Background and Aims: Dysphagia is the hallmark symptom in eosinophilic esophagitis (EoE). However, data are limited regarding the overall prevalence and potential implications of atypical symptoms like odynophagia and retrosternal pain. Methods: Patients enrolled into the Swiss EoE cohort study (SEECS) were analyzed regarding the presence of odynophagia and retrosternal pain. Demographics, other EoE-related symptoms, histologic and endoscopic activity were compared between EoE-patients with vs. without odynophagia and/or retrosternal pain. Results: 474 patients (75.2% male) were analyzed. In their individual course of disease 110 (23.2%) patients stated to have ever experienced odynophagia and 64 (13.5%) retrosternal pain independent of food intake, 24 (5%) patients complained about both symptoms. Patients with odynophagia consistently scored higher in symptom severity (p < 0.001), EREFS score (median 3.0 vs. 2.0, p = 0.006), histologic activity and a lower quality of life (p = 0.001) compared to patients without odynophagia. Sex, age at diagnosis, EoE-specific treatment, complications such as candida or viral esophagitis and disease duration were similar in patients with vs. without odynophagia. Also patients with retrosternal pain scored higher in symptom severity (2.0 vs. 1.0, p = 0.001 and 2.0 vs. 1.0, p < 0.001 in physician and patient questionnaire assessment, respectively). However, there was neither a difference in endoscopic/histologic disease activity nor in quality of life according to presence or absence of retrosternal pain. Due to logistic reasons, a stratification regarding the presence of concomitant dysphagia was not possible. Conclusion: Odynophagia and swallowing-independent retrosternal pain are common symptoms in patients with EoE, associate with an overall higher EoE-related symptom severity and for the case of odynophagia lower quality of life. However, the influence of concomitant dysphagia and its severity remains unclear and needs to be included in future analyses. [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.

Background and Aims: Monoclonal antibodies (MAbs) have clinical benefits for treating several atopic diseases. However, consensus on its use for eosinophilic esophagitis (EoE) is lacking. The present meta-analysis aimed to compare the efficacy and safety of MAbs versus placebo for treating EoE. Methods: We searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs). The primary outcomes were changes in peak esophageal eosinophils count/high power field (HPF) and mean esophageal eosinophils count/HPF. The secondary outcomes were changes in the EoE-Histology Scoring System (EoE-HSS), Endoscopic Reference Score (EREFS), dysphagia score, and adverse events (AEs). We compared binary outcomes using risk ratio (RR) and continuous outcomes using mean difference (MD) or standardized mean difference (SMD), with 95% confidence interval (CI). Considering the diversity of mechanistic properties of MAbs, a pre-specified subgroup analysis by MAb mechanism of action was performed for all outcomes, provided that at least two studies were in each subgroup. Heterogeneity was assessed using Cochran's Q test and I2 statistics. Results: 6 RCTs were included (533 patients). Compared to placebo, MAbs led to a significant reduction in peak esophageal eosinophils count/HPF (MD -0.78; CI 95% -0.87, -0.6801) and mean esophageal eosinophils count/HPF (SMD -0.79; CI 95% -1.5, -0.08). Moreover, MAbs significantly reduced EoE-HSS scores (grade score: SMD -9.31; 95% CI -13.95, -4.6701; stage score: SMD -10.18; 95% CI -15.06, -5.31), EREFS (SMD -5.95; CI 95% -9.19, -2.71) and dysphagia score (SMD -1.79; CI 95% -3.36, -0.23) without increasing AEs compared to placebo. Among those MAbs whose mechanism of action includes the blockage of the receptor for IL-13 (Dupilumab, QAX576, and RPC4046), the scores of EoE-HSS grade, EoE-HSS stage, EREFS, and dysphagia were significantly reduced, and they presented a similar risk of overall and serious AEs compared to placebo. Conclusion: MAbs seem effective and safe in reducing esophageal eosinophil infiltrate, EoE-HSS score, EREFS score, and dysphagia symptoms in patients with EoE. However, further evidence is needed to establish its place in EoE management. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Eosinophilic esophagitis (EoE) is associated with atopy; however, recent studies have identified an association with food-specific immunoglobulin G4 (FS-IgG4) rather than immunoglobulin E antibodies. This study aimed to evaluate the role of serum FS-IgG4 in guiding an elimination diet and its outcomes. METHODS: Patients with and without EoE were enrolled in a prospective, controlled, single tertiary center trial. Serum FS-IgG4 titers, esophageal eosinophil counts, and dysphagia symptom questionnaire scores were assessed, and participants with elevated FS-IgG4 (ImmunoCAP, cutoff of 10 mgA/L) commenced 6-week targeted elimination diet. Repeat serum FS-IgG4 and endoscopic and histologic examination were performed at 6-week follow-up. RESULTS: Twenty-two patients with active EoE and 13 controls were recruited. Serum FS-IgG4 to milk, wheat, soy, eggs, and nuts was significantly higher in EoE (P = 0.0002, P = 0.002, P = 0.003, P = 0.012, and P < 0.001, respectively). Elevated serum FS-IgG4 to 1 or more food groups (median 2) was identified in 21/22 (95.4%) patients with EoE; 20/21 underwent 6-week dietary elimination. Median reductions in dysphagia symptom questionnaire score and EoE endoscopic reference score after elimination were 8 (P = 0.0007) and 1 (P = 0.002), respectively. Nine (45%) patients had histological remission (<15 eosinophils per high-power field). Fall in median esophageal eosinophil count was not statistically significant (50 vs 23; P = 0.068). Serum FS-IgG4 did not decline by 6-week follow-up. DISCUSSION: Serum FS-IgG4 to milk, wheat, soy, egg, and nuts was present at higher levels in EoE, with targeted elimination resulting in 45% histologic remission rate. Serum FS-IgG4 has potential as a noninvasive biomarker in EoE. When successful, FS-IgG4 -led elimination diet can negate need for medications and be viewed more favorably by patients because of its smaller endoscopic burden compared with empirical elimination diets.

A 16-year-old Caucasian male with previously diagnosed eosinophilic esophagitis (EoE) 4 years before his initial visit to an allergist-immunologist, scheduled due to severe dysphagia and recurrent food impaction. He had been off EoE therapy for 1 year. After resuming inhaled fluticasone and a proton pump inhibitor (PPI), esophagogastroduodenoscopy (EGD) was immediately scheduled. The dates of the original EGD procedures with the histological summary and EoE therapy are reported in the Table 1. The fourth endoscopy revealed near normal histology, with rare candida staining (Table 1). He was continued on daily PPI and the fluticasone was discontinued. Three weeks of Fluconazole failed to resolve his dysphagia. A repeat barium swallow confirmed a pre-existing cricopharyngeal bar, and he was referred to an otolaryngology for further care. Table 1.

Background: Eosinophilic oesophagitis (EOE) is a known cause of food bolus obstruction (FBO) with rising incidence and prevalence. Aims: To assess the rates of EOE in adult cases presenting with an FBO via prospective biopsy collection during index endoscopy. Methods: Oesophageal FBO cases requiring gastroscopy between February 2014 and January 2021 at a single institution with a unified policy to perform biopsies on FBO cases were analysed using medical records, endoscopy and histology. Statistical analysis was undertaken to compare those with and without EOE as their final diagnosis, including the timing of oesophageal biopsy and the season that cases presented. Results: One hundred ninety FBO presentations were analysed, 15 patients presented twice and one patient presented four times within the 7‐year study period. Men represented 72% of cases. A total of 78% of cases had biopsies collected at an index or scheduled follow‐up endoscopy. EOE was the cause of the FBO in 28% (53/190) of presentations. FBO secondary to EOE was more likely to occur in the spring and summer months (Australian September to March), with 39% (19 of 49) of cases presenting in spring attributable to EOE. Conclusion: EOE affects a significant proportion of patients presenting with FBO (28%); a high biopsy rate of 78% in FBO cases provides an opportunity for prompt diagnosis and treatment.

The article deals with the reliability of the eosinophilic oesophagitis histological scoring system (EOE-HSS) to predict treatment status. Eosinophilic oesophagitis is considered as the most common cause of dysphagia and food impaction in young patients and if left untreated, it can lead to fibrostenotic disease and oesophageal strictures. An article on the reliability of EOE-HSS published in previous issue of the journal is applauded for its contribution to the subject.

