Patients with chronic illness affecting the esophagus often modify their eating habits to manage symptoms. Although this begins as a protective strategy, anxiety around eating can become problematic, and lead to poor outcomes. We administered a survey to examine the factors associated with problematic eating behaviors in patients who have reflux and difficulty swallowing (esophageal dysphagia).

In total, 277 adult patients aged above 18 diagnosed with achalasia, eosinophilic esophagitis, and gastroesophageal reflux completed an online survey: (1) demographic and disease information; (2) reflux and dysphagia severity (3) eating behaviors, as measured by a study-specific, modified version of the Eating Disorder Questionnaire (EDE-Q) for patients with esophageal conditions; and (4) Food related quality of life (FRQOL). Descriptive statistics, one-way ANOVA, and Pearson's correlations evaluated the sample data and a hierarchical linear regression evaluated predictors of problematic eating behaviors.

Problematic eating behaviors were associated with reflux severity, dysphagia severity, symptom anxiety, and hypervigilance, and negatively associated with FRQOL. While reflux and dysphagia severity predicted greater problematic eating, symptom anxiety explained more of these behaviors. Although hypervigilance and anxiety also predicted poorer FRQOL, problematic eating was the largest predictor.

Problematic eating behaviors are associated with increased symptom severity and symptom anxiety, and diminished FRQoL. Symptom anxiety, rather than symptom severity, appears to be a driving factor in problematic eating behaviors. Interventions aimed at diminishing symptom anxiety may be useful in reducing problematic eating behaviors in patients with gastrointestinal symptoms.

The goal of this Review is to discuss the clinical approach to patients who do not respond to treatment for eosinophilic oesophagitis (EoE). Refractory EoE is challenging to manage as there are limited data to guide decision-making. In this Review, refractory EoE is defined as persistent eosinophilia in the setting of incomplete resolution of the primary presenting symptoms and incomplete resolution of endoscopic findings following a PPI trial, and after treatment with either topical steroids or dietary elimination. However, this definition is controversial. This Review will examine these controversies, explore how frequently non-response is observed, and highlight potential explanations and predictors of non-response. Non-response is common and affects a large proportion of patients with EoE. It is important to systematically assess multiple possible causes of non-response, as well as consider treatment complications and an incorrect diagnosis of EoE. If non-response is confirmed, second-line treatments are required. Although the overall response rate for second-line therapy is disappointing, with only half of patients eventually responding, there are several promising agents that are currently under investigation, and the future is bright for new treatment modalities for refractory EoE.

Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by a marked eosinophilic infiltrate in the esophageal mucosa. What was once considered a rare disease has nowadays become one of the most frequent esophageal diseases in the Western countries, occupying a place just next to the gastroesophageal reflux disease. EoE etiology and pathogenesis remain largely unknown, although most studies consider that allergic and genetic factors play the most important role.

We report the case of EoE in an elderly male (octogenarian), giving a brief review of the current data related to epidemiology, pathogenesis, diagnosis, and treatment of the disease.

Dysphagia to solid foods was the leading symptom, and endoscopic findings included white exudates, longitudinal furrows, and concentric mucosal rings, all suggestive for EoE. Diagnosis relied on histological findings in esophageal mucosal biopsies (>30 eosinophils per high power field).He was treated with topical steroids for 8 weeks, symptoms improved gradually and the patient remained in remission at the 8-month follow-up.

This case emphasizes that EoE may occur in very old patients and gastroenterologists should have a high index of suspicion of this disorder in any elderly with dysphagia and endoscopic relevant features.

Eosinophilic oesophagitis (EoE) is a chronic immune-mediated disorder of the oesophagus. The incidence of EoE has been raised substantially and EoE has recently become the most prevalent cause of dysphagia among the adolescents. Food and aeroallergens are believed to play a major role in the pathogenesis. Current treatment includes topical steroids and dietary therapy. Dietary therapy with elimination of causative allergens could provide a durable long-term solution. Dietary therapy in EoE consists of in elemental and empiric elimination diets. Elemental diet with amino acid-based formula is most effective in achieving disease remission but poor taste makes adherence challenging. Empiric elimination diet based on avoidance of most common food allergens offers moderate response rates, the usefulness of allergy test-directed elimination diets is questioned by low response rates. In conclusion, dietary treatments for EoE seem promising, but further refinement is required before it can become standard care.

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease characterized pathologically by eosinophil infiltration. In addition to loss of barrier integrity, a dominant T Helper 2-associated immune response and strong allergic connection, the esophagus tissue undergoes dramatic changes, with frequent presence of mucosal rings, strictures, linear furrows, and trachealization. Although the inflammatory mechanisms behind this disease are being increasingly well understood, the structural features remain unexplained. We examined the expression of key members of the Wnt-signaling pathway in biopsies from patients with EoE. This pathway has been shown to be critically important in regulating cellular homeostasis, growth, and differentiation and to be dysregulated in several disease conditions. Biopsies from adult EoE patients were collected by endoscopy and mRNA extracted. After cDNA synthesis, the relative gene expression from key upstream (secreted frizzled-related protein 1) and downstream (c-myc and Cyclin D1) molecules in the Wnt pathway, as well as several Wnt pathway members (Wnt1, Axin1, low-density lipoprotein receptor-related protein 6, glycogen synthase kinase 3 beta, and β-catenin), were determined. Biopsies from patients with EoE displayed significantly higher expression of secreted frizzed-related protein 1 than controls, as well as reductions in Cyclin D1 and c-myc. In contrast, there were no differences in the Wnt pathway molecules. The levels of expression of Cyclin D1 and c-myc, as well as β-catenin, in EoE patients showed strong correlations with the frequency of esophageal eosinophils. Our findings suggest that although there are no changes in the overall levels of key Wnt pathway genes in adult EoE, there is evidence for dysregulation of upstream and downstream regulators of Wnt signaling. Importantly, the associations with eosinophilia suggest that these may participate in the pathogenesis of this disease and be markers of disease severity.
