Abstract

BACKGROUND AND AIMS: The incidence and prevalence of eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD) are rising with similar patterns. Co-occurrence of both diseases in the same patient has been increasingly reported. We sought to examine the pediatric population with both EoE and IBD to better understand the epidemiology and clinical implications of this overlap. METHODS: We conducted a retrospective case-control study at 2 tertiary care children's hospitals. Subjects with both EoE and IBD were identified and compared with randomly selected controls with EoE and IBD alone in terms of: demographics, atopic conditions, IBD classification, location and phenotype of Crohn disease (CD), IBD medications, endoscopic findings, and histopathology. Descriptive statistics summarized the data. RESULTS: Sixty-seven subjects with dual-diagnosis were identified across both institutions. The prevalence of IBD in the EoE population was 2.2% and EoE in IBD was 1.5%. Subjects with both diseases were more likely to have IgE-mediated food allergy compared with IBD alone (36% vs 7%, P < 0.001). Subjects with CD-EoE were less likely to have perianal disease than CD alone (2% vs 20%, P = 0.004). There was no difference in fibrostenotic EoE between the dual-diagnosis group and EoE alone. Treatment with a TNF-alpha inhibitor (anti-TNF) for management of preexisting IBD was protective against development of EoE with a relative risk of 0.314 [95% confidence interval [CI] 0.159-0.619]. CONCLUSIONS: This is a unique population in whom the underlying pathway leading to dual-diagnosis is unclear. Concomitant atopic conditions, especially IgE-mediated food allergy, and medication exposures, particularly anti-TNFs, may help predict likelihood of developing dual-diagnosis.
