Endothelial Biomarkers in Pregnancy: Endothelial Extracellular Vesicles and Hypertensive Disorders
Official title: Endothelial Extracellular Vesicles as Biomarkers of Blood Pressure-Induced Endothelial Activation in Pregnant Women With Hypertensive Disorders of Pregnancy
Run by Josip Juraj Strossmayer University of Osijek · NCT07728656 · Data updated 2026-11-12
This study tests whether endothelial extracellular vesicles in the blood differ between normotensive pregnant women and those with hypertensive disorders of pregnancy.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are pregnant women aged 18 or older with singleton pregnancies, either normotensive or diagnosed with gestational hypertension or preeclampsia, who can consent and comply with procedures.
✕Probably not a fit
Pregnant women without hypertensive disorders or who cannot complete the study procedures may not benefit from the biomarker insights.

What this trial studies
This observational case-control study compares circulating endothelial extracellular vesicles (EEVs) in pregnant women with hypertensive disorders to those with normal blood pressure. It also looks at how EEV levels relate to blood pressure, microvascular function measured by laser Doppler flowmetry, and other endothelial activation markers. The goal is to better understand endothelial injury in pregnancy and explore non-invasive biomarkers for early detection and monitoring. The study will help clarify the link between endothelial activation and hypertensive conditions during pregnancy.
Why it matters
Potential benefit: If successful, the findings could lead to new non-invasive biomarkers for early detection and monitoring of hypertensive disorders in pregnancy.
How similar studies have gone: Previous work has shown endothelial biomarkers can reflect vascular health, and this approach has been explored in pregnancy but remains investigational.
