简要总结
Alcohol-associated liver disease is one of the most prevalent liver diseases worldwide, and the leading cause of liver transplantation in the U.S. Alcohol-related liver disease is associated with changes in the intestinal microbiota and metabolites.
详细描述
Backgrounds:
Alcohol-associated liver disease (ALD) is a common disease caused by alcohol use disorder (AUD), ranging from asymptomatic liver steatosis to alcohol-associated hepatitis (AH), alcoholic cirrhosis and potentially, hepatocellular carcinoma (HCC). ALD is the most common reason for liver transplantation in the United States. Globally, about 2 million people die from liver disease each year and up to 50% of the death with cirrhosis can be attributed to alcohol consumption. In Europe, it has been estimated that 60%-80% of liver-related deaths can be attributed to alcohol consumption. Currently, the pathogenetic mechanisms have not been fully elucidated, but they might be related to oxidative stress, acetaldehyde-induced toxicity, cytokine and chemokine-induced inflammation. There is no effective therapeutic method for ALD till now except for liver transplantation. Recent studies have reported that gut microbiota has an intimate relationship with ALD, which provides broader insights and opportunities for understanding and treating this disease.
Aims:
We aim to map the alterations of gut microbiota and metabolites in patients with different levels of ALD, and to investigate the effects and mechanisms of key strains and their metabolites on the development of ALD, providing a theoretical basis and potential targets for its treatment.
