Abstract
OBJECTIVE: The aim of the study was to assess the potential role of oxidative stress and lipid status in the onset of preeclampsia.METHODS: 138 high-risk pregnant women were prospectively followed. Assessment of oxidative stress (TAS, TOS, AOPP and SH groups) and lipid status (t-C, LDL-C, HDL-C, TGC, APO-A1, APO-B) was carried out during the pregnancy.RESULTS: 30 women developed preeclampsia. TGC, atherogenic index of plasma, TAS and SH levels were higher in women who subsequently developed preeclampsia (p<0.05).CONCLUSION: Oxidative stress and lipid status disturbance have a potential role in the onset of preeclampsia in high risk pregnancies.

Abstract
OBJECTIVES The goal of this study was to investigate metabolic changes in lipids and oxidative stress parameters in the first trimester of pregnancy with the more specific aim of estimating the significance and strength of researched parameters in the prediction of preeclampsia. DESIGN AND METHODS The study included 87 high-risk pregnant (HRG) female subjects, 14 with developed preeclampsia (PEC) and 43 healthy pregnant female subjects matched for gestational age (CG). Thiobarbituric acid-reactive substances (TBARS) concentration, lipid hydroperoxides (LOOH), pro-oxidant antioxidant balance (PAB) and total oxidative status (TOS) were measured as oxidative stress markers, while total antioxidant capacity (TAC) was measured as an antioxidative defense parameter. The Atherogenic Index of Plasma (AIP) was calculated as the base 10 logarithm of the ratio of the plasma concentration of triglycerides (TG) to the plasma concentration of high-density lipoprotein cholesterol (HDL-C), with each concentration expressed in mmol/L. RESULTS The results have shown that lipid indices, especially AIP, were significantly higher in the first trimester of HRG (p < 0.001) and PEC (p < 0.001). Oxidative stress parameters were significantlly higher, while TAC was significantly lower in HRG vs. CG [0.7 ± 0.15 vs 1.1 ± 0.16; (p < 0.001)] and in PEC [0.6 ± 0.12 vs 1.1 ± 0.16; (p < 0.001)] vs. CG. Also, in the HRG, results have shown an independent association of AIP with the preeclampsia development (p < 0.05), while placental growth factor did not show the expected level of significance (p = 0.648). Analysis of the Receiver Operating Characteristics (ROC) curves indicated that certain parameters included in the research model have very good diagnostic accuracy for preeclampsia (AUC = 0.856). CONCLUSIONS AIP is associated with high-risk pregnancies. Furthermore, our results firmly underscored AIP as a potential marker for preeclampsia prediction.
