Active clinical trials for "Liver Diseases, Alcoholic"

Excessive alcohol consumption is a major public health problem, particularly in France. It is the leading cause of cirrhosis and hepatocellular carcinoma. Among subjects with heavy alcohol consumption, the majority of patients develop fatty liver overload (steatosis), but only 10 to 35% develop acute alcoholic hepatitis (AAH) and 8 to 20% progress to cirrhosis. Steatosis is the earliest lesion, rapidly reversible after abstinence from alcohol. On the other hand, the occurrence of AAH leads to a strong progression of fibrosis. The investigators have shown on serial liver biopsies that a subgroup of heavy drinkers develop episodes of AAH and progress to cirrhosis. Therefore, factors other than the amount of alcohol consumed alone influence the development and progression of alcoholic liver disease (ALD). Among these factors, it is now accepted that the gut microbiome plays an important role in the pathogenesis of ALD. Increased intestinal permeability and activation of the innate immune system by lipolysaccharide (LPS) of digestive origin is a key factor in the initiation of AAH. The alteration of the intestinal barrier induced by alcohol abuse seems to involve dysbiosis. Furthermore, the investigatorshave shown that the sensitivity of the liver to alcohol toxicity is transmissible from humans to mice via the gut microbiome. Despite these advances, the causal relationship between mycobiome disruption and ALD in humans requires confirmation in prospective studies. The intestinal microbiome represents all the microorganisms found in the digestive tract: bacteria (bacterial microbiome), viruses (virome), fungi (mycobiome). Recent data point to the role of disturbances of the mycobiome and the virome in human pathology. The intestinal virome consists of two major types of viruses: eukaryotic RNA and DNA viruses that infect host cells and prokaryotic or bacteriophage viruses that infect the bacterial microbiome. Recent evidence suggests that the virome participates in immune system homeostasis. Infection of axenic mice with murine norovirus restores the functionality of intestinal lymphocytes. However, the involvement of the intestinal virome in ALD has never been studied. Cessation of alcohol consumption has a beneficial effect in all stages of ALD . It reduces the risk of complications of cirrhosis and, for early stages of liver damage, prevents progression to advanced stages (severe AAH and cirrhosis). Unfortunately, most patients with alcohol addiction do not achieve long-term abstinence or significant reduction in their consumption despite psychological and medical support. Depression and anxiety are also associated with gut dysbiosis in humans. The causal role, at least partial, of this dysbiosis in addictive phenomena, whether alcohol or other addictions such as cocaine, has been shown. Thus, the modification of MI influences the addictive behavior of cocaine-dependent mice (. All these data show the major role of the microbiota-central nervous system (CNS) axis in mental disorders such as alcohol addiction and its consequences (craving, depression, anxiety). This interaction is mediated by several mechanisms such as the production of active metabolites by the intestinal microbiome and the translocation of bacteria or bacterial derivatives. Primary Objective: To characterize temporal changes in the gut microbiome (bacterial, viral, and fungal) within sequential specimens (stool, saliva, serum) prior to the occurrence of acute alcoholic hepatitis episodes Secondary Objectives: Demonstrate that specific fecal, serum, or saliva microbiome profiles (bacterial, viral, and fungal) can predict the progression of alcoholic liver disease to severe alcoholic hepatitis, fibrosis, and cirrhosis. Characterize changes in the composition of the gut microbiome (bacterial, viral and fungal) associated with the progression of alcoholic liver disease to severe alcoholic hepatitis and cirrhosis. Characterize the changes in the microbiome during alcohol withdrawal. Identify microbiome profiles associated with alcohol dependence and anxiety-depressive events related to alcohol addiction. To identify bacterial species with a protective effect in alcoholic liver disease. To identify beneficial bacterial species against alcohol dependence. To study the microbiome-host interaction in alcoholic liver disease and alcohol addiction. To identify microbiome profiles with prognostic value in severe alcoholic hepatitis and alcoholic cirrhosis. Number of centers: 7 Number of subjects expected 1000 Population concerned: The study will include a population of patients with excessive alcohol consumption seen in consultation or hospitalized for alcohol addiction problems and/or exploration of alcohol-related liver damage Inclusion period: January 2020 - January 2030 Patient observation period: 5 to 20 years Study duration: 30 years

This prospective, analytic observational study will investigate alcohol recidivism in patients with alcoholic liver disease. All adult subjects presenting with alcoholic liver disease are considered for inclusion. Subjects able to give consent are included.

Alcoholic hepatitis carries a risk of high mortality at short term, especially in its severe form. Its diagnosis is confirmed by liver biopsy. The prevalence of alcoholic hepatitis, severe or not severe, is poorly known and prospective data are needed. The present observational study aims to define the prevalence of alcoholic hepatitis among patients admitted for jaundice and determine their outcome according to the severity. Survival and markers of liver dysfunction will be assessed. A biobank including genetic samples will be created to identify the disease profile in terms of inflammation and regeneration. The performance of non-invasive criteria for diagnosis will also be studied.

