Abstract

Background Phenotypes of eosinophilic esophagitis (EoE) are not well characterized. Objective To describe clinical features of EoE patients with predefined phenotypes, determine predictors of these phenotypes, and make inferences about the natural history of EoE. Design Retrospective study. Setting Tertiary care center. Patients Incident EoE cases from 2001–2011 who met consensus diagnostic guidelines. Interventions n/a Main outcome measurements Endoscopic phenotypes, including fibrostenotic, inflammatory, or mixed. Other groups of clinical characteristics examined included atopy, level of esophageal eosinophilia, and age of symptom onset. Multinominal logistic regression assessed predictors of phenotype status. Results Of 379 cases of EoE identified, there were no significant phenotypic differences by atopic status or level of eosinophilia. Those with the inflammatory phenotype were more likely to be younger than those with mixed or fibrostenotic (13 vs 29 vs 39 years, respectively; p<0.001), and less likely to have dysphagia, food impaction, and esophageal dilation (p<0.001 for all). The mean symptom length prior to diagnosis was shorter for inflammatory (5 vs 8 vs 8 years; p=0.02). After multivariate analysis, age and dysphagia independently predicted phenotype. The OR for fibrostenosis for each 10-year increase in age was 2.1 (1.7–2.7). The OR for dysphagia was 7.0 (2.6–18.6). Limitations Retrospective, single-center study. Conclusions In this large EoE cohort, the likelihood of fibrostenosing disease increased markedly with age. For every ten year increase in age, the odds of having a fibrostenotic EoE phenotype more than doubled. This association suggests that the natural history of EoE is a progression from an inflammatory to a fibrostenotic disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