INTRODUCTION: Differences in eosinophilic esophagitis (EoE) presentation and outcomes by ethnicity or race remain understudied. We aimed to determine whether EoE patients of Hispanic/Latinx ethnicity or non-White race have differences in presentation at diagnosis or response to topical corticosteroid (tCS) treatment. METHODS: This retrospective cohort study included subjects of any age with a new diagnosis of EoE and documentation of ethnicity or race. For those who had treatment with tCS and follow-up endoscopy/biopsy, we assessed histologic response (<15 eosinophils/hpf), global symptom response, and endoscopic response. Hispanic EoE patients were compared with non-Hispanics at baseline and before and after treatment. The same analyses were repeated for White vs non-Whites. RESULTS: Of 1,026 EoE patients with ethnicity data, just 23 (2%) were Hispanic. Most clinical features at presentation were similar to non-Hispanic EoE patients but histologic response to tCS was numerically lower (38% vs 57%). Non-White EoE patients (13%) were younger at diagnosis and had less insurance, lower zip code-level income, shorter symptom duration, more vomiting, less dysphagia and food impaction, fewer typical endoscopic features, and less dilation. Of 475 patients with race data treated with tCS, non-Whites had a significantly lower histologic response rate (41% vs 59%; P = 0.01), and odds of histologic response remained lower after controlling for potential confounders (adjusted odds ratio 0.40, 95% confidence intervals: 0.19-0.87). DISCUSSION: Few EoE patients at our center were Hispanic, and they had similar clinical presentations as non-Hispanics. The non-White EoE group was larger, and presentation was less dysphagia-specific. Non-White patients were also less than half as likely to respond to tCS. [ABSTRACT FROM AUTHOR]

Background: Recent studies have evaluated the upper esophageal sphincter (UES) with high-resolution manometry (HRM) in some esophageal diseases, but not eosinophilic esophagitis (EoE). The aim of our study was to evaluate the function of the UES across EoE, gastroesophageal reflux disease (GERD), functional dysphagia (FD), and the relationship with esophageal symptoms, esophageal body contraction, and esophagogastric junction (EGJ) metrics. Methods: HRM was performed on 30 EoE, 18 GERD, and 29 FD patients according to the Chicago Classification 3.0. The study data were exported to the online analysis platform Swallow Gateway. The UES was assessed in terms of UES Resting Pressure (UES-RP), UES Basal Pressure (UES-BP), UES Integrated Relaxation Pressure (UES-IRP), UES Relaxation Time (UES-RT), Basal UES Contractile Integral (Basal UES-CI), Post-Deglutitive UES Contractile Integral (Post-Deglutitive UES-CI), and Proximal Contractile Integral (PCI). Results: ANOVA analysis showed significantly higher values of Post-Deglutitive UES-CI in EoE patients compared with FD patients (p = 0.001). Basal UES-CI and UES-RP showed significantly higher values in EoE (p = 0.002, p = 0.038) and GERD (p < 0.001, p = 0.001) patients compared with FD patients. Correlations between LES-CI and Post-Deglutitive UES-CI, Basal UES-CI, and UES-RP (p ≤ 0.001, p = 0.027, p = 0.017, respectively), and between LES-BP and Post-Deglutitive UES-CI (p = 0.019), independent of diagnosis, were shown. No correlations have been demonstrated between the UES, EGJ metrics, and esophageal symptoms. Conclusions: Some differences in UES metrics in the three different diseases were found. Further studies are needed to confirm the results of our pilot study and possible applications in clinical practice. [ABSTRACT FROM AUTHOR]

Background: Symptoms of vomiting and dysphagia in children with eosinophilic esophagitis may be related to the development of mucosal fibrosis.Aim: Our aims were to (1) investigate esophageal fibrosis in children with EoE compared to patients with gastroesophageal reflux disease and normal individuals, and (2) to assess the degree of mucosal fibrosis in patients with EoE before and after medical treatment.Methods: A retrospective analysis of esophageal biopsies from patients with EoE, GERD, and normal mucosa was performed. Demographic data, clinical information, eosinophil number, and sub-epithelial fibrosis was compared among the groups. A similar comparison was performed in EoE patients, before and after therapy.Results: Esophageal biopsies from 53 children were included, of which 17 with EoE, 17 GERD, and 19 were normal. A significantly higher number of eosinophils and greater fibrosis was found in EoE patients vs. GERD and normal (fibrosis grade 2: 13 patients in the EoE group vs. one patient for each control group; p=0.0001). After therapy, a significant decrease in fibrosis and eosinophils number was noted in EoE patients [fibrosis grade 2: 10 (71.5%) patients vs. one (7.1%) patient, and eosinophil count was 35.5/HPF vs. 13.4/HPF, pre- and post-therapy, respectively; p<0.05]. The decrease in esophageal fibrosis paralleled the improvement in the related clinical symptoms.Conclusion: A higher degree of esophageal fibrosis was found in patients with EoE compared to GERD or normal esophagus. Conventional therapy in EoE improved obstructive symptoms, decreased eosinophils count, and reversed the degree of fibrosis. We suggest that appropriate therapy in patients with EoE will improve clinical symptoms and histology. [ABSTRACT FROM AUTHOR]

Background: Mixed and non‐IgE‐mediated food allergy is a subset of immune‐mediated adverse food reactions that can impose a major burden on the quality of life of affected patients and their families. Clinical trials to study these diseases are reliant upon consistent and valid outcome measures that are relevant to both patients and clinicians, but the degree to which such stringent outcome reporting takes place is poorly studied. Objective: As part of the Core Outcome Measures for Food Allergy (COMFA) project, we identified outcomes reported in randomized clinical trials (RCT) of treatments for mixed or non‐IgE‐mediated food allergy. Design: In this systematic review, we searched the Ovid, MEDLINE and Embase databases for RCTs in children or adults investigating treatments for food protein‐induced enterocolitis syndrome, food protein‐induced allergic proctocolitis, food protein‐induced enteropathy and eosinophilic gastrointestinal disorders including eosinophilic esophagitis [EoE], eosinophilic gastritis and eosinophilic colitis published until 14 October 2022. Results: Twenty‐six eligible studies were identified, with 23 focused on EoE (88%). Most interventions were corticosteroids or monoclonal antibodies. All EoE studies assessed patient‐reported dysphagia, usually using a non‐validated questionnaire. Twenty‐two of 23 EoE studies used peak tissue eosinophil count as the primary outcome, usually using a non‐validated assessment method, and other immunological markers were only exploratory. Thirteen (57%) EoE studies reported endoscopic outcomes of which six used a validated scoring tool recently recommended as a core outcome for EoE trials. Funding source was not obviously associated with likelihood of an RCT reporting mechanistic versus patient‐reported outcomes. Only 3 (12%) RCTs concerned forms of food allergy other than EoE, and they reported on fecal immunological markers and patient‐reported outcomes. Conclusions: Outcomes measured in clinical trials of EoE and non‐IgE‐mediated food allergy are heterogeneous and largely non‐validated. Core outcomes for EoE have been developed and need to be used in future trials. For other forms of mixed or non‐IgE‐mediated food allergies, core outcome development is needed to support the development of effective treatments.

Background: The Swedish Watson Dysphagia Scale (S-WDS) has been used to assess dysphagia in patients with eosinophilic esophagitis (EoE) but has not been validated for this patient group. The aim of this study was to validate the S-WDS for adult patients with EoE. Methods: Ninety-seven Swedish adult patients with EoE and 97 controls without dysphagia filled out the S-WDS, the Swedish Eosinophilic Esophagitis Activity Index (S-EEsAI) and a set of supplementary questions. The reliability of the S-WDS was evaluated using Cronbach's alpha, Pearson correlation of items and total score, and test–retest analysis (n  = 29). Validity was investigated using Spearman correlations of the S-WDS items, S-EEsAI domains and a self-assessment score, and by investigating floor and ceiling effects. Results: The Cronbach's alpha of the S-WDS was 0.77 and all items demonstrated moderate to strong correlation to the S-WDS score (r  = 0.40–0.81) indicative of sufficient reliability of the instrument. In addition, the test–retest results reflected excellent reliability with an intraclass correlation coefficient of 0.85 for the S-WDS score. Adequate validity of the instrument was demonstrated, the S-WDS score correlated moderately with the self-assessment score and with 4/6 S-EEsAI domains, and strongly with the remaining two domains. Floor effects were more common for liquids and soft-textured foods and ceiling effects increased with increasing food consistency. The S-WDS scores of the patient group were significantly different from those of the nondysphagia control group (P  < 0.001). Conclusion: The S-WDS instrument is an appropriate and valid instrument for assessment of dysphagia in patients with EoE. [ABSTRACT FROM AUTHOR]

