The Effectiveness of Budesonide Once Daily as Maintenance Treatment of Eosinophilic Esophagitis.

Background: Swallowed topical corticosteroids (STC) are an effective first-line therapy for patients with eosinophilic esophagitis (EoE), both for induction and maintenance of remission. All interventional trials with STC used twice-daily dosing regimens. However, in other inflammatory gastrointestinal disorders, corticosteroids are given once daily (OD) with equal outcomes and improved compliance.

Goals: To evaluate the effectiveness of topical budesonide maintenance treatment in a once-daily dosing schedule.

Study: Retrospective analysis of confirmed patients with EoE, treated with topical budesonide as maintenance therapy OD, with adequate follow-up available. Patients currently treated with budesonide were contacted to fill out online questionnaires regarding symptoms and health-related quality of life (HRQOL). The primary end point was histologic remission, defined as peak eosinophil count (PEC) <15 eosinophils per high power field (HPF) after >12 weeks of budesonide OD.

Results: We included 29 patients on STC OD (1 mg, N=28; 0.5 mg, N=1), either budesonide orodispersible tablet (BOT, Jorveza, Dr. Falk Pharma; N=12) or budesonide viscous solution (BVS; N=17). After a median follow-up of 767 days on OD dosing (range: 103 to 2396), 86% of patients were in histologic remission. Four patients had histologic disease activity, of which one was treated with BOT. Two patients experienced a slight increase in PEC after dose reduction of BVS to OD (to PEC of 25 and 35/HPF, respectively). However, after switching the formulation to BOT OD they achieved histologic remission.

Conclusions: In this retrospective study, we demonstrated favorable results in the majority of patients treated with budesonide 1 mg OD as maintenance treatment for eosinophilic esophagitis.
