Haemoglobin and Serum Iron Responses to Periodic Intravenous Iron-Dextran Infusions during Maintenance Haemodialysis

Abstract

Patients with chronic renal failure who were on maintenance haemodialysis, were given monthly 600 mg iron intravenously as iron-dextran complex to a body replacement total of 5-6 g iron. Those patients who had been on maintenance haemodialysis for a long period and had received numerous blood transfusions failed to show a rise in haemoglobin levels. Those patients who received iron from the commencement of maintenance dialysis, and who had not received blood transfusions, showed a significant increase in haemoglobin concentrations which has been maintained for more than 18 months after iron therapy ceased, despite a concurrent decrease in serum iron concentrations. Pre-treatment and post-treatment levels of serum iron are not of predictive value for the success of iron treatment, neither for the haemoglobin nor the serum iron response. A body replacement dose of iron given intravenously over a year benefits the majority of patients on maintenance haemodialysis and is recommended for the treatment of their anaemia.
