目前对早产的风险识别包括既往早产史、晚期流产史、宫颈管长度、胎儿纤连蛋白等。最近伦敦大学国王学院的一项最新研究显示了一种新的胎儿胎儿纤连蛋白测定可更好预测早产,且已经将其进一步发展成1-500ng/ml范围内的定量测定。这项发表在Obstetrics & Gynecology上的研究比较了孕18-21周和孕22-27周女性阴道液中新的胎儿纤连蛋白检测,以探究预测自发早产的最佳预测时期。不仅

目前对早产的风险识别包括既往早产史、晚期流产史、宫颈管长度、胎儿纤连蛋白等。最近伦敦大学国王学院的一项最新研究显示了一种新的胎儿纤连蛋白测定可更好预测早产,且已经将其进一步发展成1-500ng/ml范围内的定量测定。

这项发表在Obstetrics & Gynecology上的研究比较了孕18-21周和孕22-27周女性阴道液中新的胎儿纤连蛋白检测,以探究预测自发早产的最佳预测时期。不仅如此研究者还分别探究了10 ng/mL和200 ng/mL作为早产风险阈值能否更准确。

该研究共纳入898名高危孕妇,<34周分娩的女性中只有3.8%的胎儿纤连蛋白<10ng/mL(18-21周),与正常分娩的比例相似,22-27周检测中<10ng/mL的占2.9%。34周后分娩的女性中,不管是18-21周还是22-27周检测出>200ng/mL的女性比例相似(39%和43%)。作者认为18-21周或22-27周具有相似的预测价值,在用于研究的最低和最高阈值之间存在相对风险,生物标志物的定量测定联合宫颈管长度可以更好更准确的预测风险。不过这并不意味着18-21周的检测就可以取代22-27周的检测,还需要以后更多的研究以验证。

该研究也存在局限,比如有流产或早产史的孕妇恰好宫颈管短,显然会对该类人群进行干预,这就会影响自然的妊娠结局,减少预测能力。Andrew Shennan称:“研究目的是为了建立早期的早产风险预测,这样可以做到早干预,同时密切监测孕妇。但不仅仅是依靠传统的单一阈值,我们希望能在更早期识别出看似正常的早产风险孕妇,予以早期干预。”
