Challenging assumptions about the demographics of eosinophilic gastrointestinal diseases: A systematic review. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. GLOBAL 2024; 3:100260. [PMID: 38745866 PMCID: PMC11090865 DOI: 10.1016/j.jacig.2024.100260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 01/24/2024] [Accepted: 03/08/2024] [Indexed: 05/16/2024]
Abstract
Background The demographic characteristics of patients with eosinophilic gastrointestinal diseases (EGIDs) are poorly understood. Population-based assessments of EGID demographics may indicate health disparities in diagnosis. Objectives We aimed to characterize the demographic distribution of EGIDs and evaluate the potential for bias in reporting patient characteristics. Methods We conducted a systematic review, extracting data on age, sex, gender, race, ethnicity, body mass index, insurance, and urban/rural residence on EGID patients and the source population. Differences in proportions were assessed by chi-square tests. Demographic reporting was compared to recent guidelines. Results Among 50 studies that met inclusion/exclusion criteria, 12 reported ≥1 demographic feature in both EGID and source populations. Except for age and sex or gender, demographics were rarely described (race = 4, ethnicity = 1, insurance = 1) or were not described (body mass index, urban/rural residence). A higher proportion of male subjects was observed for EoE or esophageal eosinophilia relative to the source population, but no difference in gender or sex distribution was observed for other EGIDs. "Sex" and "gender" were used interchangeably, and frequently only the male proportion was reported. Reporting of race and ethnicity was inconsistent with guidelines. Conclusion Current data support a male predominance for EoE only. Evidence was insufficient to support enrichment of EGIDs in any particular racial, ethnic, or other demographic group. Population-based studies presenting demographics on both cases and source populations are needed. Implementation of guidelines for more inclusive reporting of demographic characteristics is crucial to prevent disparities in timely diagnosis and management of patients with EGIDs.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is increasing in prevalence but there is a lack of population-based studies. We sought to determine the prevalence, demographics, and associated atopic diseases in the Veterans Affairs (VA) population. METHODS A nationwide analysis of data from the VA patient population was done using a Veterans Health Administration database. EoE was identified using ICD9 (530.13) and ICD10 (K20.0) codes from October 2008 to June 2020. Demographic data, smoking status, BMI, treatment, and ICD codes for atopic diagnoses were collected. Two sample proportion z-tests, Chi-square tests, two-sample t tests, and one-way ANOVA were used to assess associations across demographic categories. RESULTS We identified a total of 11,775 patients with an EoE diagnosis: 91% male, 83% White, 8.6% Black, and 5% were of Hispanic ethnicity. The prevalence of EoE increased over time. At diagnosis, the mean age was 48.5 years overall, 51.6 years for Black patients, 45.3 years for Hispanic patients, and 48.2 years for Whites. Dysphagia was the most common symptom overall, but a higher percentage of Blacks and females were found to report chest pain (p < 0.0001, h = 0.32). With the exception of urticaria and atopic dermatitis, both Blacks and Hispanics had a higher incidence of atopic conditions compared to other races and ethnicities (p < 0.0001). CONCLUSION While EoE is seen primarily in White males, our study shows that a notable percentage of patients were Black or Hispanic, suggesting that EoE should be considered in non-white patients. The later age of diagnosis in this group could represent a lack of awareness about EoE among non-white patients. More research is needed to study these associations.

Abstract
Eosinophilic gastrointestinal diseases (EGIDs) including eosinophilic esophagitis (EoE) are rare diseases in which eosinophils abnormally infiltrate the gastrointestinal tract. Because these are rare diseases, there is limited information regarding race and ethnicity in EGIDs and even less is known about the impact of socioeconomic factors. There is some evidence that access to care in rural settings may be affecting epidemiologic understanding of EGIDs in the pediatric populations. Future work should try to evaluate bias in research and strive for representation in clinical trials and medicine.

Abstract
BACKGROUND We explored inflammatory bowel disease (IBD) and eosinophilic esophagitis (EoE) coexistence using a global dataset. Investigating their epidemiology, risks, and impact, we aimed to enhance the understanding of concurrent diagnoses and patient outcomes. METHODS A retrospective population-based cohort study was conducted using deidentified patient data from the TriNetX database (2011-2022). We estimated the incidence and prevalence of EoE in patients with IBD, including both Crohn's disease (CD) and ulcerative colitis (UC), and vice versa. Risks of select immune-mediated conditions and disease complications were compared among patients with EoE, IBD, or concurrent diagnoses. RESULTS Our results included 174,755 patients with CD; 150,774 patients with UC; and 44,714 patients with EoE. The risk of EoE was significantly higher among patients with CD (prevalence ratio [PR] 11.2) or UC (PR 8.7) compared with individuals without IBD. The risk of IBD was higher in patients with EoE (CD: PR 11.6; UC: PR 9.1) versus those without EoE. A propensity-matched analysis of IBD patients revealed that, when comparing patients with and without EoE, the relative risk of immune-mediated comorbidities was significantly greater for celiac disease, IBD-related inflammatory conditions, eczema and asthma (CD: n = 1896; UC: n = 1231; p < 0.001). Patients with a concurrent diagnosis of EoE and IBD had a higher composite risk of IBD-related complications (CD: adjusted HR (aHR) 1.14, p < 0.005; UC: aHR 1.17, p < 0.01) and lower risk of food bolus impaction (aHR 0.445, p = 0.0011). CONCLUSION Simultaneous EoE and IBD increased IBD-related complications risk, needing more treatment (glucocorticoids, biologic therapy, abdominal surgery), while reducing EoE-related issues like food bolus impaction.

Abstract
Celiac disease (CeD) and eosinophilic esophagitis (EoE) are immune-mediated disorders that can occur in the same patient. A retrospective study at a tertiary care hospital was conducted to determine the prevalence of EoE in a pediatric population with CeD and to compare characteristics of patients with both diseases to patients with CeD-only. Among the 148 patients with CeD identified in the study, 11 patients had both CeD and EoE (7.4%). Patients with both CeD and EoE had a higher absolute eosinophil count (per μL) at diagnosis compared to patients with CeD-only (454.1 ± 122.7 vs 231.9 ± 19.4, P = .003). In conclusion, there was a higher proportion of EoE in patients with CeD than would be expected in the general population, suggesting a potential pathophysiological overlap between the 2 diseases. An elevated peripheral absolute eosinophil count may help predict which patients with CeD may additionally have EoE.

Abstract
Food security encompassess the concept of access by all people at all times to enough food for an active, healthy life. Conversely, food insecurity (FI) refers to household-level economic and social conditions of limited or uncertain access to adequate food. FI is a key social determinant of health that can negatively affect nutrition and health outcomes, as it is estimated that 10.2% of the US population meets criteria for FI. Recognizing the impact of FI on our patients and families is critical to promote health equity and optimize health outcomes. This review focuses on FI and allergic disease from the perspective of key multisector stakeholders within the field of allergy and immunology as well as from the larger health care arena, highlighting key resources and initiatives important to patients. Collectively, as specialists in allergy and immunology, and within the medical field more broadly, we must leverage our unique roles as we interface with patients and families and serve as committed advocates for change. Developing innovative strategies to promote health equity can provide a pathway forward for all children, adults, and families to gain access to healthy, nutritious food as part of their routine lifestyle. This is a call to action.

