Investigating the role of FGF23 in pregnancy-related hypertension

Expression of Endocrine Fibroblast Growth Factor 23 and Hypertensive Disorder Complicating Pregnancy

Observational First Affiliated Hospital, Sun Yat-Sen University · NCT03821922

This study is trying to see if the levels of a protein called FGF23 are linked to high blood pressure during pregnancy by looking at blood samples from pregnant women with and without hypertension.

What this trial studies

This observational study aims to explore the relationship between fibroblast growth factor 23 (FGF23) levels and hypertensive disorders during pregnancy. It involves enrolling 100 pregnant women diagnosed with hypertension and 200 control women with normal pregnancies, matched for maternal and gestational age. Blood samples will be collected during each trimester to measure serum FGF23 levels and analyze their correlation with various health parameters. The study utilizes statistical methods to assess differences and relationships among the collected data.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women with singleton pregnancies who are receiving regular antenatal care.

Not a fit: Patients with multiple pregnancies or those with pre-existing conditions such as hypertension or thyroid diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the mechanisms behind pregnancy-induced hypertension, potentially leading to better management and outcomes for affected mothers and infants.

How similar studies have performed: While the specific role of FGF23 in pregnancy-induced hypertension is not extensively studied, related research on vitamin D and endothelial function suggests potential avenues for success.
