BJOG:孕早期TG含量过高或过低均与后代畸形有关

2015-04-18 MedSci MedSci原创

孕妇血脂含量会对胎儿先天性畸形的发生发展产生影响。因此Nederlof M等人进行了一项基于社区的前瞻性队列研究以探究孕早期孕妇血脂含量是否与主要的非综合性的先天性畸形(MNCA)有关。

孕妇血脂含量会对胎儿先天性畸形的发生发展产生影响。因此Nederlof M等人进行了一项基于社区的前瞻性队列研究以探究孕早期孕妇血脂含量是否与主要的非综合性的先天性畸形(MNCA)有关。
该研究共纳入2003-2004年间3074名孕产妇和其后代。通过参与者没有禁食的血液样本(平均12.9周孕)检测TG、TC、FFA、ApoB、ApoA含量。根据医疗登记信息和问卷调查获得围生期结局MNCA。
研究结果显示整体MNCA流行率为2.2%(n=68),其中20名为心血管系统异常,25为肌肉和骨骼系统异常,余下23为其他异常。同时研究者发现,孕早期孕妇TG含量与MNCA的发生率有非线性的联系。孕妇TG含量过低或过高均会导致MNCA估计发生概率增加。
当TG含量为0.73 mmol/l (5%)、1.28 mmol/l (50%)、2.35 mmol/l (95%)时,其MNCA估计发生率分别对应:3.6%、2.1%、2.9%。并且亚组分析提示心血管先天性异常与TG含量呈U形联系。而没有发现其他脂质与MNCA的发生有相关性。
研究结果表明,孕早期异常的TG含量,无论是偏高还是偏低,均会导致后代MNCA风险增加。因此备孕期间和怀孕期间应该努力将之保持在正常水平。不过后期还需要更多的临床实践研究来重复该结果。
