Abstract
ABSTRACT Eosinophilic esophagitis is an antigen-mediated chronic inflammatory disorder that has risen in incidence and prevalence over the past 2 decades. The clinical presentation is variable and consists of mainly esophageal symptoms such as dysphagia, heartburn, food impaction, and vomiting. Current management relies on dietary elimination, proton-pump inhibitors, and topical corticosteroids with different response rates and relapses after treatment discontinuation. With a better understanding of the underlying pathophysiology, many molecules emerged recently as targeted treatment including dupilumab (IL4/IL13 blocker), as the first FDA-approved biological treatment, which has changed the management paradigm.

Novel transcriptomic panel identifies histologically active eosinophilic oesophagitis. Gut 2024; 73:1076-1086. [PMID: 38670631 PMCID: PMC11187384 DOI: 10.1136/gutjnl-2023-331743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Accepted: 04/11/2024] [Indexed: 04/28/2024]
Abstract
BACKGROUND AND AIMS Eosinophilic oesophagitis (EoE) is characterised by symptoms of esophageal dysfunction and oesinophil tissue infiltration. The EoE Diagnostic Panel (EDP) can distinguish between active and non-active EoE using a set of 77 genes. Recently, the existence of distinct EoE variants featuring symptoms similar to EoE, such as oesophageal dysfunction but lacking eosinophil infiltration, had been determined. METHODS We used oesophageal biopsies from patients with histologically active (n=10) and non-active EoE (n=9) as well as from healthy oesophageal controls (n=5) participating in the Swiss Eosinophilic Esophagitis Cohort Study (SEECS) and analysed the gene expression profile in these biopsies by total RNA-sequencing (RNA-seq). Moreover, we employed the publicly accessible RNA-seq dataset (series GSE148381) as reported by Greuter et al, encompassing a comprehensive genomic profile of patients presenting with EoE variants. RESULTS A novel, diagnostic gene expression panel that can effectively distinguish patients with histologically active conventional EoE from patients with EoE in histological remission and control individuals, and from three newly discovered EoE variants was identified. Histologically Active EoE Diagnostic Panel (HAEDP) consists of 53 genes that were identified based on differential expression between histologically active EoE, histological remission and controls (p≤0.05). By combining the HAEDP with EDP, we expanded our knowledge about factors that may contribute to the inflammation in EoE and improved our understanding of the underlying mechanisms of the disease. Conversely, we suggested a compact group of genes common to both HAEDP and EDP to create a reliable diagnostic tool that might enhance the accuracy of EoE diagnosis. CONCLUSION We identified a novel set of 53 dysregulated genes that are closely associated with the histological inflammatory activity of EoE. In combination with EDP, our new panel might be a valuable tool for the accurate diagnosis of patients with EoE as well as for monitoring their disease course.

Abstract
INTRODUCTION Multiple pharmacological interventions have been studied for managing eosinophilic esophagitis (EoE). We performed a comprehensive systematic review and network meta-analysis of all available randomized controlled trials (RCT) to assess the efficacy and safety of these interventions in EoE in adults and children. METHODS We performed a comprehensive review of Embase, PubMed, MEDLINE OVID, Cochrane CENTRAL, and Web of Science through May 10, 2023. We performed frequentist approach network meta-analysis using random effects model. We calculated the odds ratio (OR) with 95% CI for dichotomous outcomes. RESULTS Our search yielded 25 RCTs with 25 discrete interventions and 2067 patients. Compared with placebo, the following interventions improved histology (using study definitions) in decreasing order on ranking: orodispersible budesonide (ODB) low dose, ODB high dose, oral viscous budesonide (OVB) high dose, fluticasone tablet 1.5 mg twice daily, fluticasone 3 mg twice daily, esomeprazole, dupilumab every 2 weeks, dupilumab weekly, OVB medium dose, fluticasone 3 mg daily, cendakimab 180 mg, prednisone, swallowed fluticasone, fluticasone tablet 1.5 mg daily, OVB low dose, reslizumab 3 mg/kg, reslizumab 1 mg/kg, and reslizumab 2 mg/kg. CONCLUSIONS Network meta-analysis demonstrates histological efficacy of multiple medications for EoE. Because of the heterogeneity and large effect size, we recommend more trials comparing pharmacotherapeutic interventions with each other and placebo. An important limitation of this study is absence of clinical efficacy data due to insufficient data. Other limitations include heterogeneity of operator, population, and outcome analysis.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition characterized by the eosinophil infiltration of the esophagus (>15 per high power field). Recently, there has been an increase in both the incidence and prevalence of the disease. The common modalities of treatment are dietary modification, proton pump inhibitors, and steroids. However, the United States Food and Drug Administration has not approved any drugs for the treatment of EoE. This review has discussed the role of steroids in the treatment of EoE, focusing on the various formulations of the drug, its dosage, drug delivery, and duration of therapy. The study also covers the common outcomes of steroid therapy and its side effects.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic immune mediated inflammatory disorder of the esophagus. It is still unknown why children and adults present differently, and there is little evidence about why it is more common in men than women. OBJECTIVE Our aim was to synthesize published and unpublished esophageal bulk RNA-sequencing (RNA-seq) data to gain novel insights into the pathobiology of EoE and examine the differences in EoE transcriptome by sex and age group. METHODS Esophageal bulk RNA-seq data from 5 published and 2 unpublished studies resulting in 137 subjects (EoE: N = 76; controls: N = 61) were analyzed. For overall analysis, combined RNA-seq data of patients with EoE were compared with those of controls and subgroup analysis was conducted in patients with EoE by age of the patient (children [<18 years] vs adults [≥18 years]) and sex (female vs male). Gene-set enrichment analysis, ingenuity pathway analysis (IPA), cell-type analysis, immunohistochemistry, and T-cell or B-cell receptor analysis were performed. RESULTS Overall analysis identified dysregulation of new genes in EoE compared with controls. IPA revealed that EoE is characterized by a mixed inflammatory response compared with controls. Cell-type analysis showed that cell composition varied with age: children had more mast cells, whereas adults had more macrophages. Finally, gene-set enrichment analysis and IPA revealed pathways that were differentially regulated in adults versus children and male versus female patients with EoE. CONCLUSIONS Using a unique approach to analyze bulk RNA-seq data, we found that EoE is characterized by a mixed inflammatory response, and the EoE transcriptome may be influenced by age and sex. These findings enhance insights into the molecular mechanisms of EoE.

