Introduction: Gonadotoxicity associated with chemotherapy of hematologic malignancies has been described mainly in adults, focused on the sensitivity of germ cells. Little attention has been placed on Sertoli cells during childhood and puberty, even though Sertoli cell development is essential for adult spermatogenesis.Objective: To assess function of the pituitary-testicular axis, with emphasis on Sertoli cell function,...

RNPC3 Mutations Associate Prolactin Deficiency and Ovarian Insufficiency, Expanding the Phenotype Beyond Isolated Growth Hormone Deficiency Type V (MIM#618860)

Martos-Moreno Gabriel Á. , Travieso-Suárez Lourdes , Pozo Jesús , Chowen Julie , Pérez-Jurado Luis A. , Argente Jesús

Background: The first three children reported to have biallelic mutations in RNPC3 presented with growth hormone (GH) deficiency and pituitary hypoplasia (MIM#618860). RNPC3 codes for a minor spliceosome protein required for U11/U12 small nuclear ribonucleoprotein formation and splicing of U12-type introns. The underlying mechanism causing GH deficiency in these patients is not fully understood. Moreover, whether the association of further ho...

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...

Changes in objectively measured physical activity after 2-year lifestyle intervention in pediatric patients with abdominal obesity

Ojeda-Rodriguez Ana , Morell-Azanza Lydia , Luis Leon Jose , Macias Maria , Chueca Maria , Marti Amelia , Cristina Azcona-Sanjulian Maria ,

Introduction: it has been widely demonstrated that high physical activity (PA) levels prevent obesity development. The practice of moderate, regular PA reduces abdominal obesity, hypertension, insulin resistance, dyslipidemia and improves risk factors for obesity-related comorbidities (e.g. diabetes or cardiovascular diseases) independently of weight loss. However, in the childhood population, where sedentary behavior has increased in recent decades, few studi...

Adherence to Diabetes Care in Children and Adolescents with Type 1 Diabetes Mellitus in Spain: Results from the Chrystal Study

Siguero Juan Pedro Lopez , Vazquez Luis Alberto , Villoro Renata , Jiang Dingfeng , Merino Maria , Reviriego Jesus , Perez-Nieves Magaly

Background: CHRYSTAL (Costs and Health Related qualitY of life Study for Type 1 diAbetes mellitus pediatric patients in Spain) is an observational study conducted in 2014 on a representative sample of 275 patients aged 1-17 years with Type 1 Diabetes Mellitus (T1DM) in Spain.Objective and hypotheses: One of the objectives of the study was to describe the adherence to diabetes care using the Self Care Inventory (SCI), and to compare results by HbA1c level...

Ovarian AMH production is transiently affected in pubertal and prepubertal girls with acute lymphoblastic leukaemia and non-Hodgkin lymphoma receiving chemotherapy: a prospective, longitudinal study.

Gabriela , Gryngarten Mirta , Soria Marcela , Moran Lorena , Ferraro Cristina , Freire Analia , Bergada Ignacio , Drelichman Guillermo , Aversa Luis , Rey Rodolfo A. , Grinspon Romina P. ,

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Clinical and Molecular Characterization of One Nr5a1 Gene Mutation Found in a Patient WITH 46, XY DSD

Vela Amaya , Lapiscina Idoia Martinez De , Nanclares Gustavo Perez De , Amaia Rodriguez , Rica Itxaso , Castano Luis , Grau Gema

Introduction: Steroidogenic factor-1 (SF1), encoded by the NR5A1 gene, regulates several genes involved in male sexual determination, such as SOX9 and AMH, cholesterol mobilization and synthesis of a number of steroidogenic enzymes, like 3βHSD, and androgen biosynthesis, like INSL3. Mutations in NR5A1 have been associated to a broad phenotypic spectrum in 46, XY subjects, including pure gonadal dysgenesis, infertility, anorchia...

A Multiplatform Non-targeted Metabolomics Approach to Investigate Insulin Resistance Associated to Obesity in Childhood

Mastrangelo Annalaura , Martos-Moreno Gabriel , Garcia Antonia , Ruperez Francisco , Chowen Julie , Perez-Jurado Luis , Barbas Coral , Argente Jesus

Background: Childhood obesity is often associated with insulin resistance (IR), which is a key risk factor for the development of comorbidities. The etiologic relation between insulin resistance and obesity is still not completely understood.Objective: In this study a multiplatform metabolomics approach was applied for the first time to elucidate the metabolic alterations in obese children with or without IR. Metabolomics is the revolutionary strategy of...

Prevalence of Autoimmunity in Relatives of Patients with Type 1 Diabetes: Time to The Clinical Onset of Diabetes and Associated Risk Factors

Marcelo Irene , Urrutia Ines , Calvo Begoña , Martinez Rosa , Saso Laura , Castaño Luis , Rica Itxaso , Group Collaborative

Introduction: Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the presence of pancreatic-autoantibodies, which are diagnostic biomarkers. The detection of autoantibodies in first-degree relatives of patients with T1D is considered a risk factor for developing the disease; however, there is little information on how long it takes from the detection of autoimmunity to the clinical onset of T1D.Objectives:</st...

Introduction: Physical activity (PA) is one of the treatments to promote weight loss in children with obesity. The WHO advices to perform moderate to vigorous (MV) PA during 60-min daily. It is necessary to measure the effect of increasing PA and the adherence to therapy.Aims: To evaluate PA using accelerometry at the onset and after 8 weeks of treatment with nutritional intervention and increase in PA.Patients, material and method...
