What are the treatment options for chronic liver disease (CLD)?

Treatment of Chronic Liver Disease

Treat the Underlying Cause First

The cornerstone of chronic liver disease management is targeting the specific underlying etiology with disease-specific therapies, as this is the only approach proven to prevent progression to cirrhosis and reduce liver-related mortality. 1

Viral Hepatitis B

For chronic hepatitis B, treatment decisions depend on disease stage and viral activity:

• Patients with cirrhosis (compensated or decompensated) and any detectable HBV DNA must receive treatment immediately with entecavir or tenofovir as first-line monotherapy 2, 1
• For non-cirrhotic patients, initiate treatment when ALT is elevated and HBV DNA ≥2000 IU/mL 1
• Entecavir dosing differs by cirrhosis status: 1 mg daily for decompensated cirrhosis versus 0.5 mg daily for compensated disease 2
• Therapy should be continued indefinitely in cirrhotic patients due to proven long-term benefits in preventing decompensation and reducing HCC incidence 2, 1
• Monitor HBV DNA and ALT every 3-6 months during therapy, with renal function monitoring particularly important given multiple risk factors for impairment 2, 1
• Peginterferon alfa-2a is contraindicated in decompensated cirrhosis but can be used in well-compensated disease 2

Viral Hepatitis C

• Direct-acting antivirals (DAAs) have revolutionized HCV treatment with high cure rates and should be used as first-line therapy 1
• Prioritize treatment for patients with F3-F4 fibrosis (advanced fibrosis/cirrhosis) due to higher risk of complications 3
• Patients with decompensated cirrhosis (Child-Pugh B and C) require urgent treatment with interferon-free regimens 3
• Assess sustained virologic response (SVR) 12 weeks after treatment completion to confirm cure 3
• Continue HCC surveillance every 6 months in cirrhotic patients even after achieving SVR, as HCC risk is reduced but not eliminated 1, 3

Non-Alcoholic Fatty Liver Disease (NAFLD/NASH)

Lifestyle modification is the primary evidence-based treatment:

• Achieve 7-10% weight loss through caloric restriction and regular physical activity, which improves liver histology, reduces inflammation, and can improve fibrosis 1
• Implement a Mediterranean diet pattern, which reduces liver fat even without weight loss 1
• Prescribe at least 150-300 minutes of moderate-intensity aerobic exercise per week 1
• When steatosis coexists with other chronic liver diseases, assess for metabolic risk factors and alternate etiologies 1

Alcoholic Liver Disease

• Complete and permanent abstinence from alcohol is mandatory and represents the only proven therapy to prevent progression 1

Autoimmune Hepatitis

• Liver transplantation is indicated for decompensated cirrhosis not responding to medical therapy and for fulminant presentations 2

Genetic/Metabolic Diseases

Wilson's Disease:

• Medical treatment consists of copper-chelating agents (penicillamine, trientine, tetrathiomolybdate) or zinc salts 2
• Liver transplantation is indicated for acute liver failure or end-stage liver disease progression despite therapy 2
• Rule out non-compliance and incorrect dosing before declaring treatment failure 2
• Neuropsychiatric evaluation is mandatory before transplantation, as neurological symptoms may worsen post-transplant despite potential for recovery in 57-77% of cases 2

Hereditary Hemochromatosis:

• Therapeutic phlebotomy (500 ml/week) is the standard treatment when serum ferritin >1000 ng/ml, continued until iron stores normalize 2
• Liver transplantation is indicated for hepatic decompensation or HCC development 2
• Perform thorough cardiac evaluation before transplantation due to cardiomyopathy risk from iron overload 2

Management Based on Disease Stage

Pre-Cirrhotic Disease

• Treatment of the underlying cause can prevent progression to cirrhosis when initiated before advanced fibrosis develops 1
• Use transient elastography or liver biopsy to grade fibrosis and guide treatment urgency 2

Compensated Cirrhosis

• All patients with compensated cirrhosis require treatment of the underlying etiology to prevent decompensation 2, 1
• Screen for gastroesophageal varices according to established protocols 1
• Initiate HCC surveillance with ultrasound (or MRI/CT if available) every 6 months 2, 1

Decompensated Cirrhosis

• Refer immediately for liver transplantation evaluation when hepatic dysfunction develops or after the first major complication 1
• For HBV-related decompensation, use entecavir 1 mg daily or tenofovir with lifelong therapy 1
• Expedite transplant referral for type I hepatorenal syndrome 1

Management of Complications

Portal Hypertension and Variceal Bleeding

• Primary prevention of first variceal bleed: Non-selective β-blockers are standard in adults but not generally recommended in children 4
• Acute bleeding control: Use stepwise approach from least to most invasive (endoscopic therapy → pharmacologic therapy → TIPS → surgical shunts) 4
• Secondary prevention: Consider bypass operations, with meso-Rex bypass showing particular promise in pediatrics 4
• Carvedilol reduces initial bleeding rates compared with band ligation in primary prophylaxis 5
• Early TIPS placement in highly selected high-risk patients with acute variceal hemorrhage decreases long-term mortality 5

