Active clinical trials for "Liver Diseases"

The purpose of the study is to determine whether LY3314814 can be safely prescribed in participants with liver impairment without a dose adjustment. Participants will be on study for 11 days with follow-up about 7 days afterward.

This study will demonstrate Short-, mid-, and long-term safety in pediatric patients with Parenteral Nutrition-Associated Cholestasis treated with Omegaven®, which is indicated as a source of calories and fatty acids in this patient population

Liver cancer is one of the leading causes of cancer death among Asian men. If diagnosed early the disease is treatable with surgery. Current conventional imaging modalities have limitations to early detection. This study proposes to use 18F-FGal and 18F-FDG PET/CT scans to compare the clinical efficacy of diagnosing hepatocellular carcinoma (a type of liver cancer) using these PET/CT scans.

This observational registry of patients undergoing liver surgery collects patients both retrospectively and prospectively. Patients undergoing liver resection for any non-transplant indication will be evaluated for clinical outcomes (such as surgical complications, survival, and disease progression) based on clinical and patient factors (like indication, age, and other treatments for the disease).

In order to persist in the liver, HCV has numerous nonspecific and specific strategies to overcome the immunity of the host. The crucial step in the establishment of viral persistence and chronic hepatitis is the avoidance of specific antiviral cellular immune response in the liver. Treatment with pegylated interferon alpha (IFNα) in combination with ribavirin (RBV) is the standard therapy for chronic hepatitis C is. The response to IFNα / RBV therapy depends on the effective cellular antiviral immune response in the liver. The understanding of the interaction between HCV and cellular immune response is important for the effective use of existing diagnostic techniques, the Individual control and adjustment of the current therapeutic approaches and the development of future therapeutic and immunization strategies. In this study, the investigators want to investigate cellular Immune responses in the liver of HCV infected patients and characterize the influence of these immune responses to the response to IFNα / RBV therapy.

The prevalence of non-alcoholic fatty liver disease (NAFLD ) in the American population is approximately 30% in adults and 10% in children, making it the most common. Cause of chronic liver disease in the United States. Although the majority of patients with NAFLD have a benign clinical course, the development of non-alcoholic steatohepatitis (NASH ), with necro-inflammation and progressive fibrosis, increases the risk for development of cirrhosis and its complications. Among patients with NASH, approximately 28% develop cirrhosis over an 8-year follow-up period. NASH and advanced fibrosis is associated with increased morbidity and mortality among those patients with advanced histologic severity such as NASH and fibrosis the gold standard for diagnosing and staging NAFLD is liver biopsy. Liver biopsy is associated with costs and risks that make it impractical for generalized use in a condition that affects such a high portion of the population. Furthermore, liver biopsy is also limited by significant sampling error in NAFLD. Thus, there is a pressing need for accurate non-invasive predictors of NAFLD that would also allow differentiation of those subjects at higher risk of disease progression. At present, in the clinical setting, some demographic factors, blood tests, and imaging studies can be used to predict a higher risk of disease in patients being evaluated for NAFLD. These predictors, however, are of limited sensitivity and specificity compared with liver biopsy. The development and validation of accurate predictors and scoring systems to identify patients at higher risk for NASH and fibrosis would allow identification of subjects who would benefit the most from liver biopsy and potentially help monitor disease

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the resulting coronavirus disease 2019 (COVID-19) have afflicted tens of millions of people in a worldwide pandemic. Considering its high mortality and rapid spread, an effective vaccine is urgently needed to control this pandemic. Recently, mass vaccination campaigns using newly approved vaccines, ranging from conventional viral and protein-based vaccines to those that are more cutting edge, including DNA- and mRNA-based vaccines are beginning in many parts of the world. Randomized clinical trials of different vaccines reported efficacies for preventing COVID-19 in the range of 50% to 95%. Although these randomized clinical trials are considered the "gold standard" for evaluating intervention effects, they have notable limitations of sample size and subgroup analysis, restrictive inclusion criteria, and a highly controlled setting that may not be replicated in a mass vaccine rollout. The aim of this study is to evaluate the safety, tolerability, immunogenicity, and efficacy of different vaccines against COVID-19 under real-world practice conditions.

Few studies have evaluated an extensive list of possible risk factors for NAFLD for their association with presence and severity of histologic features. We wish to conduct a retrospective study on these possible factors (including demographics, comorbid diseases, and medications) for their association, if any, with severity of histopathologic findings. This study hypothesize that certain risk factors, specifically those contributing to or consisting of metabolic syndrome, will have higher NASH Fibrosis stages.

Chronic liver diseases are common and the two main causes in France are NAFLD (No Alcoholic Fatty Liver Disease Nonalcoholic) and ALD (alcoholic liver disease). Because of the importance of the current global obesity, NAFLD has become very common and it is estimated that its prevalence in the general population reaches 20-30%. NAFLD (No Alcoholic Fatty Liver Disease Nonalcoholic) and ALD (alcoholic liver disease) includes a broad spectrum of liver damage, ranging from simple steatosis isolated (infiltration of fat in the liver), in hepatic inflammation, fibrosis (abnormally high accumulation of extracellular components in the functional liver tissue) and finally cirrhosis and its complications. Choline deficiency (essential nutrient generally classified as Class B vitamins) has been associated with liver damage each characterizing NAFLD and ALD. The amount of choline in the body depends in particular on food intake and degradation of choline by the intestinal microbiota. NAFLD and ALD are complex pathologies resulting from the interaction of environmental / nutritional factors and a genetic background. It therefore appears now necessary to study the influence of the relationship between genetic predisposition, environmental factors, and gut microbiota metabolism of choline on the severity of liver injury observed in NAFLD and ALD. If the interaction of these three elements (the host genetics - environmental factors - and intestinal microbiota metabolic choline) has an influence on the severity of the lesions of NAFLD and ALD direct application may be of bring a food supplement choline in patients at risk (mutation of the PEMT gene (phosphatidylethanolamine N-methyltransferase), postmenopausal women, microbiota profile for increased degradation of dietary choline) to restore the amount of choline in the body and thus to avoid a worsening of the ALD or NAFLD and progression to cirrhosis.

The main objective is to compare the accuracy of transient elastography taking into account liver steatosis determined by MRI, to liver biopsy for the diagnosis of liver fibrosis ≥F2 in patient with NAFLD.
