微量元素锌与儿童反复呼吸道感染

The Relationship Between Trace Element Zinc and Children with Recurrent Respiratory Tract Infection(RRTI)

目的探讨儿童反复呼吸道感染与血清微量元素锌的关系。方法将32例反复呼吸道感染患儿(设为感染组),30例健康儿(设为对照组)进行血微量元素检测,并对感染组患儿进行口服锌治疗三个月后进行血微量元素锌检测,将结果进行分析。结果感染组血锌(42.52±4.02)umol/L,对照组血锌(79±7.28)umol/L,感染组血锌明显低于对照组(p<0.01)具有显著意义。感染组治疗前血锌(42.52±4.02)umol/L,经口服锌治疗三月后血锌(71.76±6.47)umol/L,感染组治疗前血锌低于治疗后血锌(p<0.01)具有显著意义。结论血中微量元素锌缺乏可出现反复呼吸道感染,对其进行口服锌治疗呼吸道感染次数减少。

Objective To investigate the relationship between trace element zinc and children with recurrent respiratory tract infection （RRTI）. Methods We tested the content of zinc in the serum in 32 cases of children with RRTI and 30 cases healthy children ,and 32 cases of the patients were treated with zinc orally. Results In RRTI group ,the count of znic was obvious lower than that in the herhhy children group （p〈0.01）, they have significant difference. The patients were treated with zinc orally . Zinc in the serum changes before and after medical treatment were observed,average values were （42.52±4.02）umol/L and （71.76±6.47）umol/L （p〈0.01） , they have significant difference. Conclusion Lack of zinc is one of the factors children with RRTI, The number of times of the respiratory tract infection is reduced after carrying on the oral zinc treatment.
