Diabetes mellitus is a chronic disease. The risk of microvascular complications is correlated with hemoglobin A1c (HbA1c) level [1] Educating the diabetic patient to keep an HbA1c below 7% reduce the risk of long-term complications. We report the case of a 15 years old teenager, with chronical headache, referred for diabetes mellitus with a fasting glycemia of 83 mg/dl (normal < 100) and an HbA1C of 8.3% using an Ion-exchange High Performance Liquid Chromatography (HPLC, Ad...

Background: CHARGE syndrome is a variable entity. Clinical diagnosis is based on the Blake-Verloes criteria and can be confirmed by identifying a mutation in CHD7. Hypoplasia of the genitalia is a common feature and is most often attributable to hypogonadotropic hypogonadism which is described in 81% of the males and 93% of the female patients. Other genital anomalies are rare. Combined agenesis of the uterus and ovaries is so far only reported in one patient with sus...

Aims: In children with new-onset type 1 diabetes mellitus (T1D), insulin dose regimens vary substantially. According to current ISPAD recommendations, the initial total daily dose (TDD) should range from 0.7 to 1.0 IU/kg BW/day. Adjusting TDD to achieve normal blood glucose concentration can take several days. The primary objectives of our INSENODIAB (INsulin SEnsitivity in New Onset type 1 DIABetes) study were to assess how patient characteristics influence i...

Background: Children with biallelic GHRHR gene pathogenic variants share a phenotype of growth failure starting in infancy and resulting in a proportionate short stature and bone age delay due to a complete isolated growth hormone (GH) deficiency. The genotype ranges from rare promotor mutations to the more frequent splicing mutations, some genotypes being specific to certain geographic areas. Diagnosis is mainly made around the age of 7 years and more often i...

Background: TransCon hGH is a sustained-release prodrug in development as a long-acting GH for children with growth hormone deficiency (GHD). TransCon hGH consists of a parent drug, growth hormone (hGH; somatropin), that is transiently bound to a carrier via a TransCon linker. The carrier extends hGH circulation time in the body and fully active hGH is released over one week at physiologic pH and temperature. Unlike other molecules in development, TransCon hGH...

Lonapegsomatropin (TransCon hGH) is an investigational once-weekly prodrug of somatropin for the treatment of GHD. Previous trials in treatment-naïve (52-week heiGHt Trial) and treatment-experienced children (26-week fliGHt Trial) have reported the efficacy and safety of lonapegsomatropin. Subjects were eligible to enter the open-label extension enliGHten Trial, which continues to evaluate weekly lonapegsomatropin in pediatric GHD. In heiGHt, treatment-naïve subjects...

Introduction: Differential diagnosis of partial central diabetes insipidus (PCDI) and primary polydipsia (PP) can be challenging. Copeptin is the C-terminal segment of the vasopressin precursor peptide that represents a novel and stable biomarker. Arginine infusion produces a nonosmotic stimulus that causes an increase in copeptin concentrations in healthy subjects. Arginine-stimulated copeptin concentrations have been used to differentiate between patients wi...

Background: The potential benefit of growth hormone (GH) therapy on health-related QOL (HQoL) of children with short stature related to GH deficiency (GHD) or smallness for gestational age (SGA) has not been well documented.Objective and hypotheses: Our objective was to assess potential disease and treatment related predictors for a poor HQoL in GH treated children. Children with male gender, SGA disorder, greater height deficit at start of GH and poor h...

Background: Bilateral testicular regression (BTR) is characterized by the absence of both testicles in a newborn male or shortly thereafter, and presenting as bilateral cryptorchidism with undetectable AMH levels and the absence of Müllerian structures on pelvic ultrasound. Depending on when the regression occurs during fetal development, the condition can be associated with a micropenis. Few studies have explored the etiology and long-term outcome of BTR...

Background/ Aim: Over the past 6 years, the IGF1/ IGFBP3 generation test (IGFGT) has been used in Belgium in a standardized form to identify children with severe primary IGF1 deficiency (SPIGFD). In this study, the discordance of the IGF1 and IGFBP3 responses during an IGFGT and the prevalence of SPIGFD were analyzed in a cohort of children with short stature (height SDS < - 2) and presenting with low (below lower reference limit) serum IGF1 level and norma...
