Update on Hepatitis B & C -Postgraduate Course

Update on Hepatitis B –Jean Pappas Molleston

Hepatitis B: Who to Treat:

  • Immune active Hepatitis B with active disease: HBeAg+ (> 6 months), HBV DNA > 20,000 IU/ml, ALT > 1.5 x normal or > 60 IU/L, &  moderate/severe inflammation/fibrosis
  • Reactivated Hepatitis B with active disease: HBeAg‐ (> 12 months), HBV DNA > 2000 IU/ml, ALT > 1.5 x normal or > 60 IU/L

Hepatitis B: Who to Not Treat:

  • Immunotolerant Hepatitis B: HBeAg+, HBV DNA > 20,000 IU/ml, Normal ALT
  • Inactive carrier: HBe Ag, HBV DNA < 2000

What to Use to Treat Children with Hepatitis B and When:

  • Only children with active disease should be treated
  • Many would suggest IFN as a first line drug, especially for younger children
  • Nucleoside analogues can now be considered in older children: Tenofovir is licensed for over age 12,  Entecavir is licensed for over age 16

What’s Exciting?

  • NCT01519960 Peg‐IFN monotherapy for children with chronic active hepatitis B
  • NCT01368497 Peg‐IFN and Entecavir for treatment of Hepatitis B in immunotolerant children
  • New drugs
  • New ways to predict who will have worse disease and who will respond
  • Direct Acting Antivirals

Treating HCV: 2013 and Beyond… Regino P. González-Peralta, M.D.

Standard of Care HCV Therapy: Children

  1. IFN/PEG-IFN-α-2a (PEG-2a):  ‘‘Branched’’ 40-kDa PEG moiety, Dose: 104 μg/m2 SQ once weekly, Available: prefilled syringes or as vials
  2. PEG-IFN-α-2b (PEG-2b): ‘‘Linear’’ 12-kDa PEG, Dose: 60 μg/m2 SQ once weekly, Available: Measured vials/ready-use pens

Other pointers:

  • Discussed IL-28 B Polymorphism –No pediatric data yet
  • Close monitoring for those who are treated
  • PEG-RBV is standard of care for children though with suboptimal efficacy and significant toxicity
  • Warp-speed evolution of HCV therapies
  • All ORAL’ regimen on horizon
  • Yearly evaluation: CBC, liver tests, HCV RNA and PT/INR (cirrhosis)

HCV Rx in Children: to treat or not:

IN FAVOR…

  • Avoid disease progression
  • Remove social stigma
  • Decrease HCV burden
  • Children ‘better’ candidates

…AGAINST

  • Benign disease
  • Efficacy
  • Toxicity
  • Direct Acting Antivirals (in the pipeline)
