PLoS One:奈韦拉平对孕妇血浆和母乳HIV-1 RNA的影响

2015-04-01 范伟译 MedSci原创

母乳传播的HIV-1的风险因素包括高血浆和乳汁病毒载量,低孕产妇CD4细胞计数和乳腺癌病理学如乳腺炎。 目的: 在分娩后采用单剂量奈韦拉平加上1周可比韦(齐多夫定/拉米夫定)或单剂量特鲁瓦达 (替诺福韦/恩曲他滨)治疗,确定奈韦拉平和隐性乳房炎对孕妇血浆和母乳 HIV-1 RNA的影响。 方法: 从2008年4月至2011年4月间产后1周,4周和6周感染HIV病毒的坦桑尼亚女性身上收集产妇血浆

母乳传播的HIV-1的风险因素包括高血浆和乳汁病毒载量,低孕产妇CD4细胞计数和乳腺癌病理学如乳腺炎。

目的: 在分娩后采用单剂量奈韦拉平加上1周可比韦(齐多夫定/拉米夫定)或单剂量特鲁瓦达 (替诺福韦/恩曲他滨)治疗,确定奈韦拉平和隐性乳房炎对孕妇血浆和母乳 HIV-1 RNA的影响。

方法: 从2008年4月至2011年4月间产后1周,4周和6周感染HIV病毒的坦桑尼亚女性身上收集产妇血浆和双边母乳样本。此外,血浆样本的收集来源于分娩时母亲和婴儿身上。

结果: 对273名女性的1212份母乳样本进行定量测定HIV-1 RNA。在分娩时,96%的女性和99%的婴儿检测到奈韦拉平的中位数(四分位差,IQR) 分别为1.5 μg/mL (0.75-2.20 μg/mL)和1.04 μg/mL(0.39-1.71 μg/mL),(P < 0.001)。在产后1周,93%和98%的女性在血浆和母乳中检测到奈韦拉平的中位数(IQR)分别为0.13 μg/mL(0.13-0.39 μg/mL)和0.22 μg/mL(0.13-0.34μg/mL)。产妇血浆和母乳HIV-1 RNA在所有参数上(R = 0.48,R = 0.7,R = 0.59;P = 0.01)相关联。67%的女性在一段时间6周内检测到隐性乳房炎,而在38%的母乳样本中也检测到。在1、4和6周,母乳样本与隐性乳房炎有明显较高的HIV-1 RNA (P < 0.05)。

结论: 短期抗逆转录病毒预防后,奈韦拉平在大多数婴儿脐带血样本中被检测到,通过第1周抑制血浆和母乳中HIV-1 RNA,孕妇的血浆和母乳的奈韦拉平的浓度也很高。
