  • Title: Correlations between Epstein-Barr virus antibody levels and risk factors for multiple sclerosis in healthy individuals.
    Author: Nielsen TR, Pedersen M, Rostgaard K, Frisch M, Hjalgrim H.
    Journal: Mult Scler; 2007 Apr; 13(3):420-3. PubMed ID: 17439912.
    Abstract:
    BACKGROUND: Female gender, human leukocyte antigen (HLA) DR2, tobacco smoking and Epstein-Barr virus (EBV) are established risk factors for multiple sclerosis (MS). Their possible interaction however, has been sparsely studied. OBJECTIVES: To investigate possible associations between EBV antibody levels and a range of other recognized MS risk factors. DESIGN, SETTING AND STUDY POPULATION: Cross-sectional study undertaken in Denmark based on 517 healthy individuals selected from the Danish population. METHODS: We measured change in mean log (anti-Epstein-Barr viral capsid antigen (VCA) immune globulin G) using linear regression. RESULTS: Anti-Epstein-Barr VCA immune globulin G levels were positively correlated with female gender and HLA DR2. Furthermore, current smoking and cumulative tobacco consumption were positively associated with EBV antibody levels. CONCLUSION: The association between Epstein-Barr VCA antibody levels and non-viral MS risk factors support the view that EBV is critically involved in the etiology of MS. These non-viral MS risk factors may be linked with MS risk through EBV-specific immune responses.
