NEJM:孕酮不能提高复发性流产女性的活产婴儿率

2015-11-26 崔倩 译 MedSci原创

孕酮是维持妊娠的关键。然而,无论是在怀孕的头三个月补充孕激素会增加与不明原因反复流产史妇女的出生率是不确定的。

黄体酮是用于维持妊娠所必需的。然而,在怀孕的前三个月补充黄体酮是否会增加不明原因的反复流产史孕妇的活产婴儿率,是不确定的。

研究人员进行了一项多中心、双盲、安慰剂对照、随机试验,探讨了孕激素治疗是否会增加具有不明原因的反复流产史女性的活产婴儿和新生儿生存率。研究人员随机分配在妊娠12周内(不迟于6周)的习惯性流产女性接受400mg微粉化孕酮或相应安慰剂,纳阴道,每天两次。主要成果是妊娠24周后活产情况。

总共有1568名女性被评定为合格,其中836名女性在1年内自然受孕,并自愿参加试验,她们被随机分配接受孕酮(404名女性)或安慰剂(432名女性)。主要成果的随访率为98.8%(836名女性中的826名)。在意向性治疗分析中,活产率分别为孕酮组65.8%(398名女性中的262名),安慰剂组为63.3%(428名女性中的271名)(相对比率,1.04;95%置信区间[Cl],0.94至1.15;比率的差异,2.5个百分点;95%Cl,-4.0至9.0)。不良事件的发生率没有显著组间差异。

在怀孕的前三个月孕激素治疗没有导致有不明原因的反复流产史的女性有显著提高的活产婴儿率。
