Active clinical trials for "Fatty Liver"

"The goal of this work is to critically test the hypothesis that there exists a different profile of bile acids (BAs) in patient with type 2 diabetes mellitus (T2DM) compared with normal controls. Through confirmation of different profile of BAs in T2DM, investigator will suggest modulation of specific bile acids as a new possible treatment target in patients with T2DM. Investigator also expect the specific BAs signature will be used to screen T2DM before hyperglycemia. In addition, investigator will evaluate the association between each BA species and serum total glucagon like peptide-1 (GLP-1) or fibroblast growth factor-19 (FGF-19) concentrations to determine if the specific BAs profile is related with total GLP-1 or FGF-19 concentration in serum. Investigatr also evaluates the correlation between each BA species and metabolic profiles and oxidative stress marker to find possible roles of each BA component in glucose metabolism.

The aim of this sudy is to investigate the prevalence of colorectal cancer (CRC) in patients with nonalcoholic fatty liver disease (NAFLD) and evaluate whether NAFLD is a risk factor for CRC.

Main objectives 1. Establish the association of psoriasis and the presence of NAFLD in the patients with psoriasis attending dermatologic clinic center. Secondary objective Evaluate for the presence of other components metabolic syndrome in this group of patients including hypercholesterolemia, hypertension, obesity, and insulin resistance Determine if there is an association between the extent and severity of psoriasis and the presence of NAFLD. Identify an association between BMI and presence of NAFLD in people with psoriasis and use it as a predictive index for primary screening of NAFLD in psoriatic patients.

This will be a multi-center, prospective, controlled study. It is expected that about 240 subjects from 10 study centers will be enrolled, and 224 effective subjects will be statistically analyzed in the end, in which 56 effective subjects with stage F0 (25%), 56 effective subjects with stage F1 (25%), 56 effective subjects with stage F2 (25%), 56 effective subjects with stage F3 (25%). By comparison of the result of FibroTouch examination with that of liver biopsy, their specificities, sensitivities and accuracies for diagnosis of liver steatosis will be identified. The patients with liver diseases who need to have a liver biopsy in hospital and meet all of the inclusion criteria and none of the exclusion criteria, may participate in this study. Within two weeks of FibroTouch examination, subjects are required to have qualified histological specimens of liver biopsy for comparation.

Fructose-containing sugars have been implicated in the epidemics of obesity, diabetes and related cardiometabolic disorders. This view is supported by lower quality evidence from ecological observations, animal models, and select human trials. Higher level evidence from controlled trials and prospective cohort studies have been inconclusive. Whether sugars contribute to cardiometabolic complications independent of their calories remains unclear. To address the uncertainties, the investigators propose to conduct a series of systematic reviews and meta-analyses of the totality of the evidence from controlled trials to distinguish the contribution of fructose-containing sugars from that of energy in the development of markers of cardiometabolic risk. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design.

Obesity and obesity related health problems are globally recognized as one of the major threats to public health. Bariatric surgery is the most effective and durable therapy option for obesity and the improvement of obesity related co-morbidities. "Non alcoholic steatohepatitis" (NASH) is an important comorbidity of obesity and improves after surgical intervention. In this study investigators try to enlighten the weight independent mechanism for the effects of bariatric surgery. Patients who are assigned to a bariatric procedure will be observed for at least 24 month. A liver and adipose tissue samples are gained during the operation. Liver function and morphology are observed before and after operation with LiMAx, FibroScan and ultrasound. Systemic inflammation is measured in blood samples before and after surgical intervention. In order to check the microbiome stool samples are collected throughout the entire observation period.

The investigator put forward the hypothesis that liver fat mass in patients with pituitary gland failure is greater than that in a control population. Failure of the anterior pituitary and more particularly impaired production of growth hormone (GH) could be the principal mechanism responsible for increased liver fat mass in these patients.

This is an epidemiologic study on effect of hepatic steatosis on prognosis and outcomes of patients with chronic hepatitis B.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of abnormal liver biochemistry tests in the world. The prevalence rate of NAFLD has been reported to be 30-40% in men and 15-20% in women, up to 70% of people with type 2 diabetes mellitus (Type 2 DM) and even surpassing 74% to 90% of morbidly obese patients with body mass index (BMI) higher than 35 kg/m^2. The primary aims of this prospective cohort study would evaluate the predictive factors of successful weight reduction, NAFLD and nonalcoholic steatohepatitis (NASH) improvement in a large cohort of morbidly obese patients undergoing bariatric surgery. Secondarily, the diagnostic accuracy of noninvasive serum markers, doppler ultrasonography and transient elastography would be validated. Thirdly, we would conduct gene expression analyses to elucidate biological pathways underlying NAFLD phenotypes in this unique cohort.

Obesity is associated with a variety of comorbidities, amongst which non-alcoholic fatty liver disease (NAFLD). A recent meta-analysis has shown that the prevalence of NAFLD in obese pediatric populations is around 35%, compared to approximately 8% in general pediatric populations, making it a very important health threat in these populations. The golden standard for diagnosis of NAFLD is liver biopsy. However, since liver biopsy is associated with a certain risk of morbidity and mortality, this method is inappropriate for screening large populations at-risk for developing NAFLD. Magnetic resonance spectroscopy has demonstrated excellent correlation with liver biopsy and the is the most accuratete non-invasive method to measure liver fat content in children. However, MRS is expensive and not available in all centres. A novel ultrasonographic measurement to quantitatively assess liver steatosis is the hepatorenal index (HRI). Previous studies have shown high sensitivity and specificity of the HRI, as compared to MRS and liver biopsy. However, this measurement has never been validated in children. In this study, the HRI will be compared to MRS in children with obesity, to validate the HRI and to determine cut-off points.
