Introduction: The short Synacthen test (SST) is a popular diagnostic investigation for adrenal insufficiency (AI). Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. Salivary cortisol is a well-established alternative to serum sampling. We have developed a non-invasive alternative to the 1 μg SST, using a novel formulation of Synacthen (with a nasal drug enhancer, chitosan) given nasally and utilising saliva to measure t...

Introduction: A 2009 BSPED survey revealed that 90% use a low dose Synacthen test (LDST) and 44% had noticed increased referrals of asthmatic children prescribed inhaled corticosteroids (ICS). Approximately 21% of UK children have asthma of whom 70% are prescribed ICS (10% at ‘high dose’). There is an increasing need for a simple, less invasive, alternative to the LDST to evaluate their adrenal function. We are developing a non-invasive LDST, with Synacthen administe...

Background: Replacing physiological cortisol levels is important for the long-term health of patients with adrenal insufficiency and congenital adrenal hyperplasia (CAH). Modified-release formulations of hydrocortisone are one strategy being used to replace the cortisol circadian rhythm in adult patients but there is no data in children. Physiologically based pharmacokinetic (PBPK) modelling is a valuable tool for paediatric drug development1; however, there are no ...

Introduction: Worldwide the Short Synacthen Test (SST) is the most popular investigation for adrenal insufficiency (AI). Its invasivity make it resource-intensive. Salivary cortisol is a well-established alternative to serum. We have developed a non-invasive alternative to the SST, using a novel formulation of Synacthen (containing a drug enhancer, chitosan) administered nasally and utilising saliva to measure glucocorticoid response.Methods: Four open-l...
