Abstract:
Objective To detect the levels of serum angiopoietin-like protein 4 (ANGPTL4) and glucose regulated protein 78 (GRP78), and to explore the relationship between them and poor pregnancy outcomes in patients with gestational diabetes mellitus (GDM).
Methods Three hundred GDM patients were used as the GDM group, and 300 healthy pregnant women from the same pregnancy test period were collected as the control group. Enzyme linked immunosorbent assay (ELISA) was applied to detect serum levels of ANGPTL4 and GRP78. According to the pregnancy outcomes of GDM patients, they were grouped into a good pregnancy outcomes group (174 cases) and a poor pregnancy outcomes group (126 cases). Spearman correlation was applied to analyze the correlation between serum levels of ANGPTL4 and GRP78 and poor pregnancy outcomes. Multivariate logistic regression was applied to analyze the influencing factors of poor pregnancy outcomes in GDM. ROC curve was applied to evaluate the predictive value of serum ANGPTL4 and GRP78 for poor pregnancy outcomes in GDM.
Results The serum ANGPTL4 level in the GDM group was obviously lower than that in the control group (P < 0.01), and the GRP78 level in the GDM group was obviously higher than that in the control group (P < 0.01). The age, gestational week, FBG, HOMA-IR, and serum GRP78 level in the good pregnancy outcomes group were obviously lower than those in the poor pregnancy outcomes group (P < 0.05 to P < 0.01), the pre-delivery BMI and serum ANGPTL4 level in the good pregnancy outcomes group were obviously higher than those in the poor pregnancy outcomes group (P < 0.01). The Spearman correlation analysis showed that the serum level of ANGPTL4 in GDM patients was negatively correlated with poor pregnancy outcomes in pregnant women (P < 0.01), while the level of GRP78 was positively correlated with poor pregnancy outcomes in pregnant women (P < 0.01). Logistic regression analysis showed that serum ANGPTL4, GRP78, age, gestational week, pre-delivery BMI, FBG, and HOMA-IR were all risk factors for poor pregnancy outcomes in GDM patients (P < 0.05 to P < 0.01). The ROC curve results showed that the AUC predicted by the combination of serum ANGPTL4 and GRP78 for poor pregnancy outcomes in GDM patients was obviously higher than that predicted by ANGPTL4 alone (P < 0.05) and GRP78 alone (P < 0.01).
Conclusion The serum ANGPTL4 levels were significantly lower and GRP78 levels were significantly higher in GDM patients, which has certain reference significance for evaluating the pregnancy outcomes of GDM.
