French National MICMAF Cohort

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 intestina…
