Filter by:This is a multicenter, double-blind, randomized, placebo-controlled trial involving subjects with a diagnosis of "definite NASH" with fibrosis (excluding cirrhosis) as determined by the central histopathologist. Upon successful screening, subjects will be randomized to receive either emricasan 50 mg BID or emricasan 5 mg BID or matching placebo BID.
To examine the quality of liver images produced when the contrast agent Eovist is used during MRI.
Chronic liver diseases are common and the two main causes in France are NAFLD (No Alcoholic Fatty Liver Disease Nonalcoholic) and ALD (alcoholic liver disease). Because of the importance of the current global obesity, NAFLD has become very common and it is estimated that its prevalence in the general population reaches 20-30%. NAFLD (No Alcoholic Fatty Liver Disease Nonalcoholic) and ALD (alcoholic liver disease) includes a broad spectrum of liver damage, ranging from simple steatosis isolated (infiltration of fat in the liver), in hepatic inflammation, fibrosis (abnormally high accumulation of extracellular components in the functional liver tissue) and finally cirrhosis and its complications. Choline deficiency (essential nutrient generally classified as Class B vitamins) has been associated with liver damage each characterizing NAFLD and ALD. The amount of choline in the body depends in particular on food intake and degradation of choline by the intestinal microbiota. NAFLD and ALD are complex pathologies resulting from the interaction of environmental / nutritional factors and a genetic background. It therefore appears now necessary to study the influence of the relationship between genetic predisposition, environmental factors, and gut microbiota metabolism of choline on the severity of liver injury observed in NAFLD and ALD. If the interaction of these three elements (the host genetics - environmental factors - and intestinal microbiota metabolic choline) has an influence on the severity of the lesions of NAFLD and ALD direct application may be of bring a food supplement choline in patients at risk (mutation of the PEMT gene (phosphatidylethanolamine N-methyltransferase), postmenopausal women, microbiota profile for increased degradation of dietary choline) to restore the amount of choline in the body and thus to avoid a worsening of the ALD or NAFLD and progression to cirrhosis.
The PROP UP research study is funded by The Patient Centered Outcomes Research Institute (PCORI). PROP UP is a multi-centered prospective observational study that will evaluate all-oral treatment regimens for chronic hepatitis C viral (HCV) infection regarding several patient-reported outcomes (PROs) such as HCV-associated symptoms, treatment side effects, medication adherence, out of pocket costs, comorbid conditions, and long-term benefits of cure and harms of treatment to compare PROs of different treatment regimens, treatment durations, and patient subgroups. Participants will be recruited from 9 U.S. liver centers. Approximately 1920 patients with HCV infection who are prescribed a regimen containing Sofosbuvir/Ledipasvir(SOF/LED), SOF/Velpatasvir(SOF/VEL), Grazoprevir/Elbasvir(GRZ/ELB), OBV/PTV/r + DSV (PRoD), or daclatasvir/SOF (DAC/SOF) will be recruited and approximately 1600 patients who are approved and begin HCV treatment will be enrolled in the longitudinal study. PRO surveys will be evaluated before, during and after HCV treatment. PROP UP is a collaborative effort between behavioral and biomedical researchers, a patient engagement group and a patient advocacy organization.
The purpose of this study is to investigate the clinical value of enhanced recovery after surgery protocal in laparoscopic hepatectomy by assessing its outcomes and hospital stay days comparing with traditional care .
This study plans to learn more about a new test to look at liver function, the HepQuant-Shunt (HQ-Shunt). The HQ-Shunt is being evaluated for safety and effectiveness as an alternative to Hepatic Venous Pressure Gradient testing in patients with liver disease.
Background: Metabolism refers to the many chemical pathways by which various compounds, including food, are processed and used in the body. People with non-alcoholic fatty liver disease (NAFLD) have too much fat in their liver cells, but what causes it is unclear. One explanation is that people with NAFLD process food and metabolize it differently than people without NAFLD. Researchers want to compare how food is metabolized in people with and without NAFLD. Objective: To better understand how food intake influences the development and progression of NAFLD. Eligibility: People ages 18 and older with NAFLD or with a non-NAFLD metabolic syndrome Healthy volunteers ages 18 and older Design: Participants will be screened with medical history, surveys, physical exam, and blood tests. This will have ultrasound of the abdomen. This uses sound waves to image internal organs. Participants will stay at the Clinical Center for 2 nights. They will fast he first night. On the second day they will: Have their metabolism monitored in a metabolism research room for 24 hours Have a catheter inserted into an arm vein for several blood tests Drink an Ensure Plus for breakfast Have solid meals for lunch and dinner Have several urine tests. The final morning, they will: Have more blood tests. Have a DXA test to measure the fat in the body. They will lie on their backs for 15-25 minutes while an x-ray machine is positioned over areas of the body.