Abstract
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
BACKGROUND The presentation of eosinophilic esophagitis (EoE) is heterogeneous, but trends over time are not known. AIM To determine whether clinical and endoscopic phenotypes at EoE diagnosis have changed over the past 2 decades. METHODS In this retrospective cohort study, adults and children with newly diagnosed EoE were phenotyped as follows: (1) inflammatory vs fibrostenotic vs mixed on endoscopy; (2) atopic vs non-atopic; (3) age at symptom onset; (4) age at diagnosis; (5) presence of autoimmune or connective tissue disease; and (6) responsive to steroids. The prevalence of different phenotypes was categorized by 5-year intervals. Multivariate analysis was performed to assess for changes in patient features over time. RESULTS Of 1187 EoE patients, age at diagnosis increased over time (from 22.0 years in 2002-2006 to 31.8 years in 2017-2021; p < 0.001) as did the frequency of dysphagia (67% to 92%; p < 0.001). Endoscopic phenotypes were increasingly mixed (26% vs 68%; p < 0.001) and an increasing proportion of patients had later onset of EoE. However, there were no significant trends for concomitant autoimmune/connective tissue disease or steroid responder phenotypes. On multivariate analysis, after accounting for age, dysphagia, and food impaction, the increase in the mixed endoscopic phenotype persisted (aOR 1.51 per each 5-year interval, 95% CI 1.31-1.73). CONCLUSION EoE phenotypes have changed over the past two decades, with increasing age at diagnosis and age at symptom onset. The mixed endoscopic phenotype also increased, even after controlling for age and symptomatology. Whether this reflects changes in provider recognition or disease pathophysiology is yet to be elucidated.

Abstract
BACKGROUND Prior work suggests eosinophilic oesophagitis (EoE) is rare in those aged over 65 years. However, elderly patients with EoE experience a substantial diagnostic delay from symptom onset to diagnosis. AIMS To assess if age predicted whether oesophageal biopsies were obtained in patients with EoE symptoms, what clinical features predict EoE in the elderly, and if EoE phenotype differs between elderly and non-elderly patients. METHODS We conducted a retrospective cohort study utilising the University of North Carolina (UNC) electronic medical record, EoE clinicopathologic database and UNC endoscopy software from July 2008 to April 2021. A sample of 193 elderly and non-elderly patients with dysphagia, chest pain and/or heartburn were assembled. Patients with EoE were newly diagnosed per contemporaneous guidelines. Patient demographics, clinical characteristics and procedural data were extracted. Summary statistics, bivariate and multivariate analyses were performed. RESULTS Of 193 patients, we included 91 elderly (47%) and 102 non-elderly (53%). Age independently predicted the odds of biopsies (adjusted odds ratio (aOR): 0.44 elderly vs. non-elderly; 95% CI: 0.21-0.92). Endoscopic features of EoE, but not symptoms, were more common in elderly than non-EoE elderly patients. Elderly patients with EoE differed from non-elderly only by time to diagnosis (aOR per year of symptoms preceding diagnosis: 1.08, 95% CI: 1.04-1.11). CONCLUSIONS Elderly patients with EoE have <50% the odds of oesophageal biopsies. There were no significant differences between elderly and non-elderly EoE patients, although endoscopic features helped discriminate the two groups. Our findings suggest that older age represents a barrier to EoE diagnosis.

Abstract
Our understanding of the influence of race and gender on the presentation of eosinophilic esophagitis (EoE) is incomplete. To address this gap, we examined the effect of race and gender on the presentation of EoE. In this retrospective study, we reviewed the medical records of 755 EoE patients and recorded their demographic, clinical, endoscopic, and histologic information. Descriptive statistics were used to characterize the cohort. Multivariate logistic regression was used to identify predictors of race and gender after accounting for potential confounders. There was a bimodal distribution for age at diagnosis of EoE. Approximately 43% had pediatric onset EoE, while 57% had adult onset EoE. Male (68%) predominance was observed. Dysphagia (57%) and abdominal pain (20%) were among the most common presenting symptoms. Multivariate analysis revealed that African Americans (AAs) were diagnosed earlier [aOR: 0.96 (95% CI: 0.95-0.99); P = 0.01] and had significantly lower odds of manifesting furrows [aOR: 0.30 (95% CI: 0.12-0.77); P = 0.01] as compared with Whites. Males were diagnosed earlier [aOR 0.98 (0.97-0.99; P = 0.04] and had higher odds of having abnormal endoscopic findings [aOR: 1.43 (1.05-1.97); P = 0.02] when compared with females. Race and gender influence the presentation of EoE. Future studies aimed at investigating the interplay between race, gender, and molecular mechanisms of EoE are warranted.

Abstract
INTRODUCTION It is still unknown whether eosinophilic esophagitis (EoE) patients with localized disease are different from those with extended disease. METHODS We evaluated prospectively included patients in the Swiss EoE cohort. Data on all patients with active disease at baseline, no concomitant gastroesophageal reflux disease, no strictures at baseline, and at least one follow-up visit were analyzed. We compared patients with histologically localized proximal versus distal versus extended (=proximal and distal) disease with regard to patient, disease characteristics, disease presentation, and development of complications. RESULTS We included 124 patients with a median of 2.5 years of follow-up (73.4% males, median age 35.0 years). Ten patients had proximal (8.1%), 46 patients had distal (37.1%), and 68 patients had extended disease (54.8%). Patients with proximal disease were significantly more often females (80%) compared with patients with distal (26.1%, p = 0.002) or extended disease (19.1%, p < 0.001) and reported less severe symptoms (VAS 0 vs. VAS 1, p = 0.001). Endoscopic and histological disease was less pronounced in the proximal esophagus of proximal EoE compared to extended disease (EREFS 1.0 vs. 3.0, p = 0.001; 27.0 eos/hpf vs. 52.5 eos/hpf, p = 0.008). Patients with proximal disease were less likely to undergo dilation compared to patients with distal disease in the follow-up (3.3% vs. 23.3%, p = 0.010). In a multivariate Cox regression model, proximal eosinophilia was less likely to be associated with treatment failure compared to distal eosinophilia. CONCLUSION Although isolated proximal EoE is infrequent, it is associated with less severe disease and better disease outcome. Proximal disease appears to present a unique EoE phenotype.

Abstract
PURPOSE OF REVIEW Eosinophilic esophagitis (EoE) is an allergic inflammatory esophageal disorder with a complex underlying genetic and molecular etiology. The interest of the scientific community in EoE has grown considerably over the past three decades, and the understanding of the genetic and molecular mechanisms involved in this disease has greatly increased. RECENT FINDINGS In this article, we aim to provide both historic aspects and updates on the recent genetic and molecular advances in the understanding of EoE. Although EoE is a relatively newly described disorder, much progress has been made toward identifying the genetic and molecular factors contributing to the disease pathogenesis by a variety of approaches with next-generation sequencing technologies, including genome-wide association study, whole exome sequencing, and bulk and single-cell RNA sequencing. This review highlights the multifaceted impacts of various findings that have shaped the current molecular and genetic landscape of EoE, providing insights that facilitate further understanding of the disease process.

