AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children and teenagers aged 6-17 years. They either have normal blood pressure or newly diagnosed high blood pressure that has not been treated.

Age
6-17 years
Sex
Boys and girls can both join.
Disease stage
Normal blood pressure, or newly diagnosed primary high blood pressure that has not been treated before.
Earlier treatment
Must not have had blood pressure medicine before.

Main reasons for not taking part

  • Secondary high blood pressure
  • Heart disease present from birth, or other major heart or blood vessel disease
  • Diabetes, chronic kidney disease, autoimmune or long-term inflammatory disease, or cancer
  • Acute infection at the time of enrolment
  • Taking medicines known to affect the lining of the blood vessels

Original description
Childhood hypertension is associated with early endothelial dysfunction and an increased risk of future cardiovascular disease. Endothelial extracellular vesicles (EEVs) have emerged as promising biomarkers of endothelial activation; however, their role in pediatric hypertension remains poorly understood. This observational case-control study aims to compare circulating EEV concentrations between normotensive children and children with newly diagnosed, untreated primary hypertension. The study will also investigate the associations between EEV levels, blood pressure, microvascular endothelial function assessed by laser Doppler flowmetry, and circulating biomarkers of endothelial activation. The findings may improve understanding of endothelial injury in pediatric hypertension and support the development of non-invasive biomarkers for early cardiovascular risk assessment.Read full original descriptionShow less

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

Childhood hypertension is associated with early endothelial dysfunction and an increased risk of future cardiovascular disease. Endothelial extracellular vesicles (EEVs) have emerged as promising biomarkers of endothelial activation; however, their role in pediatric hypertension remains poorly understood. This observational case-control study aims to compare circulating EEV concentrations between normotensive children and children with newly diagnosed, untreated primary hypertension. The study will also investigate the associations between EEV levels, blood pressure, microvascular endothelial function assessed by laser Doppler flowmetry, and circulating biomarkers of endothelial activation. The findings may improve understanding of endothelial injury in pediatric hypertension and support the development of non-invasive biomarkers for early cardiovascular risk assessment.

Inclusion: Children and adolescents aged 6-17 years; Written informed consent from a parent or legal guardian and assent from the participant when appropriate; Normotensive status or newly diagnosed, previously untreated primary hypertension according to current pediatric hypertension guidelines; Ability to comply with study procedures.

Exclusion: Previous antihypertensive treatment; Use of medications known to affect endothelial function; Secondary hypertension; Congenital heart disease or other significant cardiovascular disease; Diabetes mellitus; Chronic kidney disease; Autoimmune or chronic inflammatory disease; Acute infection at the time of enrollment; Malignancy; Inability to comply with study procedures.
