Background: There are few data assessing treatment response in older eosinophilic esophagitis (EoE) patients and we evaluated treatment outcomes to topical corticosteroids (tCS) in this older population.
Methods: This retrospective cohort study of the UNC EoE Clinicopathologic database included subjects with a new diagnosis of EoE treated with tCS. Histologic responses, global symptom response, and endoscopic changes were recorded. Older EoE patients (≥65 years) were compared to younger EoE patients (<65).
Results: We identified 467 EoE patients treated with tCS, 12 (3%) of whom were ≥65 years. Compared to those <65 years, patients ≥65 had longer symptom duration and worse endoscopy scores, but most clinical features were similar. Post-treatment peak eosinophil counts trended higher in the <65 group (25.0 vs 5.5; p = 0.07). Histological response was greater in the ≥65 population at <15 eos/hpf (92% vs 57%; p = 0.02), ≤6 eos/hpf (83% vs 50%; p = 0.02), and <1 eos/hpf (58% vs 29%; p = 0.03). Older age was independently associated with increased odds of histologic response (adjusted OR 8.48, 95% CI: 1.08-66.4).
Conclusions: EoE patients ≥65 years had a higher likelihood of responding to tCS therapy, suggesting they should be studied more closely and included in future trials.