Genome-wide admixture and association analysis identifies African ancestry-specific risk loci of eosinophilic esophagitis in African Americans. J Allergy Clin Immunol 2023; 151:1337-1350. [PMID: 36400179 PMCID: PMC10164699 DOI: 10.1016/j.jaci.2022.09.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 09/17/2022] [Accepted: 09/28/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Eosinophilic esophagitis (EoE), a chronic allergic inflammatory disease, is linked to multiple genetic risk factors, but studies have focused on populations of European ancestry. Few studies have assessed Black or African American (AA) populations for loci involved in EoE susceptibility. OBJECTIVE We performed admixture mapping (AM) and genome-wide association study (GWAS) of EoE using participants from AA populations. METHODS We conducted AM and GWAS of EoE using 137 EoE cases and 1465 healthy controls from the AA population. Samples were genotyped using molecular evolutionary genetics analysis (MEGA). Genotype imputation was carried out with the Consortium on Asthma Among African-Ancestry Populations in the Americas (CAAPA) reference panel using the Michigan Imputation Server. Global and local ancestry inference was carried out, followed by fine mapping and RNA sequencing. After quality control filtering, over 6,000,000 variants were tested by logistic regression adjusted for sex, age, and global ancestry. RESULTS The global African ancestry proportion was found to be significantly lower among cases than controls (0.751 vs 0.786, P = .012). Case-only AM identified 3 significant loci (9p13.3, 12q24.22-23, and 15q11.2) associated with EoE, of which 12q24.22-23 and 9p13.3 were further replicated in the case-control analysis, with associations observed with African ancestry. Fine mapping and multiomic functional annotations prioritized the variants rs11068264 (FBXW8) and rs7307331 (VSIG10) at 12q24.23 and rs2297879 (ARHGEF39) at 9p13.3. GWAS identified 1 genome-wide significant locus at chromosome 1p22.3 (rs17131726, DDAH1) and 10 other suggestive loci. Most GWAS variants were low-frequency African ancestry-specific variants. RNA sequencing revealed that esophageal DDAH1 and VSIG10 were downregulated and ARHGEF39 upregulated among EoE cases. CONCLUSIONS GWAS and AM for EoE in AA revealed that African ancestry-specific genetic susceptibility loci exist at 1p22.3, 9p13.3, and 12q24.23, providing evidence of ancestry-specific inheritance of EoE. More independent genetic studies of different ancestries for EoE are needed.

Abstract
BACKGROUND Indirect consequences of COVID-19 in eosinophilic esophagitis (EoE) are not known. AIM To determine the impact of COVID-19-related endoscopy cancellations on outcomes in EoE patients. METHODS In this retrospective cohort study, we assessed whether adult EoE patients who had routine endoscopy scheduled from mid-March 2020 to May 2020 (pandemic start) were canceled or proceeded, and if canceled, ultimately returned. We extracted clinical, endoscopic, and histologic data for their pre-COVID procedure as well as the next procedure performed, if a patient returned. Outcomes included histologic response (< 15 eos/hpf) and endoscopic severity. Those with delayed care were compared to those who returned as scheduled. RESULTS Of 102 patients identified, 75 had procedures canceled, and 20 (27%) never returned. For the 55 who were canceled but returned, mean time between procedures was 1.1 ± 0.7 years with a delay of 0.5 ± 0.3 years. While treatment rates were similar between the pre- and delayed post-COVID EGD, more patients required a dilation after their return (71% vs 58%; p = 0.05) and their esophageal diameter had significantly decreased (16.8 mm to 15.0 mm; p < 0.001). Of 17 individuals who did not have stricture, narrowing, or dilation pre-pandemic, during their next endoscopy 5 (29%) had a stricture, 1 (6%) had a narrowing, and 7 (41%) required dilation. CONCLUSION Of EoE patients with canceled endoscopies during the beginning of the COVID-19 pandemic, > 25% never returned for care, which is a previously unmeasured impact of the pandemic. Those who returned had > 1 year between procedures with progression of fibrotic features and need for esophageal dilation.

Abstract
Eosinophilic esophagitis (EoE) is a chronic and progressive immune-mediated disease of the esophagus associated with antigen-driven type 2 inflammation and symptoms of esophageal dysfunction. Our understanding of EoE pathophysiology has evolved since its initial recognition more than 20 years ago and has translated into diagnostic and novel therapeutic approaches that are affecting patient care. The mechanisms underlying disease development and progression are influenced by diverse factors, such as genetics, age, allergic comorbidities, and allergen exposures. Central to EoE pathophysiology is a dysregulated feed-forward cycle that develops between the esophageal epithelium and the immune system. Allergen-induced, type 2-biased immune activation by the esophageal epithelium propagates a cycle of impaired mucosal barrier integrity and allergic inflammation, eventually leading to tissue remodeling and progressive organ dysfunction. Herein, we review the current understanding of fundamental pathophysiological mechanisms contributing to EoE pathogenesis.

Abstract
A subset of patients with eosinophilic esophagitis (EoE) respond to proton-pump inhibitor (PPI) therapy, however they cannot be distinguished prior to PPI trial and the mechanism of PPI response remains unclear. Improved understanding of the distinct patient phenotypes in PPI-responsive EoE (PPI-r-EoE), PPI-non-responsive EoE (PPI-nr-EoE) and erosive esophagitis (EE) may help guide management. The aim of this paper is to compare the clinical and allergy profiles of PPI-r-EoE versus PPI-nr-EoE and EE. This was a retrospective case-control study of EoE patients (>15 eos/hpf on esophageal biopsies) at a tertiary center. EE controls were identified from the pathology database. EoE patients were classified as PPI-r-EoE or PPI-nr-EoE based on histologic response to twice-daily PPI for ≥8 weeks. Patient demographics, comorbidities, symptoms, allergy history and endoscopic findings were recorded. Univariate analyses were performed using the Fisher-exact test or t-test. Multivariable analyses were performed using logistic regression. In all, 104 EoE (57 PPI-r-EoE/47 PPI-nr-EoE) and 80 EE subjects were included. On multivariable analyses, allergic conditions (aOR 20.1, P < 0.0001) and rings (aOR 108.3, P = 0.001) were independent predictors for PPI-r-EoE versus EE, whereas allergic conditions (aOR 4.8, P = 0.03), rings (aOR 27.5, P = 0.002) and furrows (aOR 17.1, P = 0.04) were independent predictors for PPI-nr-EoE versus EE. Esophageal rings was the only significant predictor found in PPI-nr-EoE versus PPI-r-EoE (OR 2.5, P = 0.03). Allergic conditions and esophageal rings are significantly more prevalent in PPI-r-EoE and PPI-nr-EoE compared with EE. PPI-r-EoE appears clinically similar to PPI-nr-EoE and significantly different from EE. Further studies are needed to delineate the underlying pathophysiology of PPI-r-EoE versus PPI-nr-EoE.

Abstract
Introduction Eosinophilic Esophagitis (EoE) is a chronic condition characterized by eosinophilic inflammation of the esophagus which leads to esophageal dysfunction with common symptoms including vomiting, feeding difficulty, dysphagia, abdominal pain. Current main treatment options of EoE include dietary elimination and swallowed steroids. Diet elimination approach could lead to identifying the trigger food(s), but it often requires repeated upper endoscopy with general anesthesia and potentially could negatively affect nutrition intake and growth of the child and individuals' quality of life. Although the swallowed steroid treatment of effective, the EoE will universally recur after discontinuation of the treatment. Digestive Tea formula (DTF) has been used by the Traditional Chinese Medicine (TCM) practice to improve GI symptoms in EoE patients, including abdominal pain, GE reflux, and abnormal bowel movement. Previously, a flavonoid small molecule compound 7, 4 dihydroxy flavone (DHF) from Glycyrrhiza uralensis in DTF inhibited eotaxin, Th2 cytokine and IgE production in vitro and in vivo. Method This study comprehensively evaluates the potential therapeutic and immunological mechanisms underlying DHF improvement of symptoms related to EoE using computational modeling, including target mining, gene ontology enrichment, pathway analyses, protein-protein interaction analyses, in silico molecular docking and dynamic simulation followed by ex-vivo target validation by qRT-PCR using cultured human esophagus biopsy specimen with or without DHF from patients with EoE. Results Computational analyses defined 29 common targets of DHF on EoE, among which TNF-α, IL-6, IL1β, MAPK1, MAPK3 and AKT1 were most important. Docking analysis and dynamic simulation revealed that DHF directly binds TNF-α with a free binding energy of -7.7 kcal/mol with greater stability and flexibility. Subsequently, in the human esophagus biopsy culture system, significant reduction in levels of TNF-α, IL-6, IL-8 and IL1-β was found in the supernatant of biopsy sample cultured with DHF. Furthermore, the gene expression profile showed significant reduction in levels of TNF-α, IL1-β, IL-6, CCND and MAPK1 in the esophagus biopsy sample cultured with DHF. Discussion Taken together, the current study provides us an insight into the molecular mechanisms underlying multi-targeted benefits of DHF in the treatment of EoE and paves the way for facilitating more effective EoE therapies.

