Alterations in the Plasma Proteome of Early-Onset Severe Preeclampsia

The hypothesis of this study is that many plasma proteins are altered in concentration and structure in preeclampsia and the elucidation of these alterations will add to the poorly understood pathophysiology of preeclampsia. In this study we will compare the maternal plasma proteomes of early-onset severe preeclampsia versus healthy controls, compare protein expression and quantification of the maternal plasma proteome at the time of diagnosis of EOS-preeclampsia to the plasma proteome of the same affected subject at 48 hours post delivery and we will verify the placental expression of differentially expressed or post-translationally modified proteins found in the plasma of women with EOS-preeclampsia.
