OBJECTIVE: To examine @entity15 ( @entity15 ) prevalence, rate of immunomodulatory treatment and frequency of @entity12732 ( @entity12732 ) antibodies in Vest-Agder, Norway. MATERIALS AND METHODS: @entity1 in the period 1996-2006 who met the Poser criteria for definitive or probable @entity15 were included. Clinical and demographical data, and presence of @entity12732 antibodies were registered. RESULTS: A total of 295 @entity1 were identified. The crude prevalence was 180 per 100,000 population (95% CI=160.9-218.0), age-adjusted prevalence was 186 per 100,000 population (95% CI=166.3-225.3). The age-adjusted incidence rates were 7.5 and 8.0 for 1996-2000 and 2001-2006, respectively. Thirty-eight per cent were treated with immunomodulatory agents when compared to 28% in the rest of the country. @entity12732 serum antibodies were detected in 7% of @entity1 with @entity15 . CONCLUSIONS: Vest-Agder county has the highest prevalence of @entity15 reported in Norway, and a high treatment rate. @entity12732 antibodies were not more prevalent than in healthy individuals.