Abstract
Introduction: Asthma is a chronic disease, characterized by reversible airway obstruction, hypersensitivity reactions, and inflammation. Oral corticosteroids are an important treatment option for patients with severe or steroid-resistant asthma. Biologics for asthma are recommended in patients with severe asthma, owing to their steroid-sparing effect as well as their ability to reduce the severity and aggravation of uncontrolled asthma. Most clinical trials of omalizumab in patients with asthma have suggested its tolerability and safety. However, some studies reported eosinophilic comorbidities in the ear, nose, and throat during omalizumab treatment, particularly eosinophilic otitis media. This study examined the relationship between ear disorders and omalizumab compared with that of other biologics for asthma using a large real-world database. Materials and Methods: Individual case safety reports from the Uppsala Monitoring Centre Vigibase of biologics for asthma (omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab) up to 29 December 2019, were used. A disproportionality analysis was performed using the proportional reporting ratio (PRR), reporting odds ratio (ROR), and information components (IC). A hierarchy analysis used the Medical Dictionary for Regulatory Activities Terminology. A tree map was generated using R studio version 4.2. Results: In 32,618 omalizumab reports, 714 adverse events (AEs) were detected as signals. Among the 714 signals, seventeen AEs were detected as signals of omalizumab-related ear and labyrinth disorders in 394 reports. Only three AEs (ear pain, ear disorder, and ear discomfort) were detected from mepolizumab. No signal was detected from reslizumab, benralizumab, and dupilumab. Conclusions: Careful monitoring of ear disorders is recommended when omalizumab treatment is started, with decreased oral corticosteroid use in patients with severe asthma. Further studies are necessary to confirm the omalizumab-related signals.

Abstract
Endoscopy plays a critical role in caring for and evaluating the patient with eosinophilic esophagitis (EoE). Endoscopy is essential for diagnosis, assessment of response to therapy, treatment of esophageal strictures, and ongoing monitoring of patients in histologic remission. To date, less-invasive testing for identifying or grading EoE severity has not been established, whereas diagnostic endoscopy as integral to both remains the criterion standard. Therapeutic endoscopy in patients with adverse events of EoE may also be required. In particular, dilation may be essential to treat and attenuate progression of the disease in select patients to minimize further fibrosis and stricture formation. Using a modified Delphi consensus process, a group of 20 expert clinicians and investigators in EoE were assembled to provide guidance for the use of endoscopy in EoE. Through an iterative process, the group achieved consensus on 20 statements yielding comprehensive advice on tissue-sampling standards, gross assessment of disease activity, use and performance of endoscopic dilation, and monitoring of disease, despite an absence of high-quality evidence. Key areas of controversy were identified when discussions yielded an inability to reach agreement on the merit of a statement. We expect that with ongoing research, higher-quality evidence will be obtained to enable creation of a guideline for these issues. We further anticipate that forthcoming expert-generated and agreed-on statements will provide valuable practice advice on the role and use of endoscopy in patients with EoE.

Abstract
Eosinophilic esophagitis (EoE) is an emerging chronic inflammatory disease of the oesophagus and is clinically characterized by upper gastrointestinal (GI) symptoms including dysphagia and esophageal food impaction. Histopathologic manifestations, which include intraepithelial eosinophilic inflammation and alterations of the esophageal squamous epithelium, such as basal zone hyperplasia (BZH) and dilated intercellular spaces (DIS), are thought to contribute to esophageal dysfunction and disease symptoms. Corroborative clinical and discovery science-based studies have established that EoE is characterized by an underlying allergic inflammatory response, in part, related to the IL-13/CCL26/eosinophil axis driving dysregulation of several key epithelial barrier and proliferative regulatory genes including kallikrein (KLK) serine proteases, calpain 14 (CAPN14) and anoctamin 1 (ANO1). The contribution of these inflammatory and proliferative processes to the clinical and histological manifestations of disease are not fully elucidated. Herein, we discuss the immune molecules and cells that are thought to underlie the clinical and pathologic manifestations of EoE and the emerging therapeutics targeting these processes for the treatment of EoE.

Sex Impacts Disease Activity But Not Symptoms or Quality of Life in Adults With Eosinophilic Esophagitis. Clin Gastroenterol Hepatol 2022; 20:1729-1738.e1.

Abstract
BACKGROUND Eosinophilic esophagitis has a strong male predominance that appears at least partially due to genetic susceptibility. However, data regarding sex-related differences in patients with EoE are scarce. METHODS We analyzed prospectively collected data from adults enrolled into the Swiss Eosinophilic Esophagitis Cohort Study. Patients with and without dilation in the past 12 months completed patient-reported Eosinophilic Esophagitis Activity Index (EEsAI) and EoE-specific quality of life in adults (EoE-QoL-A) and underwent endoscopy with biopsies. We used linear regression with EEsAI or EoE-QoL-A as the outcome, eosinophils per high power field, rings and strictures, current therapy use, and disease duration as predictors. RESULTS A total of 266 patients (77% male, median age at diagnosis 35.8 years, median disease duration 10.4 years) were seen during 408 visits. Men had a longer diagnostic delay (62 months vs 36 months; P = .022), higher endoscopic disease activity (median endoscopic reference score 3.0 [interquartile range, 1.0-6.0] vs 2.0 [interquartile range, 0.0-4.0]; P = .010), more microabscesses (25% vs 13%; P = .025), and more often fibrosis of the lamina propria (mild/moderate 74.7% vs 61.5%, severe 9.1% vs 5.8%; P = .047) than women. When adjusting for objective measures of disease activity, disease duration, and current therapy use, we did not observe differences in EEsAI or EoE-QoL-A between women and men. CONCLUSIONS Male EoE patients had higher endoscopic and histologic disease activity than female patients. When adjusting for biologic activity and therapy use, we did not identify differences in symptom severity or EoE-QoL between male and female eosinophilic esophagitis patients.

Abstract
Eosinophilic esophagitis (EoE) has been associated with autoimmune (AI) and connective tissue disorders (CTDs), but clinical correlates and treatment response to topical corticosteroids (tCS) for patients with both conditions are not well known. We aimed to determine the prevalence and clinical features of AI/CTDs in EoE patients, and assess the response to tCS. In this retrospective cohort study of adults and children newly diagnosed with EoE in the University of North Carolina EoE Clinicopathologic database, we extracted clinical characteristics and treatment response data. We compared EoE patients with and without AI/CTDs, identified independently associated factors, and explored treatment responses. Of 1029 EoE patients, 61 (5.9%) had an AI/CTDs. The most common AI/CTDs were psoriasis/psoriatic arthritis (P/PA) (1.7%), Hashimoto's (1.2%), and rheumatoid arthritis (RA) (1%). Compared to those without AI/CTDs, AI/CTDs patients were older (35 vs. 28 years, P = 0.004), more likely to be female (51% vs. 30%, P = 0.001), have insurance (93% vs. 78%, P = 0.004) and a longer symptom duration prior to EoE diagnosis (10 vs. 7 years, P = 0.02). Older age, female sex, having insurance, and having allergic rhinitis were independently associated with AI/CTDs. AI/CTD patients with EoE were less likely to have a symptom response (47% vs. 79%, P = 0.003). Overlap between EoE and AI/CTDs was uncommon, seen in approximately 6%, with P/PA, Hashimoto's, and RA being most frequent. In conclusion, older age, female sex, having insurance, and allergic rhinitis were independently associated with AI/CTDs. EoE patients with AI/CTDs had less symptom response, with trendtowards lower endoscopic and histologic responses, to tCS therapy.

