Filter by:It has been identified that nonadherence to immunosuppressant regimen may cause long-term graft failure and death in solid organ transplant recipients. Therefore, simplification of the immunosuppression regimen by reducing daily dosing frequency may improve long-term outcome. The investigators will examine pharmacokinetics and safety profiles of stable liver transplant recipients receiving twice-daily TAC with EVR (BID) regimen and then being converted to once-daily TAC with EVR (QD) regimen over a 6-month study period post-conversion.
the aim in this study to assess the effect of fluid management in patient undergoing orthotopic liver transplantation either by using pulse pressure variation or by central venous pressure. we will assess the impact of fluid management by either methods on oxygenation and extra vascular lung water visualized by lung ultrasound.
Single centre, open-label, randomized, controlled, cross over study to evaluate the pharmacokinetic and bioavailability of Envarsus® in comparison to Advagraf® in de novo liver transplant recipients
The study is a prospective observational mono center study Primary objective : Study the anti-HLA antibodies frequency preformed before liver transplantation and the kinetic of appearance of DSA and de novo complement-binding anti-HLA antibodies after liver transplantation. Secondary objective : - Risk factor of de novo DSA appearance (Immunosuppressive therapy, liver aetiology) - Impact of DSA on: - Graft and patients survivals - Onset of allograft rejection (acute, late-onset, chronic) - Unexplained liver graft dysfunction - Unexplained liver enzymes abnormalities - Liver fibrosis development (liver stiffness study using fibroscan©)
Interest in vitamin D has seen an unprecedented revival sparked by the finding that vitamin D has pleiotropic effects with an intriguing link to the critically ill patients. The recent VITdAL-ICU RCT found a significant difference in mortality in patients with severe deficiency when high doses of vitamin D supplementation were administered. Vitamin D deficiency is extremely common in patients with chronic liver disease and/or cirrhosis. It seems to be a marker of severity of the disease, but also a possible contributing factor in determining poor outcomes. Design of the study: Observational prospective study. Primary variable end point: Vitamin D at baseline, and POD (post-operative day) 1, 3, 7, 28. Secondary variable end points: ICU length of stay; SAPS 2 and SOFA score at POD 1, 7; Days of mechanical ventilation; Hospital length of stay; Mortality at POD 28; Diagnosed invasive infections; Graft rejection in the first 28 days; Bilirubin and INR at POD 7 and 28. SAFETY. The patient will not undergo to additional procedure during the study and will be asked for consent to treatment of personal data. SAMPLE SIZE. Because of the lack of knowledge in this specific cohort no formal sample was calculated beforehand. The sample size will be defined by one-year clinical activity: about 60 consecutive patients. STATISTICAL ANALYSIS. All statistical analysis and results will be assessed and reported as exploratory analysis. In order to describe the trend over time of the vitamin D levels, descriptive statistics such as mean, median, interquartile range and standard deviation will be evaluated. In addition, 95% confidence intervals for mean and standard deviation will be reported. Comparisons between two temporal observations will be assessed with paired t-test. Any univariate association between factors or covariates, will be explored. Statistical analyses will be done with SAS 9.4,
aim of our study to validate electrical cardiometry readings against same readings by transoesophageal echo. we will validate stroke volume (SV) readings stroke volume variation(SVV), index of contractility.
This study aims to evaluate if the risk of developing ventral hernia after liver transplantation can be reduced through the prophylactic implantation of a synthetic, fully resorbable mesh "Phasix" in the course of liver transplantation. Patients will be randomized in a 1:1 ratio to receive either Phasix mesh or standard surgery without the use of Phasix. Ultra-sound examinations of the wound area will be performed 14 days, 3, 6 and 12 months after liver transplantation. Furthermore, presence of infections, seroma, pain and other problems in the wound area will be assessed.
Project LIFT is a randomized, controlled trial that tests the effectiveness of a remotely-monitored, home-based exercise program utilizing wearable fitness trackers to monitor steps taken per day, health engagement questions, and financial incentives. 120 subjects will be randomized into 3 arms: 1) usual care - no fitness tracker or incentive, 2) a fitness tracker + no incentives, and 3) fitness tracker plus financial incentives.
A study of patient adherence and convenience to immunosuppressive agents in newly liver transplant recipients - a prospective, multi-center, open-labeled, randomized clinical trial for comparison between once-daily early conversion and twice-daily tacrolimus formulation.
A prospective, multi-center, non-randomized, observational, consecutive case series, which will compare Endoscopic Retrograde Cholangiopancreatoscopy (ERCP) and cholangioscopy with Spy Glass Digital System (DS) procedure at 5-10 centers.
