A case of primary aldosteronism and Hashimoto’s thyroiditis – complicated relationship or pure coincidence?

Samarasinghe Suhaniya , Martineau Marcus

Aldosterone is a steroidal hormone that specifically binds to the mineralocorticoid receptor (MR). Production and secretion of aldosterone is triggered by changes in blood pressure (BP). Primary aldosteronism (PA) is an important cause of secondary hypertension. The effects of aldosterone have been described in renal and vascular tissue but recent studies have shown that MR is also expressed in non- epithelial cells such as those of the immune system. A 29-year-old Afro-Carrib...

Case report – severe metabolic acidosis secondary to starvation ketoacidosis

Samarasinghe Suhaniya , Oddie Philip , Millar Kate , Kaushal Rashmi

During starvation, ketone bodies acetoacetate and 3-D-hydroxybutyrate are freely soluble energy substrates made by the liver. Their major role is to supply an alternative glucose substrate for the brain under conditions of medium- and long-term energy restriction. The most common cause of pathological ketoacidosis is poorly controlled type 1 diabetic mellitus triggering uncontrolled hyperglycaemia. Other common causes are alcoholic ketoacidosis and fasting ketosis. In non-diab...

A rare case of Buprenorphine patch induced central adrenal insufficiency

Chok Yin Ling , Banu Zeenat , Gannon David

Case history: A 39-year-old lady first presented to our endocrine outpatient clinic in September 2014 when blood tests at her GP surgery showed serum cortisol of 65 nmol/l.
