Although vaspin is regarded an insulin-sensitizing adipokine, its role in gestational diabetes mellitus (GDM) is currently unknown. We aimed to evaluate serum vaspin levels and their correlation with insulin resistance in women with and without GDM. Forty-four women with GDM (GDM Group 20 managed with diet only (GDM-diet) and 24 with diet plus insulin (GDM-insulin)) and 44 age-matched pregnant women with normal glucose tolerance (control group) were studied. Serum glucose, lipids, uric acid, insulin, and vaspin were measured at the 2nd and 3rd trimesters of pregnancy and postpartum. The quantitative insulin sensitivity check index (QUICKI) and homeostasis model of assessment-insulin resistance (HOMA-IR) were calculated. Circulating vaspin levels decreased significantly postpartum in all groups (P<0.001), but did not differ between GDM or GDM subgroups and control group in any time point. At the 3rd trimester of pregnancy vaspin was positively correlated to insulin (P=0.022), HOMA-IR (P=0.016) and triglycerides (P=0.033) and negatively correlated to QUICKI (P=0.016) in the GDM women, but not in the Controls. These correlations were not observed at the 2nd trimester or postpartum. Vaspin, in contrast to HOMA-IR, could not independently predict GDM in binary logistic regression. In patients with GDM, insulin treatment did not affect vaspin levels. In conclusion, our data suggest that vaspin levels gradually decrease from the 2nd trimester to postpartum; however, decreases are similar between women with or without GDM. Serum vaspin cannot independently predict GDM and it is not affected by the degree of glucose metabolism deregulation or the exogenous administration of insulin.
