Intra-Individual Reproducibility of the Non-Invasive Assessment of the Portal Circulation
Hepatitis CChronic1 moreHepQuant tests are new liver tests that are being developed to accurately measure liver function with sensitivity and specificity while being safe and non-invasive. The primary goal of this study is to define the intra-individual reproducibility of the HepQuant tests, that is, to see if a person is given the tests several times that the test results are essentially the same each time. Subjects for this study will include healthy controls and patients with chronic liver diseases. The chronic liver diseases will include hepatitis C virus (HCV) infection and a serious form of fatty liver disease, known as non-alcoholic steatohepatitis (NASH). The HCV and NASH patients will include men and women, and those with early stage and late stage liver disease as defined by the amount of fibrosis observed in their liver biopsies. Once a subject has been enrolled in the study they will be given the HepQuant tests on three separate days within the span of one month. The hypothesis of this study is that HepQuant tests will reproducibly report liver function in healthy controls and patients with all stages of chronic HCV and NASH liver disease and that liver function will decrease as the amount of liver fibrosis increases in the chronic liver disease patients.
Placebo Controlled Study Using Lovaza as Treatment for Non-Alcoholic Fatty Liver Disease
Non-Alcoholic Fatty Liver DiseaseLovaza is the only fish oil supplement approved by the FDA. It is available by prescription for the treatment of hypertriglyceridemia (> 500 mg/dl). The primary mechanism appears to be a reduction in hepatic production of triglycerides. Also decreases the hepatic production of very low density lipoprotein (VLDL). There also may be antioxidant properties as well. The thought behind using Lovaza as a treatment for non-alcoholic fatty liver disease (NAFLD) is two fold. It would help in the decrease production of triglycerides by the liver and have antioxidant properties decreasing the production of free radicals in the liver. In doing so, steatohepatitis, fibrosis, and perhaps cirrhosis and liver cancer would be prevented.
Impact of Short-term Fructose-enriched Diet on Serum Metabolome by Normal- and Over-weighed Women....
Non-Alcoholic Fatty Liver DiseaseObesityThe purpose of this study is to investigate how a high-fructose diet, either by high fructose intake from complex, natural foods or by fortifying the diet with corn syrup, affects the metabolism. Furthermore, it will be investigate if there are differences between obese and normal weight participants.
High Fructose Corn Syrup
Nonalcoholic Fatty Liver DiseaseObesityThe purpose of this research study is to learn more about how high fructose corn syrup, a sugar used to sweeten drinks and foods, affects metabolism in obese persons with and without nonalcoholic fatty liver disease. Eligible participants will be studied before and after eating a diet high in high fructose corn syrup or a standard diet (low in high fructose corn syrup) for four weeks.
Ultrasound-Based Liver Fat Quantification (LFQ) Pilot Study
Non-Alcoholic Fatty Liver DiseaseNon-Alcoholic SteatohepatitisThis clinical study will involve performing a series of medical imaging procedures of the abdomen using both ultrasound and MRI modalities in subjects at risk for or already diagnosed with Nonalcoholic Fatty Liver Disease (NAFLD). The primary objective of this clinical study is to evaluate the clinical feasibility of an investigational ultrasound technique for quantifying liver fat by comparing specific ultrasound-derived biomarkers with the liver fat percentage obtained from MRI Proton Density Fat Fraction (MRI-PDFF) measurements. All subjects enrolled in this study will undergo two investigational abdominal ultrasound examinations using the Philips EPIQ Ultrasound System and one MRI PDFF examination according to the clinical standard of care.
Quantitative US for Evaluation of Hepatic Steatosis in NAFLD
Fatty LiverFatty Liver1 moreThe purpose of this study is to evaluate diagnostic performance of quantitative ultrasonographic parameters for the assessment of hepatic steatosis with find optimal cut-off values in patients with non-alcoholic fatty liver disease using magnetic resonance imaging proton density fat fraction (MRI-PDFF) and MR spectroscopy as the reference standard.
Noninvasive Biomarkers of Metabolic Liver Disease 1.1
Nonalcoholic SteatohepatitisNonalcoholic Fatty LiverNIMBLE is a comprehensive collaborative effort to standardize, compare, validate, and advance the regulatory qualification of imaging and circulating biomarkers to diagnose and stage nonalcoholic steatohepatitis (NASH), and to predict and assess response to therapeutic intervention (https://fnih.org/what-we-do/biomarkers-consortium/programs/nimble). This study focuses on estimating the repeatability and reproducibility of ultrasound elastography-based biomarkers across a range of fibrosis stages.
Impact of nCPAP Treatment on Liver Function in Patients With Sleep Apnea Syndrome and Nonalcoholic...
Sleep Apnea SyndromeNonalcoholic SteatohepatitisThis study aims to evaluate the impact of nasal continuous positive airway pressure (nCPAP) treatment on liver enzymes in patients with sleep apnea syndrome and nonalcoholic steatohepatitis. Using a cross over design, the evolution of liver enzymes will be evaluated in 40 patients during a consecutive period of 6 weeks, with and without nCPAP treatment.
