Alcohol use disorder and the liver.

Area of Science:

• Hepatology
• Addiction Medicine
• Public Health

Background:

• Alcohol use disorders (AUD) lead to significant physical harm, with alcohol-related liver disease (ALD) causing a substantial portion of alcohol-related mortality.
• ALD encompasses a spectrum of liver damage, from steatosis to cirrhosis, with no specific cure for cirrhosis itself.
• Hepatocellular carcinoma (HCC) and alcoholic hepatitis are severe complications of ALD, carrying high mortality rates.

Purpose of the Study:

• To highlight the critical link between alcohol use disorders and alcohol-related liver disease.
• To emphasize the progressive nature of ALD and its severe complications.
• To underscore the need for integrated care models for patients with comorbid AUD and ALD.

Main Methods:

• Review of existing literature on alcohol use disorders and alcohol-related liver disease.
• Analysis of the progression of liver pathology in ALD.
• Examination of current treatment limitations and intervention gaps.

Main Results:

• Alcohol consumption has an exponential relationship with ALD risk, influenced by genetics, lifestyle, and social factors.
• Abstinence is crucial for managing ALD progression, though cirrhosis and its complications like HCC and alcoholic hepatitis have limited treatment options.
• While effective interventions exist for AUD, few have been tested in patients with comorbid ALD.

Conclusions:

• Integrated specialist alcohol and hepatology services are essential for developing effective interventions and care pathways for patients with ALD and ongoing AUD.
• Addressing the complex interplay between AUD and ALD requires collaborative, multidisciplinary approaches.
• Further research is needed to adapt and trial existing AUD interventions for patients with liver disease.
