UNLABELLED: A 7-year-old girl presented six hours after ingestion of a yellow oleander seed (Thevetia peruviana) with severe emesis, change in colour vision and complete heart block. Initial treatment with phenytoin and isoprenalin infusion led to intermittent supraventricular and ventricular tachycardia. The patient was then treated with two intravenous doses of 190 mg of digoxin-specific Fab antibody fragments (Digibind). Subsequently the patient's rhythm reverted to sinus rhythm and the symptoms resolved within 2 hours. CONCLUSION: administration of digoxin-specific Fab antibody fragments in an otherwise healthy child after oleander intoxication is safe and without adverse reactions.
In a series of papers the authors analyze literature data on the use of cardiac glycosides for long term treatment of chronic heart failure. Part 1 is devoted to clinical pharmacology of glycosides with special emphasis on digoxin. In low doses digoxin produces no substantial effect on contractility of left ventricular myocardium but can cause worsening of its diastolic function. Favorable action of digoxin on clinical course and outcomes of chronic heart failure is most probably related to modulation of neuro-humoral systems. Data on factors influencing sensitivity to glycosides in various categories of patients with heart failure, their interaction with other drugs, and contraindications for digoxin are also presented.
In a series of papers the authors analyze literature data on the use of cardiac glycosides for long term treatment of chronic heart failure. Data obtained in prospective placebo controlled trial DIG show that digoxin significantly increases mortality of all patients with sinus rhythm and intact left ventricular systolic function (ejection fraction > 45%) and of women with left ventricular systolic dysfunction (ejection fraction < or = 45%). Men with left ventricular systolic dysfunction represent the only category of patients with chronic heart failure in sinus rhythm in whom long term administration of digoxin is justified. Digoxin does not affect mortality of these patients however it reduces requirements in hospitalizations due to worsening of heart failure.
