Hepatitis C Treatment Criteria

All adults with chronic hepatitis C virus infection should be treated with direct-acting antivirals (DAAs) regardless of disease stage, as current pan-genotypic regimens achieve >95% cure rates with excellent safety profiles. 1

Universal Treatment Approach

The modern paradigm has shifted from selective treatment to universal treatment. There are no longer strict "criteria" that must be met before initiating therapy—the presence of chronic HCV infection itself is the indication for treatment. This approach is driven by:

  • Sustained virological response (SVR) rates exceeding 95% with current DAAs
  • Excellent safety and tolerability profiles
  • Prevention of cirrhosis, hepatocellular carcinoma, and liver-related mortality
  • Improved quality of life post-cure
  • Public health benefits through reduced transmission 2, 3

Pre-Treatment Assessment Required

Before initiating therapy, you must determine:

1. HCV Genotype

  • Guides regimen selection, though pan-genotypic options now available
  • Genotype 1a vs 1b distinction matters for certain older regimens (1a has higher relapse rates with some combinations) 4
  • Genotype 3 is historically most difficult to treat 4

2. Presence and Severity of Cirrhosis

  • No cirrhosis: Standard 8-12 week regimens
  • Compensated cirrhosis (Child-Pugh A): May require extended duration (12-24 weeks depending on regimen)
  • Decompensated cirrhosis (Child-Pugh B or C): Specific regimen selection required 1, 4

3. Renal Function (eGFR)

  • eGFR >30 ml/min/1.73 m²: All DAAs can be used without dose adjustment
  • eGFR <30 ml/min/1.73 m² or dialysis: Use glecaprevir/pibrentasvir or grazoprevir/elbasvir (genotype 1b only); avoid sofosbuvir-based regimens in severe renal impairment unless specifically indicated 1, 5

4. Treatment History

  • Treatment-naive vs treatment-experienced
  • Prior regimen type (interferon-based, protease inhibitor-containing, sofosbuvir-containing)
  • Treatment-experienced patients, especially with cirrhosis, often require longer duration (24 weeks vs 12 weeks) 4

Specific Treatment Recommendations by Genotype

Genotype 1a (Treatment-Naive)

  • Ledipasvir/sofosbuvir: 12 weeks (no cirrhosis) or 24 weeks (cirrhosis)
  • Paritaprevir/ritonavir/ombitasvir + dasabuvir + ribavirin: 12 weeks (no cirrhosis) or 24 weeks (cirrhosis)
  • Sofosbuvir + simeprevir: 12 weeks (no cirrhosis) or 24 weeks (cirrhosis)
    • Critical caveat: Check for NS3 Q80K polymorphism in cirrhotic patients—if present, avoid simeprevir and use alternative regimen 4

Genotype 1b (Treatment-Naive)

  • Ledipasvir/sofosbuvir: 12 weeks
  • Paritaprevir/ritonavir/ombitasvir + dasabuvir: 12 weeks (no ribavirin needed)
  • Sofosbuvir + simeprevir: 12 weeks (no cirrhosis) or 24 weeks (cirrhosis) 4

Genotype 2

  • Sofosbuvir + weight-based ribavirin: 12 weeks (no cirrhosis) or 16 weeks (cirrhosis) 4

Genotype 3

  • Sofosbuvir + weight-based ribavirin: 24 weeks (most challenging genotype) 4

Genotype 4

  • Ledipasvir/sofosbuvir: 12 weeks
  • Paritaprevir/ritonavir/ombitasvir + ribavirin: 12 weeks
  • Sofosbuvir + ribavirin: 24 weeks 4

Genotypes 5 or 6

  • Ledipasvir/sofosbuvir: 12 weeks 4

Special Populations

Severe Renal Impairment/Dialysis

  • Preferred regimens: Glecaprevir/pibrentasvir (all genotypes) or grazoprevir/elbasvir (genotype 1b only)
  • No dose adjustments needed
  • Treat in expert centers with multidisciplinary monitoring
  • For decompensated cirrhosis + severe renal impairment: Sofosbuvir/velpatasvir without ribavirin for 24 weeks 1

Decompensated Cirrhosis

  • With eGFR >30: Sofosbuvir/velpatasvir + ribavirin for 12 weeks (start ribavirin at 600 mg daily, adjust based on tolerance)
  • With eGFR <30: Sofosbuvir/velpatasvir without ribavirin for 24 weeks
  • Avoid simeprevir and paritaprevir/ritonavir/ombitasvir/dasabuvir in decompensated disease 1, 5

HBV Coinfection

  • Treat HCV first using standard regimens
  • Monitor for HBV reactivation during and after HCV treatment
  • May require HBV prophylaxis or treatment 1

Critical Contraindications and Drug Interactions

Absolute Contraindications

  • Severe renal impairment (eGFR <30) for most sofosbuvir-based regimens (except specific decompensated cirrhosis indication)
  • Decompensated cirrhosis for simeprevir and paritaprevir/ritonavir/ombitasvir/dasabuvir regimens 5

Drug-Drug Interactions

  • Paritaprevir/ritonavir regimens: Extensive CYP3A4 interactions (avoid with salmeterol and many other drugs)
  • Always check for DDIs before prescribing, particularly with immunosuppressants, antiretrovirals, cardiovascular medications 4, 6

Common Pitfalls to Avoid

  1. Don't delay treatment waiting for advanced fibrosis—treat at any stage
  2. Don't underdose ribavirin when required: 1000 mg (<75 kg) or 1200 mg (≥75 kg) 4
  3. Don't use 12-week regimens in cirrhotic treatment-experienced patients—extend to 24 weeks 4
  4. Don't forget Q80K testing in genotype 1a cirrhotic patients if using simeprevir 4
  5. Don't use sofosbuvir in severe renal impairment without specific indication 1
