Case presentation: A 3 years 10 months old British white girl presented with rapid weight gain of 11 kg over 4 months, hirsutism, central obesity, moon face, buffalo hump and hypertension.Investigations: Plasma cortisol, IGF-1 and ACTH levels were elevated. The 9am plasma cortisol was 1035 nmol/l (140–500) with simultaneous plasma ACTH 13 pmol/l (1–11). Plasma cortisol and ACTH levels responded to both dexamethasone suppression and CRH stimulat...

Objectives: Data on the role of gluten in type 1 diabetes (T1D) pathogenesis are scarce. We aimed to test whether gluten-free diet (GFD) can decelerate the decline in beta-cell capacity in newly diagnosed non-coeliac T1D children.Methods: Forty six children (aged 10.2±3.3 years) were recruited into this non-randomized self-selected intervention trial: 26 started with GFD, whereas 20 remained on standard diet. Main o...

Human growth is a complex trait. A considerable number of gene defects have been shown to cause short stature, but there are only few examples of genetic causes of non-syndromic tall stature. Besides rare variants with large effects and common risk alleles with small effect size, oligogenic effects may contribute to this phenotype. Exome sequencing was carried out in a tall male (height 3.5 SDS) and his parents. Filtered damaging variants with high CADD scores were validated b...

Introduction: Body temperature determinants include head-brain thermal homeostatic mechanisms and, in the human newborn (NWB), birth gestational age (GA). Estimated birth brain weight (BRW) ratio to birth body weight (BW)(BBR) resulted associated with GA and blood serum Insulin-like Growth Factor (IGF)-II(IG2) ratio to blood serum IGF Binding Protein-3 (IB3)(IG2 through chronologically-corresponding IB3, IG2/IB3R) in our previous NWB observations. Here we evaluate BRW, BW, BBR...

Aim: Recommendations for replacement glucocorticoids in CAH suggest a dose per body surface area (BSA) of glucocorticoids of 10-15mg/m2/day to maintain a 17-OH Progesterone (17OHP) level of 12-36 nmol/l across all ages. We used longitudinal analysis to assess whether biomarkers and dose of hydrocortisone varied with age in children within the I-CAH registry .Method: This retrospective multi-centre study, inclu...

Aim: Recommendations for the management of Congenital Adrenal Hyperplasia (CAH) outline a target 17-OH Progesterone (17OHP) of 12-36nmol/l, but do not specify target concentrations for Androstenedione (D4). We aimed to study the temporal variations of these biomarkers in patients from different geographical regions.Method: This retrospective multi-centre study, including 21 centres (14 countries), analysed serum biomarke...

Drosophila melanogaster as a study model has already significantly contributed to the understanding of the mechanisms of many human diseases. So far D. melanogaster has rarely been exploited as a model for human sex development. Nanda et.al already demonstrated in 2009 that the Drosophila orthologue of SOX9, Sox100B is essential for testis development in Drosophila. Similarly, we could demonstrate that the fly homolog of STARD8, cv-c</...

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...

Background: The ‘External Masculinization Score’ (EMS) is an objective method of scoring undervirilized genitalia in infants but may require further adaptation to capture the appearance of the genitalia more comprehensively across the phenotypic spectrum.Objective: To develop and validate a non-binary, standardized score that describes the range of appearance of external genitalia.Method: The external genitalia score (EGS...

Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...
