Evidence indicates that leptin molecules increase in the circulation of women with eclampsia, inducing oxidative stress, another factor in eclampsia, on cells. (The leptin increase also results in platelet aggregation, most likely contributing to the coagulopathy associated with eclampsia.) [2, 10]

Oxidative stress has been found to stimulate the production and secretion of the antiangiogenic factor activin A from placental and endothelial cells. [9] Studies in pregnant mouse models have proposed that there is a dysregulation in the reactive oxygen species (ROS) signaling pathway. [10, 11]

Studies also suggest that increased systemic leukocyte activity plays a role in the mediation of oxidative stress, inflammation, and endothelial cell dysfunction. Histochemistry studies indicate that there is predominantly an increase in neutrophil infiltration of vasculature in patients with eclampsia. [11]
