Özet
Background: Although gestational diabetes may result in elevated leptin, osteocalcin, and TNF-α (Tumor necrosis factor) levels, impact of those parameters on neonatal outcome is not well established. Objectives: The aim of the current study was to evaluate whether cord blood leptin, TNF α, and osteocalcine have a predictive value for neonatal complications due to maternal GDM. Methods: This cohort study was performed at Near East East University hospital, Nicosia, Cyprus. All pregnant females under follow-up of the department of gynocology and obstrectrics between years 2010 and 2012 were invited to participate. Those, who gave consent, were enrolled. Expecting mothers were categorized as GDM and normal pregnancy. Forty-one (21.5%) of the pregnancies were GDM and 159 (78.5%) were normal. Cord blood samples were obtained at delivery. Osteocalcin, leptin, and TNF-α levels and neonatal complications were evaluated thereafter. Results: Comparasion of pregnancy complications between groups revealed no significant differences except for more frequent maternal hypothyroidism in the GDM group (P < 0.001). The GD group’s cord blood osteocalcin levels (44.69 ± 27.6 ng/mL and 35.23 ± 22.9 ng/mL in the control group (P: 0.037)) and frequency of neonatal hypoglycemia were significantly higher than controls (P: 0.047), whereas cord blood TNF α and leptin levels were not statistically different (P > 0.05). Newborns with hypoglycemia showed higher cord blood osteocalcine, TNF-α, and leptin. In addition, osteocalcin levels were significantly higher in cord blood of LGA babies born from GDM mothers (50.41 ± 32.79 and 35.19 ± 20.18 ng/mL). Conclusions: In this study, cord blood leptin, osteocalcine, and TNF-α were significantly correlated with neonatal hypoglycemia. Moreover, cord blood osteocalcin levels were significantly higher in the GDM group. This increase in osteocalcin in the GDM group, may be related to the regulation of blood glucose levels by osteocalcin.