Abstract
BACKGROUND Pediatric patients with eosinophilic esophagitis (EoE) experience heterogeneous symptoms and the patient's age may preclude reliable self-report of symptoms. OBJECTIVE The goal of this study was to develop a patient-reported outcome and an observer-reported outcome questionnaire to evaluate the signs and symptoms of EoE in pediatric patients (≥1 to <12 y of age) in a clinical trial setting. METHODS A concept-focused literature review, expert advice meetings, and concept elicitation interviews with pediatric EoE patients and their caregivers were conducted to identify disease-related signs and symptoms. Instructions, items, and response options were drafted. Cognitive debriefing interviews were conducted to evaluate children's and caregivers' ability to understand and respond to the questionnaires and to evaluate the comprehensiveness of the concepts measured. RESULTS Results from the literature review, expert advice meetings (n = 6), and concept elicitation interviews (n = 24) informed the development of the Pediatric Eosinophilic Esophagitis Sign/Symptom Questionnaire intended for use by patients (PESQ-P) with EoE 8 years or older to younger than 12 years and an observer-reported outcome questionnaire planned for use by caregivers of patients (PESQ-C) 1 year old or older to younger than 12 years. Both questionnaires measure the same concepts; the PESQ-P assesses the frequency, duration, and/or severity of symptoms and the PESQ-C assesses the presence/absence of the signs/symptoms. The cognitive debriefing interviews (n = 17) demonstrated that participants were able to comprehend and complete the questionnaires as intended. CONCLUSIONS This study provides evidence of the content validity of 2 novel questionnaires, PESQ-P and PESQ-C, designed to evaluate the symptom experience of pediatric EoE patients in a clinical trial setting.

Abstract
Eosinophilic esophagitis (EoE) is a disease entity that has become increasingly recognized in the pediatric population over the last decade and was first recognized as early as 1990. EoE is a clinicopathologic diagnosis with signs and symptoms varying between age groups. The clinical presentation of EoE is variable ranging from milder nonspecific symptoms, such as abdominal pain, vomiting, and dyspepsia, to more severe presentations such as failure to thrive, dysphagia and even food impaction and is dependent on age of diagnosis 2. There is growing body of evidence with regards to the pathophysiology, diagnostic modalities, and treatment options for EoE in the past decade. In this review article, we aim to discuss the disease burden, pathophysiology, diagnostic strategies, and currently available treatment options for EoE based on existing literature.

Abstract
OBJECTIVES The Pediatric Eosinophilic Esophagitis (EoE) Symptom Score version 2 (PEESSv2.0) is an EoE-specific validated metric for disease monitoring, but its use has not been explored outside of EoE. Our aim was to determine if PEESSv2.0 scores differentiate between children with EoE and non-EoE esophageal dysfunction undergoing initial esophagogastroduodenoscopy (EGD). METHODS A prospective cohort study of pediatric subjects was conducted. Children ages 1-18 undergoing initial EGD for esophageal dysfunction were enrolled. Demographics, clinical history, and child self-report and parent-proxy report PEESSv2.0 symptom scores were collected at the time of EGD. Esophageal biopsies were reviewed, and EoE was defined as >15 eosinophils/high powered field (hpf) seen in any level of the esophagus. Non-EoE was defined as <15 eosinophils/hpf. RESULTS Seventy-one children were included in the study from 2015 to 2018 [59% (42/71) males; mean age 9.2 years; range 1-17 years]. Fifty-eight percent (41/71) met criteria for EoE, and 42% (30/71) were labeled non-EoE. Non-EoE children and their parents had higher/worse median PEESSv2.0 total scores than those with EoE [47.0 vs 28.0 (P = 0.001) and 40.5 vs 26.5 (P = 0.012), respectively]. Non-EoE children reported higher median GERD [9.0 vs 4.0 (P = 0.003)], nausea/vomiting [9.0 vs 4.0 (P = 0.003)], and pain [11.0 vs 6.0 (P = 0.001)] subdomain scores compared to those with EoE. PEESSv2.0 dysphagia subdomain scores (child and parent-proxy) did not differ between EoE and non-EoE groups [22.0 vs 15.0 (P = 0.184) and 18.5 vs 17.4 (P = 0.330), respectively]. DISCUSSION Total PEESSv2.0 scores were worse in non-EoE group compared to EoE group. Although PEESSv2.0 is validated for use in monitoring EoE therapy, it does not distinguish children with EoE from non-EoE esophageal dysfunction at the time of diagnostic EGD.

Abstract
OBJECTIVES Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus that requires esophagogastroduodenoscopy (EGD) for diagnosis and treatment monitoring. We aimed to identify the frequency of endoscopic monitoring in children with EoE and observe the effect of age, race, socioeconomic factors, and atopy on the rate of endoscopy. METHODS We queried the Pediatric Health Information System over a 15-year period for ambulatory EGDs in children with EoE. Subjects with at least 1 year of data were included. Age, sex, ethnicity, race, insurance type, median household income, and atopy were collected for each subject. RESULTS 16,517 subjects were included (mean age 8.5 years). 3211 (19%) of subjects had ≥1 EGD per subject year (EGD/SY). Subjects >13 years old were more likely to have ≥1 EGD/SY compared to children 6-12 years (odds ratio [OR] 2.29, P < 0.001, 95% confidence interval [CI] = 2.06-2.54). Males were more likely to have ≥1 EGD/SY compared to females (OR 1.19, P < 0.001, 95% CI = 1.08-1.31). African-American subjects were 16% less likely than Caucasian subjects to have ≥1 EGD/SY (OR 0.84, P = 0.05, 95% CI = 0.71-1.00). Subjects with allergic rhinitis or anaphylaxis, food allergy, and/or oral allergy syndrome were more likely to have ≥1 EGD/SY (OR 1.67, P < 0.001, 95% CI = 1.47-1.90 and OR 3.65, P < 0.001, 95% CI = 3.25-4.11, respectively). CONCLUSIONS Nineteen percent of subjects had ≥1 EGD/SY. Older age, male sex, allergic rhinitis, and food allergies were associated with more frequent endoscopic monitoring in children with EoE. Caucasian subjects had more frequent endoscopy than African-American subjects. This study raises awareness about underrecognized variation in the care of children with EoE.

Abstract
There are several esophageal disorders that can occur in the pediatric population. Eosinophilic esophagitis (EoE) is an eosinophil predominant inflammatory disease of the esophagus that was first characterized in the early 1900's. EoE is the most common pediatric esophageal inflammatory condition after gastroesophageal reflux disease (GERD). Longstanding GERD is a known risk factor for the development of Barrett's esophagus (BE) in both children and adults. BE is associated with the development of dysplasia and, if left undiagnosed, may progress to the development of esophageal adenocarcinoma (EAC). EAC and esophageal squamous cell carcinoma (ESCC) comprise the majority of childhood esophageal malignant neoplasms. The prevalence of EoE continues to rise within the pediatric population. On the other hand, both BE and esophageal neoplasms remain extremely rare in children. The relationship between a chronic inflammatory condition like EoE to BE and/or esophageal neoplasms remains unclear. The current research of these disease entities is prioritized to further understanding the disease pathogenesis and disease progression, exploring new diagnostic modalities, and developing novel treatments or less invasive therapeutic options. The focus of the following narrative review is to provide a summary of the current clinical practices, future research and their implications on these various esophageal disorders.

