Recognition of a Sequence: More Growth before Birth, Longer Telomeres at Birth, More Lean Mass after Birth

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

Background: Telomere length at birth is a major determinant of telomere length in late adulthood. However, the prenatal setting of telomere length is poorly understood. Individuals born large from non-diabetic mothers are at lower risk for later-life disorders than those born small, a feature of their longer health span being a higher lean mass that provides more muscle strength and that is already present in infancy.Objective, hypotheses & methods: ...

Polycystic Ovary Syndrome in Adolescent Girls:Towards a Treatment Focusing on Ectopic Fat

Ibáñez Lourdes , de Zegher Francis

Polycystic ovary syndrome is the most common cause of hirsutism and menstrual irregularity in adolescent girls and young women. It is often accompanied by obesity and insulin resistance and is associated to lifelong co-morbidities, including subfertility, type 2 diabetes, non-alcoholic fatty liver disease, pre-menopausal cancer, depression, low health-related Qol, and pregnancy and offspring complications. PCOS in adolescent girls is commonly driven by fat excess in subcutaneo...

Pituitary tuberculosis and hypothalamic obesity can be reversed by prolonged anti-tuberculosis treatment

Rochtus Anne , Lagae Lieven , Vermeulen Francois , de Zegher Francis

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...

Toward a Simple Marker of Hepato-Visceral Adiposity and Insulin Resistance:The Z-Score Change from Weight-at-Birth to BMI-in-Childhood

Malpique Rita , de Zegher Francis , Garcia-Beltran Cristina , Ibáñez Lourdes

Insulin resistance and hepato-visceral (central) fat excess are thought to contribute to an earlier timing of adrenarche/pubarche and puberty/menarche; this earlier timing in turn relates often to a mismatch between pre- and postnatal weight gain, which can be estimated by calculating the Z-score change from birth weight (BW) to body mass index (BMI) in childhood. We tested the hypothesis that this calculation may serve as a proxy of insulin resistance and hepato-visceral adip...

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...

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...

Further Expansion of the CHARGE Geno-Phenotype: A Girl with a Novel Deletion of CHD7 and with the Combination of Hypogonadotropic Hypogonadism and Agenesis of Internal Genitalia

Reynaert Nele , de Zegher Francis , Devriendt Koenraad , Francois Inge , Beckers Dominique , Casteels Kristina

Background: CHARGE syndrome is a variable entity. Clinical diagnosis is based on the Blake-Verloes criteria and can be confirmed by identifying a mutation in CHD7. Hypoplasia of the genitalia is a common feature and is most often attributable to hypogonadotropic hypogonadism which is described in 81% of the males and 93% of the female patients. Other genital anomalies are rare. Combined agenesis of the uterus and ovaries is so far only reported in one patient with sus...

Circulating miR-451a: A Biomarker to Guide Diagnosis and Treatment of Polycystic Ovary Syndrome in Adolescent Girls

Díaz Marta , Bassols Judit , López-Bermejo Abel , de Zegher Francis , Ibáñez Lourdes

Polycystic ovary syndrome (PCOS) is a prevalent disorder in adolescent girls, commonly driven by hepato-visceral fat excess, usually presenting with hirsutism and menstrual irregularity, and often followed by subfertility and type 2 diabetes.We studied the miRNA profile of adolescent girls with PCOS, and the effects of randomized treatment with an oral contraceptive (OC) or with spironolactone-pioglitazone-metformin (SPIOMET, aiming at loss of hepato-vis...
