  • Currently Hepatitis B (HBV) cannot be cured but it can be managed. Current (2015) standard of care is nucleos(t)ide analogs (NUCs) such as https://en.wikipedia.org/wiki/Te… or Entecavir or Pegylated interferon (IFN-alpha-2a).
  • These Rx suppress HBV replication and limit disease progression (1, 2).
  • If left untreated, HBV disease can lead to liver cirrhosis and HCC (hepatocellular carcinoma) so Rx is important .
  • Knowledge of side-effects of current Rx is also important since risk factors need to be considered for each individual patient based on their medical history and disease profile.

Side-effects of pegylated interferon

  • Usually given for 48 weeks, pegylated interferon produces many side-effects so it’s not and shouldn’t be given long-term.
  • These side-effects include fatigue, flu-like symptoms, mood swings, bone marrow suppression, and development or exacerbation of autoimmune diseases (3).

Side-effects of NUCs

  • OTOH, NUCs are given life-long though their long-term safety is still unclear.
  • Renal failure and bone loss are potential risk factors for long-term NUC Rx (3).
