本研究旨在描述明显糖尿病/妊娠糖尿病 (OD/GD) 女性与血糖正常女性相比,绒毛膜远端绒毛不成熟 (DVI) 的患病率,并分析 DVI 指数 (DVII) 与胎盘生长因子 (PlGF) 和可溶性 Fms 样酪氨酸激酶 1 (sFlt-1) 的关系。研究了三组;血糖正常 (n=21)、OD (n=17) 和 GD (n=20)。评估母体血液样本中 PlGF 和 sFlt-1 的血清水平。对所有受试者的足月胎盘采用免疫组织化学方法来评估 PlGF 和 sFlt-1 免疫染色的 DVII 和面积%。我们发现,血糖正常者的平均糖化血红蛋白 (HbA1c) 为 5.22 +/- 0.15,OD 组为 6.2 +/- 0.3,GD 组为 5.70 +/- 0.23,组间差异显着 (p=0.012)。与对照组(11.6 +/- 2.5;p=0.000)相比,DVII 的 OD(66.6 +/- 4.7)和 GD(72.4 +/- 4.5)显着更高。与 OD(166.6 +/- 22.4,p=0.000)和 GD(150.3 +/- 23.97,p=0.000)相比,健康女性的 PlGF 水平显着较低(86.6 +/- 14.5),并且与 OD(14.8 +/- 0.8)相比,她们胎盘表达的 PlGF 面积百分比显着更低(6.5 +/- 0.8)。 1.0,p=0.000)和 GD(18.8 +/- 1.3,p=0.000)。此外,与 OD(226.5 +/- 18.6,p=0.000)或 GD(197.2 +/- 16.8,p=0.000)相比,血糖正常女性的 sFlt-1 水平显着较低(108.9 +/- 12.1),并且与 OD 相比,她们胎盘表达的 sFlt-1 面积百分比显着较低(3.2 +/- 0.3) (15.4 +/- 1.7,p=0.000)和 GD(16.9 +/- 1.2,p=0.000)。 DVII 与以下两项要求之间存在显着相关性:3 组中 PlGF 和 sFlt-1 表达的血清水平和面积%。这项研究为评估正常和糖尿病胎盘中的 DVI 提供了新的评分,并提出了 PlGF 和 sFlt-1 在糖尿病妊娠中 DVI 调节中的作用。
This study aimed to describe the prevalence of chorionic distal villous immaturity (DVI) in overt diabetic/gestational diabetic (OD/GD) women compared with normoglycemic ones and to analyze the relation of DVI index (DVII) to placental growth factor (PlGF) and soluble Fms-like tyrosine kinase 1 (sFlt-1). Three groups were studied; normoglycemics (n=21), OD (n=17) and GD (n=20). Maternal blood samples were evaluated regarding serum levels of PlGF and sFlt-1. Immunohistochemical methodologies were employed in term placentae of all subjects to assess DVII and area% of PlGF and sFlt-1 immunostaining. We found that mean Hemoglobin A1c (HbA1c) is 5.22 +/- 0.15 in normoglycemics, 6.2 +/- 0.3 in OD, and 5.70 +/- 0.23 in GD with significant differences between groups (p=0.012). DVII was significantly higher in OD (66.6 +/- 4.7) and GD (72.4 +/- 4.5) compared to controls (11.6 +/- 2.5; p=0.000). Healthy women have significantly lower levels of PlGF (86.6 +/- 14.5) compared to OD (166.6 +/- 22.4, p=0.000) and GD (150.3 +/- 23.97, p=0.000) and their placentae expressed a significantly lower area% of PlGF (6.5 +/- 0.8) compared to OD (14.8 +/- 1.0, p=0.000) and GD (18.8 +/- 1.3, p=0.000). Also, normoglycemic women have significantly lower levels of sFlt-1 (108.9 +/- 12.1) compared to OD (226.5 +/- 18.6, p=0.000) or GD (197.2 +/- 16.8, p=0.000) and their placentae expressed a significantly lower area% of sFlt-1 (3.2 +/- 0.3) compared to OD (15.4 +/- 1.7, p=0.000) and GD (16.9 +/- 1.2, p=0.000). There was significant correlation between DVII and both requests to: serum level and area% of PlGF and sFlt-1 expression in the 3 groups. This study provided a new score for evaluating DVI in normal and diabetic placentae and suggested a role for PlGF and sFlt-1 in regulation of DVI in diabetic pregnancies.
