Background: Hydrocortisone day curves (HCDCs) are commonly used to assess hydrocortisone replacement for patients with adrenal insufficiency (AI).Methods: HCDCs were obtained for 216 adrenally insufficient patients between 2004 and 2012 at Imperial College Healthcare NHS Trust. The area under the curve (AUC) was calculated for each patient’s day profile. Lipid profiles and glycated haemoglobin (HbA1c) values were recorded for each patient at both th...

Background: Glucocorticoid-induced osteoporosis is one of the major clinical concerns of long-term steroid treatment. Previous studies have shown that immunosuppressive doses of glucocorticoid can lead to osteoporosis. This study investigated whether there is a relationship between cortisol exposure and the development of osteoporosis in patients receiving replacement doses.Methods: Hydrocortisone day curves (HCDCs) performed a...

Case history: An asymptomatic 26-year-old female was found to have hypercalcaemia with an associated normal PTH and vitamin D deficiency on blood tests in primary care. She was referred to the endocrinology clinic for further assessment. There was no history of renal calculi, constipation or fractures. The patient was taking the combined oral contraceptive pill only. There was a family history of hypercalcaemia, with an uncle affected in his 50s and a first cousin in his 20s. ...

Prednisolone is widely prescribed in the UK, whereas prednisone is used instead for the same indications in the United States. Both have utility as anti-inflammatory agents and for use as glucocorticoid replacement therapy at lower doses. Oral prednisone is converted to prednisolone by first pass hepatic metabolism by 11 beta HSD-1. This study was undertaken to compare the bioavailability of prednisone against prednisolone. To determine the conversion of prednisone to predniso...

Background and Aim: Type 2 diabetes mellitus (T2DM) disparately affects ethnic groups. Prevalence is higher in Asian and Black ethnicities, and these patients suffer increased rates of some diabetes-related complications. Bariatric surgery is an effective treatment for T2DM and can lead to complete diabetes remission. The aim of this study was to assess if T2DM remission rates at 1-year following bariatric surgery vary between different ethnicities.Metho...

Introduction: Obesity-associated psychopathological co-morbidities have a negative impact on quality of life. Roux-en-Y gastric bypass surgery (RYGB) has been shown to ameliorate psychological health, however, the underlying mechanisms are not fully understood. Changes in gastrointestinal and central neuroendocrine signalling have been postulated as mediators of psychological and eating behaviour changes following RYGB. Here we assess the impact of subcutaneous infusions of th...

Background: Prednisolone is used for glucocorticoid replacement therapy in Adrenal Insufficiency. Package inserts indicate that prednisolone should be administered with or after food as there is a belief that prednisolone causes stomach ulcers. We have investigated the impact of various fasted and non-fasted states on its pharmacokinetic profile.Method: A healthy volunteer provided three 4 mg prednisolone profiles. The first was a fasted reference curve....

Background: The cortisol circadian rhythm has an early morning peak with an increase before awakening, and a second lunchtime peak. Using a UPLC-MS/MS technique to measure prednisolone, the active metabolite of prednisone, we investigated the suitability of modified release (MR) prednisone (Lodotra) as a replacement therapy.Method: Blood samples were taken at fixed time points after the administration of MR-prednisone. Concentrations of the active metabo...
