Abstract

Introduction

Oxidative stress is closely related to the pathophysiology of gestation, where the placenta is susceptible to oxidative damage, contributing to the onset of gestational complications. Currently, few studies evaluate the use of oxidative markers for prediction of risk of gestational complications. However, there are some reports that suggest these biomarkers as potential prognostic biomarkers. Therefore, the objective of this study was to compare the biomarkers of oxidative stress from gestations with and without complications, and also evaluate the delta of variation in these markers from the first gestational trimester.

Material and Methods

A total of 45 pregnant women were evaluated during the three gestational trimesters, of whom 15 developed gestational complications by the end of gestation. The evaluated oxidative damage markers were thiobarbituric acid reactive substances and nitric oxide dosage. Evaluation of the antioxidant system was performed by the quantification of vitamin C, sulfhydryl groups, total antioxidant capacity, plasmatic iron reduction ability, the evaluation of catalase and delta-aminolevulinate dehydratase enzymatic activity.

Results

According to the results, the markers of oxidative damage are increased, and the antioxidant profile decreased, in the third trimester of complicated pregnancies as compared to uncomplicated pregnancies. Moreover, the delta of variation in both oxidative damage markers and antioxidants was higher in complicated gestations as compared to uncomplicated gestations, thus suggesting a higher oxidative stress in pregnancies with complications.

Conclusions

Oxidative stress parameters appear altered in pregnant women with gestational complications. The markers to oxidative stress can be possible biomarkers, helping in understanding mechanisms underlying the associations between complications during pregnancy and various health outcomes.
