Filter by:The objectives of the study are to determine the impact of interferon-free treatment for the hepatitis C virus (HCV) on peripheral blood immune cell phenotype and soluble immune-related proteins in blood, while controlling for genetic polymorphisms known to impact HCV-related immune responses, and to determine the impact of the therapy on the emergence of drug-resistant HCV. The study design is informed by the researchers recent investigations of patients receiving HCV treatment. About 4% of patients who had not undergone liver transplantation experienced hepatic decompensating or another serious event. There were several cases of bacterial infection and two cases with elevated markers of autoimmune processes. These events suggest that treatment altered immune responses. About 25% of patients who had undergone liver transplantation experienced hepatic decompensating or another serious adverse event. The long term goal is to understand the pathophysiology of these complications and determine whether HCV treatment can cause an immune reconstitution syndrome in susceptible patients, while improving antimicrobial defenses in others
This study will be to prospectively determine differences in Surgical Site Infection (SSI) if a prolonged course of post-operative antibiotics are used following liver transplantation.
Cirrhotic patients undergoing liver transplantation are at very high risk of post operative complication such as post-operative residual curarization. Rocuronium is a neuromuscular blocking agent that nowadays can be safely and rapidly antagonized with sugammadex. No one study compared sugammadex versus neostigmine after rocuronium infusion during liver transplantation.
Acute or chronic liver failure (fulminant hepatitis or advanced cirrhosis) disrupts brain physiology. Beyond classical hepatic encephalopathy, intracranial hypertension may occur.During liver transplantation (LT) surgery, many factors can lead to cerebral assault. In addition, intracranial hypertension measured with invasive methods has been described in certain phases of LT, especially at the time of reperfusion. The invasive monitoring of the intracranial pressure is not used in these patients, due to a high risk of infection and bleeding. The non-invasive monitoring of intracranial pressure has been widely developed in recent years : transcranial doppler and recently ultrasound of the optic nerve sheath (ONSD) allow an effective detection of intracranial hypertension.
The aim of this study is to validate in the context of liver transplantation, the interest of the cccDNA assay technique developed by the team of Professor Zoulim (INSERM U1052) on liver biopsy and correlate this assay cccDNA in hepatitis B virus (HBV) viral load and serum liver through several groups of patients at transplantation (on graft and native liver explant) and after transplantation.
The purpose of this study is to describe SpyGlass choledochoscopy in patients with post orthotopic liver transplant (OLT) biliary strictures prior to endoscopic therapy and ductal changes after treatment stents.
The primary aim of this study is to determine whether a peripheral blood or graft lymphocyte phenotype of immune senescence or exhaustion is different between operationally tolerant and non-tolerant liver allograft recipients.
A prospective, phased-pivotal, international randomized trial to evaluate the effectiveness of the OCS™ Liver to preserve and assess donor livers intended for transplantation.
Normothermic machine perfusion (NMP) preservation is a promising method to decrease the complication of marginal donor livers compared to cold storage (CS). The aim of this project is to assess safety and feasibility of NMP in human liver transplantation. This will be a single center prospective cohort pilot study. Thirty-two livers with acceptable quality for transplantation will be preserved with NMP in 2-18 hours and transplanted. The follow-up period will be 6 months post-transplantation. The outcome will be compared to 100 historical patients transplanted in our program in the past 5 years (liver preserved using CS) with matched characteristics on age, Model for End-Stage Liver Disease (MELD) score, preservation time, etc.
Some of the liver transplantation recipients experience postoperative acute kidney injury due to various causes including genetic factors. Prevention of postoperative acute kidney injury is essential for postoperative care in liver transplantation recipients. The aim of this study is to investigate the relationship between gene polymorphisms which have been known to be associated with postoperative acute kidney injury, and the occurrence of acute kidney injury after liver transplantation.
