Abstract
SCUBE-1 (Signal peptide-CUB (complement C1r/C1s, Uegf, and Bmp1)-EGF (epidermal growth factor)-domain-containing protein 1) is a novel marker of ischemia, which is a cell surface-secreted protein in the platelets and endothelial cells. The aim of the study is to measure serum SCUBE-1 levels and investigate their association with uteroplacental blood flow in patients with preeclampsia. The study was conducted on patients with preeclampsia. Maternal serum SCUBE1 and IMA levels were the main outcomes. The control group consisted of gestational-age-matched pregnant women. Fetal umbilical artery (UA) pulsatility index (PI), middle cerebral artery PI, cerebroplacental ratio (CPR), and maternal uterine artery (UtA)-PI were also examined, and correlation analysis was performed to reveal the association between maternal serum SCUBE1 levels and Doppler findings. The study group consisted of thirty-two preeclamptic patients, and the control group consisted of thirty-two uncomplicated singleton pregnancies. Maternal serum SCUBE1 and IMA levels were significantly higher in preeclamptic women compared to the control group (p < 0.000, p < 0.004, respectively). Mean UtA-PI values and fetal UA-PI values were significantly higher in preeclamptic pregnant women compared to the control group (p < 0.05, p < 0.05, respectively). However, the average CPR was significantly lower in pregnant women with preeclampsia (p < 0.05). While no significant correlation was found between maternal serum SCUBE1 levels and UA-PI and CPR (p > 0.05, p > 0.05, respectively), a significant correlation was found between right and left UtA-PI (p < 0.004, p < 0.006, respectively). The maternal serum SCUBE1 level is increased in patients with preeclampsia, and this increase is significantly correlated with the maternal uterine artery pulsatility index.
