NEJM:早期ART治疗可持续降低性伴侣生殖相关的的HIV-1感染

2016-07-19 MedSci MedSci原创

据来自HIV预防试验网络试验(HPTN)052试验的数据初步分析表明,抗逆转录病毒疗法(ART)可预防96%以上的HIV单阳配偶发生生殖相关的人类免疫缺陷病毒1型(HIV-1)感染。因而,所有HIV患者都应接受ART。该研究随访了5年多以评估ART预防HIV-1感染的耐久性。研究人员随机分配1763名HIV患者接受早期或延迟ART治疗。早期ART治疗的参与者中,886名参与者参与研究时开始治疗(C

据来自HIV预防试验网络试验(HPTN)052试验的数据初步分析表明,抗逆转录病毒疗法(ART)可预防96%以上的HIV单阳配偶发生生殖相关的人类免疫缺陷病毒1型(HIV-1)感染。因而,所有HIV患者都应接受ART。该研究随访了5年多以评估ART预防HIV-1感染的耐久性。

研究人员随机分配1763名HIV患者接受早期或延迟ART治疗。早期ART治疗的参与者中,886名参与者参与研究时开始治疗(CD4+细胞计数,350-550个细胞每立方毫米)。延迟ART治疗组参与者中,877名参与者在连续两次CD4+计数下降至250个细胞每立方毫米以下或出现获得性免疫缺陷综合征的表征时开始接受治疗。研究的主要终点是意向治疗分析中先前HIV-1阴性的伴侣诊断为生殖相关的HIV-1感染。

对所有研究对象随访10031人年,其伴侣随访8509人年。随访期间,共有78名HIV伴侣感染HIV-1感染(年发病率,0.9%;95%可信区间为,0.7 - 1.1),确定了72名(92%)伴侣传染的病毒连锁状态。这些感染患者中,46名(3名来自早期ART治疗组,43名来自延迟治疗组;发病率,0.5%;95% CI为0.4-0.7)为伴侣传染所致,26名(14名来自早期ART治疗组,12名来自延迟治疗组;发病率,0.3%;95% CI为0.2 - 0.4)感染与伴侣无关。与延迟ART治疗相比,早期ART治疗可降低93%伴侣感染HIV的风险(危险比,0.07;95%可信区间为0.02-0.22)。并没有发现接受ART治疗且病毒抑制稳定的HIV-1感染者其伴侣发生生殖相关的HIV感染。

总而言之,早期ART治疗可持续降低性伴侣生殖相关的的HIV-1感染。
