The serologic panel for inflammatory bowel disease (IBD) is rapidly expanding. Antineutrophil cytoplasmic antibodies (ANCA) and anti-Saccharomyces cerevisiae mannan antibodies (ASCA) have remained the most widely studied markers, but immune reactivity against a new group of bacterial antigens such as I2, OmpC (outer membrane porin C), and flagellin, has been described in Crohn’s disease. Several clinical avenues have been explored, such as the usefulness of serologic markers as screening tools for IBD and in accelerating a diagnosis in patients with indeterminate colitis. Another area of interest is disease stratification. Emerging data suggest there is a diversity of qualitative and quantitative responses to environmental antigens that differs among groups of IBD patients and may be associated with different clinical behaviors. As a result, it may be possible to tailor therapy on the basis of serologic responses. Prospective studies are needed before translating this concept into clinical practice. Clustering of IBD patients into more homogeneous subgroups based on antibody responses may help to unravel the pathophysiology of subsets of IBD.

An outstanding study in which serologic expression cloning was used to identify an immunodominant antigen, CBir1 flagellin, to which strong B-cell and CD4+ T-cell responses occur in colitic mice. Approximately 50% of patients with Crohn’s disease had serum reactivity to CBir1, whereas ulcerative colitis patients and control subjects had little or no reactivity. CBir1 is the first bacterial antigen inducing colitis in animals that also demonstrates an abnormal immune response in IBD.PubMedCrossRefGoogle Scholar

The only prospective study that assessed the usefulness of serologic markers in indeterminate colitis. Ninety-seven patients with an initial diagnosis of indeterminate colitis were analyzed for ANCA and ASCA. After a mean of 1 year of follow-up, a definitive diagnosis was reached in 31 of 97 (32%) patients. ASCA+/ANCA-predicted Crohn’s disease in 80% of indeterminate colitis patients, whereas ASCA-/ANCA+ was predictive for ulcerative colitis in 64%. Nevertheless, 48.5% of indeterminate colitis patients did not have antibodies against ASCA or ANCA, thus limiting the clinical utility of serologic testing. The majority of these patients remain as having indeterminate colitis during their further clinical course, perhaps reflecting a distinct clinico-serologic entity.PubMedCrossRefGoogle Scholar
