Background: In addition to the elimination diet, dietary composition may influence disease severity in patients with eosinophilic esophagitis (EoE) through modulation of the immune response. Aim: To explore the immunomodulatory role of nutrition before and during elimination diet in adult EoE patients. Methods: Nutritional intake was assessed in 39 Dutch adult EoE patients participating in the Supplemental Elemental Trial (Dutch trial registry NL6014, NTR6778) using 3‐day food diaries. In this randomized controlled trial, diagnosed patients received either a four‐food elimination diet alone (FFED) or FFED with addition of an amino acid‐based formula for 6 weeks. Multiple linear regression analyses were performed to assess associations between the intake of nutrients and food groups per 1000 kCal and peak eosinophil count/high power field (PEC), both at baseline and after 6 weeks. Results: At baseline, we found a statistically significant negative (thus favorable) relationship between the intake of protein, total fat, phosphorus, zinc, vitamin B12, folate, and milk products and PEC (p <.05), while calcium (p =.058) and full‐fat cheese/curd (p =.056) were borderline (favorably) significant. In contrast, total carbohydrates, prepacked fruit juice, and white bread were significantly positively (unfavorable) related to PEC (p <.05), while ultra‐processed meals (p =.059) were borderline (unfavorably) significant. After dietary intervention, coffee/tea were significantly negatively (favorably) related to PEC, hummus/legumes were significantly positively (unfavorably) related with PEC, while peanuts were borderline significantly positively related (p =.058). Conclusion: Dietary composition may be related to inflammation in adult EoE patients. High‐quality and anti‐inflammatory diets may be a promising adjuvant therapy in the dietary management of EoE.

Background: Elimination of key foods restricts dietary options in eosinophilic esophagitis (EoE) patients. Addition of amino acid‐based formula (AAF) to an elimination diet might facilitate adherence and, therefore, enhance efficacy of dietary management. Aim: To evaluate whether addition of AAF to a four‐food elimination diet (FFED) is more effective than FFED alone in decreasing eosinophilia, endoscopic signs, and clinical outcomes. Methods: This randomized controlled trial enrolled 41 adult patients with active EoE (≥15 eosinophils (eos) per high power field (hpf)) at baseline biopsy. Subjects were randomized (1:1 ratio) to groups given a FFED or FFED with addition of AAF providing 30% of their daily energy needs (FFED + AAF). Histological disease activity, endoscopic signs, symptoms, and disease‐related quality of life (EoEQoL) were measured at baseline and after 6 weeks of intervention. Results: Patients (60% male, age 34.5 (interquartile range (IQR) 29–42.8 years)) were randomized to FFED (n = 20) or FFED + AAF (n = 21); 40 participants completed the diet. Complete histological remission (<15 eos/hpf) was achieved in 48% of FFED + AAF subjects (n = 21) vs. 25% of FFED subjects (n = 20), respectively (p = 0.204). Peak eosinophil counts (PEC) decreased significantly in both groups between baseline and week 6, but the change in PEC between groups was not different (p = 0.130). A significant but similar endoscopic and symptomatic reduction was observed in both groups (all; p<0.05). Total EoEQoL scores significantly improved in the FFED + AAF group between baseline and week 6 (p = 0.007), and not in the FFED group. Conclusion: The addition of AAF to a FFED did not lead to a larger decrease in PEC between baseline and 6 weeks, but may result in a significant improvement of QoL in adult EoE patients NL6014 (NTR6778).

Background/Aims Growing evidence suggests a negative effect of eosinophilic esophagitis (EoE) on patients' general health-related quality of life (HRQOL). However, the relevance and use of coping strategies and its relation to (disease specific) HRQOL as well as its determinants have not been studied well. Methods Adult EoE patients were invited to complete standardized measures on general HRQOL (Short Form-36 Health Survey [SF-36]) and coping strategies (Utrechtse Coping Lijst [UCL]). Scores were compared to general population norms. The disease specific Adult Eosinophilic Esophagitis Quality of Life (EoE-QOL-A) measure was used to assess EoE-HRQOL. Socio-demographic-and clinical factors were also evaluated. Results In total, 147 adult EoE patients (61% males), age 43 (interquartile range, 29-52) years were analyzed. Mental health-scores (SF-36) were significantly lower in EoE patients, whereas physical health-scores (SF-36) were similar in EoE patients (vs the general population; P = 0.010 and P = 0.240), respectively. The subdomain "disease anxiety" (EoE-QOL-A) was mostly affected, determinants were; female gender, younger age, severe clinical disease activity, higher number of food bolus extraction, and more recent EoE-diagnosis. Less effective coping styles (ie, passive/palliative reaction) were associated with a significant impact on each individual EoE-HRQOLsubdomain as well as lower scores of the Mental Health Component Scale in male EoE patients. Passive reaction in female EoEpatients correlated with impairment of the EoE-HRQOL-domains "emotional impact" and "disease anxiety." Active problem solving was significantly related to better perception of mental HRQOL (SF-36) in both males and females. Conclusions EoE has a significant negative impact on mental HRQOL, with less effective coping strategies--specifically in males, being a relevant determinant. Thus, a pro-active approach towards coping mechanisms is needed in order to enhance HRQOL and manage patients' burden of EoE. [ABSTRACT FROM AUTHOR]

