Summary. To assess the impact of sequential therapy with adefovir
dipivoxil (ADV) and pegylated interferon alfa-2a (PEG-IFN) on virological
(serum HBV-DNA) and serological (serum HBsAg) response in 20 consecutive
HBeAg-negative patients. Patients received ADV for 20 weeks, then ADV and
PEG-IFN for 4 weeks and lastly PEG-IFN for 44 weeks. Serum HBV-DNA and
HBsAg were assessed at baseline, during therapy (weeks 20, 44 and 68) and
follow-up (weeks 92 and 116). Sustained virological response (SVR) was
defined as serum HBV-DNA <10 000 copies/mL (partial) or <70 copies/mL
(complete) 24 weeks after stopping treatment. A serological response was
defined as a serum HBsAg decrease ≥1 log10IU/mL at the end of treatment.
Baseline median serum HBV-DNA and HBsAg levels were 7.6 log10copies/mL and
3.8 log10IU/mL, respectively. Ten patients (50%) achieved SVR, six of them
had partial response and four complete response. Four patients (20%)
achieved serological response. Complete SVRs showed a major and steep
decline in HBsAg level with a median decrease of 0.5, 1.6 and 2.0
log10IU/mL at treatment week 20, 44 and 68, respectively. Partial SVRs
showed a slight and slow decline in serum HBsAg level (0.1, 0.4, and 0.6
log IU/mL at weeks 20, 44 and 68, respectively). On-treatment serum HBsAg
decrease had a high accuracy to predict SVR (AUROC = 0.88). Our results
suggest that sequential therapy might be an interesting strategy for
HBeAg-negative patients. Serum HBsAg kinetics seem to be an accurate tool
to predict SVR. Large clinical trials are needed to explore this strategy
with more potent analogues. |
