Identification of patients at risk for preeclampsia with the use of uterine artery Doppler velocimetry and copeptin

Purpose: To investigate the relationship between maternal copeptin levels and uterine artery Doppler examination and progress of preeclampsia. Materials and methods: A cross-sectional study was designed with women those were screened at 20+0 - 24+ 6 weeks' gestation between May 2014 and August 2014. The obstetric records of all normotensive women were examined. Uterine artery Doppler velocimetry results and serum copeptin levels were measured. The patients were divided into two groups according to normal (n = 67) and abnormal uterine artery Doppler (n = 21) findings. Results: Maternal age was significantly lower in group 1 (n = 21, 23.9%) than in group 2 (n = 67, 76.1%) (p < 0.05). We found no differences in maternal characteristics, birth weight, gestational age at delivery and copeptin levels between the two groups. Maternal serum copeptin levels were higher in women who subsequently developed preeclampsia. There was also a significant correlation between copeptin levels and the presence of preeclampsia. (p = 0.002). Conclusions: Copeptin levels are significantly higher in patients who develop preeclampsia.
