- Abstract: Objective To investigate the changes in the expression levels of serum glutathione peroxidase 3(GPX3)and aquaporin 9(AQP9)in pregnant women with gestational diabetes mellitus(GDM)and their relationships with pregnancy outcomes.Methods A total of 200 pregnant women with GDM(GDM group)and 200 healthy pregnant women(control group)were enrolled as study subjects.The GDM group was further divided into adverse pregnancy outcome(APO)subgroup(n=22)and favorable pregnancy outcome subgroup(n=178)based on pregnancy outcomes.The expres-sion levels of serum GPX3 and AQP9 were detected by enzyme-linked immunosorbent assay.Multivari-ate Logistic regression analysis was used to screen for influencing factors of APO in GDM pregnant women.Receiver operating characteristic(ROC)curves were plotted to analyze the predictive perform-ance of serum GPX3 and AQP9 expression levels for APO in GDM pregnant women.Results Com-pared with the control group,the serum GPX3 expression level was decreased,and the serum AQP9 ex-pression level was increased in the GDM group(P<0.05).The incidence of APO among the 200 GDM pregnant women was 11.00%(22/200).Compared with the favorable pregnancy outcome subgroup,the APO group had higher levels of homeostasis model assessment-insulin resistance index(HOMA-IR),fasting blood glucose,glycated hemoglobin(HbA1c),and AQP9,and lower levels of GPX3(P<0.05).Multivariate Logistic regression analysis revealed that elevated HOMA-IR,HbA1c,and AQP9 were independent risk factors for APO in GDM pregnant women(P<0.05),while elevated GPX3 was an independent protective factor(P<0.05).The ROC curve showed that the areas under the curve(AUCs)for predicting APO in GDM pregnant women were 0.784(95%CI,0.673 to 0.881)for serum GPX3 alone,0.788(95%CI,0.687 to 0.894)for serum AQP9 alone,and 0.906(95%CI,0.805 to 0.972)for their combination,with the AUC for the combined prediction being greater than that for individual prediction(P<0.05).Conclusion The serum GPX3 expression level is de-creased,and the serum AQP9 expression level is increased in GDM pregnant women.Both serum GPX3 and AQP9 are independent influencing factors for APO,and their combined prediction has a higher value for APO in GDM pregnant women.
