Replacement of the Neonatal Leptin Surge During Maternal Deprivation Normalizes Some Endocrine Parameters but Exacerbates Others

Mela Virginia , Lopez-Rodriguez Alvaro , Penasco Sara , Barrios Vicente , Argente Jesus , Viveros Maria-Paz , Chowen Julie A

Introduction: Maternal deprivation (MD) during neonatal life has diverse long-term effects, including modification of metabolism. Some of these effects are sexually dimorphic. We have previously reported that MD in rats blocks the physiological neonatal leptin surge, which could underlie the long-term metabolic changes.Hypothesis: We hypothesized that replacement of leptin during MD would normalize long-term endocrine changes.Metho...

Pituitary Stalk Interruption Syndrome: a Sequential Manner to Gain Pituitary Hormone Deficiencies with Still Unknown Molecular Basis

Jerez Elena , Echeverria Gabriela , Munoz-Calvo Teresa , Pozo-Roman Jesus , Martos-Moreno Gabriel , Argente Jesus

Background: Pituitary stalk interruption syndrome (PSIS) is characterized by the absence of the pituitary stalk, pituitary hypoplasia and an ectopic posterior pituitary.Objective: We aimed to retrospectively analyze the clinical, auxological, biochemical, and radiological findings in Spanish patients with PSIS.Patients and results: Of 27 patients, 25% were female and 75% male. Perinatal features, auxological and endocrine study at ...

Intrauterine Growth Restriction is Associated with Greater Severity in Childhood Obesity-Associated Metabolic Impairment and Poorer Adult Height Prediction

Gonzalez-Leal Rocio , Martinez-Villanueva Julian , Argente Jesus , Martos-Moreno Gabriel A.

Background: Intrauterine growth influences the risk of childhood obesity and its associated metabolic derangement.Objective and hypotheses: To investigate the effect of intrauterine growth (as shown by newborn anthropometry) on physical and metabolic features in obese children and adolescents.Method: A retrospective study of 1049 obese children and adolescents (46.8% females/53.2% males; age: 10.31±3.23 years; BMI: +4.00±...

Physical and Metabolic Evolution of Obese Children and Adolescents after the Attainment of Intense Weight Reduction

Martos-Moreno Gabriel A , Martinez-Villanueva Julian , Gonzalez-Leal Rocio , Argente Jesus

Background: Despite the lack of drugs, conservative management of childhood obesity allows for considerable weight reduction.Objective and hypotheses: i) To evaluate anthropometric and metabolic changes in obese children after intense weight loss. ii) To analyze the influence of the amount of weight loss and the time spent to attain it on the observed changes. iii) To investigate BMI evolution during the first 3 years after weight reduction.<p class=...

Rare heterozygous variants in genes of the leptin-melanocortin satiety pathway contribute to childhood obesity

Martos-Moreno Gabriel A. , Garcia-Rastrilla Rut , Martin-Rivada Alvaro , Perez-Jurado Luis A. , Argente Jesus ,

Background: The central melanocortin system is highly involved in the control of energy metabolism, receiving and integrating numerous metabolic signals, such as leptin, and biallelic mutations in several genes of the pathway have been reported in severe obesity. However, whether and how heterozygous rare sequence variants (hetRSVs) in genes of this satiety pathway contribute to the development of obesity is poorly explored.Objec...

Inflammation associated to body composition in European prepubertal children: Results from the IDEFICS study

Argente Pilar , Esther Gonzalez , Intemann Timm , Moreno Luis , Molnar Denes , Kaprio Jaakko , Russo Paola ,

Background: Obesity is characterised by excessive fat accumulation coursing with a chronic mild inflammatory state, with adipose tissue (AT) being the main site of increased systemic cytokine production. Increased adiposity early in life is the main risk factor for cardiometabolic disorders later in life, with the abnormal accumulation of lipids in AT leading to the production of pro-inflammatory cytokines. Inflammatory process that involves metabolic and card...

Endocrinological assessment in patients with fanconi anemia

Corredor-Andres Beatriz , Martin-Rivada Alvaro , Zubicaray Josune , Barrios Vicente , Sevilla Julian , Argente Jesus ,

Introduction: Fanconi anemia (FA) is a rare genetic disease that presents with aplastic anemia. Around 60% have short stature (SST), with a mean height of -2.2 SD. However, studies assessing the etiology of SST not having reached relevant conclusions.Aim: Our aim was to evaluate the clinical features and endocrine status in relationship to SST in patients with FA.Methods and Patients: A cross-secti...

Clinical Evolution After A 24 Month Nutritional Intervention Based on Carbohydrate Restriction in Adolescents with Obesity

González-Leal Rocío , María Andrés Esteban Eva , Argente Jesús , Ángel Martos-Moreno Gabriel

Introduction: Carbohydrate restriction (CH-R) in adolescents with obesity results in faster BMI reduction and glucose metabolism improvement than diets with normal carbohydrate proportion, without a higher weight regain in the short term. However, data on weight and metabolic trajectories of these patients after a more prolonged follow-up are sparse.Objectives: To evaluate metabolic and body composition evolution during ...

Identification of the First Obesity-Associated Mutations in Human Mesoderm-Specific Transcript (MEST) Result in Protein Overexpression, Adipocyte Hypertrophy and a Reduction in Adipocyte Mitochondrial Area

Suarez Juan , Martos-Moreno Gabriel , Rivera Patricia , Serra-Juhe Clara , Chowen Julie , Perez-Jurado Luis , Argente Jesus

Background: Mesoderm-specific transcript (MEST) is an epoxide α/β-hydrolase protein with catalytic activity that is determinant for the development of adipocytes. The MEST gene is an imprinted gene transcribed only from the paternal allele. Although the mechanism by which MEST overexpression augments fat accumulation and storage in adipocytes has not been fully elucidated, frequent subcellular contacts between MEST-positive endoplasmic reticulum, mi...

Background: The approach to clinical management of Graves’ disease (GD) is debatable.Objective: This study aimed to identify predictors of remission in pediatric GD.Methods: A longitudinal study of 36 children and adolescents with Graves’ disease followed from 1997 to 2017 at a single pediatric tertiary hospital was performed. Clinical and biochemical parameters, including comorbidities, treatment with anti-thyroid drugs ...
