It is rare for a study to address immediate metabolic change in pre-eclamptic pregnancy. Our aim is to study the ante-partum and post-partum metabolic markers in pre-eclampsia. A total of 33 pre-eclamptic and 200 uncomplicated women with singleton pregnancies were recruited for the prospective research. Immediately ante-partum and 24-48 h postpartum venous blood samples were collected for the analysis of metabolic markers. In the pre-eclamptic group, the ante-partum fasting glucose, fasting insulin, triglyceride and free fatty acid levels were found to be higher than in the control group; however, ante-partum high-density lipoprotein level was lower. Interestingly, fasting glucose and insulin levels decreased by 24-48 h post-partum in both groups and no significant differences were found. Pre-eclamptic patients had lower post-partum high-density lipoprotein (P=0.02), higher triglyceride (P<0.001), higher free fatty acid (P=0.02) and higher apolipoprotein B levels (P=0.01) than the control group. Dyslipidemia lasts from ante-partum to immediate post-partum in pre-eclamptic women in the form of increased triglyceride, higher free fatty acid and decreased high-density lipoprotein levels. We speculate that women with dyslipidemia and higher baseline blood pressure tend to develop pre-eclampsia during pregnancy. Hence, the development of pre-eclampsia may be a 'marker' of possible future cardiovascular or metabolic disease.
这项研究很少针对子痫前期妊娠的即时代谢变化进行研究。我们的目的是研究子痫前期的产前和产后代谢标志物。共招募了 33 例子痫前期和 200 例单胎妊娠的非复杂妇女进行前瞻性研究。立即采集产前和产后 24-48 小时的静脉血样,用于分析代谢标志物。在子痫前期组中,产前空腹血糖、空腹胰岛素、甘油三酯和游离脂肪酸水平高于对照组;然而,产前高密度脂蛋白水平较低。有趣的是,两组的空腹血糖和胰岛素水平在产后 24-48 小时均降低,且无显著差异。与对照组相比,子痫前期患者产后高密度脂蛋白(P=0.02)、甘油三酯(P<0.001)、游离脂肪酸(P=0.02)和载脂蛋白 B 水平(P=0.01)更高。子痫前期妇女的血脂异常从产前持续到产后即刻,表现为甘油三酯增加、游离脂肪酸增加和高密度脂蛋白水平降低。我们推测,血脂异常和基线血压较高的妇女在怀孕期间更容易发生子痫前期。因此,子痫前期的发生可能是未来心血管或代谢疾病的“标志物”。
