Background: Recent study showed serum soluble
programmed cell death protein 1 (sPD-1) is an important
immune-related marker for assessment of HBV activity.
However, it remains unclear whether serum sPD-1 levels
could predict HBV relapse or HBsAg loss after cessation of
nucleos(t)ide analogues (NAs) therapy The aims of this study
are to investigate (1) changes of serum sPD-1 levels during
and post-NA therapy. (2) role of sPD-1 on HBV relapse and
HBsAg loss after cessation of entecavir therapy Methods:
A total of 117 HBeAg-positive and 277 HBeAg-negative noncirrhotic
patients who had stopped entecavir treatment for at
least 12 months were recruited sPD-1 levels were check at
baseline, end of treatment and post-treatment 6 months All
patients fulfilled the stopping criteria proposed by of the Asian
Pacific Association for the Study of the Liver (APASL) 2012
guideline Results: The mean of sPD-1 levels at baseline, end
of treatment and post-treatment 6 months were 5 65±0 86,
4 69±0 69, 4 74±0 74 log pg/mL, respectively, in HBeAgpositive
patients and were 4 79±0 87, 4 15±0 79, 4 16±0 81
log pg/mL, respectively, in HBeAg-negative patients HBeAgpositive
patients had higher sPD-1 decline levels from end
of treatment to baseline than HBeAg-negative patients
(P=0 002) Patients without virological relapse had a higher
sPD-1 decline levels from end of treatment to post-treatment 6
months than those with virological relapse in HBeAg-positive
(0 03±0 24 vs -0 13±0 47 log pg/mL, P=0 023) and HBeAgnegative
patients (0 11±0 40 vs -0 07±0 42 log pg/mL,
P=0 001) The 6-year cumulative rates of virological relapse,
clinical relapse, and HBsAg loss were 58 5%, 49 8%, and
12 5%, respectively, in HBeAg-positive patients, and were
71 6%, 57 1%, and 31 6%, respectively, in HBeAg-negative
patients sPD-1 levels at post-treatment 6 months was an
independent factor of virological relapse in HBeAg-positive
and HBeAg-negative patients End-of-treatment HBsAg levels
was an independent factor of HBsAg loss in both groups. We
utilized a sPD-1 at post-treatment 6 months of 3000 pg/mL
and end-of-treatment HBsAg of 150 IU/mL as the optimal
values for predicting HBV relapse and HBsAg loss in HBeAgnegative
patients Of the patients who achieved sPD-1<3000
and ≥ 3000 pg/mL, the 5-year cumulative rates of virological
and clinical relapse, and HBsAg loss were 36 3% vs 82 4%,
24 7% vs 66 7%, and 52 1% vs 11 1%, respectively (all P <
0 001) Patients who achieved HBsAg<150 IU/mL and sPD-
1<3000 pg/mL, the 5-year cumulative rates of virological and
clinical relapse, and HBsAg loss were 27 6% , 21 6%, and
53 8%, respectively Conclusion: sPD-1 decline levels during
entecavir therapy was higher in HBeAg-positive patients
compared with HBeAg-negative patients sPD-1 levels at
post-treatment 6 months was a useful marker to predict HBV
relapse and HBsAg loss after discontinuation of entecavir
treatment. 作者: StephenW 时间: 2019-10-26 16:12
