Dose escalation induces tolerance to side-effects of erythropoietin in a patient with dialysis anaemia: Case report

A 51-year-old woman began haemodialysis for chronic renal failure in February 1981. Symptomatic anaemia required treatment with recombinant human erythropoietin (rHuEPO) in February 1990 (3000 IU, twice weekly, intravenously). She developed influenza-like symptoms and treatment was withdrawn. In June 1994 rHuEPO was resumed at a very low dose of 100 IU subcutaneously three times weekly, and was increased gradually to 500 IU, without inducing any side-effects. At this dose the haematocrit was maintained at 22.0 - 25.0% and the symptoms of anaemia improved. In patients like ours, with influenza-like symptoms caused by rHuEPO therapy, dose escalation starting from an ultra-low dose may be effective in avoiding side-effects.
