Normalization of Ovulation Rate in Adolescent Girls with Hyperinsulinemic Androgen Excess

Ibanez Lourdes , del Rio Luis , Diaz Marta , Sebastiani Giorgia , Lopez-Bermejo Abel , de Zegher Francis

Background: Oligo-ovulatory androgen excess in women (polycystic ovary syndrome (PCOS) by NIH definition) is a major cause of subfertility and relates to hepatic steatosis, independently of obesity.Objective: To test whether early treatment of PCOS affects subsequent ovulation rate.Method: Adolescent girls with hyperinsulinemic androgen excess – a subgroup of PCOS – (mean age 16 year; BMI 23.7 kg/m2) randomly r...

Placental and Cord Blood DNA Methylation Profiling in Small-for-Gestational-Age Newborns from Uncomplicated Pregnancies: Relationship to Prenatal Growth and Postnatal Body Composition

Diaz Marta , Garcia Cristina , Sebastiani Giorgia , Garcia Francesc , Lopez-Bermejo Abel , Ibanez Lourdes

Background: Fetal growth is partly regulated by epigenetic factors, such as DNA methylation. Altered methylation status in placental genes relates to gestational diabetes, preeclampsia and prematurity. However, the epigenetic mechanisms underlying fetal growth restraint in uncomplicated pregnancies remain unknown.Objective and hypotheses: We aimed at identifying new candidate genes related to fetal growth, by assessing DNA methylation profiling in placen...

Circulating GLP-1 in Infants Born Small-for-Gestational-Age: Breast-Feeding Vs Formula-Feeding

Diaz Marta , Bassols Judit , Sebastiani Giorgia , Lopez-Bermejo Abel , Ibanez Lourdes , de Zegher Francis

Background: Prenatal growth restraint associates with risk for later diabetes particularly if such restraint is followed by postnatal formula-feeding (FOF) rather than breast-feeding (BRF). Circulating incretins can influence the neonatal programming of hypothalamic setpoints for appetite and energy expenditure, and are thus candidate mediators of the long-term effects exerted by early nutrition.Objective, hypotheses and method: We have tested this conce...

The Sequence of Prenatal Growth Restraint and Postnatal Catch-Up Growth Leads to a Thicker Intima Media and More Pre-Peritoneal and Hepatic Fat by Age 3-6 Years

Sebastiani Giorgia , Diaz Marta , Bassols Judit , Lopez-Bermejo Abel , De Zegher Francis , Ibanez Lourdes

Background: Infants born small-for-gestational age (SGA) who develop postnatal weight catch-up are at risk for insulin resistance, central adiposity and cardiovascular disease in later life, even in the absence of overweight.Objective and hypotheses: In young (age 3–6 years) non-obese SGA children, we assessed arterial health by intima-media thickness (IMT) and abdominal fat distribution (subcutaneous, visceral, pre-peritoneal and hepatic components...

Oral Contraception Vs Low-Dose Pioglitazone-Spironolactone-Metformin for Adolescent Girls with Hyperinsulinaemic Androgen Excess: On-Treatment Divergences

Ibanez Lourdes , Diaz Marta , Sebastiani Giorgia , Lopez-Bermejo Abel , de Zegher Francis

Background: Hyperinsulinemic androgen excess is the most common cause of hirsutism, acne, seborrhea and menstrual irregularity in adolescent girls. The ovarian androgen excess originates most often from an absolute or relative excess of fat (in adipose tissue and in organs such as the liver) and from the ensuing elevations in insulinaemia and gonadotropin secretion. There is no approved therapy for androgen excess in adolescent girls. The prime recommendation is to reduce body...

Brown Adipose Tissue in Prepubertal Children: Associations with Sex and With the Sequence of Prenatal Growth Restraint and Postnatal Catch-up

Malpique Rita , Gallego-Escuredo Jose Miguel , Sebastiani Giorgia , Villarroya Joan , Lopez-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibanez Lourdes

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...

Cardiac and Vascular Assessments in Small- vs Appropriate-for-Gestational-Age Infants at Ages 1 and 2 Years

Garcia-Beltran Cristina , Sebastiani Giorgia , Pie Stella , Guerra Alberto , Lopez-Bermejo Abel , de Zegher Francis , Roses Ferran , Ibanez Lourdes

Background: Children born small-for-gestational age (SGA), especially those who experience spontaneous postnatal catch-up growth, are at increased risk for developing insulin resistance, central adiposity and cardiovascular abnormalities later in life. By age 3-6 years, SGA children have a broader aortic and carotid intima media thickness (aIMT and cIMT) which are markers of preclinical atherosclerosis.Objective: To assess longitudinally – at age 12...

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...
