背景  该研究的目标是评估洛匹那韦–利托那韦双重治疗以及拉米夫定和洛匹那韦–利托那韦加上HIV-1病毒抑制的两个核苷(酸)的三联双治疗的非劣效性。

方法  在这项随机,开放标签,非劣效性试验中,研究人员从西班牙和法国医院的32 HIV单位招募了患者。符合条件的患者为感染HIV的成人(年龄≥18岁),HIV-1 RNA每毫升少于50个拷贝,至少6个月的洛匹那韦-利托那韦(每日两次)加拉米夫定或恩曲他滨和第二核苷的三重治疗,对这些药物没有阻力或病毒学失败现象,并且乙肝血清表面抗原不是阳性。各中心调查人员随机分配患者(1:1;四块大小;按抑制时间分层[<1年或> 1年],最低CD4细胞计数[<每微升100个细胞或>每微升100个细胞]。计算机生成的随机序列),以继续三重治疗或切换到双重治疗(每天两次口服洛匹那韦400毫克和口服利托100 mg,加口服拉米夫定每日一次300毫克)。主要终点是对治疗的反应,在48周对意向性治疗人群(所有随机患者)进行分析。非劣效性为12%。

结果  在2011年10月1日和2013年4月1日之间,研究人员随机分配250名参与者继续三重治疗(127[51%]例)或切换到双重治疗(123[49%]例)。在意向治疗人群中,三重治疗组的127例患者中的110(86.6%)例对治疗有反应,双重治疗组中123例中的108(87.8%)例对治疗有反应(差异-1.2%[95%Cl -9.6-7.3];p=0.92),符合标准的非劣效性。三重治疗组的严重不良事件发生8(7%)例,双重治疗组中发生5(4%)例(p=0.515),由于不良事件发生而停止研究药物的是三重治疗组中的4(3%)例,双重治疗组中的1例(1%)(p=0.223)。

结论  洛匹那韦-利托那韦双重治疗加上拉米夫定治疗具有非劣疗效,同样耐受三重治疗。

Lancet:抗病毒治疗是否可以减少HIV相关的结核病发病率?

背景:长期接受抗逆转录病毒疗法(ART)的艾滋病病毒感染者的结核病发病率是否仍高于背景人口率还不清楚。因此研究人员比较了在英格兰、威尔士和北爱尔兰的背景人口率接受ART治疗的人的结核病发病率。    方法:研究人员分析了国家结核病登记的艾滋病毒阳性患者。在HIV阳性人群中(2007-11),结核病发病率通过人种、接受ART的时间以及与背景率(2009年)比较进行分层。

PNAS:艾滋病毒的“隐形衣”

埃默里大学医学院,耶基斯国家灵长类动物研究中心和亚特兰大儿童卫生保健的病毒学家发现了一个有关艾滋病的关键问题,即艾滋病毒如何组装它的传染性隐形衣。 艾滋病毒的感染途径是从细胞到细胞的传播,因为病毒包膜蛋白需要合成为病毒颗粒,所以它们摆脱了受感染的细胞。医学博士Paul Spearman发现,包膜蛋白的一小部分位于HIV的尾巴上,是HIV病毒分为病毒颗粒必要的蛋白质。该研究结果发表在美国国家科学院