This is an observational study that will explore the hypothesis that by combining data from patients with liver disease with novel blood biomarkers, single nucleotide polymorphism (SNP) analysis and faecal microbiome analysis. The Investigators will improve diagnosis of liver fibrosis compared to the current available diagnostic tools.

In this study we plan to demonstrate that ethanol induces skeletal muscle autophagy to degrade MAA adducts.

The availability of biological samples from individuals with alcoholic liver disease (ALD), as well as samples from appropriate heavy drinking, yet healthy controls and non-drinking healthy controls, is an essential first step in the translation of basic research advances to the clinic. The purpose of the Clinical Core component of the P50 Northern Ohio Alcohol Center (NOAC) is to provide biological samples (plasma/serum, buffy coats, and urine) from patients with different stages of alcoholic liver disease, as well as healthy control subjects, to members of the NOAC. These samples can then be used to test specific hypotheses related to the presence of specific biomarkers in the serum, functional immune activity in PBMCs and/or genetic polymorphisms that may predict severity of disease, short- and long-term morbidity and mortality and/or responsivity to specific therapeutic interventions commonly used in clinical practice. This study is building on the established biorepositories and the diversity of outstanding clinical expertise at the Cleveland Clinic. This biorepository included clinical samples (plasma, serum, buffy coats, and urine) from patients with different stages of ALD and subjects who are heavy drinkers without ALD, recruited from the Cleveland Clinic alcohol use disorder treatment clinic. This study will be responsible for collecting more data to help build the CCF-ALD biorepository via subject recruitment and communication and specimen collection.

Alcoholic liver disease represents the major health issues and it ranges from simple steatosis to cirrhosis. There is a paucity of data to support the allopathic intervention among these group of patients. Livitol-17 consist of the 3 whole herbs and extract which has antioxidant, hepatoprotective as well as reno-protective properties. The aim of this trial is to study the efficacy of herbal supplement to improve the liver function of alcoholic liver disease subject.

To provide a framework for successful clinical trials testing novel targets for therapy in liver disease. To identify molecular and cellular drivers of liver disease to provide a molecular classification and study the determinants or key drivers of disease progression. Consecutive patients admitted with steatohepatitis (alcoholic or non-alcoholic) will be enrolled in this study where liver tissue, blood and stool will be collected to discover and validate factors associated with diagnosis, severity, histological characteristics, development of decompensations, progression of disease and survival.

The fecal mycobiome, which refers to the community of fungi that resides in the human gut, is an important component of the gut microbiome. Research has shown that changes in the gut microbiome, including alterations in the fecal mycobiome, may play a role in the development and progression of alcoholic liver disease (ALD).One study published in the journal Gut Microbes found that individuals with ALD had a different gut microbiome composition compared to healthy individuals, including alterations in the levels of certain fungal species. Specifically, the study found that there was an increase in the abundance of the fungal genus Saccharomyces in individuals with ALD. This is significant because Saccharomyces is known to produce ethanol, which can contribute to liver damage in individuals with ALD.Another study published in the journal PLOS One found that there were differences in the levels of fungal metabolites in the fecal samples of individuals with ALD compared to healthy individuals. Specifically, the study found that there were higher levels of certain fungal metabolites, including acetaldehyde and ethanol, in the fecal samples of individuals with ALD.These findings suggest that the fecal mycobiome may play an important role in the development and progression of ALD. Maintaining a healthy gut microbiome through a balanced diet and other lifestyle factors may be an important strategy for preventing and managing ALD, and further research into the role of the fecal mycobiome in this condition is warranted.

The current goal in the treatment of Alcoholic Liver Disease (ALD) is to manage ALD-associated complications as there are no disease-specific therapies. Identifying disease-specific therapies to slow ALD progression is critical to improving the outcomes in these patients. Despite preclinical treatment studies in animal models that have shown promise, clinical trials in ALD patients have been limited by the absence of sensitive, quantitative methods for identifying severity and monitoring progression of liver disease. The rates of progression of liver disease in ALD are variable and difficult to predict, which makes assessments of therapies difficult. Clinical measures of hepatic or biliary disease (e.g., bilirubin, transaminases) may be normal, only mildly elevated and/or stable despite ongoing organ damage. Liver biopsies are diagnostic, but are invasive and are of limited value for longitudinal monitoring. Currently clinical imaging, including standard volumetric imaging (MRI and ultrasonography) and hepatic fibrosis assessment (e.g. Fibroscan) are also of limited utility in fully staging disease severity and monitoring progression in ALD. The absence of clinically available methods for accurately determining the severity and progression of liver disease progression in ALD has limited implementation of clinical trials using novel therapeutic agents. Development of non-invasive imaging biomarkers to assess rates of liver progression will overcome this barrier and allow for such studies to be undertaken. This study intends to perform a one-time MRI on patients with ALD to search for these biomarkers that can improve the diagnosis and treatment of ALD patients.
