Abstract

Aim: To examine concentrations of three cardiovascular propeptides in umbilical cord plasma of neonates born to mothers with Type 1, Type 2 and gestational diabetes. Measurement of cardiovascular markers in umbilical cord plasma may potentially help identify neonates at risk of postnatal complications. Neonates born to mothers with diabetes have an increased risk of neonatal morbidity and mortality, and measurement of these new biomarkers may potentially help identify neonates at risk of these complications. Subjects & methods: Copeptin, midregional proadrenomedullin (MR-proADM) and mid-regional pro-A-type natriuretic peptide (MR-proANP) were measured in cord plasma of neonates (n = 63) born to mothers with the three types of diabetes. Associations with maternal glycemic control, mode of delivery and neonatal metabolic acidosis were examined. Results: Umbilical cord plasma copeptin concentrations were lowest in neonates after elective cesarean sections (6.1 pmol/l; interquartile range [IQR]: 4.5-9.1) compared with emergency cesarean sections (156 pmol/l; IQR: 9.6-311; p = 0.019) and vaginal delivery (831 pmol/l; IQR: 107-2407; p < 0.0001). MR-proADM was also affected by mode of delivery; however, this seemed more likely to be caused by an inverse association with the acid-base balance. In this population, only MR-proANP plasma concentrations were related to type of diabetes. Neonates born to mothers with Type 1 diabetes had higher concentrations (median 260 pmol/l; IQR: 222-318) compared with Type 2 diabetes (175 pmol/l; IQR: 169-200; p = 0.003) and gestational diabetes (200 pmol/l; IQR: 149-276; p = 0.009). Conclusion: Umbilical cord plasma copeptin and MR-proADM concentrations primarily reflect perinatal stress associated with mode of delivery and the degree of fetal acidosis, whereas MR-proANP concentrations are higher in neonates born to mothers with Type 1 diabetes.
