Introduction: Growth promoting effects of GH occur in parallel with its impact on insulin sensitivity and lipid metabolism; underlying biological networks that link these actions are not defined. Our objective was to identify gene expression (GE) networks linking growth with metabolic responses in GH-treated children with GHD.Methods/design: Pre-pubertal children with GH Deficiency GHD (n=125) were enrolled from the PREDICT short-term (NCT002561...

Introduction: There are few published large-cohort studies examining the long-term impact of GNRH analogue treatment for precocious puberty (PP) on fertility in women. The PREFER study analysed fertility in a large cohort of women treated during childhood for PP with triptorelin.Methods: PREFER was a longitudinal, descriptive, non-comparative, epidemiological study conducted in 23 centres in France between February 2007 and November 2009. Women aged &#88...

Background: A basal 17-hydroxyprogesterone (17-OHP) plasma level of 6.0 nmol/l was suggested as a threshold for the diagnosis of non-classical congenital adrenal hyperplasia (NCCAH), particularly in children presenting with precocious pubarche (PP).Objective: The present study aimed to determine if this threshold could lead to underdiagnosis of NCCAH.Method: In a retrospective study the cohort of pediatric patients (n=145,...

Background: McCune–Albright syndrome (MAS) is a sporadic and rare disorder, clinically defined by the classic triad of cafè-au-lait skin lesions, polyostotic fibrous dysplasia, and peripheral precocious puberty. Precocious puberty is common in girls, but has been reported in only 15% of affected boys. Clinical trials on therapeutic management of precocious puberty in MAS boys are limited to case reports or small patient cohorts and no data are reported about final he...

Introduction: Gsα is imprinted in human thyroid glands and this appears to be important in the development of moderate TSH resistance in pseudohypoparathyroidism (PHP) 1A and less severe TSH resistance in some, but not all, other forms of PHP. Obesity is a clinical condition in which subclinical alterations of thyroid function have been reported, although the relationship between thyroid status and obesity remains unclear. It is uncertain if this biochemical abnormality m...

Background: DMXL2 haploinsufficiency in humans was recently shown to cause the polyendocrine-polyneuropathia syndrome including a GnRH deficiency (OMIM #616113). The neuronal deletion of Dmxl2 in mice (Nes::Cre;Dmxl2loxp/wt) caused infertility and gonadotropic deficiency (Plos Biology 9 e1001952, 2014). Dmxl2 encodes rabconnectin-3α (rbcn-3α), which participates in the control of the V-ATPase activity an...

Background: In gender dysphoric adolescents GnRH agonists can be used to suppress pubertal development of the natal sex. Subsequently cross sex hormones can be given to induce pubertal development of the experienced gender. Only few data are available on the safety of this treatment. Lipid levels are known to increase during puberty and pubertal suppression may alter this increase. In gender dysphoric male-to female (MtF) adults oestrogens has been shown to result in a more fa...

Background: In gender dysphoric adolescents GnRH agonists can be used to suppress pubertal development of the natal sex. The metabolic implications of the pubertal suppression have not yet been explored. Insulin sensitivity is known to be influenced by pubertal changes. During puberty a decrease in insulin sensitivity is normally observed.Objective and hypotheses: The effects of GnRH agonists on insulin sensitivity during 2 years of treatment in adolesce...

Background: IGFI regulates early postnatal growth of preterm infants and also plays an important role in growth in childhood. Very-low-birth-weight (VLBW) infants are at risk for reduced growth in early childhood.Objective and hypotheses: To compare IGFI and the correlation to growth parameters in infancy and early childhood in VLBW and term appropriate for gestational age (AGA) infants.Method: We included 41 VLBW children and 64 t...

Background and Objectives: Childhood obesity is a global public health threat, with an alarming rise in incidence. Obesity at young age has short-term consequences, as well as long-term morbidity. It is, therefore, important to determine body composition longitudinal throughout infancy and childhood to prevent excess adiposity. Multiple methods are used to determine body composition in infants and young children, but none are described as suitable for longitud...
