Nonalcoholic fatty liver disease (NAFLD) is the most common cause of abnormal liver biochemistry tests in the world. The prevalence rate of NAFLD has been reported to be 30-40% in men and 15-20% in women, up to 70% of people with type 2 diabetes mellitus (Type 2 DM) and even surpassing 74% to 90% of morbidly obese patients with body mass index (BMI) higher than 35 kg/m\^2. The primary aims of this prospective cohort study would evaluate the predictive factors of successful weight reduction, NAFLD and nonalcoholic steatohepatitis (NASH) improvement in a large cohort of morbidly obese patients undergoing bariatric surgery. Secondarily, the diagnostic accuracy of noninvasive serum markers, doppler ultrasonography and transient elastography would be validated. Thirdly, we would conduct gene expression analyses to elucidate biological pathways underlying NAFLD phenotypes in this unique cohort.
NCT03583437
Non-alcoholic fatty liver disease (NAFLD) covers a spectrum from reversible hepatic steatosis to inflammation and fibrosis termed steatohepatitis (NASH) and cirrhosis. New evidence indicates that NAFLD is associated with development of heart failure, abnormal ventricular glucose and fatty acid (FA) utilisation and cardiosteatosis. The mechanisms behind cardiac involvement and the progression from NAFLD to NASH are poorly understood but must include altered cardiac and intrahepatic lipid handling. In collaboration with renowned research groups from Oxford, Mayo Clinic and Copenhagen investigators plan comprehensive kinetic studies of heart and liver FA uptake and oxidation, ventricular function and substrate utilisation, and hepatic triglyceride (TG) secretion in order to assess mechanisms governing cardiac and hepatic lipid and glucose trafficking in subjects with NAFLD and NASH and the relationship with heart function. In addition, the investigators will assess skeletal muscle and adipose tissue enzyme activities, gene expression and protein concentrations in these subjects to define mechanisms involved in the cross-talk between heart, liver, muscle and adipose tissues. Investigators will address these questions using innovative tracer techniques (11Cpalmitate, 11C acetate, 18FDG glucose PET tracers and TG tracers) in combination with hepatic vein catherisation to study cardiac and liver substrate trafficking, as well as NMR spectroscopy, echocardiography, muscle and fat biopsies in combination with state-of-the art muscle and adipose tissue enzyme kinetics, gene- and protein expression. Effects of acute exercise will be assessed. The overarching goals are to define abnormalities and differences between NAFLD and NASH in hepatic lipid (FA and TG) metabolism and to assess the effect of exercise on both hepatic, cardiac and adipose and skeletal muscle lipid and substrate utilisation.

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.
NCT02217345
Nonalcoholic fatty liver disease (NAFLD), fatty infiltration of the liver in the absence of alcohol use, is an increasingly recognized complication of obesity, with prevalence estimates of about 30% of individuals in the United States. A subset of these will develop progressive disease in the form of nonalcoholic steatohepatitis (NASH), which can progress to cirrhosis and liver failure. NAFLD is expected to be the most common indication for liver transplantation by the year 2020. We hypothesize that growth hormone (GH) replacement will decrease intrahepatic lipid accumulation as quantified by 1H magnetic resonance spectroscopy (1H-MRS).
NCT00983463
Nonalcoholic fatty liver disease (NAFLD) is the most common type of liver disease in the United States. The incidence of NAFLD is very similar to that of obesity, type 2 diabetes, and the metabolic syndrome. The investigators hypothesize that there may be a relationship between over-nutrition, decreased physical activity and the development of fatty liver. The purpose of this study is to identify the types of fats and proteins, and the quantity of each, that are associated with increased severity of NAFLD.
NCT00771108
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.
NCT05035043
To determine the economic burden of NAFLD (Non-Alcoholic-Fatty-Liver Disease) patients in Belgium, Flanders by means of a bottom-up approach.
NCT04925362
The main objective of this cohort study is to determine genetic, clinical biologic and metabolic factors associated with patient heterogeneity in regards to severity of NAFLD at diagnosis as well as during the clinical course. * at diagnosis, with the aim to better characterize patients of different severity and improve our understanding of clinical and histological heterogeneity at diagnosis * during the clinical course to better understand and predict disease progression in terms notably of fibrosis progression and progression to cirrhosis
NCT03534908
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the world. NAFLD is associated with a lot of comorbidity, such as diabetes, metabolic syndrome, coronary heart disease and chronic kidney diseases. However, the correlation between the NAFLD and cardiovascular disease (CVD) events remains controversial. This study is an observational study based on a big retrospective cohort in china to explore the prevalence of NAFLD in China, the risk factors associated with NAFLD, as well as whether patients with NAFLD are more prone to experience CVDs and CVD events.
NCT06357052
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease, ranging from pure steatosis to non-alcoholic steatohepatitis and ultimately to liver cirrhosis. In order to study the association between NAFLD and nephrolithiasis while minimizing the confounding effect of metabolic syndrome, we investigated the impact of different degrees of NAFLD severity on potential risk factors for stone formation.
NCT07051863
The goal of this observational study is to establish a unified cohort for retrospective and prospective high quality baseline and follow-up data registration of patients with a diagnosis of NAFLD/NASH/MAFLD, according to standardized criteria. This will allow future studies aimed at elucidate clinical presentation, natural history, response to treatment, genetic and metabolic risk factors, treatment options and outcomes of the disease. The cohort will allow investigators to carry out genetic, serological, microbiologic and immunological studies.
NCT02754037
The goal of this study is to evaluate non-invasive imaging techniques for determining liver steatosis (fat), inflammation (abnormal tissue swelling), and fibrosis (abnormal tissue scarring).In addition, the study group will be using other test measures including personal demographics, laboratory blood test results, and imaging measurements to determine the severity of NAFLD (non-alcoholic fatty liver disease), NASH (non-alcoholic steatohepatitis), inflammation, and fibrosis.

