Abstract:
Objective To investigate the clinical significance of Epstein-Barr virus EBV DNA in children with Epstein-Barr virus infection realated diseases.Methods A retrospective cohort study was performed.Totally 222 blood samples were collected from children who were diagnosed as EBV infection in Shandong Provincial Hospital from June 2012 to August 2013.Fluorescent quantitative PCR( FQ-PCR) was used to analyze the EBV DNA in peripheral blood lymphocytes.ELISA was used to analyze the four EBV serology antibodies in the serum.Two groups of tested results were compared.Heart, hepatic impairment and renal function were analyzed through detecting AST, ALT, BUN, CREA, CK, CKMB.The results were grouped by EBV DNA copy number, and then non-parametric test together with correlation analysis was performed using SPSS21.0 analytics software.Results The positive rate of EBV-CA IgM and EBV DNA was 51.35%(114/222) and 72.97% (162/222) respectively, χ2 =24.01, P<0.001.The EBV DNA copy number was significant difference (χ2 =11.79,P<0.05) in children at different stages of infection ( no previous infection:6.30 ×103 -1.20 ×104 copies/ml;early infection:5.56 ×103 -3.92 ×106 copies/ml;acute infection:6.58 ×103 -1.73 ×106 copies /ml;chronic infection or recurrent infection:8.92 ×103 -2.34 ×104 copies/ml;late infection or recovery:5.20 ×103 -1.12 ×107 copies/ml;past infection:5.46 × 103 -1.33 ×104 copies/ml).Each biochemical targets were divided into five groups by EBV DNA copy number (Ⅰ>1 ×106 copies/ml,Ⅱ1 ×105 -1 ×106 copies/ml, Ⅲ1 ×104 -1 ×105 copies/ml, Ⅳ5 × 103 -1 ×104 copies/ml, Ⅴ<5 ×103 copies/ml), and ALT(χ2 =10.14,P<0.05), BUN(χ2 =18.17, P<0.05), CK(χ2 =13.09,P<0.05), CKMB(χ2 =17.93,P<0.01) had a statistically significant difference between each group.Well, the log value of EBV DNA copy number had a positive correlation relationship with AST(r=0.357,P=0.001), ALT(r=0.376,P=0.001), BUN(r=0.329,P=0.000), CK(r=0.235,P=0.035).Conclusions Detection of EBV DNA can be used for the early diagnosis and assessment of process of the EBV infection related disease in children.The detection of liver, kidney function and myocardial enzymes can be used for evaluating the severity of EBV infection.
