Alcohol Use Disorder and Alcohol-Associated Liver Disease: New Definitions, Screening, and Treatment

Alcohol-associated liver disease (ALD) poses a significant global health burden and is a leading cause of liver-related morbidity and mortality. ALD encompasses a spectrum of disease states ranging from asymptomatic steatosis to acute hepatitis and cirrhosis. Alcohol use disorder (AUD) significantly increases the risk of developing ALD, and insight into AUD can provide a more complete understanding of ALD and the patients affected by these interrelated diseases. Accurate and timely identification of AUD, even in primary care, through validated screening tools combined with blood tests and imaging techniques facilitates early detection of ALD. Although liver transplantation (LT) remains the most effective treatment for end-stage ALD, patient outcomes post-LT have evolved because of shifting perspectives on ALD transplant eligibility, comprehensive pre-LT evaluations, and advancements in post-LT ALD detection. Nonetheless, addressing disparities in LT practices for ALD is paramount for ensuring equitable access to this life-saving intervention. This article offers an updated synopsis of ALD definitions, screening methodologies, and contemporary management approaches, particularly in the context of LT.
