AJG:补充乳铁蛋白和溶菌酶可改善环境肠道功能障碍

2019-05-20 不详 MedSci原创

环境肠道功能障碍(EED)会使儿童易暴露于肠道病原体中,而且会导致发育迟缓。治疗或预防EED在儿童期具有重要意义。因此,本研究旨在评估添加母乳中的2种成分是否会改善EED的生物标志物。

背景及目的:
环境肠道功能障碍(EED)会使儿童易暴露于肠道病原体中,而且会导致发育迟缓。治疗或预防EED在儿童期具有重要意义。因此,本研究旨在评估添加母乳中的2种成分是否会改善EED的生物标志物。

方法:
研究人员进行了一项针对12-23个月儿童的前瞻性,随机,双盲,安慰剂对照临床试验。实验组每日补充1.5克乳铁蛋白和0.2克溶菌酶,持续16周。主要观察结果是EED的改善情况,其评价方法主要通过尿液中摄入的乳果糖百分比的变化来衡量(Δ%L)。

结果:
在完成研究的214名儿童中,对照组和实验组在8周内Δ%L存在显着差异(0.23% VS 0.14%; P = 0.04)。然而,这项相对改善并未在16周内持续强劲增长(0.16% VS 0.11%; P = 0.17)。实验干预组在研究过程中住院率和急性营养不良的发生率显着降低(2.5% VS 10.3%,相对风险0.25; P <0.02)。

结论:
在出生第二年的儿童群体中补充乳铁蛋白和溶菌酶对肠道健康有益。这种干预措施还可以防止住院治疗和急性营养不良的发生。
