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...

Low-dose pioglitazone for polycystic ovary syndrome in adolescent girls:differential fat-mass redistribution by HOTAIR rs1443512 genotype

de Zegher Francis , Diaz Marta , Ibañez Lourdes

Introduction: Adolescent polycystic ovary syndrome (PCOS) is characterized by androgen excess and oligo-amenorrhea, and often results from ectopic lipid storage due to a mismatch between early adipogenesis and later lipogenesis. Endogenous HOTAIR and exogenous pioglitazone are enhancers of subcutaneous adipogenesis, particularly in the gluteofemoral region. The A allele of HOTAIR rs1443512 is an equivalent of a natural knock-down and is thus a candidate to inf...

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...

Identification of Three Novel GLI2 Gene Variants Associated with Hypopituitarism

Castro-Feijoo Lidia , Cabanas Paloma , Barreiro Jesus , Silva Paula , Couce M Luz , Pombo Manuel , Loidi Lourdes

GLI2 is a downstream transcription factor in Sonic Hedgehog signaling, acting early in ventral forebrain and pituitary development. Heterozygous GLI2 mutations have been reported in patients with isolated or combined pituitary hormone deficiency (CPHD).Objective: Study of genetic etiology of the hypopituitarism and identification of the genetic alteration in GLI2 gene.Methodology: Molecular study: Search for varia...

The Growzen™ buddy smartphone application shows positive findings on adherence in Argentinian patients receiving growth hormone therapy for growth disorders

van Dommelen Paula , Arnaud Lilian , Assefi Aria , Lourdes Crespo Maria , Koledova Ekaterina

Background: Digital health solutions, such as the Growzen™ buddy smartphone application (app), can facilitate adherence to recombinant human growth hormone (r-hGH) treatment for patients with growth disorders. The app alerts patients when it’s time for an injection and allows patients and their caregivers to self-monitor growth, to build a routine and improve adherence. The app also contains educational resources to empower patients to be active in...

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...

Osteogenesis Imperfecta: Genetic Evaluation

Castro-Feijoo Lidia , de la Torre Marina , Cabanas Paloma , Pino Jesus , Pombo Manuel , Barreiro Jesus , Loidi Lourdes

Osteogenesis imperfecta (OI) is a rare, hereditary bone dysplasia with a broad clinical spectrum that includes skeletal and extra-skeletal manifestations. It is genetically heterogeneous and there are multiple described mutations that explain the clinical variability of this entity and make it difficult to establish a genotype-phenotype correlation.Objectives: To evaluate the clinical and genetic characteristics of the patient with OI.</...

Genetic Study of Osteogenesis Imperfecta: Two Novel Mutations in COL1A1 and COL1A2

Castro-Feijoo Lidia , Loidi Lourdes , Quiroga Nuria , Cabanas Paloma , Heredia Claudia , Leis Rosaura , Barros Francisco , Pombo Manuel , Barreiro Jesus

Background: Osteogenesis imperfecta (OI) is a clinically and genetically heterogeneous rare disorder characterized by variable symptoms including predisposition to fractures. OI has been associated with mutations affecting the synthesis of type I collagen. However, the new technologies have permitted the identification of other responsible genes which are in the collagen metabolic pathway, while others are not.Objective: Characterize the genotype of pati...

Circulating Progranulin in Human Infants: Relation to Prenatal Growth and Early Postnatal Nutrition

Díaz Marta , Mestres-Arenas Alberto , López-Bermejo Abel , de Zegher Francis , Villarroya Francesc , Ibáñez Lourdes

Background: Progranulin (PGRN) displays pleiotropic biological functions including on early embryogenesis, cell proliferation, lysosomal or neuronal functioning and wound repair, and has been proposed as a biomarker for metabolic diseases. Increased PGRN levels have been reported in type 2 diabetes, nonalcoholic fatty liver disease and in preeclampsia associated to placental dysfunction. However, the ontogeny of PGRN concentrations and the potential value of P...
