Copeptin fetal growth restriction

OBJECTIVE: To evaluate the combination of plasma activated endothelial microparticles (CD62e), serum Copeptin (CPP) and placental growth factor (PlGF) levels at 18-23 weeks of gestation for prediction of preeclampsia (PE) in primigravid women. METHODS: This was a nested case-control study from a prospective cohort of 1115 primigravid women attending antenatal care clinic. Plasma levels of CD62e and serum Copeptin, PlGF levels were measured by flow cytometry and ELISA, respectively...

Copeptin, a marker of arginine vasopressin (AVP) secretion, is elevated throughout human pregnancies complicated by preeclampsia (PE), and AVP infusion throughout gestation is sufficient to induce the major phenotypes of PE in mice. Thus, we hypothesized a role for AVP in the pathogenesis of PE. AVP infusion into pregnant C57BL/6J mice resulted in hypertension, renal glomerular endotheliosis, intrauterine growth restriction, decreased placental growth factor (PGF), altered placental morphology, placental oxidative stress, and placental gene expression consistent with human PE...

OBJECTIVE: Intrauterine-growth-restriction-(IUGR) is associated with chronic fetal stress, as well as a phase of enhanced fetal/early postnatal insulin sensitivity, followed by a later emergence of insulin resistance. We aimed to prospectively investigate concentrations of copeptin, a sensitive marker of stress and insulin resistance, in IUGR versus appropriate-for-gestational-age-(AGA) fetuses. METHODS: Cord blood copeptin concentrations were determined by ELISA in well-defined, non-distressed at birth, asymmetric IUGR (n = 30) and AGA (n = 20) full-term pregnancies...

Abstract Objective: The aim of this study was to compare maternal and fetal serum copeptin concentrations in pregnancies complicated by isolated fetal growth restriction (FGR), and uncomplicated pregnancies, and to investigate relationships between copeptin levels and clinical parameters. Methods: Maternal and fetal serum copeptin levels were measured in 21 women with pregnancies complicated by isolated FGR and 20 women with normal pregnancies (control group). Doppler assessment of the uterine and umbilical arteries was performed in each patient...

OBJECTIVE: To compare venous cord plasma concentrations of 4 vasoactive peptide precursors: carboxy-terminal proarginine vasopressin, CT-prondothelin (ET)-1, midregional proadrenomedullin, and MR-proatrial natriuretic peptide, between fetuses with intrauterine growth restriction and appropriate for gestational age controls. STUDY DESIGN: Matched-pair analysis of 12 fetuses with significant intrauterine growth restriction and 42 healthy appropriate for gestational age control fetuses...
