Popis: Summary Background The Epstein–Barr Virus (EBV) is truly prolific, with a prevalence of more than 90% in the adult human population. There are, however, little data available on the prevalence of EBV among patients with Inflammatory Bowel Disease (IBD), a population that is frequently immunosuppressed and thus at risk for severe, often fatal, primary infection. Aim To identify the prevalence of EBV in a population of patients with IBD and to compare it with that of the general population. Methods A database of 2500 IBD patients previously followed at the University of Alberta IBD Centre was queried; 60 of these patients were randomly chosen to participate. A total of 220 patients attending the IBD Centre for clinical appointment were also prospectively asked to participate. Participants completed serological testing for VCA-IgM, VCA-IgG and EBNA-IgG, to determine prior EBV exposure. Results A total of 263 patients underwent testing. Results for EBV seroprevalence of specific age groups were as follows: 18–20 years (n = 17), 29% seronegative; 21–25 years (n = 31), 29% seronegative; 26–30 years (n = 35), 31–35 years (n = 18) and 36–40 years (n = 25), 100% seropositive. Finally, 3% of those older than 40 (n = 117) were seronegative. EBV seroprevalence was similar for Crohn's disease and ulcerative colitis. Azathioprine was associated with seropositivity (P = 0.048). Conclusion The prevalence of EBV seronegativity in the IBD population aged 18–25 years was similar to that described in the general population, and above age 25 years, seropositivity approached 100%.
