Abstract

We treated an infant with anemia and chronic renal failure with recombinant human erythropoietin (300 to 750 U/kg subcutaneously per week) and iron (6 mg/kg enterally) from 1 to 4 months of age. A suboptimal pharmacodynamic response was seen at the lower dose. This may have been due to developmental erythropoietin pharmacokinetic differences, that is, relatively greater neonatal plasma clearance and steady-state volume of distribution compared with those in adults.
