Filter by:The study is designed as a 12-week randomized controlled dietary intervention in individuals who had been diagnosed with NAFLD in the last 6 months and whose body mass index is above 25 at the time of participation in the pre-screening. The study sample is determined as 150 subjects and randomization will be done by stratification according to PNPLA3 genotype. At baseline, hepatic steatosis and fibrosis will be measured with Fibroscan, body composition will be analyzed, and transaminases and sugar and lipid metabolism indicators will be examined. The study will be conducted in parallel groups, with each group receiving equal amounts and intensity of Mediterranean diet or low-fat diet therapy. At the end of the 12-week intervention, baseline measurements will be repeated and the efficacy of the Mediterranean Diet and Low-fat diet therapies will be compared, as well as the effect of PNPLA3 mutation on intrahepatic response will be analyzed.
The aim of the study is to estimate the effectiveness of two different exercise programs combined with the Mediterranean diet versus diet alone on inflammatory status in subjects aged 18-65 years with obesity (BMI>30) and Non-Alcoholic Fatty Liver Disease (NAFLD) (CAP >248 dB/m).
The recent development of dissolution dynamic nuclear polarization (DNP) technology for hyperpolarized (HP) 13C imaging offers a promising new avenue for non-invasively accessing fundamental metabolic changes associated with the progression of fatty liver disease in vivo. The purpose of this pilot study is to optimize sequence parameters for hyperpolarized 13C acquisition in the human liver and determine which metabolic changes can be seen in humans with simple, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) when compared to healthy volunteers.
Endoscopic bariatric and metabolic therapies (EBMT) are a non-invasive, safe alternative treatment for patients with obesity. Current FDA- approved devices include intragastric balloons (IGB) and suturing devices for endoscopic sleeve gastroplasty (ESG). These gastric interventions work by interfering with how the stomach expands to accept and process a meal, which slows down how fast the stomach empties. ESG, the procedure the investigators are doing in this study, involves endoscopic suturing to reduce the length and width of the stomach so that the patient feels full faster. Semaglutide is a popular medication for weight loss, and has shown significant weight loss with a good safety profile in clinical trials. In this study, the investigators will compare ESG, Semaglutide only, and an ESG + Semaglutide combination, on weight loss for subjects undergoing the procedure with a history of obesity, liver fibrosis and NAFLD. To better understand how these impact obesity and liver fibrosis, the investigators will track weight loss, laboratory values, liver stiffness, and the patients overall liver health. The suturing device used in the ESG procedure and the semaglutide are all approved by the U.S. Food and Drug Administration (FDA) for endoscopic procedures in the upper gastrointestinal tract and medication management of obesity. This is a study that will randomize patients to 1 of 3 different treatment options: ESG only, Semaglutide only or ESG + Semaglutide. The investigators want to see if adding the weight loss medication to the ESG procedure will increase weight loss and how it will impact liver health.
The investigators aim to evaluate patients with NAFLD for early echocardiographic signs of myocardial dysfunction and if there is any correlation between the degree of steatosis or fibrosis and the degree of myocardial dysfunction. This might be an early predictor for anticipating cardiac dysfunction in such cases who are naturally at more increased risk of cardiovascular complications.