Abstract
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.

Sex Differences in Blood Transcriptional Profiles and Clinical Phenotypes in Pediatric Patients with Eosinophilic Esophagitis. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:3350-3358.e8. [PMID: 34265446 DOI: 10.1016/j.jaip.2021.06.043] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 06/22/2021] [Accepted: 06/24/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an increasingly recognized, chronic inflammatory disease. Recent reports suggest clinical differences between males and females. OBJECTIVE To define the relevant molecular pathways that could be related to clinical phenotypes in children with EoE. METHODS We performed blood RNA expression analysis in children with newly diagnosed EoE and matched, healthy controls, and applied bioinformatics tools to define EoE host immune biosignatures. Questionnaires and medical records were used to characterize symptoms, esophagogastroduodenoscopy results, and treatment response. RESULTS Forty-one subjects (aged 2-17 years) were enrolled; the cohort consisted of 27 males and 14 females. Patients were randomly divided into a discovery cohort (21 EoE patients and 12 controls) that identified 544 significant differentially expressed transcripts (P ≤ .01; 1.25-fold change). Those 544 transcripts correctly classified most EoE patients in the validation cohort (n = 20) from healthy controls. Global transcriptional perturbation relative to healthy controls, Molecular Distance to Health scores were greater in EoE patients than controls (P = .003). When we analyzed subjects based on age and sex, males 13 years of age and older were more likely to have food impactions (P = .033) and to have higher endoscopic severity scores (P = .036). Separate group comparisons according to sex identified 294 differentially expressed transcripts in males and 643 transcripts in female EoE patients. Of those, 37 genes were shared and similarly expressed irrespective of sex. CONCLUSIONS Whole blood transcriptional analysis represents a promising noninvasive tool to assess activity of the immune/inflammatory response in children with EoE. Male and female EoE patients showed robust differences in gene expression suggesting distinct pathogenic endotypes.

Abstract
BACKGROUND Manifestations of pediatric eosinophilic esophagitis (EoE) are varied and dictated by multiple factors. The influence of race is limited to small observational cohorts of dichotomized data (Whites vs non-Whites) or single-racial analysis. OBJECTIVE To better understand phenotypic variability in the manifestation and atopic sensitization of pediatric EoE, from the perspective of race. METHODS Retrospective observational cohort study performed at a tertiary referral center. Subjects were included if less than 21 years old, with suggestive clinical features and histopathologic (>15 eosinophils/high-power field [hpf]) confirmation of EoE. Statistical computation was performed using Stata/IC 11 on variables of interest. RESULTS A total of 34 subjects were included in the analysis. The median (interquartile range [IQR]) age for initial atopy was 2 (1-5) years. The median (IQR) age for EoE diagnosis was 5 (3-8) years. Age of EoE diagnosis was higher for Black or African Americans than non-Black or African Americans (P = .01). Between the racial groups, there was no difference in the total number of food sensitizations (P = .13), yet environmental allergy testing revealed that Black or African Americans were more likely to be sensitized for weeds (P = .03), dog (P = .009), and mold (P = .006). On histopathologic analysis, Black or African American subjects were found to have more prominent midesophageal eosinophilia at median 50/hpf (20-80/hpf), whereas Hispanic or LatinXs have more prominent lower esophageal eosinophilia at median 40/hpf (IQR, 20-40/hpf), compared with the other races (P = .04 and P = .04, respectively). CONCLUSION Black or African Americans are more likely to present at an older age, have aeroallergen sensitization, and have more prominent midesophageal eosinophilia.

Abstract
Immunoglobulin E-mediated food allergy is an increasingly prevalent public health concern globally. In North America, particularly in the United States, racial and ethnic differences in food allergy prevalence and rates of sensitization have become apparent. Black and Hispanic children in the United States have been estimated to have the highest rates of food allergy. Beyond rates of prevalence, food allergy outcomes, such as health care utilization, psychosocial outcomes, and economic burden, also vary considerably by race and ethnicity. It is important to consider socioeconomic status in conjunction with race and ethnicity in studying differences in food allergy outcomes.

Abstract
BACKGROUND There is evidence that involving potential participants and the public in co-designing research can improve the quality of the study design, recruitment and acceptability of the research, but appropriate methodologies for doing this are not always clear. In this study we co-designed a way of involving people affected by a rare genomic disease in shaping future genomic research about the condition. The aim was to report the process, experiences and outcomes of involving people in genomic research in a standardised way, in order to inform future methods of involvement in research co-production. METHOD Participants were recruited from an online community hosted by an Australian-based rare disease charity and were over the age 18 years. Once people gave consent, we shared learning resources with participants and invited them to complete an online survey before joining a two-week facilitated online discussion, followed by a second online survey. We used the novel tool 'Standardised Data on Initiatives - Alpha Version 0.1' (STARDIT) to map preferences, plan involvement and report any outcomes from the process, with quantitative data analysed descriptively and qualitative data thematically analysed. RESULTS Of the 26 people who gave consent and completed the initial survey, 15 participated in the online discussion and 12 completed the follow-up survey. STARDIT was used to report six outcomes from the process, including 60% of participants' responses showing a change towards 'widening' their view of who should be involved in research to include more people. Outcomes also included an improved understanding of research and how to be involved. Participants enjoyed online discussions, found learning resources useful and asked to stay involved in the research process. The partner organisation reported that a similar online discussion will be used in future research prioritisation processes. CONCLUSION Involving people in co-designing the process improved the study design, ensuring it met the needs of participants. Whilst the study includes participants from only one disease group, using STARDIT allowed us to map people's preferences and report the methods and outcomes from involving people, providing a way for learning from this case study to inform future research studies beyond the discipline of public health genomics.

Abstract
AIM Considering the allergic basis of Eosinophilic esophagitis (EoE), this study was conducted to evaluate peripheral blood Tregs in children with EoE. BACKGROUND Eosinophilic esophagitis (EoE) is an allergic inflammatory disease of gastrointestinal tract. Regulatory T cells (Tregs) have a confirmed role in allergic disorders. METHODS Children with EoE, gastroesophageal reflux disease (GERD) and healthy controls (HC) (10 subjects in each group) were recruited after diagnosis by a pediatric gastroenterologist and allergist. After obtaining informed written consent, peripheral blood was obtained. Peripheral blood mononuclear cells were isolated by Ficoll gradient centrifugation. Flowcytometry was used to enumerate peripheral blood Tregs (CD4 +CD25 +FOXP3+ gated lymphocytes were considered as Tregs). RESULTS CD4+ gated lymphocytes significantly increased in EoE and GERD groups compared to HC group (p= 0.018). Tregs also was significantly increased in EoE in comparison to HC group (p=0.016). There were no statistically significant differences in Tregs of EoE as compared to GERD subjects (p=0.085). CONCLUSION Peripheral blood Tregs increase in patients with EoE as compared to healthy controls, which may be indicative of a feedback mechanism to regulate inflammatory responses.

