Abstract
Introduction

Loss of HBeAg and development of anti-HBe (seroconversion) is seen as a milestone and endpoint in the treatment of HBeAg-positive patients with chronic hepatitis B (CHB). Among patients treated with nucleos(t)ide analogs (NA), recurrent viremia is common after discontinuation of therapy. Entecavir (ETV) and tenofovir (TDF) are highly potent NA. The durability of virological response and HBeAg seroconversion in patients treated with these agents is not well studied.
Methods

We retrospectively studied the outcomes of 54 HBeAg-positive CHB patients who were treated with either ETV (n = 30) or TDF (23) or both (n = 1) that achieved virological response and underwent seroconversion and consolidation therapy before cessation of treatment.
Results

Only 4 (7 %) patients had sustained virological, serological, and biochemical remission. Thirteen patients (24 %) continued to have HBV DNA levels below 2000 IU/mL and normal alanine aminotransferase activity (ALT). Thirty-seven patients (69 %) developed HBV DNA >2000 IU/mL, with 20 having elevated ALT. Among these 37 patients, 23 (62 %) remained HBeAg negative/anti-HBe positive, 12 (32 %) became HBeAg positive, and 2 (5 %) were HBeAg and anti-HBe negative. Duration of consolidation therapy did not correlate with low versus high level of virological relapse.
Conclusions

Durability of HBeAg seroconversion associated with ETV or TDF was not superior to that reported in patients treated with less potent NA. Our results, aggregated with others, suggest HBeAg seroconversion should not be considered as a treatment endpoint for most HBeAg-positive patients treated with NA. Future updates of treatment guidelines should reconsider HBeAg seroconversion as an endpoint to therapy.

抽象的
简介

HBeAg消失和抗HBe(血清转换)的发展被视为一个里程碑,终点在HBeAg阳性慢性乙型肝炎(CHB)的治疗。在与核苷(酸)类似物(NA)治疗的患者,复发性病毒血症的治疗停药后常见。恩替卡韦(ETV)和替诺福韦(TDF)是高度有效的NA。病毒学应答和血清转换与这些药物治疗的患者的耐久性不充分的研究。
方法

我们回顾性研究了54例HBeAg阳性CHB患者谁是有两种ETV(N = 30)或TDF(23)处理或结果两个(N = 1)取得病毒学应答和戒烟治疗前进行血清学转换和巩固治疗。
结果

只有4(7%)的患者有持续病毒学,血清学和生物化学缓解。 13例(24%)仍然低于2000 IU / mL的HBV DNA水平和正常的谷丙转氨酶酶(ALT)。 37例(69%)出现HBV DNA> 2000 IU / mL时,用20 ALT升高。在这些37例,23(62%)仍然HBeAg阴性/抗HBe阳性,12(32%)成为HBeAg阳性,和2(5%)是HBeAg和抗-HBe阴性。巩固治疗时间并没有相关的病毒学复发的低与高的水平。
结论

与ETV或TDF相关血清转换的耐久性并不优于中报道的与较低效力NA治疗的患者。我们的研究结果,汇总与他人,建议HBeAg血清不应该被认为是与NA处理的最HBeAg阳性患者治疗终点。治疗指南未来的更新应重新考虑HBeAg血清学转换为一个端点治疗。
