Filter by:Many studies describe the relationship between microbiota alteration and the occurrence of metabolic, alcoholic or inflammatory liver diseases. Nevertheless, the modifications of microbiota during liver transplantation (LT) as well as its implication are poorly studied. Similarly, only the intestinal microbiota is studied in this context, and no data are available on the biliary microbiota, even if it is known that bile microbiota can interfere with hepatobiliary diseases. This study proposes a clinical and biological in-depth follow-up with multiple sampling of liver transplanted patients to study biliary and intestinal microbiota alterations along LT, as well as bile acids metabolism in corresponding fluids. Indeed, in recipient samples as saliva, blood, urine, and feces can be taken before LT, and surgeons can easily perform bile sampling during LT. In donors all samples can be taken during liver removal. This offers the opportunity to have a microbiotic landscape of individuals without liver disease (donor), and patients suffering from a chronic liver disease or a liver cancer before and after transplantation. Also, in Grenoble University hospital, in case of biliary anastomotic incongruence, a biliary stent is placed during LT in 60% of recipients. This stent is removed by endoscopic retrograde cholangiopancreatography (ERCP) within 6 months after LT, offering a second opportunity to obtain bile samples in transplanted patients, after the early post-LT period. Patients who do not require a biliary stent will also be included for the study of secondary objectives, as intestinal microbiota is very poorly characterized in liver transplanted patients too. A portion of the patients without biliary stent, may also develop an anastomotic biliary stricture requiring an ERCP. If this ERCP is realized within the follow-up period of the study, the patient will also be included in the primary objective of the study. These multiple and sequential samples will allow a complete analysis of microbiota changes in LT patients and aim to answer to 3 questions: 1. What are the modifications of intestinal and biliary microbiomes during LT? 2. What is the influence of bile acids' composition on intestinal and biliary microbiota? 3. What are the relationships between microbiome alterations and the emergence of LT complications?
The hypothesis is that the Alfapump® strategy would be more effective in terms of QALYs generated , and that the cost of Alfapump® device and its implantation will be totally or partially offset by the reduction in the number of evacuating parentheses performed and the reduction in the number of complications in patients with refractory ascites awaiting liver transplantation or not. On the other hand, given the difference in the clinical profiles of these two populations (whether or not they are awaiting transplantation), these two populations will be study separately Evaluation of the medical-economic impact at 1 year of the two therapeutic strategies: implantation of Alfapump® versus repeated evacuating paracentesis in cirrhotic patients with refractory ascites without scheduled liver transplantation.
The purpose of this study is to determine the feasibility of a home meal delivery program for patients with cirrhosis and ascites and to determine the effectiveness of a salt-restricted (2 gram sodium) meal delivery program in reducing the need for therapeutic paracenteses and/or all-cause re-admissions for these patients. Many patients with cirrhosis don't have enough nutrients in the body and are frail and these meals may help them maintain a good diet and lead to improved quality of life.
Heptorenal syndrome (HRS) is divided into two types. A non-acute kidney injury (NAKI-HRS), which is predominantly related to end-stage disease and a more acute kidney injury (HRS-AKI). HRS-AKI is potentially reversible and develops subsequent to aggravation of a systemic circulatory vasodilatation, that triggers renal vasoconstriction and deteriorates renal perfusion and function. The albumin and terlipressin response is evaluated clinically, routinely for a week and reduces mortality with 23% compared to no treatment. Only 40-50% of the patients with HRS-AKI respond to the treatment with terlipressin. The treatment of hepatorenal syndrome (HRS-AKI) is aimed at improving blood flow to the kidneys. Flow changes associated to development of HRS have only sparsely been studied and not previously by MR technique and no previous studies have evaluated changes in flow induced by terlipressin. It has been hypothesized that development of HRS is associated to a deterioration in heart function with development of cardiomyopathy, which together with renal vasoconstriction leads to renal failure. Simultaneous MR-assessments of cardiac function and flows (especially the renal flow) in HRS-AKI have not previously been performed. The aim of the project is to develop new, fast and non-invasive methods to evaluate hemodynamic changes and individual pharmacological terlipressin response in patients with acute hepatorenal syndrome (type HRS-AKI) We expect a higher increase in renal blood flow in terlipressin-responders compared to terlipressin-non-responders and non-responders will generally have a lower basic renal flow and a decreased cardiac output. Study design and patients The study design is experimental and includes 30 cirrhotic patients with HRS-AKI. Patients with HRS-AKI are MR scanned before and 17 minutes after their first dose of terlipressin. ECHO is performed before first dose of Terlipressin and is repeated after one of the first doses of terlipressin. Clinically efficacy is defined in accordance to international guidelines at day-7 and 90 days mortality is registered. The screening period and treatments follow international and national guidelines for acute renal failure in patients with cirrhosis.