Background: Endoscopic features of eosinophilic esophagitis (EoE) are measured using the validated EoE Endoscopic Reference Score (EREFS); however, a threshold for treatment response has not been defined. We aimed to determine a cut-point for endoscopic response as measured by EREFS.Methods: We performed a secondary analysis of a randomized clinical trial comparing budesonide slurry with swallowed fluticasone multidose inhaler for initial treatment of EoE. In the parent trial, EREFS was determined before and after treatment (score range 0-9), as were histologic findings and dysphagia symptoms. We performed tabular, flexible trend, and dependent mixture analyses of measures of treatment response to select the best clinical EREFS threshold.Results: In the 111 included patients (mean age 39 years; 67 % male; 96 % white), an EREFS threshold of ≤ 2 was 80 % sensitive (95 % confidence interval [CI] 69 % to 88 %) and 83 % specific (95 %CI 67 % to 94 %) for histologic response (peak of < 15 eosinophils per high-power field). Flexible trend analysis and dependent mixture modeling similarly suggested that a threshold of ≤ 2 best captured the correlation of EREFS with histologic and symptomatic measures. Dependent mixture modeling found near-total membership in the response class at EREFS of 0 or 1 and > 75 % at EREFS of 2 or 3.Conclusions: An EREFS of ≤ 2 was the best clinical threshold for endoscopic response to topical steroid treatment, and was consistent with clinical and histologic response. Therefore, future studies can report a binary outcome of endoscopic response when EREFS is 2 or less. [ABSTRACT FROM AUTHOR]

Introduction: Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disorder manifested by symptoms of impaired esophageal function and hypereosinophilic esophageal inflammation. It is believed that the number of patients being diagnosed globally is increasing. Aim: To describe the frequency and clinicopathological features of EoE in Jordanian children. Material and methods: A retrospective review of all paediatric patients with eosinophilic esophagitis diagnosed and followed up at our paediatric gastroenterology service at King Abdullah University Hospital between January 2015 and January 2020. Results: During the study period, 21 patients were diagnosed with EoE out of 700 diagnostic endoscopic procedures. Only 1 (4.8%) female was diagnosed. The average age at presentation was 9.5 years (age range: 1-16 years). The most common manifestation was solid food dysphagia (15, 71.4%), followed by food impaction and vomiting (11, 52.4% and 6, 28.6%, respectively). Atopy was diagnosed in 10 (47.6%) patients. Four (19.0%) had food allergy, 3 (14.3%) had respiratory allergy, and 3 (14.3%) had combined. Linear furrows and circular rings were the most common endoscopic features - 17 (81.0%) and 10 (47.6%), respectively, while papillary elongation, basal zone hyperplasia, and eosinophilic infiltrate were the most common reported histopathological features. Almost all patients received proton pump inhibitors (19, 90.5%). Steroids were used in 18 (85.7%) patients; local steroids in 11 (52.4%), and oral steroids in 7 (33.3%). Out of the 4 (19%) patients with esophageal strictures, 2 (9.5%) required pneumatic dilatation. Conclusions: Eosinophilic esophagitis is not uncommon in our community. Clinical and histological parameters point to delayed referral and diagnosis. Increasing awareness of this problem will lead to early diagnosis and will decrease complications.

Eosinophilic esophagitis (EoE) is an inflammatory condition of the esophagus that causes symptoms of esophageal dysmotility. Patients with feeding or eating disorders (ED) can have similar symptoms, and there is a paucity of literature exploring these similarities. Furthermore, EoE can occur in addition to an ED, requiring clinicians to obtain a thorough history, make accurate diagnoses, and adequately treat all underlying conditions. We present 4 pediatric cases highlighting the similarities between EoE and ED symptomatology. Patients 1 to 3 were presumed to have an ED and were subsequently diagnosed with EoE. Patient 4 had a history of previously diagnosed and inadequately treated EoE, but was later found to also have a longstanding ED. The patients presented to the University of Rochester Pediatric Ambulatory Clinics in 2020. This series demonstrates that symptoms of EoE can overlap with those of an ED, such as anorexia nervosa or avoidant restrictive food intake disorder. Therefore, assessment for either EoE or an ED should include questions related to both diagnoses. Symptoms that may raise suspicion of EoE are indigestion, acute (versus chronic) weight loss, and dysphagia, including the inability to swallow pills, particularly in the presence of personal or family history of atopy. Patients with known EoE should be periodically evaluated for the presence of an ED. This case series illustrates that EoE can either present as an ED or complicate the diagnosis and/or treatment of an ED, making prompt diagnosis and treatment essential for successful management of all conditions.

Eosinophilic esophagitis (EoE) is a leading cause of food bolus impaction in children and adults. The mechanism of dysphagia in EoE, particularly non-obstructive dysphagia, remains incompletely understood. While fibrostenotic processes appear to be critical in the development of dysphagia, somatosensory dysfunction and dysmotility also contribute. This review considers potential mechanisms of dysphagia and evaluates the utility of current and future treatment strategies in this context. [ABSTRACT FROM AUTHOR]

Background: Eosinophilic esophagitis (EoE) is a progressively documented disorder in adults presenting with dysphagia and chest pain. EoE is featured by eosinophilic infiltration of the Esophageal mucosa; its pathogenesis is unknown. All patients with suspected EoE must undergo Esophageal mucosal biopsies to confirm the diagnose. Endoscopy had certain but variant features among EoE cases. Objective: This study aimed to identify the epidemiologic characteristics and clinical pattern of Eosinophilic Esophagitis in a single centre, Aseer region, Saudi Arabia. Methods: A record based retrospective study was conducted targeting all patients diagnosed with eosinophilic esophagitis in ACH during the period from 1990 to 2021. Data were extracted using pre-structured data extraction sheet to avoid data extraction error. Data extracted included patients' demographic data, past medical history, presenting clinical symptoms, laboratory findings, endoscopic findings, biopsy results, and medications prescribed. Data extracted were filtered and then fed to excel sheet for raw data presentation. Results: A total of 91 patients fulfilling the inclusion criteria were reviewed. Patients ages ranged from 6 to 65 years with mean age of 26.6 12.5 years old. Exact of 79 (86.8%) patients were males. The most reported clinical symptom was dysphagia (67%), followed by food impaction (33%), Barret's oesophagus (14.3%), and heartburn (3.3%). The most frequent Endoscopic findings were wrings (41%), followed by Trachealization (38%), linear grove (31%), stricture (29%), white exudate (27%), esophagitis (19%), mucosal oedema (10%), and oesophageal ulcer (9%). Conclusion: In conclusion, the study showed that, EoE was more among males in their middle age with eating disorders due to dysphagia, and food impaction. These clinical complaints were associated with oesophageal changes and functional disability due to inflammatory changes with wrings, and strictures. [ABSTRACT FROM AUTHOR]

Background Eosinophilic esophagitis (EoE) is a chronic allergic inflammatory condition causing recurrent dysphagia and may predispose patients to repeated hospitalizations. We assessed temporal trends and factors affecting readmissions in patients with EoE. Methods Patients with primary diagnosis of EoE and/or a complication (dysphagia, weight loss, and esophageal perforation) from EoE between 2010 and 2017 were identified from the National Readmissions Database using the International Classification of Diseases codes. The primary outcome was incidence of EoE related 30-day readmission. Independent risk factors for readmissions were evaluated using multivariable logistic regression analysis. Secondary outcomes were temporal trends of readmissions and healthcare costs. Results Of the 2,676 (mean age 45 ± 17.8 years, 1,667 males) index adult admissions, 2,103 (79%) patients underwent an upper endoscopy during the admission. The mean length of stay (LOS) was 3 ± 3.7 days. The 30-day readmission rate was steady at 6.8% from 2010 to 2017 and majority of the readmissions occurred by day 10 of index discharge. Age > 70 years was associated with a higher trend in 30-day readmission (P  < 0.001). Longer LOS, history of smoking and the presence of eosinophilic gastroenteritis predicted readmission. Conversely, a history of foreign body impaction and upper endoscopy (including esophageal dilation) at index admission were negatively associated with readmission. Mean hospital charges significantly increased from $24,783 in 2010 to $40,922 in 2017. Conclusion Readmissions due to EoE are more likely to occur in the first 10 days of discharge and at a lesser rate when upper endoscopies are performed at the index admission. [ABSTRACT FROM AUTHOR]

Eosinophilic esophagitis is a relatively recently discovered disease of increasing incidence and prevalence and is a common cause of dysphagia and food bolus impaction. The definition of eosinophilic esophagitis continues to evolve, most recently with the characterization of proton pump inhibitor-responsive esophageal eosinophilia. The number of high-quality prospective, controlled trials guiding therapeutic decisions in eosinophilic esophagitis has increased steadily over the past several years. Treatment options at present focus on dietary therapy, particularly implementation of a 6-food elimination diet, and medical therapy, primarily the use of swallowed, topical corticosteroids. Proton pump inhibitors play an important role in current management. Conservative esophageal dilation is effective at ameliorating dysphagia in symptomatic patients with esophageal strictures. We conducted an evidence-based review of the diagnosis and treatment options in adults with eosinophilic esophagitis. The understanding of eosinophilic esophagitis continues to be refined. Continued validation of appropriate endpoints, however, is essential to establish the efficacy of existing and novel therapeutic approaches. [ABSTRACT FROM AUTHOR]

Importance: Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory disease of the esophagus that affects an estimated 34.4/100 000 people in Europe and North America. EoE affects both children and adults, and causes dysphagia, food impaction of the esophagus, and esophageal strictures.Observations: EoE is defined by symptoms of esophageal dysfunction, such as vomiting, dysphagia, or feeding difficulties, in a patient with an esophageal biopsy demonstrating at least 15 eosinophils per high-power field in the absence of other conditions associated with esophageal eosinophilia such as gastroesophageal reflux disease or achalasia. Genetic factors and environmental factors, such as exposure to antibiotics early in life, are associated with EoE. Current therapies include proton pump inhibitors; topical steroid preparations, such as fluticasone and budesonide; dietary therapy with amino acid formula or empirical food elimination; and endoscopic dilation. In a systematic review of observational studies that included 1051 patients with EoE, proton pump inhibitor therapy was associated with a histologic response, defined as less than 15 eosinophils per high-power field on endoscopic biopsy, in 41.7% of patients, while placebo was associated with a 13.3% response rate. In a systematic review of 8 randomized trials of 437 patients with EoE, topical corticosteroid treatment was associated with histologic remission in 64.9% of patients compared with 13.3% for placebo. Patients with esophageal narrowing may require dilation. Objective assessment of therapeutic response typically requires endoscopy with biopsy.Conclusions and Relevance: EoE has a prevalence of approximately 34.4/100 000 worldwide. Treatments consist of proton pump inhibitors, topical steroids, elemental diet, and empirical food elimination, with esophageal dilation reserved for patients with symptomatic esophageal narrowing.

