- Abstract
To examine the suggestion that s.c. administration of recombinant human erythropoeitin (rHuEpo) may be more effective than i.v. administration, we changed the route of administration in 11 patients, previously established on a stable dose of rHuEpo given twice or thrice weekly, from i.v. to s.c. administration without altering the dose. All patients were iron replete (serum ferritin> 100μg/1). In one patient the haemoglobin concentration declined at the time of conversion due to poor compliance, and another patient died shortly after conversion. In the remainder there was a significant increase in haemoglobin concentration from 9.30 (SD 0.78) at the time of conversion to 9.84 (0.59) at 1 month, 10.35 (1.22) at 2 months, and 10.39 (1.42) at 3 months. The increase in haemoglobin concentration was greater than 1 g/dl at 3 months in only five of the patients. Serum ferritin prior to conversion was similar in ‘responders’ and ‘non-responders’, but all responders had a transferrin saturation of > 16%, whereas three of four non-responders had transferrin saturation of ≤16%. Subcutaneous administration of rHuEpo is more effective, dose for dose, than i.v. administration, but poor iron mobilization may limit the response.