Abstract
Eosinophilic esophagitis (EoE) is characterized by eosinophilic infiltration of the esophageal mucosa and symptoms of esophageal dysfunction, including dysphagia. While EoE is still considered a rare disease, in practice it seems that more and more cases are diagnosed every week, research in the field is exploding, and the pipeline for treatments contains multiple agents, some of which are quite far along the development pathway. After only scattered cases and small series were published in the late 1970s and 1980, Stephen Attwood, Thomas Smyrk, Tom DeMeester, and James Jones, published in Digestive Diseases and Sciences in 1993 a seminal report that described a clinicopathologic syndrome of esophageal eosinophilia with dysphagia. This review details the origins of this paper and compares and contrast what was observed then and what is known now about multiple aspects of EoE, including the clinical presentation, diagnosis, epidemiology, natural history, and treatments and outcomes. Moreover, it will highlight how the paper presaged a number of controversies in the field that have yet to be resolved, as well as foreshadowed the collaborative, multidisciplinary approach that has led to rapid advances.

Abstract
Eosinophilic esophagitis (EoE) is an allergen-driven chronic inflammatory condition, characterized by symptoms related to esophageal dysfunction and confirmed histologically by esophageal mucosal eosinophilia. Since its first description in the 1990s, the incidence and prevalence of EoE have been on the rise. It is known to affect all ages of various ethnic backgrounds and both sexes; however, it is most seen in White males. Children with EoE often present with abdominal pain, nausea, vomiting, and failure to thrive, whereas adults with EoE typically present with dysphagia and food impaction. Diagnosis of EoE requires histologic confirmation of elevated esophageal eosinophils in a symptomatic patient, and only after secondary causes have been excluded. Because EoE is a chronic and progressively fibrostenotic disease, treatment goals include resolution of symptoms, induction and maintenance of disease remission, and prevention and possibly reversal of fibrostenotic complications, while minimizing treatment-related adverse effects and improving quality of life. Treatment strategies include the "3 D's"-drugs, diet, and dilation. Standard drug therapies include proton-pump inhibitors and topical corticosteroids. Dietary therapies include elemental diet, allergy testing-directed elimination diet, and empiric elimination diets. Endoscopic esophageal dilation for EoE strictures can alleviate esophageal symptoms but has no effect on mucosal inflammation. Recent progress in EoE research has made possible evidence-based clinical guidelines. Ongoing pharmacologic trials show promise for novel biologic agents in the treatment of refractory EoE.

Abstract
BACKGROUND The incidence of eosinophilic esophagitis (EoE) is greater in male than female subjects, and the underlying molecular basis for this sex bias remains unclear. OBJECTIVE We sought to delineate the contribution of the sex hormone estrogen to the EoE phenotype and esophageal epithelial barrier function and remodeling. METHODS We performed demographic and incidence analyses of EoE in male and female subjects from a single-center pediatric cohort. Estrogen-responsive gene expression analyses and estrogen receptor (ESR) immunofluorescence staining of esophageal biopsy specimens from patients with EoE and control subjects were performed. The effect of 17β-estradiol (E2) on IL-13-induced signaling pathways, gene expression, and esophageal epithelial architecture and barrier function in a primary human esophageal keratinocyte cell (EPC2) culture system (EPC2-air-liquid interface) was examined. RESULTS We observed a male predominance in patients with EoE. Analyses of RNA sequencing data sets revealed a significant dysregulation of the estrogen-responsive gene network and expression of ESR1 and ESR2 in esophageal biopsy specimens from patients with EoE compared with control subjects. IL-13 stimulation of EPC2-air-liquid interface cells led to altered cellular architecture with induced dilation of intercellular spaces and barrier dysfunction. Pretreatment of EPC2s with E2 prior to IL-13 exposure abrogated IL-13-induced architectural changes and esophageal barrier dysfunction. Mechanistically, E2-protective effects were dependent on ESR2 and associated with diminishing of IL-13-induced tyrosine kinase 2 and signal transducer and activator of transcription 6 phosphorylation and EoE-dysregulated gene expression. CONCLUSIONS Estrogen-responsive genes are modified in patients with EoE compared with control subjects. E2 attenuated IL-13-induced architectural changes and esophageal epithelial barrier dysfunction through inhibition of the IL-13/tyrosine kinase 2/signal transducer and activator of transcription 6 pathway via ESR2-dependent process. Estrogen hormone signaling may protect against development of EoE in female subjects.

Abstract
Eosinophilic esophagitis (EoE) is defined as a chronic, immune/antigen-mediated esophageal disease that can lead to symptoms of esophageal dysfunction. This disease is seen in both children and adults. Approximately 70% of patients with EoE have food antigen sensitization or other atopic conditions, suggesting an allergic etiology in the pathogenesis of the disease. The role of allergy testing to identify foods that lead to EoE is unclear. Three types of allergy tests currently exist: skin prick testing, atopy patch testing, and immunoassays for serum food-specific immunoglobulin E. It is important for gastroenterologists to work in conjunction with allergist colleagues in the care of patients with EoE, particularly in the management of comorbid atopic conditions.

Abstract
Eosinophilic esophagitis (EoE) is a chronic allergic/ immune-mediated esophageal disease. Knowledge related to the clinical presentation, pathogenesis, epidemiology, natural history, treatment, and outcomes of EoE has rapidly evolved over the past 2 decades. This article focuses on the similarly evolving diagnostic framework for EoE. In the initial clinical guidelines, diagnosis of EoE was based on symptoms of esophageal dysfunction; at least 15 eosinophils per high-power field (eos/hpf) on esophageal biopsy; and either a lack of response to high-dose proton pump inhibitor (PPI) therapy, or normal pH monitoring. The first 2 criteria have remained largely unchanged; however, the role of PPIs has been controversial, particularly due to the recognition of PPI-responsive esophageal eosinophilia (PPI-REE), in which patients with suspected EoE experience resolution of symptoms and esophageal eosinophilia with PPI therapy. A quickly expanding evidence base has found that most adult patients with EoE and PPI-REE share similar clinical, endoscopic, histologic, immunologic, and molecular characteristics prior to the use of PPIs. Because of this, the most recent diagnostic guidelines have removed the lack of response to PPIs as a diagnostic criterion; PPIs are now better considered as a treatment for esophageal eosinophilia. EoE should currently be suspected on a clinical basis when there are symptoms of esophageal dysfunction and at least 15 eos/hpf on esophageal biopsies. A history of atopy and endoscopic signs of EoE are strongly supportive of the diagnosis. However, the diagnosis cannot be confirmed until a thorough evaluation of other potential causes of esophageal eosinophilia has been performed.

Abstract
Adults and children with eosinophilic esophagitis (EoE) have distinct clinical and endoscopic presentations. Recognition of clinical signs, along with laboratory and endoscopic findings, is critical for the identification of patients with EoE because delay in diagnosis has been associated with esophageal remodeling and stricture formation. Clinical presentation varies considerably between adults and children. This is less due to differences in the disease and more due to patient differences. This article describes the similarities and differences in clinical presentation of children and adults with EoE, including areas of epidemiology, clinical and endoscopic presentation, pathophysiology, and treatment.

Abstract
Eosinophilic esophagitis (EoE) is an increasingly prevalent chronic condition characterized by eosinophilic infiltration of the esophageal epithelium accompanied by esophageal symptoms. The number of new diagnoses is growing worldwide in both pediatric and adult populations. Differences in disease distribution and presentation have been found, varying by gender, race, and other characteristics. This review examines the existing literature and provides insight into the demographic features of EoE.

The Prevalence of Biopsy-Proven Eosinophilic Esophagitis in Hispanics Undergoing Endoscopy Is Infrequent Compared to Caucasians: A Cross-Sectional Study. Dig Dis Sci 2017; 62:3511-3516. [PMID: 29086329 DOI: 10.1007/s10620-017-4791-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Accepted: 06/20/2017] [Indexed: 12/17/2022]
Abstract
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.

