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...

BACKGROUND The diagnosis of post-liver transplant biliary strictures (BS) requires a high degree of clinical suspicion because of the diversity of symptoms and usually mild clinical presentation. If quickly treated, successful outcome is achieved most cases. The aim of our study was to analyze the value of diagnostic methods in BS after pediatric LTx. MATERIAL AND METHODS We retrospectively reviewed clinical data of children with BS after liver transplantation, with the main focus on diagnostic methods, including imaging studies and histology...

BACKGROUND: Graft-derived cell-free DNA (GcfDNA), which is released into the blood stream by necrotic and apoptotic cells, is a promising noninvasive organ integrity biomarker. In liver transplantation (LTx), neither conventional liver function tests (LTFs) nor immunosuppressive drug monitoring are very effective for rejection monitoring. We therefore hypothesized that the quantitative measurement of donor-derived cell-free DNA (cfDNA) would have independent value for the assessment of graft integrity, including damage from acute rejection...

In most countries, patients with lungs destroyed by tuberculosis (TB) are excluded from lung transplantation (LTx) because of concerns about TB recurrence. LTx may be an effective therapeutic option for patients with chronic respiratory failure, but there are no reports of successful LTx in patients with lungs destroyed by TB. We present the case of successful single LTx in a patient with chronic respiratory failure after pneumonectomy with antituberculous chemotherapy. At the 16-month follow-up, he did not show any evidence of TB recurrence and his respiratory problems and quality of life were improved by LTx...

INTRODUCTION: Little data exists regarding optimal therapeutic strategies post-operatively after lung transplant (LTx). Current practice patterns rely on expert opinion and institutional experience resulting in non-uniform post-operative care. To better define current practice patterns, an international survey of LTx clinicians was conducted. METHODS: A 30-question survey was sent to transplant clinicians via email to the ISHLT open forum mailing list and directly to the chief transplant surgeon and pulmonologist of all LTx centers in the United States...

BACKGROUND: Neurological disorders due to calcineurin inhibitor (CNI) treatment pose a well-known problem after liver transplantation (LTx). In this study, the impact of CNIs on cognitive functioning during maintenance therapy was analyzed. A possible improvement of cognitive functioning, compliance and health-related quality of life (HRQoL) after conversion to a once-daily tacrolimus formulation was prospectively assessed. METHODS: In a cross-section analysis cognitive functioning of living donors (LD), waiting list patients and LTx patients was tested using a 4 times trail making test (4-TTMT)...

Low muscle mass is common in lung transplant (LTx) candidates, however, the clinical implications have not been well described. The study aims were to compare skeletal muscle mass in LTx candidates with controls using thoracic muscle cross-sectional area (CSA) from computed tomography and assess the association with pre- and post-transplant clinical outcomes. This was a retrospective, single centre cohort study of 527 LTx candidates (median age: 55 IQR [42-62] years; 54% male). Thoracic muscle CSA was compared to an age-and sex-matched control group...

Post-transplant lymphoproliferative disorder (PTLD) may compromise long-term outcome of lung transplant (LTx) recipients. A case-control study was performed, comparing LTx recipients with PTLD (n=31) to matched recipients without PTLD (Controls, n=62). Risk factors for PTLD and post-transplant outcomes were assessed. PTLD prevalence was 3.9%, time to PTLD 323 (166-1132) days; and 54.8% had early-onset PTLD versus 45.2% late-onset PTLD. At LTx, more Epstein-Barr virus (EBV)-seronegative patients were present in PTLD (42%) compared to Controls (5%) (P<...

BACKGROUND: The allocation of donor lungs for transplantation in Germany was changed on 10 December 2011 to a system based on the Lung Allocation Score (LAS). The aim of the present study is to determine whether this change has prolonged the survival of patients on the transplant waiting list and of those who have undergone lung transplantation (LTx). METHODS: We retrospectively compared data from the three-year periods before and after the change to an LAS-based allocation system (2009-2011 vs...

Antibodies against HLA and non-HLA are associated with transplantation outcome. Recently, pretransplant serum IgG antibody levels against apoptotic cells were found to correlate with kidney allograft loss. We investigated the presence of these antibodies in lung transplantation (LTx) patients and evaluated the correlation of pre-LTx serum levels of IgG antibodies against apoptotic cells with LTx outcome. These cells included donor lung endothelial cells (ECs) obtained from lung perfusion fluid collected during LTx procedure...

BACKGROUND: Lung transplantation (LTx) is offered to older and more complex patients who may be at higher risk of skeletal muscle dysfunction, but the clinical implications of this remain uncertain. The study aims were to characterize deficits in skeletal muscle mass, strength and physical performance and examine the associations of these deficits with clinical outcomes. METHODS: Fifty LTx candidates (58% male, 59 ± 9 years) were prospectively evaluated for skeletal muscle deficits: muscle mass using bio-electrical impedance, quadriceps, respiratory muscle and handgrip strength, and physical performance with the Short Physical Performance Battery...
