Active clinical trials for "Fatty Liver"

The purpose of this study is to investigate the effect of weight loss rate on liver steatosis, steatohepatitis, fibrosis and cardiovascular risk at different stages before and after bariatric surgery. The investigators also aim to study the short-term effect of bariatric surgery on gastric cholecystokinin levels before and 10 days after the bariatric surgery.

The primary purpose of this study is to evaluate the association between nonalcoholic fatty liver disease (NAFLD) by computed tomography (CT) scan and coronary artery disease (CAD) measured by the calcium (CAC) score among HIV-infected persons.

We hypothesize that exenatide (Byetta), a GLP-1 agonist administered subcutaneously for 24-28 weeks improves liver histology in diabetic patients with biopsy-proven NASH.

Unhealthy lifestyle represents a key element fueling the non-alcoholic fatty liver disease (NAFLD) onset and worsening. The investigators aimed to evaluate the effects of confinement-related lifestyle changes experienced during the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic on NAFLD evolution. A retrospective cohort of NAFLD patients was followed two years before and two years during the pandemic. At three identified time points [baseline (January 2018: T0), intermediate (January 2020: T1), and end of study (January 2022: T2)], anthropometrical, biochemical, nutritional, bioelectrical impedance analysis (BIA) data and non-invasive tools measurements were collected.

Hypothesis of this study is the existence of a relation between parameters measured by FibroScan® FS 502 according to our non invasive method and liver steatosis condition. This proof of concept validation is made up of two steps: Step 1: feasibility study of the method on 10 healthy volunteers Step 2: diagnosis study on 50 healthy volunteers (25 between 18-30 years-old and 25 between 40-65 years-old) and on 25 patients whom cares including an liver biopsy et whom the histological answer is clean steatosis (NAFLD). Experimental procedures consist in: Fibroscan measure, preceded by tracking ultrasonography. liver MRI (for substudy about MRI comparison, in step 2) a blood test for biological assessment of liver functions

There is a significant association between autonomic dysfunction and symptoms experienced by NAFLD patients mediated by increased systemic inflammation and insulin resistance, resulting in deteriorating quality of life of affected patients; fatigue and other symptoms drive worsening autonomic dysfunction in these patients. We aim to describe the severity of autonomic dysfunction (AD) in non-alcoholic fatty liver disease (NAFLD) and the relationship of AD to symptoms experienced by NAFLD patients (such as fatigue, chronic pain, depression, sleep disturbance, and cognitive dysfunction), and to the quality of life of NAFLD patients. We also hope to examine the impact of systemic inflammation and insulin resistance as mediators of manifestations of AD and symptoms experienced by NAFLD patients.

The study searched for answers to two questions: 1-What are the plasma betatrophin levels in subjects with non-alcoholic fatty liver disease and healthy controls. 2. Is there any relationship between plasma betatropin levels and different stage of non-alcoholic fatty liver disease 2.Is there any relationship between plasma betatropin levels and metabolic parameters in subjects with non-alcoholic fatty liver disease.

Several experimental data suggest that gut-derived endotoxin and GM composition can act as a "second hit" or insult to convert hepatic SS to NASH and cause both local hepatic and systemic inflammation.This study's aim is to analyze microbiota diversity, providing information both on intestinal microbial composition and on the metabolic processes linked to them. In addition, we will correlate, for the first time, GM composition to hepatic and white adipose tissue gene expression patterns of interest and serum and fecal markers possibly related to impaired fat storage and inflammation. We aim to provide preliminary data to design future intervention studies with pre- or probiotics or bile acid derivatives to prevent/treat inflammation and fibrosis in NAFLD patients.

Non-alcoholic fatty liver disease (NAFLD) is a common disorder, affecting ~30% of people in the general population and up to 96% of obese individuals. Variations in several genes have been found to be associated with fatty liver, but these associations only explain a small percentage of the risk, and further studies are needed. In many cases NAFLD does not cause serious side effects, but in some individuals it progresses to scarring or hardening of the liver, liver failure, and cancer. The purpose of this research study is to determine if individuals who carry certain genetic variations in a gene related to bile and choline metabolism have an increased risk of fatty liver progressing to fibrosis, or scarring of the liver. This study will also use a new, non-invasive method called the FibroScan® to measure liver fat and liver stiffness. The FibroScan® device is FDA approved for use to measure liver stiffness, but not for the liver fat measurement. However, the FibroScan® instrument is considered a non-significant risk device. Since its induction in Europe and worldwide in 2003, there have been no adverse effects reported with this device.

This is a study to investigate genetic predisposition to hepatic steatosis and the expression of gluconeogenic and lipogenic genes in livers of obese children and adolescents. Hypothesis 1: Common variants recently associated with variation in plasma TG levels identified in Genome Wide Association Studies (GWAS) (such as GCKR, PNPLA3) can affect accumulation of fat and subsequent development of Non Alcoholic Fatty Liver Disease (NAFLD). Gene variants act in additive or synergistic manner with progressive liver fat accumulation per additional risk allele. Hypothesis 2: With increase in hepatic fat content NASH and fibrosis will increase. Furthermore, expression of lipogenic markers (SREBP1c) will increase.
