Abstract OBJECTIVE: The objective of this study was to investigate possible alterations in circulating levels of the adipocytokine visfatin in intrauterine growth-restricted and normal pregnancies, given that these groups differ considerably in fetal nutrition, body fat mass, and metabolic/endocrine mechanisms. METHODS: Serum visfatin levels were prospectively measured by enzyme immunoassay in 40 mothers and their 40 singleton term fetuses and neonates on postnatal days 1 and 4. Twenty neonates had intrauterine growth restriction (birth weight < or = 3rd customized centile, adjusted for parameters that influence growth potential), and 20 were appropriate for gestational age. RESULTS: Circulating maternal visfatin levels were significantly elevated in pregnancies with intrauterine growth restriction compared with control pregnancies with appropriate-for-gestational-age infants and negatively correlated with customized centiles in the group with intrauterine growth restriction. Postnatal day-1 and -4 visfatin levels were significantly higher in neonates with intrauterine growth restriction compared with neonates who were appropriate for gestational age. Postnatal-day-1 prefeeding insulin levels were significantly lower in neonates with intrauterine growth restriction. CONCLUSIONS: Pathologic conditions in pregnancy that lead to intrauterine growth restriction could be responsible for elevated maternal visfatin levels. Higher visfatin levels in neonates with intrauterine growth restriction may serve as an early marker with prognostic value for later development of insulin resistance or type 2 diabetes, whereas lower insulin levels may indicate reduced beta-cell mass and/or impaired beta-cell function.
