Objective: To provide etiology-based diagnostics to pediatric patients with diabetes in Belgium using routine clinical phenotyping and thorough genotyping.Methods: A Belgian GENEPEDIAB study consortium was created to screen, using routine diagnostic tools, for monogenic forms of diabetes in pediatric patients followed in convention centers for type 1 or type 2 diabetes, while presenting atypical biological and clinical f...

Context: We previously observed that continuous subcutaneous infusion (CSI) of gonadotropins in infants with congenital hypogonadotropic hypogonadism (CHH) can mimic the hormonal pattern of minipuberty.Objective: Describe the peripubertal outcome in gonadotropins CSI treated patients.Patients: A retrospective study was realised in Bicetre Hospital between 2004 and 2022. Follow-up d...

Objectives: Despite high prevalence rates of childhood obesity, youth-onset T2DM occurs in a comparably lower incidence in Europe than in other world regions. Available data from cohorts of obese children and adolescents living in the US suggest a parallel decline of insulin sensitivity and β-cell function as key factors in the pathophysiology of early-onset T2DM. If these results can be applied to European children and adolescents is currently unknown.</...

Presently, the autoimmune character of T1D is challenged, but it is indisputable that inflammation plays a key role in its development. We hypothesized that glucotoxicity could contribute to β-cell mass destruction through maintenance of inflammation. Here, we aimed to evaluate, after diabetes onset, the potential of empagliflozin (EMPA) to protect β-cell mass against glucotoxicity, in monotherapy or in association with GABA, tested for its potential to increas...

Introduction: Hormonal deficits are well known complications after allogeneic human stem cell transplantation (alloHSCT) in childhood and treated according to existing guidelines. It is assumed that bone mass and strength accrual during puberty is also often impaired, due to toxic therapy and prolonged inactivity, but data on bone geometry and strength are scare in this particular group.Objective/Patients and Methods: Cr...

Introduction: X-linked hypophosphatemic rickets (XLHR) is due to mutations in the PHEX gene inducing increased levels of fibroblast growth factor 23 (FGF23), phosphate wasting, hence rickets. FGF23 is suspected to be as an important metabolic regulator of glucose and lipid metabolism.Objective: To describe the metabolic profile (body mass index, blood pressure, glucid and lipid profile) in patients with XLHR and evaluate the correlation between FGF23 lev...

Background: X-linked hypophosphatemic rickets (XLH) represents the most common form of hypophosphatemia and leads to vitamin D resistant rickets in children. Even though cranial vault and craniovertebral anomalies of potential neurosurgical interest, namely early closure of the cranial sutures and Chiari type I malformation- have been observed in XLH patients their actual incidence is not established.Aim: Describe and analyze the incidence of cranial and...

Background: New-Onset Diabetes after Transplant (NODAT) is a well characterized entity in adult population but less described in paediatric and adolescent population. The development of NODAT is associated with reduced graft function. The consensus for its management is largely available for adult population with a lack of specific guidelines applicable to the paediatric population.Case: A 16-year-old patient with an established renal failure and visual ...

Introduction: Graves’s disease is frequent in women, its prevalence being 0.5–2% and its incidence 0.1–1% during pregnancy. Both TSH anti-receptor antibodies and the synthetic antithyroid drugs cross the placenta, increasing the risk of hypo- and/or hyperhtyroidism. Our objective is to describe the thyroid status of fetus and newborns from women with Graves’s disease referred to our Department.Materials and methods: We included childr...

Background: Silver-Russell syndrome (SRS) is a clinically and genetically heterogeneous disorder, which remains a clinical diagnosis. The Netchine-Harbison clinical scoring system (NH-CSS), recently adopted by the first international consensus on SRS, defines SRS with at least 4 of the 6 following criteria: born SGA, postnatal growth retardation, relative macrocephaly at birth, prominent forehead, body asymmetry and early feeding difficulties. It is related to 11p15 ICR1 loss ...