Hepatic Encephalopathy

• Rule out other causes of altered mental status first 4
• Identify and treat precipitating factors (infection, GI bleeding, constipation, medications, electrolyte abnormalities) 4
• Initiate lactulose as first-line empiric treatment 4
• Rifaximin maintains remission better than placebo and decreases readmission rates in patients with cirrhosis and hepatic encephalopathy 5
• Additional options include sodium benzoate and flumazenil for refractory cases 4

Ascites

• Mild ascites: Begin with sodium restriction (not below 60 mmol/day) and water restriction 1, 4
• Moderate ascites: Add careful diuresis with spironolactone and furosemide 4
• Severe/refractory ascites: Perform large-volume paracentesis with albumin infusion (8g per liter removed) 4
• Avoid propranolol in patients with refractory ascites, as it is associated with poorer outcomes 5
• Satavaptan (vasopressin receptor antagonist) showed efficacy for refractory ascites but is not FDA-approved 5

Hepatorenal Syndrome

• Initiate treatment early to prevent progression of renal failure 4
• Terlipressin plus albumin is the best available medical therapy for type 1 HRS and decreases mortality 4, 5
• Provide general supportive measures and screen for sepsis with empiric antibiotics if suspected 4
• Consider renal replacement therapy if medical management fails 4

Spontaneous Bacterial Peritonitis

• Start empiric broad-spectrum antibiotics immediately after obtaining cultures (typically third-generation cephalosporin) 4
• Adjust therapy based on culture sensitivities 4

Pruritus

• First-line: Bile acid binding agents (cholestyramine) 4
• Second-line options: Rifampin, ursodeoxycholic acid, antihistamines 4, 2
• Additional options: Phenobarbital, carbamazepine 4
• Refractory cases: Consider partial external biliary diversion 4

Nutritional and Metabolic Management

Vitamin Supplementation

• Vitamin D: Supplement when levels <20 ng/ml to achieve >30 ng/ml, as deficiency correlates with disease severity 1
• Vitamin K: Consider supplementation in jaundice or cholestatic liver disease 1
• Water-soluble vitamins: Provide multivitamin supplementation in decompensated patients due to diminished hepatic storage 1
• Fat-soluble vitamins (A, D, E, K): Supplement in cholestatic diseases and after Kasai procedure for biliary atresia 4

Bone Health

• Perform bone densitometry in patients with previous fragility fractures, corticosteroid treatment, or before liver transplantation 1
• Provide calcium and vitamin D supplementation to all patients with chronic liver disease 1
• Consider bisphosphonates for established osteoporosis, particularly in primary biliary cholangitis 1

Nutritional Support

• Ensure adequate caloric supply and protein intake (avoid restriction even in encephalopathy) 4
• Provide mineral and trace element supplementation as needed 4

Special Populations

HIV-HBV Coinfection

• HIV-HBV coinfection carries 14-fold higher liver-related mortality than either infection alone 2, 1
• These patients have higher HBV DNA levels, more rapid progression to cirrhosis, and atypical serologic patterns 2
• Screen all HIV-positive, HBsAg-positive persons ≥20 years old for HCC twice annually (or any age with family history of HCC) 2
• Initiate CHB treatment in any patient with HIV-HBV coinfection using antiretroviral regimens that include anti-HBV activity 2

Chronic Kidney Disease

• Adjust antiviral dosing based on glomerular filtration rate 6
• Peginterferon alfa is not recommended when GFR <15 mL/min 6
• Ribavirin is contraindicated when GFR <50 mL/min 6
• Consider lower "normal" aminotransferase thresholds in dialysis patients to increase sensitivity for detecting liver disease 6

Liver Transplantation Indications

Refer for transplant evaluation when:

• Decompensated cirrhosis develops (ascites, variceal bleeding, encephalopathy, jaundice) 1
• MELD score indicates high mortality risk 1
• HCC within Milan criteria (single tumor <5 cm or up to 3 tumors <3 cm each) develops 2
• Type I hepatorenal syndrome occurs 1
• Acute liver failure from Wilson's disease, autoimmune hepatitis, or other causes 2
• Refractory complications despite optimal medical management 1

Important transplant considerations:

• Every therapeutic option should be exhausted before committing to transplantation due to lifelong immunosuppression requirements 1
• Cholangiocarcinoma should be excluded in PSC patients, as unsuspected cholangiocarcinoma carries high recurrence risk and poor prognosis 2
• Active inflammatory bowel disease should be controlled before transplantation in PSC patients 2
• Hepatopulmonary syndrome and portopulmonary hypertension are best managed by liver transplantation 4

Prevention Strategies

• Hepatitis B vaccination for all newborns and high-risk groups reduces HCC risk 1
• Early treatment of underlying liver disease before cirrhosis develops is the most effective approach for preventing HCC and liver-related mortality 1
• Lifelong HCC surveillance is required for cirrhotic patients, even after viral clearance 1

Common Pitfalls to Avoid

• Do not use lamivudine in cirrhotic patients due to high resistance risk that can cause clinical decompensation 2
• Do not restrict protein intake in hepatic encephalopathy, as this worsens malnutrition without improving outcomes 4
• Do not reduce sodium below 60 mmol/day in ascites, as excessive restriction is counterproductive 1
• Do not overlook drug interactions when prescribing antivirals; evaluate all concurrent medications 3
• Do not rely solely on ALT levels for disease staging, as significant fibrosis can occur with normal ALT 3
• Do not stop HCC surveillance after viral cure in cirrhotic patients 1, 3