Abstract
INTRODUCTION Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus with increasing prevalence worldwide. It is a multifactorial disease caused by a combination of immunologic, genetic, and environmental factors. The clinical presentation of EoE varies largely, especially between different age groups. While diagnostic criteria and therapeutic goals are similar in children and adults, there are differences in treatment, with a more cautious approach in children to avoid growth disturbances. In addition, close monitoring and follow-up are essential in children to ensure uninterrupted growth. AREAS COVERED A search in PubMed/MEDLINE, EMBASE, and SCOPUS databases was conducted to identify relevant studies published between January 2010 and January 2023 to give an overview of the state-of-the-art of EoE epidemiology, diagnosis, and treatment while focusing on similarities and differences between the adult and the pediatric population. EXPERT OPINION The current state of research indicates that while significant progress has been made in understanding and treating EoE, further research and advances are needed to optimize diagnostic strategies, tailored treatment approaches, monitoring, and follow-up, and improve long-term outcomes for patients. With further innovation, the management of EoE can become more precise and tailored, leading to better patient outcomes and improved quality of life.

Abstract
PURPOSE OF REVIEW The development of biological therapies for type 2 inflammatory diseases raises the possibility of addressing remission in those dis-immune conditions. No consensus exists for a definition of remission in chronic rhinosinusitis with nasal polyps (CRSwNP). This review aims to critically evaluate the published data to provide the basis for defining remission in CRSwNP. RECENT FINDINGS The published evidence has yet to provide an unequivocal definition on remission in type 2 inflammatory diseases, in part reflecting differences in approaches to diagnosis and follow-up. A multidimensional evaluation is necessary when considering complete remission, including clinical, inflammatory, and histologic criteria, but how to combine or tailor the three perspectives according to disease severity at baseline or timing of assessment of treatment category is yet to reach consensus. We suggest defining remission starting from the approach taken in asthma and eosinophilic esophagitis, that is, including the resolution of symptoms and improvements in objective parameters of disease severity and/or inflammatory activity. Future studies and consensuses should provide validated criteria with cutoffs for the day-to-day definition of remission. The definition of remission in CRSwNP should include the following criteria, to be verified and maintained for a period of ≥ 12 months: absence of symptoms (nasal obstruction, loss of smell, rhinorrhea as the main ones); no impact of symptoms on quality of life; no need of surgery; no chronic or rescue medications (systemic corticosteroids or antibiotics); and recovery of smell function, possibly evaluated by objective test. Assessment of underlying inflammation should also be considered once accurate and feasible biomarkers are available in clinical practice.

Abstract
PURPOSE OF REVIEW This review presents and summarizes the existing studies on the treatment goals and options for pediatric eosinophilic esophagitis utilizing rigorous peer-reviewed literature. RECENT FINDINGS In addition to traditional treatments, emerging biologic therapies continue to evolve the approach to treating pediatric eosinophilic esophagitis. Well defined treatment goals will aid the continued development of new therapies. Further, innovative assessment tools have changed how the clinician is able to assess the effectiveness of therapies with a trend toward less invasive options. The management of pediatric eosinophilic esophagitis continues to evolve with the advent of both novel treatment options and assessment tools. Treatment choices, with benefits and risks involved, should be presented to families upon diagnosis and tailored towards the individual patient and likelihood of adherence and success. Biologic therapy for EoE presents an exciting option for both first line therapy and escalation for those with severe or unresponsive disease.

Abstract
INTRODUCTION We previously identified 18 CpG methylation biomarkers associated with treatment response to topical corticosteroids (tCS) in eosinophilic esophagitis (EoE). In this study, in an independent cohort, we assessed the validity of these CpG sites as treatment response biomarkers. METHODS DNA was extracted from prospectively biobanked esophageal biopsies from patients with newly diagnosed EoE enrolled in a randomized trial of 2 tCS formulations. Histologic response was defined as <15 eosinophils per high-power field. Pretreatment DNA methylation was assayed on the Illumina Human MethylationEPIC BeadChip. Logistic regression and area under the receiver operating characteristic curve analyses, adjusting for chip, position on the chip, age, sex, and baseline eosinophil count, were computed to test for an association between DNA methylation and treatment response at the 18 previously identified CpG sites. RESULTS We analyzed 88 patients (58 histologic responders, 30 nonresponders), with a mean age of 38 ± 16 years, 64% male, 97% White race. Of the 18 CpG sites, 13 met quality control criteria, and 3 were associated with responder status ( P < 0.012), including sites within UNC5B (cg26152017), ITGA6 (cg01044293), and LRRC8A (cg13962589). All 3 showed evidence of reduced methylation in treatment responders, consistent with the original discovery associations. The predictive probability for nonresponse with all 3 CpG sites was strong (area under the receiver operating characteristic curve = 0.79). DISCUSSION We validated epigenetic biomarkers (CpG methylation sites) for the prediction of tCS response in patients with EoE in an independent population. While not all previously identified markers replicated, 3 demonstrated a relatively high predictive probability for response to treatment and hold promise for guiding tCS treatment in EoE.

