Shapiro Lucy , Elahi Shezan , Baliey Joe , Perry Les , Martin Lee , Grossman Ashley , Akker Scott , Monson John , Drake William , Savage Martin , Storr Helen

Background: Cushing’s syndrome (CS) in children remains a challenge to diagnose and exclude. Published diagnostic guidelines for CS are heavily based upon adult data. The use of 24-h urinary free cortisol (UFC) measurements in the diagnosis of adult CS may have limited use. There is little data on the utility of 24-h UFC in children.Objective and hypotheses: We hypothesised that 24-h UFC is a robust and reliable screening test in children. The study...

Growth and Endocrinopathy in Wolfram Syndrome: The Experience of a Nationally Commissioned Specialist Clinic

Kershaw Melanie , Gleeson Susan , Williams Denise , Gupta Rajat , Ainsworth John , Kulkarni Archana , McCarthy Liam , MacPherson Lesley , Bates Rachel , McGee Marie , Barrett Timothy G

Background: Wolfram syndrome (WS) is a monogenic disorder associated with diabetes mellitus (DM), optic atrophy, diabetes insipidus (DI), neurological deterioration and deafness. Growth has been poorly characterised in case series.Objective and hypotheses: To determine growth and prevalence of endocrine disorders, qualify therapies and metabolic outcome for DM, and relationship of cranial MRI findings to clinical findings in children and young people (CY...

Maternal, rather than fetal, genetic variation in vitamin D metabolism is associated with umbilical cord blood 25-hydroxyvitamin D in pregnancies supplemented with cholecalciferol: findings from the MAVIDOS randomized controlled trial

Moon Rebecca , D’Angelo Stefania , Curtis Elizabeth , Cooke Laura , Davies Justin , Crozier Sarah , Godfrey Keith , Graham Nikki , Holloway John , Lewis Rohan , Cleal Jane , Inskip Hazel , Cooper Cyrus ,

Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

Investigation of primary adrenal insufficiency (PAI) in children with 46,XY differences in sex development (DSD)

Man Elim , Peters Catherine , Brain Caroline , Lichtarowicz-Krynska Ewa , Bahl Shailini , Buchanan Charles , Spoudeas Helen , Aitkenhead Helen , Hindmarsh Peter , Dattani Mehul , Achermann John ,

Background: When a baby presents with atypical genitalia, the most important diagnosis to consider is 21-hydroxylase deficiency (21OHD, CAH, 46,XX). However, primary adrenal insufficiency (PAI) can also occur in 46,XY children with differences in sex development (DSD), although this is less common. Known causes of 46,XY DSD-PAI include high blocks in steroidogenesis (STAR, CYP11A1); steroidogenic enzyme defects (HSD3B2, CYP17A1</...

A prospective study of children 0-8 years with congenital adrenal hyperplasia and adrenal insufficiency on treatment with hydrocortisone granules monitored by 17-OHP saliva sampling

Neumann Uta , Braune Katarina , Whitaker Martin J , Wiegand Susanna , Krude Heiko , Porter John , Digweed Dena , Voet Bernard , Ross Richard , Blankenstein Oliver ,

Context: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) require hydrocortisone replacement from birth. Continuous monitoring of therapy during growth is necessary. Until now, children were dependent on off label use with divided hydrocortisone tablets or pharmacy compounded capsules. A licensed paediatric formulation that allows accurate dosing down to 0.5mg is now available.Objective: ...

Analysis of Placental Steroidogenesis as a Cause of Recurrent Miscarriage

Suntharalingham Jenifer , Ishida Miho , Buonocore Federica , Valle Ignacio del , Solanky Nita , Demetriou Charalambos , Peskett Emma , Regan Lesley , Moore Gudrun , Achermann John ,

Background: Recurrent miscarriage (RM) is traditionally described as three or more consecutive pregnancy losses and remains a challenging condition, affecting 1-3% of couples trying to conceive. Although factors such as uterine abnormalities, maternal hypothyroidism and parental balanced translocations are associated with RM, in most situations the aetiology is unknown. The coexistence of RM and live births in many families suggests a potential association wit...

Duplication of Pituitary Gland-plus Syndrome presenting with a Transcranial Nasal Dermoid Cyst

Chandwani Manju , Spilioti Diamantina-Xanthi , Chumas Paul , Symth Alistair , Alvi Sabah , Nix Paul , Warren Daniel , Liddington Mark , Russell John , Elliott Mark ,

Duplicated pituitary gland in association with other midline craniofacial anomalies – also described as DPG-plus syndrome – is extremely rare. So far the only described endocrine associations are precocious or delayed puberty. We describe the multifaceted management of a female infant with DPG-plus syndrome. Interestingly, the patient also presented with trans-cranial nasal dermoid cyst and a nasal dimple with protruding hair, which has not been described in previous...

Introduction: Age at pubertal onset is a markedly inherited trait. The most common cause of pubertal delay, self-limited pubertal delay, is defined by the absence of secondary sexual characteristics after 13 years in girls and 14 years in boys, with progression before age 18. This study aimed to detect novel candidate genes for self-limited pubertal delay.Methods: Eighty-one patients with confirmed self-limited delayed p...

Growth, IGF-1 and IGFBP-3 Responses to Oral LUM-201 in OraGrowtH210 and OraGrowtH212 Trials in Pediatric Growth Hormone Deficiency (PGHD) over 12 to 24 Months on Treatment

Background: LUM-201, a potent long-acting oral GH secretagogue (GHS), acts on the GHS Receptor-1a to induce GH secretion. The best candidates for this investigative oral treatment are pre-pubertal children with moderate GHD (standard stimulation testing peak GH between ≥3 <10ng/ml) that respond positively to the LUM-201 Predictive Enrichment Marker (PEM) test (Bright et al JES, 2021). PEM positive responders have basal serum IGF-1 >30ng/ml and a peak ...

Background: Sequencing of Primary Ovarian Insufficiency (POI) cohorts have identified variants in >100 “POI genes” in up to 50% of women. Establishing pathogenicity of these variants is challenging. Whether early-onset POI (EO-POI; adolescent-onset) has a unique genetic profile remains unknown.Methods: We performed exome sequencing (Nonacus) in an EO-POI cohort (sporadic and familial) and unaffected family...
