小儿营养性缺铁性贫血合并反复感染免疫状态研究

RESEARCH OF IMMUNOLOGICAL STATE OF CHILDREN WITHIRON DIFICIENCY ANEMIA COMPLICATING RECURRENT IN-FECTION

对２２名营养性缺铁性贫血合并反复感染儿童进行了Ｔ细胞亚群、中性粒细胞吞噬功能和血清免疫球蛋白测定，结果显示，本组患儿Ｔ细胞亚群中ＣＤ＿３、ＣＤ＿４数量及ＣＤ＿４／ＣＤ＿８比值、中性粒细胞吞噬功能均明显低于对照组，而血清中ＩｇＧ、ＩｇＡ、ＩｇＭ含量与正常同龄儿童对比无显著性差异．显示细胞免疫功能明显受损．提示防治缺铁性贫血，调节细胞免疫功能，增强中性粒细胞吞噬功能，对防治儿童反复总染，提高身体素质，是非常重要的。

Immune state of 22 children with IDA complicating RI had been studied. Result showed:the phagocytosis of neutrophil and count of CD_3,CD_4 ,CD_4/CD_8 in the terminal blood was lowerin the sick group than in the control.But content of IgG,IgA,IgM in the serum between sickand control group has no evident distinguish. Showed that cellular immune function was im-paired obviously.Point out:it is very important to prevent and treat IDA,in order to decrease in-cidence of the RI in the children.
