The rational to conduct the LOVE study builds on the lack of available data on outcomes in steatotic liver disease in well characterized patients over a time frame of several years. At current limited data on liver-specific and overall outcome in patients with MASLD, MetALD and ALD are available. Liver histology is the only accepted surrogate to reasonably likely predict outcomes in patients with non-cirrhotic liver disease and is currently used in regulatory trials. To overcome the limitations of liver biopsy and use validated non-invasive tests (NITs) to predict outcomes, the LOVE study will be conducted based on existing cohort studies in well pheno- and genotyped patients and will inform on the relevant outcomes based on baseline and ongoing biomarker assessment. The overarching goal is to qualify a NIT for patient identification and preventive measures in the regulatory context.

Background: Significant sex differences exist in regard to alcohol use disorder (AUD) and alcoholic liver disease (ALD). To date, no studies have examined the brain-gut-microbiome (BGM) axis (which is the relationship between the gut, brain, and the bacteria within the gut) and sex-differences in AUD and ALD. Aims: 1) Demonstrate baseline sex differences in the microbiome and metatranscriptome of AUD and ALD and correlate those differences to severity, 2) determine if these baseline sex differences predicts abstinence or ALD related outcomes, and 3) show how altering the microbiome can decrease the severity of AUD and ALD in a sexdependent manner. Hypothesis: Our project is aimed to explore the hypothesis that sex-related differences of the BGM axis in AUD and ALD explains the variation in patient severity and outcome by sex, and that alterations of the BGM axis can decrease the severity of AUD and ALD in a sex-dependent manner. Methods: A pilot randomized placebo (VSL#3 vs placebo) control trial will be performed in patients with AUD and ALD for 6 months. Questionnaire data, clinical labs, serum, and feces for shotgun metagenomics will be collected at baseline, 3-months, and 6-months. Anticipated Results: Patients with severe AUD/ALD will have more microbes and microbial genes associated with inflammation. These differences will predict outcomes at 6-months and that changes of this baseline microbiome with VSL#3 will lead to more positive outcomes than placebo, with men having greater benefit from VSL#3 than women. Implications and Future Studies: The discovery of the mechanisms underlying sex-related differences in AUD/ALD is needed for the development of personalized recommendations for prevention and treatment in men and women

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
NCT03508388
Investigator seek to determine whether the volume of the liver can predict the survival after a decompensation of a patient suffering from chronic liver disease caused by excessive alcohol consumption (or alcoholic cirrhosis). Our hypothesis is that patients with a "small" liver have a lower survival compared to patients having a "normal" sized liver.

NCT02140294
Patient found to be malnourished after the nutritional evaluation would be randomized in the two groups of the study. The control group would receive standard nutritional counseling from a trained dietician where as those in the intervention group would be given 120 gm of a polymeric nutritional supplement providing around 500 Kcal per day over and above the standard nutritional counseling from a trained dietician. Both the groups would receive standard medical treatment. The polymeric nutrient supplement would be taken by the patients in this arm for a period of 6 months.
NCT02200029
A research study of an approved drug called Heptral®, ademetionine, to treat adults with intrahepatic cholestasis (a condition where bile cannot flow from the liver to the duodenum) in pre-cirrhotic and cirrhotic states. Experience from clinical studies in subjects with liver disease has shown that ademetionine is effective.
NCT00708617
Apart from Fibrotest, non-invasive markers have been validated only for chronic hepatitis C. However as for chronic C hepatitis, non invasive tests (Fibrotest and transient elastometry) are already used in current practice. The aim of this study is to validate the diagnostic value of FIBROSCAN by comparison with liver histology. FIBROSCAN will be also compared to Fibrotest and FIBROSCAN-Fibrotest association to each test alone in order to optimize this diagnostic strategy. Studied variables will be significant fibrosis (≥ 2 in the METAVIR score) and presence of cirrhosis (score : F4). Diagnostic values of the scores will be expressed by sensitivity, specificity, positive and negative predictive values, and ROC curves. Areas under ROC curve of the scores will be compared using Z test.
NCT00770198
Chronic liver disease are characterized by increased levels of plasma IL-6, but the bioactivity of this cytokine in this disease is not well known. IL-6 receptor complex is regulated by multiple receptors subunits: the soluble form of IL-6 Receptor enhance IL-6 signal by a process called trans-signaling on cells expressing few membrane IL-6 receptors. Soluble gp130 is the natural inhibitor of IL-6 trans-signaling. The aim of this study is to characterize circulating and liver levels of theses compounds of IL-6 receptor complex, to unravel the bioactivity of IL-6 in this disease.
