Alcohol use disorders and liver fibrosis: an update

Alcoholic liver disease (ALD) is currently, worldwide, the second most common cause of human fatalities every year. Alcohol use disorders (AUDs) lead to 80% of hepatotoxic deaths, and about 40% of cases of cirrhosis are alcohol -related. An acceptable daily intake (ADI) of ethanol is hard to establish and studies somewhat controversially recommend a variety of dosages ofADI, whilst others regard any intake as dangerous. Steatohepatitis should be viewed as "the rate limiting step": generally, it can be overcome by abstinence, although in some patients, abstinence has little effect, with the risk of fibrosis, leading in some cases to hepatocellular carcinoma (HCC). Chronic alcoholism can also cause hypercortisolism, specifically pseudo -Cushing Syndrome, whose diagnosis is challenging. If fibrosis is spotted early, patients may be enrolled in detoxification programs to achieve abstinence. Treatment drugs include silybin, metadoxine and adenosyl methionine. Nutrition and the proper use of micronutrients are important, albeit often overlooked in ALD treatment. Other drugs, with promising antifibrotic effects, are now being studied. This review deals with the clinical and pathogenetic aspects of alcohol -related liver fibrosis and suggests possible future strategies to prevent cirrhosis.
