Molecular analysis of the maternal-fetal interface in preeclampsia

Molecular Study of the Maternal-fetal Interface Prospectively to the Onset of Preeclampsia Using Single Cell Technology.

Observational Carlos Simon Foundation · NCT06232668

This study is trying to find specific markers in early pregnancy that could help identify women at risk for preeclampsia, using samples from those undergoing routine testing.

What this trial studies

This observational study aims to identify molecular markers and aberrant cell types at the maternal-fetal interface during early pregnancy in women at risk for preeclampsia. By collecting chorionic villi samples from pregnant women undergoing aneuploidy testing between 9 and 14 weeks of gestation, the study will utilize single-cell sequencing technology to analyze the molecular profiles associated with preeclampsia. The goal is to characterize the early development of preeclampsia and improve early detection and prevention strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women over the age of 18 who are between 9 and 14 weeks of gestation and are undergoing chorionic villus biopsy due to a risk of fetal chromosomal abnormalities.

Not a fit: Patients with multiple pregnancies or non-evolving pregnancies will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to early identification and intervention for women at risk of developing preeclampsia, potentially reducing maternal and fetal morbidity and mortality.

How similar studies have performed: While the approach of using single-cell sequencing for early detection of preeclampsia is innovative, similar studies have shown promise in identifying biomarkers for other obstetric complications.
