Abstract

Objective: The main aim of this study was to investigate thiol/disulfide homeostasis at 24-28 weeks of pregnancy and to evaluate whether it is predictive for adverse perinatal outcomes or not in gestational diabetes mellitus (GDM).Methods: A total of 110 pregnant women at 24-28 weeks of pregnancy (74 GDM patients and 36 age- and BMI-matched healthy pregnant women) were enrolled in this prospective case-control study. Thiol/disulfide homeostasis was evaluated with a novel spectrophotometric method to determine if there is an association with adverse perinatal outcomes in GDM, by using logistic regression analysis.Results: GDM patients, with decreased native thiol levels at 24-28 weeks (OR: 4.890, 95% CI: 1.355-5.764, p=0.015) and with higher pre-pregnancy BMI (OR: 1.280, 95% CI: 1.072-1.528, p=0.006), were found to be at increased risk of adverse perinatal outcomes in GDM. There were no statistically significant differences in thiol/disulfide homeostasis between diet- and insulin-treated GDM subgroups. Additionally, 1-h and 2-h glucose levels on 100g OGTT were found to be predictive for the insulin need in achieving good glycemic control in GDM (OR: 1.022, 95% CI: 1.005-1.038, p=0.010 and OR: 1.019, 95% CI: 1.004-1.035, p=0.015).Conclusions: GDM patients, with decreased native thiol levels at 24-28 weeks of pregnancy and with higher pre-pregnancy BMI, have an increased risk of possible adverse perinatal outcomes. Also, increased 1-h and 2-h glucose levels on 100g OGTT can predict the need for insulin treatment for GDM.
