Summary

Recurrent hepatitis B virus (HBV) after liver transplant (LT) is common. Combination therapy with Hepatitis B immunoglobulin (HBIG) and lamivudine reduces recurrence, but newer antivirals require further study.

Area of Science:

  • Hepatology
  • Transplant Immunology
  • Virology

Background:

  • Recurrent hepatitis B virus (HBV) infection post-liver transplant (LT) leads to significant graft and patient loss without effective immunoprophylaxis.
  • Monotherapy with Hepatitis B immunoglobulin (HBIG) or lamivudine reduces HBV recurrence but allows for resistant mutant emergence in up to 25% of cases.

Purpose of the Study:

  • To review the efficacy of current prophylaxis and treatment strategies for recurrent HBV post-LT.
  • To identify the need for further research into optimal dosing, duration, and novel antiviral agents for managing post-transplant HBV.

Main Methods:

  • Review of existing literature on HBV prophylaxis and treatment in liver transplant recipients.
  • Analysis of recurrence rates associated with different therapeutic regimens, including monotherapies and combination therapies.

Main Results:

  • Combination therapy with HBIG and lamivudine demonstrates higher efficacy, reducing HBV recurrence rates to 0-18% compared to monotherapies.
  • Lamivudine shows initial promise but is limited by rapid viral resistance during prolonged treatment.
  • Adefovir dipivoxil presents a promising alternative, necessitating further investigation in the post-LT setting.

Conclusions:

  • Combination HBIG and lamivudine is more effective than monotherapy in preventing recurrent HBV post-LT.
  • Established recurrent HBV treatment remains challenging, with newer agents like adefovir dipivoxil showing potential.
  • Further research is crucial to optimize treatment regimens and evaluate novel antivirals for post-liver transplant HBV management.
