摘要: 目的 观察应用艾米替诺福韦(TMF)和丙酚替诺福韦(TAF)挽救治疗经治的出现低病毒血症(LLV)的慢性乙型肝炎(CHB)患者的临床疗效。方法 2022年1月~2024年1月我院收治的既往经恩替卡韦(ETV)治疗至少12个月应答不完全的CHB患者68例,采用随机数字表法将患者分为观察组和对照组,每组34例,停止ETV治疗后分别转换为TMF治疗或TAF治疗,两组均持续治疗观察48w。使用超声肝脏瞬时弹性成像设备行肝硬度检测(LSM),采用电化学发光法检测血清HBV标志物,采用电化学发光法检测血清透明质酸(HA)、层黏连蛋白(LN)、Ⅳ型胶原(Ⅳ-C)和Ⅲ型前胶原(PCⅢ),采用荧光探针PCR法检测血清HBV DNA载量,使用贝克曼BX800全自动生化分析仪检测血生化指标。结果 在治疗48 w末,观察组LSM及血清HA、LN、Ⅳ-C和PCⅢ水平分别为(6.8±1.2)KPa、(171.2±25.9)ng/mL、(147.5±42.3)ng/mL、(174.3±46.3)ng/mL和(56.8±12.4)ng/mL,与对照组【分别(6.9±1.2)KPa、(175.2±34.6)ng/mL、(148.2±46.3)ng/mL、(175.4±42.1)ng/mL和(55.5±19.5)ng/mL】比,无显著性差异(P>0.05);观察组血清总胆红素、丙氨酸氨基转移和天冬氨酸氨基转移酶水平分别为(16.4±1.4)μmol/L、(40.3±4.8)U/L和(32.4±5.1)U/L,与对照组【分别为(17.3±1.2)μmol/L、(41.8±4.5)U/L和(36.9±4.9)U/L】比,差异无显著性统计学意义(P>0.05);两组血清HBV DNA载量和ALT水平均恢复正常,两组生化和病毒学应答率比较,无显著性差异(P>0.05)。结论 对于ETV经治的出现LLV的CHB患者,给予TAF或TMF挽救治疗均可获得较好的临床疗效,都获得了完全病毒学应答,其长期疗效还有待于继续观察。

Abstract: Objective The aim of this study was to investigate clinical efficacy of tenofovir amibufenamide (TMF) and tenofovir alafenamide fumarate (TAF) in rescue treatment of entecavir (ETV)-treated patients with chronic hepatitis B(CHB) and low-level viremia (LLV). Methods 68 patients with CHB were enrolled in our hospital between January 2022 and January 2024, the enrolled patients were all ETV-treated for at least 12 months, showing poor virological response with LLV and were randomly assigned to receive TMF or TAF for 48 weeks. Liver stiffness measurement (LSM) was evaluated by ultrasonic liver transient elastography, serum HBV markers, biochemical parameters and HBV DNA loads were routinely detected. Serum laminin(LN),collagen type Ⅳ(Ⅳ-C), precollagen-Ⅲ (PC-Ⅲ)and hyaluronic acid(HA)levels were assayed by ELISA. Results By end of 48 week treatment, LSM as well as serum HA, LN, Ⅳ-C and PCⅢ levels in TMF-treated patients were (6.8±1.2)KPa, (171.2±25.9)ng/mL, (147.5±42.3)ng/mL, (174.3±46.3)ng/mL and (56.8±12.4)ng/mL, all not significantly different as compared to [(6.9±1.2)KPa, (175.2±34.6)ng/mL, (148.2±46.3)ng/mL, (175.4±42.1)ng/mL and (55.5±19.5)ng/mL, respectively] in TAF-treated patients (P>0.05); serum bilirubin, ALT and AST levels in TMF-treated patients were (16.4±1.4)μmol/L, (40.3±4.8)U/L and (32.4±5.1)U/L, all not significantly different as compared to [(17.3±1.2)μmol/L, (41.8±4.5)U/L and (36.9±4.9)U/L, respectively] in TAF-treated patients (P>0.05); virological and biochemical response rates in the two groups were not significantly different as serum HBV DNA transferred to negative and serum ALT level returned to normal(P>0.05) in all patients. Conclusion As for patients with CHB and poor response to ETV treatment, rescue antiviral therapy with TMF or TAF is both satisfactory, with complete virological response, and the long-term efficacy should be followed-up in the future.
