Background: In gender dysphoric (GD) adolescents with advanced pubertal development, psychological relief can be attained with progestins, which are much cheaper and easier to administer than GnRHa. Moreover, use of GnRHa has been shown to interfere with pubertal bone mass accrual. To date, few data exist on the effects of progestins on body composition (BC) and bone parameters in this population.Objective and hypotheses: To explore the effects of pro- a...

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: Premature pubarche is the appearance of pubic hair before 8 years in girls and 9 years in boys, being more frequent in girls. Current literature demonstrates associations between premature pubarche and metabolic and cardiovascular diseases.Objective and hypotheses: To evaluate the frequency of cardiovascular disease risk factors in girls with isolated premature pubarche (IPP).Method: Observational study using data from ...

Background: A national French registry was created to address the absence of data on final height and safety following long-term exposure to supraphysiological doses of growth hormone (GH) in children born small for gestational age (SGA).Methods: This observational, non-interventional study (NCT01578135) included GH-naïve and non-naïve SGA children treated with GH at 126 sites in France. The inclusion period wa...

Objective: Premature GH treatment discontinuation of SGA is usually linked to safety or ineffectiveness. However, this population is poorly addressed compared to those with final adult height (FAH). Authors investigated the journey of SGA prematurely discontinued Norditropin® treatment in a French real-life.Methods: Observational prospective ongoing study: 291 Norditropin®-treated SGA. Annual FU up to FAH. Descriptive anal...

Objective: Age and height at treatment start, target height, GH dose, and first year treatment response are among known criteria of GH deficiency (GHD) good responders (final adult height [FAH] >−2 standard deviation score [S.D.S.]) to GH treatment (GHT). The authors investigated whether the same criteria are applicable to SGA patients based on real-life ongoing French registry data.Methods: 291 SGA children treated with Norditro...

Objective: Bang et al. showed that Δ height and growth velocity (GV) the first year of treatment could be predictive factors of statural response in SGA (n=54). Poor responders showed GV <1SDS (55%) and Δ height <0.5SDS (45%). Moreover, Ortego et al. seems to confirm the suitability interest of KIGS mathematical model in a retrospective SGA cohort (n=103) showing that the percentage of good responders in the first year varies betwee...

Background: In spite of many studies demonstrating efficiency of recombinant growth hormone (rGH) on adult height in children born small for gestational age (SGA), great variability of response exists between treated patients. Predictive factors have been already studied such as age at start of treatment, rGH dose,…, but few data are available regarding the predictive values of pretherapeutic data on growth response.Objective and hypotheses: The ma...

Background: Turner syndrome, characterized by complete or partial absence of second sexual chromosome, is responsible for phenotype of variable severity.Objective and hypotheses: The main objective of this work is to describe the evolution of the age at diagnosis of Turner syndrome over time. We also performed a phenotypic and genotypic description and we assessed evolution over time.Method: It is a monocentric descriptive observat...

Background: Turner syndrome (TS), affects approximately 1/2500 live female births. The clinical features range from a severe phenotypic character to reduction of final height and premature ovarian failure.Objective and hypotheses: Processing of sensory information from visual, vestibular and somatokinesthetic systems is required to organize an adequate motor response aiming at gaze and posture stabilization according to the expected task and to the envir...