Abstract
Eosinophilic esophagitis is an increasingly common inflammatory allergic disease of the esophagus characterized by esophageal eosinophilia and symptoms of esophageal dysfunction. The therapeutic landscape has rapidly evolved for this emerging type 2 inflammatory disorder. We review traditional therapies including updates and expert opinions in addition to promising therapies on the horizon and the history of therapies that failed to meet end points and highlight knowledge gaps for future investigations.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic, antigen-mediated disease of the esophagus commonly treated with swallowed topical steroids (STS) or elimination diets (EDs). Evidence of a long-term response to EDs in pediatric patients is sparse. OBJECTIVE Our study sought to understand the natural history of pediatric EoE treated exclusively with EDs and to examine a similar population of STS-treated EoE subjects. We hypothesized that long-term adherence to an effective ED would result in ongoing EoE disease remission. METHODS We conducted a retrospective study of pediatric EoE subjects who had at least 2 visits to a multidisciplinary clinic. Subjects were identified who had (1) a new referral with a suspected diagnosis of EoE; (2) received either EDs or STS alone, and (3) completed both a diagnostic and a posttreatment endoscopy. Concomitant proton-pump inhibitor use was allowed. We collected demographics, clinical features, treatment plans, and associated side effects on each subject. Remission was defined as fewer than 15 eosinophils/high-powered field. RESULTS We screened the electronic medical record from 2015 to 2016 for subjects cared for in the Gastrointestinal Eosinophilic Diseases Program who fit criteria for inclusion in this analysis. One hundred ninety-nine subjects were identified, 16 who received exclusive EDs and 15 who were treated with STS. Treatment of these subjects was documented for 4.8 and 5.2 years, respectively (P = .51). Significant differences between the groups were observed in average age at EoE diagnosis (3.5 y ED vs 7.8 y STS; P = .002) and in number of endoscopies (6.6 in ED vs 4.5 in STS; P = .03). Fifteen of 16 subjects treated with ED attained histological remission. The initial effective ED removed a mean of 7.7 foods and the final ED removed a mean of 4 foods. No food impactions or esophageal dilations occurred in the ED group. The STS group required an average of 3.7 dose/formulation changes, 4 subjects required 1 or more dilations, 1 subject had 2 food impactions, and 2 were diagnosed with adrenal insufficiency. CONCLUSIONS Treatment with either ED or STS can lead to long-term remission of EoE. In this study, fewer side effects developed in the ED group than the STS group, but the validity of this conclusion is limited by the small sample size and reinforces the need for prospective study to explore these initial findings.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic antigen-mediated eosinophilic inflammatory disease isolated to the esophagus. As a clinicopathologic disorder, a diagnosis of EoE requires a constellation of clinical symptoms of esophageal dysfunction and histologic findings (at least 15 eosinophils/high-powered microscope field (eos/hpf)). Current guidelines no longer require the failure of response to proton pump inhibitor medications to establish a diagnosis of EoE, but continue to suggest the exclusion of other etiologies of esophageal eosinophilia. The treatment goals for EoE are improvement in clinical symptoms, resolution of esophageal eosinophilia and other histologic abnormalities, endoscopic improvement, improved quality of life, improved esophageal function, minimized adverse effects of treatment, and prevention of disease progression and subsequent complications. Currently, there is no cure for EoE, making long-term treatment necessary. Standard treatment modalities include dietary modifications, esophageal dilation, and pharmacologic therapy. Effective pharmacologic therapies include corticosteroids, rapidly emerging biological therapies, and proton pump inhibitor medications. OBJECTIVES To evaluate the efficacy and safety of medical interventions for people with eosinophilic esophagitis. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, ClinicalTrials.gov, and WHO ICTRP to 3 March 2023. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing any medical intervention or food elimination diet for the treatment of eosinophilic esophagitis, either alone or in combination, to any other intervention (including placebo). DATA COLLECTION AND ANALYSIS Pairs of review authors independently selected studies and conducted data extraction and risk of bias assessment. We expressed outcomes as a risk ratio (RR) and as the mean or standardized mean difference (MD/SMD) with 95% confidence interval (CI). We assessed the certainty of the evidence using GRADE. Our primary outcomes were: clinical, histological, and endoscopic improvement, and withdrawals due to adverse events. Secondary outcomes were: serious and total adverse events, and quality of life. MAIN RESULTS We included 41 RCTs with 3253 participants. Eleven studies included pediatric patients while the rest recruited both children and adults. Four studies were in patients with inactive disease while the rest were in patients with active disease. We identified 19 intervention comparisons. In this abstract we present the results of the primary outcomes for the two main comparisons: corticosteroids versus placebo and biologics versus placebo, based on the prespecified outcomes defined of the primary studies. Fourteen studies compared corticosteroids to placebo for induction of remission and the risk of bias for these studies was mostly low. Corticosteroids may lead to slightly better clinical improvement (20% higher), measured dichotomously (risk ratio (RR) 1.74, 95% CI 1.08 to 2.80; 6 studies, 583 participants; number needed to treat for an additional beneficial outcome (NNTB) = 4; low certainty), and may lead to slightly better clinical improvement, measured continuously (standard mean difference (SMD) 0.51, 95% CI 0.17 to 0.85; 5 studies, 475 participants; low certainty). Corticosteroids lead to a large histological improvement (63% higher), measured dichotomously (RR 11.94, 95% CI 6.56 to 21.75; 12 studies, 978 participants; NNTB = 3; high certainty), and may lead to histological improvement, measured continuously (SMD 1.42, 95% CI 1.02 to 1.82; 5 studies, 449 participants; low certainty). Corticosteroids may lead to little to no endoscopic improvement, measured dichotomously (RR 2.60, 95% CI 0.82 to 8.19; 5 studies, 596 participants; low certainty), and may lead to endoscopic improvement, measured continuously (SMD 1.33, 95% CI 0.59 to 2.08; 5 studies, 596 participants; low certainty). Corticosteroids may lead to slightly fewer withdrawals due to adverse events (RR 0.64, 95% CI 0.43 to 0.96; 14 studies, 1032 participants; low certainty). Nine studies compared biologics to placebo for induction of remission. Biologics may result in little to no difference in clinical improvement, measured dichotomously (RR 1.14, 95% CI 0.85 to 1.52; 5 studies, 410 participants; low certainty), and may result in better clinical improvement, measured continuously (SMD 0.50, 95% CI 0.22 to 0.78; 7 studies, 387 participants; moderate certainty). Biologics result in better histological improvement (55% higher), measured dichotomously (RR 6.73, 95% CI 2.58 to 17.52; 8 studies, 925 participants; NNTB = 2; moderate certainty). We could not draw conclusions for this outcome when measured continuously (SMD 1.01, 95% CI 0.36 to 1.66; 6 studies, 370 participants; very low certainty). Biologics may result in little to no difference in endoscopic improvement, measured dichotomously (effect not estimable, low certainty). We cannot draw conclusions for this outcome when measured continuously (SMD 2.79, 95% CI 0.36 to 5.22; 1 study, 11 participants; very low certainty). There may be no difference in withdrawals due to adverse events (RR 1.55, 95% CI 0.88 to 2.74; 8 studies, 792 participants; low certainty). AUTHORS' CONCLUSIONS Corticosteroids (as compared to placebo) may lead to clinical symptom improvement when reported both as dichotomous and continuous outcomes, from the primary study definitions. Corticosteroids lead to a large increase in histological improvement (dichotomous outcome) and may increase histological improvement (continuous outcome) when compared to placebo. Corticosteroids may or may not increase endoscopic improvement (depending on whether the outcome is measured dichotomously or continuously). Withdrawals due to adverse events (dichotomous outcome) may occur less frequently when corticosteroids are compared to placebo. Biologics (as compared to placebo) may not lead to clinical symptom improvement when reported as a dichotomous outcome and may lead to an increase in clinical symptom improvement (as a continuous outcome), from the primary study definitions. Biologics lead to a large increase in histological improvement when reported as a dichotomous outcome, but this is uncertain when reported as a continuous outcome, as compared to placebo. Biologics may not increase endoscopic improvement (dichotomous outcome), but this is uncertain when measured as a continuous outcome. Withdrawals due to adverse events as a dichotomous outcome may occur as frequently when biologics are compared to placebo.

