Diabet Med:二甲双胍的神奇之处又添一笔 降低先兆子痫风险

2018-03-22 吴星 环球医学

018年2月,英国和美国科学家在《Diabet Med》发表了一项系统评价和Meta分析,对评估妊娠前或妊娠期服用二甲双胍的胰岛素抵抗高危女性的先兆子痫风险的研究进行了分析。

孕妇发生先兆子痫,有可能导致一尸两命的悲剧。胰岛素抵抗是先兆子痫的危险因素之一。在降低胰岛素抵抗高危女性的先兆子痫风险方面,降糖神药二甲双胍能否再次大显神威呢?

2018年2月,英国和美国科学家在《Diabet Med》发表了一项系统评价和Meta分析,对评估妊娠前或妊娠期服用二甲双胍的胰岛素抵抗高危女性的先兆子痫风险的研究进行了分析。

研究者对Medline、EMBASE、科学网和Scopus数据库进行检索,将考察妊娠前或妊娠期服用二甲双胍vs安慰剂/对照或胰岛素的随机对照试验和前瞻性观察性队列研究纳入到本Meta分析中。主要结局测量指标为每个治疗组中先兆子痫发病率。

总体来说,5项随机对照试验比较了二甲双胍(611例)和安慰剂/对照(609例),先兆子痫风险无差异。4项队列研究的Meta分析也显示两组没有显着作用。8项比较了二甲双胍(838例)和胰岛素(836例)的随机对照试验的Meta分析显示,二甲双胍组的先兆子痫风险降低

随机对照试验的二甲双胍vs胰岛素分析无异质性,而比较二甲双胍vs安慰剂/对照的研究异质性较高。大多数研究中,先兆子痫是次要结局。二甲双胍组从入组到分娩的平均增重增加较少。

在将孕妇随机分配到降糖治疗组的研究中,与胰岛素相比,二甲双胍与较低的妊娠期增重和较低的先兆子痫风险相关。

这是首个关注服用二甲双胍vs安慰剂/胰岛素的妊娠女性的先兆子痫发病率,并阐明胰岛素抵抗女性的潜在临床机制的系统评价和meta分析。在本系统评价中,研究者分析并评价了在合并胰岛素抵抗性疾病(如PCOS、肥胖、2型糖尿病和GDM)的妊娠女性中比较二甲双胍与安慰剂/对照或胰岛素治疗的前瞻性观察性临床研究和RCTs。这些女性发生妊娠并发症的风险较高,包括先兆子痫。研究者分别对队列研究和RCTs进行meta分析。研究者也进行了两项独立分析,比较二甲双胍vs安慰剂/对照和二甲双胍vs胰岛素。

虽然二甲双胍是一个老药,但就如阿司匹林一样,总不时给我们带来意外的惊喜,其身份也早已不再局限于降糖。现在发现,二甲双胍或有降低胰岛素抵抗高危女性先兆子痫风险的潜力。