Background: The relationship between histologic disease activity in eosinophilic esophagitis (EoE) and generic measures of quality of life (QoL) is unclear. Aims: To determine differences in QoL in adults with EoE based on histologic activity and assess changes in QoL over time. Methods: We performed an analysis of prospectively collected data from patients in the University of North Carolina EoE Registry. Patients were categorized with histologically active (≥ 15 eosinophils per high-power field [eos/hpf]) or inactive (< 15 eos/hpf) disease. Dysphagia severity was measured with a Likert scale. QoL was measured with 36-Item Short Form (SF-36), compared between active and inactive groups, and assessed longitudinally. Results: Of 147 EoE cases, those with inactive disease (n = 56) reported less dysphagia severity (3.2 vs. 1.9; p = 0.003) and had lower endoscopic severity (3.8 vs. 1.0; p < 0.001) than those with active disease (n = 91). While SF-36 scores did not differ between active and inactive status, lower mental component scores (MCS) were seen in patients treated with empiric dietary elimination (44.9 vs. 50.8; p = 0.005). Dysphagia severity was negatively correlated with both physical component score (PCS) (r = −0.33; p < 0.001) and MCS (r = −0.18; p = 0.03). Despite more cases achieving histologic response over time, SF-36 scores did not improve on either raw or adjusted analyses. Conclusion: QoL measured by SF-36 in EoE was similar regardless of histologic disease activity and was in the range of population averages. General QoL metrics like the SF-36 do not appear to have substantial utility in EoE. [ABSTRACT FROM AUTHOR]

The study aimed to assess the level of inflammatory biomarkers related to eosinophilia: interleukins 5 (IL-5) and 13 (IL-13), eotaxin 3, major basic protein (MBP) and transforming growth factor β1 (TGF-β1) in patients with dysphagia and Schatzki ring (SR), as well as the characteristics of this group of patients in terms of the features differentiating gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE). We analyzed 42 patients with dysphagia, each of whom underwent panendoscopy with an assessment of the occurrence of SR, retrospectively assessed EoE Endoscopic Reference Score (EREFS) total, inflammatory and fibrostenotic and serum concentrations of IL-5 and 13, TGF-β1, eotaxin 3 and MBP. All of them completed a symptom and comorbid questionnaire. Patients diagnosed with SR constituted the SR group (n ​= ​8), the rest – the non-SR group. The quantification of the biomarkers was performed by enzyme immunoassay (ELISA). In the data analysis, p ​≤ ​0.05 was considered statistically significant. We demonstrated a significant increase in terms of exceeding the reference values of TGF-β1 (37.5% vs 8.8%) and MBP (75% vs 35.3%) in patients with SR compared to the non-SR group (qualitative analysis). There was also a statistically significant increase in the concentration of each of the determined biomarkers (quantitative analysis) in the SR group. The increase in TGF-β1 and MBP concentrations indicates the inflammatory and probably fibrostenotic pathogenesis of SR. Obtained results do not allow for an unequivocal classification of SR as a complication typical only for GERD or EoE. [ABSTRACT FROM AUTHOR]

Background: A proportion of patients with active eosinophilic esophagitis (EoE) have a normal-appearing esophagus on esophagogastroduodenoscopy (EGD). We aimed to determine the associations between the baseline clinical features and the endoscopically normal esophagus in EoE, as well as time trends in reporting.Methods: In this retrospective study of active EoE cases from 2002 - 2018, patients with and without esophageal endoscopic abnormalities were compared. Multivariable logistic regression identified the independent predictors of a normal EGD. The proportion of patients with a normal EGD was determined per year, and before and after the introduction of the first EoE guidelines and the EoE Endoscopic Reference Score (EREFS).Results: Of 878 EoE patients, 101 (11.5 %) had an endoscopically normal esophagus; they were younger (8.3 vs. 25.4 years), had shorter median symptom duration before diagnosis (2.8 vs. 5.0 years), were less likely to have dysphagia (40 % vs. 76 %) or food impaction (8 % vs. 33 %), and more likely to have abdominal pain (37 % vs. 19 %) (P < 0.01 for all). On multivariable logistic regression, independent predictors of a normal esophagus were younger age (odds ratio [OR] 0.96, 95 % confidence interval [CI] 0.94 - 0.98), abdominal pain (OR 2.03, 95 %CI 1.13 - 3.67), and lack of dysphagia (OR 0.49, 95 %CI 0.26 - 0.93). The proportion of patients with a normal esophagus decreased from 21 % before the first EoE guidelines to 7 % (P < 0.01) after introduction of the EREFS.Conclusions: An endoscopically normal esophagus is seen in ~10 % of active EoE patients and should not preclude biopsies; younger age, abdominal pain, and lack of dysphagia are independent predictors. The proportion of normal EGDs decreased over time, suggesting improved recognition of endoscopic findings. [ABSTRACT FROM AUTHOR]

Background: Eosinophilic esophagitis (EoE) is thought to be an atopic disorder causing dysphagia. HIV patients have dysphagia from both common (reflux esophagitis) and uncommon causes (idiopathic esophageal ulceration). Only a single case report about the occurrence of EoE in an HIV patient exists in literature. Aim: The aim of this study was to determine if HIV and EoE occur concurrently using a large inpatient database. Methods: Data on hospital admissions of all HIV adult patients were extracted from the 2002–2014 National Inpatient Sample. Comorbidities and outcomes of interest were defined by querying all diagnostic and procedural fields for the corresponding ICD-9 codes. Univariable and multivariable logistic regression analysis was performed to assess the association between HIV and EoE. Similarly, we assessed the relation between HIV and eosinophilic gastroenteritis (EGE). Results: The total population comprised of 101,137,145 patients, of which 231,691 (0.229%) have HIV and 5038 (0.004%) have EoE. HIV patients were younger (45.2 vs 48 years old and more likely to be male (62.2% vs 41.5%) and African American (53.9% vs 14.2%) compared to non-HIV patients (P < 0.001 for all). After adjusting for potential cofounding factors, HIV patients had a statistically significant higher rate of EoE (Odds Ratio 2.108, with 95% confidence interval 1.268-3.506, P = 0.004) compared to the non-HIV group. On the other hand, HIV was not associated with increased risk of EGE (Odds Ratio 0.78, 95% confidence interval 0.109-5.557, P = 0.804). Conclusion: Patients with HIV are twice as likely to have EoE compared to those without HIV. Evaluation of dysphagia in HIV patients should include assessment for EoE, especially when empiric antifungal therapy for candida esophagitis does not improve clinical symptoms.

Objectives: The rate of eosinophilic esophagitis (EoE) diagnosis is increasing. This study aims to determine the incidence of EoE in the pediatric population residing in the southwestern Madrid and to analyze whether absolute monthly pollen counts, modified or not by the principal atmospheric pollutants, are associated with it. Methods: A cross‐sectional study on prospectively recruited patients was designed to calculate the incidence of EoE in children aged under 15 years who were diagnosed between September 2014 and August 2016 in twelve hospitals. We collected demographic and symptoms data, date of onset of symptoms, date of medical consultation, and date of endoscopic diagnosis of each included patient. Relative risk estimation was performed to assess the association between the incidence of diagnosis and monthly pollen counts and levels of atmospheric pollutants. All these models were adjusted for the number of total patients that underwent endoscopy at first time. Results: One hundred forty‐eight patients were included. The most frequent symptoms were abdominal pain [42.57%], dysphagia [42.57%], and impaction [39%–86%]. The median overall monthly incidence was 1.13 [interquartile rank: 0.97–1.43] cases/100,000 children, and the annual mean was 15.2. The overall analysis of the relationship between incidence and absolute monthly counts, corrected for the number of first‐time endoscopies performed, revealed no statistically significant association with pollen and air pollutants. There was a higher frequency of diagnosis during the pollination period of Cupressaceae [relative risk 1.647; 95% CI (1.192–2.276) p <.002] and during February and November (relative risk 1.67; p <.01). Conclusions: This study confirms the high incidence of eosinophilic esophagitis and also suggests a period of higher incidence of diagnosis in the months of February and November as well as in the period of high pollination of Cupressaceae.

