该研究来自中国复旦大学华山医院张文宏教授研究组。该回顾性研究旨在评估核苷类似物与聚乙二醇干扰素(PEG-IFN)序贯联合治疗既往长期NUCs治疗的慢乙肝患者的效果。

既往接受至少两年的NUCs治疗未实现HBeAg转阴或血清学转换的192例慢乙肝患者,接受48周的PEG-IFN序贯联合NUCs治疗或NUCs单药治疗。在上述患者中,83例患者采用联合治疗,109例患者采用NUCs单药治疗。所有患者进一步随访24周,治疗过程中和治疗后测定HBsAg水平。

与NUCs单药治疗相比,联合治疗组更多的患者实现完全病毒学应答(HBeAg转阴以及HBV DNA < 2000 IU /毫升)(60.24% vs 13.8%)以及HBsAg转阴(27.7% vs 0)。HBsAg基线水平为12周和24周时联合治疗组治疗反应较强的预测因素。

在HBsAg基线<1000IU/mL的患者中,100%的患者获得完全病毒学应答,91%的患者实现HBsAg转阴。在HBsAg基线≥1000 IU / mL的患者中,HBsAg在治疗12周时仍未下降的患者病毒学应答率显著较低。然而,第12周HBsAg下降超过0.5logIU/mL或第24周下降超过1.5logIU/mL的患者在仍有机会获得治疗的病毒学反应。

研究结果认为,NUCs和PEG-IFN序贯联合治疗可有效地获得较高的完全病毒学应答率,且既往长期NUCs治疗的患者发生HBsAg转阴。可以通过基线水平和治疗中HBsAg的动态变化模式来指导该治疗方案。

APT:ALT正常的慢乙肝患者肝纤维化比例仍较高

慢性乙型肝炎(CHB)可以导致肝硬化,肝癌和过早死亡。升高的丙氨酸转氨酶(ALT)水平≥标准上限(ULN)的上限是评估是否进行抗病毒治疗的主要决定因素,但是,单独ALT水平可能不是预测肝纤维化。但慢乙肝患者的ALT正常时,患者肝脏的纤维化情况究竟如何目前未有定论。来自斯坦福大学的研究人员对此进行了系统回顾与荟萃分析。 研究表明ALT ≤ 40 IU / L的慢乙肝患者,约五分之一可能有显

APASL 2014:乙肝的治疗终点及其实现方法

乙肝是危害我国人民健康的重要感染性疾病之一。2006年全国人群血清流行病学调查显示,1-59岁人群HBsAg携带率为7.18%,估算全国HBsAg携带者约为9300万人。乙肝的治疗终点是什么,如何实现治疗终点? 3月13日,台湾大学高嘉宏教授在APASL 2014会议上就乙肝治疗终点及其实现方法发表了自己的看法,现将主要内容编译如下。 1.治疗的最终目标不仅仅是降低HBV DN

DDS:乙肝易感人群疾病监测管理漏洞调查

目前临床实践对HBV感染监测和肝细胞癌监控并不完善,且对影响HBV监控情况的相关患者因素及医疗工作者因素也存在认识不足。因此,对HBV管理情况进行评估十分必要。 Burman等为评估HBV感染疾病监测模式、找到HBV管理指南遵守情况相关影响因素,对旧金山安全网医疗体系进行HBV管理实践情况、认知情况、态度及护理障碍因素等方面的调查,并回顾分析1727例HBV感染者病例记录,分析影响HBV感染监测

BMJ述评:中国防控乙肝重点在控制围产期病毒传播

乙型肝炎(乙肝)病毒感染在中国是最为严重传染病之一。尽管自1982年已有乙肝疫苗可以有效预防,但目前中国仍约有9300万乙肝病毒(HBV)携带者,每年用于治疗乙肝的费用约1000亿元人民币(约合106亿英镑,123亿欧元,160亿美元)。乙肝感染不仅增加了患肝癌和肝硬化的风险,而且乙肝患者还可能在求学、工作、人际关系及家庭中受到歧视。 中国政府于1992年提出新生儿接

CROH:乙肝再激活机制及预防

乙肝是一个全球性的健康问题,其流行有地域性差异。有报道称,约有20亿患者曾经感染过HBV,其中3.5-3.8亿是慢性携带者。在乙肝疫苗出现之前,20%的亚太人群及近1%的澳大利亚人HbsAg呈阳性。在美国及西欧的一些国家,由于新生儿疫苗广泛接种,HBV急性感染已明显下降,但是慢性感染仍十分流行。其原因包括HBV流行区来源的移民、围产期感染、日常接触和危险行为的传播等。 慢性乙肝的定义为Hbs

J Virol:乙肝治疗性疫苗研究在动物试验中成功

 1月13日,记者从中科院上海巴斯德研究所获悉,该所研究员蓝柯课题组在慢性乙肝治疗性疫苗研究中取得新突破。相关论文在线发表于《病毒学杂志》上。 在乙肝慢性感染过程中,针对病毒特异的效应细胞通常处于耐受或耗竭状态,主动免疫能够暂时性激活效应T细胞,但特异性免疫和免疫记忆反应很快恢复到病毒持续性感染形成的免疫耐受状态。因此,研究人员提出一种基于外源性抗原T细胞应答的免疫治疗概念,设计构建了一
