Preeclampsia is a complex condition characterized by elevated blood pressure and organ damage involving kidneys or liver, resulting in significant morbidity and mortality for both the mother and the fetus. Increasing evidence suggests that oxidative stress, often caused by mitochondrial dysfunction within fetal trophoblast cells may play a major role in the development and progression of preeclampsia. Oxidative stress occurs as a result of an imbalance between the production of reactive oxygen species (ROS) and the capacity of antioxidant defenses, which can lead to placental cellular damage and endothelial cell dysfunction. Targeting oxidative stress appears to be a promising therapeutic approach that has the potential to improve both short- and long-term maternal and fetal outcomes, thus reducing the global burden of preeclampsia. The purpose of this review is to provide a comprehensive account of the mechanisms of oxidative stress in preeclampsia. Furthermore, it also examines potential interventions for reducing oxidative stress in preeclampsia, including natural antioxidant supplements, lifestyle modifications, mitochondrial targeting antioxidants, and pharmacological agents.A better understanding of the mechanism of action of proposed therapeutic strategies targeting oxidative stress is essential for the identification of companion biomarkers and personalized medicine approaches for the development of effective treatments of preeclampsia.
子痫前期是一种复杂的病症,其特征为血压升高以及涉及肾脏或肝脏的器官损害,会导致母亲和胎儿出现显著的发病率和死亡率。越来越多的证据表明,通常由胎儿滋养层细胞内的线粒体功能障碍引起的氧化应激可能在子痫前期的发生和发展中起主要作用。氧化应激是由于活性氧(ROS)的产生与抗氧化防御能力之间的失衡而发生的,这会导致胎盘细胞损伤和内皮细胞功能障碍。针对氧化应激似乎是一种有前景的治疗方法,有可能改善母婴的短期和长期结局,从而减轻全球子痫前期的负担。本综述的目的是全面阐述子痫前期中氧化应激的机制。此外,还研究了降低子痫前期氧化应激的潜在干预措施,包括天然抗氧化剂补充剂、生活方式改变、线粒体靶向抗氧化剂和药物制剂。更好地理解针对氧化应激的拟议治疗策略的作用机制,对于识别伴随生物标志物以及开发子痫前期有效治疗方法的个性化医学方法至关重要。
