| 摘 要： | 目的 探讨不同转换治疗策略对慢性乙型肝炎(CHB)经治发生低病毒血症(LLV)患者疗效 的影响。方法 本研究纳入197例ETV或TDF经治的发生LLV的CHB患者,被分为A组74例,B组63例和C组60例,分别给予ETV或TDF单药维持治疗或TAF替换治疗或ETV或TDF联合长效干扰素(peg-IFN)α-2b治疗观察48周。结果 在48周治疗末,C组完全病毒学应答率(CVR)和HBeAg阴转率分别为90.0%和41.7%,显著高于A组的16.2%和5.4%(P<0.05)或B组的66.7%和9.5%(P<0.05),B组和C组血清ALT复常率分别为20.6%和23.3%,显著高于A组的8.1%(P<0.05);C组血清HBsAg水平为3.0(2.8,3.4)lgIU/ml,显著低于A组【3.3(2.9,3.9)lgIU/ml,P<0.05】或B组【3.4(3.3,3.8)lgIU/ml,P<0.05】,血清HBeAg水平为0.1(-0.7,0.0)lgIU/ml,显著低于A组【0.6(-0.6,1.8) lgIU/ml,P<0.05】或B组【0.6(-0.3,1.8)lgIU/ml,P<0.05】,血清HBV DNA水平为1.3(1.3,1.3)lgIU/ml,显著低于A组【1.7(1.3,2.0)lgIU/ml,P<0.05】或B组【1.6(1.3,1.4)lgIU/ml,P<0.05】;B组和C组肝脏硬度检测(LSM)分别为6.4(4.3,8.4) kPa和6.2(4.2,7.7) kPa,显著低于A组【8.6(5.2,10.7) kPa,P<0.05】,三组血清ALT水平比较,无统计学差异(P＞0.05)。结论 对于核苷类经治出现LLV的CHB患者,为保险起见,换用TAF或继续核苷类联合peg-IFNα-2b治疗可进一步获得较好的病毒学应答率和一定程度的血清学应答率,其对长期疾病转归的影响还需要观察。

| Abstract: | Objective The aim of this study was to investigate the efficacy of switching from entecavir(ETV) or tenofovir(TDF) to other different antiviral therapy in ETV- or TDF-treated chronic hepatitis B (CHB) patients with low-level viraemia (LLV). Methods A total of 197 patients with CHB who had been treated with ETV or TDF were enrolled in this study and were divided into group A (n=74) continuing ETV or TDF treatment, group B( n=63) switching to TAF therapy and group C (n= 60) switching to ETV or TDF and peg-IFNα-2b combination therapy. The regimen lasted for (48±2) weeks. Results At the end of 48 week treatment, the complete virologic response and serum HBeAg negative rates in group C were 90.0% and 41.7%, significantly higher than 16.2% and 5.4%(P<0.05) in group A or 66.7% and 9.5%(P<0.05) in group B, and serum ALT normalization rates in group B and group C were 20.6% and 23.3%, significantly higher than 8.1%(P<0.05) in group A; serum HBsAg level in group C was 3.0(2.8, 3.4)lgIU/ml, significantly lower than [3.3(2.9, 3.9)lgIU/ml, P<0.05] in group A or [3.4(3.3, 3.8)lgIU/ml, P<0.05] in group B, serum HBeAg level was 0.1(-0.7, 0.0)lgIU/ml, significantly lower than [0.6(-0.6, 1.8) lgIU/ml, P<0.05] in group A or [0.6(-0.3, 1.8)lgIU/ml, P<0.05] in group B, and serum HBV DNA load was 1.3(1.3, 1.3)lgIU/ml, significantly lower than [1.7(1.3, 2.0)lgIU/ml, P<0.05] in group A or [1.6(1.3, 1.4)lgIU/ml, P<0.05] in group B; the LSMs in group B and group C were 6.4(4.3, 8.4) kPa and 6.2(4.2, 7.7) kPa, both significantly lower than [8.6(5.2, 10.7) kPa, P<0.05] in group A, and serum ALT levels in the three groups were not significantly different (P＞0.05). Conclusion The switch to TAF or combined with peg-IFNα-2b therapy in ETV- or TDF-treated patients with LLV might benefit for further virologic and even serologic response, and warrants clinical investigation. |
