Management of Hepatitis in Adults

Immediate Diagnostic Classification Required

The first critical step is determining which type of hepatitis is present, as management differs fundamentally between hepatitis A, B, C, autoimmune hepatitis, and acute versus chronic presentations. 1

Essential Initial Testing

  • Test for HBsAg, anti-HBc, HCV antibody, HCV RNA, and anti-HAV IgM to differentiate between hepatitis A, B, and C 1, 2, 3
  • Measure quantitative HBV DNA if HBsAg is positive to assess viral replication status 1, 2
  • Check ALT, AST, bilirubin, INR, and albumin to assess severity and hepatic synthetic function 1
  • Obtain autoimmune markers (ANA, ASMA, IgG levels) if viral serologies are negative and autoimmune hepatitis is suspected 1
  • Assess for cirrhosis using liver stiffness measurement (FibroScan) or calculate APRI score, as presence of cirrhosis fundamentally changes management 1

Hepatitis B Management

Treatment Indications (Prioritize These Criteria)

Initiate antiviral therapy immediately with entecavir 0.5 mg daily OR tenofovir (TDF or TAF) in the following patients: 1, 2

  • Any patient with cirrhosis and detectable HBV DNA (any level) 1, 2
  • HBV DNA ≥2,000 IU/mL AND ALT >2× ULN 1, 2
  • HBV DNA ≥2,000 IU/mL AND liver stiffness ≥9 kPa (with normal ALT) or ≥12 kPa (with ALT <5× ULN), indicating at least moderate fibrosis 2
  • Decompensated cirrhosis with any detectable HBV DNA - these patients also require immediate liver transplant evaluation 1, 2
  • HBeAg-positive patients over age 30 with persistently normal ALT and high HBV DNA, as delayed HBeAg seroconversion beyond age 30 increases HCC risk 1, 2

Severe Acute Hepatitis B

For patients with acute hepatitis B and coagulopathy (INR >1.5) or protracted course (>4 weeks of symptoms), immediately start nucleos(t)ide analogue therapy and evaluate for liver transplantation. 1 More than 95% of adults with uncomplicated acute hepatitis B recover spontaneously without treatment and do not require antiviral therapy. 1

First-Line Treatment Agents

Use entecavir 0.5 mg daily OR tenofovir (TDF 300 mg or TAF 25 mg) daily - these have high barriers to resistance. 1, 2 Avoid lamivudine due to resistance rates up to 70% at 5 years. 2 Treatment is typically indefinite, as stopping therapy leads to high relapse rates. 1, 2

Monitoring on Treatment

  • HBV DNA every 3 months until undetectable, then every 6 months 2
  • ALT/AST every 3-6 months 2
  • Annual quantitative HBsAg to assess for functional cure (HBsAg loss) 2
  • Renal function monitoring if on tenofovir 2

HCC Surveillance

Perform ultrasound every 6 months for high-risk patients: Asian men >40 years, Asian women >50 years, any patient with cirrhosis, family history of HCC, or age >40 with persistent ALT elevation. 2

Special Populations

For patients requiring immunosuppressive therapy or chemotherapy, start antiviral prophylaxis 2-4 weeks before treatment and continue through treatment plus 6-12 months after completion (24 months for rituximab). 2 The reactivation risk is 12-50% without prophylaxis. 2

For HBV/HCV coinfection, there is risk of HBV reactivation during DAA therapy for HCV - ensure effective nucleos(t)ide analogue therapy is in place before starting HCV treatment. 1

Hepatitis C Management

All Patients with Positive HCV RNA

Refer immediately to a specialist with hepatitis C expertise, as cure rates exceed 95% with modern direct-acting antivirals (DAAs). 1, 4 Active substance use is NOT a contraindication to treatment. 4

Treatment Regimens (Based on FDA-Approved Sofosbuvir Label)

For genotype 1 or 4 without cirrhosis or with compensated cirrhosis: Sofosbuvir + peginterferon alfa + ribavirin for 12 weeks 3

For genotype 2 without cirrhosis or with compensated cirrhosis: Sofosbuvir + ribavirin for 12 weeks 3

For genotype 3 without cirrhosis or with compensated cirrhosis: Sofosbuvir + ribavirin for 24 weeks 3

For genotype 1 patients ineligible for interferon: Sofosbuvir + ribavirin for 24 weeks can be considered 3

Critical Pre-Treatment Testing

Test ALL patients for HBsAg and anti-HBc before starting DAA therapy, as HBV reactivation has caused fulminant hepatitis, hepatic failure, and death in HCV/HBV coinfected patients. 3 The FDA issued a black box warning about this risk. 1, 3

Monitoring During Treatment

If quantitative HCV viral load is detectable at week 4, repeat at week 6 - if viral load increases >10-fold (>1 log10 IU/mL), discontinue treatment. 1

