Background: A number of biochemical predictors of preeclampsia have been reported, but little is known about their possible relationship with maternal and fetal outcomes. This study determined serum copeptin in pregnant women with preeclampsia and assessed its relationship with pregnancy outcomes. Materials and Methods: Thirty women with severe preeclampsia (SP), 30 with mild preeclampsia (MP), and 30 with uncomplicated pregnancy were enrolled into this study. Serum copeptin, creatinine, and liver function were determined using enzyme-linked immunosorbent assay and colorimetry as appropriate. Pregnancy outcomes, both maternal and fetal, were taken using standard methods. Results: Copeptin was significantly elevated in preeclampsia subjects compared with controls and in SP compared with MP. Assessing the diagnostic property of copeptin for preeclampsia, the area under the curve for copeptin was 0.99. Nine (30%) and 3 (10%) of SP and MP, respectively had abruptio placenta while 6 (20%), 2 (6.7%), and 1 (3.3%) still births were recorded in SP, MP, and controls, respectively. Neonates of mothers with preeclampsia had significantly lower birth weight, infant length, ponderal index, and head circumference compared with neonates of the controls. Copeptin had a significant inverse relationship with birth weight, ponderal index, head circumference, Apgar score, and infant length in neonates of mothers with preeclampsia. Conclusion: Serum copeptin level in the third trimester could predict preeclampsia and its elevation is associated with adverse perinatal outcome.
