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...

BACKGROUND: Sodium thiosulfate is an antioxidant shown in preclinical studies in animals to prevent cisplatin-induced hearing loss with timed administration after cisplatin without compromising the antitumour efficacy of cisplatin. The primary aim of this study was to assess sodium thiosulfate for prevention of cisplatin-induced hearing loss in children and adolescents. METHODS: ACCL0431 was a multicentre, randomised, open-label, phase 3 trial that enrolled participants at 38 participating Children's Oncology Group hospitals in the USA and Canada...

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...

AIMS: Although hypokalaemia is common among patients with heart failure (HF), the prognostic significance of baseline hypokalaemia and hypokalaemia during follow-up in HF patients receiving a mineralocorticoid receptor antagonist (MRA) remains uncertain. METHODS AND RESULTS: Results of the EMPHASIS-HF trial in patients (n = 2737) with HF and reduced EF with mild symptoms, randomized to eplerenone or placebo, were analysed with regard to the presence or occurrence of hypokalaemia (serum K(+) <4...

We present a case of a 77 year-old gentleman with previous coronary artery bypass grafting, admitted to hospital with recurrent torsades de pointes (TdP) due to abiraterone-induced hypokalaemia and prolonged QTc. The patient was on abiraterone and prednisone for metastatic prostate cancer. He required multiple defibrillations for recurrent TdP. Abiraterone is a relatively novel drug used in metastatic prostate cancer and we discuss this potential adverse effect and its management in this unusual presentation...

BACKGROUND: Pregnancy toxaemia (PT) is a disease that affects pregnant goats during their last month of gestation and is characterized by a high case fatality rate. This study involved 32 does maintained on a commercial dairy goat farm that were diagnosed with PT. A physical examination was performed on and haematology parameters obtained from each doe, at the time of diagnosis. The data from the 24 PT goats that died was compared with the corresponding data from the 8 PT goats that survived...

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...

Gitelman syndrome (GS) is a rare autosomal recessive salt-losing tubulopathy. The incidence of Gitelman syndrome is 25 cases in 1 million among western population. This patient presented with loose stool, vomiting and sudden onset quadriparesis. Investigations revealed hypokalaemia, metabolic acidosis, hypomagnesaemia, hypocalciuria, hypermagnesuria. Symptoms and hypokalemia improved after starting oral magnesium and potassium supplements. But the patient again presented with symptomatic hypokalemia and delivered a still born foetus with hydrocephalus...

The estimation of potassium in the serum is basis for the diagnosis of potassium disturbances. The value is a result of intake, excretion and internal distribution of potassium between intra- and extracellular compartments of the body. Clinically, we often see disturbances of potassium. The causes are explained by an aging population with morbidities that warrant diuretic treatment on the one side, and chronic kidney diseases on the other. In the first cases, we see hypokalaemia, in the latter hyperkalaemia...

AIM: Bartter syndrome is an autosomal recessive inherited disease in which patients present with hypokalaemia and metabolic alkalosis. We present two apparently non-related cases with antenatal Bartter syndrome type I, due to a novel variant in the SLC12A1 gene encoding the bumetanide-sensitive sodium-(potassium)-chloride cotransporter 2 in the thick ascending limb of the loop of Henle. METHODS: Blood samples were received from the two cases and 19 of their relatives and deoxyribonucleic acid was extracted...

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.

BACKGROUND: Radiofrequency ablation (RFA) is an emerging treatment for primary aldosteronism owing to aldosterone-producing adenoma. Whether RFA could be an alternative treatment to laparoscopic adrenalectomy is unknown. METHODS: This was a retrospective comparative study in patients with aldosterone-producing adenoma undergoing either laparoscopic adrenalectomy or CT-guided percutaneous RFA between 2004 and 2012. Short-term outcomes and long-term resolution rates of primary aldosteronism (normalized aldosterone to renin ratio), hypokalaemia and hypertension (BP lower than 140/90 mmHg without antihypertensive medical therapy) were evaluated...

In the 'older' literature, a definitive renal pathology was described in patients with long-standing hypokalaemia and depletion of the body's potassium reserves. The topic is relevant because possibly a quite cheaply reversible element in the course of chronic kidney disease progression could be addressed. Earlier, pathologists drew attention to vacuolar changes in renal tubular epithelium accompanied by inflammatory interstitial changes in patients with potassium losses. The diagnostic term 'kaliopenic nephropathy' was coined to describe such patients...

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...

Primary hyperaldosteronism is one of the most common causes of secondary hypertension but clear differentiation between its various subtypes can be a clinical challenge. We report the case of a 37-year-old African-American woman with refractory hypertension who was admitted to our hospital for palpitations, shortness of breath and headache. Her laboratory results showed hypokalaemia and an elevated aldosterone/renin ratio. An abdominal CT scan showed a nodule in the left adrenal gland but adrenal venous sampling showed elevated aldosterone/renin ratio from the right adrenal vein...

We present a case of a 33-year old man who complained of weakness, fever and decreased urinating. A personal history revealed a consumption of creatine, protein supplements, soft drinks containing caffeine and stevia, and extreme physical activity which included lifting of heavy weights. The patient developed anuria, uraemia, fatigue, rhabdomyolysis and paradoxical hypokalaemia. After the patient had seven successive dialysis treatments, normal kidney function was restored. The report presents the first case of acute renal failure followed by hypokalaemia due to the combined action of the excessive consumption of supplements, soft drinks with stevia and caffeine, and extreme physical activity...
