Objective:
The objective of the study was to examine the associations of maternal plasma levels of 25-hydroxyvitamin D [25(OH)D] with angiogenesis and endothelial dysfunction indicators: soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), intercellular adhesion molecule-1 (ICAM-1), vascular adhesion molecule-1 (VCAM-1), and risk of preeclampsia.
Study Design:
In this prospective cohort study (n = 697), maternal plasma 25(OH)D levels were measured at 12-18 and 24-26 weeks; sFlt-1, PlGF, ICAM-1, and VCAM-1 levels were measured at 24-26 weeks.
Results:
Maternal PlGF levels were significantly lower in women with 25(OH)D less than 50 nmol/L at 12-18 weeks (median, 449.5 vs 507.9 pg/mL, P = 0.04) and 24-26 weeks (median, 450.4 vs 522.5 pg/mL, P = 0.007). Both maternal 25(OH)D and PlGF levels were inversely associated with the risk of preeclampsia (both P < .05). However, based on a test of interaction, there was no evidence that the association between vitamin D and preeclampsia depended on the level of PlGF.
Conclusion:
Maternal vitamin D deficiency is associated with low PlGF levels and increased preeclampsia risk. However, our data do not support the hypothesis that the association between vitamin D deficiency and preeclampsia is mediated by impaired angiogenesis.
