Abstract

Introduction: Preeclampsia is a pregnancy-specific condition characterized by hypertension and proteinuria. Preeclampsia remains a disease of theories as its real etiology has remained elusive. Endothelial cell dysfunction may play a role in the pathobiology of preeclampsia. There is some evidence to suggest that endothelial cell damage result from oxidative stress. The aim of the study was to measure oxidative stress markers in preeclampsia. Material and Methods: Total antioxidant capacity (TAC), lipid peroxidation (LPO) and thiol groups was measured in 20 women with preeclampsia, 20 normal pregnant women and 20 nonpregnant women. All three women groups were matched with respect to age, BMI, parity and gestational age. Oxidative stress markers were measured by spectrophotometer methods. Results: Serum concentration of LPO was significantly higher in preeclampsia (17.7 + 3.8 nmol/ml) as compared with nonpregnant women (10.4 + 0.48 nmol/ml, p< 0.0001). TAC in preeclamptic women was lower than those in normal pregnant and non-pregnant women, but not statistically significantly. There was no significant difference between the mean concentrations of thiol groups in the women groups. Conclusion: Increased levels of LPO products may cause peroxidative damage of vascular endothelium and result in clinical symptoms of preeclampsia. However, further experimental and clinical studies are necessary to clarify the pathogenesis of preeclampsia.
