Introduction: Congenital hypothyroidism (CH) is defined as thyroid hormone deficiency which is present at birth. Thyroid hormones are crucial for early neurodevelopment. Untreated severe CH results in major neurological deficits. Therefore, if treatment is initiated early, these deficiencies can be prevented. Newborn screening for CH was first initiated in Sri Lanka in September 2010.Methods: A retrospective cohort study...

Introduction: ‘At risk’ groups for vitamin D deficiency have long been identified, including the chronically ill. According to guidelines published by the European Society of Endocrinology (ESPE, 2002), the American Academy of Paediatrics (AAP, 2008) and the Endocrine Society (ENDO, 2011), vitamin D levels should be measured in chronically ill or at risk patients. We aimed to test the current knowledge of these guidelines amongst consultants in a large tertiary hospi...

Background: The level of 25OH vitamin D (25OHD) which separates deficiency from sufficiency is heavily deabted. With decreasing 25OHD levels, typical biochemical derangements set in, such as increasing parathyroid hormone (PTH) and alkaline phosphatase (ALP) levels, and decreasing phosphate and calcium levels. In adults, serum concentrations of PTH reportedly start to rise when serum 25OHD levels drop below 30 μg/l. Such data are scarce in children....

Introduction: Most (89%) UK units offer some form of free patient choice for new paediatric patients commencing GH therapy. Initial data indicates that patient choice improves adherence, resulting in improved growth (height velocity) short-term.Objective: To compare outcome measures between patients offered free choice and/or hospital supply (including home services and adherence tracking assessed using ampoule counting) with GH therapy with those who di...

Introduction: Resistant starch (RS) has beneficial effects on postprandial glucose metabolism in both animals and adults. Hitherto, it has not been studied in children. The long-term effects of RS in reducing obesity and improving metabolic profiles need to be investigated in children. Objectives: Our objective was to compare serial plasma glucose, insulin, gut hormone profiles and satiety scores in obese children after meals, containing increasing amoun...

Introduction: There is no unified approach in clinical practice regarding the medical management of congenital adrenal hyperplasia (CAH), despite existent international guidance. We aimed to explore geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of patients with CAH.Methods: We collected data recorded by 33 centres from 16 countries in the I-CAH Registry. We analysed patient visits between 1982 and 2018,...

Background: In 2019, the International CAH Registry (I-CAH) performed a benchmarking exercise of acute adrenal insufficiency related adverse events including adrenal crises (AC) and sick day episodes (SDE).Methods: In 2022, I-CAH data on children aged <18 years at first visit with 21-hydroxylase deficiency CAH from 35 centres in 19 countries were analysed to examine the current occurrence of SDE and AC and compared t...

Aims: We studied the association of newborn screening (NBS) on early infancy outcomes in 21-hydroxylase deficiency (21OHD) congenital adrenal hyperplasia (CAH), using I-CAH registry data.Methods: From 2018-2023, data was available for 121 infants with 21OHD CAH (52 male) during the first 90 days of life from 26 centres in 15 countries. NBS was performed in 15 centres from 9 countries.Result...

Background: The reported occurrence and management of acute adrenal insufficiency–related adverse events in children vary widely between centres and may depend on available resources.Methods: Real world data from the I-CAH Registry from 44 centres [32 from high income (HIC) and 12 from low/middle income (LMIC) countries] and a total number of 607 children were linked to the results of a health care survey of local r...

Background: The reported occurrence and management of acute adrenal insufficiency–related adverse events in children vary widely between centres and may depend on available resources.Methods: Real world data from the I-CAH Registry that included a total of 2478 patient years follow-up on 607 children from 44 centres were studied and their association to the results of a health care survey of these centres that enqui...
