3% and 14.4%, respectively. Cirrhosis was found in 14.2% of all patients, with a higher frequency in the LdT group (28.4%) than the other two groups (12.2% in the ETV group and 14.6% in the LVD group). The proportions of patients who completed 1, 2, and 3 years of treatment are summarized in Table 2. Overall, 96.6% of patients did not modify the initial NA treatment. The ETV group had the highest rate of treatment maintenance

throughout the 3 years of treatment (≥ 98.2%), whereas the rate dropped from 90.5% and 97.0% at year 1 to 77.8% and 87.2% at year 3 in the LVD and LdT group, respectively. Figure 2 5-Fluoracil in vitro shows that the time to treatment modification was significantly different among the three groups (P < 0.001). A total of 16.1% of our patients had treatment modification: 9.0% in the ETV group, 38.8% in the LdT group, and 54.2% in the LVD group during the 3 years of treatment (Table 3). The most common type of treatment modification in the ETV group was “discontinuation of the initial NA” (59.5%), while “switch to another NA” was the most common in the LVD (50.0%) and LdT (42.3%) groups. None of the seven patients in the ETV group switched to another NA because of a clinical reason. The reasons for www.selleckchem.com/products/r428.html treatment modification were mainly clinical (83.0%

overall), with the major reasons being “fulfilling stopping criteria” in the ETV group (40.5%) and “virological breakthrough (including drug resistance)” in the LVD (46.2%) and LdT (61.5%) groups. The overall rate of adherence (mean ± SD) remained stable

throughout the entire treatment period (year 1: 96.8% ± 15.4%, year 2: 96.8% ± 11.5%, and year 3: 97.5% ± 10.3%) (Table 4). Further statistical analysis was performed to compare the patients with adherence rate > 90% with those ≤ 90%. For the first 2 years of treatment, the ETV group has statistically significant higher proportion of patients with > 90% adherence 上海皓元 rate among the 3 treatment groups. The proportion of patients with adherence rate > 90% at year 3 was 90.8% in the ETV group, 83.9% in the LdT group, and 83.9% in the LVD group; however, there is no statistical significant difference among the treatment groups. A total of five patients had at least one serious adverse event during the treatment period, four in the ETV group, and one in the LVD group. However, none of these were related to the NA used. In this multicenter observational study, we found that among ETV, LVD, and LdT, ETV had the lowest likelihood of initial NA treatment modification in treatment- naïve CHB patients in Taiwan during the 3-year treatment period. Our patients with ETV treatment also demonstrated the best adherence compared with those with LVD or LdT treatment. In this study, most patients completed the 3-year treatment without any modification of the initial NA, suggesting a satisfactory control of HBV replication during the treatment period. At year 1 of treatment, the rates of treatment modification were similar among the three groups.
