抗逆转录病毒药物(ART)有可能通过降低血液和生殖器分泌物中的艾滋病毒浓度来预防艾滋病毒传播。事实上,具有有利假设的数学模型表明ART有可能阻止HIV的传播。基于生态和人口的研究以及涉及艾滋病毒不和谐异性恋夫妇的几项短期观察性研究的经验结果表明,抗逆转录病毒疗法可减少艾滋病毒传播。一项多国随机对照试验(NIH NPTN052)也在研究ART作为艾滋病毒不和谐夫妇预防的可靠性和持久性。后者和其他研究还考虑了性冒险行为,以及当ART用作预防时艾滋病毒耐药变异的传播。艾滋病毒的早期检测和治疗(“检测和治疗”)被视为一项重要的预防战略。在这篇文章中,我们回顾了支持使用ART预防HIV传播的数据,并严格审查了这一战略的公共卫生影响。
Antiretroviral agents (ART) have the potential to prevent HIV transmission by reducing the concentration of HIV in blood and genital secretions. Indeed, mathematical models with favorable assumptions suggest the potential of ART to stop the spread of HIV. Empirical results from ecological and population based studies, and several short term observational studies involving HIV discordant heterosexual couples suggest that ART reduces HIV transmission. A multinational randomized controlled trial (NIH NPTN052) also examining the reliability and durability of ART as prevention in HIV discordant couples is underway. The latter and other studies also consider sexual risk taking behavior, and transmission of HIV resistant variants when ART is used as prevention. Early HIV detection and treatment (“test and treat”) are being considered as an important prevention strategy. In this article, we review the data supporting the use of ART to prevent HIV transmission, and critically examine the public health implications of this strategy.
