Abstract


Background: The aim of this study was to assess the efficacy and safety of peginterferon α-2a (pegIFN) and nucleos(t)ide analogues (NA) treatments in patients with hepatitis B envelope antigen (HBeAg)-positive chronic hepatitis B (CHB) with mild acute exacerbation (AE).

Methods: Treatment-naive HBeAg-positive CHB patients with AE who received pegIFN or NA (entecavir (ETV) or telbivudine (LDT)) therapies were retrospectively selected. The HBeAg seroconversion rate, hepatitis B surface antigen (HBsAg) loss rate and the cost-effectiveness of different treatments were compared.

Results: A total of 63 patients with pegIFN therapy and 78 with NA (38 with ETV and 40 with LDT) therapy were included. The HBsAg loss rate was significantly higher in the pegIFN group when compared with the NA group (on week 96: 9/63 (14.29%) vs. 1/78 (1.28%), P = 0.005). No significant difference in hepatitis B virus (HBV) DNA negativity or the HBeAg/HBsAg seroconversion rate was found between ETV and LDT group. One year of pegIFN therapy resulted in 18.56 quality-adjusted life years (QALYs) per patient, and the incremental cost per additional QALY gained was $3,709.

Conclusions: PegIFN therapy is safe in HBeAg-positive CHB patients with mild AE, as it results in a higher HBsAg loss rate and longer QALYs than NA therapy.