Long-Term Treatment of Eosinophilic Esophagitis With Swallowed Topical Corticosteroids: Development and Evaluation of a Therapeutic Concept. Am J Gastroenterol 2017; 112:1527-1535. [PMID: 28719593 DOI: 10.1038/ajg.2017.202] [Citation(s) in RCA: 84] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2017] [Accepted: 05/23/2017] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Swallowed topical corticosteroids (STCs) are efficacious in inducing and presumably maintaining remission in patients with active eosinophilic esophagitis (EoE). Hitherto, it has not been evaluated whether long-lasting remission can be achieved, and whether treatment can be stopped once patients have achieved this remission. METHODS Since 2007, EoE patients included into a large database at the Swiss EoE Clinics were put on STCs as induction/maintenance therapy. Disease activity was assessed on an annual basis. In patients who achieved long-lasting (≥6 months) clinical, endoscopic, and histological (=deep) remission, treatment was stopped. Data on all patients treated using this therapeutic strategy were analyzed retrospectively. RESULTS Of the 351 patients, 33 (9.4%) who were treated with STCs achieved deep remission. Median age of remitters at disease onset was 32.6 years (interquartile range (IQR) 19.1-49.3), and diagnostic delay was 5.4 years (IQR 1.2-11.4). Deep remission was achieved after 89.0 weeks (IQR 64.6-173.8). Female gender was the only independent prognostic factor for achieving deep remission (odds ratio (OR) 2.518, 95% confidence interval (CI) 1.203-5.269). Overall, STCs were stopped after 104.7 weeks (IQR 65.5-176.6). No mucosal damage was observed upon histological examination. In 27 of the 33 remitters (81.8%), a clinical relapse occurred after a median of 22.4 weeks (95% CI 5.1-39.7). Six remitters (18.2%) did not experience a clinical relapse during a follow-up of 35.1 weeks (IQR 18.3-44.9). Hence, a total of 1.7% (6/351) patients were able to discontinue STCs in the long term. CONCLUSIONS Long-term EoE treatment with STCs was well tolerated, but only a minority achieved deep remission. Female gender is the only prognostic factor for attainment of such remission. After treatment cessation, the majority experienced a clinical relapse.

Abstract
Eosinophilic esophagitis is a chronic, antigen-driven, eosinophil-predominant inflammatory disease of the esophagus and affects both children and adults. Cutting-edge technologies, such as genome-wide association studies, have advanced our understanding of the disease pathogenesis at a remarkable rate. Recent insights from genetic and mechanistic studies have concluded that a complex interplay between genetic and environmental risk factors, allergic sensitization, and esophageal-specific pathways leads to disease pathogenesis. Importantly, recent epidemiologic studies have found that the incidence and prevalence of eosinophilic esophagitis continue to rise. New guidelines have advocated the elimination of the term proton pump inhibitor (PPI)-responsive esophageal eosinophilia and have recommended using PPIs as a first-line treatment modality. Systemic reviews and meta-analyses confirm the efficacy of PPIs, topical corticosteroids, and empiric food elimination diets. Unmet needs include the development of birth cohort studies, validated diagnostic scoring systems, minimally invasive disease-monitoring methods, and the development of new therapies.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus diagnosed by the presence of esophageal symptoms accompanied by an esophageal eosinophilic infiltrate. EoE has an increasing worldwide prevalence and can be a cause of dysphagia and food impactions. There is an important role for the use of proton pump inhibitors in the diagnostic pathway of EoE. Treatment paradigms for EoE aim to minimize esophageal inflammation and improve symptom control. Dietary therapy targets dietary allergens and encompasses the elemental diet, the allergy testing-directed elimination diet, and the empiric elimination diet. Pharmacologic options include topical corticosteroids as the standard first-line treatment. Multiple other pharmacologic interventions are currently under investigation and are not recommended in the most recent guidelines. Endoscopic dilation is usually reserved for patients who relapse on pharmacologic or dietary regimens or who have symptomatic stricturing disease. This article provides a comprehensive discussion of existing diagnostic and management strategies for EoE.

Abstract
BACKGROUND Environmental factors associated with ethnicity may contribute to the occurrence of eosinophilic esophagitis. Our study aimed to investigate the influence of Helicobacter pylori on the ethnic variation of esophageal eosinophilia in a large national sample of patients undergoing esophago-gastro-duodenoscopy. METHODS The Miraca Life Sciences Database is an electronic repository of histopathologic patient records. A case-control study evaluated the influence of ethnicity on the occurrence of esophageal eosinophilia and how age, gender, and histologic diagnosis of H. pylori modify this relationship. RESULTS The total study population comprised 596 479 subjects, of whom 25 969 harbored a diagnosis of esophageal eosinophilia. Young age, male sex, and H. pylori infection in declining order exerted the strongest influence on the occurrence of esophageal eosinophilia. In comparison with the population comprising of Caucasians and African-Americans, esophageal eosinophilia was less common among patients of African (OR=0.10, 95% CI=0.01-0.46), Middle Eastern (0.22, 0.15-0.31), East Asian (0.32, 0.26-0.38), Indian (0.28, 0.21-0.37), Hispanic (0.40, 0.37-0.43), or Jewish descent (0.58, 0.51-0.66), but more common among patients of Northern European descent (1.25, 1.07-1.45). With the exception of Northern Europeans, all ethnic subgroups were characterized by a higher prevalence of H. pylori than the comparison group. A low prevalence of H. pylori was significantly associated with a high prevalence of esophageal eosinophilia (R2 =0.90, P<.001). CONCLUSION Esophageal eosinophilia prevalence markedly varies by patient ethnicity. As there is a strong inverse correlation between H. pylori and esophageal eosinophilia, H. pylori infection may be in part responsible for the observed ethnic distribution of esophageal eosinophilia.

Abstract
BACKGROUND Thirty percent of children with food allergies have multiple simultaneous allergies; however, the features of these multiple allergies are not well characterized serologically or clinically. OBJECTIVE We comprehensively evaluated 60 multifood-allergic patients by measuring serum IgE to key allergen components, evaluating clinical histories and medication use, performing skin tests, and conducting double-blind, placebo-controlled food challenges (DBPCFCs). METHODS Sixty participants with multiple food allergies were characterized by clinical history, DBPCFCs, total IgE, specific IgE, and component-resolved diagnostics (IgE and IgG4) data. The food allergens tested were almond, egg, milk, sesame, peanut, pecan, walnut, hazelnut, cashew, pistachio, soy, and wheat. RESULTS Our data demonstrate that of the reactions observed during a graded DBPCFC, gastrointestinal reactions occurred more often in boys than in girls, as well as in individuals with high levels of IgE to 2S albumins from cashew, walnut, and hazelnut. Certain food allergies often occurred concomitantly in individuals (ie, cashew/pistachio and walnut/pecan/hazelnut). IgE testing to components further corroborated serological relationships between and among these clustered food allergies. CONCLUSIONS Associations of certain food allergies were shown by DBPCFC outcomes as well as by correlations in IgE reactivity to structurally related food allergen components. Each of these criteria independently demonstrated a significant association between allergies to cashew and pistachio, as well as among allergies to walnut, pecan, and hazelnut.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by symptoms of esophageal dysfunction and eosinophilic infiltration of the esophageal mucosa. The diagnosis requires esophageal biopsies demonstrating at least 15 eosinophils per high-powered field following a course of high-dose proton pump inhibitors. Management of EoE consists of the three Ds: drugs, dietary therapy, and esophageal dilation. In this review, we discuss the epidemiology, pathogenesis, diagnosis, and treatment of EoE to include the role of emerging therapies.
