BACKGROUND: Digoxin is a cardiac glycoside that is frequently prescribed in atrial fibrillation and heart failure. Symptoms such as nausea, hyperkalaemia, cardiac arrhythmias and cardiac arrest are seen in digoxin toxicity. The treatment focuses on reduction of digoxin absorption, prevention of hypokalaemia and hyperkalaemia, treatment of symptoms and, in severe toxicity, administration of digoxin antibodies. CASE DESCRIPTION: A 73-year-old man with a history of extensive cardiac disease was seen 45 minutes after ingesting 20 mg of digoxin...

Anorexia nervosa (AN) is a serious psychiatric disorder which typically occurs in young women; however, more and more cases in middle-aged women are being reported. The management of this complex disease requires a team approach, and full recovery occurs only in 50% of patients. Endocrine and metabolic complications are commonly observed, the latter of which may even be life-threatening, and require prompt and proper management. Infections, albeit reported, are not usually a major clinical problem in these patients...

A 58-year-old Chinese woman with well controlled type 1 diabetes mellitus presented with acute and progressive bilateral lower limb weakness. Investigations revealed severe hypokalaemia (1.3 mmol/L) and hypophosphataemia (<0.32 mmol/L) with rhabdomyolysis and electrocardiogram changes, without other concurrent biochemical abnormalities. Immediate intravenous and oral potassium and phosphate replacement was initiated with objective improvement in weakness with replenished electrolyte levels. Urine studies confirmed renal potassium wasting...

BACKGROUND: Gitelman syndrome (GS) is an autosomal recessive renal tubular disorder characterised by renal salt wasting with hypokalaemia, metabolic alkalosis, hypomagnesaemia and hypocalciuria. It is caused by mutations in SLC12A3 encoding the sodium-chloride cotransporter on the apical membrane of the distal convoluted tubule. We report a South African family with five affected individuals presenting with hypokalaemia and unusual food cravings. METHODS: The affected individuals and two unaffected first degree relatives were enrolled into the study...

We describe the first case of distal renal tubular acidosis (dRTA) associated with primary sclerosing cholangitis. A 26-year-old Lao-Thai male patient presented with severe jaundice, metabolic acidosis and hypokalaemia. He was diagnosed of dRTA. Liver transplantation resulted in correction of electrolyte disturbances and hyperbilirubinaemia. A fludrocortisone-furosemide test revealed normal urinary acidification, demonstrating no residual dRTA. This observation suggests that dRTA may be an early manifestation of bilirubin-associated nephropathy or the consequence of an immune mechanism...

WHAT IS KNOWN AND OBJECTIVE: Prescription sequence symmetry analyses (PSSA) is a ubiquitous tool employed in pharmacoepidemiological research to predict adverse drug reactions (ADRs). Several studies have reported the advantage of PSSA as a method that can be applied to a large prescription database with computational ease. The objective of this study was to validate New Zealand (NZ) prescription database as a potential source for identifying ADRs using the PSSA method. METHODS: We analysed de-identified individual-level prescription data for people aged 65 years and above for the period 2005 to 2014 from the pharmaceutical collections supplied by the NZ Ministry of Health...

We present the case of a female patient aged 39 years who was admitted to our hospital due to hypertension, severe hypokalaemia and metabolic alkalosis; physical examination was remarkable for plethoric moon face, centripetal obesity and bilateral lower extremity oedema. She was admitted for intravenous potassium replacement and further assessment of hypertension and associated clinical findings. Laboratory testing showed increased levels of aldosterone, renin, cortisol, testosterone and androstenedione. An abdominal CT revealed a large mass in the right adrenal gland with hepatic involvement...

Hypokalaemia is a common clinical problem. It can lead to severe disturbances in cardiac, neurological and muscle function. We present the case of a 45-year-old woman who was transported to our hospital with cardiac arrest following ventricular fibrillation. Blood sampling revealed severe acidosis (pH 7.02) and extreme hypokalaemia (0.9 mmol/l). The low serum potassium level was most likely caused by the combination of a very deficient diet and use of a thiazide diuretic. She never reported any symptoms. An acute intracellular shift of potassium due to epinephrine and perhaps also the cathecholamines in Red Bull may have further decreased the serum potassium concentration...

Hypokalaemia as a typical feature of primary aldosteronism (PA) is associated with muscle weakness and could contribute to lower cardiopulmonary fitness. The aim of this study was to describe cardiopulmonary fitness and exercise blood pressure and their determinants during a symptom-limited exercise stress test in patients with PA. We performed a cross-sectional study of patients with confirmed PA who were included before adrenal vein sampling on whom a symptom-limited exercise stress test with expired gas analysis was performed...

Ondansetron is widely used in general practice for nausea and vomiting due to any cause. We report a rare side effect, life-threatening hypokalaemia following intravenous Ondansetron injection. It may be judicious to restrict the use of Odansetron to patients with severe vomiting due to chemotherapy or in post-operative state. Life-threatening hypokalemia can occur without any warning and may be difficult to manage in a primary set up.

AIMS: Diuretic treatment is often needed in acute heart failure following myocardial infarction (MI) and carries a risk of abnormal potassium levels. We examined the relation between different levels of potassium and mortality. METHODS AND RESULTS: From Danish national registries we identified 2596 patients treated with loop diuretics after their first MI episode where potassium measurement was available within 3 months. All-cause mortality was examined according to seven predefined potassium levels: hypokalaemia <3...