Background: Endoscopic ultrasonography (EUS) and high-resolution manometry (HRM) can be used in the evaluation of eosinophilic esophagitis (EoE) for frequent symptoms such as dysphagia. However, the role of these examinations is not clear. Aims: The aim of this study was to objectively evaluate the subjective symptoms of EoE patients with EUS and HRM. Methods: Patients who had endoscopic findings indicative of EoE and matched the number of eosinophil infiltrates used as diagnostic criteria were recruited between September 2018 and August 2019. Evaluable subjects underwent EUS and HRM and completed the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. The esophageal wall thickness (evaluated with EUS) and HRM parameters between patients with and without symptoms were retrospectively compared. Symptomatic patients were re-examined using EUS and HRM 6 months after treatment. Results: A total of 35 patients (29 males, median age of 49 years) were divided into symptomatic (20 patients) and asymptomatic groups (15 patients). The esophageal wall was thicker, and the distal contractile integral (DCI) values were higher in the symptomatic group (P < 0.001). In addition, DCI values were positively correlated with esophageal wall thickness. After treatment, the GSRS scores showed an improving trend for each item. Esophageal wall thickness and DCI values were significantly decreased (Ps < 0.001). Conclusions: Esophageal wall thickening and increased esophageal body pressure may be involved in subjective symptoms. In addition, treatment may reduce esophageal thickness and pressure along with improvement of subjective symptoms. [ABSTRACT FROM AUTHOR]

Background: Eosinophilic esophagitis (EoE) is an immune-mediated clinicopathological condition characterized by esophageal infiltration with eosinophils resulting in chronic inflammation and stricture. Summary: The recent increase in the incidence of EoE and the characteristic presentation of symptoms with difficulty swallowing and food bolus impaction has raised key concerns of clinicians as well as researchers. EoE often presents with dysphagia, food impaction, nausea, regurgitation or vomiting, and decreased appetite. It is more common in males, affecting both adults and children. The causative manner of this condition is complex and multifactorial. Throughout recent years, researchers have made a significant contribution to understanding the pathogenesis of EoE, genetic background, natural history, work on allergy, and standardization in the evaluation of disease activity. There is relatively high prevalence of EoE among the population, emphasizing the importance of this disease. Key messages: Esophageal involvement with eosinophils may be manifested as isolated or with coexisting conditions and should be taken into consideration in the differential diagnosis. This study aimed to provide gastroenterologists with novel insights into the evaluation of esophageal involvement with eosinophils and to pay special attention to the etiological factors, coexisting clinical diseases, and complications.

Esophageal subepithelial activity (ESEA) is an important determinant of disease severity and complications in eosinophilic esophagitis (EoE). Inflammation and fibrosis of the lamina propria and muscularis propria result in esophageal dysfunction and stricture formation that are clinically manifest by symptoms of dysphagia and food impaction as well as the need for esophageal dilation. Esophageal biopsies that are limited to the evaluation of the esophageal epithelium are an inadequate means to assess overall, clinical disease severity in EoE. Instruments for the assessment of subepithelial activity in EoE are both limited and/or underutilized and thus represent an important unmet clinical need. Studies using endoscopic features, endoscopic ultrasonography, and barium esophagography have demonstrated improvement in ESEA parameters with topical steroid therapy. Impedance planimetry is being evaluated as an objective and quantifiable measure of esophageal distensibility that is a consequence of ESEA. In conjunction with symptom and histologic assessment, evaluation of ESEA provides a more complete evaluation of disease activity in EoE that will enhance clinical care as well as provide insights into the strengths and limitations of therapeutic interventions.

Eosinophilic esophagitis (EoE) is a chronic disease with non-specific symptoms, among which dysphagia is a prevailing one. The observed increase of EoE rate, its chronic and recurrent character, as well as invasive follow-up examination (periodical panendoscopy with specimen collection for histopathology), compel optimization of both the diagnostics algorithm and disease monitoring through searching for new, unique methods and tools so far not applied, including high-resolution manometry (HRM). Mentioned investigations result from advances in comprehension of disease pathogenesis, in which it is suggested that development of a chronic inflammatory reaction of the esophageal wall may lead to consecutive fibrosis and motility disorders. In research published to date one manometric pattern characteristic for EoE was not obtained, whereas the obtained inconsistent and at times contradictory results do not correlate either with symptoms exacerbation or endoscopic scan. Numerous constraints of discussed studies as well as current knowledge in disease etiopathology and esophagus biomechanics prompt further investigation of HRM significance in diagnostics and therapy monitoring of patients with EoE.

Eosinophilic esophagitis (EoE) represents a chronic, local immune‐mediated esophageal disease, characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil‐predominant inflammation. Other systemic and local causes of esophageal eosinophilia should be excluded. Clinical manifestations or pathologic data should not be interpreted in isolation. EoE was first described as a distinct disease entity in 1993. Most patients are diagnosed with underlying food allergies. The first diagnostic and therapeutic guidelines were published in 2007 with a first update in 2011. In 2017, new international guidelines were published based on the GRADE methodology. These guidelines provide, among many other topics, insights on the role of proton pump inhibitor‐responsive esophageal eosinophilia. Over the last two decades, considerable progress was made by stakeholders regarding the understanding of EoE's pathogenesis, genetic background, natural history, allergy workup, standardization of assessment of disease activity, evaluation of minimally invasive diagnostic tools, and new therapeutic approaches. This brief review provides further insights into latest diagnostic and therapeutic advances.

Acute herpes simplex esophagitis (HSE) is common in immunocompromised patients. Eosinophilic esophagitis (EoE) is characterized by immune-mediated eosinophil-predominant esophageal inflammation. We report a patient with human immunodeficiency virus infection who presented with dysphagia and odynophagia and was found to have HSE and EoE. The combination of these two relatively rare conditions suggests possible predisposition. [ABSTRACT FROM AUTHOR]

Background: Eosinophilic esophagitis (EoE) is the most common cause of dysphagia and esophageal food impaction (EFI) in the USA, Western Europe, and Australia. In Mexico, the uncomplicated form of this disease is infrequent, and prevalence in patients with EFI is unknown.Aims: To determine the prevalence and causes of EFI, endoscopic and therapeutic aspects, and establish the prevalence of biopsy-proven EoE in patients with EFI.Methods: Diagnostic upper gastrointestinal endoscopy reports from January 2011 to December 2016 were retrospectively reviewed. Patients with therapeutic procedures, gastrointestinal hemorrhage, or non-food foreign body impaction were excluded. The number of patients with EFI was determined. Additionally, patients with esophageal biopsy were retained for EoE prevalence calculation. The diagnosis of EoE was defined with the presence of eosinophil infiltration count ≥ 15/high-power field with or without typical endoscopic abnormalities.Results: A total of 4700 reports of the same number of patients were selected; 2209 were males (47%) with a mean age of 57.6 ± 12.3 years (range 14-93). We identified 36 patients with EFI (0.76, 95% CI 0.51-1.01), 16 males (44.4%) with a mean age of 54.9 ± 19.7 (range 22-92). Esophageal biopsies were obtained in 17/36 (47.2%) cases. The diagnosis of EoE was confirmed in 2 patients (11.7%). Peptic stenosis was the most frequent cause of EFI.Conclusions: EoE is an infrequent cause of EFI in the Mexican population (11.7%). EoE had the lowest prevalence compared to that reported in Caucasian populations. The prevalence of EFI was also low. [ABSTRACT FROM AUTHOR]

Introduction: The prevalence of eosinophilic esophagitis (EoE), a chronic, immune-mediated, clinicopathologic, inflammatory disorder, has been well described in the pediatric and adult Caucasian population but not as well studied in the Hispanic population. The major aims of this study are to determine the prevalence and gene expression profile of EoE in these populations.Methods: This is a retrospective cohort study of patients from two institutions predominantly serving a Hispanic population. Patients included at Los Angeles County Hospital (LACH) had an esophagogastroduodenoscopy (EGD) and esophageal biopsies performed for evaluation of dysphagia and/or food impaction, while patients included from the University Hospital Medical Center of El Paso (UHMCEP) had an EGD and esophageal biopsies performed for any appropriate clinical indication. Gene expression analysis which has been shown to accurately diagnose EOE in Caucasians was performed for 9 patients at UHMCEP to determine its accuracy in Hispanics.Results: At LACH, 234 patients were included in the study of whom 155 (66.3%) were Hispanic and 22 (9.4%) were Caucasian. 3.2% of the Hispanic patients and 9.1% of the Caucasian patients were diagnosed with EOE with threefold difference. At UHMCEP 1700 patients were included of whom 1350 (79.4%) were Hispanic and 179 (10.5%) were Caucasian. 0.96% of the Hispanic patients and 7.26% of the Caucasian patients were diagnosed with EOE with a sevenfold difference. Gene expression accurately diagnosed EOE in a small number of both Hispanics and Caucasians who underwent analysis.Conclusions: Hispanic patients at LAC and UMHCEP had a significantly lower prevalence of EOE as compared to Caucasians at these two institutions and a lower prevalence as compared to Caucasians with EOE previously reported in the literature. Gene expression analysis, which has previously been shown to accurately diagnose EOE in Caucasian patients, accurately diagnosed EOE in a small sample of this Hispanic population. Based on this similar gene expression, other factors such as environmental, ethnic, and cultural causes should be investigated to explain the markedly lower prevalence of EOE in Hispanics.

