Menopause timing is highly variable, having a direct effect on reproductive lifespan, fertility and health outcomes in later life. Endocrine and imaging tests only record changes in ovarian function that have already taken place, thus disabling early prediction and identification of women with reduced reproductive lifespan. Human genetic studies have attempted to overcome this problem by identifying genetic markers associated with menopause timing and fertility. Using data fro...

Introduction: First-line treatment for congenital adrenal hyperplasia (CAH) is hydrocortisone1. When adequate control is not achieved, prednisolone (or its prodrug prednisone) are often used. However, there has been no formal comparison of disease control in CAH comparing prednis(ol)one vs hydrocortisone and patients are often on a glucocorticoid dose that exceeds the guideline recommended dose of hydrocortisone (≤25 mg/day)1,2. We report an interim...

Background: Patients with classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD-CAH) have poor health outcomes due to failure of currently available glucocorticoid preparations to control adrenocorticotropic hormone-driven androgen excess. We investigated whether modified-release hydrocortisone (MR-HC), which mimics the physiological circadian cortisol rhythm, could improve androgen control.Methods: 122 patients with 21-OHD-CAH ...

Background: Modified-release hydrocortisone (MRHC) capsules (Efmody, Diurnal Ltd, Cardiff, UK), have been developed to replicate the cortisol diurnal rhythm and shown to improve CAH disease control1. We have examined relative bioavailability of MRHC and disease control of congenital adrenal hyperplasia (CAH) patients switched from standard therapy to MRHC.Methods: An open label, randomised, 2 period, crossover study comparing the relative bioavailability...
