Topically applied mometasone furoate improves dysphagia in adult eosinophilic esophagitis - results from a double-blind, randomized, placebo-controlled trial.

OBJECTIVES: Topical corticosteroids are considered a cornerstone in the treatment of patients with eosinophilic esophagitis. The aim of this study was to evaluate the benefit of using mometasone furoate spray versus placebo on dysphagia and health-related quality of life in these patients. MATERIAL AND METHODS: Consecutive, newly diagnosed adult patients with eosinophilic esophagitis were randomized and treated with either 200 micrograms of orally administered topical mometasone furoate or placebo 4 times daily for 8 weeks. Symptoms and quality of life were evaluated using questionnaires including the Watson Dysphagia Scale, the European Organization for Research and Treatment of Cancer Quality of Life-Oesophageal Module 18 and the Short Form-36 before and after treatment. RESULTS: In the intention-to-treat analysis (n = 36) the Watson Dysphagia Scale score after mometasone treatment was reduced by 6.5 (median, p < .01) compared with 0 (median, ns) in the placebo group. The benefit of mometasone over placebo was significant (p < .05). In the per-protocol analysis (n = 33) the Watson Dysphagia Scale score was reduced by 5 (median, p = .01) after mometasone treatment compared with 0 (median, ns) in the placebo group. The advantage of mometasone over the placebo was significant (p < .05). The benefit of using mometasoneas evaluated by the two quality of life questionnaires was, however, insignificant. CONCLUSIONS: Our finding suggests that in adult patients with eosinophilic esophagitis, topical mometasone furoate exerts a beneficial effect compared with placebo regarding the main symptom, i.e., dysphagia. A corresponding benefit could not be verified regarding the various quality of life measurements.

Retrospective chart review: seasonal variation in incidence of bolus impaction is maintained and statistically significant in subgroups with atopy and eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) is a chronic inflammatory condition with eosinophilic infiltration of the esophageal mucosa. The most prominent symptom is dysphagia, which may result in esophageal bolus impaction in need of surgical extraction. To investigate whether an earlier reported seasonal variation in esophageal bolus impaction present only in a subgroup of patients with EoE and atopic disorders could be confirmed in this larger study. A single center retrospective chart review of patients who were diagnosed with esophageal bolus impaction between January 2004 and December 2017 was performed. Clinical, epidemiological and histologic data were collected. A total of 755 cases with esophageal bolus impaction were reviewed. A significantly higher occurrence of soft bolus impaction in summer and fall was shown in cases with confirmed EoE and in cases with atopy but not in the nonatopic group or in the group with a negative biopsy result. EoE was found in 48% of biopsied patients. A significant seasonal variation in cases with esophageal bolus impaction and concomitant atopy and EoE is confirmed, but the study design does not allow a causative role of allergens to be established.