REVIEW
E S Kim, Emma D Deeks
Patiromer (Veltassa(™)) for oral suspension is a sodium-free potassium binder that is approved in the USA for the treatment of hyperkalaemia. In clinical trials, patiromer significantly reduced serum potassium levels from baseline to week 4 in patients with chronic kidney disease (CKD) and mild to severe hyperkalaemia (OPAL-HK), or CKD, mild to moderate hyperkalaemia and type 2 diabetes mellitus (AMETHYST-DN), who were receiving renin-angiotensin-aldosterone system inhibitors (RAASis; drugs that inhibit the renal excretion of potassium)...

This case report describes the possible benefit of intravenous lipid emulsion in two patients surviving a severe intoxication with hydroxychloroquine in a dose that was previously considered to be lethal. The first case involves a 25-year-old female who ingested 17.5 grams of hydroxychloroquine, approximately one hour before presentation. An ECG showed QRS widening and the lab results showed hypokalaemia. She became unconscious, and developed hypotension and eventually apnoea. After intubation, supportive care consisted of norepinephrine and supplementation of potassium...

QUESTIONS UNDER STUDY: Hypokalaemia in inpatients is common, and is associated with morbidity and mortality. Its management is risky and not always effective. We launched an educational programme with the aim of increasing the rate of potassium normalisation during hospital stay, and of reducing unmonitored cases. METHODS: The project consisted of three phases: (I) retrospective analysis on 26 471 patients hospitalised in 2012 in five acute care hospitals of southern Switzerland (Ente Ospedaliero Cantonale, EOC) with identification of improvement goals on a sample survey (588 cases of hypokalaemia); (II) revision of internal guidelines, and implementation of educational activities in one of the five hospitals (Ospedale Regionale di Locarno, ODL); (III) follow-up analysis on the 26 726 patients hospitalised in 2014 and second sampling to complete the evaluation of the efficacy of the intervention...

Bartter syndrome (BS) is a hereditary disease, with an autosomal recessive or autosomal dominant mode of transmission. It is characterized by salt wasting hypochloraemic, hypokalaemic metabolic alkalosis and hyperreninaemia with normal blood pressure. The primary defect is in the thick ascending limb of loop of Henle (TAL). Herein, we report a case that had typical features of BS like severe dehydration, severe hypokalaemia, metabolic alkalosis and failure to thrive but had normal aldosterone level which is very uncommon...

UNLABELLED: McKittrick-Wheelock syndrome (MWS) is a rare consequence of severe dehydration and electrolyte depletion due to mucinous diarrhoea secondary to a rectosigmoid villous adenoma. Reported cases of MWS commonly describe hypersecretion of mucinous diarrhoea in association with dehydration, hypokalaemia, hyponatraemia, hypochloraemia and pre-renal azotemia. Hyperglycaemia and diabetes are rarely reported manifestations of MWS. Herein we describe the case of a 59-year-old woman who presented with new-onset diabetes and severe electrolyte derangement due to a giant rectal villous adenoma...

BACKGROUND: Many studies have demonstrated that subarachnoid haemorrhage (SAH) is associated with hyponatraemia but associations with potassium levels are less well studied. There is a clear physiological link between sodium and potassium and abnormal potassium levels that can lead to dangerous outcomes. The purpose of the present study is to define changes in levels of both these cations that occur in standardised salt management of SAH. METHOD: 114 records of patients admitted between 2 January 2011 and 27 December 2011 with SAH at a single institution were obtained retrospectively...

Secondary hypertension occurs in a significant proportion of adult patients (~10%). In young patients, renal causes (glomerulonephritis) and coarctation of the aorta should be considered. In older patients, primary aldosteronism, obstructive sleep apnoea and renal artery stenosis are more prevalent than previously thought. Primary aldosteronism can be screened by taking morning aldosterone and renin levels, and should be considered in patients with severe, resistant or hypokalaemia-associated hypertension. Symptoms of obstructive sleep apnoea should be sought...

KEY POINTS: STE20 (Sterile 20)/SPS-1 related proline/alanine-rich kinase (SPAK) and oxidative stress-response kinase-1 (OSR1) phosphorylate and activate the renal Na(+) -K(+) -2Cl(-) cotransporter 2 (NKCC2) and Na(+) Cl(-) cotransporter (NCC). Mouse models suggest that OSR1 mainly activates NKCC2-mediated sodium transport along the thick ascending limb, while SPAK mainly activates NCC along the distal convoluted tubule, but the kinases may compensate for each other. We hypothesized that disruption of both kinases would lead to polyuria and severe salt-wasting, and generated SPAK/OSR1 double knockout mice to test this...

BACKGROUND: Several expression array studies identified molecular apocrine breast cancer (BC) as a subtype that expresses androgen receptor (AR) but not estrogen receptor α. We carried out a multicentre single-arm phase II trial in women with AR-positive, estrogen, progesterone receptor and HER2-negative (triple-negative) metastatic or inoperable locally advanced BC to assess the efficacy and safety of abiraterone acetate (AA) plus prednisone. PATIENTS AND METHODS: Patients with a metastatic or locally advanced, centrally reviewed, triple-negative and AR-positive (≥10% by immunohistochemistry, IHC) BC were eligible...
