Prevalence of atopy is unrelated to presence of inflammatory bowel disease.
The prevalence of atopy (assessed by prick testing and serum IgE measurement), and of symptoms associated with atopy, has been defined in 122 patients with inflammatory bowel disease (IBD) and 103 age-matched controls. History analysis for atopic symptoms, and serum IgE levels, showed no differences between controls and IBD patients, or IBD subgroups (Crohn's disease, ulcerative colitis, ulcerative proctitis). Both in controls and in IBD patients, the prevalence of positive skin tests was higher in young people (aged less than 30) than in others; taking account of age distribution within the groups, there were no differences between controls and IBD patients, or subgroups, in the prevalence of positive skin tests. Our finding do not support the hypothesis that reaginic hypersensitivity plays a significant role in the pathogenesis of IBD.