Background: It is still difficult to predict the outcome in patients requiring Fontan Revisions and in those who have evidence of congestive hepatopathy and probable cirrhosis requiring major cardiac surgery including heart transplant. Over the years, many prognostic indices have been derived from laboratory results of blood tests, clinical and physiological variables (or some combination thereof), from liver imaging to liver histology, which has issues of sampling error, medical risks and technical difficulty. None of these have proved entirely satisfactory. Predicting morbidity or survival is particularly important when deciding about Fontan revisions versus the need for heart transplantation. What is needed here is a truly reliable test of liver function that can help predict outcome, on the basis of a single measurement within few days of a planned revision. For this purpose, it is desirable that the chosen tests of liver performance be safe, non-invasive, easy to perform, have a rapid turnaround for results, and be readily repeatable. Tests of hepatic elimination of various exogenous substances have been described, such as galactose elimination capacity (GEC), indocyanine green (ICG) clearance, lidocaine metabolism to monoethylglycinexylidide (MEGX), and other tests that rely on liver metabolic capacity. None of these metabolic or clearance tests achieved widespread acceptance or use, mostly because their performance and analyses were cumbersome. HepQuant,LLC has developed a platform of tests of liver function which include Systemic Hepatic Filtration Rate (HFR), Portal HFR, SHUNT, and Disease Severity Index (DSI)1,2. HepQuant tests specifically target the hepatic uptake of cholate and use a single noninvasive test of 90 minutes duration to quantify the systemic circulation, portal circulation, and portal-systemic shunt and to derive a DSI in intact human subjects. HepQuant tests can assess all stages and etiologies of liver disease. In chronic HCV patients HepQuant testing can predict which patients will respond to antiviral therapy and can measure the improvement in hepatic function that occurs after successful antiviral therapy. Patients who did not respond were followed for an average of 5 years and up to 8 years, and baseline HepQuant testing could predict clinical outcomes (CTP progression, variceal bleeding, encephalopathy, ascites, liver-related death) with 87% sensitivity and 71% specificity.
This is an open-label, non-randomized trial that will be conducted at two clinical sites, Thomas Jefferson University (TJU) and the Hospital of the University of Pennsylvania (HUP). Enrolled patients undergoing trans-jugular liver biopsy with hepatic vein pressure gradient (HVPG) measurements will receive a continuous infusion of Sonazoid® (GE Healthcare, Oslo, Norway) co-infused with 0.9% NaCl solution over a 5-10 minute time period. Ultrasound imaging will be performed using a Logiq 9 scanner with a 4C transducer (GE Healthcare, Milwaukee, WI) and the novel SHAPE (subharmonic aided pressure estimation) algorithm will be used to measure pressure values in the hepatic and portal veins. Data will be stored on a PC and compared to pressure-catheter measurements, Subjects identified in the initial examination as having portal hypertension (by HVPG results) will be monitored by SHAPE for up to 18 months. These subjects typically have surveillance Computed tomography (CT) or magnetic resonance imaging (MRI) scans every 6 months to screen for liver cancer, and at those times a repeat SHAPE examination will be performed (ideally within 1 month of their clinically indicated imaging follow up appointment). In patients who undergo more frequent screening (generally 3 month intervals), SHAPE exams will be performed at 6 month intervals. Any repeat trans-jugular liver biopsies performed in this population will also trigger a repeat SHAPE study. Results of blood test evaluations (performed every 3 months in this population), medication, concomitant imaging study or procedure (including endoscopies) will be noted (all blood tests and imaging are clinically indicated only and are not required by this protocol). The end point for this part of the study will be any one new complication (e.g., liver cancer) or a marked worsening in any complication, liver transplantation, death, or the end of this clinical trial (after 3 years). The investigators expect these patients will be monitored three times during the course of this clinical trial. The time to reach the end point will be noted if a new complication or a marked worsening in any complication occurs.
This study plans to learn more about transfusion of a human blood component called plasma in patients who have liver problems. Patients are asked to be in this study because they have liver disease and therefore may require the transfusion of plasma. The dose of plasma required to reach certain blood clotting laboratory targets is usually determined by clinicians. Due to the complexity of the patient's blood clotting disorder, determining the appropriate dose of plasma is very difficult. The investigators have developed a dosing table based on information from other patients with liver disease and the investigators are testing it to see if it is a more accurate dosing tool then clinician chosen dosing of plasma in patients with liver disease who need one or more plasma transfusions
