OBJECTIVES: Using the approach of a meta-analysis, we sought to determine whether the administration of recombinant erythropoietin (rEpo) to very low birth weight (VLBW) infants, after the first week of life, results in fewer "late" transfusions. STUDY DESIGN AND METHODS: The guidelines set forth by the Cochrane Neonatal Review Group were used to identify all relevant studies. Medline was searched from January 1990 to November of 2000. Studies that used a randomized, placebo-controlled, and double-masked design were deemed acceptable. RESULTS: Eight studies meet the inclusion criteria. These involved 357 VLBW neonates: 183 rEpo and 174 placebo recipients. The neonates in the rEpo group received fewer erythrocyte transfusions during the study period than did those in the placebo group; the common odds ratio (OR)=0.33; 95% confidence interval (CI) 0.21-0.51. Furthermore, the rEpo effect size was a function of the dose of rEpo administered (p=0.0001). CONCLUSION: A meta-analysis of the most scientifically rigorous studies on this topic indicates that administration of rEpo to VLBW infants reduces "late" erythrocyte transfusions in a dose-dependent manner.
