血微量元素水平与小儿反复呼吸道感染相关性研究

Study of relationship between trace elements in blood and recurrent respiratory infection in children

目的探讨小儿反复呼吸道感染与血微量元素的关系。方法选择64例反复呼吸道感染患儿(RRI组)与64例健康儿童(对照组)作为研究对象,取末梢血60μl,同时检测铁、锌、钙、铜、镁、铅等6种元素。结果 RRI组血中铁、锌、钙、铜、镁水平较对照组存在不同程度缺乏,其中铁、锌、钙、铜与对照组比较差异有统计学意义著(P<0.05),而RRI组血铅水平明显高于对照组,两组比较差异有统计学意义(P<0.05)。结论小儿反复呼吸道感染与血中微量元素有一定相关性,在治疗小儿反复呼吸道感染的同时应重视微量元素的补充及铅过量的防治。

Objective To explore the relationship between recurrent respiratory infection in children and trace elements in their blood.Methods Sixty-four children with recurrent respiratory infection（RRI group）and 64 healthy children（control group）were enrolled into the study,and their trace elements were tested.Results RRI group was short of Zn,Fe,Ca,Cu and Mg in the blood in different degrees,and the differences in the trace elements were significant when compared with control group（P〈0.05）.However,the lead level of RRI group exceed that of control group significantly（P〈0.05）.Conclusion There exists a relationship between trace elements in blood and recurrent respiratory infection in children,so we should pay more attention to the replenishment of trace elements and to the prevention and the cure of excessive lead when we treat the children with recurrent respiratory infection.
