Background: To investigate the correlations of serum homocysteine (Hcy), α2-Heremans-Schmid glycoprotein (AHSG), and C-reactive protein (CRP) with insulin resistance (IR), 25-hydroxyvitamin D (25-OH-VD), and blood lipids in patients with gestational diabetes mellitus (GDM) by detecting their levels.
Methods: A total of 72 GDM patients (GDM group) and 72 healthy pregnant women (control group) delivered in our hospital from February 2017 to January 2019 were randomly selected. The basic data, somatological parameters [height, weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio (WHR), blood pressure, and body fat content], and biochemical indexes (glucose metabolism indexes, lipid metabolism indexes, Hcy, AHSG, CRP, and 25-OH-VD) were compared between the two groups. Additionally, Pearson’s correlation analysis was employed to analyze the correlations among indicators.
Results: In comparison with the control group, the GDM group had a higher average rate of family history of DM (p < 0.05), larger waist circumference and WHR, and higher body fat content (p < 0.05). Besides, the fasting plasma glucose (FPG), 1-hour plasma glucose (1hPG) and 2-hour plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), homeostasis model assessment (HOMA)-IR, triglyceride (TG), total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C) were higher in the GDM group than those in the control group (p < 0.05), while the high density lipoprotein cholesterol (HDL-C) was lower in the GDM group than that in the control group (p < 0.05). Compared with those in the control group, the serum Hcy, AHSG, and CRP levels rose, while the serum 25-OH-VD level declined in the GDM group (p < 0.05). The results of Pearson’s correlation analysis revealed that HOMA-IR had positive correlations with FPG, FINS, TC, TG, Hcy, AHSG, and CRP (r = 0.591, 0.825, 0.312, 0.234, 0.458, 0.647, 0.487, p < 0.05) and negative correlation with 25-OH-VD (r = -0.323, p < 0.05). CRP was positively correlated with HOMA-IR, TC, and AHSG (r = 0.485, 0.331, 0.226, p < 0.05), negatively associated with 25-OH-VD (r = -0.443, p < 0.05), and had no correlation to TG and Hcy (r = 0.019, 0.058, p > 0.05). AHSG displayed positive correlations with HOMA-IR, TC, TG, and CRP (r = 0.647, 0.321, 0.314, 0.226, p < 0.05) and no association with Hcy and 25-OH-VD (r = 0.058, -0.034, p > 0.05).
Conclusions: GDM patients have increased serum Hcy, AHSG, and CRP levels and a decreased serum 25-OH-VD level, indicating that serum Hcy, AHSG, CRP, and 25-OH-VD are correlated with glucose and lipid metabolism disorders in GDM patients.