The aim of the study is to demonstrate the superiority of bariatric surgery on the disappearance of NASH without worsening of fibrosis in comparison to medical standard treatment in obese patients (35 kg/m² > BMI ≥ 30 kg/m²) with NASH complicated of advanced fibrosis (F3 and F4 fibrosis grade according to Brunt score).
The study evaluates whether sarcopenia influences the prevalence of abdominal hernias in patients with cirrhosis.
All patients presenting to the emergency department of Institute of Liver and Biliary Sciences with known cirrhosis and hepatic encephalopathy with grade II will be included in the study. The patient will be randomized into one of the two arms of lactulose or polyethylene glycol. The patient on the lactulose arm will be administered 20 to 30 g of lactulose orally or by nasogastric tube (3 or more doses within 24 hours ) or if oral intake was not possible or inadequate. The Dose will be repeated to ensure 3-4 loose motions per day. The Polyethylene Glycol group will get 17 gm of PEG (Polyethylene Glycol) administered orally or via nasogastric tube. PEG (Polyethylene Glycol)will be administered in 3-4 doses in 24 hours to ensure 3-4 loose stools per day.
This Phase 1b/2a, randomized, double-blind, placebo-controlled study was designed to evaluate the safety, tolerability, and pharmacodynamics of SYNB1020 in hepatic insufficiency and cirrhosis patients with hyperammonemia, with dosing of the investigational medicinal product (IMP) administered in an inpatient unit and subsequent outpatient follow-up for SYNB1020 clearance in two study parts.
Liver cirrhosis is a chronic disease characterized by a progressive accumulation of fibrosis, loss of liver function and portal hypertension leading to several hemodynamic changes.The exact pathophysiological mechanisms causing the hyperdynamic alterations in cirrhosis are not fully elucidated. Aim: The aim of the study is to assess hemodynamic alterations in liver cirrhosis by non-invasive MRI and echocardiography compared to portal hypertension measured with liver vein catheterization (HVPG, hepatic vein pressure gradient). Furthermore, the aim is to explore hemodynamic differences between cirrhotic patients and healthy subjects. Study design and cohort: The study has a cross-sectional design and a cohort with 99 patients with liver cirrhosis - with and without complications and 27 healthy volunteers. The patients are recruited at the Gastrounit Hvidovre University Hospital. The day before the first visit patients are hospitalized and fasting overnight. At first visit liver vein catheterization (LVC) and echocardiography are performed. Second visit must be performed within 4 weeks after first visit. At the second visit patients are fasting minimum 6 hours before having MR-flow scanning, cardiac-MR and MR-Elastography (MR-E). The healthy volunteers are only offered MR-flow scanning, cardiac MR and MR-E as well as urine- and blood tests Follow-up for liver-related clinical outcome and mortality in medical records
To validate the ability of the Methacetin Breath Test (MBT) to detect clinically significant portal hypertension (CSPH)/severe portal hypertension (SPH) defined as hepatic venous pressure gradient (HVPG) ≥ 10 mmHg and HVPG ≥ 12 mmHg respectively, in patients with non-alcoholic steatohepatitis (NASH) during the course of treatment with Conatus's investigational product emricasan/placebo.
