ABSTRACT

PURPOSE:

We conducted randomized study to determine whether high doses (6mg/kg/ day) of iron would exert a more supplemental effect than low doses (3mg/kg/day), and which regimen of recombinant human erythropoietin (rHuEPO) and iron would be more beneficial in the prophylactic treatment of anemia of prematurity.

METHODS:

We randomly assigned 38 sick premature infants who were more likely than symptom-free premature infants requiring erythrocyte transfusions for infants with anemia of prematurity to receive rHuEPO, 100unit/kg, tiw, subcutaneously, plus iron, 3mg/kg/day, po, daily from the second day of life (group 1), 100unit/kg and 6mg/kg/ day (group 2), 200unit/kg and 3mg/kg/day (group 3), and 200unit/kg and 6mg/kg/day (group 4), respectively.

RESULTS:

There were no significant differences of hemoglobin levels and iron balances during treatment among all 4 groups. The rates of increase in reticulocyte counts were greater in group 4 and group 2 compared with group 3 and group 1, respectively, though these rates were statistically not significant. The blood volume differences (volume of phlebotomies-volume of transfusions) during treatment were higher in group 4 compared with group 1 (p<0.05).

CONCLUSIONS:

High doses of iron may be more effective in rapidly increasing reticulocyte counts, and 200unit/kg, tiw of rHuEPO plus 6mg/kg/day of iron is more beneficial in reducing the need for blood transfusions than any other regimen. Therefore the prophylactic treatment of anemia of prematurity and acute blood loss from frequent blood sampling in risky premature infants with rHuEPO, 200unit/kg, tiw, subcutaneously, plus iron 6mg/kg/day, po, daily from the second day of life is effective in reducing the number of blood transfusions. Additional controlled trials utilizing high doses of iron with rHuEPO and larger numbers of patients are justified.
