Filter by:The aim of this study is to assess the safety and feasibility of a short period of cold storage prior to normothermic machine perfusion in adult liver transplantation.
The aim of this study is to compare prospectively the ability of MRE and Transient Elastography in detection and staging of allograft fibrosis in comparison to Liver biopsy in patients who underwent Living Donor Liver Transplantation for complications related to HCV.
A randomized prospective study will be conducted of patients at Vanderbilt University Medical Center who undergo liver transplantation from March 2014 until approximately 120 patients are randomized. Patients will be randomized to undergo biliary reconstruction with and without stent placement.
This will be a prospective, multi-centre, biomarker trial comparing the accuracy of a new test (LiverMultiScan) against an existing test (liver biopsy) in the assessment of liver transplant recipients, designed in accordance with the STARD criteria. Study participants are 200 patients with liver transplant, due to undergo liver biopsy as part of serial evaluation of their liver health and to rule out rejection. The whole study will take 3 years with 2 years of recruitment The main aim is to investigate whether the introduction of LiverMultiScan as a standardised diagnostic test for liver disease can match the diagnostic yield of existing biopsies.
Glycemic control during liver transplantation is challenging especially after reperfusion of the liver graft. Insulin dose to treat postreperfusion hyperglycemia is retrospectively analyzed using historical data. The proposed dose then is prospectively applied to the patients to assess the adequacy of the insulin dose.
The aim of this research is to design a randomized controlled clinical study, which is based on HLA matching rate to guide tacrolimus regimen. In this study, the possibility of tacrolimus regimen guided by HLA matching rate will be explored, the occurrence rate of GVHD and rejection reaction will be observed, and the occurrence time and degree of adverse reactions caused by immune inhibitors will be identified. In the meantime, providing a possible prospect for prevention of GVHD and reduction or removal of immune inhibitors.
To study the influence of donor's ABCB1、CYP3A4、CYP3A5、POR genetic polymorphism on tacrolimus blood concentration in liver transplant recipients.
The study aimed to present our experience in treating recurrent HCV genotype 4 infection post living donor liver transplantation (LDLT) since introduction of the second generation direct acting antiviral drugs (DAAs) in Egypt.
The purpose of this study is to test the effects of hypothermic oxygenated machine perfusion (HOPE) in a phase-II prospective multicenter randomized clinical trial (RCT) on extended criteria donor allografts (ECD) in donation after brain death (DBD) orthotropic liver-transplantation (OLT) (HOPE-ECD-DBD). Human whole organ liver grafts will be submitted to 1-2 hours of HOPE via the portal vein directly before implantation and going to be compared to a control-group of patients transplanted after conventional cold storage (CCS). Primary (early graft injury) and secondary (e.g. postoperative complications, hospital stay, survival) objectives are going to be analysed in a 12 month follow up. Ischemia-reperfusion (I/R) injury and inflammation will be assessed using liver tissue, serum and bile samples as well as machine perfusion perfusate. To improve the availability of donor allografts and reduce waiting list mortality, graft acceptance criteria were extended increasingly over the decades. The use of extended criteria donor (ECD) allografts is associated with higher incidences of primary graft non-function (PNF) and/or delayed graft function (DGF). As such, several strategies have been developed aiming at "reconditioning" poor quality ECD grafts. HOPE has been tested intensively in pre-clinical animal experiments. Although, its known that HOPE can exert its reconditioning effect via cellular and mitochondrial pathways in the endothelial and parenchymal cells, there is still scarce evidence available on the exact subcellular mechanism of HOPE induced organ protection in the clinical scenario of liver transplantation. In donation after cardiac death (DCD) OLT, the positive effects of HOPE have been shown to reduce the incidence of biliary complications, mitochondrial damage and improve the overall cellular energy-status. In the HOPE setting, organ perfusion is performed in the transplant center shortly before the actual implantation with oxygenated perfusate using an extra corporal organ perfusion system. The first clinical study with this promising technique was recently reported in a Swiss cohort of patients who received DCD allografts. In organ donation after brain death (DBD), the only legally accepted approach for organ donation in most countries, HOPE and its effect on early graft injury and postoperative complications remains to be elucidated.
Study will be conducted on 20 patients ASA III-IV undergoing orthotopic liver transplantation. Blood samples will be obtained simultaneously from arterial line, pulmonary artery catheter and central venous catheter at 4 specific time points baseline, immediately after insertion of PAC; at the end of the dissection phase; 30 minutes after anhepatic phase; 30 minutes after unclamping. Blood samples will be also obtained whenever PPV is more than 15% and patient will need fluid therapy
