ABSTRACT
Objective To investigate the early diagnostic value of EBV-DNA load in Plasma and peripheral blood mononuclear cells (PBMCs) for Children′s Primary Infectious Mononucleosis(IM).Methods The plasma and PBMCs samples were collected from children of 67 cases with primary IM (IM groups) and 75 healthy cases (H groups) during April, 2015 to March, 2016 in our hospital. The EBV-DNA load in PBMCs and plasma samples were quantified by Real-time PCR. Statistical differences between two groups were analyzed by using Mann-Whitney Test. Receiver operating characteristic curves (ROC) were analyzed to assess the early diagnostic value of EBV-DNA load for primary IM.Results Levels of EBV-DNA in the samples of plasma were significantly higher in the IM groups (median, 380 IU/ml) compared to the H groups (Z=-9.332,P<0.01), and levels of EBV-DNA in the PBMCs samples were also significantly higher (median, 2.51×105 IU/ml, Z=-9.194,P<0.01). According to ROC curve analysis, the AUC of EBV-DNA load in plasma was 0.908, the most appropriate cut-off value was 12.5 IU/ml (sensitivity 83.6% and specificity 94.7%),the AUC of EBV-DNA load in PBMCs was 0.944, the most appropriate cut-off value was 2.19×104 IU/ml (sensitivity 89.6% and specificity 82.7%), the AUC of combined testing(plasma and PBMCs) was 0.967(sensitivity 98.3% and specificity 99.0%).Conclusions Combined testing of plasma and PBMCs have better clinical value, it may be useful for the diagnosis of early stage of Children′s Primary Infectious Mononucleosis.
