OBJECTIVE To examine the safety of using aliskiren combined with agents used to block the renin-angiotensin system. DESIGN Systematic review and meta-analysis of randomised controlled trials. DATA SOURCES Medline, Embase, the Cochrane Library, and two trial registries, published up to 7 May 2011. STUDY SELECTION Published and unpublished randomised controlled trials that compared combined...

Whereas the adequate intake of potassium is relatively high in healthy adults, i.e., 4.7 g per day, a dietary potassium restriction of usually less than 3 g per day is recommended in the management of patients with reduced kidney function, especially those who tend to develop hyperkalaemia including patients who are treated with angiotensin pathway modulators. Most potassium-rich foods are cons...

Acidic ostreolysin A/pleurotolysin B (OlyA/PlyB, formerly known as ostreolysin (Oly), and basic 20 kDa equinatoxins (EqTs) are cytolytic proteins isolated from the edible mushroom Pleurotus ostreatus and the sea anemone Actinia equina, respectively. Both toxins, although from different sources, share many similar biological activities: (i) colloid-osmotic shock by forming pores in cellular and ...

More than a decade ago the first large randomized controlled trial studying the effects of spironolactone in heart failure patients was published. The Randomized Aldactone Evaluation Study (RALES) trial showed for the first time the robust effects of aldosterone receptor blockers on reducing mortality. In this landmark trial patients with systolic heart failure in New York Heart Association (NY...

Surreptitious hyperkalaemia is not a common problem, particularly in patients not yet dialysis dependent. We encountered a patient who baffled her physicians and their consultants, who nonetheless proposed life-saving treatments and novel explanations. However, according to the maxim that common things are common and rare things are rare, we solved the problem by focusing on the accompanying an...

Generally, cardiac arrest due to pulseless electrical activity has a poor outcome, except when reversible factors such as acute hyperkalaemia are identified and managed early. Hyperosmolar diabetic non-ketotic coma may lead to acute hyperkalaemia. Hyperosmolar diabetic non-ketotic coma is a metabolic emergency usually seen in elderly non-insulin dependent diabetics, characterized by severe hype...

Extreme hyperkalaemia is a life-threatening electrolyte disorder. It is relatively common in patients with severe renal insufficiency. This report describes a case of extreme hyperkalaemia caused by drugs in an 82-year-old female patient without severe renal insufficiency, who was successfully treated without haemodialysis. The patient had been treated for arterial hypertension and type 2 diabe...
