Management of Chronic Liver Dysfunction
The management of chronic liver dysfunction requires a systematic approach focused on identifying the underlying cause, preventing disease progression, and treating complications to reduce morbidity and mortality.
Assessment and Diagnosis
Evaluate disease severity: Use specialized prognostic scores that account for hepatic and extrahepatic organ failures (NACSELD, CLIF-C, or AARC ACLF scores) rather than conventional scores like MELD or MELD-Na 1
Laboratory workup:
- Complete blood count, comprehensive metabolic panel
- Liver function tests (ALT, AST, ALP, GGT, bilirubin)
- Coagulation studies (PT/INR, factor V)
- Serum ammonia levels
- Blood glucose and lactate levels 1
Imaging:
Screen for common etiologies:
- Viral hepatitis (HBV, HCV)
- Alcohol-related liver disease
- Metabolic syndrome and non-alcoholic fatty liver disease
- Autoimmune liver diseases
- Hereditary disorders (hemochromatosis, Wilson's disease, alpha-1 antitrypsin deficiency) 1
Management Strategy
1. Treat the Underlying Cause
Viral hepatitis:
Alcohol-related liver disease:
- Complete alcohol cessation is essential 3
- Consider addiction counseling and support groups
Metabolic-associated fatty liver disease:
- Weight loss through diet and exercise
- Management of diabetes, hypertension, and dyslipidemia
2. Prevent Disease Progression
Serial monitoring:
- Regular assessment of liver function tests
- Periodic calculation of prognostic scores to track disease progression 1
- Monitor for development of complications
Post-viral hepatitis monitoring:
- Continue hepatological follow-up despite successful antiviral therapy
- Screen for additional factors of chronic liver damage 1
3. Manage Complications
Hepatic Encephalopathy (HE)
For altered mental status:
- Protect airway to prevent aspiration
- Transfer to monitored setting if necessary
- Investigate cause of altered mental status
- Determine and treat precipitating factors
- Provide empiric therapy for suspected HE 1
Treatment:
Portal Hypertension and Related Complications
Ascites management:
- Sodium restriction
- Combination of aldosterone antagonist and loop diuretics
- Large-volume paracentesis with albumin for refractory ascites 3
Variceal bleeding prevention:
- Nonselective β-blockers (carvedilol or propranolol) 3
- Endoscopic surveillance and therapy as indicated
Spontaneous bacterial peritonitis (SBP):
- Prophylactic antibiotics for high-risk patients
- Prompt treatment when diagnosed
Hepatorenal Syndrome
- Management:
- Terlipressin improves reversal rates 3
- Albumin administration
- Avoid nephrotoxic medications
Bone Disease
- Prevention and treatment:
- Calcium supplements (1,000-1,500 mg/day)
- Vitamin D supplements (400-800 IU/day)
- Consider bisphosphonates for patients with osteoporosis 1
4. Consider Liver Transplantation
- Early referral for transplant evaluation in appropriate candidates
- Particularly important for patients with:
- Decompensated cirrhosis
- Acute-on-chronic liver failure
- Hepatocellular carcinoma 3
Monitoring and Follow-up
Regular surveillance:
- Hepatocellular carcinoma screening (ultrasound ± alpha-fetoprotein every 6 months)
- Endoscopic surveillance for varices
- Bone densitometry every 2-3 years (or yearly in high-risk patients) 1
Quality of life assessment:
- Evaluate and treat common symptoms like muscle cramps, pruritus, sleep disturbances, and sexual dysfunction 4
Prognosis
The development of decompensation significantly worsens prognosis, with median survival decreasing from >12 years in compensated cirrhosis to approximately 2 years after decompensation. Progression to acute-on-chronic liver failure further increases mortality risk 3.
Important Considerations
- Medication management: Avoid unnecessary medications and adjust dosages for hepatic impairment
- Infection prevention: Patients with chronic liver dysfunction are immunocompromised and at higher risk for infections
- Nutritional support: Maintain adequate protein intake unless severe encephalopathy is present
- Patient education: Educate patients about medication effects, early signs of complications, and when to seek medical attention 1
