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...

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...

Effects of Bifidobacterium animalis subsp. lactis on Children with Prader-Willi Syndrome: A Randomized, Double-Blind, Placebo-Controlled, Crossover Trial

Ramon-Krauel Marta , Amat-Bou Montse , García-Rivera Sonika , Corripio Raquel , Ibáñez Lourdes , Lerin Carles

The gut microbiome has recently emerged as a major contributor to obesity and metabolic disease. Specifically, Bifidobacterium animalis sups. lactis (BAL) has shown promise for obesity treatment in human subjects, improving body composition and metabolic health. Moreover, tryptophan metabolism, a crucial regulator of satiety mechanisms and anxiety, is a main target of BAL. Given that clinical manifestations of Prader-Willi syndrome (PWS) include hyperphagia, ...

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...

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...

DNA Methylation Signatures in Placenta and Umbilical Cord: Association with Maternal Obesity

Background and Objectives: Offspring born to obese mothers are at an increased risk of chronic disease including type 2 diabetes (T2D), obesity, hypertension, cardiovascular disease (CVD), non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease (CKD). This metabolic programming is produced, in part, by epigenetic changes such us DNA methylation. We postulated that obesity exposure impacts the offspring's methylome and used an epigenomic approa...

Dysregulated Gene Expression Profile in Visceral Adipose Tissue of Juvenile Wistar Rats with Catch-Up Growth: Association with Fat Expansion and Metabolic Parameters

Lizárraga-Mollinedo Esther , Carreras-Badosa Gemma , Remesar Xavier , Xargay-Torrent Silvia , Mas-Parés Berta , Prats-Puig Anna , de Zegher Francis , Ibáñez Lourdes , López-Bermejo Abel , Bassols Judit

Background: Accelerated catch-up growth following intrauterine growth restriction increases the risk of developing visceral adiposity and metabolic syndrome. Animal models of growth restriction during gestation have been developed as a powerful tool to provide insight into the underlying molecular mechanisms thereof.Objective: To analyze the patterns of gene expression in the retroperitoneal adipose tissue of rats with i...

Circulating Insulin-Like Growth Factor-I Independently Predicts Blood Pressure in Apparently Healthy Children

Xargay-Torrent Sílvia , Dorado-Ceballos Estefanía , Benavides-Boixader Anna , Lizárraga-Mollinedo Esther , Mas-Parés Berta , Montesinos-Costa Mercè , Zegher Francis de , Ibáñez Lourdes , Bassols Judit , López-Bermejo Abel

Background and Objectives: In adults, discordant associations exist between insulin-like growth factor-I (IGF-I) and blood pressure with scarce reports in apparently healthy children. IGF-I levels increase during puberty in parallel to calcium and phosphorus levels. In this context, our aim is to study the association between IGF-I and blood pressure in apparently healthy children, together with the interaction of the serum calcium-phosphorus product (Ca*P...
