Review reveals how maternal-placental oxidative stress imbalance drives endothelial dysfunction in preeclampsia, suggesting therapeutic roles for antioxidant support.

Key Points

Evaluate the hypothesis that an imbalance between elevated oxidative stress and deficient antioxidant defenses across maternal and placental compartments drives the pathogenesis of preeclampsia.
Narrative review synthesizing evidence on maternal and placental oxidative stress, lipid peroxidation, and antioxidant enzyme levels in preeclampsia.
Conceptual modeling of pathophysiological cascades connecting preexisting maternal risks, placental mediator release, and systemic endothelial dysfunction.
Placental antioxidant enzyme deficiency leads to uncontrolled lipid peroxidation alongside increased production of thromboxane and tumor necrosis factor-alpha.
Maternal leukocytes circulating through the intervillous space become activated by placental factors, mediating widespread maternal oxidative stress and endothelial dysfunction.
Clinical manifestations emerge predominantly in the third trimester when accelerated placental growth overwhelms maternal antioxidant compensatory capacity.
