Background: PHID syndrome has been recently described as a unique syndrome characterised by pigmented hypertrichosis; non immune mediated insulin depended diabetes mellitus (DM). Other associated features of the syndrome include pancreatic exocrine insufficiency, short stature and hypogonadism.Aims: To identify the genetic basis of PHID syndrome in six patients from five unrelated families and to characterise the endocrine features associated with this s...

Introduction: Congenital hyperinsulinism (CHI) is a disesase of severe hypoglycaemia, often due to in mutations in ABCC8/KCNJ11. Sirolimus, an mTOR inhibitor, has been reported to be successful in CHI patients, but the evidence is limited. We have aimed (i) to review the efficacy and safety profile of sirolimus, (ii) to assess the role of mTOR signalling pathways in CHI, (iii) to assess the impact of sirolimus in CHI pancreatic tissue.Methods: P...

Introduction: Asymptomatic hypercalcaemia in infants who are exclusively breast-fed is recognised in clinical practice but has never been evaluated and outcomes described if breast feeding is continued.Objective: We conducted a novel retrospective analysis to evaluate the biochemical and radiological outcomes of breast milk-induced hypercalcaemia. Methods: A multi-site retrospectiv...

Objective: To describe outcomes among children with hypophosphatasia (HPP) receiving asfotase alfa.Methods: This prospective, real-world study used data from all children with HPP receiving asfotase alfa in the UK Managed Access Agreement (MAA) to assess functional, health-related quality-of-life, and safety outcomes. Visits occurred at MAA enrolment, 3 and 6 months after enrolment, and every 6 months thereafter. Assessm...

Introduction: Paediatric obesity is a growing concern for the health service. There is currently no consensus for routine screening of metabolic profiles and medical treatment in obese paediatric patients.Aims/methods: We aimed to determine medium-term outcomes of Metformin treatment on BMI, glucose and insulin levels in obese paediatric patients. In a retrospective review, data were collected from obese paediatric patients on Metformin for insulin resis...

Background: Congenital hyperinsulinism (CHI) can cause severe hypoglycaemia with consequent adverse neurodevelopment. Continuous glucagon infusion (CGI) through intravenous and subcutaneous routes has been utilised to achieve glycaemic stability, but the efficacy has not been reported systematically in a CHI cohort.Aim: We aimed to investigate the efficacy and safety profile of CGI in the management of hypoglycaemia due to CHI.Meth...

Introduction: There is limited data on the psychological sequelae of obesity in paediatric patients.Aims/methods: We aimed to assess the prevalence of psychological comorbidities in obese paediatric patients. Internationally validated self-report questionnaires were offered to 19 patients and their parents from a tier three paediatric obesity clinics. These included the Paediatric Index of Emotional Distress (PI-ED); Beck Youth Inventory exploring self-p...

Background: Harrington et al.1 suggest that basal LH of ≥0.3 IU/l as measured by ICMA (Immulite 2500) has 100% specificity and 90.5% sensitivity in identifying progressive central precocious puberty (CPP).Aims: To examine the utility of basal LH measured with the DELFIA assay for identifying CPP in girls.Methods: All girls under age 9 years (median 7.3 years) investigated for precocious puberty with a GnRH...

Background: The standard dose Synacthen test (SDST) is commonly used to identify glucocorticoid deficiency. A subnormal SDST in young infants raises the possibility of adrenal insufficiency (AI) due to pathology such as congenital adrenal hyperplasia (CAH). A physiological delay in maturation of adrenal glucocorticoid secretion may be another explanation especially in asymptomatic infants with a transiently subnormal SDST.Aims: To review the diagnoses an...

Adrenal insufficiency (Adr-I) and congenital adrenal hyperplasia (CAH) are important conditions requiring specialist attention and management. Recent CAH genotype–phenotype studies have linked mutations with enzyme functioning and disease severity. Accurate diagnosis for the cause of adrenal insufficiency and the genetic cause of CAH is vital as it impacts management and prognosis.Methods: We audited patients with Adr-I and CAH seen in outpatients f...
