Abstract:
Objective To analyse effects of zinc on immune function in children with infantile pneumonia .Methods A total of 96 children with infantile pneumonia selected from May to July 2014 were randomly divided into zinc supplementary treatment group and routine treatment group ,with 48 cases in each group .Routine treatment group was given conventional treatment ,while the zinc supplementary treatment group was received conventional treatment combined with zinc supplement .The serum level of zinc and immune function were detected before and after treatment ,respectively .Other 40 healthy infants received physical examination were contemporarily selected as healthy control group .Results Before treatment ,the levels of serum zinc ,IgA ,IgM and IgG ,percentages of CD3+ ,CD4+ cells and the CD4+ /CD8+ ratio in the two groups of children with infantile pneumonia were lower than those in the healthy control group ,while percentage of CD8+ cells was lower than that in the healthy control group ,had statistically significant differences(P<0 .05) .While no statistically significant differences of indicators mentioned above were found between the zinc sup‐plementary treatment group and routine treatment group before treatment(P> 0 .05) .After treatment ,the levels of serum zinc , IgA ,IgM and IgG ,percentages of CD3+ ,CD4+ cells and the CD4+ /CD8+ ratio in the zinc supplementary treatment group were higher than those in the routine treatment group ,and percentage of CD8+ cells was lower than that in the routine treatment group , had statistically significant differences(P<0 .05);while compared with the healthy control group ,levels of serum zinc ,IgA ,IgM , IgG were still lower ,had statistically significant differences(P<0 .05) .After treatment ,levels of serum zinc ,IgA ,IgM ,IgG ,per‐centages of CD3+ ,CD4+ cells and the CD4+ /CD8+ ratio in the routine treatment group were still lower than those in the healthy control group ,and percentage of CD8+ cells was still higher than that in the healthy control group ,had statistically significant differences(P<0 .05) .Conclusion Zinc can effectively improve the immune function of children with infantile pneumonia ,which might shorten treatment time and reduce adverse outcomes .
