Persistence to growth hormone treatment and clinical characteristics of paediatric patients with growth hormone deficiency: A retrospective database study

Mori Jun , Sato Yukihito , Dateki Sumito

Background: For many years, raising awareness on early referral to endocrinologist, early diagnosis, and treatment continuation for paediatric patients with growth hormone deficiency (GHD) has been continued in Japan. However, the current status of trends in age at diagnosis and of treatment continuation have not been fully clarified.Aim: The aim of this study is to estimate the persistence to growth hormone treatment (G...

A case of NARS1 deficiency resulting in diabetes mellitus with liver cirrhosis and pancreatic atrophy

Higuchi Shinji , Kitayama Kana , Yorifuji Tohru , Mori Jun

Background: Aminoacyl tRNA synthetases (ARSs) are enzymes that bind amino acids to tRNAs, and many of their genetic variants are known to be pathogenic. Asparaginyl Aminoacyl tRNA synthetase (NARS1) deficiency was first reported as a cause of microcephaly in 2020. NARS1 deficiency is characterized by microcephaly, psychomotor retardation, epilepsy, congenital abnormalities of the limbs and skeleton, and a peculiar facial appearance. However, there have been no...

Erythropoietin Activates Classical Brown Adipose Tissue Through the Erythropoietin Receptor/STAT3 Pathway, Improving Obesity and Glucose Homeostasis in High Fat Diet-induced Obese Mice

Background, aims and objectives: We hypothesized that classical brown adipose tissue (cBAT) could play a crucial role in the anti-obesity effects of erythropoietin (EPO). Our study highlights the mechanism in which EPO treatments could upregulate energy expenditure and improve glucose homeostasis through cBAT in obese mice fed with a high-fat diet (HFD).Method: C57BL/6J mice had been fed with HFD since the age of 4 weeks (HFD mice). We administered recom...

Effective GH Replacement with Once-weekly Somapacitan in Japanese Children with GH Deficiency: 2-year Results from REAL4

Ohata Yasuhisa , Mori Jun , Fujisawa Yasuko , Sato Yukihito , Röhrich Sebastian , Højby Rasmussen Michael , Beck Bang Rikke , Horikawa Reiko

Growth hormone deficiency (GHD) in children results in reduced adult height. Children with GHD typically require daily subcutaneous (s.c.) injections of growth hormone (GH). Daily injections are burdensome for both patients and their caregivers and reduced adherence negatively impacts clinical outcomes. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, aiming to ov...

Once-Weekly Somapacitan vs Daily GH in Children with GH Deficiency: The Randomized Phase 3 REAL 4 Trial

Background: Growth hormone (GH) replacement therapy usually requires daily subcutaneous (s.c.) injections that can be burdensome for patients and their caregivers. Long-acting GH formulations aim to establish a less burdensome dosing regimen that is as safe and efficacious as daily GH to potentially improve adherence and clinical outcomes. Somapacitan, a long-acting reversible albumin-binding GH derivative, is in development for once-weekly s.c. administration...

The Collapse of the BDNF/POMC System in the Hypothalamus is Responsible for the Extreme Obesity with Hyperphagia Observed in Female Heterozygous MeCP2 Null Mice

Objective and hypotheses: The aim was to elucidate the mechanism underlying the extreme obesity observed in female heterozygous MeCP2 null mice fed a high-fat diet.Method: We examined the molecular biology and physiology of female heterozygous MeCP2 null mice (Mecp2tm1.1Bird/J, MeCP2+/− mice) fed a high-fat diet (HFD) for 12 weeks since 4 weeks of age using analytical tools. C57/BL6 mice were used as controls.<p class="abs...

GH replacement therapy with once-weekly somapacitan in children with GH deficiency is effective and well-tolerated: 2-year results from REAL4

Miller Bradley , Blair Joanne , Højby Rasmussen Michael , Maniatis Aristides , Mori Jun , Böttcher Volker , Bang Rikke , Polak Michel , Horikawa Reiko

Daily subcutaneous (s.c.) injections of growth hormone (GH) to treat GH deficiency (GHD) in children is burdensome for both patients and caregivers. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, and aims to overcome the treatment burden of daily injections. REAL4 is a multi-national, randomised, open labelled phase 3 trial with a 52-week main phase followed by ...

Predicting Average IGF-I Concentration for Once-Weekly Somapacitan in Children with Growth Hormone Deficiency

F. Backeljauw Philippe , Kamal Lyauk Yassine , C. Blair Joanne , S. Miller Bradley , Mori Jun , Højby Rasmussen Michael , Juul Kildemoes Rasmus

Growth hormone (GH) stimulates insulin like growth factor I (IGF I) release. IGF-I is the standard biomarker for monitoring GH effects during treatment and to achieve optimal long-term safety, and to a limited extent, monitor efficacy in children with GH deficiency (GHD). The IGF I profile during treatment with a long acting GH (LAGH), such as once weekly somapacitan (Novo Nordisk), differs from the daily GH profile by exhibiting larger peaks and troughs over the dosing interv...
