Increased 8-OHdG in umbilical cord blood represents the risk of preeclampsia with Intra-Uterine Growth Restriction (IUGR)

Background: Preeclampsia is a pregnancy-related disease involving multi-organs, characterized by increased blood pressure in the second trimester of pregnancy. Preeclampsia can have short-term and long-term consequences for the mother and the fetus, including intra-uterine growth restriction (IUGR). One of the markers of DNA damage due to oxidative stress due to endothelial dysfunction in preeclampsia is the increase in 8-OHdG levels in cord blood. This study aims to see an increase in 8-OHdG levels in preeclampsia.Methods: This study was a cross-sectional study with a total of 41 patients with preeclampsia and 41 patients with healthy pregnant women at Wahidin Sudirohusodo Hospital and its network. Samples were taken using the purposive sampling method according to the inclusion criteria. This 8-OHdG level was examined using the ELISA kit at the HUMRC laboratory of Hasanuddin University Hospital. The data is then processed statistically using SPSS.Results: This study found 6 patients with PE + IUGR, 31 with PE, and 41 without PE. The examination results of 8-OHdG levels found significant differences between the 3 groups PE + IUGR, PE, and normal pregnancies, which showed a significant relationship between elevated 8-OHdG levels and the incidence of PE accompanied by IUGR (p = 0.006).Conclusion: Elevated 8-OHdG levels are found in preeclampsia, especially in preeclampsia accompanied by IUGR.
