BACKGROUND: Gestational diabetes mellitus (GDM) is a serious health problem associated with both foetal and maternal complications. New biomarkers that can predict or help in the early diagnosis of GDM are needed to minimize the hazards of hyperglycaemia in pregnant women and their offspring. We hypothesised a link between levels of microRNA-223 (miRNA-223) and Angiopoietin-Like Protein 8 (ANGPTL8) and GDM.
MATERIALS AND METHODS: The study included 109 patients with confirmed early diagnosed GDM and 103 healthy control pregnant women in their second or third trimester. miRNA-223 and ANGPTL8 blood levels were assessed by real-time RT-PCR and sandwich ELISA, respectively, laboratory markers by standard methods.
RESULTS: There was a significant increase in mean [SD] miRNA-223 and ANGPTL8 in GDM (0.31 [0.06] relative units) and (692 [199] pg/ml), respectively, in the GDM women compared to healthy pregnant women (0.17[0.05] relative units) and (261 [127] pg/ml), respectively, P < 0.001. miRNA-223 and ANGPTL8 correlated significantly with each other (r = 0.38, P < 0.001) and with fasting, 1-h and 2-h postprandial blood glucose levels (all P ≤ 0.002) HbA1 c (P < 0.025), total cholesterol (P < 0.01), LDL-C and triglycerides (both P ≤ 0.005). The ROC area under curve (AUC) (95%CI) was 0.94 (0.91-0.97) for ANGPTL8, 0.92 (0.88-0.96) for miRNA-223 and 0.97 (0.95 - 0.99) for their combination.
CONCLUSIONS: These findings support the hypothesis of involvement of both miRNA-223 and ANGPTL8 in the pathogenesis of GDM. The difference between levels in GDM patients and in control pregnant women indicates potential use for early diagnosis or prediction of GDM.
