Tenofovir disoproxyl fumarate (TDF) disoproxyl fumarate (TDF) has in vitro activity against herpes simplex virus type 2 (HSV-2) and reduced HSV-2 acquisition as preexposure prophylaxis. Whether TDF-containing antiretroviral therapy (ART) reduces HSV-2 acquisition is unknown.
Secondary analysis of AIDS Clinical Trials Group A5175, a randomized, open-label study of 3 ART regimens among 1571 participants.
HSV-2 serostatus was assessed at baseline, at study exit, and before a change in ART regimen.
Of 365 HSV-2-seronegative persons, 68 acquired HSV-2, with 24 receiving TDF-containing ART and 44 receiving ART without TDF (HSV-2 seroconversion incidence, 6.42 and 6.63 cases/100 person-years, respectively; hazard ratio, 0.89; 95% confidence interval, .55-1.44).
HSV-2 acquisition was not reduced in HIV-infected, HSV-2-uninfected persons during TDF-containing ART.
替诺福韦酯(TDF)对2型单纯疱疹病毒(HSV-2)具有体外活性,并且作为暴露前预防可降低HSV-2感染率。含TDF的抗逆转录病毒疗法(ART)是否能降低HSV-2感染率尚不清楚。
对艾滋病临床试验组A5175进行二次分析,这是一项针对1571名参与者的3种ART方案的随机、开放标签研究。
在基线、研究结束时以及ART方案改变之前评估HSV-2血清学状态。
在365名HSV-2血清阴性者中,68人感染了HSV-2,其中24人接受含TDF的ART治疗,44人接受不含TDF的ART治疗(HSV-2血清转换发生率分别为6.42例/100人年和6.63例/100人年;风险比为0.89;95%置信区间为0.55-1.44)。
在接受含TDF的ART治疗的HIV感染且HSV-2未感染的人群中,HSV-2感染率并未降低。
