Alcohol-associated liver disease - a current overview

Area of Science:

• Hepatology
• Gastroenterology
• Internal Medicine

Background:

• Alcohol-associated liver disease (ALD) is a significant and escalating global health concern.
• Excessive alcohol consumption is a primary preventable cause of liver damage, encompassing a range of conditions with distinct challenges.
• ALD pathogenesis involves complex interactions of oxidative stress, inflammation, lipid metabolism, and genetic factors.

Purpose of the Study:

• To review the current understanding of alcohol-associated liver disease (ALD) pathogenesis, clinical spectrum, and management strategies.
• To highlight the increasing epidemiological burden of ALD, particularly in younger demographics.
• To emphasize the urgent need for novel therapeutic approaches and comprehensive patient management.

Main Methods:

• Literature review of ALD pathogenesis, clinical progression, and treatment modalities.
• Analysis of epidemiological trends and risk factors associated with increased alcohol consumption.
• Evaluation of current management strategies, including abstinence, nutritional support, and liver transplantation.

Main Results:

• ALD progresses from fatty liver (steatosis) to alcoholic hepatitis and potentially irreversible liver cirrhosis, associated with high mortality.
• Strict alcohol abstinence is crucial for halting disease progression and can lead to reversal in early stages.
• Current treatments are limited, especially for advanced ALD, and liver transplantation eligibility is challenging for many patients.

Conclusions:

• Effective management of ALD requires strict alcohol abstinence, nutritional support, and symptomatic treatment.
• There is a critical need for developing innovative therapies and enhancing epidemiological research to combat the rising burden of ALD.
• Individualized patient care and improved access to liver transplantation are essential for improving outcomes in alcohol-associated liver disease.
