title: Altered prevalence and reactivity of anti-Epstein-Barr virus antibodies in patients with multiple sclerosis.
abstract: In this study, the prevalence and reactivity of anti-Epstein-Barr virus (EBV) antibodies were investigated in 107 patients with multiple sclerosis (MS) in comparison to age- and gender-matched healthy controls from a north German state. We found a significant 100% EBV-seropositivity and a significant lack of primary EBV infections in the MS group, indicating that all MS patients are infected with EBV before the development of MS. Although there were no differences in reactivities of EBV-specific anti-early antigen (EA)-immunoglobulin G (IgG), -IgM, and -IgA antibodies between each group, MS patients had significant lower anti-Epstein-Barr nuclear antigen (EBNA)1-IgG antibody titers as a possible serological sign for a defective control of the persistent latent EBV carrier state and EBV reactivations. Longitudinal studies of MS patients are necessary to further determine the implications of EBV reactivations on the course and disease activity of MS.
