摘要:

目的:探究孕前胰岛素水平(INS)与复发性流产(RSA)患者早产风险的相关性。方法:采用回顾性列队研究设计,依据妊娠结局将20201月至202112月期间在本院成功妊娠且活产的594RSA患者分为足月产组和早产组。测定患者孕前空腹、餐后30 min1 h2 h3 hINS0INS05INS1INS2INS3,分析INS水平与早产的相关性。结果:594RSA活产患者早产率8.25%。单因素回归分析显示,孕前血清INS0INS2水平与早产显著相关(P<0.05)。阈值效应分析显示,孕前INS0=8.41 U·mL-1INS2=61.18 U·mL-1均是区分RSA孕妇足月分娩和早产的拐点(P<0.05);多因素Logistic回归分析显示,RSA患者孕前INS0≥8.41 U·mL-1aOR=2.2595%CI1.09 4.63)、INS2≥61.18 U·mL-1aOR=2.3195% CI1.16 4.60)均是影响其早产的独立危险因素(P<0.05)。Logistic回归分析显示,RSA孕前INS0是影响妊娠期高血压和脐带畸形的危险因素,孕前INS2水平是影响孕妇妊娠期糖尿病、羊水量异常、脐带畸形的危险因素(P<0.05)。结论:RSA患者再次妊娠前INS0≥8.41 U·mL-1INS2≥61.18 U·mL-1是影响早产发生的独立危险因素,同时孕前INS0高分泌会增加妊娠期高血压和脐带畸形发生风险,INS2高分泌会增加患者妊娠期糖尿病、羊水量异常、脐带畸形发生风险,建议将孕前INS0INS2筛查纳入RSA患者早产风险评估体系。

Abstract:

Objective: To investigate the correlation between pre-pregnancy insulin INS levels and the risk of preterm birth in patients with recurrent abortion RSA.Methods: A retrospective cohort study design was used to divide 594 RSA patients with successful pregnancy and live birth in our hospital from January 2020 to December 2021 into term birth group and premature birth group according to pregnancy outcomes. INS0 INS05 INS1 INS2 and INS3 levels were measured before pregnancy on fasting 30 min 1 h 2 h and 3 h after meal. The correlation between INS level and preterm birth was analyzed.Results: The preterm birth rate of the 594 RSA patients was 8.25%. Univariate regression analysis showed that serum INS0 and INS2 levels before pregnancy were significantly correlated with preterm delivery P<0.05. Threshold effect analysis showed that pre-pregnancy INS0=8.41 U·mL-1 and INS2=61.18 U·mL-1 were the inflection points to distinguish full-term delivery and preterm delivery of RSA pregnant women P<0.05. Multivariate Logistic regression analysis showed that INS0≥8.41 U·mL-1 aOR=2.25 95%CI 1.09 4.63 and INS2≥61.18 U·mL-1 aOR=2.31 95%CI 1.16 4.60 were independent risk factors for preterm birth P<0.05. Logistic regression analysis showed that RSA pre-pregnancy INS0 was a risk factor for gestational hypertension and umbilical cord malformation while pre-pregnancy INS2 level was a risk factor for gestational diabetes amniotic fluid volume abnormality and umbilical cord malformation P<0.05.Conclusion: INS0≥8.41 U·mL-1 and INS2≥61.18 U·mL-1 before pregnancy are independent risk factors for preterm delivery in RSA patients. Meanwhile high INS0 secretion before pregnancy may increase the risk of pregnancy hypertension and umbilical cord malformation. High INS2 secretion can increase the risk of gestational diabetes mellitus abnormal amniotic fluid volume and abnormal umbilical cord. It is suggested that preconception INS0 and INS2 screening should be included in the risk assessment system of preterm delivery in RSA patients.
