胎儿、产科和生殖基因组学 (FORgenomics)
研究概览
详细说明
鉴于社会向晚育转变(部分与职业发展的增加有关),女性越来越多地推迟生育,因此面临生物生育力下降、孕产妇发病率增加和不良围产期妊娠结局以及抗逆转录病毒药物使用增加的问题。 先兆子痫 (PE) 使 2% 的妊娠并发,并且是严重的孕产妇和围产期并发症的主要原因。 没有治愈方法,唯一公认有益的初级预防是低剂量阿司匹林。 寻找一种有效的方法来预测和预防接受 ART 的高龄产妇的胎盘功能障碍 (PD) 仍然是一个挑战。
研究人员认为,可以在临床前检测到这组孕妇的孕产妇和围产期并发症,并采取早期预防措施。
另一方面,在这组患者中建立差异化的基因组模式将允许在孕前和妊娠期间采取预防措施。 此外,FORgenomics 可用于外部验证 IVF/ovodon 后妊娠期 PE 和 IUGR 发展的预测模型。 我们的结果可能适用于大多数医疗机构,并对母胎健康具有重要意义。
该提议的理由和假设是:(1) 可以在临床前检测这组孕妇的母体和围产期并发症,并通过基于子宫动脉多普勒超声和抗血管生成因子 (sFlt-1/ PlGF 比率)在第 13、16、20 和 26 周时识别处于发生 PE 高风险的孕妇; (2) 13、16 和 20 周的形态学超声有助于建立早期检测先天性异常的标准化程序,以及 (3) 在这组患者中建立差异化的基因组模式将有助于在孕前和孕期采取预防措施。