Abstract
BACKGROUND Patients with eosinophilic esophagitis (EoE) typically have concomitant atopic conditions, but whether there are differences in presentation or treatment response by the number of atopic diseases is unknown. OBJECTIVE To determine whether patients with EoE having multiple atopic conditions have differences in presentation or response to topical corticosteroid (TCS) treatment. METHODS We performed a retrospective cohort study of adults and children with newly diagnosed EoE. The total number of atopic comorbidities (allergic rhinitis, asthma, eczema, food allergy) was calculated. Patients with at least 2 atopic conditions other than allergic rhinitis were defined as having multiple atopic conditions and their baseline characteristics were compared with those with less than 2 atopic conditions. Histologic, symptom, and endoscopic responses to TCS treatment were also compared with bivariable and multivariable analyses. RESULTS Of the 1020 patients with EoE having atopic disease information, 235 (23%) had 1 atopic comorbidity, 211 (21%) had 2, 113 (11%) had 3, and 34 (3%) had 4. At baseline, the 180 (18%) patients with 2 or more atopic diseases were younger and had more vomiting, less abdominal pain, more exudates and edema on endoscopy, and higher peak eosinophil counts. Among those treated with TCS, there was a trend toward better global symptom response in patients with less than 2 atopic conditions, but there was no difference in histologic or endoscopic response compared with those with 2 or more atopic conditions. CONCLUSION There were differences in the initial presentation of EoE between those with and without multiple atopic conditions, but there were no major differences in histologic treatment response to corticosteroids by atopic status.

Abstract
Background and study aims Eosinophilic esophagitis (EoE) is a food allergen-induced disease of the esophagus. Chronic, eosinophil-predominant inflammation eventually leads to fibrosis, esophageal dysfunction and severe morbidity. Swallowed topical corticosteroids (STCs) are a mainstay of anti-inflammatory therapy in the treatment of active EoE. Data on the efficacy of novel corticosteroid formulations, developed specifically for esophageal delivery, have recently become available. Methods A comprehensive review was performed aiming to summarize evidence on the role of STCs in the treatment of EoE. Two biomedical bibliographic databases (PubMED, EMBASE) were searched for articles providing original information on the efficacy and safety of STCs in adult EoE patients. Results Budesonide orodispersible tablet (BOT) and budesonide oral suspension (BOS) both surpassed placebo formulations regarding the efficacy of inducing and maintaining histologic, symptomatic and endoscopic remission. Overall, BOT displayed the highest grade of efficacy with clinico-histologic remission rates up to 75% after 1 year. Fluticasone propionate (APT-1011) achieved and maintained histologic and endoscopic responses in the majority of patients, whereas only a positive trend was demonstrated for symptomatic improvement. Mometasone and ciclesonide were studied in a limited number of smaller-scale trials and placebo-controlled data are required to substantiate the promising findings. All STCs displayed a similar side effects profile and were generally considered safe and well-tolerated. Conclusions Current evidence supports long-term treatment with novel corticosteroid formulations, challenging the established treatment paradigm of EoE. BOT appears to be the most effective steroid therapy, although head-to-head comparative trials between STCs are needed.

Abstract
Eosinophilic esophagitis (EoE) is a chronic eosinophil inflammation that seems to be T helper type 2 antigen-driven. The disease is one of several eosinophilic gastrointestinal disorders in which there appears to be inflammation of the gastrointestinal tract without any apparent underlying causes. Differential diagnosis needs to be made with gastroesophageal reflux, which is characterized by chronic inflammation due to gastric refluxate from disorders related to motility. EoE, however, is considered a chronic allergic inflammatory disorder related to destructive tissue remodeling. There seems to be a higher prevalence of EoE in Western countries. It is typically found in atopic male individuals. Physiopathological risk factors include atopy, environmental factors, esophageal epithelial barrier dysfunctions, etc. EoE can cause several symptoms that include retrosternal burning sensation, dysphagia, food impaction, chronic reflux symptoms, nausea, and vomiting. Early diagnosis, which requires a biopsy to assess for esophageal inflammation, is essential for proper treatment. The aim of our brief overview is to summarize the current literature regarding the characteristics, diagnosis, complications, mechanisms of pathology, clinical features, influence of comorbidities, and treatment in patients with EoE.

