Non-alcoholic Fatty Liver Disease and Its Treatment
NAFLDDipeptidyl peptidase-4 inhibitors (DPP-4I), key regulators of the actions of incretin hormones, exert anti-hyperglycemic effects in type 2 diabetes mellitus (T2DM) patients. A major unanswered question concerns the potential ability of DPP-4I to improve intrahepatic lipid (IHL) content in nonalcoholic fatty liver disease (NAFLD) patients. The aim of this study was to evaluate the effects of sitagliptin on IHL in NAFLD patients.
Quantitative US for Evaluation of Hepatic Steatosis in MAFLD With UDFF
Fatty Liver DiseaseNonalcoholicUltrasound Derived Fat Fraction (UDFF) Evaluation of Metabolic Related Fatty Liver Disease (MAFLD) in obesity Patients Metabolic fatty liver disease (MAFLD), formerly known as Nonalcoholic Fatty Liver Disease (NAFLD), is the most common chronic liver disease in the world at present, with a incidence rate of about 30%. In the United States, NAFLD is the third leading cause of hepatocellular carcinoma, and early assessment and diagnosis of liver steatosis characteristics are crucial for timely treatment or intervention to reduce the risk of liver fibrosis and inhibit disease progression. Liver biopsy is considered as the "gold standard" for evaluating, grading, and determining inflammatory activity of liver steatosis and fibrosis. However, liver biopsy are invasive and pathological evaluation differences among observers, which makes it difficult to widely use and repeat, especially for dynamic evaluation of patients during the treatment process. Ultrasound Derviced Fat Fraction (UDFF) is a unique technology for non-invasive quantification of liver fat content, which is equipped on the Siemens ACUSON Sequoia ultrasound system. UDFF is calculated from two parameter values: attenuation coefficient (AC) and backscatter coefficient (BSC). SWE (shear wave elastography) is becoming widely used, and is recommended for the evaluation of liver fibrosis by some guidelines in patients with chronic liver diseases, such as viral hepatitis. These two technologies (UDFF+SWE) can be achieved on the same probe, and this detection technology is non-invasive, painless, simple, and reliable. Bariatric surgery (BS), also known as metabolic weight loss surgery, is currently recognized as the most significant and long-lasting method for treating obesity. It can significantly improve obesity related comorbidities, as well as long-term improvement in postoperative quality of life and mental state. This study will aim on analysis of the liver ultrasound characteristics of patients who plan to undergo bariatric surgery. By using UDFF and elastic shear wave technology (UDFF+SWE), a new non-invasive ultrasound evaluation method for MAFLD grading diagnosis of simple fatty liver, fatty hepatitis, liver fibrosis, and related cirrhosis will be proposed, and the incidence and risk factors of MAFLD in overweight and obese patients will be explored, The reversal effect of weight loss therapy on MAFLD in obese patients.

Omics-based Predictors of NAFLD/Potential NASH
Non-Alcoholic Fatty Liver DiseaseNon Alcoholic SteatohepatitisThe cascade of care for the non-alcoholic fatty liver disease (NAFLD) and its progression to non-alcoholic steatohepatitis (NASH) requires crossing the barriers for their diagnosis and treatment. The multifactorial nature of NAFLD/NASH limits their diagnosis by a single factor solely. This project aimed at developing a powerful composite marker panel based on multi-omics technologies to detect NAFLD without or with fibrosis (potential for NASH) in high-risk populations (obesity, type 2 diabetes, hypertensive, dyslipidemia). This project is an exploratory study to unrevealing the intra-heterogeneity and inter-similarities of NAFLD without and with fibrosis versus those of healthy individuals. The molecular and clinical characteristics of 450 participants (225 adults aged 30-60 years and 225 children aged 12 -18 years) will be investigated; 150 NAFLD patients without, 150 NAFLD patients with fibrosis (potential NASH) compared to 150 healthy individuals. Detection of genetic polymorphism of SNP of 10 gene variants involved with NAFLD without and with fibrosis, gene discovery and molecular diagnosis of dyslipidemia using next-generation sequencing and whole-exome sequencing (genomics), the expression level for the top 5 of 168-panel genes of plasma miRNAs (epi-genomics), the glycosylation pattern of five glycoproteins (proteomics), salivary analysis of ten microbiomes and five microbial-related metabolites (metabolomics) will be investigated. Eventually, the development of precision therapies to target NAFLD without and with fibrosis and possibly reverse fibrosis could be achieved.

