An association between usage of tumor necrosis factor inhibitors (anti-TNF) in patients with inflammatory bowel disease (IBD) and other immune-mediated diseases and demyelinating diseases in the central nervous system has been suggested by case reports.1,2 However, it remains uncertain whether these cases are directly related to anti-TNF therapy because there is evidence of an underlying association be- tween demyelinating disease and IBD.3 In a nationwide population-based cohort, we compared rates of central demyelinating diseases among patients with IBD exposed and unexposed to anti-TNF.