Non-alcoholic fatty liver disease (NAFLD) arising from obesity has become a global health concern. Although exercise is a cornerstone approach for managing NAFLD, detailed exercise prescription guidelines are unavailable. According to World Health Organization (WHO) recommendations, 1 minute of vigorous-intensity physical activity can achieve equivalent health benefits to 2 minutes of moderate-intensity physical activity. It is not known whether this relationship is applicable to exercise prescribed as an adjunct therapy in NAFLD treatment. The answer has public health implications because people living with NAFLD can potentially opt for safe higher-intensity exercise requiring less of a time commitment, whereas those in older age groups or with comorbidities, for whom vigorous exercise is unsuitable, can adopt a moderate-intensity regimen of longer duration to acquire equivalent therapeutic outcomes. Adults with obesity and NAFLD will be randomly allocated to a supervised vigorous- or moderate-intensity walking group or usual care control group. Each exercise group will receive a 16-week intervention comprising three walking sessions weekly, whereas the usual care group will receive general health education as the attention control. The per-session walking time will be 25 minutes for the vigorous group and 50 minutes for the moderate group, equating to the same weekly exercise volume and caloric expenditure for each group according to the WHO's minimum physical activity recommendation. Outcome measures, including liver fat, visceral and body fat, body anthropometry, intervention adherence, psychological measures, health-related quality of life, medication usage, adverse events, habitual physical activity, and diet, will be examined by assessors blinded to the group allocation at baseline, 16 weeks (post-intervention), and 42 weeks (26-week post-intervention follow-up). Data will be analyzed by generalized estimating equations and linear contrasts. The proposed study will provide evidence on the presumed equivalent benefits of vigorous- and moderate-intensity exercise, with a follow-up period allowing assessment of the efficacy, safety, adherence, and sustainability of each. The findings will inform practitioners of the role of exercise intensity in reducing liver fat and refine the exercise guidelines for NAFLD patients.
The researchers want to learn how androgens, a type of sex hormone, might affect nonalcoholic fatty liver (NAFLD) in young women over time. NAFLD happens when fat builds up in the liver which can cause damage to the liver such as inflammation or scarring. Young women with a condition called polycystic ovary syndrome (PCOS) have a high risk for NAFLD, and they often have high androgen levels too. So the researchers are recruiting young women with PCOS as well as those without PCOS, and will compare changes in NAFLD over time between young women with and without PCOS. This study is funded by the National Institutes of Health
Liver stiffness is a marker for scarring of the liver, which occurs after damage from various liver conditions. Scarring prevents normal liver function and can lead to liver failure. Fatty liver is a common cause of liver damage and can contribute to scarring. Currently, liver biopsy serves as the 'gold standard' for assessing the degree of liver scarring and fatty infiltration, guiding treatment decisions. However, liver biopsy poses a significant risk of death and unpleasant side effects, including internal bleeding and pain. Moreover, due to the small sample of liver tissue obtained during the biopsy, the results can be misleading and may not provide an accurate overview of the liver's health. Therefore, there is an unmet need for a non-invasive method of measuring liver stiffness and fat content. Ultrasound-based methods utilize various properties of ultrasound waves to assess liver stiffness and fat levels. This study aims to recruit 100-120 patients with chronic liver disease. The investigators will assess liver stiffness and fat levels during patients' hospital visits for routine scans, biopsies, or clinic appointments. The resulting measurements of liver stiffness and fat obtained through ultrasound-based methods will be compared to patients' routine liver biopsies, routine FibroScan results (another non-invasive method routinely used in clinical care to assess patients' liver stiffness), and other non-invasive severity scores (calculated from results obtained from patients' routine blood tests, providing an overview of the extent of liver damage).
In this research, the investigators tested the effect of 12-week supplementation with soy isoflavones on non alcoholic fatty liver disease (NAFLD) management and the level of fibroblast growth factor-21 (FGF-21) and fetuin A as markers of NAFLD progression.
Fibrosis is considered the leading cause of liver diseases and related mortality. Specifically, hepatic fibrosis is regarded as the consequence of reparative mechanisms initiated by hepatocytes in response to chronic damage. In Western countries, the main known etiologies include hepatitis (B and C), alcoholism, and non-alcoholic steatohepatitis (NASH). In particular, obesity is a determining factor in the onset and development of NASH. Alarming statistical data indicate that over 30% of the world's population is obese, and this eating disorder is increasingly affecting young people. NASH is a chronic disease that can present different degrees of fibrosis and, as the final stage, lead to the development of liver cirrhosis. Currently, the only accurate diagnostic and assessment system for this condition is liver biopsy, as there are no accurate non-invasive clinical tests available. The aim of this project is to identify (in silico) potential biomarkers involved in the development and progression of hepatic fibrosis and validate their presence and quantity in serum or plasma samples from obese patients (at-risk population). This would avoid the need for a liver biopsy and allow "at-risk" patients to undergo a simple ambulatory blood draw. Additionally, performing elastometry of the liver would allow for comparison of radiological results with laboratory findings.
