Pubertal Onset in Boys is Influenced by BMI and Genetic Variation of Fshb and Fshr: A Study in Two Population-Based Cohorts of Different Genetic Ancestry

Busch Alexander S. , Hagen Casper P. , Main Katharina M. , Almstrup Kristian , Pereira Anita , Corvalan Camila , Mericq Veronica , Juul Anders

Background: Age at onset of puberty exhibits a remarkable variation mirroring nutritional, environmental, socioeconomic and genetic factors. While large genome-wide association studies identified more than hundred genetic loci associated with age at menarche in girls, knowledge on loci associated with age at pubertal onset in boys is sparse. FSHB/FSHR genetic variants have been shown to affect pubertal timing in girls and reproductive parameters in men.<p class="a...

Long-Term Insulin Sensitivity and β-Cell Function in Short Children Born Small for Gestational Age Treated with GH and GnRHa: Results of a Randomised, Dose-response Trial

van der Steen Manouk , Lem Annemieke J , van der Kaay Danielle C M , Hokken-Koelega Anita C S

Background: Pubertal children born small for gestational age (SGA) with a poor adult height (AH) expectation can benefit from treatment with GH 1 mg/m2 per day (~0.033 mg/kg per day) in combination with 2 years of GnRH analogue (2 years GnRHa) and even more so with 2 mg/m2 per day (~0.067 mg/kg per day). Concerns haven been raised about the effects of GH and GnRHa on insulin sensitivity on the long-term.Objective and hypotheses: To ...

Computer-aided facial analysis as a tool to identify patients with Silver-Russell syndrome and Prader-Willi syndrome

Ciancia Silvia , Goedegebuure Wesley J. , Grootjen Lionne N. , Hokken-Koelega Anita C.S. , Kerkhof Gerthe F. , van der Kaay Danielle C. ,

Introduction: Genetic syndromes often show suggestive facial features that provide clues for the diagnosis. Considering the high number of genetic syndromes and the possible overlap of some features, memorizing facial gestalt is a challenging task for clinicians. DeepGestalt technology, and its app Face2Gene, has a growing impact on the diagnosis and management of genetic diseases by analyzing the features detected in one or more facial images of affected indi...

Long-term GH-treatment of children born small for gestational age (SGA) does not result in cerebrovascular abnormalities in adulthood compared to untreated controls

Dorrepaal Demi , Goedegebuure Wesley , Smagge Lucas , van der Steen Manouk , van der Lugt Aad , Hokken-Koelega Anita

Background: Increased cerebrovascular morbidity and mortality was reported in adults who were treated with growth hormone (GH) during childhood, including those born SGA, compared to the general population. However, previous studies did not have an appropriate control group of untreated SGA adults which was a major limitation.Objective: To assess cerebrovascular abnormalities (aneurysms, previous intracerebral hemorrhage...

Effects and safety of growth hormone (GH) treatment in 6 children with pycnodysostosis

Renes Judith , Sas Theo , Clement-de Boer Agnes , Zwaveling-Soonawala Nitash , van der Kaay Danielle , Hokken-Koelega Anita

Background: Pycnodysostosis is a very rare autosomal recessive skeletal dysplasia caused by cathepsin K deficiency. It is characterized by extreme short stature resulting in an adult height in males typically <150 cm and in females <134 cm. Bone-fragility and frequent fractures are present. There are few case-reports on the effects of GH treatment.Objective: To evaluate the effect and safety of GH in 6 patients wit...

Meta-analysis of DNA methylation datasets identifies aberrant DNA methylation of thyroid function and development genes in Down syndrome

Lauffer Peter , Zwaveling-Soonawala Nitash , Li Shaobo , Bacalini Maria , Naumova Oxana , Wiemels Joseph , Boelen Anita , Henneman Peter , de Smith Adam , van Trotsenburg Paul

Down syndrome (DS) is characterized by a higher incidence of congenital hypothyroidism (CH) and a high prevalence of subclinical hypothyroidism (SH) early in life. Children and adults with DS have an increased risk of developing autoimmune thyroid disease, however CH and early SH cannot be explained by thyroid autoimmunity. The etiology of CH and early SH in DS remains to be elucidated. Considering the recently discovered genome-wide transcriptional and epigenetic alterations ...

Body composition in children and adolescents with non-classic congenital adrenal hyperplasia and risk for metabolic syndrome components – an observational study

Ben Simon Asaf , Brener Avivit , Segev-Becker Anat , Yackobovitch-Gavan Michal , Uretzky Adi , Schachter Davidov Anita , Oren Asaf , Eyal Ori , Lebenthal Yael

Context: Non-classic congenital adrenal hyperplasia (NCCAH) diagnosed in childhood, whether treated or untreated, could pose an increased risk of obesity and metabolic derangements in adolescence and early adulthood. Both sustained hyperandrogenism and chronic glucocorticoid therapy may affect body composition. However, little is known about the body composition of subjects with NCCAH and its contribution to the development of adverse metabolic outcomes. <...

Growth Hormone Treatment in Adults with Prader-Willi Syndrome has Sustained Positive Effects on Body Composition

Damen Layla , Donze Stephany , Kuppens Renske , Bakker Nienke , de Graaff Laura , Alfen-van der Velden Janiëlle van , Stikkelbroeck Nike , Hokken-Koelega Anita

Context: In children with Prader-Willi syndrome (PWS), the benefits of growth hormone (GH) treatment are well established. Currently, when young adults with PWS have attained adult height (AH), they have to stop GH treatment. Several one year studies have shown that GH treatment is also beneficial for adults with PWS, improving body composition. However, little is known about the longer-term effects.Objective: To investi...

Normal IGF-Bioactivity and Low Free IGF-I in Patients with Prader-Willi Syndrome with High Total Serum IGF-I: Immunoreactive IGF-I Concentration Poorly Reflects IGF Bio-Activity and Bio-Availability.

Elizabeth Melitza , Donze Stephany , Pellikaan Karlijn , van den Berg Sjoerd , van Doorn Jaap , Peeters Robin P. , Hokken-Koelega Anita C.S. , de Graaff Laura C.G.

Introduction: Recombinant Growth Hormone (GH) has changed the lives of many patients with Prader-Willi Syndrome (PWS). GH treatment has beneficial effects on body composition, physical performance, cognition, psychomotor development, respiratory function and quality of life of patients with PWS. Due to the narrow therapeutic range, GH treatment is subject to strict limits. Clinicians measure serum immunoreactive Insulin-like Growth Factor 1 ('total IGF-I&#...
