Examining blood-derived vesicles in women with placenta previa and accreta spectrum

Shedding of Syncytiotrophoblast-derived Extracellular Vesicles is Increased in Placenta Previa and Accreta Spectrum: a Case-control Study.

NA · Fondazione Policlinico Universitario Agostino Gemelli IRCCS · NCT06867874

This study is trying to see if the levels of certain tiny particles in the blood can help us understand placenta previa and placenta accreta in women compared to healthy pregnancies.

What this trial studies

This case-control study aims to quantify the levels of syncytiotrophoblast-derived extracellular vesicles (STBEVs) in the maternal blood of women diagnosed with placenta previa and placenta accreta spectrum. It compares these levels to those in healthy pregnant women with normal placentation. Additionally, the study seeks to characterize the multi-omics profiling of the STBEVs cargo, including proteins, genes, and transcripts, to better understand their role in these conditions.

Who should consider this trial

Good fit: Ideal candidates include pregnant women diagnosed with placenta previa and accreta spectrum, as well as healthy pregnant women over 18 years old.

Not a fit: Patients under 18 years, those with twin pregnancies, chronic infections, cancers, or who cannot provide written consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and therapeutic strategies for managing placenta previa and accreta spectrum.

How similar studies have performed: While the approach of analyzing extracellular vesicles is gaining traction, the specific focus on STBEVs in the context of placenta previa and accreta spectrum is relatively novel.
