Active clinical trials for "Non-alcoholic Fatty Liver Disease"

The purpose of this study is to evaluate how the liver receives and uses fats for energy. This will help the investigators further understand the physical and chemical processes responsible for Non-Alcoholic Fatty Liver Disease (NAFLD) in overweight females with or without NAFLD who are scheduled to undergo gastric bypass surgery.

The purpose of this research is to further study the effect weight loss after gastric bypass surgery has on the heart and blood pressure and on how the body uses or metabolizes the sugars, fats and proteins we eat. Additionally, the researchers want to study fat tissue for gene patterns which may be responsible for where we carry fat on our bodies, as well as look carefully at a possible link between adipose tissue and insulin resistance. The researchers also want to evaluate the liver for the presence of fatty liver, which is common in people with obesity and is associated with insulin resistance, as well as study the liver for gene patterns which may be associated with non-alcoholic liver disease. Evaluating cardiovascular function and endocrine function before and after gastric bypass surgery, as well as studying adipose and liver tissue may help us understand the link between obesity, insulin resistance, fatty liver disease, high blood pressure and health problems such as diabetes and heart disease. Consequently, this may help in the future by identifying those who will benefit most from gastric bypass surgery.

A post-treatment follow-up observational study for liver disease subjects with or without liver cirrhosis after receiving emricasan or placebo. Subjects must have been enrolled in a prior IDN-6556 study to be eligible.

This study investigates the relation between the gastrointestinal tract bacteria and the progression of fatty liver disease .

Background: - Non-alcoholic fatty liver disease is the most common form of liver disease in the United States. It includes many conditions. Researchers want to study fatty liver disease by looking at people who have liver cirrhosis. They also want to look at people who are or were listed for liver transplants. Genetic studies may provide more information on the causes of these conditions. Objectives: - To study possible genetic causes of non-alcoholic fatty liver disease. Eligibility: - Individuals of any age who have non-alcoholic fatty liver disease and related conditions. Design: Participants will be screened with a physical exam and medical history. Participants will provide a blood sample for genetic testing. Liver tissue from a transplant or biopsy may also be studied. Participants may also be asked to have an imaging study of the liver. This imaging study may be an x-ray or magnetic resonance imaging. No treatment will be provided as part of this research study.

The aim of this project is to generate pilot data for a grant proposal to evaluate the impact of intermittent cold exposure (ICE) on brown and white adipose tissue (BAT/WAT) function in children with non-alcoholic fatty liver disease (NAFLD). The condition NAFLD is the most common liver disease in both adults and children. There are many emerging drug therapies for NAFLD but at considerable cost in terms of potential side effects. In a mouse model of diet-induced obesity, ICE was shown to help activate BAT, which may help NAFLD and other obesity associated health risks. Given that children have more BAT than adults, we hypothesise that intermittent cold exposure via a cooling vest in children with NAFLD will increase BAT stores or function. We will investigate whether intermittent cold exposure via a cooling vest device will stimulate BAT and also establish whether the cooling vest is acceptable to children and young people. If it is acceptable and has an impact on BAT function this could be a new treatment to reduce the severity of metabolic disorders associated with obesity, particularly fatty liver, e.g. hepatic steatosis. In stage 1, we will investigate the impact of intermittent cold exposure (ICE) on brown and white adipose tissue (BAT/WAT) function in young people aged 16 to 26 years old, as a feasibility study to optimise the cooling process. In stage 2, we will investigate the impact of ICE on BAT and WAT function in 8-16 year olds with non-alcoholic fatty liver disease (NAFLD) and matched controls. Participants will have thermal imaging, MRI scans and provide samples before and after wearing the cooling vest.

Non-alcoholic fatty liver disease (NAFLD) covers a spectrum from simple reversible hepatic steatosis to inflammation and fibrosis termed steatohepatitis (NASH). The mechanisms behind why some subjects progress from NAFLD to NASH are not clear and the responsible mechanism for storage of excess amounts of liver fat in patients with NAFLD are poorly understood. Patients with type 2 diabetes mellitus (T2D) and abdominally obese subjects very often have accumulation of liver fat (NAFLD). T2D is also associated with abnormal lipid metabolism (dyslipidemia), including free fatty acids (FFA), hypertriglyceridemia and excessive postprandial hyperlipidemia which increases the risk of ischemic cardiovascular disease (CVD) and heart failure. In healthy, insulin sensitive subjects the postprandial increase in triglycerides (TG) is primarily caused by meal derived chylomicrons, whereas endogenously produced TG (VLDL-TG) and decreased peripheral TG clearance only becomes quantitatively important in insulin resistant subjects .Thus, postprandial lipidemia in T2D results from both chylomicronemia as well as a reduction in both insulin mediated suppression of VLDL-TG secretion and lipoprotein lipase (LPL) mediated peripheral clearance. A recent study demonstrated that the ability of insulin to suppress hepatic VLDL-TG after a fat-enriched meal and the duration of the postprandial hyperlipidemia was similar in patients with T2D compared with age- and BMI matched individuals without T2D, indicating that the degree of insulin mediated VLDL-TG secretion and hyperlipidemia primarily depends on insulin sensitivity and not the presence of T2D diabetes per se. In these studies, the investigators want to examine the effect of a fat enriched mixed-meal on hepatic VLDL-TG handling and adipose storage capacity in patients with T2D with and without NAFLD. Investigators will address these questions using carboxyl-14C triolein labeled VLDL-TG, magnetic resonance (MR) spectroscopy of liver, muscle and fat biopsies in combination with state-of-the art muscle and adipose tissue enzyme kinetics, gene- and protein expression. The overarching goals are to define abnormalities and differences between patients with T2D with and without NAFLD in terms of hepatic lipid metabolism.

This study aimed to observe whether a hydrolyzed oyster extract improves liver health in participants whose alanine transaminase (ALT) levels are1-3 fold above the normal. A total of 96 participants will be randomly allocated to active (oyster) or placebo group (1:1). Each group will receive 750 mg of oyster extract or placebo per day for 8 weeks. Primary outcome will be the change in ALT level and secondary outcomes will be; (1) ratios of participants with normal ALT, aspartate aminotransferase (AST), and gamma-glutamyl transferase (GGT); (2) the change in serum bilirubin; (3) the change in multi-dimensional fatigue inventory; (4) the changes in serum lipids; (5) the changes in antioxidant enzymes.

A 2 x 2 cross-over dietary intervention trial designed to investigate the effects of low glycemic index (LGI) versus high glycemic index (HGI) diet on hepatic fat accumulation and gut microbiota composition in participants with NAFLD. Participants will be allocated randomly to a 2-week either high GI (HGI) or low GI (LGI) diet followed by a 4-week wash-out period and then the LGI or HGI diet, opposite to the first 2-weeks (N= 16).

A research study of a compound containing vitamin E, silymarin and carnitine, three over the counter supplements. The investigators hope to learn if the new supplement can safely and successfully treat fatty liver disease or Non Alcoholic Fatty Liver Disease (NAFLD).
