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...

A pre-analytical challenge to determine estradiol in children: A monovette systematically causing increased estradiol-concentrations in LC-MS/MS analysis

Lamprecht Tabea , Kleber Michaela , Rothermel Juliane , Holterhus Paul-Martin , Kulle Alexandra ,

Introduction: In children, estradiol (E2) concentrations are 1000-times lower in comparison to their precursors, the androgens. Depending on sex, age, and pathology, plasma concentrations vary in a broad range. The sensitive and specific determination of E2 is a particular challenge in pediatric endocrinology. Here we report a female patient aged 12 6/12 years and Tanner stage B1 with a presumed diagnosis of ovarian insufficiency. She showed a very high E2 con...

Have a real increase in precocious and advanced puberty with COVID19? Retrospective observational analytical study in which we compared the incidence of first consultations made by early thelarchies between the months of March to December 2019 and between March and December 2020 at the Pediatric Endocrinology(PE)consultation in our hospital, and the increase in diagnosis of precocious puberty (PP)and advanced puberty (PA) in the cases evaluated for this reason, with the aim of...

Assessment of Hyperphagia in Patients with Monogenic Obesity

Zorn Stefanie , von Schnurbein Julia , Schirmer Melanie , Kohlsdorf Katja , Brandt Stephanie , Wabitsch Martin ,

Introduction: Besides an excessive, early-childhood weight gain, hyperphagia is the key symptom in patients with monogenic obesity. However, the assessment of hyperphagia is still challenging. Here, we applied the hyperphagia questionnaire developed for patients with Prader-Willi-Syndrome (PWS) to assess the severity of hyperphagia in patients with monogenic obesity.Methods: Pediatric patients with biallelic pathogenic l...

Design of a Phase 2, Double-Blind, Placebo-Controlled Trial of Setmelanotide in Patients With Genetic Variants in the Melanocortin-4 Receptor Pathway

Farooqi Sadaf , Wabitsch Martin , Chung Wendy , Ohayon Olga , Scimia Cecilia , Yuan Guojun , Shah Bhavik , Stewart Murray ,

Background: Rare genetic causes of obesity include variants in genes within the melanocortin-4 receptor (MC4R) pathway, a principal regulator of energy balance. Weight and hunger reductions following treatment with the MC4R agonist setmelanotide have been demonstrated in patients with obesity due to variants in multiple genes, including POMC, LEPR, SRC1, and SH2B1. We describe a trial design of setmelanotide in patients with addition...

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...

Liraglutide treatment in adolescents with extreme obesity - Effects on weight loss in the first 9 months under real-life conditions

Schirmer Melanie , Brandt Stephanie , Knupfer Magdalena , Zorn Stefanie , Weihrauch-Blüher Susann , Wabitsch Martin

Introduction: The Glucagon-like Peptide(GLP1)-analogue liraglutide is the first drug approved for the treatment of obesity in adolescents in Europe. While clinically relevant effects of liraglutide treatment in adolescents with obesity had been shown in a phase III study, there are no reports about the use under real-life conditions in these patients. Our aim was to report the effect of treatment with liraglutide on body weight loss in a cohort of adolescents ...

Glucocorticoid-mediated leptin secretion from human adipocytes is dependent on glucose availability

Tews Daniel , Brandt Stephanie , von Schnurbein Julia , Fischer-Posovszky Pamela , Wabitsch Martin

Background: Leptin is produced by adipocytes and regulates central hunger and satiety sensation. While the central leptin effects are well understood, little is known about the regulation of peripheral leptin production. Clinical data demonstrate that leptin levels are rapidly declining upon fasting, suggesting that leptin secretion is acutely regulated by nutrient availability. Although it has been previously shown that leptin secretion is under control by gl...

Comparison of long-term height outcomes in pediatric patients with growth hormone deficiency receiving once weekly somatrogon with those of matched patients treated with once-daily somatropin in the Kabi/Pfizer International Growth Study (KIGS)

Paliwal Yuvika , Carlsson Martin , Zhang Richard , Lee Peter , Korth-Bradley Joan , Taylor Carrie , Cara Jose

Objectives: Somatrogon is a long-acting recombinant human growth hormone (GH) approved in the EU and other countries for once-weekly treatment of pediatric patients with GH deficiency (GHD). In this analysis, height outcomes of somatrogon-treated patients in a phase 3 trial (CP-4-006) were compared with historical data from matched somatropin-treated patients enrolled in KIGS.Methods: In trial CP-4-006, patients were ran...

Changes in body composition in transgender adolescents during puberty suppression and hormone treatment

Boogers Lidewij , Reijtenbagh Sterre , Wiepjes Chantal , van Trotsenburg Paul , den Heijer Martin , Hannema Sabine

Context: Transgender adolescents can be treated with puberty suppression (PS) using GnRH agonists (GnRHa), and subsequent hormone therapy (HT). Up to this date, it has not been described at what rate body composition in transgender adolescents changes during the first years of treatment. Also, it is unknown whether Tanner stage at which treatment is initiated, might affect this treatment outcome.Methods: Transgender adol...
