Filter by:This multicenter, double-blinded, randomized controlled trial aims to evaluate the effect of berberine in reducing visceral and liver adipose tissue among individuals with obesity and non-alcoholic fatty liver disease (NAFLD) in China.
The primary aim of this study is to investigate the acute changes in liver fat content in response to a fixed carbohydrate restriction (i.e. intake of 60g/day or 70g/day for women and men, respectively) in individuals with obesity. This will be performed both as 2 days of very low calorie diet (500 and 600 kcal/day for women and men, respectively) and 2 days of eucaloric low carbohydrate diet.
Currently researches are focusing on the effect of antioxidants in the treatment of non-alcoholic fatty liver disease (NAFLD). Since N-acetyl cysteine (NAC) has been proven to have antioxidant and anti-inflammatory properties, therefore, we will conduct this study to determine the effect of NAC in patients of NAFLD with raised liver enzymes.
The purpose of this study is to evaluate Non-Alcoholic Fatty Liver Disease (NAFLD) and Non-Alcoholic Steatohepatitis (NASH) changes in terms of steatosis and elasticity in patients with morbid obesity 1, 3 and 5 years after bariatric surgery. In addition, genomics, microbiome and metabolomics analyses will be carried out.
Multi-omics approach was used to identify patterns of serological biomarkers to diagnose NAFLD. The purpose of this study is to develop and validate a blood-based assay to diagnose NAFLD by collecting blood sample from healthy patients undergoing routine screening ultrasonography and from patients recently diagnosed with NAFLD.
The global wave of obesity has affected dramatically the incidence of non-alcoholic fatty liver disease (NAFLD) making it the leading cause of liver disease in the western world. NAFLD is considered the hepatic manifestation of metabolic syndrome and is strongly associated with type II diabetes, sleep apnea and cardiovascular disease. Although cardiovascular disease is the leading cause of death in patients with NAFLD, a subset of patients who meet the histological criteria for steatohepatitis have the highest risk for liver-related morbidity and mortality. Reviewing literature, it appears that several pathophysiologic mechanisms related to metabolism, inflammation and fibrosis are deregulated in NAFLD. Choline, Vitamin C, Vitamin E and Ampelopsis Grossedentata natural extracts exhibit high antioxidant activity. In contrast to Vitamin E, which has been extensively studied and has a role as a drug of choice in non-diabetic patients with NAFLD, epidemiological or clinical data for the use of Choline, Vitamin C, Ampelopsis Grossedentata natural extracts or their combination in NAFLD are limited.
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
Significant weight reduction, achieved by low-calorie diet (LCD), will mobilise ectopic fat (visceral and particularly liver fat), improving insulin sensitivity and other metabolic syndrome components, with secondary beneficial effects on cardiac structure and function. This CALIBRATE study (metabolic, multi-organ and effects of low-calorie diet in younger obese patients with pre-diabetes) will compare the effects of a safe and effective 12-month weight management intervention, initially using a low-calorie, liquid replacement diet for 12 weeks, anticipating at least 10% reduction in body weight. The investigators will examine how much the weight loss improves the metabolic abnormalities that precede type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease (CVD). This study will compare the effects of a safe and effective 12-month weight management intervention, initially using a low-calorie, liquid replacement diet for 12 weeks, followed by a weight maintenance phase. The investigators will examine how much the weight loss improves the metabolic and neuropathic abnormalities that precede and accompany type 2 diabetes (T2D), and in reversing the pre-clinical/subtle clinical abnormalities of the liver and heart that precede liver and cardiovascular disease. In an additional optional sub-study, the investigators will additionally assess how the weight loss impacts upon appetite regulation within the brain with functional MRI (fMRI).
Obesity is associated with a variety of co-morbidities. Children with obesity are more likely to have risk factors associated with cardiovascular diseases (CVD) and CVD risk markers (e.g. hypertension, elevated serum cholesterol, and type 2 diabetes mellitus), but also with organ specific pathologies such as a non-alcoholic fatty liver disease (NAFLD). A recent meta-analysis has shown that the prevalence of NAFLD in obese pediatric populations is approximately 35%, compared to approximately 8% in general pediatric population, making it a very important health threat in these populations. Successful pharmacological interventions to treat or prevent NASH are not yet available and so far only weight loss has clear benefits. However, it is well known that sustained weight-loss is difficult to achieve on the longer-term. The investigators recently demonstrated in mice that plant sterol and stanol ester consumption inhibited the development of liver inflammation. Moreover, Javanmardi et al. recently demonstrated in a population of adult NAFLD patients, that plasma concentrations of Alanine Transaminase (ALT) were reduced after daily plant sterol consumption (1.6 g/d) for 6 weeks. In this study, the investigators propose to evaluate the effect of consuming soft chews enriched with plant stanol esters (3 grams/day) on ALT concentrations in children with overweight or (morbid) obesity who are at risk of developing NAFLD, in a randomized, placebo-controlled, double blinded study with an intervention period and follow-up period of 6 months. 52 overweight and obese children with elevated ALT concentrations (>39 U/L for boys and >33 U/L for girls) will be included. All children will be randomly allocated to consume control or plant stanol ester enriched soft chews on a daily basis for a period of 6 months. After 12 months there will be an additional blood sample to evaluate whether the 6 months intervention is still effective.
NAFLD, closely linked to overweight and insulin resistance, has reached 25% prevalence worldwide. Advanced liver fibrosis(ALF) must be accurately diagnosed in NAFLD because it defines a subgroup of patients with impaired prognosis, and these patients need a specific management to prevent the occurrence of liver-related complication. Relatively few NAFLD patients develop ALF and it is a challenge for physicians to identify them. Liver biopsy is the reference for liver fibrosis evaluation but this invasive procedure cannot be first-line used in NAFLD. Non-invasive diagnosis of liver fibrosis is now available, especially liver stiffness measurement (LSM) with Fibroscan and blood fibrosis tests. However, Fibroscan is a costly device available only in few specialized centres with thus poor accessibility in face of the large NAFLD population. Blood fibrosis tests can be performed by every physician and are distinguished as "complex" or "simple". Because they include specialized biomarkers, complex blood fibrosis tests are accurate for the diagnosis of ALF but they are quite expensive and not reimbursed, with therefore limited use in clinical practice. Simple blood fibrosis tests have the advantage to include cheap and easy-to-obtain biomarkers with simple calculation thanks to free websites or smartphone applications. Simple blood fibrosis tests are globally less accurate than complex blood fibrosis tests or Fibroscan but, used with a high-sensitivity cut-off, they have the high interest of being able to accurately rule out advanced fibrosis in a significant proportion of NAFLD patients. Recently, two sequential diagnostic procedures have been developed for the diagnosis of ALF with the idea to combine the advantages of the different kind of fibrosis tests: the FIB4-Fibroscan (FIB4-FS) and the eLIFT-FibroMeterVCTE (eLIFT-FMVCTE) algorithms. These algorithms include as first-line procedure a simple blood fibrosis test (FIB4 or eLIFT) which identifies the patients who require a further second-line evaluation with a more accurate non-invasive test (Fibroscan or FibroMeterVCTE). Liver biopsy is finally used as third-line procedure in patients for whom the diagnosis remains undetermined. Such algorithms have the advantage to limit the use of complex fibrosis tests only to a subset of at risk-patients. The TRAFIC study compare two strategies for the diagnosis of ALF in NAFLD patients: the FIB4-Fibroscan algorithm and the eLIFT-FibroMeterVCTE algorithm
