OBJECTIVE: To investigate circulating concentrations of human fetuin-A (important fetal glycoprotein, involved in vascular pathology and bone metabolism) in mothers, fetuses and neonates from intrauterine-growth-restricted (IUGR, associated with low bone mass at birth and metabolic syndrome in adult life) and appropriate-for-gestational-age (AGA) pregnancies. METHODS: Serum fetuin-A concentrations were prospectively measured in 40 mothers, the doubly-clamped umbilical cords (representing fetal state) and their 20 IUGR and 20 AGA full-term neonates on postnatal day 1 (N1) and 4 (N4). RESULTS: No significant differences in fetuin-A concentrations were observed between groups, or between maternal, fetal and neonatal samples in both groups. In the AGA group, maternal fetuin-A concentrations positively correlated with fetal and N1 ones (r = 0.599, p = 0.005 and r = 0.469, p = 0.037, respectively). In the IUGR group, maternal fetuin-A concentrations positively correlated with N4 ones (r = 0.541, p = 0.014). CONCLUSION: Serum fetuin-A concentrations do not differ between IUGR cases and AGA controls. Maternal and fetal fetuin-A concentrations are similar and positively correlated, indicating the likelihood of passive transplacental transfer of this substance.
