Abstract
BACKGROUND: Few studies have examined combined or alternating treatment algorithms in eosinophilic esophagitis. AIMS: We conducted a retrospective cohort study to ascertain the efficacy and adherence to a combined and alternating treatment approach with topical corticosteroids and 2-food elimination diet for pediatric EoE. METHODS: Patients were prescribed a 2-food elimination diet (milk and soy) and topical corticosteroid (fluticasone or oral viscous budesonide) for 3 months, after which the steroid was discontinued and 2-food elimination diet continued for 3 months. An EGD was performed at baseline, 3 and 6 months. Clinical, endoscopic, and histologic data were extracted from electronic medical records. Nonparametric tests assessed adherence and outcomes. RESULTS: Twenty-nine eosinophilic esophagitis cases were included (mean age 11.5 years, 61% male). Complete adherence to combined therapy and 2-food elimination diet alone was 75 and 79%, respectively. Median eosinophil counts decreased from 51 to 2 eosinophils/hpf (p < 0.001) after combined treatment and rebounded to 31 (p = 0.07) after 2FED alone. Dysphagia improved after both the combined and 2-food elimination diet alone treatment approaches (52 vs. 11% and 10%; p = 0.001, 0.005). Nonsignificant improvements in endoscopic findings were documented across the length of follow-up. CONCLUSIONS: An initial combined treatment approach resulted in significant improvements in symptoms and histologic findings. While symptomatic improvements continued with 2-food elimination diet alone, the histologic improvement was not maintained. While loss to follow-up may obscure the efficacy of 2-food elimination diet alone, a combined/alternating treatment approach merits assessment in a larger prospective study.
