ABSTRACT BODY: Background and aims: To evaluate effectiveness and safety of Entecavir (ETV) in NA naïve patients with chronic hepatitis B and cirrhosis in a real life retrospective and prospective chinese cohort over 4 years.Methods:Six hundred and three consecutive NA naive patients with chronic hepatitis B and cirrhosis, including 507 prospective and 96 retrospective, were recruited in 10 clinical centers in China and treated with ETV 0.5 mg (including various generic and branded ETV)over 4 years. At baseline, median age was 39 years, 75.62% males, 70.48% HBeAg positive, 10.28% cirrhotics. Median HBV DNA was 6.93 log copies/ml (2.73-11.8) and ALT were 82.0 IU/L (5.2-4557.8). Liver function tests and HBV DNA, assessed by a sensitive assays, were performed non-interventional . Clinical data were collected if patients had medical records at 12, 24, 36, 48, 96, 144, 192 weeks post-treatment, according to follow-up period of the patients, and was analyzed using Statistically Package for Social Science 13.0 (SPSS, Inc., Chicago, IL). Continuous data with normal distribution was presented as mean (standard deviation), while abnormal distribution was presented as median.Results:The follow-up data of the patients undergoing ETV monotherapy was showed in Table 1, there are different varying patients population at every timepoint .The virological response rate (undetectable HBV DNA), progressively increased over time, from 22.78%(54/237) at month 6, to 31.47% (73/232)at year 1, 42.21% (111/263)at year 2, 52.8%(85/161) at year 3 and 45.31%(29/64) at years 4. The median period for patients achieved virological response was 12 months. The median level of serum HBV-DNA loads decreased from the baseline were 2.98 log copies/ml at month 6, 3.76 log copies/ml at year 1, 3.52 log copies/ml at year 2, 4.11 log copies/ml at year 3 and 5.20 log copies/ml at years 4. The biochemical response rates (ALT normalization) were 49.88% at month 6, 54.42% at year 1, 45.90% at year 2, 41.07% at year 3 and 57.97% at years 4. The rates of HBeAg seroconversion were 10.26% at month 6, 16.54% at year 1, 20.83% at year 2, 17.53% at year 3 and 24.39% at years 4, respectively. Conclusion:ETV suppressed HBV replication in most NA-naïve patients in real life practice over 4 years, with a favourable safety profile.
