What are the next steps for a patient with Sustained Virologic Response (SVR) at 730 days after hepatitis C treatment?

Management of Patients with Sustained Virologic Response at 730 Days After Hepatitis C Treatment

For patients who have achieved SVR at 730 days (2 years) after hepatitis C treatment, no further HCV RNA testing is recommended as they can be considered cured of HCV infection, though patients with advanced fibrosis or cirrhosis require ongoing surveillance for hepatocellular carcinoma.

Post-SVR Monitoring Strategy Based on Fibrosis Stage

For Patients Without Advanced Fibrosis (F0-F2)

• No further HCV RNA testing is required after confirming SVR at 730 days 1
• Patients can be discharged from hepatitis C-specific care 1, 2
• No surveillance for hepatocellular carcinoma (HCC) is recommended 1
• Routine liver function tests are no longer necessary unless there are other causes of liver disease

For Patients With Advanced Fibrosis or Cirrhosis (F3-F4)

• Continued surveillance for HCC with ultrasound ± AFP every 6 months indefinitely 1
• Endoscopic surveillance for esophageal varices:
  • If no varices or small varices were found on initial screening, repeat endoscopy at 2-3 years 1, 2
  • If no varices are identified 2-3 years post-SVR and no risk factors for progressive cirrhosis exist, cessation of further endoscopic screening can be considered 1
• Monitoring for complications of cirrhosis should continue despite achieving SVR 1

Risk of Late Relapse

The risk of late HCV relapse after SVR at 730 days is extremely rare:

• Studies show that late relapse beyond 24 weeks post-treatment occurs in <1% of patients 1, 3
• Most relapses occur within the first 12-24 weeks after completing therapy 4, 3
• Patients with ongoing risk factors for reinfection (injection drug use, high-risk sexual behaviors) should undergo annual HCV RNA testing 1, 2

Assessment for Other Causes of Liver Disease

• Patients who have achieved SVR should be counseled regarding other sources of liver injury that can independently contribute to liver fibrosis progression 1:
  • Alcohol consumption
  • Nonalcoholic fatty liver disease
  • Medications with hepatotoxic potential
  • Other viral hepatitis (HBV, HDV)
• If liver enzymes remain elevated despite SVR, evaluate for these alternative causes 2

Fibrosis Assessment Post-SVR

• Non-invasive assessment of liver fibrosis (e.g., transient elastography) can be considered to evaluate for fibrosis regression 1
• Improved fibrosis measurements should not alter the frequency of HCC surveillance in patients with pre-treatment advanced fibrosis or cirrhosis 1

Special Considerations

• For patients previously treated with interferon-based therapy, thyroid function tests (TSH, free thyroxine) should be assessed at 1 and 2 years after treatment 1, 2
• Patients with HIV coinfection may require closer monitoring as immunosuppression could theoretically increase risk of late relapse 5

This structured approach ensures appropriate follow-up based on pre-treatment liver disease severity, optimizing patient outcomes while avoiding unnecessary testing in those at low risk for complications.
