title: Effectiveness of low-dose erythropoietin in predialysis chronic renal failure patients.
abstract: Recombinant human erythropoietin (rHuEpo) has been shown to be both effective and usually safe in patients with chronic renal failure who have not yet reached the stage requiring dialysis. There are, however, disturbing reports on the possibility of deterioration of the reserve renal function in association with rHuEpo therapy. Most of the published studies have used rHuEpo in doses of 50-150 U/kg three times weekly subcutaneously. An open-label trial of rHuEpo therapy was conducted on 21 patients with chronic renal failure treated sequentially at a referral hospital, rHuEpo was used in doses of 50 U/kg twice weekly for 4 weeks followed by 25 U/kg twice weekly for 8 weeks subcutaneously, a regimen substantially lower than current recommendations. This was associated with a gentle but significant increase in haematocrit (P < 0.05) and haemoglobin (P < 0.05), while the serum creatinine and the reciprocal of the creatinine remained stable, with a tendency to improve rather than worsen (P = 0.06). We conclude that there is no need to aim at a rapid increase in haematocrit and haemoglobin by rHuEpo therapy; rather a gentle increase using modest doses is both effective and safe.
