Premature neonates are at risk for severe anemia and erythropoietin is the most important hormone in erythropoiesis. The aim of this study was to evaluate the influence of oral recombinant human erythropoietin (rhEPO) in proving erythropoiesis in neonates.
This was a randomized clinical trial study. Thirty neonates were enrolled from September 2007 to September 2008. The first group received oral rhEPO and Fe and the second, subcutaneous rhEPO and Fe. The patients' Hb, HCT and the need to blood transfusion were recorded. We included all infants with gestational age <34 weeks, birth weight <1500 gr, without respiratory distress (O2 Saturation> 85%, FiO2 of 30%), full feeding tolerance so that oral Fe can be administrated.
In first group (oral=PO), 65% of neonates were female and 35% were male, mean weight was 1140 g and mean GA was 32.6 weeks. In the second group (subcutaneous=SC), 42% were female and 58% were male. The mean weight was 1245 g and mean GA was 31.2 weeks and this was not statistically significant. In the first group, the mean Hb and HCT were 9.7±1.9 and 29.6±5.9 g/dl. In the second group, the figures were 12.5±1.7 and 38.8±5.1 which were statistically significant. There was no difference in the weight gain between two groups. In the first group, 3 neonates (20%) and in the second one, 1 neonate (15%) needed blood transfusion.
rhEPO administration either PO or SC could prevent anemia of prematurity but SC rout was more effective.
早产新生儿有发生严重贫血的风险,而促红细胞生成素是红细胞生成中最重要的激素。本研究的目的是评估口服重组人促红细胞生成素(rhEPO)对新生儿红细胞生成的影响。
这是一项随机临床试验研究。2007年9月至2008年9月招募了30名新生儿。第一组接受口服rhEPO和铁剂,第二组接受皮下注射rhEPO和铁剂。记录患者的血红蛋白(Hb)、血细胞比容(HCT)以及输血需求。我们纳入了所有胎龄<34周、出生体重<1500克、无呼吸窘迫(氧饱和度>85%,吸入氧分数为30%)、完全耐受喂养以便能口服铁剂的婴儿。
第一组(口服=PO)中,65%的新生儿为女性,35%为男性,平均体重为1140克,平均胎龄为32.6周。第二组(皮下注射=SC)中,42%为女性,58%为男性。平均体重为1245克,平均胎龄为31.2周,差异无统计学意义。第一组的平均Hb和HCT分别为9.7±1.9和29.6±5.9克/分升。第二组的相应数值分别为12.5±1.7和38.8±5.1,差异有统计学意义。两组之间体重增加无差异。第一组有3名新生儿(20%)需要输血,第二组有1名新生儿(15%)需要输血。
口服或皮下注射rhEPO均可预防早产儿贫血,但皮下注射途径更有效。
