Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...

Background: Nearly 10% of paediatric onset diabetes are auto-antibodies negative. Among them monogenic diabetes are frequently under-diagnosed. The major increase in the prevalence of childhood obesity is misleading with a risk of confusion between type 2 diabetes (T2D) and monogenic causes of diabetes.Objective and hypotheses: To report on two informative families with negative auto-antibodies childhood-onset diabetes cases.Method...

Background: The aim of this study was to examine plasma visfatin levels in pediatric patients with type 1 diabetes (T1D). Visfatin, a novel adipokine, is predominantly secreted by visceral adipose tissue and seems to have insulin-mimetic effects. It has not been studied in children and adolescents with type 1 diabetes (T1D) yet.Objectives: We studied 124 subjects; 62 patients with T1D: 31 girls, mean age 13.7±3.7 years; mean duration of diabetes 5.9...

Background: Congenital hypopituitarism is a rare disease. Although our understanding of the involved transcription factors is improving, mutations in candidate genes are rarely identified. Extra-pituitary symptoms can point towards new genes of interest. FOXL2 is mutated in blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), a rare affection that combines congenital alterations of eyelids with ovarian dysgenesis in some families. Moreover, we have previously reported ...

Introduction: The leptin-melanocortin pathway plays a key-role in weight control. Pathogenic variants in the five major genes (LEP, LEPR, POMC, PCSK1, MC4R) are associated with early severe obesity. However, the specific associated phenotype with presence of mono-allelic variants and especially BMI trajectories are not well known.Objective: In order to identify specific profiles, we compared BMI trajectories during the f...

Background: Onset of diabetes in the neonatal period with additional malformations e.g. congenital heart defects should always be suspicious for an underlying genetic disorder. For example, GATA6-mutations were identified in children with congenital heart defects and neonatal diabetes. The latter may be due to pancreas agenesis. Herein we present a novel GATA6-mutation in a boy with transient neonatal diabetes, diaphragmatic hernia, congenital heart defect and early onset scol...

Background: A one-month girl was referred to our unit for hypocalcemia. She was the first child of healthy non-consanguineous parents. Her family history was unremarkable except a miscarriage in the mother and oligoasthenospermia in the father that justified a medically assisted reproduction. She was born eutrophic at term after a pregnancy marked by a moderate gestational diabetes. On day 3, a routine neonatal screening revealed a severe asymptomatic hypocalcemia (total calci...

Background: Children and adolescents with chronic conditions are at increased risk of secondary osteoporosis. In adult patients, long-term anticoagulation (LTA) including Vitamin K antagonist (VKA) treatment is associated with lower bone mineral density and hip fractures. In children and adolsescent, risk factors for impaired skeletal health and the role of LTA on bone metabolism during the vulnerable phase of linear bone growth remain poorly defined.<p cl...

Background: Anti-Müllerian hormone (AMH) is produced by granulosa cells in small follicles prior to gonadotropin dependent growth and serum levels reflect the number of small antral follicles. There are currently no longitudinal data of individual AMH levels from infancy to adolescence.Aim: To evaluate whether AMH in infancy and childhood is associated with AMH levels and ovarian morphology peripubertal and in adole...

Congenital hyperinsulinism (HI) is the most common cause of persistent hypoglycemia in neonates, infants, and children, and is caused by genetic mutations in pancreatic beta-cells. Current therapies are burdensome, have limited efficacy, and are associated with significant morbidity. CRN04777 is a potent, orally-bioavailable, selective SST5 agonist that suppresses insulin secretion in the terminal steps of the insulin secretion pathway and could be useful for patients with con...
