title: [Trial for digitalis withdrawal in hemodialysis patients].
abstract: The indication for digitalis treatment was investigated in a controlled and prospective study lasting 12 months in 110 patients on long-term haemodialysis. In ten patients, digitalis was needed because of tachyarrhythmia due to atrial fibrillation and in five because of recurrent pulmonary edema. In 57 patients receiving digitoxin, therapy was discontinued for 4 to 6 weeks, whereas 13 patients not yet treated with digitalis, received digitoxin for 4 weeks. Without digitoxin, trial fibrillation occurred in 4 patients, while no patient experienced atrial fibrillation with digitoxin (P = 0.002). In 13 patients, radiological findings (heart enlargement, pulmonary congestion) were better with digitoxin than without. Thus digitoxin appeared to be clearly indicated in 29% of the haemodialysed patients. Additionally, digitalis was indicated in 31 patients because of heart enlargement, pulmonary congestion and (or) previous pulmonary edema. Initially, 76% of the patients were receiving digitoxin, whereas, after the investigation, the rate was only 57% (P less than 0.001). The prospective frequency of clinically apparent digitoxin intoxication was low (3%) and so were the overall toxic plasma digitoxin levels (5%). Digitalis should be given deliberately but not restrictively to haemodialysis patients, since atrial fibrillation (13%) and heart failure (50%) are frequent and often concealed.
