title: Epstein-Barr virus infections in Brazil. II. Hodgkin's disease.
abstract: Sixty-seven cases of Hodgkin's disease (HD) occurring in São Paulo, Brazil, were studied. Males with HD predominated over females 2.3 to 1. Sixty-six percent of the cases occurred in patients under 30 years of age, 31.7% under 20 years of age, and only 7.5% after 50 years of age. Lymphocyte predominance and mixed cellularity histologic types were most common in patients less than 15 years old, and nodular sclerosis was most common in the 15- to 19-year-old group. Sera from all patients had antibody to the viral capsid antigen (VCA) of Epstein-Barr virus (EBV). The geometric mean titer (GMT) of VCA antibody with the use of Jijoye cells as antigen was 1:162, and 31.3% of patients had titers of 1:320 or more; in controls, the GMT was 1:67 and 3.8% had titers of 1:320 or more. Similar results were obtained when EB-3 cells were used as antigen. The highest titers occurred in males, in mixed cellularity and lymphocyte depletion forms, and in stage 2 of illness. EBV-specific IgM antibody and heterophile antibody levels were not elevated, but 20.5% of the HD patients had antibody to the early antigen of EBV present in their sera. Antibody levels for herpes simplex virus, cytomegalovirus, rubella, measles, parainfluenza viruses, and papovavirus were not significantly elevated over those in matched controls.
