Correlation between lipid peroxidation and non-enzymatic antioxidants in pregnancy induced hypertension

The present study was designed to evaluate the lipid peroxidation and non-enzymatic antioxidants in pregnancyinduced hypertension (PIH) compared with healthy normal pregnant and non-pregnant as controls. 75 cases were studied of which 25 were normal healthy controls (Group A), 25 healthy pregnant women (Group B) of third trimester and 25 were PIH (Group C) of the same trimester. In PIH, malondialdehyde a lipid peroxidation product was significantly increased as compared to normal pregnant and non-pregnant controls. The nonenzymatic antioxidants like reduced glutathione, Vitamin-E, Vitamin-C and Vitamin-A were significantly decreased in normal pregnants as compared to controls. A further significant decrease was noticed in PIH compared to normal pregnants. A significant negative correlation was detected between lipid peroxidation and non-enzymatic antioxidant levels. Our study clearly indicates a relationship between elevated lipid peroxidation, decreased non-enzymatic antioxidant in PIH. The measurement of non-enzymatic antioxidants in plasma may be useful predictor of the likely development of PIH.
