Metabolic Flexibility, Gut Microbiota, Healthy Diet and Exercise in NAFLD on Genetics Base
Non-alcoholic Fatty Liver DiseaseObesityNonalcoholic fatty liver disease (NAFLD) is associated to obesity, metabolic syndrome and genetic predisposition: specific variants of the genes PNPLA3 and TM6SF2 are the most involved. Also biochemical mechanisms that affect the "metabolic flexibility" need to be better clarified. It is known that a dietary intervention, accompanied by a physical personalized training, reduce either the hepatic fat content either insulin resistance. Therefore, the aim of the study is to evaluate "metabolic flexibility" in obese NAFLD subjects taking in account the presence or absence of PNPLA3 and TM6SF2 polymorphism and the histopathological diagnosis of either simple steatosis or nonalcoholic steatohepatitis (NASH). The composition of gut microbiota will be also evaluated. Finally, two distinct healthy dietary profiles accompanied by a personalized physical training, will be tested to comprehend whether and how "healthy diets" could operate in the clinical treatment of NAFLD and related conditions.
How Does Dietary Carbohydrate Influence the Formation of an Atherogenic Lipoprotein Phenotype (ALP)?...
Non-alcoholic Fatty Liver Disease (NAFLD)The hypothesis of this study is that a diet high in sugars will increase abnormalities in blood lipids which are associated with increased cardiovascular disease risk, relative to a diet which is low in sugar. We predict that this potentially adverse effect of dietary sugars on blood lipids will be more pronounced in people with a raised level of stored fat inside their liver, as compared to people with a low level of stored fat.
Treatment for Non-Alcoholic Fatty Liver With Different Doses of Vitamin E
Fatty LiverBackground: Non-alcoholic fatty liver disease (NAFLD) is an excess accumulation of fat in the liver cells. It is associated with obesity, high blood pressure, high cholesterol, and diabetes. Some people with NAFLD only have excess fat in the liver. However, other people may develop a worse form of NAFLD with liver injury and scarring. This form, called non-alcoholic steatohepatitis (NASH), can lead to liver failure, liver cancer, and death. Not much is known about why some people develop NASH and others do not. Lifestyle changes such as diet, exercise, and weight loss can decrease the liver damage in NAFLD. Some studies show that vitamin E can also help treat NAFLD. The dose of vitamin E used in these studies is almost 40 times the recommended amount of vitamin E intake from food. It is unclear whether a lower dose could achieve the same effect. Researchers also want to study how vitamin E works at different doses to treat NAFLD. Objectives: To find out the most effective dose of vitamin E to treat NAFLD. To gain a better understanding of how NAFLD and NASH develop, and predict who will respond to treatment. Eligibility: - Individuals at least 18 years of age with suggestion of non-alcoholic fatty liver disease. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. For the first 12 weeks of the study, participants will meet with a nutritionist. They will have personalized diet and exercise plans. Treatment will be monitored with diaries and questionnaires to fill out at home. Participants will also wear a pedometer to measure physical activity. After the 12-week period, participants will have a full physical examination with the following tests: Blood tests Glucose tolerance tests Imaging studies (DEXA scan and magnetic resonance imaging) Liver and fatty tissue biopsy Two weeks after the tests, participants will start vitamin E treatment. They will take up to two pills a day, taken with fat-containing foods. 4 weeks after starting treatment they will have a repeat full evaluation with imaging tests, blood work, and liver and fat biopsies. Participants who are taking vitamin E will take it for up to 120 weeks. They will have monitoring visits every 8 to 12 weeks. At the end of 120 weeks, they will have another full evaluation, with imaging tests, blood work, and liver and fat biopsies.
Exercise Dose and Nonalcoholic Fatty Liver Disease
Non-alcoholic Fatty Liver Disease (NAFLD)The purpose of this research is to provide a better understanding of how exercise (walking) affects non-alcoholic fatty liver disease (NAFLD) in overweight people. NAFLD, which is common in obese people, occurs when the liver has too much fat.
Effect of Treatment With Insulin Sensitizer on Arterial Properties, Metabolic Parameters and Liver...
Nonalcoholic Fatty Liver DiseaseAbstract Background: Insulin resistance has an important role in the development of nonalcoholic fatty liver disease (NAFLD) and is involved in both pathological processes: hepatic steatosis and atherosclerosis. Therefore, treatment of NAFLD with insulin sensitizers is likely to have a favorable effect towards hepatic steatosis and cardiovascular outcomes. Objectives: The present study investigated the effect of metformin on arterial properties, metabolic parameters and liver function in patients with NAFLD. Methods In randomized, placebo controlled study, 63 patients with NAFLD were assigned to one of two groups: Group 1 received daily metformin; Group 2 received placebo. Pulse wave velocity (PWV) and augmentation index (AI) were performed using SphygmoCor (version 7.1, AtCor Medical, Sydney, Australia) at baseline and at the end of 4-month treatment period.. Metabolic measures and serum adiponectin levels were determined.
Phase 1 Pharmacokinetic Study Of CP-945598 In Patients With NASH
Non-Alcoholic Steatohepatitis(NASH)CP-945598 is a potent and selective Cannabinoid-1 (CB1) receptor antagonist currently being developed for the treatment of obesity. CP-945598 is also being considered as a potential treatment for non-alcoholic steatohepatitis (NASH). This study will investigate the steady-state safety, toleration and pharmacokinetics of multiple oral dose administration of CP-945598. Results will be used to estimate the pharmacokinetic characteristics in NASH patients and underwrite the safety of this compound prior to any further studies in NASH patients.
Treatment of Nonalcoholic Fatty Liver Disease With Probiotics and Prebiotics
Nonalcoholic Fatty Liver DiseaseThe investigators' aim is to determine whether probiotic and prebiotic treatment plus lifestyle advice is more effective in reducing hepatic fat content than lifestyle advice alone in patients with Nonalcoholic Fatty Liver Disease (NAFLD).
Omega-3 vs Very Low Calorie Diet for Liver Size Reduction
ObesityMorbid3 moreA recent review demonstrated that Non-alcoholic fatty liver disease (NAFLD) affects 10-35% of the adult population worldwide, with the prevalence approaching 85-100% in obese populations. Current standard treatment for liver reduction before surgery is the use of a very low calorie liquid diet (VLCLD). Multiple studies have shown that a 2-4 week diet with a VLCD will reduce liver volume, in preparation for surgery. Omega-3 (Ω-3) polyunsaturated fatty acids (PUFAs) have been suggested as a treatment for NAFLD. The primary aim of this study is to compare Ω-3 PUFAs and a VLCLD and their effect on left lobe live size before bariatric surgery.
The Effects of Hesperidin on Biochemical Factors and Hepatic Fibrosis in Nonalcoholic Fatty Liver...
Non Alcoholic SteatohepatitisTo study the effects of Hesperidin supplement on lipid profile, liver enzymes, inflammatory factors and hepatic fibrosis in patients with Nonalcoholic Steatohepatitis (NASH), 50 patients who referred to Gastrointestinal (GI) clinic with steatosis grade 2 and 3 will be randomly allocated to receive placebos or 2 capsules Hesperidin for 12 weeks; both groups will be advised to adherence the investigators' diet and exercise program too. At the first and the end of the intervention, lipid profiles, liver enzymes, some inflammatory markers, and liver fibrosis will be assessed and compared between groups.