Abstract
BACKGROUND Empirical elimination diets are effective for achieving histological remission in eosinophilic oesophagitis, but randomised trials comparing diet therapies are lacking. We aimed to compare a six-food elimination diet (6FED) with a one-food elimination diet (1FED) for the treatment of adults with eosinophilic oesophagitis. METHODS We conducted a multicentre, randomised, open-label trial across ten sites of the Consortium of Eosinophilic Gastrointestinal Disease Researchers in the USA. Adults aged 18-60 years with active, symptomatic eosinophilic oesophagitis were centrally randomly allocated (1:1; block size of four) to 1FED (animal milk) or 6FED (animal milk, wheat, egg, soy, fish and shellfish, and peanut and tree nuts) for 6 weeks. Randomisation was stratified by age, enrolling site, and gender. The primary endpoint was the proportion of patients with histological remission (peak oesophageal count <15 eosinophils per high-power field [eos/hpf]). Key secondary endpoints were the proportions with complete histological remission (peak count ≤1 eos/hpf) and partial remission (peak counts ≤10 and ≤6 eos/hpf) and changes from baseline in peak eosinophil count and scores on the Eosinophilic Esophagitis Histology Scoring System (EoEHSS), Eosinophilic Esophagitis Endoscopic Reference Score (EREFS), Eosinophilic Esophagitis Activity Index (EEsAI), and quality of life (Adult Eosinophilic Esophagitis Quality-of-Life and Patient Reported Outcome Measurement Information System Global Health questionnaires). Individuals without histological response to 1FED could proceed to 6FED, and those without histological response to 6FED could proceed to swallowed topical fluticasone propionate 880 μg twice per day (with unrestricted diet), for 6 weeks. Histological remission after switching therapy was assessed as a secondary endpoint. Efficacy and safety analyses were done in the intention-to-treat (ITT) population. This trial is registered on ClinicalTrials.gov, NCT02778867, and is completed. FINDINGS Between May 23, 2016, and March 6, 2019, 129 patients (70 [54%] men and 59 [46%] women; mean age 37·0 years [SD 10·3]) were enrolled, randomly assigned to 1FED (n=67) or 6FED (n=62), and included in the ITT population. At 6 weeks, 25 (40%) of 62 patients in the 6FED group had histological remission compared with 23 (34%) of 67 in the 1FED group (difference 6% [95% CI -11 to 23]; p=0·58). We found no significant difference between the groups at stricter thresholds for partial remission (≤10 eos/hpf, difference 7% [-9 to 24], p=0·46; ≤6 eos/hpf, 14% [-0 to 29], p=0·069); the proportion with complete remission was significantly higher in the 6FED group than in the 1FED group (difference 13% [2 to 25]; p=0·031). Peak eosinophil counts decreased in both groups (geometric mean ratio 0·72 [0·43 to 1·20]; p=0·21). For 6FED versus 1FED, mean changes from baseline in EoEHSS (-0·23 vs -0·15; difference -0·08 [-0·21 to 0·05]; p=0·23), EREFS (-1·0 vs -0·6; difference -0·4 [-1·1 to 0·3]; p=0·28), and EEsAI (-8·2 vs -3·0; difference -5·2 [-11·2 to 0·8]; p=0·091) were not significantly different. Changes in quality-of-life scores were small and similar between the groups. No adverse event was observed in more than 5% of patients in either diet group. For patients without histological response to 1FED who proceeded to 6FED, nine (43%) of 21 reached histological remission; for patients without histological response to 6FED who proceeded to fluticasone propionate, nine (82%) of 11 reached histological remission. INTERPRETATION Histological remission rates and improvements in histological and endoscopic features were similar after 1FED and 6FED in adults with eosinophilic oesophagitis. 6FED had efficacy in just less than half of 1FED non-responders and steroids had efficacy in most 6FED non-responders. Our findings indicate that eliminating animal milk alone is an acceptable initial dietary therapy for eosinophilic oesophagitis. FUNDING US National Institutes of Health.

Pre-treatment differential correlation of gene expression and response to topical steroids in eosinophilic esophagitis. Dis Esophagus 2023; 36:doac071. [PMID: 36222072 PMCID: PMC11220672 DOI: 10.1093/dote/doac071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 09/07/2022] [Accepted: 09/12/2022] [Indexed: 12/11/2022]
Abstract
Few predictors of response to topical corticosteroid (tCS) treatment have been identified in eosinophilic esophagitis (EoE). We aimed to determine whether baseline gene expression predicts histologic response to tCS treatment for EoE. We analyzed prospectively collected samples from incident EoE cases who were treated with tCS for 8 weeks in a development cohort (prospective study) or in an independent validation cohort (clinical trial). Whole transcriptome RNA expression was determined from a baseline (pre-treatment) RNA-later preserved esophageal biopsy. Baseline expression was compared between histologic responders (<15 eos/hpf) and non-responders (≥15 eos/hpf), and differential correlation was used to assess baseline gene expression by response status. In 87 EoE cases analyzed in the development set, there were no differentially expressed genes associated with treatment response (at false discovery rate = 0.1). However, differential correlation identified a module of 22 genes with statistically significantly high pairwise correlation in non-responders (mean correlation coefficient = 0.7) compared to low correlation in responders (coefficient = 0.3). When this 22-gene module was applied to the 89 EoE cases in the independent cohort, it was not validated to predict tCS response at the 15 eos/hpf threshold (mean correlation coefficient = 0.32 in responders and 0.25 in nonresponders). Exploration of other thresholds also did not validate any modules. Though we identified a 22 gene differential correlation module measured pre-treatment that was strongly associated with subsequent histologic response to tCS in EoE, this was not validated in an independent population. Alternative methods to predict steroid response should be explored.

Outcomes reported in randomized controlled trials for mixed and non-IgE-mediated food allergy: Systematic review. Clin Exp Allergy 2023; 53:526-535.

Abstract
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.

Abstract
Since the first description of eosinophilic oesophagitis (EoE) less than three decades ago, we have observed a striking increase in the number of patients diagnosed with EoE and the understanding of its clinical and immunopathogenic background. Nonetheless, a plethora of open questions await elucidation. In this Review, we discuss the current state of knowledge regarding the underlying mechanisms, particularly environmental factors and their interaction with genetic susceptibility. Subsequently, we discuss how to translate these factors into the diagnostic and therapeutic management of this chronic, immune-mediated disorder. Finally, we dissect the still long list of unmet needs, such as reasons for and handling refractory EoE and atypical clinical presentations. These open questions can guide us through future research steps and potentially foster reconsideration of the diagnostic guidelines of EoE.

