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 investigate the relationship between children’s recurrent respiratory tract infection and blood trace elements. Methods Sixty - four children with RRI and 64 healthy children (control group) were enrolled in this study. 60μl of peripheral blood and 6 elements of iron, zinc, calcium, copper, magnesium and lead were tested simultaneously. Results The levels of iron, zinc, calcium, copper and magnesium in the RRI group were significantly different from those in the control group (P <0.05). The levels of iron, zinc, calcium and copper in the RRI group were significantly different from those in the control group Lead levels were significantly higher than the control group, the difference between the two groups was statistically significant (P <0.05). Conclusions Children with recurrent respiratory tract infection and blood trace elements have a certain relevance, in the treatment of recurrent respiratory tract infections in children should pay attention to the supplementation of trace elements and the prevention and treatment of excessive lead.
