    Abstract:
    Antibody reactivity to Epstein-Barr virus (EBV)-associated nuclear antigen (EBNA) was investigated by means of the anticomplement immunofluorescence technique on sera from patients with Hodgkin's disease (HD) and from appropriate controls. Antibody levels to other EBV-determined antigens, i.e. viral capsid (VCA) and early antigens (EA), and to measles and rubella viruses, to cytomegalovirus (CMV), and to toxoplasma gondii were also measured. The results of anti-EBV antibody titrations demonstrated that anti-VCA, anti-EA and anti-EBNA reactivity was significantly higher in HD patients than in healthy subjects. There was no significant difference between the distribution of high rubella and measles antibody titers in HD and control sera. The GMT and the incidence of high titer anti-CMV and toxoplasma antibodies were greater in HD patients than in controls. The analysis of the data, according to histological subtypes, showed that the condition of lymphocyte depletion was associated in HD patients with the highest anti-EBNA antibody levels and the lymphocyte predominance with the lowest. This pattern seemed to be peculiar for anti-EBV reactivity, since anti-CMV and anti-toxoplasma antibody levels in the lymphocyte-depleted group of patients did not significantly differ from those of controls. No correlation was found between anti-VCA and anti-EBNA in individual sera of HD patients. This observation suggests that different mechanisms are probably responsible in HD for the release of EBV-related antigen from infected cells.
