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. Results: Maternal serum copeptin levels were significantly higher in women with isolated FGR compared to controls (p = 0.042). In addition, maternal copeptin levels were inversely correlated with the uterine artery pulsatility and resistance indices and positively correlated with neonatal birth weight. Umbilical vein copeptin levels were significantly increased in neonates with adverse outcomes (p = 0.001). Conclusions: Increased maternal copeptin concentration may reflect a response to stress, thus serving as a compensatory mechanism in pregnancies complicated by FGR.en10.3109/14767058.2014.951622info:eu-repo/semantics/closedAccessCopeptinDoppler velocimetryfetal growth restrictionneonatal outcomepregnancyArticle281112781284WOS:000360436500006Q2Q3
