摘要

Obesity in pregnant women has been associated with an increased risk of maternal complications, including gestational diabetes mellitus (GDM), a process that is related to oxidative stress (OS). To evaluate the bio-markers of OS in red blood cells (RBCs), we assigned 80 pregnant women to one of three groups: control (n = 28), overweight (n = 26) and obese (n =26). Then, we measured in plasma, the levels of glucose, triacyl-glycerol (TAG), insulin, free fatty acids (FFAs), leptin and cytokines (e.g. interleukin-6 [IL-6] and tumor necrosis factor-alpha ITNF-alpha]) and OS biomarkers, such as lipohydroperoxides (LHP), malondialdehyde (MDA) and protein carbonylation (PC) in RBCs. We found significant positive correlations between OS biomarkers, body mass index (BMI) and pregnancy progression. Seven (26.9%) obese women who were diagnosed with GDM at 24-28 weeks of pregnancy showed significantly increased concentrations of FFAs, insulin, leptin, TNF-alpha and biomarkers of OS measured at 12-13 weeks of gestation. We propose to quantify LHP, MDA and PC in membranes of erythrocytes as possible markers to diagnose GDM from weeks 12-14.
