Endothelial extracellular vesicles in kids with newly diagnosed high blood pressure

Official title: Endothelial Extracellular Vesicles as Biomarkers of Blood Pressure-Induced Endothelial Activation in Children With Newly Diagnosed Untreated Primary Hypertension

Run by Josip Juraj Strossmayer University of Osijek · NCT07728643 · Data updated 2026-11-12

This study tests whether levels of endothelial extracellular vesicles are different in children with new, untreated primary hypertension compared to normotensive children.

Is this trial a fit for you?

Likely a good fit

Children and adolescents aged 6-17 with either normotension or newly diagnosed, untreated primary hypertension who can consent/assent and comply with procedures.

Probably not a fit

Patients with secondary hypertension, prior antihypertensive treatment, significant congenital or cardiovascular disease, diabetes, kidney disease, autoimmune or inflammatory conditions, acute infection, malignancy, or inability to comply with procedures may not benefit from this study.

What this trial studies

This observational case-control study will measure circulating endothelial extracellular vesicles (EEVs) in children and adolescents aged 6 to 17, comparing those with newly diagnosed, untreated primary hypertension to normotensive peers. Researchers will examine how EEV levels relate to blood pressure measurements, microvascular function via laser Doppler flowmetry, and other markers of endothelial activation. The goal is to understand endothelial injury in pediatric hypertension and explore non-invasive biomarkers for early cardiovascular risk.

Why it matters

Potential benefit: If successful, findings could pave the way for non-invasive biomarker tests to identify children at higher cardiovascular risk due to hypertension.

How similar studies have gone: Prior research in adults and in smaller pediatric cohorts suggests endothelial extracellular vesicles reflect endothelial activation, but data in pediatric hypertension are limited and exploratory.