Background: Esophageal granular cell tumor (eGCT) is a rare, usually benign, neoplasm of neuroectodermic origin. Eosinophilic esophagitis (EoE) is a relatively uncommon, immune-mediated, chronic disease. Both diseases commonly present with dysphagia. One case has been reported of simultaneous occurrence of both diseases.Aims: To determine the association between diseases.Methods: The present study was an IRB-approved, retrospective review of esophagogastroduodenoscopies (EGDs) with esophageal biopsies from two large hospitals, 1999-2014.Results: Among 29,235 EGDs with esophageal biopsies for 16 years (167,434 total EGDs), 16 patients had pathologically diagnosed eGCT, and 1225 patients had pathologically diagnosed EoE. Five (31%) of 16 patients with eGCT had concomitant EoE (p = 0.001, OR 10.43, 95% ORCI 3.16-32.44, Fisher's exact test). Patients with simultaneous eGCT and EoE were young (mean age = 33.6 ± 12.9 years). Three were female. Dysphagia was presenting symptom in 4 (80%) of patients. Three had asthma. All five patients had > 20 eosinophils/hpf in esophageal biopsy specimens. Three patients had endoscopic esophageal abnormalities suggesting EoE. Four patients were treated with a PPI (before and after diagnosis of EoE), and 2 patients underwent six-food-elimination diet with partial symptomatic improvement. The eGCTs averaged 13.4 ± 4.2 mm in maximal diameter and were located in upper-2, middle-2, and lower esophagus-2 (1 patient had 2 eGCTs). eGCTs were endoscopically resected-3 patients, and monitored-2 patients. Surveillance endoscopies revealed no recurrence or growth of eGCTs after resection (mean follow-up = 4.6 years).Conclusions: This novel report of 5 patients with simultaneous EoE and eGCT adds to one, previously published case and suggests these two diseases are associated, and have a common pathophysiologic link, despite apparently different pathogenesis. Large, prospective, endoscopic and pathologic studies are warranted to further investigate this association. [ABSTRACT FROM AUTHOR]

Background Limited data describe the long-term efficacy of dietary elimination in eosinophilic oesophagitis (EoE). Aim To assess the long-term outcomes of food elimination diets for treatment of adults with EoE. Methods We conducted a retrospective cohort study at our centre analysing all EoE patients receiving a food elimination diet without concomitant steroids. Baseline data were abstracted using standardised collection forms. Follow-up data from a mean 24.9-month period were collected for patients with a histological response to a food elimination diet during and after food reintroduction. The main outcomes were symptomatic, endoscopic and histological responses. Results Of 52 patients, 18 received a 6-food food elimination diet, 32 received targeted diet, and two received a 6-food food elimination diet with targeted elimination. There were 21 (40%) patients with an initial histological response. Responders reported less dysphagia after treatment (95% baseline vs 11%; P = .001) and at the end of follow-up (95% baseline vs 33%; P = .008). Significant and durable endoscopic improvements were recorded at the same time points: Endoscopic reference score: 3.2 vs 0.7; P = .001; and 3.2 vs 1.7; P = .06. Histological findings improved after the most restrictive diet in responders (49.8 vs 4.1 eosinophils per high-power field; P = .001) and remained suppressed in the 10 initial responders maintaining compliance at the end of follow-up (5.2 eosinophils per high-power field). Conclusions Among EoE patients responding to a food elimination diet and remaining adherent, maintenance dietary therapy produced durable long-term symptomatic, endoscopic and histological disease control. These long-term data confirm that a food elimination diet is an effective maintenance treatment option in select adults with EoE. [ABSTRACT FROM AUTHOR]

Background While symptom scores have been developed to evaluate dysphagia in eosinophilic oesophagitis (EoE), their complexity may limit clinical use. Aim To evaluate a visual analogue scale ( VAS) and a 10-point Likert scale ( LS) for assessment of dysphagia severity before and after EoE treatment. Methods We conducted a prospective cohort study enrolling consecutive adults undergoing out-patient endoscopy. Incident cases of EoE were diagnosed per consensus guidelines. At diagnosis and after 8 weeks of treatment, symptoms were measured using the VAS, LS and the Mayo Dysphagia Questionnaire ( MDQ). The percentage change in scores before and after treatment were compared overall, in treatment responders (<15 eos/hpf) and non-responders, and in patients without baseline dilation . Results In 51 EoE cases, the median VAS decreased from 3.6 at baseline to 1.4 post-treatment (71% decrease), the LS decreased from 6 to 2 (67%) and the MDQ decreased from 20 to 10 (49%). The VAS correlated with both the LS ( R = 0.77; P < 0.0001) and MDQ ( R = 0.46, P = 0.001). After stratification by histological response, the LS decreased 70% in responders vs. 13% in non-responders ( P = 0.02). In patients who did not receive baseline dilation, both the VAS and LS decreased significantly more in the histological responders. Conclusions Both the VAS and LS were responsive to successful treatment as measured by histologic improvement. Because the VAS and LS are simple to administer and are responsive to treatment, they can provide an efficient and objective method for assessing dysphagia severity in EoE in clinical practice.

Background and study aims No specific endoscopic signs for diagnosing eosinophilic esophagitis (EoE) have been described and very few studies have reported endoscopic signs for lymphocytic esophagitis (LyE). This study aimed to assess the utility of narrow-band imaging magnifying endoscopy (NBI-ME) in predicting EoE/LyE diagnosis before histopathological assessment. Patients and methods Adult patients with dysphagia and/or food impaction who underwent esophagogastroduodenoscopy followed by NBI-ME and biopsies were included. Three previously reported NBI-ME signs were studied: beige mucosa, dot-shaped intra-epithelial papillary capillary loop (IPCL), and absent cyan vessels. These signs were compared with the histological diagnosis, and studied in patients with and without EoE or LyE. A predictive model containing the NBI-ME signs was analyzed, based on area under the curve (AUC). Results A total of 137 patients were enrolled. Based on histology 26 were diagnosed with EoE, 26 with LyE, and 85 were control patients with neither diagnosis. Significantly more EoE/LyE patients than control patients showed the NBI signs (P  < 0.001 for all three signs). Absent cyan vessels had the highest accuracy for differentiation (sensitivity 88 %, specificity 92 %). A combination of age, dot IPCLs, and absent cyan vessels was highly predictive of EoE/LyE, with an AUC of 0.952. Conclusions Three NBI-ME signs were found in the majority of patients with EoE/LyE and unlikely to be observed in controls. A combination of two NBI-ME signs and younger age had a higher degree of accuracy. This supports the claim that NBI-ME could be a reliable diagnostic modality for EoE/LyE predictors.

