Comparing microvesicles in pregnant women with and without pre-eclampsia

Study of Microvesicles in Pre-eclampsia

Not applicable Interventional University Hospital, Bordeaux · NCT05675969

This study is testing if the tiny particles in the blood of pregnant women can help tell the difference between those with severe pre-eclampsia and those without it.

What this trial studies

This study aims to analyze the concentration of microvesicles in the blood of pregnant women diagnosed with severe pre-eclampsia compared to those without the condition. Microvesicles are membrane fragments released by cells that may serve as biomarkers for various conditions, including pre-eclampsia. The research will utilize advanced techniques such as cryo-electron microscopy and flow cytometry to characterize and quantify these microvesicles. The goal is to better understand the role of microvesicles in pre-eclampsia and their potential as indicators of maternal health during pregnancy.

Who should consider this trial

Good fit: Ideal candidates include pregnant women aged 18 and older, between 23 and 31+6 weeks of gestation, with either a diagnosis of severe pre-eclampsia or those hospitalized for isolated threat of preterm delivery without inflammation.

Not a fit: Patients who are unable to provide informed consent or those under legal protection may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic tools for early detection of pre-eclampsia, enhancing maternal and fetal health outcomes.

How similar studies have performed: Previous studies have indicated the potential of microvesicles as biomarkers in pre-eclampsia, suggesting that this approach may yield valuable insights.
