Objective:
To explore the relationship of Epstein-Barr virus (EBV) specific antibodies detection and the diagnoses of infectious mononucleosis (IM) caused by EBV.
Methods:
Single serum samples were collected from 220 inpatients with the diagnosis of IM between January 2005 and December 2006 in Beijing Children's hospital. The samples were detected for EBV-CA-IgM, EBV-CA-IgG, EBV-EA-IgG, EBV-NA-IgG and the avidity of EBV-CA-IgG by indirect immunofluorescent assay.
Results:
The positive rate of EBV-CA-IgG, EBV-CA-IgM, EBV-EA-IgG and EBV-NA-IgG were 100%, 95.9%, 79.5% and 4.1% respectively. Low-avidity EBV-CA-IgG was detected in 204 patients (92.7%) with positive EBV-CA-IgM and EBV-CA-IgG,negative EBV-NA-IgG, low-avidity EBV-CA-IgG were the main pattern of EBV antibody in IM patients (84.6%).
Conclusion:
The existence of EBV specific antibody (CA-IgG, CA-IgM, EA-IgG, NA-IgG and avidity of CA-IgG) could add more information to identify the stage of EBV infection so as to provide more reliable serological evidence for the diagnosis of IM.
