Filter by:This study is designed to investigate the effect of NASH (non-alcoholic steatohepatitis) on the disposition of 99mTechnetium(Tc)-mebrofenin and to relate changes in 99mTc-mebrofenin disposition to differences in the bile acid profile and Fibroscan Fibrosis Score of healthy subjects compared to patients with NASH.
Nonalcoholic fatty liver disease is one the most commonly encountered conditions in a daily outpatient Hepatology clinic. Secondly our country is the diabetic capital of the world and so the incidence of NAFLD (Non Alcoholic Fatty Liver Disease) is expected to rise in the future. It is a spectrum of hepatic pathology, ranging from simple steatosis, steatohepatitis, to cirrhosis. Nonalcoholic steatohepatitis (NASH) is a more advanced form of disease where steatosis is accompanied by hepatocyte injury as well as infiltration of inflammatory cells. Approximately 10-20% of patients with NASH may progress to cirrhosis. NASH is felt to be a major etiology of cryptogenic cirrhosis. Around 6230 human studies out of which 49 RCTs have been done till date to define the appropriate treatment of nonalcoholic steatohepatitis. However, still a controversy and no recommended treatment available till date. Recently published PIVENS trial has shown that Vitamin E has proven benefit in NASH. Other trials have also shown that pentoxiphylline has shown benefit in the form of histological improvement and biochemical improvement in the form of liver enzymes. Role of SAMe has been studied in alcoholic liver disease and showed to improve in both biochemical and histological features. However the usefulness of SAMe in NAFLD is not known till now. Hence this study has been designed.
Non-alcoholic fatty liver disease (NAFLD) comprises a spectrum ranging from simple fatty liver over steatohepatitis (NASH) to liver cirrhosis and cancer (HCC) and is a major and increasing health problem affecting nearly 40% of the general population. Moreover, NAFLD is an important risk factor for progression of diabetes and atherosclerosis. However, the pathomechanisms determining disease progression are poorly understood. The overall aim of this project is to test the central hypothesis that excessive fructose consumption provides a multiple metabolic hit in the pathogenesis and progression of NAFLD/NASH by impairment of hepatic lipid homeostasis and mitochondrial function resulting in hepatic lipotoxicity with inflammasome activation and disturbed interorgan cross-talk among insulin sensitive tissues.
To study the effects of synbiotics supplement on lipid profile, liver enzymes, inflammatory factors and hepatic fibrosis in patients with Nonalcoholic Steatohepatitis (NASH), 50 patients who referred to Gastrointestinal (GI) clinic with steatosis grade 1 or more will be randomly allocated to receive 2 protexin capsules or placebos for 7 months; both groups will be advised to adherence our diet and exercise program too. At the first and the end of the intervention, lipid profiles, liver enzymes, some inflammatory cytokines, and liver fibrosis will be assessed and compared between groups.
The purpose of the study is to see if the drug ezetimibe is a potential treatment for Nonalcoholic Steatohepatitis(NASH).
The study will determine the feasibility of using Bioenteric intragastric balloon (BIB) in the treatment of patients with Non alcoholic Steatohepatitis (NASH).
The spectrum of NAFLD as emerging epidemic ranges from steatosis to steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC). Disease progression is poorly understood and treatment options are limited. Fructose overconsumption has been associated with gut permeability and progression of NAFLD. To unravel the mechanisms of fructose-induced intestinal changes, volunteers will receive a 4-week fructose challenge prior to assessment of intestinal permeability/translocation using endomicroscopy, sugar probes, serum markers of intestinal damage, inflammation, iron/copper homeostasis and histological/molecular analysis of intestinal biopsies. Findings in volunteers will be compared with liver patients undergoing study procedures without fructose challenge. Translational in vitro experiments will explore cellular responses to fructose and endotoxin. This project should provide novel insights into dietary induced alterations of the gut integrity in progression of NAFLD to NASH.
Abstract: Fatty liver most frequently corresponds to a fat overload of the liver. It is usually classified as alcoholic steatosis or non-alcoholic steatosis. In the case of non alcoholic fatty liver overload, the histological spectrum ranges from simple steatosis to steatohepatitis (NASH) which associates inflammation to steatosis, with a risk of progression to fibrosis and cirrhosis. Obese patients are at particular risk of NASH. Screening of these hepatic lesions is difficult especially as they may exist while the liver tests are normal. The diagnosis of NASH is currently done by liver biopsy, which exposes them in particular to the risk of hemorrhagic complications. Number of subjects required: According to the literature and data collected Louis Mourier in the recent years, the inclusion of 200 patients would examine 20-40 patients with severe histological steatosis and steatohepatitis. All patients will be included in Louis Mourier hospital. Follow-up: one month Search duration: 37 months Duration inclusions: 36 months The total duration of participation for a patient will be one month. Methodology: It is a monocentric, prospective study evaluating the value of noninvasive tests for the diagnosis of hepatic lesions in morbid obese patients. The "open " MRI system allows access to MRI for all obese patients (maximum weight 250 kg). Three of such systems are available in France and liver pathology can be explored only on the system of Louis Mourier. The reference method is liver histology; studied tests are abdominal MRI, Fibroscan / CAP, and serum tests. Examinations required specifically for research Examinations required specifically for the research is abdominal MRI, FibroScan/ CAP and serum tests. Primary endpoint : To validate the use of abdominal MRI, the FibroScan/ CAP and serum tests for finding severe steatosis and / or NASH, specificity, sensitivity, positive and negative predictive values of these tests are calculated. The gold standard is the result of histology on liver biopsy, with a morphometric study of these parameters. ROC curves are used to determine the best compromise between sensitivity and specificity. The secondary endpoints were: Histological lesions of liver fibrosis. Quantification of abdominal fat by MRI (in the form of three variables of interest: quantification of the surface of the visceral fat, of subcutaneous fat and of intrahepatic fat assessed by the percentage loss of signal
The incretin effect is impaired in patients with type 2 diabetes mellitus (T2DM), thus GLP-1 receptor agonists are used for the treatment of T2DM. Insulin resistance is a pathophysiologic hallmark of non-alcoholic fatty liver disease (NAFLD). The incretin effect in patients with NAFLD has not been studied. The aim of this study is to quantify GLP-1 secretion in response to oral glucose tolerance test (oGTT) in patients with NAFLD compared to healthy controls. The results of this study will expand the knowledge of the pathophysiology of NAFLD and serve as a rational for potential future treatment strategies.
The aim of the present study was to compare the effects of simvastatin and L-carnitine coadministration versus simvastatin, L-Carnitine monotherapy on liver transaminases and liver elasticity in NASH patients.