Background: Dysphagia is the main symptom of adult eosinophilic esophagitis (EoE). We describe a novel syndrome, referred to as "food‐induced immediate response of the esophagus" (FIRE), observed in EoE patients. Methods: Food‐induced immediate response of the esophagus is an unpleasant/painful sensation, unrelated to dysphagia, occurring immediately after esophageal contact with specific foods. Eosinophilic esophagitis experts were surveyed to estimate the prevalence of FIRE, characterize symptoms, and identify food triggers. We also surveyed a large group of EoE patients enrolled in the Swiss EoE Cohort Study for FIRE. Results: Response rates were 82% (47/57) for the expert and 65% (239/368) for the patient survey, respectively. Almost, 90% of EoE experts had observed the FIRE symptom complex in their patients. Forty percent of EoE patients reported experiencing FIRE, more commonly in patients who developed EoE symptoms at a younger age (mean age of 46.4 years vs 54.1 years without FIRE; P <.01) and in those with high allergic comorbidity. Food‐induced immediate response of the esophagus symptoms included narrowing, burning, choking, and pressure in the esophagus appearing within 5 minutes of ingesting a provoking food that lasted less than 2 hours. Symptom severity rated a median 7 points on a visual analogue scale from 1 to 10. Fresh fruits/vegetables and wine were the most frequent triggers. Endoscopic food removal was significantly more commonly reported in male patients with vs without FIRE (44.3% vs 27.6%; P =.03). Conclusions: Food‐induced immediate response of the esophagus is a novel syndrome frequently reported in EoE patients, characterized by an intense, unpleasant/painful sensation occurring rapidly and reproducibly in 40% of surveyed EoE patients after esophageal contact with specific foods.

Rationale: Data on the prevalence of mental distress among adult eosinophilic esophagitis (EoE) patients are scarce. Also, a significant gap remains in the understanding of which determinants are related to significant psychological symptoms and whether distressed patients require and receive mental care., Methods: Adult EoE patients were invited to complete standardized measures on anxiety/depressive symptoms (HADS) and general psychopathology (SCL-90-R). All scores were compared to general population norms. Socio-demographic and clinical factors were assessed., Results: In total, 147 adult EoE patients (61% males, age 43 (IQR 29-52) years were included (response rate 71%). No difference with general population values was found for total anxiety and depressive symptoms (7.8 ± 6.6 vs. 8.4 ± 6.3; p = 0.31). A total of 38/147(26%) patients reported high levels of anxiety and/or depressive symptoms (HADS-A ≥ 8: 35/147(24%) and HADS-D ≥ 8: 14/147(10%)), indicative of a possible psychiatric disorder. In a multivariate analysis, age between 18-35 years was independently associated with high levels of anxiety (HADS-A ≥ 8) (OR 3.0, 95% CI 1.3-6.9; p = 0.01). The SCL-90-R Global Severity Index (GSI) was significantly higher compared to the general population (p < 0.001). Significant signs of general mental distress (GSI ≥ 80th percentile) were observed in 51(36%) EoE patients, of which 29(57%) patients denied having any mental problems and only 8(16%) patients received mental care., Conclusion: A considerable proportion of adult EoE patients suffers from mental distress, with a 3-fold risk of significant anxiety in those patients younger than 35 years. Therefore, population-based studies are required and a proactive approach in the screening for and treatment of these psychological symptoms in EoE practice seems essential., (© 2020 The Authors.

Rationale: Eosinophilic esophagitis (EoE) has emerged from a case-reportable illness in the early 1990s to a distinct clinicopathological entity. Increasing worldwide incidences have been observed, although due to various study designs estimates are inconsistent., Aim: To determine population-based annual incidence rates over a time period of 25 years., Methods: A nationwide register-based pathology (PALGA) search was performed to identify reports describing esophageal eosinophilia between 1995 and 2019. EoE was identified if the diagnosis was confirmed by the pathologist. Crude incidence rates were estimated by the number of new EoE cases per year and matched with population data., Results: Between 1995 and 2019, 7361 unique patients' reports mentioned esophageal eosinophilia, of these 4061 were classified as EoE (71% male, mean age 37.9 ± 18.4 years). In total, 639 (16%) children (<18 years) were diagnosed. The EoE incidence increased from 0.01 in 1995 (95% CI: 0.0 - 0.04) to 3.16 (95% CI: 2.90 - 3.44) per 100.000 inhabitants in 2019. EoE was significantly more prevalent in males (OR 2.48 | 95% CI: 2.32 - 2.65; vs. females p < 0.001) and adults (OR 1.42 | 95% CI: 1.31 - 1.55; vs. children p < 0.001). Highest incidences were observed in 2019, being 4.37 (95% CI: 3.94 - 4.84) vs. 1.97 (95% CI: 1.68 - 2.29) per 100.000 males and females, respectively (p < 0.001). No seasonal variation was observed., Conclusion: Over the past quarter century, the annual rates of newly diagnosed EoE patients raised dramatically and this increase has not reached a deceleration yet., (© 2021 The Authors.