Background: Esophageal eosinophilia is classified as either eosinophilic esophagitis (EoE) or proton-pump inhibitor-responsive esophageal eosinophilia (PPI-REE), depending on the response to PPI treatment. The aim of this study was to compare the clinical, endoscopic, and histopathological findings of EoE and PPI-REE in Japanese patients. In addition, the characteristics of these cases were compared with those of reflux esophagitis (RE) cases.Methods: Eleven patients diagnosed with EoE, 16 with PPI-REE, and 39 with RE, who were all consecutively examined from 2005 to 2015 at Shimane University Hospital, were enrolled. Clinical, endoscopic, and histopathological esophageal findings in these groups were retrospectively examined and compared.Results: The differences in the clinical characteristics of EoE and PPI-REE were not remarkable, though patients with EoE and PPI-REE were younger, presented a higher prevalence of allergic comorbidities, and complained of symptoms of dysphagia more frequently than those with RE. The only noteworthy differences between EoE and PPI-REE were more frequent reports of asthma (36.4 vs. 2.6 %) and food allergy (27.3 vs. 0 %) by patients with EoE (P < 0.05, P < 0.05, respectively). Endoscopic findings in patients with EoE and PPI-REE were similar, with the presence of esophageal erosions in a small percentage of PPI-REE cases being the only difference. There were no histopathological differences between EoE and PPI-REE.Conclusions: Comparisons of clinical, endoscopic, and histopathological findings between EoE and PPI-REE showed that these two types have similar characteristics, though EoE patients showed a higher atopic background. Predicting PPI responsiveness in cases with esophageal eosinophilia is difficult and requires further investigation. [ABSTRACT FROM AUTHOR]

Background: Because eosinophilic esophagitis (EoE) causes dysphagia, esophageal narrowing, and strictures, it could result in low body mass index (BMI), but there are few data assessing this.Aim: To determine whether EoE is associated with decreased BMI.Methods: We conducted a prospective study at the University of North Carolina from 2009 to 2013 enrolling consecutive adults undergoing outpatient EGD. BMI and endoscopic findings were recorded. Incident cases of EoE were diagnosed per consensus guidelines. Controls had either reflux or dysphagia, but not EoE. BMI was compared between cases and controls and by endoscopic features.Results: Of 120 EoE cases and 297 controls analyzed, the median BMI was lower in EoE cases (25 vs. 28 kg/m2, p = 0.002). BMI did not differ by stricture presence (26 vs. 26 kg/m2, p = 0.05) or by performance of dilation (26 vs. 27 kg/m2 for undilated; p = 0.16). However, BMI was lower in patients with narrow caliber esophagus (24 vs. 27 kg/m2, p < 0.001). EoE patients with narrow caliber esophagus also had decreased BMI compared to controls with narrow caliber esophagi (24 vs. 27 kg/m2, p = 0.001). On linear regression after adjustment for age, race, and gender, narrowing decreased BMI by 2.3 kg/m2 [95% CI -4.1, -0.6].Conclusions: BMI is lower in EoE cases compared to controls, and esophageal narrowing, but not focal stricture, is associated with a lower BMI in patients with EoE. Weight loss or low BMI in a patient suspected of having EoE should raise concern for esophageal remodeling causing narrow caliber esophagus. [ABSTRACT FROM AUTHOR]

Eosinophilic esophagitis (EoE) is a rare disease of the esophagus that is characterized by eosinophilic infiltrate within the esophageal mucosa resulting in chronic inflammation and stenosis. It typically presents with symptoms of esophageal dysfunction with dysphagia and food impaction being the most common presenting complaints. Herein we describe a rare case presentation of a young patient with spontaneous esophageal perforation in the setting of undiagnosed EoE. We suggest that the placement of a covered esophageal stent can provide full closure of the perforation and restoration of the integrity of the GI tract without the need for more invasive open repair. The patient had a short recovery time with no reported postoperative complications upon 30 months follow up. We believe that it's important to consider and rule out EoE in patients with a history of dysphagia and esophageal perforation. [ABSTRACT FROM AUTHOR]

Background and Aims: Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder with increasing prevalence. However, epidemiologic data have mostly been acquired from small studies. We sought to describe the epidemiology of EoE in the USA, utilizing a large database.Methods: We queried a commercial database (Explorys Inc, Cleveland, OH, USA), an aggregate of electronic health record data from 26 major integrated US healthcare systems from 1999 to July 2015. We identified an aggregated patient cohort of eligible patients with EoE and a history of proton-pump inhibitor use between July 2010 and July 2015, based on Systematized Nomenclature of Medicine-Clinical Terms. We calculated the prevalence of EoE among different patient groups.Results: Of the 30,301,440 individuals in the database, we identified 7840 patients with EoE with an overall prevalence of 25.9/100,000 persons. Prevalence was higher in males than females [odds ratio (OR) 2.00; 95 % CI 1.92-2.10, p < 0.0001], Caucasians versus African-Americans and Asians (OR 2.00; 95 % CI 1.86-2.14, p < 0.0001), and adults (18-65 years) versus elderly (>65 years) and children (<18 years) (OR 1.63; 95 % CI 1.54-1.71, p < 0.0001). Compared with controls (individuals in database without EoE), individuals with EoE were more likely to have other gastrointestinal diagnoses such as dysphagia and at least one allergic condition.Conclusions: In this large study, we found that the estimated prevalence of EoE in the USA is 25.9/100,000, which is at the lower end of prevalence rates reported in the USA and other industrial countries. We confirmed that EoE has a strong association with allergic and gastrointestinal diagnoses. [ABSTRACT FROM AUTHOR]

Background: Lymphocytic esophagitis (LyE) is a recently described clinicopathological condition, but little is known about its features and clinical associations.Aim: The aim of this study was to characterize patients with LyE, compare them to non-LyE controls, and identify risk factors.Methods: We conducted a retrospective study of all patients ≥18 years old who underwent upper endoscopy with esophageal biopsy between January 1, 2000, and June 1, 2012. Archived pathology slides were re-reviewed, and LyE was diagnosed if there was lymphocyte-predominant esophageal inflammation with no eosinophils or granulocytes. Three non-LyE controls groups were also defined: reflux, eosinophilic esophagitis (EoE), and normal. Clinical data were extracted from electronic medical records, and LyE cases were compared to non-LyE controls.Results: Twenty-seven adults were diagnosed with LyE, and the majority were female (63 %). The most common symptom was dysphagia (70 %). Fifty-two percentage had a prior or current diagnosis of reflux. Endoscopic findings included strictures (37 %), erosive esophagitis (33 %), rings (26 %), and hiatal hernia (26 %); 33 % of patients required dilation. After histology re-review, 78 % of LyE patients were found to have more than 20 lymphs/hpf. In comparison with the normal, reflux and EoE controls, patients with LyE tended to be nonwhite (p < 0.01), were more commonly tobacco users (p = 0.02) and less likely to have seasonal allergies (p = 0.02).Conclusion: LyE commonly presents with dysphagia due to esophageal strictures which require dilation. Smoking was associated with LyE, whereas atopy was not. LyE should be considered as a diagnostic possibility in patients with these characteristics undergoing upper endoscopy. [ABSTRACT FROM AUTHOR]

Background Little is known about the relationship between proton pump inhibitor-responsive oesophageal eosinophilia ( PPI- REE), eosinophilic esophagitis (EoE) and gastro-oesophageal reflux disease ( GERD). Aim To compare high resolution manometry features and symptom profiles of patients with EoE, PPI- REE and GERD. Methods Consecutive patients diagnosed with EoE or PPI- REE according to international criteria (presence of at least one typical symptom of oesophageal dysfunction; at least 15 eosinophils per high-power field at mid/proximal oesophagus, persistence or resolution of eosinophils after an 8-week PPI trial), and a group of patients with proven GERD and oesophageal eosinophilia, prospectively completed the GerdQ questionnaire and underwent high resolution manometry. Results Thirty-five patients with EoE, 17 with PPI- REE and 27 with GERD were enrolled. When compared to GERD, both EoE and PPI- REE had higher rates of dysphagia (15% vs. 94% vs. 88%, P < 0.0001), patients with EoE reported heartburn and regurgitation less frequently (26% vs. 85%, and 17% vs. 74%, respectively; P < 0.001 for each and had lower GerdQ score [1 (0-6) vs. 8 (6-12), P < 0.001] than GERD patients. There was no significant difference comparing PPI-REE and GERD patients. Patients with PPI-REE had a higher prevalence of erosive oesophagitis than patients with EoE (35% vs. 9%, P = 0.04), which was similar to that of GERD (48%, P = 0.54). Patients with EoE had a lower frequency of high resolution manometry features associated with GERD than patients with PPI-REE. There was no significant difference between PPI-REE and GERD patients. Conclusion GERD, as assessed by GerdQ and high resolution manometry is common in patients with PPI-REE, which may share similar pathogenic mechanisms. [ABSTRACT FROM AUTHOR]

Objective To investigate the efficacy and safety of two different budesonide formulations (effervescent tablet for orodispersible use (BET) and viscous suspension (BVS)) with different daily dosages for short-term treatment of eosinophilic oesophagitis (EoE). Design Adults with active EoE (n=76) randomly received 14 days' treatment with either BET 2x1 mg/day (BET1, n=19) or BET 2x2 mg/day (BET2, n=19), or BVS 2x5 mL (0.4 mg/mL)/day (BVS, n=19) or placebo (n=19) in a double-blind, double-dummy fashion, with a 2-week follow-up. Primary end point was histological remission (mean of <16 eosinophils/mm² hpf ). Secondary end points included endoscopy score, dysphagia score, drug safety and patient's preference for drug formulation. Results Histological remission occurred in 100%, 94.7% and 94.7% of budesonide (BET1, BET2, BVS, respectively) and in 0% of placebo recipients (p<0.0001). The improvement in total endoscopic intensity score was significantly higher in the three budesonide groups compared with placebo. Dysphagia improved in all groups at the end of treatment; however, improvement of dysphagia persisted only in those treated with BET1 (p=0.0196 vs placebo). There were no serious adverse events. Local fungal infection (stained fungi) occurred in two patients of each budesonide group (10.5%). The effervescent tablet was preferred by 80% of patients. Conclusions BET or BVS was highly effective and safe for short-term treatment of EoE. The 1 mg (twice daily) dosage was equally effective as the 2 mg twice daily dosage. The majority of patients preferred the effervescent tablet formulation. [ABSTRACT FROM AUTHOR]

