Abstract:
Objective:To observe the predictive value of serum LP-PLA2, PAPP-A and C-peptide for patients with diabetes (GDM) patients during pregnancy.Methods:From Jan.2018 to Jan. 2022, 400 patients with gestational diabetes mellitus (GDM group) and 400 healthy pregnant women who underwent prenatal examinations (control group) were enrolled. The serum prenatal lipoprotein-associated phospholipase A2 (Lp-PLA2) , pregnancy-associated plasma protein-A (PAPP-A) , C-peptide and neonatal blood glucose levels were compared between the two groups. The correlation of serum Lp-PLA2, PAPP-A and C-peptide with neonatal hypoglycemia in GDM patients was analyzed, and the value of area under receiver operating curve (ROC) for predicting neonatal hypoglycemia was analyzed.Results:The serum levels of Lp-PLA2, PAPP-A and C-peptide in the GDM group were higher than those in the control group (33.57±6.52 nmol/min/ml vs 23.45±4.38 nmol/min/ml, 26.72±4.79 ng/ml vs 23.57±3.08 ng/ml, 27.32±3.97 ng/mL vs 25.15±0.71 ng/mL) ( P<0.05) . The incidence of neonatal hypoglycemia in the GDM group was higher than that in the control group (16.0% vs 4.5%) ( P<0.05) .The serum levels of Lp-PLA2, PAPP-A and C-peptide in GDM patients with neonatal hypoglycemia were higher than those in neonatal normoglycemic patients (35.82±6.42 nmol/min/ml vs 32.29±6.03 nmol/min/ml, 27.72±4.21 ng/ml vs 25.35±3.98 ng/ml, 32.39±4.78 ng/mL vs 22.18±3.94 ng/mL) ( P<0.05) . Logistic regression analysis showed that high levels of serum Lp-PLA2, PAPP-A and C-peptide in the GDM group were independent risk factors for neonatal hypoglycemia. Serum Lp-PLA2, PAPP-A and C-peptide of GDM patients had certain predictive value for the occurrence of neonatal hypoglycemia, among which C-peptide had the greatest predictive value. Conclusion:High levels of serum Lp-PLA2, PAPP-A and C-peptide are independent risk factors for neonatal hypoglycemia in GDM patients, and have certain predictive value, which can provide a reference for clinical prediction of its occurrence.
