The clinical effects of glycated hemoglobin, fasting blood glucose and serum C-peptide combined screening for gestational diabetes screening and its clinical significance / 中国医师进修杂志

ABSTRACT

Objective:To investigate the clinical effects of glycated hemoglobin, fasting blood glucose and serum C-peptide combined screening for gestational diabetes screening and its clinical significance.Methods:A total of 40 pregnant women with gestational diabetes mellitus (observation group) and 40 pregnant women (control group) in Peking University Medical Lu Zhong Hospital from January 2016 to September 2019 were enrolled. The changes of glycated hemoglobin, fasting blood glucose, and serum C-peptide were compared between the two groups, and the efficacy of combined screening for gestational diabetes was evaluated.Results:The glycated hemoglobin of the pregnant women in the observation group was significantly higher than that in the control group [(8.12 ± 1.14)% vs. (5.23 ± 0.15)%], the serum C-peptide of the pregnant women in the observation group was lower than that in the control group [(1.19 ± 0.28) nmol/L vs. (1.61 ± 0.22) nmol/L], and there were significant differences ( P<0.05). There was no significant difference in fasting blood glucose between the two groups ( P>0.05). When glycosylated hemoglobin, fasting blood glucose and serum C-peptide index was screened combinedly, the sensitivity, specificity, positive predictive value, negative predictive value and the areas under the receiver operation characteristic (ROC) curve were 98.65%, 86.50%, 88.42%, 95.45%, and 0.943, respectively. Compared with all other individual indicators, the difference was statistically significant ( P<0.05). Conclusions:The combined detection of glycosylated hemoglobin, fasting blood glucose and serum C-peptide can more accurately diagnose gestational diabetes mellitus at an early stage.
