Effect of Preoperative Supplementation in Insulin Resistance
Liver DiseaseTo elucidate the effect of preoperative supplementation of carbohydrate and branched-chain amino acids on postoperative insulin resistance in patients undergoing hepatic resection, we set a randomized trial.
Effect of Omega-3 PUFA Supplementation in NAFLD Patients
Non-Alcoholic Fatty Liver DiseaseThe purpose of this study is to determine whether dietary supplementation with omega-3 polyunsaturated fatty acids will decrease the amount of fat in liver.
Effects of Macronutrients on Hepatic Lipids, Plasma Triglycerides, and Insulin Sensitivity
Metabolic Syndrome XLiver DiseasesThe purpose of this study is to assess how the macronutrient composition of the diet effects lipid and glucose metabolism intrahepatic lipids insulin sensitivity in healthy lean subjects and in subjects with a high metabolic risk (ie overweight and offsprings of patients with type 2 diabetes mellitus).
Phase I Trial of Silymarin for Chronic Liver Diseases
Hepatitis CNon-Alcoholic Fatty Liver DiseaseThe purpose of this study is to determine the safety and tolerability of different dosages of silymarin on subjects with Hepatitis C or Non-Alcoholic Fatty Liver Disease.
Postprandial Lipotoxicity and Nonalcoholic Fatty Liver Disease
Nonalcoholic Fatty Liver Disease (NAFLD)Nonalcoholic fatty liver disease (NAFLD) is mainly considered a nutrition-related disease and life-style/diet interventions showed some promising results. But in spite of this, there are no available markers to efficiently guide interventions. the hypothesize put farth by the investigators is that NAFLD patients develop postprandial abnormalities of plasma lipids upon "western diet" challenge, more severe in steatohepatitis (NASH) than in pure steatosis (NAFL), promoting liver injury. Our study aims to evaluate the presence of toxic lipids (such as free-fatty acids, ceramides, diacylglycerols, sphingolipids) in postprandial state after ingestion of a "western diet" in NAFLD patients. Consecutive patients (group 1: NAFL patients; group 2: NASH patients) with biopsy-proven NAFLD (liver biopsy < 6 months) will be recruited during a period of 12 month. Blood samples will be drawn at fasting, 2hours, 4hours, 6hours and 8hours after ingestion of a "western diet" meal. Plasma lipid profiles using lipidomics, circulating markers of liver injury and inflammation will be analyzed. the investigators will also assess the hepatotoxicity of plasma from NAFL or NASH patients in-vitro.
A Study to Evaluate the Pharmacokinetics of ACT-541468 in Subjects With Mild, Moderate, and Severe...
Hepatic ImpairmentThis is a prospective, single-center, open-label, single-dose, Phase 1 study, to assess the effect of mild, moderate, and severe hepatic impairment due to liver cirrhosis on the pharmacokinetics of ACT-541468.
Feasibility of VIIT in Adults With NASH
Nonalcoholic Steatohepatitis (NASH)Nonalcoholic Fatty Liver2 moreThe purpose of this study is to determine whether patients with stage 1-3 NASH-related fibrosis are able to complete a single vigorous-intensity interval training (VIIT) session on an indoor rowing machine and provide blood samples before and afterwards. The results of this study will provide the foundation for future research on the role of VIIT in treating NASH.
Ischemic Preconditioning at a Distance in Liver Surgery
Liver DiseasesDuring hepatic transection, it exists a high risk of perioperative blood loss. The haemorrhage and its consequences (hypovolemia and blood transfusion) might impact the short and long term morbidity The vascular control by hepatic pedicle clamping (Pringle's maneuver) or total hepatic vascular exclusion, helps minimizing blood loss and leads to a more extensive hepatic resection. Side effects of vascular control result of ischemia-reperfusion injury (IRI) : these reperfusion lesions results of different mechanisms than those responsible for the ischemic one. IRI cause lesions and postoperative dysfunction of the remaining liver. Among strategies to reduce the adverse effects of IRI : ischaemic preconditioning (IPC) has been described. It can be either mechanical (intermittent hepatic pedicle clamping) or pharmacological (sevoflurane inhalation). Short intermittent vascular occlusions in a organ might produce a resistance to a longer ischaemic period. It is certainly a physiological organ adaptation to tissue hypoxemia, which has a therapeutic potential when targeted. During liver resection, ischaemic preconditioning is realised with periods of hepatic pedicle clamping and unclamping. It decrease morbidity and mortality and prevent postoperative hepatocellular insufficiency due to clamping and IRI at day 5. Ischaemic preconditioning may also be applied remotely. Indeed, it is shown that short ischaemic periods in a target organ can also have a protective effect on distant others. This mechanism involve three signalling pathways : neuronal , humoral and systemic pathways. In a previous randomized study, Kanoria and al, demonstrated that the remote ischaemic preconditioning group has shown significant lower rates of serum transaminases and higher liver clearance (spectrophotometry method) than the control group. A latest study, measuring postoperative prothrombin rates has shown improved liver recovery due to halogen agents such as sevoflurane.
Effects of Carnitine Supplementation on Liver and Muscle
Non-Alcoholic Fatty Liver DiseaseInsulin ResistanceIt will be evaluated whether carnitine, a dietary supplement, reduces liver fat and improves metabolism in individuals who have a high concentration of fat within their liver. Participants will be given either Carnitine or placebo, together with a meal replacement milkshake twice daily for 6 months.
Study to Estimate the Effects of Hepatic Impairment on the Pharmacokinetics (PK) of PF-07321332...
Hepatic ImpairmentThe study is to estimate the effect of hepatic impairment on the plasma PK of PF-07321332/ritonavir. Findings from this study will be used to develop dosing recommendations so that the dose and/or dosing interval may be adjusted appropriately in the presence of hepatic impairment.
