Comparison of budesonide vehicles in inducing histologic remission in pediatric eosinophilic esophagitis

Abstract

ObjectivesOral viscous budesonide (OVB) is a common medication used to treat eosinophilic esophagitis (EoE). It is typically mixed with Splenda to produce a slurry, but other delivery vehicles have been used in clinical practice. We aimed to evaluate outcomes of pediatric EoE patients treated with OVB using different drug delivery vehicles.MethodsWe performed a retrospective chart review of pediatric EoE patients treated with OVB. The primary aim was to evaluate rates of histologic remission (defined by <15 eos/HPF in both mid and distal esophagus) after 6−12 weeks of OVB treatment for each delivery vehicle. Secondary aims were to evaluate histologic response and endoscopic response and remission of different delivery vehicles, and to compare the efficacy of different treatment regimens.ResultsA total of 111 patients were included in the study. Median treatment duration was 3.4 months. Overall rate of histologic remission with OVB was 52.6%. There was no difference in rates of histologic remission (p = 0.313) or response (p = 0.195 and p = 0.681 in mid and distal esophagus, respectively) among the different vehicle types or treatment regimens. Similarly, there was no difference in endoscopic remission and response among the different vehicle types (p = 0.853 and p = 0.727) or treatment regimens (p = 0.244 and p = 0.157). Patients who achieve histologic remission were more likely to be non‐Hispanic Caucasian.ConclusionOur findings suggest there is no difference in histologic and endoscopic outcomes with various delivery vehicles or combination therapy with OVB in the treatment of EoE. More palatable and cost‐effective vehicles can be used to treat EoE.