Abstract
Topical steroids are commonly used in treatment of eosinophilic esophagitis (EoE), but currently there is lack of data to clarify most effective regimen. We aimed to study the achievement of histologic remission using the same dose of budesonide in two different delivery formulations. Patients with established EoE treated with pharmacy compounded budesonide capsule or budesonide Rincinol gel (both 3 mg twice daily) were studied retrospectively. Those with pre-treatment and post-treatment histologic assessment were included with main endpoint being histologic remission. 103 patients (62 gel, 41 capsule) were included, with higher rate of histologic remission with gel (84 vs. 59%, P=0.004). A subset of patients in both groups had lack of steroid response (<50% drop in eosinophils) (15% for gel, 32% for capsule). Formulation/delivery vehicle of steroid treatments to esophageal mucosa in EoE appears important for treatment efficacy, with budesonide gel having higher likelihood of histologic remission compared to budesonide capsules in our population. A truly steroid refractory group appears likely in our population. Larger, prospective studies may help clarify best regimen of topical steroids in EoE and may work to identify patients likely to benefit from alternative therapies.

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 The correlation between clinical and molecular treatment response thresholds in eosinophilic esophagitis (EoE) is not well understood. METHODS We evaluated posttreatment EoE diagnostic panel gene expression profiles across histologic and endoscopic thresholds (EREFS) in a prospective adult EoE cohort. RESULTS We observed a strong inverse correlation between posttreatment gene score and eosinophil count (R = -0.66; P < 0.001); biopsies with <15 eos/hpf had higher gene scores (≥425) vs those with ≥15 eos/hpf. Findings for EREFS were similar; EREFS ≤2 was associated with EoE diagnostic panel scores ≥395. DISCUSSION Molecular signatures support the use of posttreatment response thresholds <15 eos/hpf and EREFS ≤2 in clinical practice and trials.

Abstract
INTRODUCTION Dietary and pharmacological (proton pump inhibitors, swallowed topical corticosteroids) therapies are effective for induction of clinical and histological remission of eosinophilic esophagitis. However, data evaluating their long-term efficacy and safety is limited. AREAS COVERED Since eosinophilic esophagitis is chronic, clinical, endoscopic, and histological features usually recur when successful treatments are stopped. In untreated patients, persistent esophageal eosinophilic inflammation may progress to fibrostenosis over time, giving place to strictures and narrow-caliber esophagi. This article comprehensively reviews available data on long-term maintenance of eosinophilic esophagitis with pharmacological and dietary treatment. It also discusses limitations re: available literature and outlines data gaps on adherence to therapy and monitoring disease activity in the long-term. EXPERT OPINION Evidence indicates that long-term maintenance therapy may decrease the risk of esophageal stricture, food bolus impaction, and need for dilation in patients with eosinophilic esophagitis. Further knowledge on eosinophilic esophagitis phenotypes is needed to ascertain who will benefit best from sustained therapy. Unanswered questions include an adequate definition for sustained remission, best strategies for maintenance drugs and diets, enhancement of treatment adherence, and proper monitoring for long-term surveillance.

Abstract
Eosinophilic esophagitis is a chronic immune-mediated esophageal disease with a Th2 inflammatory response to inhalant and food allergens that cause an eosinophilic infiltration of esophageal mucosa. The diagnosis requires an upper endoscopy with esophageal bioptic samples, in particular the number of eosinophils must be >15 eos/high power field. The main symptoms of EoE in adults are dysphagia and food impaction, and its incidence is growing. Nowadays, the etiology of EoE is not well understood and no standard therapy is available. Therefore, the aim of this review was to analyze the major studies present in literature regarding the various therapeutic approaches to this disease.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated disorder characterised by eosinophilic inflammation and esophageal dysfunction symptoms. The recommended first-line treatment options are proton pump inhibitors and swallowed topical steroids (STS). However, current recommendations regarding STS are based on relatively few studies employing various doses and formulations. Our aim was to review the STS formulations currently used in the treatment of eosinophilic esophagitis, to demonstrate in a practical way the variety of exiting application methods, and to present emerging options for STS delivery to the esophagus. After the literature review, we established that the three most commonly used STS formulations include mist from an inhaler, viscous suspensions compounded with vehicles for oral use, and a recently introduced proprietary medication in the form of orodispersible tablets. Several drug delivery technologies with potential use in EoE are under investigation. To ensure optimal adherence, the choice of formulation should be based on efficacy, patient preferences and experience of the clinician, as well as current recommendations. Further studies are needed to compare the efficacy and acceptability of existing STS types, and to develop new, well-tolerated and effective drug formulations.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) can progress to fibrostenosis by unclear mechanisms. Herein, we investigated gene dysregulation in fibrostenotic EoE, its association with clinical parameters and specific pathways, and the functional consequences. METHODS Esophageal biopsies from subjects with EoE were collected across 11 Consortium of Eosinophilic Gastrointestinal Disease Researchers sites (n = 311) and 2 independent replication cohorts (n = 83). Inclusion criteria for fibrostenotic EoE were endoscopic rings, stricture, and/or a history of dilation. Endoscopic, histologic, and molecular features were assessed by the EoE Endoscopic Reference Score, EoE Histology Scoring System, EoE Diagnostic Panel, and RNA sequencing. Esophageal endothelial TSPAN12 expression and functional effects on barrier integrity and gene expression were analyzed in vitro. RESULTS TSPAN12 was the gene most correlated with fibrostenosis (r = -0.40, P < .001). TSPAN12 was lower in fibrostenotic EoE and correlated with EoE Endoscopic Reference Score, EoE Diagnostic Panel, and EoE Histology Scoring System (r = 0.34-0.47, P < .001). Lower TSPAN12 associated with smaller esophageal diameter (r = 0.44, P = .03), increased lamina propria fibrosis (r = -0.41, P < .001), and genes enriched in cell cycle-related pathways. Interleukin (IL)-13 reduced TSPAN12 expression in endothelial cells. Conversely, anti-IL-13 therapy increased TSPAN12 expression. TSPAN12 gene silencing increased endothelial cell permeability and dysregulated genes associated with extracellular matrix pathways. Endothelial cell-fibroblast crosstalk induced extracellular matrix changes relevant to esophageal remodeling. CONCLUSIONS Patients with fibrostenotic EoE express decreased levels of endothelial TSPAN12. We propose that IL-13 decreases TSPAN12, likely contributing to the chronicity of EoE by promoting tissue remodeling through fibroblast-endothelial cell crosstalk.

