*EBV antibody was measured by using commercial kit Euroimmun (Medizinische Labordiagnostika, Lübeck, Germany). Results were evaluated semiquantitatively by calculating a ratio of the extinction value of the control or patient samples over the extinction value of calibrator. Ratio <0.8: negative; ratio >1.1: positive. EBV, Epstein-Barr virus; CSF, cerebrospinal fluid; VCA, viral capsid antigen; EBV NA, EBV nuclear antigen indicating past EBV infections; EBV EA, EBV early antigen, indicating current or recent EBV infection; –, negative; +, positive; ND, not done.
