Gene Chimeras Involving CYP21A2 and TNXB Genes in Spanish Patients with Congenital Adrenal Hyperplasia (CAH)

Martínez Figueras Laura , Escribano Muñoz Arancha , Carcavilla Atilano , Berthold Laura , Llorente Martín Elena , Arriba Domènech María , Ezquieta Zubicaray Begoña

Background-Aim: Gene rearrangements between CYP21A2, TNXB and their homologous pseudogenes (CYP21A1P,TNXA) result in chimeric genes, responsible for the CAHX syndrome. CAHX patients show CAH and Ehlers-Danlos syndrome (EDS) symptoms. Three CAHX chimeras with different clinical severity are described: CH1 (including 120bp deletion in exon 35), CH2 and CH3. The small size and few series reported so far warrant further studies ...

Increased Basal Levels of 17-Hydroxyprogesterone In The Covid ERA: Must We Change The Cut-Off Point To Request Acth Test?

Laura Bertholt Zuber M. , Alonso Rubio Pablo , Palenzuela Revuelta Inmaculada , Pozas Mariscal Sara , Lavín Gómez Bernardo , Teresa Garcia Unzueta M.

Background: 17-hydroxyprogesterone (17-OHP) basal levels greater than 2ng/ml has been related to the need to request an ACTH test to dismiss non-classic congenital adrenal hyperplasia. We have seen an increase in baseline levels in 2021 compared to 2020.Objectives: To determine how many of the tests that were requested due to a high basal 17-OHP value, were positive. Assess the need to modify the cut-off points to reques...

Screening for disordered eating behaviours and associated factors in children and adolescents with type 1 diabetes

Barsal Çetiner Ebru , Donbaloğlu Zeynep , Singin Berna , Aydın Behram Bilge , Bedel Aynur , Parlak Mesut , Ünver Tuhan Hale

Introduction and Purpose: Patients with type 1 diabetes mellitus must be extremely concerned with what they eat and their insulin dose as part of their treatment. Therefore, the risk of eating disorders increases in this patient group. This study, it was aimed to determine the disordered eating behaviors of patients with Type 1 DM and to evaluate the results of the general demographic characteristics, diabetes care behaviors, and quality of life scale that whi...

Introduction: Chronic inflammation is closely associated with metabolic disorders such as obesity, insulin resistance and Type 2 DM, and is dependent on abnormal cytokine production and activation of inflammatory signaling pathways. Adipose tissue is a metabolically active organ that can be a source of low-grade chronic inflammation in obese individuals. Our aim in this study; to determine whether there are changes in proinflammatory and antiinflammatory cytok...

The Impact of Acute Exercise on 12,13-Dihydroxy-9Z-Octadecenoic Acid (12,13-DiHOME) Levels in Male Adolescents with Obesity

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...

Positive impact of the TuiTek® patient support programme on caregivers of patients receiving treatment for growth hormone deficiency in Argentina

Sordelli Micaela , Debicki Matías , Gonzalez Judit , María Sosa Ana , Hernán Cejas Leopoldo , Ginaca Romina , Jheeta Amrit , Malik Sumaira , Koledova Ekaterina , Assefi Aria

Background: Good adherence to recombinant human growth hormone (r-hGH) is crucial to achieve optimal growth outcomes in children with GH deficiency (GHD). Controlling factors that negatively impact adherence is difficult in clinical practice. In order to obtain a better understanding of caregiver behaviour, an Argentinian patient support programme (PSP) implemented TuiTek®, a personalised programme comprising behavioural change training, call guides...

Analysis of Hypothalamic Metabolic Circuits after Normalization of Body Weight in Mice That Had Been Obese Due to High Fat Diet Intake

Guerra-Cantera Santiago , Frago Laura , Ros Purificación , Canelles Sandra , Díaz Francisca , Freire-Regatillo Alejandra , Torrecilla-Parra Marta Marta , Argente Jesús , Chowen Julie A.

The obesity epidemic continues to be a dramatic problem in the developed world despite attempts to curtail its rise. Reducing energy intake and/or increasing energy expenditure can result in weight loss; however, if one returns to their poor lifestyle habits the previous weight is not only recuperated, but often surpassed.We hypothesized that although a normal body weight may be achieved, the hypothalamic circuits controlling appetite and energy expendit...

Peripheral and Hypothalamic Alterations in the Insulin-like Growth Factor (IGF) System in Response to High Fat Diet-induced Weight Gain

Guerra-Cantera Santiago , Díaz Francisca , Ros Purificación , Freire-Regatillo Alejandra , Torrecilla-Parra Marta , Barrios Vicente , Frago Laura , Chowen Julie A. , Argente Jesús

The insulin-like growth factor (IGF) system is fundamental for physiological processes such as growth and metabolism. In addition, in the brain it regulates glucose metabolism and neuroprotection. The IGF axis can be altered by nutritional status, but little is known regarding the effects of specific dietary components on this system.Our aim was to examine how high-fat diet (HFD) and low-fat/high sucrose diet (LFHSD) intake affect the central and circula...

PAPP-A2 Deficiency Results in Sex-Dependent Modifications in Hypothalamic Regulation of Energy Homeostasis

Rivera Patricia , Vargas Antonio , Bonsón Javier , Christians Julian , Rodríguez de Fonseca Fernando , Chowen Julie , Suárez Juan , Argente Jesús

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...

Plasma Tocopherols and Carotenes are Decreased in Spanish Children and Adolescents with Insulin Resistance, Independently of Obesity

Rupérez Azahara I. , Lozano Gloria Bueno , Leis Rosaura , Gil-Campos Mercedes , Gil Ángel , Moreno Luis A. , Mesa María D. , Aguilera Concepción M.

Introduction: Childhood obesity and insulin resistance (IR) are rising in prevalence, increasing the future adults' cardio-metabolic risk. One of the potential mechanisms behind these alterations is oxidative stress, fruit of increased free radical production and diminished antioxidant defense. Although low plasma vitamin concentrations and oxidative stress have been observed to be associated with obesity in adults and children, their association with IR i...
