Background/objectives: Individuals born small-for-gestational age (SGA), especially those who experience postnatal catch-up growth, are at increased risk for developing endocrine-metabolic abnormalities before puberty. In adults, brown adipose tissue (BAT) has been associated with protection against metabolic disorders, such as obesity, type 2 diabetes and dyslipidaemia. Here, we assessed for the first time whether BAT activation differs between prepubertal children born SGA o...

Circulating Growth-and-Differentiation Factor-15 in Early Life: Relation to Prenatal and Postnatal Size

Díaz Marta , Campderrós Laura , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Growth-and-differentiation factor-15 (GDF15) is a regulator of energy homeostasis, and is used as biomarker of several pathological states.Objectives: To assess longitudinally GDF15 concentrations in a cohort of infants born either appropriate- (AGA, n=70) or small-for-gestational-age (SGA, n=33), the latter known to be at increased risk for central adiposity and metabolic alteration...

Circulating Concentrations of Fibroblast Growth Factor 21 are Undetectable in Human Infants at Term Birth and Surge within Hours After Birth

Sanchez-Infantes David , Gallego-Escudero Jose Miguel , Cereijo Ruben , Diaz Marta , Aragones Gemma , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

Background: In rodents, fibroblast growth factor 21 (FGF21), an endocrine member of the FGF family, is mainly produced in the liver and promotes glucose oxidation in several tissues; the circulating concentrations of FGF21 rise shortly after birth. In the human, the ontogeny of circulating FGF21 is essentially unknown.Objective and hypotheses: To assess whether there is also a neonatal surge of circulating FGF21 concen...

Circulating GDF15 Concentrations in Girls with Low Birth Weight and Precocious Pubarche: Effects of Prolonged Metformin Treatment

Díaz Marta , Carreras-Badosa Gemma , Bassols Judit , de Zegher Francis , López- Bermejo Abel , Villarroya Francesc , Ibáñez Lourdes

Background: Low birth weight (LBW) followed by a rapid postnatal catch-up in weight predisposes individuals to a central distribution of body fat, which is reverted by metformin. Growth-and-differentiation-factor-15 (GDF15) plays an important role in the regulation of energy homeostasis, reducing food intake and lowering body weight. We aimed to assess whether GDF15 concentrations are raised by long-term metformin treatment in LBW/catch-up girls with precociou...
