Purpose: The purpose of this study was to analyse ghrelin concentrations in the umbilical cord of pregnant women with a diagnosis of gestational diabetes mellitus. The relationship between ghrelin concentrations and birth weights was investigated.

Materials and methods: Sixty pregnant women with gestational diabetes mellitus and 64 healthy pregnant women with three oral glucose tolerance test results within normal limits were included in the study. Following birth but before extraction of the placenta, 10-ml blood samples were drawn from the umbilical vein in both groups. Ghrelin concentrations were measured.

Results: The mean birth weights of the babies born to mothers with GDM were higher than those in the control group (P=0.04). The cord blood ghrelin levels in pregnant women with GDM were significantly lower than those of the healthy women in the control group (879.6 pg/ml vs 972.2 pg/ml; P=0.03). The umbilical cord blood ghrelin concentrations in pregnant women with GDM undergoing insulin therapy were significantly lower than those of the control group (792.61 pg/dl vs 972.2 pg/dl; P=0.01). Inverse correlations were detected between umbilical cord blood ghrelin levels and birth weights of the babies both in the group with GDM patients (r: −0.785; P=0.001) and in the control group (r: −0.749; P=0.001).

Conclusions: In pregnant women with GDM, umbilical cord ghrelin concentrations are closely related to the birth weights of the babies. Ghrelin presumably may be among the factors influencing foetal development potentially with its GH stimulating effects or by means of other mechanisms.
