Background/Aims: Cryptorchidism or undescended testis is a prevalent congenital urogenital condition affecting male newborns with an incidence rate ranging from 1.0 to 4.6%. Mouse models have implicated INSL3 and its receptor RXFP2 (formerly known as GREAT or LGR8) in the development of the condition. RXFP2 acts as a G protein-coupled receptor that triggers the generation of cAMP by binding INSL3. But despite the established role in testicular descent, so far ...

Alterations in resting-state functional connectivity in patients with congenital adrenal hyperplasia

Messina Valeria , van´t Westeinde Annelies , Padilla Nelly , Lajic Svetlana ,

Background: Patients with congenital adrenal hyperplasia (CAH) are treated with life-long glucocorticoid (GC) replacement therapy. Negative effects on cognition, brain structure and function during working memory tasks have been identified. To date, no studies on functional connectivity during rest have been performed in patients with CAH. One study conducted on patients with Cushing’s syndrome, another disorder of cortisol imbalance, suggests that long-t...

Serial 3-Dimensional Ultrasonographic Evaluation of Foetal Adrenal Volumes in the 2nd and 3rd Trimester of Pregnancy Characterises Human Adrenal Development in utero

Baftic Nerma , Katugampola Harshini , Meso Muriel , Allen Rebecca , Marleen Shemoon , Elahi Shezan , Aquilina Joe , Dunkel Leo , Storr Helen

Background: The human foetal adrenal (FA) undergoes vast physiological changes as pregnancy progresses. Original descriptions of FA development emerged following morphometric studies from spontaneous/medical terminations. These revealed the greatest increase in FA size was during the first trimester. Recently, sonographic evaluation of human FA volume and length has led to the creation of normal FA growth centiles and correlations between FA size and estimated foetal weight (E...

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...

Background: The melanocortin-4 receptor (MC4R) pathway is a key regulator of energy balance and satiety. Variants in genes upstream of MC4R encoding leptin receptor (LEPR), proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1(PCSK1) and those involved in Bardet-Biedl syndrome (BBS) can impair MC4R pathway signaling. Clinically, these variants are characterized by hyperphagia (Pathologic insatiable hunger) and early-onset, severe obesity. E...

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...