Effects of Pitavastatin on Insulin Sensitivity and Liver Fat
ObesityFatty Liver1 moreHMG co-A reductase inhibitors, commonly called statins, are an effective treatment for dyslipidemia and atherosclerotic heart disease with proven mortality benefit. While the lipid-lowering effects of statins are well-known, other metabolic effects, including effects on glucose tolerance and ectopic fat distribution, are less completely understood. Recent studies have shown that some statins may increase the risk of diabetes. Further, research has suggested that statins may have some benefit in nonalcoholic fatty liver disease (NAFLD), a condition associated with obesity that includes increased fat in the liver (steatosis) and, in some cases, inflammation and hepatocellular damage (steatohepatitis). Pitavastatin, approved by the United States Food and Drug Administration (FDA) in 2009, is the most recent statin to enter the market. Unlike most statins, pitavastatin is not primarily metabolized through cytochrome P450 (CYP450), and thus has reduced potential for interactions with other medications that are metabolized by CYP450. Previous studies have suggested that pitavastatin may be neutral to glucose homeostasis and may improve hepatic lipid. Neither of these effects has been proven definitively, however, and the current proposal aims to characterize in detail the effects of pitavastatin on glucose homeostasis, hepatic steatosis, and steatohepatitis.

Low Carbohydrate Diet: The Effects on Non Alcoholic Fatty Liver Disease in Obese Teens With Metabolic...
NAFLDFatty Liver2 moreConcurrent with the rising prevalence of childhood obesity, the co-morbid condition of non-alcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease among children. NAFLD is characterized by accrual of excess triglycerides (TG) in the liver that leads to inflammation, fibrosis, and cirrhosis. One-third of the pediatric population has NAFLD, a disease strongly associated with insulin-resistance and metabolic-syndrome (Met-S). NAFLD is predicted to become the leading cause of liver transplantation in adults by 2030. Current understanding of NAFLD indicates that presence of excess TG in liver is an absolute requirement for disease progression. First-line therapy for NAFLD is focused on decreasing adiposity and improving insulin sensitivity through diet and exercise. Recent adult data indicate that dietary carbohydrate-restriction is more effective at reducing hepatic TG-content than traditional calorie-restriction. Few studies have been conducted to establish resolution of hepatic steatosis by any intervention. Such studies in pediatrics are primarily limited by a need for liver biopsy. However, hepatic proton magnetic resonance spectroscopy (H-MRS) is a new innovative tool used to quantitatively measure hepatic TG content in a non-invasive manner. The primary aim is to compare the impact of dietary weight loss via carbohydrate-restriction and calorie-restriction on hepatic TG-content quantified by H-MRS in obese children with biopsy-proven NAFLD and Met-S. This IRB approved protocol is a randomized control study. The investigators will recruit subjects from the Center for Obesity and its Consequences in Health and the pediatric gastroenterology clinics between the ages of 11-17 years who meet criteria for NAFLD and Met-S. A H-MRS will be obtained in each subject prior to the start of dietary intervention. Fifty-four subjects will be randomized to either a carbohydrate-restricted or calorie-restricted diet for 6 months with no change in baseline activity. A repeat H-MRS will be compared to baseline to determine the whether dietary carbohydrate-restriction is superior to calorie-restriction for reducing hepatic TG content. The investigators believe that subjects on the carbohydrate-restricted diet will have marked decrease in hepatic TG content compared to those in the calorie-restricted diet given the same degree of reduction in body mass index.
