Background
Eosinophilic esophagitis is an inflammatory condition in which eosinophil infiltration leads to esophageal remodeling and stricturing, with dilation therapy often needed. Achieving histologic remission reduces the need for repeat dilation, although little is known about the effects of long-term maintenance therapy.
Aims
To further assess the relationship between short-term histologic remission and maintenance therapy on need for repeat dilation in eosinophilic esophagitis.
Methods
A total of 77 patients with eosinophilic esophagitis (59.7% male; mean age 41.6 years) seen at a single medical center from June 2000 to August 2017 were included. Information on history of dilation and therapy [proton pump inhibitors (PPIs), steroids, elimination diet] was collected. Mean follow-up was 164 weeks. Fifty-one patients achieved histologic remission and 42 of these remained on maintenance therapy (23 PPIs, 14 topical steroids, and 5 dietary therapy). Standard phone interview was completed in cases with lack of follow-up. Only patients who underwent esophageal dilation to ≥ 17 mm were included.
Results
A significantly lower proportion of patients on maintenance therapy required repeat dilation (12/42) compared with patients not on maintenance therapy (8/9) (hazard ratio 0.12; p < 0.001). Of patients who received maintenance therapy, 9.1% required re-dilation. The difference in need for repeat dilation in patients who achieved histologic remission on therapy (14/26) versus those who did not (20/51) was not significant (hazard ratio 1.34; p = 0.45).
Conclusion
In a retrospective analysis of patients with eosinophilic esophagitis, we found that a significantly lower proportion who received maintenance therapy (PPIs, steroids, or dietary exclusions) required repeat dilation.
