AbstractHepatitis B s antigen (HBsAg) loss is a rare event during nucleos(t)ide analogue (Nuc) therapy. Limited data suggest that stopping Nuc therapy may increase HBsAg loss rate in hepatitis B e antigen (HBeAg) negative patients. A large study was conducted to investigate this issue in more detail. Of the 1075 HBeAg-negative patients treated with Nuc for 156 (61-430) weeks, 6 showed HBsAg seroclearance during treatment at an estimated annual incidence of 0.15%. Of the patients who remained HBsAg seropositive, 691 (52.3 years old, 86% males, 44.6% cirrhosis) had stopped Nuc therapy by Asian-Pacific stopping rule and then were prospectively followed-up. Baseline and on treatment clinical and viral features, treatment duration, consolidation duration, time to undetectable HBV DNA, time to normal ALT, end of treatment (EOT) HBsAg and HBsAg log reduction were compared between patients with and without HBsAg seroclearance after EOT. During a median off-therapy follow-up period of 155 (2-614) weeks, HBsAg seroclearance was confirmed in 42 patients. The 6-year cumulative incidence was 13% with an estimated annual incidence of 1.78%. Cox regression analysis showed that shorter time to undetectable HBV DNA (<12wks), greater HBsAg reduction during therapy (>1 log10 ), lower EOT HBsAg level (<100 IU/mL), patients with sustained response and relapsers not retreated were factors for off-therapy HBsAg seroclearance.
CONCLUSION: The incidence of HBsAg seroclearance after stopping Nuc was much higher than that during therapy, and was highest in patients without virologic and clinical relapse. Patients with clinical relapse who remain untreated had 7.34 times higher incidence of HBsAg clearance than those received re-treatment, suggesting that transient untreated clinical relapse may drive sufficient immune control to functional cure.

抽象

在核苷(酸)类似物(Nuc)治疗期间,乙型肝炎抗原(HBsAg)丧失是罕见事件。有限的数据表明,停止Nuc疗法可能会增加乙型肝炎e抗原(HBeAg)阴性患者的HBsAg消失率。进行了一项大型研究来更详细地调查这个问题。在Nuc治疗156(61-430)周的1075例HBeAg阴性患者中,6例在治疗过程中出现HBsAg血清学清除,估计年发生率为0.15%。在HBsAg血清阳性的患者中,691例(52.3岁,86%男性,44.6%肝硬化)停止了亚太地区停止治疗的Nuc治疗,随后进行了前瞻性随访。比较在EOT后HBsAg血清清除率和HBsAg血清学清除率的基线和治疗的临床和病毒特征,治疗时间,巩固治疗时间,检测不到的HBV DNA的时间,ALT正常时间,治疗结束时间(EOT)。在155(2-614)周的中位治疗后随访期间,42例患者确诊为HBsAg血清学清除。 6年累计发病率为13%,预计年发病率为1.78%。 Cox回归分析显示,HBV DNA检测时间较短(<12wks),治疗期间HBsAg降低较多(> 1 log10),EOT HBsAg水平较低(<100 IU / mL),持续反应和复发未恢复的患者关闭治疗HBsAg血清学清除。
结论:

停用Nuc后HBsAg血清学清除的发生率远远高于治疗期间,无病毒学和临床复发的患者中HBsAg血清清除率最高。未经治疗的临床复发患者HBsAg清除发生率比接受再治疗的患者高7.34倍,提示短暂的未经治疗的临床复发可能导致足够的免疫控制功能治愈。本文受版权保护。版权所有。

Nuc抑制免疫系统?

不是.
没有或几乎没有hbvdna(Nuc抑制生产), 没有刺激免疫系统. 停止用药, 有hbvdna生产, 有刺激免疫系统.

嗯,这个观点我相信;因为在我的病例中得到验证; 当时使用NAs从135大三阳抗病毒到15阳,E抗体迟迟不出来,我就征求医生的意见停药啦,不到半年,E抗体出来了;
但同时带来的是ALT和HBV DNA的上升啊!

这个研究适应症应该是:
1. 治疗期间HBsAg降低较多(> 1 log10),准备停药时 HBsAg水平较低(<100 IU / mL)
2. HBV DNA检测不到和ALT正常超过6个月; 没有肝硬化和纤维化的肝损;
3. 个人的免疫力较强,如治疗前ALT升高,最好年龄<35;
同时,停药后初期建议每隔一个月检测ALT和HBV DNA,如异常参考防治指南恢复用药;

小三NUC治疗:
1. 台湾研究人员相信停止治疗合适的病人.
2. 停止治疗,有些病人会降低HbsAg,甚至可能会清除HBsAg。
3. 吉利德(Gilead)进行了临床试验来测试这个,没有明确的结论.

嗯,还是待解决的问题;
这个可能和个人的病史相关;也可能和HBV基因型相关,毕竟东亚地区B和C居多,欧美以A和D据多;
