Background: Down Syndrome (DS) patients have a higher incidence of primary hypothyroidism. We previously demonstrated that transgenic mice overexpressing Dyrk1A had developmental (larger primary thyroids at E15.5 stage of development), morphological (disorganized follicles) and functional (significant lower plasma T4) impairments similar to DS thyroidal impairments (Endocrinology 2015). DYRK1A, localized in the DS critical region on chromosome 21, is therefore the can...

Background: The post-authorization registry, EU-IGFD, was initiated in Dec-2008 to collect data in children with growth failure receiving Increlex® (Mecasermin [rDNA Origin] Injection).Objective and hypotheses: To report patient characteristics, safety and effectiveness data in poor-responders (i.e. with change in year 1 Height SDS <0.3).Method: European, multicentre, open-label, observational study; eCRF data collection.<...

Background: The post-authorization registry, European Increlex® (Mecasermin (rDNA Origin) injection) growth forum database (EU-IGFD) was initiated in Dec 2008 to collect data on children with growth failure treated with Increlex®.Objective: To report 4-year safety and effectiveness data.Methods: Multicenter, open-label observational study, eCRF data collection.Results: As of 30...

Background: The post-authorisation registry, European Increlex® Growth Forum Database (EU-IGFD), initiated in December 2008, collects data in children receiving Increlex (mecasermin (rDNA origin) injection) for growth failure, including Laron syndrome (LS) (severe primary IGF1 deficiency with confirmed GH-receptor mutation).Objective and hypotheses: Report safety and effectiveness data in children with LS.Method: Multicentre, ...

Background: The post-authorisation registry, European Increlex® (mecasermin (rDNA origin) injection) Growth European Increlex Growth Forum Database (EU-IGFD), initiated in December 2008, collects safety and efficacy data in children receiving Increlex® for growth failure. Hypoglycaemia has been reported as a common adverse event (AE) during any IGF1 replacement therapy in randomised clinical trials, and is therefore of interest in real-life sett...

Background: Renal transplantation (RTx) is the most common solid organ transplant procedure. Several studies have reported on puberty and gonadal function in female RTx recipients with controversial results.Objective: We sought to describe puberty and gonadal function in adolescents after RTx before 16 years.Methods: We reported retrospectively the clinical signs of puberty, growth, medication and graft function of 20 girls aged 19...

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...

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 ...

Somapacitan (Novo Nordisk A/S) is a long-acting GH derivative, approved for once-weekly administration in children and adults with GHD. IGF-I is monitored and includes a fraction bound to binding proteins, e.g., IGF binding protein-3 (IGFBP-3). The IGF-I/IGFBP-3 molar ratio can be used as surrogate marker for freely circulating bioactive IGF-I. REAL4 is a randomised, open-label, multi-national phase 3 trial (NCT03811535) with a 52-week main phase and a 3-year extension (week 5...

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...
