Trace elements and antioxidant enzymes associated with oxidative stress in the pre-eclamptic/eclamptic mothers during fetal circulation

Summary Background & aims Pre-eclampsia is associated with oxidative stress in the maternal circulation. The aim of the study was to access the oxidative stress status by quantification of byproducts generated during lipid peroxidation; deficient antioxidant activity and inadequate trace elements during oxidative damage in the umbilical cord blood of pre-eclamptic/eclamptic mothers and its effect on the fetal outcome. Methods In a case control study umbilical cord blood samples were collected during delivery from cases of pre-eclamptic/eclamptic mothers and from normotensive (uncomplicated pregnancy) subjects as controls. Concentrations of malondialdehyde, trace elements (Zn, Cu, Se, Mg) and antioxidant enzymes (SOD, GPx) were determined. Results Decreased levels of Zinc ( p
