2018年1月,发表在《Hum Reprod》上的一项系统评价和meta分析,考察了维生素D对经历辅助生殖治疗(ART)夫妻的怀孕和早期妊娠结局的作用。

研究问题:是否血清维生素D与经历ART女性的活产率相关?

答案:维生素D补充充足的ART女性活产率高于维生素D缺乏或补充不足的女性。

已知的内容:维生素缺乏与异常妊娠着床以及产科并发症风险增加相关,例如先兆子痫和新生儿生长受限。但是,维生素D对经历ART夫妻的怀孕和早期妊娠结局的作用了解甚少。

研究设计、规模和持续时间:关于11项已发表的队列研究(包括2700名女性)的一项系统评价和meta分析,调查了维生素D和ART结局之间的相关性。

受试者/材料、环境、方法:文献检索了报道维生素D和ART结局之间相关性的研究。检索的数据库包括MEDLINE、EMBASE、Cochrane对照试验的中心注册库和CINAHL。其中11项研究符合纳入标准。

主要结果和偶然因素:纳入的研究中有7项报道了活产(包括2026名患者)。与维生素D缺乏或补充不足的女性相比,维生素D含量补充充足的女性有更高的活产率(OR 1.33[1.08-1.65])。5项研究(包括1700名患者)发现维生素D含量高的女性比维生素D缺乏或补充不足的女性更可能获得阳性妊娠检测结局(OR 1.34[1.04-1.73])。纳入的11项研究(包括2700名患者)均报道了临床妊娠作为结局。维生素D含量高的女性更可能出现临床妊娠(OR 1.46[1.05-2.02])。6项研究(包括1635名患者)报道了流产与维生素D浓度的相关性。流产与维生素D浓度之间没有显着相关性(OR 1.12 [0.81-1.54])。所有纳入研究的Newcastle-Ottawa质量评估量表评分均较好。

警告的局限性原因:尽管在开展的系统评价中使用了严格的纳入标准,但纳入研究的人群特点和生育治疗方案存在异质性。

结果的启示:这项系统评价的结果表明,维生素D的状态与ART女性的生殖治疗结局存在相关性。并且结果表明,维生素D缺乏和不足可能是考虑ART治疗女性亟待解决的问题。应当考虑通过一项随机对照试验来验证该假设维生素D缺乏治疗获益的相关性。
