Relative potency of prorenoate potassium and spironolactone in attenuating diuretic induced hypokalaemia.

Diuretic-induced hypokalaemia and surgery: much ado about nothing?

Progressive hypokalaemia in elderly patients taking three thiazide potassium-sparing diuretic combinations for thirty-six months.

Three different thiazide potassium-sparing diuretic combinations were given to elderly patients for heart failure. Eighty patients received their allocated combinations for 3 years and had 6-monthly measurements of plasma potassium. A further 84 were recruited for study but 29 died within 6 months and 55 had to be withdrawn from the trial. The triamterene-containing preparation was discontinued...

Spironolactone and canrenoate: different antialdosteronic diuretic agents.

Plasma levels of canrenone and androgen receptoractive materials (ARM) were determined during long-term oral K-canrenoate or spironolactone therapy in cirrhotics with chronic recurrent ascites. Mean plasma canrenone level was approximately 3 times higher under K-canrenoate than under spironolactone treatment; moreover, the levels were not dose related. Either type of treatment did not affect pl...

Arrhythmogenic potential of diuretic induced hypokalaemia in patients with mild hypertension and ischaemic heart disease.

In view of evidence suggesting an association of mild hypokalaemia with cardiac arrhythmia, the arrhythmogenic potentials of potassium losing and potassium sparing diuretic treatments were compared in a controlled prospective crossover study of 10 patients with mild hypertension and ischaemic heart disease. Mean (SEM) plasma potassium was 4.3(0.06) mmol/l and 3.3(0.07) mmol/l after potassium sp...

Comparative Potency of Green Tea and Red Wine Polyphenols in Attenuating Staphylococcal Superantigen-Induced Immune Responses

Proinflammatory cytokines mediate the toxic effects of staphylococcal exotoxins (SE). This study compared the potency of two polyphenols, green tea epigallocatechin gallate (EGCG) and red wine resveratrol (RES), in blocking the pro-inflammatory effects of staphylococcal enterotoxin B (SEB) and toxic shock syndrome 1 (TSST-1). Both EGCG and RES dose-dependently inhibited superantigen-stimulated ...
