LANCET INFECT DIS:强化cART疗法治疗HIV感染疗效无优势

在原发HIV-1感染的早期进行联合抗逆转录病毒疗法(cART)治疗能够有效抑制HIV病毒的蓄积。因此,在最新一期The Lancet Infectious Diseases杂志上在线发表的一篇论文中,作者评价了与传统的三药联合cART疗法相比,增加了raltegravir与maraviroc的强化型的五药cART疗法对HIV DNA载量的控制效果。

在这项随机、开放、3期临床试验中,研究人员从全法国的多个医院募集患者。纳入标准为原发HIV-1感染(western blot检测HIV-1不完整,同时血浆可测出HIV RNA),出现任一症状,或CD4+细胞含量低于500 个/ μL。患者按1:1比例被随机分配至强化组和标准组,标准组给予3药cART治疗(每日服用1次替诺福韦酯300 g,恩曲他滨200 g, darunavir 800 g, ritonavir 100 g);强化组给予5药联合治疗(除标准组药物及剂量外增加每日服用2次raltegravir 400 mg,maraviroc 150 mg)。通过随机选择的可变置换组块生成的预设随机化名单进行分组。主要评估指标为治疗24个月时的平均每106外周血单核细胞(PBMC)中的HIV DNA拷贝中位数。在调整后的意向治疗人群中进行分析,即所有开始参与该治疗方案的患者。

结果显示,在2010年4月26日至2011年7月13日间,本试验共募集了110名患者,其中92例参与了随机化分组,90例参与了治疗(每组45例)。在治疗24个月内,标准组2例(4 %),强化组6例(13 %)终止了试验。在第24个月时,2组患者的HIV DNA载量接近(log10每106 PBMC的数据为强化组 2•35 [IQR 2•05–2•50];标准组2•25 [1•71–2•55];p=0.21)。强化组发生7人8次3-4级临床不良反应,标准组出现7人7次。共出现3例严重不良事件:标准组2例(胰腺炎与脂肪代谢障碍)且属于治疗相关,强化组1例(自杀企图),但与治疗不相关。

因此,研究人员得出结论,在24个月的治疗后,强化型的cART治疗方案在HIV血中含量指标上显示出其疗效并不优于标准cART方案。该研究结果对后续临床治疗HIV-1感染的方案制订有一定的指导作用。

Lancet Infect Dis:特鲁瓦达或可有效预防HIV感染

用于预防个体患高风险艾滋(AIDS)病毒感染的HIV治疗药片特鲁瓦达频频传来好消息,本周二,在澳大利亚墨尔本国际艾滋病大会上研究者们就讨论了HIV治疗药片特鲁瓦达的功效,研究人员表示,一系列的跟踪研究调查表明,HIV治疗药片的确具有明显的功效,但研究者并不鼓励进行风险性的性行为,如果风险个体偶尔错过服药的话该药物也可以维持有效的机制。 相关研究成果刊登于国际杂志Lancet&nb

Clin Infect Dis:HIV感染个体或患年龄相关疾病的风险较高

近日,一项来自约翰霍普金斯大学的研究称,相比未感染HIV的成年个体来讲,相同年龄段感染HIV的成年个体或患心脏病发作、肾衰及癌症的风险较高,相关研究发表于国际杂志Clinical Infectious Diseases上,本文研究或为HIV感染者的健康护理提供新的研究线索和依据。Keri N. Althoff教授表示,我们并没有找到确凿的证据证实,相比未感染HIV的成年人,癌症等疾病会在年轻的HI

Lancet:第二例被“治愈”艾滋病婴儿重现HIV

研究者10月2日在《柳叶刀》上发表报告表示,此前认为已经被抗逆转录病毒药物治愈的艾滋病毒(HIV)阳性婴儿,再次出现了HIV感染迹象。这名婴儿也是第二例接受抗逆转录病毒药物后再次出现感染迹象的病例。在此之前,还有在2013年到2014年间轰动全球的“密西西比婴儿(Mississippi baby)”。 研究小组在报告中指出,这名婴儿出生于2009年12月,他的母亲是HIV阳性。婴儿出生

Nature:新型抵御HIV感染的被动免疫疗法

近日,刊登在国际著名杂志Nature上的一篇研究论文中,来自美国国家过敏症和传染病研究所的研究人员通过研究开发了一种名为被动免疫法的新型技术,其可以通过静脉注射的方法将广谱中和HIV的抗体(bNAbs)注射入机体中帮助预防HIV的感染,这种新型技术可以保护猴类免于猴免疫缺陷病毒(SIV)的感染。为了使这种被动免疫的疗法成为针对人类的一种可行的HIV预防策略,科学家们试图去修饰bNAbs,使其每隔几

喝奶边吃药,新型载药系统助力儿童HIV感染者治疗

从上世纪HIV被发现以来,人们对HIV的恐惧已经达到了谈艾色变的程度。虽然随着医学的发展,人们已经在抗击艾滋病的工作中取得了极大的成就。但是,对于治疗HIV感染的儿童的研究方面仍然面临着很大的挑战。这其中一个重要原因就是儿童脆弱的机体很难承受抗病毒药物的冲击。 最近来自宾州州立大学的研究人员别出心裁的开发出了一种基于酪蛋白的载药系统,能够成功运输治疗艾滋病药物Ritonavir。 酪蛋白主要存

NEJM:替诺福韦预曝光不能降低非洲女性的HIV-1感染

育龄期女性需要有效的干预措施以防止HIV-1的感染。替诺福韦作为预防HIV-1感染的预曝光能否降低其女性感染率现仍未知,因此Jeanne M等人进行了一项随机、安慰剂对照试验。最新研究结果发表在2015-2-5 NEJM上。 研究者们在2009年9月——2011年6月期间从南非、乌干达和津巴布韦的15个地区筛选12320名符合以下纳入标准的女性:18-45岁非妊娠期、非哺乳期、近期有性交史且
