This meta-analysis evaluated the impact of peg-interferon (peg-IFN) therapy added to nucleos(t)ide analogue (NA) treatment in chronic hepatitis B patients. Among 581 participants, 8.6% achieved HBsAg loss at the end of follow-up, with significant declines in HBsAg levels observed. The study highlights the potential of peg-IFN to enhance treatment outcomes in this population.

Key findings

  • 8.6% of patients achieved HBsAg loss at end of follow-up.
  • In patients with SOT HBsAg ≥1000 IU/mL, 29.7% achieved HBsAg <1000 at 24 weeks.
  • At 48 weeks, 47.5% of patients with SOT HBsAg ≥1000 IU/mL reached HBsAg <1000.

Why it matters

Understanding the efficacy of peg-IFN in combination with NA therapy is crucial for optimizing treatment strategies in chronic hepatitis B, potentially leading to improved patient outcomes and enhanced chances of achieving a functional cure.
