Abstract:
Objective:To explore the predictive value of serum betatrophin and ficolin-3 during early pregnancy for gestational diabetes mellitus (GDM).Methods:Using a prospective research method, from June 2018 to June 2019, 7 to 13 weeks pregnant women were selected in Yan′an Hospital of Kunming City, and their fasting peripheral venous blood samples were reserved. At 24 to 28 weeks of pregnancy, oral glucose tolerance test (OGGT) was performed. Sixty-five cases were diagnosed as GDM (GDM group), and 60 pregnant women with normal OGGT result and matched age and gestational weeks were selected as normal group. In addition, 60 non-pregnant healthy women with matched age were selected as control group. The serum levels of betatrophin and ficolin-3 were measured in GDM group, normal control group (during 7 to 13 weeks of gestation) and control group were measured by enzyme linked immunosorbent assay method. Pearson test was used to analyze the correlation between serum betatrophin, ficolin-3 and glycolipid metabolism indexes during 24 to 28 weeks of gestation. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum betatrophin and ficolin-3 during early pregnancy for GDM.Results:The serum betatrophin and ficolin-3 in GDM group were significantly higher than those in normal group and control group: (35.69 ± 6.15) ng/L vs. (23.90 ± 7.68) and (19.68 ± 6.33) ng/L, (31.75 ± 10.30) μg/L vs. (22.88 ± 12.71) and (18.47 ± 9.54) μg/L, the betatrophin and ficolin-3 in normal group were significantly higher than those in control group, and there were statistical differences ( P<0.05). The correlation analysis result showed that serum betatrophin was positive correlation with total cholesterol (TC), glycosylated hemoglobin (HbA 1c) and homeostatic model assessment insulin resistance index (HOMA-IR) ( r = 0.585, 0.440 and 0.735; P<0.01); the serum ficolin-3 was positively correlated with HbA1c ( r = 0.673, P<0.01), and negatively correlated with high-density lipoprotein cholesterol (HDL-C) ( r = - 0.520, P<0.01). ROC curve analysis result showed that the areas under curve of betatrophin and ficolin-3 for predicting GDM were 0.829 and 0.795, 95% CI 0.753 to 0.905 and 0.718 to 0.872, and the optimum critical values were 27.69 ng/L and 29.72 μg/L, with a sensitivity of 89.36% and 84.58%, a specificity of 72.14% and 79.64% and Yorden index of 0.62 and 0.59. The areas under curve of betatrophin combined with ficolin-3 for predicting GDM was 0.923, 95% CI 0.868 to 0.978, with a sensitivity of 91.25%, a specificity of 87.24% and Yorden index of 0.86. Conclusions:GDM pregnant women have abnormal expression of serum betatrophin and ficolin-3 during early pregnancy, and the indexes are related to glycolipid metabolism. Serum betatrophin and ficolin-3 during early pregnancy have certain predictive value for GDM.
