摘要

摘要: 目的探讨HBeAg阴性慢性乙型肝炎（CHB）患者在初次抗病毒治疗发生不完全应答后，采用联合或序贯方案的疗效及安全性差异，为临床实践提供证据支持。方法纳入2020年1月—2023年12月在中国人民解放军联勤保障部队第九八〇医院肝病科门诊就诊的117例符合不完全应答标准的HBeAg阴性CHB患者（抗病毒治疗1年HBV DNA≥20 IU/mL），根据临床实际，将患者分为联合组（原抗病毒药物联合第二种药物）和序贯组（停用原药换用新药）。主要疗效指标为联合或序贯治疗4、12、24、48周时的HBV DNA阴转率，次要疗效指标为各随访时间点患者ALT复常率及肾功能、心肌酶和血脂水平。符合正态分布的计量资料2组间比较采用成组t检验；计数资料2组间比较采用χ²检验和Fisher精确概率检验。结果 117例CHB患者中，联合组49例，序贯组68例。联合或序贯治疗24、48周，联合组HBV DNA阴转率显著高于序贯组（24周：95.92% vs 80.88%，χ²=5.761，P=0.016；48周：97.96% vs 86.76%，χ²=4.566，P=0.044），组间比较差异均有统计学意义。与序贯组相比，联合治疗对高病毒载量（HBV DNA≥10⁴IU/mL）患者的病毒抑制水平更显著（12周：73.33% vs 19.05%，χ²=10.609，P=0.002；24周：86.67% vs 47.62%，χ²=5.783，P=0.033）。在低病毒载量患者中，联合或序贯方案组间疗效无明显差异（P值均>0.05）。联合组4、12、24、48周随访点ALT复常率分别为65.31%、89.80%、81.63%和95.92%，序贯组分别为54.41%、89.71%、86.76%和94.12%，2组间比较，差异均无统计学意义（P值均>0.05）。联合和序贯治疗48周内，两组均未出现肾功能、心肌酶、血脂等相关指标异常。结论对于HBeAg阴性CHB初治不完全应答患者，联合治疗在高病毒载量亚组中显著优于序贯治疗，能更快实现病毒学抑制；而低病毒载量患者中两者疗效趋同。联合和序贯治疗总体安全性良好。

Abstract: Objective To investigate the efficacy and safety of combined versus sequential antiviral regimens in HBeAg-negative chronic hepatitis B （CHB） patients achieving incomplete virological response during initial antiviral therapy， and to provide evidence for clinical practice. Methods A total of 117 HBeAg-negative CHB patients who attended The 980^th Hospital of PLA Joint Logistics Support Force from January 2020 to December 2023 and met the criteria for incomplete virological response were enrolled， and according to the clinical treatment regimen， they were divided into combination group （the original antiviral agent combined with another type of drug） and sequential group （switching to a new drug）. The primary outcome measure was HBV DNA clearance rate at weeks 4， 12， 24， and 48 of combined or sequential therapy， and the secondary outcome measures were alanine aminotransferase （ALT） normalization rate， renal function， myocardial enzymes， and blood lipid profiles. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the chi-square test and the Fisher’s exact test were used for comparison of categorical data between two groups. Results Among the 117 CHB patients， there were 49 patients in the combination group and 68 patients in the sequential group. At weeks 24 and 48 of combined or sequential therapy， the combination group had a significantly higher HBV DNA clearance rate than the sequential group （week 24： 95.92% vs 80.88%， χ²=5.761， P=0.016； week 48： 97.96% vs 86.76%， χ²=4.566， P=0.044）. Compared with the sequential group， the combination group showed a significantly higher level of viral inhibition in patients with a high viral load （HBV DNA ≥10⁴ IU/mL）（week 12： 73.33% vs 19.05%， χ²=10.609， P=0.002； week 24： 86.67% vs 47.62%， χ²=5.783， P=0.033）. There was no significant difference in treatment outcome between the two groups among the patients with a low viral load （P>0.05）. The combination group had an ALT normalization rate of 65.31%， 89.80%， 81.63%， and 95.92%， respectively， at 4， 12， 24， and 48 weeks， while the sequential group had an ALT normalization rate of 54.41%， 89.71%， 86.76%， and 94.12%， respectively； there were no significant differences between the two groups （all P>0.05）. There were no abnormalities in renal function， myocardial enzymes， and blood lipids in either group within 48 weeks of combined or sequential therapy. Conclusion In HBeAg-negative CHB patients with incomplete virological response， combination therapy has significantly better efficacy than sequential therapy in the high viral load subgroup and can achieve virological suppression more rapidly， and the two regimens have similar efficacy in patients with a low viral load. Both combined and sequential therapies have a favorable safety profile.
