OBJECTIVE
Determine the frequency of genital HIV-1 shedding in a large cohort of women on long-term suppressive antiretroviral therapy (ART) and its association with mucosal inflammation.
DESIGN
We measured levels of HIV-1 RNA and inflammation biomarkers in cervicovaginal lavage (CVL) from HIV-seropositive women enrolled in the Women's Interagency HIV Study (WIHS).
METHODS
HIV-1 was quantified (Abbott RealTime HIV-1 assay) from CVL samples of 332 WIHS participants with and without clinical evidence of genital inflammation at the time of CVL collection; participants had suppressed plasma viral load (PVL; limit of quantitation less than 20-4000 copies/ml depending on year of collection) for a median of 7.1 years [interquartile range (IQR) 3.4-9.8, Group 1] or for a median of 1.0 years (IQR = 0.5-1.0, Group 2). Twenty-two biomarkers of inflammation were measured in CVL to compare with clinical markers.
RESULTS
HIV-1 was detected in 47% of 38 pre-ART CVL samples (median 668 copies/ml) and detection in CVL was associated with higher pre-ART PVL. HIV-1 was detected in only 1 of 38 CVL samples from these women on suppressive antiretroviral therapy for 1 year. No HIV-1 RNA was detected in 294 CVL samples from a cross-sectional set of women with suppressed PVL for a median of 7 years. Clinical inflammation markers were correlated with inflammatory biomarkers in CVL specimens, although genital inflammation was not associated with measurable genital HIV-1 shedding in these WIHS participants on ART.
CONCLUSION
ART that suppresses HIV-1 in the plasma of women also prevents genital tract HIV-1 shedding, even in the presence of genital tract inflammation.
目的
在长期接受抑制性抗逆转录病毒疗法（ART）的大量女性队列中，确定生殖器 HIV-1 脱落的频率及其与黏膜炎症的关系。
设计
我们测量了艾滋病毒血清阳性的妇女参加妇女机构间艾滋病毒研究（WIHS）时从宫颈阴道灌洗（CVL）中 HIV-1 RNA 和炎症生物标志物的水平。
方法
从 332 名 WIHS 参与者的 CVL 样本中定量 HIV-1（Abbott RealTime HIV-1 测定），这些参与者在 CVL 采集时具有或不具有生殖器炎症的临床证据；参与者的血浆病毒载量（PVL）得到抑制（定量下限根据采集年份在 20-4000 拷贝/ml 之间），中位数为 7.1 年（四分位距 [IQR] 3.4-9.8，第 1 组）或中位数为 1.0 年（IQR=0.5-1.0，第 2 组）。为了与临床标志物进行比较，在 CVL 中测量了 22 种炎症生物标志物。
结果
在 38 个预 ART CVL 样本中的 47%（中位数为 668 拷贝/ml）中检测到 HIV-1，CVL 中的检测与较高的预 ART PVL 相关。在接受抑制性抗逆转录病毒治疗 1 年的这些女性的 38 个 CVL 样本中，仅在 1 个样本中检测到 HIV-1 RNA。在抑制性 PVL 中位数为 7 年的 294 个 CVL 样本中，未检测到 HIV-1 RNA。临床炎症标志物与 CVL 标本中的炎症生物标志物相关，尽管在这些接受 ART 的 WIHS 参与者中，生殖器炎症与可测量的生殖器 HIV-1 脱落无关。
结论
抑制女性血浆中 HIV-1 的 ART 也可防止生殖道 HIV-1 脱落，即使在存在生殖道炎症的情况下。
