Large-Born Infants Switch from an Adipose to a Lean and Insulin-Sensitive State with Low Concentrations of Circulating Myostatin and Follistatin

Sebastiani Giorgia , Cruz Miriam Perez , Silva Marta Diaz , Roig Maria Dolores Gomez , Bermejo Abel Lopez , Toda Lourdes Ibanez , De Zegher Francis

Background: Muscle is key to glucose metabolism. Myogenesis is completed in early infancy, partly under the inhibitory control of myostatin, a myokine whose actions can be influenced by follistatin. Early lowering of myostatin actions is thus a potential strategy to reduce the risk for later diabetes.Objective and hypotheses: We performed a first screening of whether such lowering is among the natural mechanisms whereby some human infants augment their l...

Uric Acid and Risk for Atherosclerotic Disease Early in Life

Bassols Judit , Martinez-Calcerrada Jose-Maria , Prats-Puig Anna , Carreras-Badosa Gemma , Diaz-Roldan Ferran , Osiniri Ines , Riera-Perez Elena , de Zegher Francis , Ibanez Lourdes , Lopez-Bermejo Abel

Background: Increased uric acid is an independent risk factor for cardiovascular disease in obese adults and adolescents. The relationship between uric acid and atherosclerotic risk early in life is unknown.Objective and hypotheses: We investigated whether uric acid relates to carotid intima–media thickness (cIMT), a marker of preclinical atherosclerosis, in a rather large sample of school-age children and investigated the interaction of obesity sta...

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...

A New Case of Proopiomelanocortin Deficiency

Fuentes-Bolanos Noemi Auxiliadora , Madueno Francisco Jose Tinahones , Gonzalez Luis Castano , Gea Isabel Leiva , Ollero Maria Jose Martinez-Aedo , Lopez-Siguero Juan Pedro

Introduction: The proopiomelanocortin is a polypeptide of many biologically active peptides involved in many key functions which have not yet been clarified. The mutation in the gene encoding this polypeptide is associated with a clinical trials characterized by early-onset obesity, terciary adrenal insufficiency, and alteration of pigmentation. Eight cases with known genetic mutation have been published.Case report: Newborn male 27 days old from North A...

SHBG Integrates the Cardiovascular Risk and Metabolic Dysfunction of Gestational Obesity

Bassols Judit , Soriano-Rodriguez Pilar , Prats-Puig Anna , Carreras-Badosa Gemma , Miranda-Arce Miguel-Angel , Alvarez-Castano Elena , de Zegher Francis , Ibanez Lourdes , Lopez-Bermejo Abel

Background: Sex hormone-binding globulin (SHBG) is the major sex steroid carrier protein. Its production is negatively regulated by insulin and monosaccharides. The concentration of SHBG increases between 16 and 27 weeks gestation and is negatively associated with pre-gestational BMI and weight gain during pregnancy. The link of SHBG with cardiovascular risk is poorly understood.Objective and hypotheses: In obese pregnant women, we aimed to study the ass...

Absence of GH Signaling Induces Hypothalamic Inflammation that is Reversed in Response to a High Fat Diet

Baquedano Eva , Ruiz-Lopez Ana , Pardo-Barquin Elena , Gosney Elahu S , Herpy James , Chowen Julie A , Argente Jesus , Kopchick John J , Frago Laura M

Background: The GH/IGF1 axis has important roles in growth, metabolism, lipid profile and body composition. GH receptor disrupted mice (GHRKO mice) are resistant to the action of GH, thereby, GHRKO mice are dwarf, hypoinsulinemic, hypoglycemic and obese. Consumption of a high fat diet (HFD) induces inflammatory processes in a multitude of peripheral tissues, including hypothalamus.Objective and hypotheses: Our aim was to evaluate the effect of HFD intake...

Thyroid Function and Autoimmunity and Their Relation to Weight Status in Healthy Children and Adolescents

Garcia-Garcia Emilio , Galera-Martinez Rafael , Garcia-Escobar Iciar , Oliva-Perez Patricia , Gomez-Llorente Jose L. , Momblan Jeronimo , Vazquez-Lopez Maria A. , Perales Antonio Bonillo

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Autosomal-Dominant Hypocalcaemia, New Clinical Features

Gea Isabel Leiva , Fuentes-Bolanos Noemi Auxiliadora , Munoz-Garach Araceli , Gonzalez Luis Castano , Ollero Maria Jose Martinez-Aedo , Lopez-Siguero Juan Pedro

Introduction: The extracellular calcium-sensing receptor (CaSR) enables the parathyroid glands and other CaSR-expressing cells involved in calcium homeostasis to sense alterations in calcium serum concentrations. Mutations in the CASR gene may produce gain or loss in its activity. Activating mutations cause a hypocalcaemic syndrome of varying severity, as autosomal-dominant hypocalcaemia or Bartter’s syndrome.Case report: We describe a 6 months infa...

Background: Up to 50% SGA did not do a proper catch up (for over/under) and may have implications in size, metabolic, cardiovascular. Arises: epiSGA – PreMeb Project. Global approach to study.Objective: Create clinical cohort of SGA for monitoring, assessment catch-up, use GHRH requirements, environmental/social factors and variables influence on clinical, laboratory and metabolic profiles in order to progress in the knowledge of natural history.

Background: Although the theoretical impact of small in weight and/or size at birth (<2 SDS for EG) is 3–5% (3.5% in the Basque Country (source: Local Government) the socio-economic situation in our country has conditioned a change in its l although 50% at 2 years did not do a proper catch up (by excess or defect) with potential impact on future size and metabolic complications, cardiovascular require specific monitoring.Objective: To assess soc...
