Treatment for Chronic Liver Disease
The treatment of chronic liver disease must target the specific underlying etiology—antiviral therapy for viral hepatitis, complete abstinence for alcoholic liver disease, and lifestyle modifications for non-alcoholic fatty liver disease—while simultaneously managing complications such as hepatic encephalopathy, ascites, variceal bleeding, and malnutrition. 1
Etiology-Specific Treatment Approaches
Chronic Hepatitis B
- First-line antiviral agents include entecavir, tenofovir, or peginterferon alfa-2a for patients with elevated ALT and HBV DNA ≥2000 IU/mL 1, 2
- All patients with cirrhosis and detectable HBV DNA require treatment regardless of ALT levels to prevent hepatic decompensation 1
- Monitor HBV DNA and ALT levels every 3-6 months during therapy, and assess for virologic breakthrough and renal function in patients on nucleos(t)ide analogues 1
- Lifelong therapy is typically required for HBV-related cirrhosis 1
Chronic Hepatitis C
- Direct-acting antivirals (DAAs) have revolutionized treatment with high cure rates and should be used as first-line therapy 1
- Patients with HCV-associated cirrhosis and HCC maintain high recurrence rates even after achieving sustained viral response with DAA therapy 1
Non-Alcoholic Fatty Liver Disease (NAFLD/NASH)
- Weight loss of 7-10% through caloric restriction and regular physical activity improves liver histology, reduces inflammation, and can improve fibrosis 1
- A Mediterranean diet pattern reduces liver fat even without weight loss 1
- At least 150-300 minutes of moderate-intensity aerobic exercise per week is beneficial 1
- When steatosis and steatohepatitis coexist with other chronic liver diseases, assess for metabolic risk factors and alternate etiologies 1
Alcoholic Liver Disease
- Complete abstinence from alcohol is mandatory and represents the cornerstone of treatment 1
- Potential for improvement exists in acute alcoholic hepatitis with appropriate management 3
Management of Complications
Hepatic Encephalopathy
- Identify and treat precipitating factors including infection, gastrointestinal bleeding, constipation, diuretics, and electrolyte disturbances 3
- Lactulose remains first-line therapy targeting 2-3 bowel movements per day 2, 4
- Rifaximin leads to better maintenance of remission and decreased readmission rates in patients with cirrhosis and hepatic encephalopathy 4
- Brain imaging should be performed in every patient with CLD and unexplained alteration of brain function to exclude structural lesions 3
- Monitor neurological manifestations to adjust treatment and investigate for minimal or covert hepatic encephalopathy 3
Critical caveat: Lactulose and rifaximin are contraindicated in acute liver failure—these agents are only indicated for hepatic encephalopathy in chronic liver disease/cirrhosis 5
Ascites and Fluid Management
- Sodium intake should not be reduced below 60 mmol/d in patients with ascites 1
- Mild ascites and peripheral edema should begin with sodium and water restriction, followed by careful diuresis 6
- Large-volume paracentesis with albumin infusion prevents circulatory dysfunction in severe cases 2, 6
- Diagnostic paracentesis should be performed if ascites is present to rule out spontaneous bacterial peritonitis 5
Variceal Bleeding Prevention and Management
- Patients with cirrhosis should undergo endoscopic screening for esophageal varices 2
- Prophylactic treatment with beta-blockers or endoscopic variceal ligation prevents variceal bleeding 2
- Carvedilol reduces the rate of initial bleeding compared with band ligation in primary prophylaxis 4
- Control acute bleeding using a stepwise approach from least to most invasive strategies 6
Hepatorenal Syndrome
- Terlipressin currently appears to be the best medical therapy available for type 1 hepatorenal syndrome 4
- The addition of albumin to terlipressin decreases mortality in patients with type 1 HRS 4
- Patients with type I hepatorenal syndrome should have expedited referral for liver transplantation 1
- Treatment should be initiated early to prevent progression of renal failure 6
Infection Prevention and Management
- Empiric broad-spectrum antimicrobial therapy should be used for spontaneous bacterial peritonitis, bacterial and fungal sepsis, and cholangitis after obtaining appropriate cultures 6
- Managing complications of cirrhosis including spontaneous bacterial peritonitis and GI bleeding should follow available guidelines 3
Nutritional Management
Protein and Energy Requirements
- Provide adequate protein intake (1.2-1.5 g/kg/day) to favor positive nitrogen balance and increase muscle mass 2
- Weight loss with sarcopenia may worsen hepatic encephalopathy 3
- Provide enough protein and energy to prevent muscle wasting 3
Vitamin and Mineral Supplementation
- Vitamin D supplementation is recommended for levels below 20 ng/ml to achieve levels above 30 ng/ml 1, 2
- Vitamin K supplementation should be considered in patients with jaundice or cholestatic liver disease 1
- Water-soluble vitamin deficiencies may develop rapidly; multivitamin supplementation is reasonable in decompensated patients 1
- Calcium and vitamin D supplementation is recommended for all patients with chronic liver disease 1
Monitoring and Surveillance
Hepatocellular Carcinoma Screening
- Ultrasonography every 6 months is required for HCC surveillance in patients with advanced fibrosis or cirrhosis 3, 2
- Lifelong HCC surveillance is required for cirrhotic patients, even after viral clearance 1
Regular Follow-up
- Patients with chronic liver disease should receive regular work-up at least every 6-12 months 3
- Out-patient consultations should be planned to adjust treatment and prevent reappearance of precipitating factors 3
- Close liaison with family, general practitioner, and other caregivers ensures all parties understand management strategies 3
Bone Health Assessment
- Bone densitometry should be evaluated in patients with previous fragility fractures, those treated with corticosteroids, and before liver transplantation 1
- Bisphosphonates may be considered for patients with established osteoporosis, particularly those with primary biliary cholangitis 1
Liver Transplantation Considerations
Patients with cirrhosis should be referred for transplantation when they develop evidence of hepatic dysfunction or experience their first major complication 1
- Every therapeutic option should be carefully considered before committing to transplantation due to the need for long-term immunosuppressive therapy 1
- Patients with decompensated cirrhosis should be evaluated for liver transplantation 3
- Early treatment of underlying liver diseases before progression to cirrhosis is the most effective approach for preventing HCC and liver-related mortality 1
Patient and Caregiver Education
Education should include: 3
- Effects of medications (lactulose, rifaximin) and potential side effects (diarrhea)
- Importance of medication adherence
- Early signs of recurring hepatic encephalopathy
- Actions to take if recurrence occurs (anticonstipation measures for mild recurrence, referral to general practitioner or hospital if hepatic encephalopathy with fever)
