What are the management strategies for Alcohol-Related Liver Disease (ALD)?

From the Guidelines

Alcohol abstinence is the cornerstone of treatment for Alcohol-Related Liver Disease (ALD), and patients should be advised and encouraged to achieve complete abstinence to reduce the risk of liver-related complications and mortality. Management of ALD requires a multidisciplinary approach, including referral to addiction specialists and support groups like Alcoholics Anonymous. Medications such as acamprosate (666 mg three times daily), naltrexone (50 mg daily), or baclofen (5-10 mg three times daily) can help maintain sobriety 1.

Key Components of ALD Management

• Nutritional support is essential, with a high-protein diet (1.2-1.5 g/kg/day) and vitamin supplementation including thiamine (100 mg daily for at least 3-5 days), folate, and B-complex vitamins 1.
• For alcoholic hepatitis, corticosteroids like prednisolone (40 mg daily for 28 days) may benefit severe cases with Maddrey's Discriminant Function >32, though they're contraindicated in active infection, gastrointestinal bleeding, or renal failure 1.
• N-acetylcysteine (150 mg/kg IV loading, then 100 mg/kg daily for 5-7 days) can be added to steroids in severe cases.
• Management of complications includes diuretics (spironolactone 100-400 mg daily with furosemide 40-160 mg daily) for ascites, prophylactic antibiotics like norfloxacin (400 mg daily) for spontaneous bacterial peritonitis prevention, and beta-blockers such as propranolol (20-40 mg twice daily) for varices.

Considerations for Liver Transplantation

Liver transplantation should be considered for end-stage liver disease after 6 months of documented abstinence, with 5-year survival rates exceeding 70% in carefully selected patients. The most recent and highest quality study, the EASL clinical practice guidelines from 2018 1, emphasizes the importance of complete abstinence from alcohol to reduce the risk of liver-related complications and mortality.

General Measures

Regardless of the severity, alcohol abstinence is the cornerstone of therapy, and early management of AUD is recommended in all patients with AH 1. Supplementation with B-complex vitamins is recommended to prevent Wernicke’s encephalopathy. Other general approaches include treatment of hepatic encephalopathy and treatment of ascites. Patients with severe AH are at risk of developing acute kidney injury, and measures aimed at preventing the development of renal failure are recommended.

Management Strategies for Alcohol-Related Liver Disease (ALD)

The management of ALD involves a combination of lifestyle changes, medical therapies, and in some cases, liver transplantation. Some key strategies include:

• Alcohol abstinence: This is the most effective measure to improve prognosis in patients with ALD, as continued alcohol consumption can lead to disease progression and increased mortality 2, 3, 4, 5.
• Nutritional support: Providing enteral nutrition can help manage the complications of liver failure and support the patient's overall health 3, 4.
• Medical therapy: Therapies targeting oxidative stress, gut-liver axis, inflammatory response inhibition, and liver regeneration enhancement may play a role in ALD management 3.
• Liver transplantation: This is the only approach that can improve prognosis in patients with advanced ALD who are non-responsive to medical therapy, and should be considered in patients with decompensated cirrhosis 2, 4, 6.
• Management of alcohol use disorder (AUD): The combination of psychosocial interventions, pharmacological therapy, and medical management is the most effective treatment for AUD, but its effectiveness in patients with ALD is uncertain due to concerns about liver safety 5.

Diagnosis and Assessment

Diagnosis of ALD is based on a combination of clinical presentation, laboratory tests, and imaging studies. Some key diagnostic tools include:

• Liver biopsy: This remains the gold-standard diagnostic tool for ALD, but non-invasive alternatives such as biochemical tests and liver stiffness measurement are increasingly being used 3, 4.
• Questionnaires and laboratory tests: These can be used to screen for alcohol intake and assess the severity of ALD 4.
• Scoring systems: These can be used to assess the severity of alcoholic hepatitis (AH) and allocate resources for treatment 4, 6.

Special Considerations

Some special considerations in the management of ALD include:

• Alcoholic hepatitis (AH): This is a severe clinical presentation of ALD that requires early recognition and specialized tertiary medical care 2, 4, 6.
• End-stage ALD (ESALD) and severe acute alcohol-related hepatitis (SAAH): These conditions may require liver transplantation, and management should involve a multidisciplinary team of hepatologists, addiction specialists, and other healthcare professionals 6.
• Polydrug addicts: This population requires special consideration due to the potential for increased liver damage and other complications 6.