Post-SVR Management

For patients achieving sustained virological response (SVR): 1

  • No additional follow-up needed if no advanced fibrosis (Metavir F0-F2) 1
  • Continue HCC surveillance with ultrasound every 6 months if cirrhosis (Metavir F3-F4) is present 1
  • Continue endoscopy screening for varices if cirrhosis is present 1

Decompensated Cirrhosis

Refer immediately to a liver transplant center for patients with decompensated cirrhosis (Child-Pugh B or C). 1 Ledipasvir/sofosbuvir + ribavirin for 12 weeks achieved 96% SVR in compensated cirrhosis but lower rates (85% for Child-Pugh B, 60% for Child-Pugh C). 1

Acute Hepatitis C

Monitor HCV RNA for at least 12-16 weeks to detect spontaneous clearance before starting treatment, as 15-45% clear spontaneously. 1 If treatment is initiated, use the same regimens as for chronic infection. 1

Autoimmune Hepatitis Management

First-Line Treatment

Initiate prednisone 0.5-1 mg/kg/day (up to 60 mg daily) combined with azathioprine 50-100 mg daily (1-2 mg/kg). 1 This combination is superior to prednisone monotherapy in reducing steroid-related side effects. 1

Alternative induction strategy: Start with prednisone 60 mg daily alone for 1-2 weeks, then add azathioprine 50 mg, increasing to 100 mg after 2 weeks. 1 This approach helps distinguish azathioprine hepatotoxicity from primary non-response. 1

Tapering Schedule (for 60 kg patient)

  • Week 1: Prednisone 60 mg daily
  • Week 2: Prednisone 50 mg daily
  • Week 3: Prednisone 40 mg daily + Azathioprine 50 mg daily
  • Week 4: Prednisone 30 mg daily + Azathioprine 50 mg daily
  • Week 5-6: Prednisone 25-20 mg daily + Azathioprine 100 mg daily
  • Week 7-8: Prednisone 15 mg daily + Azathioprine 100 mg daily
  • Week 10+: Prednisone 10 mg daily + Azathioprine 100 mg daily
  • Taper to 7.5 mg, then 5 mg at 3-month intervals if transaminases normalize 1

Acute Severe Autoimmune Hepatitis or Acute Liver Failure

For acute severe AIH (coagulopathy with INR >1.5 or protracted course >4 weeks), give prednisone 0.5-1 mg/kg daily (up to 2 mg/kg in children) as a treatment trial. 1 If no improvement in laboratory tests or clinical worsening occurs within 1-2 weeks, abandon glucocorticoid therapy and proceed immediately to liver transplant evaluation. 1

For AIH with acute liver failure (hepatic encephalopathy present), evaluate directly for liver transplantation rather than prolonged glucocorticoid treatment, as glucocorticoids have not improved survival in this setting. 1

Treatment Response Monitoring

Serum aminotransferases should improve within 2 weeks of starting treatment. 1 Biochemical remission achieved within 6 months is associated with significantly lower progression to cirrhosis or need for transplantation. 1

Second-Line Therapy

For inadequate response or intolerance to azathioprine, use mycophenolate mofetil (MMF) 1-2 g daily in divided doses. 1 MMF combined with prednisone was superior to azathioprine/prednisone in normalizing ALT, AST, and IgG levels. 1

Hepatitis A Management

More than 95% of adults with acute hepatitis A recover spontaneously without specific treatment. 5 Management is supportive with monitoring for severe disease. 5

Supportive Care

  • Counsel on alcohol abstinence and avoiding hepatotoxic drugs (including acetaminophen) 1
  • Monitor for coagulopathy (INR >1.5) or protracted course (>4 weeks), which indicate severe disease requiring transplant evaluation 1
  • No antiviral therapy is indicated for uncomplicated acute hepatitis A 5

Prevention in Hepatitis B Patients

Vaccinate all HBV-infected patients against hepatitis A if anti-HAV negative, as HAV/HBV coinfection increases mortality 5.6- to 29-fold. 2

Common Pitfalls to Avoid

  • Do not delay treatment in cirrhotic patients with any detectable HBV DNA - these patients require immediate antiviral therapy regardless of ALT levels 1, 2
  • Do not use lamivudine or adefovir as first-line HBV therapy due to high resistance rates 1, 2
  • Do not start HCV DAA therapy without screening for HBV - reactivation can be fatal 1, 3
  • Do not continue glucocorticoids beyond 1-2 weeks in acute severe autoimmune hepatitis without improvement - this delays necessary transplantation 1
  • Do not withhold HCV treatment from patients with active substance use - cure rates are equivalent and treatment prevents transmission 4
  • Do not stop nucleos(t)ide analogue therapy in HBV patients without close monitoring - relapse rates are extremely high 1
