Oxidative stress in pregnancy complications Oxidative stress, a physiological imbalance between the production of reactive oxygen species (ROS) and the ability of antioxidants to neutralize them, has been implicated in various pregnancy complications [26]. One of the most studied conditions associated with pregnancy, preeclampsia, involves increased oxidative stress [27,28]. Elevated levels of ROS and reduced antioxidant capacity contribute to endothelial dysfunction, leading to hypertension, proteinuria, and placental abnormalities. The placenta, central to preeclampsia pathophysiology, generates excess ROS, triggering systemic in lammation and endothelial damage [29-33]. Oxidative stress is implicated in the development of insulin resistance and pancreatic β-cell dysfunction observed in Gestational Diabetes Mellitus (GDM) [34]. Increased ROS production impairs insulin signaling pathways, exacerbates in lammation, and contributes to abnormal glucose metabolism. This oxidative imbalance affects More Information

Maternal plasma antioxidant status in the first trimester of pregnancy and development of obstetric complications

Placenta, 2016

Introduction: Oxidative stress is present in pregnancy complications. However, it is unknown if early maternal antioxidant status could influence later development of complications. The use of assisted reproduction techniques (ART) is rising due to the delay of first pregnancy and there is scarce information on its influence on oxidative balance. Objective: To assess the possible relationship between maternal plasma antioxidant status in first trimester of gestation with later development of pregnancy complications, evaluating the influence of ART and nutrition. Methods: Plasma from 98 healthy pregnant women was obtained at week 10, nutrition questionnaires filled and women were followed until delivery. We evaluated biomarkers of oxidative damage (carbonyls, malondialdehyde-MDA), antioxidants (thiols, reduced glutathione, phenolic compounds, catalase, superoxide dismutase activities) by spectrophotometry/fluorimetry and melatonin (ELISA). Antioxidant status score (Antiox-S) was calculated as the computation of antioxidants. Diet-antioxidants relationship was evaluated through multiple correspondence analysis. Results: Melatonin and carbonyls exhibited a negative correlation. No difference in oxidative damage was found between groups, but Antiox-S was significantly lower in women who developed complications. No differences in oxidative damage or Antiox-S were found between ART and no-ART pregnancies. High consumption of foods of vegetable origin cluster with high plasma levels of phenolic compounds and with high Antiox-S score. Conclusions: In early normal gestation, low plasma antioxidant status, assessed through a global score, associates with later development of pregnancy complications. Larger ACCEPTED MANUSCRIPT population studies could help to determine the value of Antiox-S as predictive tool and the relevance of nutrition on maternal antioxidant status.

The Role of Oxidative Stress and Antioxidant Balance in Pregnancy

Mediators of Inflammation, 2021

It has been widely known that oxidative stress disrupts the balance between reactive oxygen species (ROS) and the antioxidant system in the body. During pregnancy, the physiological generation of ROS is involved in a variety of developmental processes ranging from oocyte maturation to luteolysis and embryo implantation. While abnormal overproduction of ROS disrupts these processes resulting in reproductive failure. In addition, excessive oxidative stress impairs maternal and placental functions and eventually results in fetal loss, IUGR, and gestational diabetes mellitus. Although some oxidative stress is inevitable during pregnancy, a balancing act between oxidant and antioxidant production is necessary at different stages of the pregnancy. The review aims to highlight the importance of maintaining oxidative and antioxidant balance throughout pregnancy. Furthermore, we highlight the role of oxidative stress in pregnancy-related diseases.
