Adult CAH patients have poor health outcomes and these in part relate to the method of glucocorticoid replacement in children and adults. Life-saving glucocorticoid replacement was introduced in the 1950s and the majority of children are treated with immediate release hydrocortisone whereas adults are treated with a mixture of hydrocortisone, prednisolone, prednisone and dexamethasone from one to four times daily and in circadian and reverse circadian regimens. Despite these p...

Background: Measurement of salivary glucocorticoids is an accepted method for testing adrenal function and is gaining popularity as it offers a non-invasive collection technique, enabling sampling in the community or home environment, allowing tailored capture of steroid circadian rhythm and improved patient experience. However, there is little data on stability during home collection and sampling methods in young children. Current salivary collection techniqu...

Background: Optimisation of hydrocortisone replacement therapy remains challenging due to complex pharmacokinetics as circulating cortisol is protein bound mainly to corticosteroid-binding globulin (CBG) that has a circadian rhythm.Objective: A detailed analysis of the CBG circadian rhythm and its impact on cortisol exposure during hydrocortisone replacement therapy.Methods: CBG was measured over 24 h in 14 healthy...

Introduction: Children with congenital adrenal hyperplasia (CAH) and adrenal insufficiency (AI) rely on lifelong hormone replacement with hydrocortisone (HC). Alkindi® is the first HC licensed for children from birth to 18 years with AI, available in small doses of 0.5, 1, 2 and 5mg required for the needs of neonates, infants and children.Objectives: Primary: long-term safety of Alkindi®; Secondary: long-term d...

Introduction: Worldwide the Short Synacthen Test (SST) is the most popular diagnostic investigation for adrenal insufficiency (AI) amongst both paediatric and adult endocrinologists. Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. We have previously validated a reliably absorbed and well tolerated formulation of nasal synacthen (Nasacthin003) in healthy adult males, measuring the glucocorticoid response in salivary cortiso...

Background: Congenital adrenal hyperplasia (CAH) is a rare disorder of steroid synthesis. Patients have multiple health problems. Healthcare utilisation has not previously been assessed in the paediatric population with CAH.Objective and hypotheses: To assess healthcare resource use in patients in England with CAH.Method: The English Clinical Practice Research Datalink (CPRD) database is an observational and interventional research...

Context: Alkindi® (Hydrocortisone Granules, Diurnal Ltd, UK), was recently licensed for oral administration to children with adrenal insufficiency (AI) from birth to 18 years. Previously, children received compounded hydrocortisone to achieve age appropriate dosing, however almost 25% of batches were out of specification for mass and content uniformity and clinically evident under- and over-dosing was reported.Objectives: Primary: long-te...

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: ...

Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...
