Erratum to: Dysphagia and health-related quality of life in patients with eosinophilic esophagitis: a long-term follow-up

Eosinophilic esophagitis(EoE) is a chronic immune/antigen-mediated disease, with dysphagiaas the main symptom. The aim of this study was to survey symptoms and health-related quality of life in adult patients with EoE at least 1 year after diagnosis and a 2-month course of topical corticosteroids. Forty-seven consecutive patients [79 % males, mean age 49 years (range 18–90 years)] were evaluated using three different questionnaires at three different occasions: the Watson DysphagiaScale (WDS), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire–Oesophageal Module 18 (EORTC QLQ-OES18) and the Short Form-36 ( SF-36). The median time from diagnosis to the long-term follow-up was 23 months (range 12–34 months). The WDS scores and the EORTC QLQ-OES18 Dysphagiaand Eating scale scores were improved after 2 months of treatment (p = 0.00007, p = 0.01, p = 0.004, respectively), as were the long-term follow-up scores (p = 0.01, p = 0.03, p = 0.005, respectively), relative to the scores at diagnosis. In addition, the EORTC QLQ-OES18 Choking scores were improved after the steroid course (p = 0.003) but not after the long-term follow-up. No significant differences were detected with respect to the SF-36scores. In summary, EoE seems to be associated with a substantial burden of symptoms that improve significantly after treatment. A partial remission persists more than 1 year after diagnosis and the discontinuation of medication. The WDS and the EORTC QLQ-OES18 appear to be sensitive instruments appropriate for surveillance in these patients.
