Details and patient eligibility
About
This will be a prospective study conducted on women with a suspected/confirmed diagnosis of placental abruption. Maternal blood samples will be taken at various points during the peripartum period. A healthy group of women admitted for delivery will act as a matched control and will have their blood sampled at similar time points. The primary outcome variables will include the total number of micro-particles, the number of micro-particles from each cell line (platelet, placental, endothelial etc.), and protein markers (specifically; placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFLT-1), vascular endothelial growth factor (VEGF), soluble endoglin (sEng)). Secondary outcomes if will examine the correlation between placental micro-particles, biomarkers, and extent of placental abruption.
Full description
The purpose of this study is to determine how well maternal serum biomarkers and placental micro-particles (MP) correlate with PA. The sensitivity and specificity of these proteins will be analyzed to further increase our understanding of the pathological mechanisms involved in PA. The knowledge gained from this study has the potential to develop a diagnostic test for PA with the ability to improve outcomes for mother and baby through earlier diagnosis and targeted therapy.
