follistatin to control the biological actions of the activins because some of these are potentially damaging...

BACKGROUND: Pulmonary rehabilitation (PR) following lung transplantation (LTx) has been shown to be effective with regard to exercise capacity and health-related quality of life (HRQL). However, outcome data is limited with respect to LTx as a population. Differences concerning the effects of PR in patients with single LTx (SLTx) or double LTx (DLTx) have not been studied yet. OBJECTIVES: The aim was to compare possible differences concerning PR outcomes between SLTx and DLTx...

Despite its rarity (1%-2%), acute graft-versus-host disease after liver transplantation (LTx-aGVHD) has a high mortality rate (85%). A gradual decrease in regulatory T cells (T-regs) correlates with disease progression in a rat LTx-GVHD model and treatments which increase T-regs exert therapeutic effects on LTx-aGVHD. In this study, LTx-aGVHD model rats were treated with rapamycin (RAPA), OSI-027 or an equal quantity of vehicle. Rats treated with OSI-027 survived longer (>100 days) than those in the RAPA (70±8 days) or control (24±3 days) groups...

The enzymatic defect in MSUD results in accumulation of neurotoxic metabolites of BCAAs. LTX has shown to be a feasible strategy in patients non-responsive to diet. Because of sufficient enzyme activity in extrahepatic tissues in healthy people, the MSUD liver graft is a suitable domino organ. We present the first case of a technical challenging ex situ split of a MSUD domino organ transplanted into two pediatric recipients. The domino graft donor was a 21-year-old female (58 kg) suffering from MSUD with recurrent metabolic decompensation despite strict diet...

The frequency-modulated continuous-wave reflectometer on LTX (Lithium Tokamak Experiment) and the data analysis methods used for determining electron density profiles are described. The diagnostic uses a frequency range of 13.1-33.5 GHz, for covering a density range of 0.21-1.4×10(13) cm(-3) (in O-mode polarization) with a time resolution down to 8 μs. The design of the diagnostic incorporates the concept of an "optimized" source frequency sweep, which minimizes the large variation in the intermediate frequency signal due to a long dispersive transmission line...

Little has been studied regarding the diets of children following LTX. The study aim was to assess and compare dietary intake and DQ of healthy children and children post-LTX. Children and adolescents (2-18 years) post-LTX (n=27) and healthy children (n=28) were studied. Anthropometric and demographic data and two 24-hour recalls (one weekend; one weekday) were collected. Intake of added sugar, HFCS, fructose, GI, and GL was calculated. DQ was measured using three validated DQ indices: the HEI-C, the DGI-CA, and the DQI-I...

Cystic fibrosis (CF) is a common indication for lung transplantation (LTx) in children and adults with severe and irreversible lung disease. In the setting of LTx in the CF population, immunosuppressive medications are used to prevent allograft rejection despite the majority of these patients being chronically infected with numerous, and often antibiotic-resistant, pathogens. There is limited evidence for the optimal post-LTx immunosuppression regimen in patients with CF, particularly in children. This article provides a review of immunosuppression regimens in the pediatric and adult CF post-LTx population, investigating drug dosing and monitoring, and medication combinations...

BACKGROUND: Lung transplantation (LTx) is limited by the shortage of suitable donors. To overcome this problem, many programs have begun to use donors with extended criteria (marginal donors). However, brain-dead patients with implanted mechanical circulatory support system have rarely been considered as potential lung donors. This case demonstrates the feasibility of lung transplantations from organ donors supported by a mechanical circulatory support system despite the possible difficulties of lung retrieval...

Short hairpin RNA of frizzled-2 (shRNA-Fz2) suppresses the cell proliferation of gastric cancer cells. Endoscopic ultrasound (EUS) is considered a suitable method for the introduction of therapeutic plasmids into cells, since the device enables the access and real-time monitoring of gastric cancer tissues. In the present study, plasmids were introduced into cells by sonoporation, as evidenced by the production of H2O2. The production of H2O2 was measured by absorbance of a potassium-starch solution irradiated with EUS...

Diastolic dysfunction may influence perioperative outcome, early graft function and long-term survival. We compared the outcomes of DLTx for PAH patients with pre-operative LV diastolic dysfunction to those without diastolic dysfunction. Of 116 consecutive patients with PAH (who underwent transplantation between January 1995 and December 2013), 44 met our inclusion and exclusion criteria. Fourteen patients (31.8%) with diastolic dysfunction pre-LTx had a higher BMI [29 (IQR 21.5-32.6) vs. 22.4 (IRQ 19.9-25...

Gene reporter technology (GRT) has opened several new avenues for monitoring biological events including the activation of transcription factors, which are central to the study of nutrigenomics. However, this technology relies heavily on the insertion of foreign plasmid DNA into the nuclei of cells (i.e., transfection), which can be very challenging and highly variable among cell types. The objective of this study was to investigate the optimal conditions to generate reliable GRT assay data on bovine immortalized cell lines, Madin Darby Bovine Kidney (MDBK) and bovine mammary epithelial alveolar (MACT) cells...

The oncolytic peptide LTX-315, which has been de novo designed based on structure-activity relationship studies of host defense peptides, has the ability to kill human cancer cells and induce specific anticancer immune response when injected locally into tumors established in immunocompetent mice. The oncolytic effect of LTX-315 involves perturbation of plasma membrane and the mitochondria with subsequent release of danger-associated molecular pattern molecules, which highlights the ability of LTX-315 to induce complete regression and protective immune responses...

BACKGROUND: The impact of pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD) on survival after lung transplantation (LTx) is not known. MATERIAL AND METHODS: First-time adult LTx recipients with COPD transplanted between May 2005 and September 2013 were identified in the United Network for Organ Sharing Registry database, and tracked from transplant date until death or censoring. Right heart catheterization (RHC) measurements at time of wait listing were used to predict all-cause mortality after LTx, with multivariable analyses stratified by transplant type...

BACKGROUND: Insults to the airway epithelium play a key role in constrictive bronchiolitis following lung transplantation (LTx), the typical hallmark of chronic rejection. Our hypothesis is that immunosuppressives might affect airway integrity. METHODS: A biculture of lung bronchial epithelial cells (16HBE) and lung microvascular endothelial cells (HLMVEC) was exposed to immunosuppressives (serum through levels) for 24h or 4 days. Cytotoxicity, trans-epithelial electrical resistance (TEER) and permeability was measured after exposure to monotherapies and combination therapies...

Lung transplantation (LTx) is the last treatment for patients suffering from end-stage lung diseases. Survival post-LTx is hampered by the development of the bronchiolitis obliterans syndrome (BOS) and diagnosis is often late. Given the urgent clinical need to recognize BOS patients at an early stage, we analyzed circulating miRNAs to identify possible stratification markers for BOS development post-transplantation. Therefore, pro-fibrotic (miR-21, miR-155), anti-fibrotic (miR-29a) and fibrosis-unrelated (miR-103, miR-191) miRNAs were analyzed in serum of end-stage lung disease patients and during LTx follow-up...

An elevation in plasma cardiac troponins is an indicator of increased perioperative risk in orthopaedic and vascular surgery, however, data on liver transplantation (LTx) are scarce. The aim of the study was to evaluate the prevalence of cardiac troponin I (cTnI) elevation in the perioperative period of LTx, and its potential relationship with 1-year mortality. MATERIAL AND METHODS: Analysis included 79 patients with liver cirrhosis. During LTx all patients underwent hemodynamic measurements...
