Exercise tolerance improves with erythropoietin

11 transfusion-dependent patients with chronic renal failure who required regular haemodialysis received IV erythropoietin (EPO) 100 U/kg 3 times weekly increased by 50 U/kg every 3 weeks to a maximum of 200 U/kg or until haemoglobin levels increased by ~ 5% of the level at the beginning of the trial. Maintenance levels were then individually adjusted.

All 11 patients became independent of blood transfusions and 6 patients achieved haemoglobin levels of ~ 100 gil. Four patients failed to reach target haemoglobin levels, these patients had significantly higher serum aluminium concentrations than fully responding patients . Combined therapy with EPO and deferoxamine [desferrioxamine] in these patients resulted in target haemoglobin levels within 4 weeks. EPO dose was reduced steadily in these 4 patients and 2 patients were eventually maintained on deferoxamine only. Thrombocyte counts increased within 2 weeks of the initiation of therapy and remained stable, below normal limits, for 30 weeks of treatment. Ferritin levels significantly decreased in all but 1 patient within 4 weeks of the onset of EPO therapy, and fell steadily throughout the treatment period.

Aerobic capacity and oxygen uptake were significantly improved with EPO therapy and maximum HR decreased. Lean body mass increased and fat mass decreased, but body weights remained constant.

Reported adverse effects Included rash and fever in 1 patient, which recurred with every EPO dose and also when the vehicle only was tested, transient cerebral ischaemic attack in a patient with general arteriosclerosis and hypertensive encephalopathy in 1 patient. Patients with hypertension prior to the study required intensified therapy and 1 patient developed hypertension which was controlled by therapy. Rosenlal K. GronhagerHlska c. SOVllarVI A.
