Background: Biallelic mutations of the CYP11B2 aldosterone synthase gene cause deficiency of aldosterone synthesis. Patients exhibit isolated deficiency of aldosterone biosynthesis, increased plasma renin activity, increased steroid precursors desoxycorticosterone, corticosterone, as well as 18-hydroxy-desoxycorticosterone, and show salt wasting and poor growth. The aldosterone synthase enzyme has 18-hydroxylase (corticosterone methyloxidase type I, CMO I) and 18-oxidase (CMO ...

Background: Serum dihydrotestosterone (DHT) is an important analyte for the clinical assessment of disorders of sex development. It is also reportedly a difficult analyte to measure. Currently there are significant gaps in the standardisation of this analyte, including no external quality assurance (EQA) program available worldwide to allow for peer performance review of DHT.Objective and hypotheses: We therefore proposed to establish an EQA program for ...

Background: Male preterm infants are at increased risk of neonatal mortality when compared to their female counterparts. The mechanisms explaining this male disadvantage are not fully elucidated yet.Objective and hypotheses: To compare glucocorticoid metabolite excretion in urine obtained at day 10 between male and female infants born with a very low birth weight (VLBW; i.e. <1500 g). We hypothesized that male preterm infants have impaired adrenocort...

Background: Congenital hypothyroidism, one of the most important preventable causes of mental retardation, is a clinical condition characterized by thyroid hormone deficiency in newborns.Objective and hypotheses: Congenital hypothyroidism is most often caused by defects in thyroid development leading to thyroid dysgenesis. TSH receptor (TSHR) is the main known gene causing thyroid dysgenesis in consanguineous families with congenital hypothyroidism. In t...

Objective: Although low birthweight (bw) and unfavourable intrauterine conditions have been associated with metabolic sequelae in later life, little is known about their impact on glucocorticoid metabolism. We studied monozygotic twins with intra-twin bw-differences from birth to adolescence to analyse the long-term impact of bw and catch-up growth on glucocorticoid metabolism.Methods: 46 monozygotic prepubertal twin-pai...

Introduction: Thyroid abnormalities such as subclinical or overt hypothyroidism are common in children with Down syndrome (DS) with ranges from 4% to 19.5%, whereas Graves´ disease (GD) is extremely rare (ranges 0.6%-0.9 %).Aims: To evaluate clinical features, course, and treatment of GD in children with DS.Patients and Methods: Among 161 children with GD, diagnosed between 1...

Background and aim: Medulloblastoma is a highly malignant childhood brain tumor, requiring treatment with high dose cranio-spinal irradiation and aggressive chemotherapy. Survivors of are at high risk for multiple endocrine deficiencies, including growth retardation and growth hormone (GH) deficiency. Previous studies reported decreased final adult height in survivors of childhood medulloblastoma, with height standard deviation score (SDS) ranging from -1.9 to...

Introduction: Type 1 diabetes has a major impact on not only the person diagnosed, but also their families/carers. Diabetes control is affected by many factors. Our diabetes patient cohort has a very high level of social burden which we feel impacts significantly on the management of their diabetes.Methods: We performed a retrospective analysis of all young people supported by the Evelina London Children’s Hospital diabetes team in 2017 looking at a...

Background: Classically adrenal insufficiency presents with hyponatraemia and hyperkalaemia, however the differential may be of alternative origin. Atopic dermatitis is a common inflammatory skin disease of infancy and childhood. In severe cases, the exudation from wet lesions can produce serious complications such as infection+very rarely electrolytes abnormalities as seen in this case.Case report: A 6-month-old female infant was referred for endocrine ...

Background: Neonatal diabetes mellitus (NDM) presents within 6months of life, is either permanent (PDM) or transient (TND). The incidence is 400 000/live births. Monogenic accounts for the majority of cases. We describe the case of what appears to be a familiar NDM with no current known cause.Case report: EM presented at 3 weeks old. She was born at term, IUGR (2.3 kg) with one day history of diarrhoea, vomiting and anorexia. There was no history of poly...
