ABSTRACT
Objective To study the characteristics of immune function,Epstein-Barr virus(EBV) antibodies and EBV-DNA in children with different clinical types of EBV infection,which provide basis for prevention and treatment of EBV infection.Methods Clinical data of 103 patients suffering from EBV infection were retrospectively analyzed in Xijing Hospital of the Fourth Military Medical University.A total of 103 children were divided into infectious mononualeosis(IM) group(n=68),chronic active Epstein-Barr virus infection(CAEBV) group(n=13) and Epstein-Barr virus-related hemophagocytic lymphohistiocytosis(EBV-HLH) group(n=22).The changes of EBV antibodies,EBV-DNA,immunoglobulin levels,lymphocyte subpopulation and complement series were detected and compared among the three groups.A total of 26 healthy children at the same stage were enrolled as a control group,immunoglobulin levels,lymphocyte subpopulation and complement series were detected in control group,then compared with the rest of the three groups.Results The levels of C3 and C4 in CAEBV group and EBV-HLH group were significantly decreased than those in the control group(P0.05).CD8+T cells in IM group significantly increased than those in the rest of the three groups(P<0.05,respectively).T cells,CD8+T cells,CD4+ T cells,CD4+/CD8+ ratios,NK cells,B cells of EBV-HLH group significantly decreased than those in the rest of the three groups(P<0.05).The positive rates of EBV antibodies in CAEBV group and IM group were significantly higher than those in EBV-HLH group(P<0.05).EBV-DNA in EBV-HLH group were significantly higher than those of CAEBV group and IM group(P<0.05).Conclusion EBV-DNA levels in the serum are positively correlated with disease types and severity,the pathogenesis of IM,CAEBV and EBV-HLH induced by EBV infection are associated with immune dysfunction.Dynamic monitoring of EBV load and cell immune function can reflect disease status and progress risk.