Eosinophilic esophagitis ( EoE) is a chronic, immune-mediated disease resulting in symptoms of esophageal dysmotility. Abnormalities include dysphagia, food impaction and reflux. Although men appear to comprise a majority of the EoE population, few studies have directly assessed gender-associated clinical differences. The aim of this study is to identify the effect of gender on the initial clinical presentation of adult-onset EoE patients. We reviewed our electronic medical record database from January 2008 to December 2011 for adults diagnosed with EoE per the 2011 updated consensus guidelines. Patient demographics, presenting symptoms, endoscopy findings and complications were recorded. Proportions were compared using chi-squared analysis, and means were compared using the Student's t-test. A total of 162 patients met the inclusion criteria and 71 (44%) were women. Women were more likely to report chest pain ( P = 0.03) and heartburn ( P = 0.06), whereas men more commonly reported dysphagia ( P = 0.04) and a history of food impaction ( P = 0.05). Endoscopic findings were similar between groups. No patients suffered esophageal perforations. These data suggest that men report more fibrostenotic symptoms and women report more inflammatory symptoms at the time of diagnosis. There was no difference in endoscopic findings between genders. This is one of the only reviews comparing differences in clinical presentation, endoscopic findings and complications between gender for EoE. The current recommended guidelines state that any patient with symptoms of esophageal dysfunction should be biopsied for EoE. Our findings support biopsying patients with typical and atypical symptoms of dysmotility including heartburn and chest pain. [ABSTRACT FROM AUTHOR]

Background/Aims: Proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE) is a newly recognized form of eosinophilic esophagitis (EoE) that responds to PPI therapy. It remains unclear whether PPI-REE represents a subphenotype of gastroesophageal reflux disease, a subphenotype of EoE, or its own distinct entity. The aim was to evaluate the clinicopathologic features of PPI-REE. Methods: Six patients were diagnosed with PPI-REE based on symptoms, endoscopic abnormalities, esophageal eosinophilia with ≥15 eosinophils/high-power field, and a response to PPI treatment. Symptoms and endoscopic and pathological findings were evaluated. Results: The median follow-up duration was 12 months. Presenting symptoms included dysphagia, heartburn, chest pain, foreign body sensation, acid reflux, and sore throat. All patients had typical endoscopic findings of EoE such as esophageal rings, linear furrows, nodularity, and whitish plaques. Three patients had a concomitant allergic disorder, and one had reflux esophagitis. Four patients exhibited elevated serum IgE, and five had positive skin prick tests. All patients experienced symptomatic resolution within 4 weeks and histologic resolution within 8 weeks after starting PPI therapy. There was no symptomatic recurrence. Conclusions: PPI therapy induced rapid resolution of symptoms and eosinophil counts in patients with PPI-REE. Large-scale studies with long-term follow-up are warranted. [ABSTRACT FROM AUTHOR]

Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated disease, with dysphagia as 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 Dysphagia Scale (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 Dysphagia and 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-36 scores. 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. [ABSTRACT FROM AUTHOR]

Background Eosinophilic esophagitis ( EoE) is a newly recognised condition that is apparently increasing in prevalence, and the aetiology is poorly understood. The role of aeroallergens in EoE is controversial, given the success of dietary therapy. Massive aeroallergen exposure leading to food bolus obstruction events ( FBOE) has been described, and the diagnosis of EoE by esophageal biopsy noted to be more common in the pollen season according to previous case series. Aim To determine if a seasonal variation and a geographical variation occurred in EoE presenting as FBOE in adults, and to track the prevalence of FBOE and EoE over time. Method A retrospective case-control study analysis was performed from January 2002 to January 2012 to identify all FBOE in adults presenting to five tertiary hospitals in Melbourne, Australia. Endoscopy, histopathological reports, case notes and blood tests were examined, and postcodes recorded. Records of pollen counts were obtained. Cases were defined according to esophageal biopsy and grouped based on month of diagnosis. All other causes of FBOE served as controls. Results One thousand, one hundred and thirty-two FBOE were identified. Biopsies were only performed in 278 of these cases, and 85 patients were found to have EoE after biopsy. Patients with EoE were younger (mean age 38 years, range 18-72) compared with those with alternative diagnosis (mean age 64.4 range 22-92), more likely to be male ( M : F = 4:1 compared with 1.68:1 ) and had a higher eosinophil count in venous blood. Overall no seasonality was demonstrated in FBOE secondary to any diagnosis, although the six cases of recurrent FBOE secondary to EoE mainly occurred in the grass pollen season in subsequent years. FBOE cases were evenly distributed throughout metropolitan Melbourne irrespective of population density. EoE as a percentage of FBOE increased over time. Conclusion Seasonal aeroallergens may be important for a subgroup of patients with EoE presenting as recurrent FBOE. Esophageal biopsies are performed in a minority of patients, representing a significant departure from ideal management and contributing to recurrent unnecessary FBOE. EoE is an increasingly important cause of FBOE. [ABSTRACT FROM AUTHOR]

Background and Aims: Prior to the consensus guideline conference in 2007, eosinophilic esophagitis (EoE) was uncommon dominated by the fibrostenotic phenotype, but over the past decade has become a common cause of dysphagia with more inflammatory phenotypes diagnosed. We assessed the impact of guideline definitions on the characteristics of EoE phenotypes over the past 26 years at our institution. Methods: We reviewed the electronic health record of 75 consecutive patients meeting guideline definition EoE from 1/1988 to 5/2014. We separated groups based on 5-year intervals of diagnosis and phenotype. For continuous data, results were summarized as mean difference and standard deviation with 95 % confidence intervals. Results: Five groups based on 5-year intervals of diagnosis were identified: group 1-1988-1993 ( n = 7), group 2-1994-1999 ( n = 7), group 3-2000-2005 ( n = 4), group 4-2006-2011 ( n = 35), and group 5-2012-2014 ( n = 22). Prior to 2000, all patients were diagnosed with fibrostenotic EoE. After the initial 2007 guideline conference, inflammatory EoE has predominated with only one-third diagnosed with fibrostenotic EoE. Prior to 2011, only two were diagnosed with PPI-REE. In the last 3 years, 8 out of 22 patients (32 %) had PPI-REE. Overall, 8 out of 10 (80 %) PPI-REE were the inflammatory phenotype. When comparing pre- ( n = 18) and post ( n = 57)-consensus definitions, there was a significant difference between age of diagnosis (30.710.2 vs. 41.3 ± 14.3; p = 0.001), age of symptom onset (18.4 +/15.2 vs. 32.4 ± 15.5), and initial esophageal diameter (10.5 ± 2.7 vs. 14.3 ± 4.2; p < 0.0001), respectively. Conclusions: Fibrostenotic EoE has steadily decreased, and inflammatory EoE is now the most recognized form. Across our 26-year experience, there was a decrease in delay in diagnosis and severity of esophageal stricture. The pivotal change occurred around 2007 corresponding to the first EoE guideline emphasizing the impact and importance of early detection of disease. [ABSTRACT FROM AUTHOR]

Objective. Esophageal food impaction (FI) is a common clinical problem with limited information on incidence. Previous population based studies are lacking. The incidence, main etiological factors, recurrence and outcome of FI was determined in the present study in a population based setting. Material and methods. This was a study of consecutive adult patients who presented with FI from 2008 to 2013 at the National University Hospital of Iceland. The mean crude incidence rate of FI was calculated. Retrospective analysis was undertaken on relevant clinical data such as type of bolus, management, complications, recurrence rate, risk factors for recurrence, and outcome. Results. Overall 308 patients had endoscopically confirmed FI, males 199/308 (65%), median age 62 years. The mean crude incidence was 25 per 100,000 inhabitants per year. The types of FI was meat (68%), fish (12%), vegetable (4%) and other food/objects (16%). Causes for the FI included: esophageal strictures (45%), hiatal hernia (22%), eosinophilic esophagitis (EoE) (16%) and esophageal carcinoma (2%). Recurrence appeared in 21%, in which 24/48 (50%) had EoE vs. 40/260 (15%) in others ( p = 0.0001). The removal of the foreign body was successful in 98% of the cases during the first endoscopy. Endoscopic associated complications included four (1.3%) aspirations, one (0.3%) esophageal perforation and one Boerhaave syndrome at presentation (both had EoE). Conclusions. The incidence of FI is the highest reported to date. EoE was strongly associated with recurrence of FI. In a population based setting endoscopy is a safe and effective procedure for removing FI.
