摘要: 目的:揭示儿童EB病毒(Epstein-Barr virus, EBV)感染后肝功能变化和细胞免疫状态的关系,为儿童EBV感染临床诊疗提供依据。方法:回顾性收集2017年4月1日至9月30日首都儿科研究所附属儿童医院住院确诊为EBV感染病例的临床和实验室检测资料,对EBV感染肝功能异常组和肝功能正常组患儿的性别、年龄、确诊疾病种类以及T细胞、辅助/诱导T细胞、调节/抑制T细胞、CD4+/CD8+比值、B细胞、自然杀伤(natural killer,NK)细胞、总淋巴细胞指标进行统计学分析。结果:共75例EBV感染住院儿童,发生肝功能异常者34例,未发生肝功能异常组41例;肝功能异常组和肝功能正常组患儿性别比例(χ2=0.077,P=0.783)、年龄均值(t=1.042,P=0.301)差异均无统计学意义;T细胞(t=1.943,P=0.058)、B细胞(t=1.741,P=0.088)、NK细胞(t=0.523,P=0.603)、总淋巴细胞(t=0.915,P=0.365)指标差异均无统计学意义;辅助/诱导T细胞(t=5.161,P=0.000)、调节/抑制T细胞(t=5.446,P=0.000)、CD4+/ CD8+比值(t=4.031,P=0.000)指标差异均有统计学意义。结论:调节性细胞免疫功能紊乱可能是儿童EBV感染肝功能异常的原因之一。

Abstract: Objective:To disclose the relationship between the changes of liver function and cellular immunological state of children with Epstein-Barr virus(EBV) infection, which provides the basis for clinical diagnosis and treatment of EBV infection of children. Methods:The clinical and laboratory test data of hospitalized children diagnosed with EBV infection from April 1 to September 30, 2017 in Children′s Hospital Affiliated to the Capital Institute of Pediatrics were retrospectively collected The indexes of gender, age, disease type, T cells, helper/induction T cells, regulation/suppression T cells, CD4+/CD8+ ratio, B cells, natural killer(NK) cells and total lymphocytes in normal and abnormal liver function group were statistically analyzed. Results:34 cases occurred liver dysfunction in 75 cases of hospitalized children with EBV infection, and 41 cases didn′t occurre liver dysfunction. The differences of the gender proportion (χ2=0.077, P=0.783), mean age (t=1.042, P=0.301), T cells (t=1.943, P=0.058), B cells (t=1.741, P=0.088), NK cells (t=0.523, P=0.603), total lymphocytes (t=0.915, P=0.365) between the normal group and abnormal liver function group were all not statistically significant. However, the differences of helper/induction T cells (t=5.161, P=0.000), regulation/inhibition T cells (t= 5.446, P=0.000), CD4+/CD8+ ratio (t=4.031, P=0.000) between the normal group and abnormal liver function group were all statistically significant. Conclusion:The regulatory cellular immune dysfunction perhaps is one of the reasons caused the abnormal liver function of children with EBV infection.
