Abstract

Objective: Pre-eclampsia is a significant health problem and is the leading cause of maternal and perinatal mortality and morbidity. Low birth weight and prematurity are very common in pre-eclamptic mothers. Pre-eclampsia is associated with oxidative stress in the maternal circulation. To observe the effect of pre-eclampsia on neonates, this study was designed to explore oxidative stress and anti-oxidant status in the fetal circulation in pre-eclampsia.

Materials and Methods: For this purpose, we collected cord bloods during delivery from Bangabandhu Sheikh Mujib Medical University. Twenty samples were collected from uncomplicated (normotensive) mothers and 15 samples were collected from pre-eclamptic mothers (maternal age matched). Thiobarbituric acid reactive substances (TBARS), lipid hydroperoxide, protein carbonyl value, lipid profile, total anti-oxidant status (TAS), vitamin C, serum total protein and albumin were measured.

Results: It was observed that TBARS and lipid hydroperoxide were significantly (P < 0.001) increased, protein carbonyl content were also significantly (P < 0.001) increased but total anti-oxidant status (P < 0.001) and vitamin C level were significantly (P < 0.05) decreased in cord blood from pre-eclamptic mother compared to control group. Cholesterol, TG, LDL level was elevated and HDL were lowered in cord blood in pre-eclamptic group compared to normotensive group. In pre-eclamptic group, cord blood total protein, albumin and globulin level were significantly decreased compared to control group.

Conclusions: As pre-eclampsia is associated with increased oxidative stress and decreased anti-oxidant status, the results of these investigations suggest that oxidative stress and antioxidant status are altered towards proatherogenic level in cord blood of pre-eclamptic women which may ultimately be responsible for different complications of newborn babies of pre-eclamptic mothers.
