To evaluate the efficacy and safety of recombinant human erythropoietin (rHuEPO) in very low birth weight infants with anemia of prematurity.
Thirty infants were randomly assigned to receive either rHuEPO (300 U/kg per dose) or placebo twice a week. Hematologic parameters, transfusion requirements, caloric intake, and growth were monitored.
The number and volume of erythrocyte transfusions were significantly lower in infants treated with rHuEPO. Serum ferritin levels, similar in both groups at study entry, fell and were significantly lower in rHuEPO-group infants at the completion of the study. An inverse correlation was observed between reticulocyte count and absolute neutrophil count both at entry and at completion of the study.
Twice-a-week administration of rHuEPO significantly reduces the need for erythrocyte transfusion in very low birth weight infants in stable condition. A significant decrease in serum ferritin levels in infants receiving rHuEPO suggests the need to determine the optimal dose of iron supplementation in these infants.
评估重组人促红细胞生成素(rHuEPO)用于极低出生体重早产儿治疗贫血的疗效和安全性。
30例婴儿被随机分为两组,一组接受rHuEPO(每剂300 U/kg),另一组接受安慰剂,均每周给药两次。监测血液学参数、输血需求、热量摄入和生长情况。
接受rHuEPO治疗的婴儿红细胞输血的次数和量显著更低。两组在研究开始时血清铁蛋白水平相似,但在研究结束时,rHuEPO组婴儿的血清铁蛋白水平下降且显著低于另一组。在研究开始和结束时,网织红细胞计数与绝对中性粒细胞计数之间均呈负相关。
每周两次给予rHuEPO可显著降低病情稳定的极低出生体重婴儿的红细胞输血需求。接受rHuEPO治疗的婴儿血清铁蛋白水平显著下降,提示需要确定这些婴儿补铁的最佳剂量。
