Genetic Variation of AMH Signaling Affects AMH and Inhibin B Levels in Healthy Peripubertal Girls

Hagen Casper P , Almstrup Kristian , Main Katharina M , Juul Anders

Background: Anti-Müllerian hormone (AMH) is produced by small growing ovarian follicles. It inhibits both FSH induced maturation of follicles as well as aromatase activity. Genetic variation of AMH signalling is associated with age at menopause and circulating oestradiol levels, i.e. AMH rs10407022 T>G (intragenic) and AMHR2 rs11170547 C>T (putative enhancer).Objective and hypotheses: This present study aims to investigate ...

A Missense Mutation in MKRN3 in a Danish Girl with Central Precocious Puberty and Her Brother with Early Puberty

Kansakoski Johanna , Raivio Taneli , Juul Anders , Tommiska Johanna

Background: Idiopathic central precocious puberty (ICPP) results from the premature reactivation of the hypothalamic-pituitary-gonadal axis leading to development of secondary sexual characteristics prior to 8 years in girls or 9 years in boys. Mutations in the maternally imprinted MKNR3 gene are the most common identified genetic cause of ICPP to date. Expression of MKRN3 in the arcuate nucleus is presumed to be inhibitory to GnRH secretion, but the exact mechanism remains un...

Variation of Environmental Chemicals Measured in Serum During Pregnancy

Assens Maria , Frederiksen Hanne , Juul Anders , Main Katharina

Background: Significant changes in metabolism and water equilibrium are registered during pregnancy. However, very limited previous investigations have been carried out on variations of exposure levels and metabolism of non-persistent environmental chemicals during pregnancy.Objective and hypotheses: The objective of this longitudinal study is to describe variation in exposure of pregnant women to environmental chemicals. We hypothesise that variation in...

Are Short Children with Low GH Secretion Metabolically Different from Children of Normal Height?

Tidblad Anders , Ekstrom Klas , Ritzen Martin , Marcus Claude

Background: Severe GH deficiency (GHD) leads to several metabolic effects in the body ranging from abnormal body composition to biochemical disturbances such as high insulin sensitivity. However, less is known regarding these parameters in children with a milder deficiency in GH secretion.Objective and hypotheses: To analyse if short children with a relatively low GH secretion differ metabolically from healthy children of normal height.<p class="abst...

Sleeptime-excreted total urinary luteinizing hormone concentrations reveal that the onset of central puberty occurs at around the same time in boys and girls: a longitudinal study

Demir And , Hero Matti , Juul Anders , M. Main Katharina

Objectives: We designed a longitudinal study to investigate the association between central pubertal activation with age at the appearance of clinical signs of puberty. We, therefore, assessed nocturnal gonadotropin secretion which can be detected in the form of total luteinizing hormone (LH) immunoreactivity in the daytime- and sleeptime-excreted urine.Methods: Thirty healthy volunteers (17 boys and 13 girls, aged 3.4&n...

Introduction: The ESPE e-Learning web portal is a free, globally accessible online tool to enhance learning in Paediatric Endocrinology and Diabetes. Since August 2022, the e-learning content includes 30 accredited hours of ESPE/ISPAD e-learning Continuing Medical Education (CME) courses with ten core modules each in Paediatric Endocrinology, Paediatric Endocrinology in Resource Limited Setting (RLS) and Paediatric Diabetes. The CME modules were created by wor...

Abdominal fat Distribution Measured by Magnetic Resonance Imaging in 197 Children Aged 10–15 Years – Correlation to Anthropometry and Dual X-Ray Absorptiometry

Tinggaard Jeanette , Hagen Casper P , Mouritsen Annette , Mieritz Mikkel G , Wohlfahrt-Veje Christine , Fallentin Eva , Larsen Rasmus , Christensen Anders N , Jensen Rikke B , Juul Anders , Main Katharina

Background: Obesity in childhood is defined by age- and sex-specific BMI cut-off values. However, BMI does not disclose the distribution of fat mass. Increased abdominal adipose tissue is associated with a higher risk of cardio-metabolic disease in adulthood. Thus, precise measurements of abdominal adipose tissue in children may enable early prevention of disease.Objective and hypotheses: To validate measurements of abdominal adipose tissue by anthropome...

Prediction of Germ Cell Cancer Occurrence in Postpubertal Individuals with Androgen Insensitivity Based on Pathological Findings and Cancer Predisposition SNPs

Background: Gonadectomy is generally postponed until early adulthood in complete androgen insensitivity syndrome (CAIS) and close surveillance of gonads in situ proposed in males with partial AIS (PAIS). Delaying gonadectomy further is controversial given the lack of data regarding germ cell cancer (GCC) development in adulthood and the absence of biomarkers for noninvasive GCC screening.Aims and objectives: To study the prevalence of invasive G...

Deep subcutaneous adipose tissue is associated with hyperinsulinemia in adolescents

Cerenius Sara Y. , Stenlid Rasmus , Aydin Banu , Weghuber Daniel , Bergsten Peter , Forslund Anders

Introduction: Abdominal subcutaneous adipose tissue (SAT) is subdivided into two depots by the fascia of Scarpa. The deep SAT (dSAT) and superficial SAT (sSAT) are morphologically and metabolically distinct, with dSAT reportedly being more similar to visceral adipose tissue (VAT) in terms of elevating the risk for obesity-related complications. Conversely, sSAT appears to be more similar to lower-body SAT. The relationship between dSAT and metabolic disease ha...

Bone mass and biomarkers in young women 3 years after intensive nutrition therapy for severe anorexia nervosa

Svedlund Anna , Pettersson Cecilia , Tubic Bojan , Ellegård Lars , Elfvin Anders , Magnusson Per

Purpose: Anorexia nervosa (AN) increases the risk of impaired bone health, low areal bone mineral density (aBMD), and subsequent fractures. This study investigated the long-term effects on bone and biomarkers in young women with AN.Methods: Twenty-five Swedish female AN patients, median age 21.0 years (16.1 to 24.3 years), median BMI 15.4 kg/m2, were included, 22 patients completed a high-energy in-patient treatment for ...
