摘　　要：目的探讨恩替卡韦(ETV)与替诺福韦酯(TDF)对于高病毒载量初治患者的疗效及应答不佳的处理方案。方法选取2016年6月—2021年7月广西医科大学第一附属医院感染性疾病科慢性乙型肝炎(CHB)患者抗病毒治疗队列中符合入组条件的患者165例。入组患者为基线HBV DNA>6 lg拷贝/mL,使用ETV或TDF满48周的CHB初治患者,并采用荧光定量PCR法检测HBV DNA。统计48周治疗的病毒学应答率;Logistic回归分析影响48周HBV DNA<500拷贝/mL和<100拷贝/mL应答的因素;分层分析比较48周后不同年龄、性别、基线HBV DNA、ALT、一线用药种类、HBeAg状态情况下HBV DNA<500拷贝/mL和<100拷贝/mL的应答率。非正态分布的计量资料2组间比较采用Mann-Whitney U检验,计数资料组间比较采用χ^(2)检验或Fisher确切概率法,多因素分析采用二分类logistic回归模型分析。结果48周治疗后85.5%(141/165)的患者HBV DNA<500拷贝/mL,66.1%(109/165)的患者HBV DNA<100拷贝/mL,ETV与TDF两组间疗效差异无统计学意义。多因素logistic回归分析显示,性别、基线HBV DNA、基线ALT、基线HBeAg是获得完全病毒学应答的影响因素(OR值分别为2.793、0.369、4.556、0.120,95%CI分别为1.197~6.517、0.142~0.959、1.770~11.732、0.033~0.429,P值均<0.05)。基线ALT正常(≤40 U/L)的患者,48周治疗后75.6%(34/45)的患者HBV DNA<500拷贝/mL,53.3%(24/45)的患者HBV DNA<100拷贝/mL,ETV组与TDF组疗效差异无统计学意义。基线ALT异常(>40 U/L)的患者,48周治疗后89.2%(107/120)的患者HBV DNA<500拷贝/mL,TDF组高于ETV组(96.1%vs 84.1%,χ^(2)=4.386,P=0.036);70.8%(85/120)的患者HBV DNA<100拷贝/mL,TDF组与ETV组(78.4%vs 65.2%)相比,差异无统计学意义。基线ALT正常组与异常组年龄≤30岁的患者HBV DNA<100拷贝/mL应答率与年龄>30岁的患者相比(77.8%vs 47.2%,85.2%vs 66.7%),差异均无统计学意义。治疗48周后未获得完全病毒学应答即HBV DNA≥100拷贝/mL的患者,接受原方案延长治�Objective To investigate the efficacy of entecavir(ETV)versus tenofovir disoproxil fumarate(TDF)and the treatment measures for poor response in previously untreated chronic hepatitis B(CHB)patients with high viral load.Methods A total of 165 CHB patients who received antiviral therapy and met the inclusion criteria in Department of Infectious Diseases,The First Affiliated Hospital of Guangxi Medical University,from June 2016 to July 2021 were enrolled.The patients enrolled had a baseline HBV DNA level of>6lg copies/ml and were previously untreated CHB patients who had used ETV or TDF for 48 weeks,and quantitative real-time PCR was used to measure HBV DNA.Virologic response rate was calculated after 48 weeks of treatment;a logistic regression analysis was used to investigate the influencing factors for the response of HBV DNA<500 copies/mL and HBV DNA<100 copies/mL at 48 weeks;a stratified analysis was performed to compare the virologic response rate of HBV DNA<500 copies/ml and HBV DNA<100 copies/ml after 48 weeks between the patients with different ages,sexes,baseline HBV DNA levels,baseline alanine aminotransferase(ALT)levels,types of first-line medication,and HBeAg statuses.The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups,the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups,and the binary logistic regression model was used for multivariate analysis.Results After 48 weeks of treatment,85.5%(141/165)of the patients achieved an HBV DNA load of<500 copies/mL,and 66.1%(109/165)of the patients achieved an HBV DNA load of<100 copies/mL,with no significant difference in treatment outcome between the ETV group and the TDF group.The multivariate logistic regression analysis showed that sex(OR=2.793,95%CI:1.197-6.517),baseline HBV DNA(OR=0.369,95%CI:0.142-0.959),baseline ALT(OR=4.556,95%CI:1.770-11.732),and baseline HBeAg(OR=0.120,95%CI:0.033-0.429)were influencing factors for complete virologic respon
