补充铁锌对反复呼吸道感染患儿血清12种微量元素的影响

Influence of replenishing iron and/or zinc for 12 kinds of trace elements in serum in children with recurrent respiratory tract infections

检测84例反复呼吸道感染(RRTI)患儿血清Zn、Mn、Al、Cd、Fe、Pb、Cu、Ni、Ti、Co、Li、Cr水平,对其中血锌或(和)铁水平降低者37例进行了补充富马酸亚铁和(或)硫酸锌治疗后纵向观察。结果表明治疗前RRTI组血清Zn、Fe、Pb、Ni、Ti、Co、Li均值显著降低;治疗2个月后,RRTI随临床症状改善、血清Zn、Fe、Ti、Co、Li、Cr水平较前明显升高,而Al、Cd、Cu水平下降。提示RRTI患儿存在锌、铁等多种微量元素缺乏或不足,补充铁和(或)锌对其他微量元素的吸收、分布有明显影响。

The level of serum Zn. Mn. Al. Cd. Fe. Pb. Cu. Ni. Ti. Co. Li. Cr were measured in 84 cases children with recurrent respiratory tract infections (RRTI) and replenishment of iron and/or zinc had been done in 37 cases children with RRTI in company with low of serum Zn or/and Fe. Comparing with controls, mean of serum Zn. Fe. Pb. Ni. Co. Li were decerased in children with RRTI before treatment. After treatment two months, a increase of serum Zn. Fe. Ti. Co. Li. Cr. and decrease of serum Al. Cd.Cu and improvement of symptom were observed in RRTI children. The result would suggest that RRTI have many kinds of trace elements deficiency or insufficiency (including iron and zinc deficiency) and replenishing iron and/or zinc can effect absorption and separation of other trace elements in children with RRTI.
