Excess of iron and oxidant injury shortly after birth may be associated with neonatal morbidities in preterm infants.
The aim was to determine whether administration of erythropoietin without iron supplementation decreases iron load and morbidity.
In a randomized trial, we administered erythropoietin (EPO 250IU/kg daily during the first 6days of life) or placebo to 39 preterm infants (BW 700-1500g, GA≤30.0weeks).
The iron status, postnatal morbidities and follow-up at the age of two years were investigated.
In all, 21 EPO- and 18 placebo-treated infants were recruited. A requirement of red blood cell transfusions during first 28days was similar between the study groups. EPO treatment decreased total serum iron concentration (p=0.035). EPO supplementation had no significant effect on serum transferrin receptors or reactive non-protein-bound iron. There were no differences in neonatal morbidity or in survival without major neurological abnormality at two years of age.
A 6-day course of EPO decreased the iron load in preterm infants. There was no change in reactive, non-protein bound iron plasma levels and no influence on the outcomes during early childhood. Whether the neurocognitive effects of early EPO treatment can be detectable later in childhood remained to be verified.
出生后不久铁过量和氧化损伤可能与早产儿的新生儿疾病有关。
目的是确定不补充铁剂给予促红细胞生成素是否能降低铁负荷和发病率。
在一项随机试验中,我们对39名早产儿(出生体重700 - 1500克,胎龄≤30.0周)给予促红细胞生成素(出生后前6天每天250IU/kg)或安慰剂。
调查铁状态、出生后发病率及两岁时的随访情况。
总共招募了21名接受促红细胞生成素治疗和18名接受安慰剂治疗的婴儿。研究组在出生后前28天内对红细胞输血的需求相似。促红细胞生成素治疗降低了总血清铁浓度(p = 0.035)。补充促红细胞生成素对血清转铁蛋白受体或反应性非蛋白结合铁没有显著影响。新生儿发病率或两岁时无重大神经异常的存活率没有差异。
6天疗程的促红细胞生成素降低了早产儿的铁负荷。反应性非蛋白结合铁血浆水平没有变化,对幼儿期的结局也没有影响。早期促红细胞生成素治疗对神经认知的影响在儿童后期是否可检测到仍有待验证。
