Oxidative stress in placental pathology

Area of Science:

• Obstetrics and Gynecology
• Perinatology
• Pathology

Background:

• The placenta facilitates crucial nutrient and oxygen exchange between mother and fetus.
• Adequate spiral artery remodelling during placentation is essential for healthy placental function.
• Impaired placentation leads to suboptimal placental function, manifesting as pregnancy complications.

Purpose of the Study:

• To review the causes and role of placental oxidative stress in placental pathology.
• To explore the clinical consequences of impaired placental function and oxidative stress.
• To describe therapeutic strategies for placental and fetal hypoxia.

Main Methods:

• Literature review of placental function, hypoxia, and oxidative stress.
• Analysis of placental lesions and their impact on oxygen exchange.
• Examination of clinical biomarkers for oxidative stress.

Main Results:

• Hypoxia due to impaired placentation or placental lesions causes oxidative stress.
• Oxidative stress damages placental proteins, lipids, and DNA.
• Biomarkers like malondialdehyde indicate oxidative stress in placental dysfunction.

Conclusions:

• Placental oxidative stress is implicated in the development of placental pathology and adverse pregnancy outcomes.
• Understanding oxidative stress mechanisms is vital for managing preeclampsia and fetal growth restriction.
• Therapeutic interventions targeting hypoxia and oxidative stress are under investigation.
