背景对早产儿使用促红细胞生成素 (EPO) 的临床试验并未重点关注体重 750 克或以下的婴儿,而该人群由于大量静脉切开术损失而最有可能接受多次输血。目前尚不清楚体重 750 克或以下的早产儿是否会通过加速红细胞生成对 EPO 产生反应,或者向该人群施用 EPO 是否会减少输血。方法我们随机分配 28 名极低出生体重早产儿(平均值±SEM:妊娠 24.7 ± 0.3 周,出生体重 662 ± 14 克)在生命的前 72 小时内接受 EPO(200 U/kg/天)或安慰剂 14 天,并在 21 天的研究期内仅根据方案进行输血。在 14 天的治疗期间,所有婴儿均在总肠外营养液中接受 1 mg/kg/天的右旋糖酐铁。 结果在 21 天的研究期间,EPO 接受者接受的输血次数和体积(每名患者 4.7 ± 0.7 次输血,每名患者 70 ± 11 ml/kg)低于安慰剂接受者(每名患者 7.5 ± 1.1 次输血,112 次输血)。每名患者 ± 17 ml/kg;p < 0.05,EPO 与安慰剂相比),而两组的血细胞比容保持相似。第 1 天两组的网织红细胞计数相似,但第 14 天 EPO 接受者的网织红细胞计数更高(EPO 第 1 天,351 ± 53;EPO 第 14 天,359 ± 40 × 103/μl;安慰剂第 1 天,334 ± 64;安慰剂第 14 天,120 ± 10 × 103/μl;p < 0.01, EPO 与安慰剂)。在研究开始时,两组的血清铁蛋白浓度相似,但在第 14 天时安慰剂组的血清铁蛋白浓度更高(EPO,262 ± 44 μg/L;安慰剂,593 ± 92 μg/L;p < 0.01)。未发现 EPO 或铁剂的副作用。 结论 EPO 与肠外铁剂的组合可刺激体重 750 克或以下的早产儿的红细胞生成,并导致出生后前 3 周内的输血次数减少。 (儿科杂志 1997;131:661-5)
BackgroundClinical trials of erythropoietin (EPO) administration to preterm infants have not focused on infants weighing 750 gm or less, the population most likely to receive multiple transfusions because of large phlebotomy losses. It is unknown whether preterm infants weighing 750 gm or less will respond to EPO by accelerating erythropoiesis, or whether EPO administered to this population will decrease blood transfusions.MethodsWe randomly assigned 28 extremely low birth weight preterm infants (mean ± SEM: 24.7 ± 0.3 weeks’ gestation, 662 ± 14 gm birth weight), in the first 72 hours of life, to receive either EPO (200 U/kg/day) or placebo for 14 days and administered transfusions only according to protocol over a 21-day study period. All infants received 1 mg/kg/day iron dextran in their total parenteral nutrition solution during the 14-day treatment period.ResultsDuring the 21-day study period, a lower number and volume of transfusions were received by the EPO recipients (4.7 ± 0.7 transfusions per patient and 70 ± 11 ml/kg per patient) than by the placebo recipients (7.5 ± 1.1 transfusions per patient and 112 ± 17 ml/kg per patient; p < 0.05, EPO vs placebo), whereas hematocrits remained similar in the two groups. Reticulocyte counts were similar in both groups on day 1 but were greater in the EPO recipients on day 14 (EPO day 1, 351 ± 53; EPO day 14, 359 ± 40 × 103/μl; placebo day 1, 334 ± 64; placebo day 14, 120 ± 10 × 103/μl; p < 0.01, EPO vs placebo). Serum ferritin concentrations were similar in both groups at the beginning of the study but were greater in the placebo recipients by day 14 (EPO, 262 ± 44 μg/L; placebo, 593 ± 92 μg/L; p < 0.01). No adverse effects of EPO or iron were noted.ConclusionThe combination of EPO and parenteral iron stimulates erythropoiesis in preterm infants weighing 750 gm or less and results in fewer transfusions during their first 3 weeks of life.