Abstract
BACKGROUND & AIMS Microbiota composition and mechanisms of host-microbiota interactions in the esophagus are unclear. We aimed to uncover fundamental information about the esophageal microbiome and its potential significance to eosinophilic esophagitis (EoE). METHODS Microbiota composition, transplantation potential, and antibiotic responsiveness in the esophagus were established via 16S ribosomal RNA sequencing. Functional outcomes of microbiota colonization were assessed by RNA sequencing analysis of mouse esophageal epithelium and compared with the human EoE transcriptome. The impact of dysbiosis was assessed using a preclinical model of EoE. RESULTS We found that the murine esophagus is colonized with diverse microbial communities within the first month of life. The esophageal microbiota is distinct, dominated by Lactobacillales, and demonstrates spatial heterogeneity as the proximal and distal esophagus are enriched in Bifidobacteriales and Lactobacillales, respectively. Fecal matter transplantation restores the esophageal microbiota, demonstrating that the local environment drives diversity. Microbiota colonization modifies esophageal tissue morphology and gene expression that is enriched in pathways associated with epithelial barrier function and overlapping with genes involved in EoE, including POSTN, KLK5, and HIF1A. Finally, neonatal antibiotic treatment reduces the abundance of Lactobacillales and exaggerates type 2 inflammation in the esophagus. Clinical data substantiated loss of esophageal Lactobacillales in EoE compared with controls. CONCLUSIONS The esophagus has a unique microbiome with notable differences between its proximal and distal regions. Fecal matter transplantation restores the esophageal microbiome. Antibiotic-induced dysbiosis exacerbates disease in a murine model of EoE. Collectively, these data establish the composition, transplantation potential, antibiotic responsiveness, and host-microbiota interaction in the esophagus and have implications for gastrointestinal health and disease.

[PMID: 35069803 PMCID: PMC8777364 DOI: 10.1177/17562848211068665] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Accepted: 12/03/2021] [Indexed: 02/04/2023] Open
Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. Left untreated, EoE progresses to fibrous remodeling and stricture formation that impairs quality of life. Therefore, EoE requires either repeated treatments or maintenance therapy. Current guidelines recommend swallowed topical corticosteroids (STCs), proton-pump inhibitors (PPIs), or dietary intervention as initial options to induce and maintain long-term disease remission. Impractical exclusive elemental diets and suboptimal allergy testing-directed food avoidance paved the way for empirical elimination diets. These are moderately effective and highly reproducible in inducing EoE remission and allow for identification of specific food triggers. Step-up strategies, including two- and four-food rather than six-food elimination diets, should be considered as initial approaches for dietary treatment in patients of all ages, as they reduce the need for endoscopic procedures, shorten diagnostic processing time, and avoid unnecessary restrictions. Formulations of STC originally designed for asthma therapy are suboptimal for EoE treatment, with new effervescent orodispersible tablets and viscose formulations designed to coat the esophageal mucosa providing increased effectiveness at reduced doses. The anti-inflammatory effects of PPI in EoE are independent from gastric acid secretion inhibition; despite evidence from observational research, PPIs are the most commonly prescribed first-line therapy for EoE due to their accessibility, low cost, and safety profile. Double doses of PPI only induce remission in half of EoE patients, irrespective of the drug used or patients' age. Inflammatory rather than stricturing EoE phenotype and treatment duration up to 12 weeks increase chances of achieving EoE remission. Most responders effectively maintain long-term remission with standard PPI doses. Finally, endoscopic dilation should be considered in patients with reduced esophageal caliber or persistent dysphagia despite histological remission. This article provides a state-of-the-art review and updated discussion of current therapies and newly developed options for EoE.

Abstract
Eosinophilic oesophagitis is a relapsing inflammatory disorder involving oesophagus identified over 30 years ago. Diagnosis is made by upper gastrointestinal endoscopy and oesophageal biopsies. There is huge variation in management practices across the globe. Therapeutic options include the use of proton pump inhibitors, topical steroids, and elimination diet. Biologics and immunomodulator drugs are being explored but not yet recommended in children. Long-term treatment may be required to control symptoms and to prevent complications such as fibrosis/stricture.Conclusion: Even though clinicians have better understanding of eosinophilic oesophagitis, further research is warranted in exploring the unmet needs of developing a highly sensitive non-invasive biomarker for its diagnosis and response to treatment along with a robust and easily deliverable therapeutic option. What is Known: •Incidence of eosinophilic oesophagitis has increased over the recent years. •Diagnostic confirmation requires upper gastrointestinal endoscopy and therapeutic options include elimination diet and/or topical steroids. What is New: •There is a lack of consensus ion management strategy with wide variation across the globe. •There is a need to develop a highly reliable and non-invasive biomarker to diagnose eosinophilic oesophagitis and to monitor the response to treatment.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic allergen-mediated disease of the esophagus. Pharmacologic treatment has largely relied on repurposing corticosteroids. Ciclesonide (CIC) is a corticosteroid for the treatment of asthma with biochemical properties that improve topical potency. OBJECTIVE To determine whether CIC decreased clinicopathological features of EoE. METHODS We performed a retrospective cohort study of patients with EoE treated with CIC at a pediatric hospital from 2010 to 2019. Data were extracted from the electronic health record. Patients who were prescribed CIC with pre- and post-CIC endoscopic and histological data available were included for analysis. RESULTS A total of 281 patients were treated with CIC and 81 met criteria for inclusion. Use of CIC was associated with reduced symptoms including dysphagia (P < .001), abdominal pain (P < .001), vomiting (P = .01), heartburn (P = .02), and behavior changes (P = .02). Average composite endoscopic reference scores decreased from 2.54 to 1.37 (P < .001), with improvement in exudates, edema, and furrows (all P < .001). Peak eosinophil counts decreased from 48 to 23 eosinophils/hpf (P < .001). Forty-three patients (53%) achieved remission (<15 eosinophils/hpf). Esophageal Candida was reported in 1 patient. Fasting morning cortisol concentrations were low in 10 of 31 patients tested. Six of these 10 patients had abnormal adrenocorticotropic hormone stimulation testing, 5 of 6 diagnosed with adrenal insufficiency before transition to CIC and 3 of 6 with subsequent normalization of adrenal function on CIC therapy. CONCLUSIONS Patients with EoE treated with CIC experienced significant reductions in clinicopathological features of EoE. CIC can be considered an alternative therapy in patients with known adrenal insufficiency or at risk of developing adrenal insufficiency.

