A quantitative evaluation of total antioxidant status and oxidative stress markers in preeclampsia and gestational diabetic patients in 24–36 weeks of gestation

ObjectiveTo assess the plasma and serum maternal total antioxidant status, circulating levels of lipid peroxidation breakdown products (MDA), protein oxidation markers (AOPPs), myeloperoxidase (MPO) and lipid hydroperoxide (LHP) in preeclampsia, gestational diabetes mellitus (GDM) patients and compare them with noncomplicated normal pregnancies between 24 and 36 weeks of gestation.Study design27 GDM, 27 preeclampsia and 29 noncomplicated singleton pregnancies were included. The blood samples were taken at the diagnosis of disease.ResultsTAS was decreased in GDM and preeclampsia when compared to normal pregnancies. MDA levels were higher only in GDM group than normal pregnancies. AOPP levels were increased but MPO and LHP levels were not changed both in GDM and preeclampsia when compared to normal pregnancies.ConclusionsWe concluded that increased oxidative stress and reduction in antioxidant defense mechanisms may contribute to disease processes both in GDM and preeclampsia.
