Preeclampsia is a multifactorial disease characterized by high blood pressure and protein in the urine. In this study, we investigated the association of vitamin D binding protein (GC) and vitamin D receptor (VDR) gene polymorphism with the risk of developing preeclampsia.
25-hydroxyvitamin D was measured using High-performance Liquid Chromatography. Vitamin D binding protein and vitamin D receptor gene polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism.
The control subjects have significant higher level of 25-hydroxyvitamin D (33.5 ± 1.194 ng/mL) relative to patients (23.97 ± 1.604 ng/mL) (p < 0.05). Vitamin D receptor rs1544410 and rs2228570 dominant model (GA + AA; TC + CC) showed significant higher risk of developing Preeclampsia (OR = 4.11, 95% CI = 0.62-27.09, p < 0.01; OR = 3.58, 95%CI = 0.78-16.38, p < 0.001 respectively). Similarly, vitamin D binding protein rs7041 and rs4588, dominant model (TG + GG; CA + AA) showed higher risk of preeclampsia development compared to control people (OR = 1.69, 95%CI = 0.35-8.19, p < 0.05; OR = 1.06, 95%CI = 0.25-4.44, p < 0.05 respectively). AA genotype of rs4588 of GC gene was significantly associated with 25-hydroxyvitamin D level in serum relative to CC and CA (p < 0.05).
From our study, we can conclude that a low level of 25-hydroxyvitamin D, GC (rs1544410 and rs2228570), and VDR (rs4588 and rs7041) gene polymorphism is linked with an increased risk of developing preeclampsia.
子痫前期是一种以高血压和蛋白尿为特征的多因素疾病。在本研究中，我们调查了维生素D结合蛋白（GC）和维生素D受体（VDR）基因多态性与子痫前期发病风险的关联。
采用高效液相色谱法测定25-羟基维生素D。通过聚合酶链反应-限制性片段长度多态性确定维生素D结合蛋白和维生素D受体基因多态性。
与患者（23.97±1.604 ng/mL）相比，对照组受试者的25-羟基维生素D水平显著更高（33.5±1.194 ng/mL）（p<0.05）。维生素D受体rs1544410和rs2228570显性模型（GA+AA；TC+CC）显示子痫前期发病风险显著更高（OR=4.11，95%CI=0.62-27.09，p<0.01；OR=3.58，95%CI=0.78-16.38，p<0.001）。同样，维生素D结合蛋白rs7041和rs4588显性模型（TG+GG；CA+AA）与对照组相比，子痫前期发病风险更高（OR=1.69，95%CI=0.35-8.19，p<0.05；OR=1.06，95%CI=0.25-4.44，p<0.05）。相对于CC和CA，GC基因rs4588的AA基因型与血清25-羟基维生素D水平显著相关（p<0.05）。
从我们的研究中可以得出结论，低水平的25-羟基维生素D、GC（rs1544410和rs2228570）以及VDR（rs4588和rs7041）基因多态性与子痫前期发病风险增加有关。
