Introduction: Insulin stress test (IST) has long been the gold standard for testing the hypothalamus-pituitary–adrenal (HPA) axis. There are concerns about the safety of IST as hypoglycaemia can give rise to various symptoms including seizure and coma although this is rarely seen in clinical practice. Hyperinsulinaemic hypoglycaemic clamp is a common research procedure used to induce hypoglycaemia in a step-wise fashion to study the effect of hypoglycaemia.<p class="a...

Hydrocortisone day curves, Salivary cortisols, timed urinary free cortisols and 24 hour urine cortisols have been used to estimate hydrocortisone replacement in hypoadrenal patients.We looked at 39 patients who had hydrocortisone day curve estimations in our hospital. 35 of those patients had simultaneous 24 hour urine free cortisol estimation. All hypothyroid patients were on adequate replacement dose of thyroxine.The commonest cl...

Introduction: The study aim was to compare serial Short Synacthen test (SST) results to diagnose secondary Adrenal Insufficiency (AI) in patients with confirmed pituitary diseases.Methods: Serial SST results of patients, tested between 2006 and 2018 in the department of Diabetes and Endocrinology, at a tertiary centre, were reviewed retrospectively. Patient details were obtained from local dynamic test database, maintained by Endocrine Nurse Specialist. ...

The current paradigm for management of acromegaly includes surgery as primary treatment regardless of whether or not this is likely to be curative. There is increasing evidence that somatostatin analogue medical therapy may produce shrinkage of growth hormone producing pituitary tumours. This study tests the hypothesis that primary medical therapy may produce clinically significant tumour shrinkage prior to surgery.Eleven treatment naïve subjects wi...

Background: Growth hormone (GH) excess is associated with increased insulin resistance (IR). Lanreotide autogel (Autogel) reduces GH-levels effectively in patients with active acromegaly. However, the effect of somatatostatin analogues on IR and (-cell function (HOMA %B) is complex and unpredictable. Our study prospectively monitored IR and related metabolic parameters in acromegalics treated with Autogel.Methods: Nine patients (P) with active acromegaly...

Introduction: Radiotherapy is an important adjuvant treatment for pituitary and cranial diseases. The aim of the study was to observe response of Radiotherapy (RTX) on Hypothalamic–Pituitary–Adrenal (HPA) axis determined by serial Short Synacthen tests (SSTs). Methods: Patients treated with adjuvant Cranial Radiotherapy between the years 2000 and 2018 in the department of Radiation Oncology and who also underwent serial Short Synacthen tests, i...
