Lancet Infect Dis:病毒性肝炎的筛查对HIV患者至关重要 (2010-2012年 中国免费抗病毒治疗项目)

2014-11-11 MedSci译 MedSci原创

肝炎相关性肝脏疾病是引起进行联合抗病毒治疗的HIV感染者或免疫缺陷综合征(AIDS)患者发病与死亡的一个主要原因。这一研究主要分析了乙型肝炎病毒(HBV)和丙型肝炎病毒(HCV)合并感染对中国HIV感染者预后的影响。我们利用2010-2011年期间中国免费抗病毒治疗项目中的数据进行了一个全国性的回顾性观察性队列研究。对大于18岁,刚开始接受标准抗病毒治疗,而且已经检测出HBV和HCV阳性的病人进行

肝炎相关性肝脏疾病是引起进行联合抗病毒治疗的HIV感染者或免疫缺陷综合征(AIDS)患者发病与死亡的一个主要原因。这一研究主要分析了乙型肝炎病毒(HBV)和丙型肝炎病毒(HCV)合并感染对中国HIV感染者预后的影响。

我们利用2010-2011年期间中国免费抗病毒治疗项目中的数据进行了一个全国性的回顾性观察性队列研究。对大于18岁,刚开始接受标准抗病毒治疗,而且已经检测出HBV和HCV阳性的病人进行随访,随访时间一直持续到2012年12月31日。我们运用Kaplan-Meier分析和Cox比例风险模型来评估存活率,用逻辑回归模型评估病毒失败率,免疫应答和护理维持率。

该项目中有33861名患者达到研究的合格标准。2958(8.7%)名参与者为HBV联合感染,6149(18.2%)名为HCV联合感染,1114名参与者(3.3%)三种感染并存。三重感染者(校正危险比1.90,95%CI 1.53--2.37)与HCV联合感染者(1.46,1.25--1.70)的全因死亡率高过HIV单独感染者。但在HBV联合感染的病人(1.06,0.89-1.26)中未发现这种情况。

另外,三重感染的患者比HIV单独感染的患者更容易发生抗病毒治疗失效(校正比值比【OR】1.26,95% CI 1.02-1.56)。然而在HBV(0.93,0.80—1.10)或HCV(1.10, 0.97—1.26)联合感染的病人中这种区别并不显著。研究没有发现以上任何一种联合感染对接受治疗1年后机体的CD4细胞数量有明显的影响。三重感染(OR1.37, 95% CI 1.16—1.62)及HCV联合感染(1.30, 1.17—1.45)的参与者失去随访的情况比HIV单独感染者更多见。在HBV联合感染(0.93, 0.82—1.05)的参与者中则没有这种情况出现。

研究表明,对已经诊断HIV阳性的个体进行病毒性肝炎的筛查至关重要。研究结果提示我们需要把对病毒性肝炎的有效管理纳入HIV治疗过程中。其中包括对三重感染、乙肝或丙肝病毒感染的有效治疗和对HBV阴性的HIV感染者进行乙肝疫苗接种,以降低中国乙肝高发地区HIV感染者的发病率和死亡率。肝炎联合感染对HIV疾病进展的影响还需要长期的数据来阐明。

HIV发现者谈艾滋研究进展

一年一度的林道诺贝尔奖得主大会,对于与会的年轻人来说绝对是足以改变一生的宝贵经历。本期Nature杂志以“Medical Research Masterclass”为题,推出了2014林道诺贝尔奖得主大会专题。该专题记录了多位诺贝尔奖得主与青年学者的直接交流。 法国巴斯德研究所的弗朗索瓦丝·巴尔-西诺西(Françoise Barré-Sinoussi)因为发现H

J Virol:线粒体蛋白TSPO抑制HIV囊膜蛋白合成

中国农业科学院哈尔滨兽医研究所郑永辉研究团队近日在国际病毒学权威期刊上发表了有关抑制艾滋病病毒囊膜蛋白合成的新途径的论文,为抗艾滋病疫苗及药物研制提供了新思路。郑永辉研究团队的研究结果能够为解释艾滋病病毒囊膜蛋白不能高效表达机制提供线索,而且阐明了一种新型的抗病毒机制。艾滋病疫苗的研制是一个世界性难题,至今仍没有成功。其难点之一就是艾滋病病毒的囊膜蛋白在哺乳动物细胞中很难得到高效表达。早在上个世纪

JAIDS:HIV感染者新希望,抗逆转录病毒治疗

近日旧金山加州大学新临床研究显示,与那些不使用兴奋剂的感染艾滋病毒的人相比,341名使用冰毒和可卡因的感染艾滋病毒的人通过抗逆转录病毒的方法治疗初步见效。 “艾滋病患者用抗逆转录病毒疗法常常遇到困难,部分原因由于医疗服务提供者的担忧,他们不能准确把握药物定向。来自本研究的发现表明,许多兴奋剂使用者能够准确把握抗逆转录病毒治疗方法,这样足以避免引起消极的临床后果。抗逆转录病毒疗法能引起一些较好

Genes Dev:美研究发现艾滋病治疗新靶点

HIV就像一条沉睡的巨龙,可以潜伏在一个人的细胞内很多年,规避治疗,在晚些时候才会醒来和发作,快速复制自我并破坏免疫系统。 最近,美国索尔克研究所的科学家们,发现了一种新蛋白,可参与活跃的HIV复制,相关研究结果发表最近的Genes & Development 杂志(2014年最新影响因子12.639)。这个新蛋白,称为Ssu72,是用来将HIV-1