NCT01418027
The prevalence of NAFLD is 50-70% in obese people. A decrease of calorie intake and increase of physical activity are recommended as an effective approach for the prevention and treatment of NAFLD. However, the exercise model for NAFLD intervention is understudied. In the present study we aim to compare the effect of intensive and conventional exercise interventions on NAFLD.
NCT02098317
Non-alcoholic fatty liver disease (NAFLD) has reached epidemic proportions and is rapidly becoming the one of most common causes of chronic liver disease in children. The pathogenesis of NAFLD is generally considered the result of a series of liver injuries, commonly referred as "multi-hit" hypothesis. Several studies suggest that inflammatory pathways and oxidative stress could be responsible of disease progression. The purpose of this interventional study is to evaluate the efficacy and tolerability of docosahexaenoic acid (DHA) and Vitamin D in children and adolescents with biopsy-proven nonalcoholic fatty liver disease (NAFLD).
NCT04779905
Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. This disease reportedly affects up to 30% of the general population in Western countries, especially in patients with metabolic syndrome, obesity, and type II diabetes. NAFLD is considered to be an independent risk factor for cardiovascular disease and there is accumulating evidence to support a causative role in the development of chronic kidney disease (CKD). So, we aim first to assess the prevalence of chronic kidney disease in NAFLD patients, secondly to detect the association between hepatic fibrosis and CKD in NAFLD patients
NCT01677325

Non-alcoholic Fatty Liver Disease (NAFLD) refers to a spectrum of disease characterized by the presence of more than 5% of steatosis in hepatocytes of individuals who consume little or no alcohol. It ranges from simple steatosis without evidence of inflammation, to the association of steatosis and inflammation with cellular necrosis, the so-called non-alcoholic steatohepatitis (NASH). NAFLD has become increasingly common in developed countries affecting up to 38% of the population. It is mostly but not exclusively associated with metabolic syndrome including obesity, insulin resistance, and hypertension. There is growing evidence of a close interaction between the gut and the liver "Gut-liver axis", particularly in the pathogenesis of NAFLD. The pathophysiological mechanism behind this association is not well understood but involves small intestinal bacterial overgrowth (SIBO), intestinal wall inflammation and increased permeability, all leading to systemic translocation of microbial metabolites including endotoxins and pro-inflammatory markers called Pathogen Associated Molecular Pattern (PAMPs). Thus, the gut-liver interaction, mediated by cytokines and inflammatory proteins seem to be the cornerstone of this complex liver disease. Recent studies underlined the increased prevalence of NAFLD in the Inflammatory Bowel Disease (IBD) population, accounting for almost 32% of hepatic extra-intestinal manifestations of the disease. Several hypotheses have been proposed to explain the pathophysiology behind this association, encompassing chronic intestinal wall inflammation, increased intestinal permeability and altered gut microbiota or dysbiosis. To our knowledge, no studies have been conducted so far to investigate the correlation between intestinal disease activity (IBD flare versus remission state) and NAFLD incidence and behavior (progression versus regression of steato-fibrosis). We therefore aim to conduct a prospective paired study, on IBD patients followed at Saint-Pierre University Hospital, aiming to explore this correlation. In this paired study design, patients will be their own controls over the course of their disease: An evaluation of NAFLD will be done for all patients during both phases of their inflammatory bowel disease: In the active phase and in remission phase. Our primary outcome is to assess NAFLD prevalence in the IBD population followed at our institution. Secondary outcomes will be to explore NAFLD prevalence and behavior (progression versus regression of steato-fibrosis) according to IBD activity, IBD type, IBD duration and types of IBD treatments.

Non-alcoholic hepatic steatosis (NAFLD) is characterised by the excessive accumulation of triglycerides in the liver and is often associated, in the absence of significant alcohol consumption, with insulin resistance and metabolic syndrome with which it shares the most frequent clinical manifestations (hypertension, dyslipidaemia, visceral adiposity, glucose intolerance). Due to the pandemic spread of obesity and diabetes and by virtue of better control of viral hepatitis, NAFLD is the most common cause of liver damage in Western countries with a prevalence of around 20-30% of the general population. The clinical impact of NAFLD in diabetes is considerable and represents a real driver of the major clinical outcomes that impact on the health of the individual, consequently creating a real 'burden of disease' especially in those populations considered to be at higher risk of disease severity. Individuals with diabetes are, in fact, those at greatest risk of developing the clinical sequelae of NAFLD and often do not receive adequate hepatological support and a correct hepatic pathology. In fact, it has been documented in the literature that the presence of diabetes increases the severity of liver damage, bringing the risk of NASH up to 80% and increasing the risk of significant fibrosis to 30-40% of subjects with hepatic steatosis as well as representing an independent predictor for significant fibrosis. Lastly, the increased risk of hepatocarcinoma in subjects with diabetes and NAFLD should not be overlooked, as documented by our group and confirmed in a large Italian case series. In subjects with diabetes, moreover, the presence of NAFLD is not only associated with worse glycaemic control, but also with micro- and macro-vascular complications as well as nephrological and neuropathic complications and increased mortality. Therefore, the possibility of applying the non-invasive fibrosis scores currently available for NAFLD on a large scale, in a population at high risk of progressive liver disease, would make it possible to characterise (a) the true epidemiology of significant fibrosis (F3 or higher); (b) allow primary prevention actions to be carried out by optimising the use of resources or by identifying subjects at greater risk of damage progression; (c) understand, in cases with a long history of disease the true prevalence of clinical outcomes; (d) understand the epidemiology of comorbidities and polypharmacy as a function of significant fibrosis.
