    Abstract:
    OBJECT: The aim of this study was to evaluate the lipid and protein oxidation and antioxidant function in preeclampsia patients and in normotensive pregnant women, as well as, to assess an association with the severity of the disease. METHOD: The study was carried out in 30 patients with mild preeclampsia, 30 with severe preeclampsia, and in 50 normotensive pregnant women during the third trimester of pregnancy. Lipid peroxides in serum, placental and decidual tissues and serum protein carbonyls and some of the antioxidants were measured by spectrophotometric methods. One-way analysis of variance, chi-square test and Pearson correlation test were used for the statistical analyses. Logistic regression procedures were used to calculate odds ratios (OR). RESULTS: Lipid peroxides in serum, placenta and decidua basalis and protein carbonyls in serum were significantly increased, and vitamin E and total carotene levels in serum were significantly decreased especially in women with severe preeclampsia compared with mild preeclampsia and controls. A significant correlation was detected between diastolic blood pressure and lipid peroxides in serum, placental and decidual tissues and serum protein carbonyls. Furthermore, there was significant correlation between antioxidant vitamins and lipid and protein oxidation products in severe preeclamptic patients. Also, logistic regression analysis showed that changes in serum, placental and decidual lipid peroxides and serum protein carbonyls, vitamin E and total carotene concentrations were significantly associated with preeclampsia. CONCLUSION: Our findings suggest that lipid and protein oxidation may be an important factor in the pathogenesis of preeclampsia. Since antioxidant vitamins are significantly decreased in both severe and mild preeclamptic pregnants, early supplementation with antioxidants may be beneficial in preeclamptic patients.
