Genetic and Epigenetic Defects at the GNAS Locus Lead to Opposite Patterns of Fetal and Postnatal Growth

Grybek Virginie , Maupetit-Mehouas Stephanie , Hogler Wolfgang , Juppner Harald , Silve Caroline , Linglart Agnes

Background: Pseudohypoparathyroidism (PHP) is characterized by proximal tubular resistance to PTH and, in some disease variants, by Albright osteodystrophy. PHP is caused either by mutations in those regions of GNAS encoding Gsα (PHP1A and PseudoPHP) or by GNAS methylation defects (autosomal dominant (AD) and sporadic (spor) PHP1B). Phenotypic differences in fetal growth, post-natal growth and metabolism are observed in the different PHP types.<p cla...

Are Age and Initial BMI-SDS in Obese Children and Adolescents Associated with the BMI-SDS Courses During and after the Attendance of an Inpatient Weight-Loss Program (LOGIC-Trial)?

Brandt Stephanie , Wabitsch Martin , Heitkamp Melanie , Geilhof Barbara , Langhof Helmut , Halle Martin , Siegrist Monika

Background: It has been discussed in literature, that being severely obese and adolescent are predictive for failure in a behavior based weight-loss program.Objective: To investigate the association between age and initial BMI-SDS with BMI-SDS courses during and after the attendance of an inpatient weight-loss program.Design: The LOGIC-trial involves overweight and obese children and adolescents (6–19 years), who participate i...

Bilateral severe proliferative retinopathy, macular oedema, and lack of macrocytosis in an adolescent male with thiamine-responsive megaloblastic anaemia

Chandwani Manju , Spilioti Diamantina-Xanthi , How-Yaw Stephanie , Yong James , Mathapati Dannaya ,

Thiamine-Responsive Megaloblastic Anaemia (TRMA) is a rare autosomal recessive disorder emerging due to mutation in the thiamine transporter 1 gene. It presents with sensorineural hearing loss, non-immune diabetes mellitus and megaloblastic anaemia. Ocular manifestations of TRMA described so far include optic atrophy and cone-rod retinal dystrophy. This paper presents a case report of a British-Pakistani adolescent boy unexpectedly diagnosed with bilateral severe proliferative...

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...

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...

Achondroplasia: a novel deep intronic variant of the FGFR3 gene, c.1075 + 95C>G, disrupts mRNA splicing

Hogeabri Dorna , Schwarz Stephanie , Oehl-Jaschkowitz Barbara , Gawai Monika , Zemlin Michael , Rohrer Tilman

Background: In the vast majority of cases, achondroplasia and hypochondroplasia are attributable to hotspot missense mutations in the FGFR3 gene. 96% of patients have a G(1138)A and 3% have a G(1138)C point mutation. We report on a family whose members have a deep intronic mutation that leads to a novel cryptic splicing variant of the FGFR3 gene, and via this pathway results in new pathogenicity manifesting as achondroplasia.Case...

SPISE is more strongly correlated with cardiometabolic factors in adolescents with obesity than HOMA-IR, and is related to the amount of body weight reduction under lifestyle intervention

Tantari Giacomo , Brandt-Heunemann Stephanie , Maghnie Mohamad , Siegfried Wolfgang , Denzer Christian , Wabitsch Martin

Introduction: Impaired insulin sensitivity (IS) is a hallmark of increased cardiometabolic risk in adolescents with obesity. Surrogate markers of IS based on fasting insulin have important limitations. The Single-Point Insulin Sensitivity Estimator-Index (SPISE), obtained using the mathematical formula 600 × HDL-C^0.185/Triglycerides^0.2 × BMI^1.338, has been shown to be a predictor for detecting both insulin resistance and the risk of developing g...

A child with anti-thyroid arthritis syndrome

Introduction: Anti-thyroid arthritis syndrome (AAS) is a rare complication that may occur in patients treated with anti-thyroid drugs. Presentation is variable and may include myalgia, arthralgia, skin rash, high fever, and polyarthritis. Herein, we present a girl diagnosed with AAS. Case report: A 9-year-old girl was admitted to emergency complaining of fever and arthralgia. She was the second child of non-consanguineous healthy parents. She had been d...

An adolescent boy with PLS3 mutation causing severe thoracic kypho-scoliosis

Kilci Fatih , Jones Jeremy , Gürpınar Gözde , Koçyiğit Esra , Çakır Özgür , Ceylaner Serdar , Alanay Yasemin , Mine Çizmecioğlu-Jones Filiz

Introduction: Mutations of the PLS3 gene (MIM 300910), encoding plastin 3, are an extremely rare cause of osteogenesis imperfecta (OI). It has an X-linked inheritance and is characterized by early-onset osteoporosis and kyphosis, which can cause compression fractures, especially in the thoracic vertebrae. Although there are reports showing that bisphosphonates are effective in improving the bone mineral density of patients with PLS3 variants,...
