轮状病毒肠炎患儿血清和大便IL-2,IL-6,IFN-γ动态变化及与临床指标关系的研究

目的　研究轮状病毒肠炎患儿血清和大便IL 2、IL 6、IFN γ的动态变化 ,及临床指标的关系。方法　采用双抗体夹心ELISA法。结果　 119例腹泻患儿RV阳性率 6 3.0 % ,当年 11月份为高峰月。这些细胞因子在病程中呈不同的高峰时相 ,大便IFN γ达峰值最早 ,血清及大便IL 2达峰值最晚 ,大便IL 2与IL 6差异有非常显著性 (P <0 .0 1) ,大便IL 2与IFN γ、IL 6与IFN γ、血清IL 2与IL 6、腹泻恢复时间与大便IL 2、血、便IL 2及IFN γ与淋巴细胞 +单核细胞均差异有非常显著性或差异有显著性 (P <0 .0 1或P <0 .0 5 )。结论　IL 2、IL 6、IFN γ在婴幼儿轮状病毒肠炎中发挥了重要的免疫调控作用 ,且与临床指标密切相关。

Dynamic variation of serum and stool level of interleukin-2,interleukin-6 and interferon-γ in children with rotavirus enteritis and its relation to clinical manifestations

OBJECTIVE: This study was conducted to observe dynamically the serum and stool level of IL-2, IL-6 and IFN-alpha with RV enteritis, and to analyse the relation of them and their relation to clinical manifestations. METHODS: The double-antibody sandwich ELISA technique was applied. RESULTS: The positive rate of RV in 119 enteritis cases was 63.0% and the peak month was November. These cytokines had different peak phases in the course of disease. The earliest cytokine which had peak phase was IFN-alpha, the last ones were serum and stool IL-2. There was a negative relation between stool IL-2 and IL-6 (P<0.01). There were positive relation between IL-2 and IFN-alpha, stool IL-6 and IFN-alpha, serum IL-2 and IL-6, stool IL-2 and the recovery time of the enteritis (P<0.01 or P<0.05). Serum and stool level of IL-2 and IFN-alpha had positive relation to the number of lymphocyte plus mononuclear cells (P<0.01 or P<0.05). CONCLUSIONS: IL-2, IL-6 and IFN-alpha play important roles of immunoregulation in RV enteritis, and have close relation to clinical manifestations.
