Filter by:Background: - Non-alcoholic fatty liver disease (NAFLD) is a common cause of abnormal liver tests. It is closely linked to health problems like obesity and diabetes. Researchers want to use a breath test to measure the metabolism of fatty acids and learn more about the causes of disease. They will compare the results between people who do and do not have NAFLD. They will also repeat the test in people with NAFLD after treatment to see improvement. Objectives: - To measure the metabolism of fatty acids and compare them between people who do and do not have NAFLD, and people with NAFLD before and after treatment. Eligibility: - People age 21 and older with NAFLD - Healthy volunteers - non-NAFLD metabolic syndrome Design: - Participants will be screened with medical history, physical exam, and fasting blood tests. - Participants will fast overnight. - Participants will sit in a comfortable chair. They will relax for 15 minutes. Then a narrow plastic tube will be put under their nostrils. It will be connected to a breath test device. - Participants will drink palmitate or acetate in a heated liquid meal (Ensure). Palmitate is a fatty acid and acetate is a small molecule that is a building block for fatty acids. Both palmitate and acetate are natural compounds that are in our body and our food. - Participants will sit for 6 hours. They can read, watch television, work on a computer, or other relaxed activity. The air they breathe out from their nose will be collected and analyzed. They may take a bathroom break after 3 hours. They may drink water after 3 hours. - Participants will get a meal after the test. - Participants will have another visit at least 1 week later. They will repeat the test with the other compound (acetate of palmitate). - Participants may be asked to repeat a test to study the result of a change like weight loss or medicine. Thus, participation can last from 1 week to several years.
Concurrent 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.
This study is a double-blind randomized, placebo-controlled, parallel-group, 12 week study performed in 2 centres in Sweden to assess the effect of Omega-3 carboxylic acids and fenofibrate on liver fat measured with magnetic resonance imaging (MRI) in patients with over-weight and hypertriglyceridemia.
The purpose of this study is to determine whether introducing almonds into the diet of overweight and obese Blacks and Hispanics improves body composition, decreases liver fat, and lowers cardiovascular disease profile.
The purpose of this study is to examine whether non-alcoholic fatty liver disease (NAFLD) is associated with hepatic glucagon resistance and hyperglucagonemia.
A Phase 2a, randomized, double-blind, placebo-controlled, multi-center study of cenicriviroc (CVC) to be conducted in approximately 50 adult obese subjects [body mass index (BMI) ≥ 30 kg/m^2] with prediabetes or type 2 diabetes mellitus and suspected NALFD.
This study investigates the effects of pregnane X receptor (PXR) activation on hepatic fat content in healthy volunteers. Rifampicin (an antibiotic and also an efficient PXR activator) and placebo will be given for a week to volunteers. Hepatic fat content is measured with magnetic resonance imaging and blood samples are collected at the end of each study arm. The investigators' hypothesis is that rifampicin causes accumulation of fat to the liver.
This study will evaluate the safety and preliminary efficacy of two dose levels of IMM-124E in reducing liver fat and/or serum alanine aminotransaminase (ALT) compared with placebo.
This study's aim is to develop an algorithm for the ¹³C-Octanoate Breath Test with or without the ¹³C-Methacetin Breath Test (OBT and MBT respectively) for correlation with histological findings associated with of Non-Alcoholic Steatohepatitis (NASH) and other liver diseases using the BreathID® System
The purpose of this study is to evaluate whether exenatide is superior to insulin glargine (after 24 weeks) in reducing liver fat content (by MRS) in patients with newly diagnosed type 2 diabetes mellitus and concomitant non-alcoholic fatty-liver disease(NAFLD).
