Relationship between the von Willebrand Factor Plasma Concentration and Ultrasonographic Doppler Findings in Pregnancies Complicated by Hypertensive Disorders: A Pilot Study

Gynecol Obstet Invest. 2018;83(3):252-258. doi: 10.1159/000488290. Epub 2018 Apr 5.

Abstract

Background/aims: Recent evidence suggests that impaired cytotrophoblast proliferation and migration are major factors responsible for the development of hypertension in pregnancy. Studies report that von Willebrand factor (vWf) is a specific endothelial damage plasma marker. The aim of this study was to evaluate the relationship between vWf maternal plasma concentration and maternal and fetal Doppler flow measurements in pregnancies complicated by hypertension. It may provide additional insight into the pathophysiology of pregnancy-related hypertension and show the potential method for disease prevention and therapy.

Methods: We created 3 study groups: pregnant women with chronic hypertension (n = 10), gestational hypertension (n = 18), preeclampsia (n = 21), and control (22 healthy pregnant women). Every woman underwent ultrasound Doppler flow measurements performed simultaneously with venous blood collection. The vWf plasma concentrations were assessed using the commercially available enzyme-linked immunosorbent assay kit.

Results: The preeclampsia group had significantly higher vWf plasma concentrations in those patients with ultrasonographic features of placental insufficiency than in those without these characteristics (638 ± 208 vs. 377 ± 74 ng/mL; p < 0.017).

Conclusion: Our results may confirm the arrangement and severity of endothelial damage in preeclamptic patients and may have identified those patients with a significantly higher risk of developing cardiovascular disease.

Keywords: Gestational hypertension; Placental insufficiency; Preeclampsia; von Willebrand factor.
