Input: No new trials were identified in March of 2012. Two high quality randomised double-blind controlled studies enrolling 262 infants were identified. A non-significant reduction in the 'Use of one or more RBC transfusions' [two studies 262 infants; typical RR 0.91 (95% CI 0.78 to 1.06); typical RD -0.07 (95% CI -0.18 to 0.04; I2 = 0% for both RR and RD] favouring early EPO was noted. Early EPO administration resulted in a non-significant reduction in the "number of transfusions per infant" compared with late EPO [typical MD - 0.32 (95% CI -0.92 to 0.29)]. There was no significant reduction in total volume of blood transfused per infant or in the number of donors to whom the infant was exposed. Early EPO led to a significant increase in the risk of retinopathy of prematurity (ROP) (all stages) [two studies, 191 infants; typical RR 1.40 (95% CI 1.05 to 1.86); typical RD 0.16 (95% CI 0.03 to 0.29); NNTH 6 (95% CI 3 to 33)]. There was high heterogeneity for this outcome (I2 = 86% for RR and 81% for RD). Both studies (191 infants) reported on ROP stage > 3. No statistically significant increase in risk was noted [typical RR 1.56 (95% CI 0.71 to 3.41); typical RD 0.05 (-0.04 to 0.14)] There was no heterogeneity for this outcome (0% for both RR and RD). No other important favourable or adverse neonatal outcomes or side effects were reported. The use of early EPO did not significantly reduce the 'Use of one or more RBC transfusions' or the 'Number of transfusions per infant" compared with late EPO administration. The finding of a statistically significant increased risk of ROP (any grade) and a similar trend for ROP stage > 3 with early EPO treatment is of great concern.
Output:

A total of 262 infants born preterm have been enrolled in two studies of early versus late administration of EPO to prevent blood transfusions. There were no demonstrable benefits of early versus late administration of EPO with regards to reduction in the use of red blood cell transfusions, number of transfusions, the amount of red cells transfused or number of donor exposures per infant. However, the use of early EPO compared with late EPO administration increases the risk of retinopathy of prematurity, a serious complication in babies born before term. Currently, there is a lack of evidence that either treatment confers any substantial benefits with regard to any donor blood exposure, as many infants enrolled in both studies were exposed to donor blood prior to study entry, and early EPO increases the risk of retinopathy of prematurity. Neither early nor late administration of EPO is recommended.
