Twenty-five premature infants (mean gestational age+/-SD, 31.4+/-1.9 weeks) were administered subcutaneously recombinant human erythropoietin (rHuEpo) at a dose of 300 u/kg of body weight three times a week beginning on the third day of life and continuing for 6 weeks. The controls (n=23) were premature infants with a mean gestational age of 32.2+/-2.3 weeks who did not receive rHuEpo. Haematological indices, haemoglobin and serum phosphate (Pi), and red blood cell (RBC) phosphate metabolites (ATP, 2,3-DPG, RBCPi) were tested monthly until the 6th month and thereafter at the 9th and 12th months of life. The level of serum soluble transferrin receptors (sTfR) correlated significantly with rHuEpo (p<0.05). The ratio of sTfR to log (ferritin) was significantly higher (p<0.001) in the infants treated with rHuEpo than the controls. Intracellular organic and inorganic Pi changes were not affected by the Epo administration. The RBC 2,3-DPG seemed adequate in infants receiving rHuEpo.
