Active clinical trials for "Liver Cirrhosis"

Background: The XL probe of FibroScan was recently developed to realize liver stiffness measurements (LSM) in overweight patients. Severe obese patients have a high prevalence of liver injuries and could benefit of liver evaluation prior to bariatric surgery. Objectives: Assess the FibroScan applicability, reliability and diagnostic performances in severe obese patients' candidates for bariatric surgery.

This is a multi-center study to prospectively gather clinically-characterized plasma samples to determine the diagnostic performance characteristics (sensitivity and specificity) of the HCCBloodTest among patients with cirrhosis with and without HCC

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

Exocrine pancreatic insufficiency (EPI) is the inability of the pancreas to perform a normal digestive function. The prevalence of IPE in patients with decompensated hepatic cirrhosis (HC) is unknown and most published series are short, old and use a single diagnostic technique with potential risk of false positives and negatives. Demonstrating IPE in a patient with HC can change their vital prognosis with the indication of pancreatic enzymes that can improve their nutritional status and help control their decompensations. Objectives: To assess the prevalence of IPE in patients with decompensated CH. To establish correlation between fecal elastase and 13C triolein breath test. Methodology: Unicentric, transversal study that will be carried out during hospitalization. Patients with HC who enter for decompensation and requiere hospitalization will be included consecutively. Exclusion criteria will include prior diagnosis of IPE, suspicion of biliary obstruction, more than 5 dep / d induced by laxatives or liquid stools. The diagnosis of IPE will be made with the combination of two techniques (13C triolein breath test and fecal elastase). Demographic, epidemiological data, clinical data as well as anthropometric parameters will be collected. A blood test will also be done to assess nutritional status and associated deficits. A multivariate analysis will be performed to assess the predictive factors of IPE

The existence of an adipose tissue microbiota causally involved in the triggering of a low grade inflammation could resemble what observed in liver fibrosis. To generate microbial hypotheses putatively responsible for the onset of liver fibrosis we sequenced the 16SrDNA gene from liver biopsies from 36 obese patients (ROLIVER cohort) and describe an original mathematical approach to decipher signatures of early stage of liver fibrosis F0, F1, F2.

Retrospective study of all patients diagnosed with primary biliary cholangitis during January 2001 to July 2016 at West China Hospital by review of medical records. The following variables will be retrospectively studied: age, sex, first symptoms, clinical characteristics, pathology, treatment, stage, complications of cirrhosis, other autoimmune diseases and long-term outcome.

Prospective multicenter cohort recruiting consecutive patients from 7 hospitals in Andalusia, southern Spain, according to following criteria: 1) HIV infection, 2) Chronic active HCV infection, 3) Older than 18 years, 4) New diagnosis of liver cirrhosis on the basis of a liver stiffness above 14 kiloPascals, 5) No previous or concomitant decompensation of liver disease. Patients are prospectively followed-up according to a uniform protocol of care. Epidemiological, clinical and laboratory variables are periodically recorded. The primary outcomes are the emergence of a liver decompensation (including hepatocellular carcinoma), liver transplant or death. The predictors of these outcomes are analyzed.

Cirrhotic patients are patients with high morbidity and mortality, it is very important for determining the prognosis of these patients. The importance increases when these patients waiting for a liver transplant. The Model for End-Stage Liver Disease (MELD) is a reliable measure of mortality risk in patients with end-stage liver disease. It is used as a disease severity index to help prioritize allocation of organs for transplant. MELD uses the patient values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival. Blood tests that we use today in daily practice to evaluate the coagulation system (PT, PTT) do not check actually the functioning of the system, but examine the level of clotting factors and therefore only verify that the side of Anticoagulant of the equation and not the side of the procoagulant . To examine the coagulation system function tests have been developed, One of them is the thrombin generation. The purpose of the trial is to determine whether thrombin generation test can be a prognostic indicator in patients cirrhosis.

We hypothesize that individuals with Alpha-1 Antitrypsin (AAT) deficiency have ongoing liver injury which is not detected by the usual blood tests used to look at liver function. This ongoing liver injury leads to cirrhosis in a significant number of adults with AAT deficiency.

The investigators wish to determine the lumped constant (LC), which is a correction factor necessary for converting measurements of hepatic FDG metabolism (measured by PET) to those of regular glucose in patients with cirrhosis and healthy subjects. Working hypothesis LC for FDG in liver tissue is not significantly different from unity in healthy subjects LC for FDG in liver disease is significantly different from LC in healthy liver Insulin changes the LC for FDG in liver tissue, but not by the same factor in liver disease and healthy subjects.
