Abstract

Under conditions of non-optimal supply of nutrients, maternal diet during gestation can alter the balance between anabolic and catabolic pathways of fetus and triggers an effect of programming to the metabolic syndrome. Metabolomics is an analytical technique that has been recently attracting increasing interest for the identification of biomarkers of dietary exposure. In this study, a NMR-based metabolomic approach was employed for an explorative analysis of the time-related urinary metabolic profiles of three groups of newborns receiving a different fetal nutrition: adequate for gestational age (AGA), with intrauterine growth retardation (IUGR), and large for gestational age (LGA). Urine samples were collected over the first week of life. Application of Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) evidenced similar time-related modifications in the metabolic profiles of the three classes of infants, consisting mainly of changes in levels of taurine, creatinine, betaine, and glycine. Furthermore, alterations in the content of citrate and myo-inositol were found to be characteristic of IUGR and LGA, whole levels were higher with respect to controls, while higher contents of betaine and succinate were noted in AGA. Our results positively support the application of the metabolomic approach in the study of the metabolic pathways associated to fetal malnutrition.
