What are the signs and management options for a patient with Hepatitis C (HCV) related Chronic Liver Disease (CLD) and portal hypertension?

Hepatitis C-Related Chronic Liver Disease: Signs and Management

Clinical Signs and Assessment

Patients with HCV-related chronic liver disease require systematic evaluation for disease severity, with particular attention to signs of cirrhosis and portal hypertension, as these determine prognosis and management strategy. 1

Signs of Advanced Disease

Hepatic manifestations:

• Compensated cirrhosis may be asymptomatic but requires screening for complications 1
• Decompensated cirrhosis presents with jaundice, ascites, variceal hemorrhage, or hepatic encephalopathy 1
• Portal hypertension indicated by ultrasonographic findings, splenomegaly, thrombocytopenia, or varices 2
• Hepatocellular carcinoma (HCC) risk of 1-4% per year once cirrhosis is established 1

Extrahepatic manifestations (immunologic origin):

• Cryoglobulinemia, membranoproliferative glomerulonephritis, and porphyria cutanea tarda 1
• Other associations include seronegative arthritis, Sjögren syndrome, autoimmune thyroiditis, and lichen planus 1

Disease Severity Assessment

Non-invasive testing is now preferred over liver biopsy for fibrosis assessment: 1

• Vibration-controlled transient elastography (VCTE) liver stiffness measurement (LSM):
  • LSM <8 kPa suggests minimal fibrosis 1
  • LSM ≥10 kPa indicates advanced fibrosis/cirrhosis 1
  • LSM 8-10 kPa represents intermediate risk requiring additional evaluation 1
• FIB-4 score:
  • <1.45 suggests minimal fibrosis 1

  • 3.25 indicates advanced fibrosis/cirrhosis 1

  • 1.45-3.25 represents intermediate risk 1

Laboratory monitoring should include: 1

• Platelet count (surrogate for clinically significant portal hypertension) 1
• ALT levels (though these fluctuate and may be normal despite significant disease) 1
• Bilirubin and albumin (surrogates for hepatic function) 1
• HCV RNA quantification and genotype determination 1

Important caveat: Liver biopsy may still be indicated when non-invasive tests are contradictory or when mixed etiologies are suspected (HBV coinfection, metabolic syndrome, alcohol use, autoimmunity) 1

Management Strategy

Antiviral Treatment

All patients with chronic HCV should be offered direct-acting antiviral (DAA) therapy without delay, with priority given to those with significant fibrosis (F2-F4). 3

Modern DAA regimens achieve cure rates exceeding 95-97% across all genotypes: 3

• Cure is defined as sustained virological response (SVR12): undetectable HCV RNA 12 weeks after treatment completion 1, 3
• SVR represents permanent viral eradication in >99% of cases 1

Treatment benefits include: 3

• Prevention of cirrhosis, hepatic decompensation, HCC, and death 3
• Regression of hepatic fibrosis and reduced risk of portal hypertension complications 1
• Improved quality of life and removal of stigma 3

Critical caveat for advanced disease: Patients with established cirrhosis (F4) or advanced fibrosis (F3) remain at reduced but ongoing risk for HCC even after achieving SVR and require continued surveillance with ultrasound every 6 months indefinitely 3

Pre-Treatment Considerations

Before initiating DAA therapy: 4

• Test all patients for hepatitis B virus (HBV) by measuring HBsAg and anti-HBc, as HBV reactivation has been reported during HCV treatment, with some cases resulting in fulminant hepatitis, hepatic failure, and death 4
• Monitor patients with serologic evidence of HBV infection for clinical and laboratory signs of hepatitis flare during and after HCV treatment 4

Address cofactors that accelerate disease progression: 1

• Alcohol cessation is mandatory: even moderate intake (>10 g/day) enhances disease progression 1
• Delay treatment until alcohol or injection drug use has been discontinued for ≥6 months 1
• Evaluate and manage metabolic dysfunction-associated steatotic liver disease (MASLD) and diabetes 1

Contraindications to treatment: 5

• Moderate to severe hepatic impairment (Child-Pugh B or C) or any history of prior hepatic decompensation 5
• Pregnancy (if ribavirin is used) 1

Post-SVR Surveillance and Follow-Up

Patients without cirrhosis or with minimal fibrosis (LSM <8 kPa or FIB-4 <1.45) can be discharged to primary care after SVR if no other liver disease cofactors exist 1

Patients with advanced fibrosis or cirrhosis require ongoing specialized care: 1

• Laboratory testing every 6-12 months including platelet count, bilirubin, and albumin 1
• HCC surveillance with ultrasound every 6 months indefinitely for patients with cirrhosis or advanced fibrosis 3
• Continued monitoring for portal hypertension with non-invasive tests 1
• Screening for varices if clinically significant portal hypertension is suspected 1

Important consideration: Patients with clinically significant portal hypertension (HVPG ≥10 mmHg) at baseline remain at risk for liver decompensation within the first 5 years after treatment, regardless of achieving SVR, and require close monitoring 6

Management of Cofactors and Comorbidities

Patients with persistent cofactors after SVR require specialized follow-up: 1

• MASLD (hepatic steatosis plus cardiometabolic risk factors) 1
• Harmful alcohol intake (>20 g/day for women or >30 g/day for men) 1
• Counsel all patients on regular physical activity, healthy diet, avoiding weight gain, and refraining from alcohol 1

Biochemical markers should be monitored post-SVR: 7

• Persistently elevated liver enzymes after viral clearance may indicate ongoing inflammation from other causes or residual HCV-related inflammatory changes 7

Special Populations

Patients with compensated cirrhosis (Child-Pugh A) or evidence of advanced liver disease require enhanced monitoring during treatment: 5

• Perform hepatic laboratory testing as clinically indicated 5
• Monitor for signs of hepatic decompensation (jaundice, ascites, encephalopathy, variceal hemorrhage) 5
• Discontinue treatment if hepatic decompensation develops 5

Drug interaction precautions: 4

• Avoid P-gp inducers (rifampin, St. John's wort) as they significantly decrease DAA plasma concentrations 4
• Amiodarone coadministration is not recommended due to risk of serious symptomatic bradycardia, including fatal cardiac arrest 4
