The aims of this study were to evaluate the response of oral iron treatment in children with iron deficiency anemia (IDA) fed whole cow's milk (WCM) or soy formula; to compare the incidence of fecal blood loss in infants fed WCM and soy formula; and to evaluate the incidence and relation of protein-losing enteropathy (PLE) and IDA by testing serum albumin, fecal blood loss, and fecal alpha1-antitrypsin (alpha1AT).
Twenty-four children with nutritional IDA were randomly assigned to receive either 16 oz WCM or soy formula daily. Both groups were treated with daily therapeutic oral iron during 12 weeks. Stool specimens for hemoglobin losses were collected at weeks 0, 3, 6, and 12. Levels of serum albumin and fecal alpha1AT were tested at diagnosis and when IDA was corrected.
Anemia was corrected in 21 of the 24 children by week 6 or 12. Median fecal hemoglobin losses were not increased in either group at diagnosis or during treatment. Seven of 24 children had PLE at diagnosis with elevated fecal alpha1AT levels of 72 to 381 mg/dL that returned to normal after correction of IDA. Their initial fecal alpha1AT levels averaged 170 mg/ dL at diagnosis and 21 mg/dL after the IDA was corrected. Excessive WCM intake of 30 oz/day or more was present in 63% of the infants.
Treatment of nutritional IDA with oral iron was just as effective with a limited quantity of either WCM or soy formula. Fecal hemoglobin losses were uncommon and did not differ in children at diagnosis or during treatment of IDA. PLE associated with IDA resolves when the IDA is corrected, but differences between children fed WCM or soy formula could not be detected.
本研究旨在评估缺铁性贫血(IDA)患儿食用全脂牛奶(WCM)或大豆配方奶粉时口服铁剂治疗的反应;比较食用WCM和大豆配方奶粉的婴儿粪便失血的发生率;并通过检测血清白蛋白、粪便失血和粪便α1-抗胰蛋白酶(α1AT)来评估蛋白丢失性肠病(PLE)与IDA的发生率及关系。
24例营养性IDA患儿被随机分配,每天分别接受16盎司WCM或大豆配方奶粉。两组均在12周内每日接受口服治疗性铁剂。在第0、3、6和12周收集粪便标本以检测血红蛋白丢失情况。在诊断时及IDA得到纠正时检测血清白蛋白和粪便α1AT水平。
到第6周或12周时,24例患儿中有21例贫血得到纠正。两组在诊断时或治疗期间粪便血红蛋白丢失的中位数均未增加。24例患儿中有7例在诊断时有PLE,粪便α1AT水平升高至72至381mg/dL,IDA纠正后恢复正常。他们诊断时粪便α1AT的初始水平平均为170mg/dL,IDA纠正后为21mg/dL。63%的婴儿存在每日摄入30盎司或更多WCM的情况。
用口服铁剂治疗营养性IDA时,无论食用有限量的WCM还是大豆配方奶粉,效果都一样。粪便血红蛋白丢失不常见,且在IDA诊断时或治疗期间患儿中无差异。与IDA相关的PLE在IDA纠正后可缓解,但未检测到食用WCM或大豆配方奶粉的患儿之间存在差异。
