Prognostic Utility of Serum Potassium in Chronic Digoxin Toxicity

Digoxin toxicity with normal digoxin and serum potassium levels: beware of magnesium, the hidden malefactor.

BACKGROUND In recent years, digoxin use has been on the decline, with decreased incidence of digoxin toxicity. Hence, digoxin toxicity, when it occurs, remains an elusive diagnosis to emergency physicians. OBJECTIVE To present a case of digoxin toxicity with normal levels of digoxin and serum potassium, but with severe hypomagnesemia. CASE REPORT A 66-year-old woman presented with junctiona...

Good Outcome after Digoxin Toxicity Despite Very High Serum Potassium Level

Dear Editor, Digoxin, as a cardiac glycoside extracted from the Digitalis lanata is widely used in the treatment of different heart diseases, such as atrial fibrillation, atrial flutter and heart failure. Its effect is to increase myocardial contractility while mildly prolonging the duration of contraction. The result is decreased heart rate, increased blood pressure and stroke volume, leading ...

Assessment of Abnormal Serum Digoxin Concentration

ABSTRACT Cardiac glycosides have been used in the management of heart failure for more than 200 years and remain the only drug currently available for Long-term ambulatory use that have positive inotropic effect. The relatively narrow therapeutic- index of cardiac glycosides renders them particularly difficult to use, and the clinician should have a detailed understanding of the actions and ph...

Evaluation of the utility of autologous serum skin test and the efficacy of autologous serum therapy in chronic spontaneous urticaria

Background: Autologous serum skin test (ASST) evaluates the presence of any serum histamine-releasing factors and histamine-releasing autoantibodies. Autologous serum therapy (AST) is a therapy in which repeated injections of autologous serum are administered intramuscularly for treatment of chronicspontaneous urticaria (CSU). The aim of this study is to evaluate the advantages and compare the ...