Abstract
Eosinophilic oesophagitis (EoE) is a chronic, allergic disease associated with a T-lymphocyte response inducing esophageal eosinophilic infiltration in the esophagus. Inflammation and tissue fibrosis are responsible for the main clinical symptoms such as food impaction and dysphagia. The etiopathogenesis is multifactorial in which genetic and environmental factors coexist. The most common trigger is a non-IgE-mediated food allergy to milk, wheat, egg, soybean, nuts, fish, and seafood. The second factor we focus on is the contribution of genetic variation to the risk of EoE, describing the expression profile of selected genes associated with eosinophilic oesophagitis. We raise the topic of treatment, aiming to eliminate inflammation through an elimination diet and/or use of pharmacologic therapy with the use of proton pump inhibitors or steroids and endoscopic procedures to dilate the esophagus. We demonstrate that early diagnosis and effective treatment prevent the development of food impaction and decreased quality of life. The increasing presence of EoE requires bigger awareness among medical specialists concerning clinical features, the course of EoE, diagnostic tools, and management strategies.

Abstract
BACKGROUND Topical corticosteroids (TS) have become standard therapy for eosinophilic esophagitis (EoE). However, a variety of drug formulations have been used for which results of histological and clinical responses may be different. We aimed at determining the short-term histologic efficacy of TS for EoE based on randomized placebo-controlled trials and to review clinical response. METHODS We searched MEDLINE, ISI Web of Science, and clinicaltrials.gov for randomized controlled trials (RCTs) on TS versus placebo for active EoE published until June 2019. Treatment effects were calculated as risk ratios (RRs) comparing histologic remission between groups. RESULTS Nine RCTs (6 budesonide and 3 fluticasone) involving a total of 483 participants were included. A substantial overall effect of TS on acute histologic remission (RR 12.5, 95% confidence interval 6.0-25.9) was found despite varying definitions of histologic response. Indirect comparisons between drug and formulation types showed a trend for a better histologic efficacy of budesonide (RR 13.5 vs. 10.4 fluticasone) and for the orodispersible tablet (RR 46.2 vs. 11.5 suspension, and 10.4 nebulized formula/spray), but only based on small patient numbers. Scores used for clinical response assessment were different between studies, and short-term clinical results were less impressive: significant differences favoring TS were found in 4/9 RCTs (4/6 budesonide, 0/3 fluticasone). CONCLUSIONS TS are effective for short-term induction of histological remission in EoE with less impressive clinical response rates. The mode of drug delivery to the esophagus may be a relevant factor for the degree of histologic remission. Further trials should use uniform assessment criteria and long-term patient-centered outcomes.

Abstract
Food allergies are antigen-driven diseases that can lead to IgE-mediated reactions of immediate hypersensitivity (eg, anaphylaxis triggered by a single food) or non-IgE reactions of delayed hypersensitivity such as eosinophilic esophagitis (eg, inability to eat multiple foods manifesting as abdominal pain, choking, dysphagia, vomiting, reflux, food impaction). Although both types of disease have their own unique set of challenges in diagnosis and management, it is a particularly vexing problem when a patient is afflicted by both conditions. This situation can happen when individuals with IgE-mediated food allergy undergo desensitization using currently available forms of oral immunotherapy. In this Grand Rounds Review, we review diagnostic approaches to oral immunotherapy-associated eosinophilic esophagitis, potential relationships between primary and secondary eosinophilic esophagitis, potential management approaches, areas of uncertainty, and upcoming research. Optimally supporting patients in their journey with food allergy requires shared decision making regarding alternative management strategies and the stimulation of robust research.

Abstract
OBJECTIVES Topical corticosteroids are considered a cornerstone in the treatment of patients with eosinophilic esophagitis. The aim of this study was to evaluate the benefit of using mometasone furoate spray versus placebo on dysphagia and health-related quality of life in these patients. MATERIAL AND METHODS Consecutive, newly diagnosed adult patients with eosinophilic esophagitis were randomized and treated with either 200 micrograms of orally administered topical mometasone furoate or placebo 4 times daily for 8 weeks. Symptoms and quality of life were evaluated using questionnaires including the Watson Dysphagia Scale, the European Organization for Research and Treatment of Cancer Quality of Life-Oesophageal Module 18 and the Short Form-36 before and after treatment. RESULTS In the intention-to-treat analysis (n = 36) the Watson Dysphagia Scale score after mometasone treatment was reduced by 6.5 (median, p < .01) compared with 0 (median, ns) in the placebo group. The benefit of mometasone over placebo was significant (p < .05). In the per-protocol analysis (n = 33) the Watson Dysphagia Scale score was reduced by 5 (median, p = .01) after mometasone treatment compared with 0 (median, ns) in the placebo group. The advantage of mometasone over the placebo was significant (p < .05). The benefit of using mometasoneas evaluated by the two quality of life questionnaires was, however, insignificant. CONCLUSIONS Our finding suggests that in adult patients with eosinophilic esophagitis, topical mometasone furoate exerts a beneficial effect compared with placebo regarding the main symptom, i.e., dysphagia. A corresponding benefit could not be verified regarding the various quality of life measurements.

Abstract
BACKGROUND Network meta-analysis is used as a data synthesizer, incorporating direct and indirect evidence about treatments in a series of randomized control trials. OBJECTIVE To evaluate the comparative efficacy of various treatments for eosinophilic esophagitis (EoE). METHODS We performed a network meta-analysis to combine direct and indirect data to investigate the efficiency of drug therapies, which were evaluated in relevant randomized control trials for EoE. RESULTS Seventeen eligible studies (14 two-arm and 3 multiple-arm) were introduced to the meta-analysis. A total of 1011 patients were included, in whom 15 therapeutic interventions were used, namely: (1) budesonide oral suspension, (2) budesonide 1 mg orodispersible tablet twice daily, (3) budesonide 2 mg orodispersible tablet twice daily, (4) esomeprazole, (5) fluticasone, (6) nebulized steroid, (7) placebo, (8) prednisone, (9) anti-IL-5-mab (mepolizumab), (10) anti-IL-5-mab [reslizumab(1), ie, 1 mg/kg], (11) anti-IL-5-mab [reslizumab(2), ie, 2 mg/kg], (12) anti-IL-5-mab [reslizumab(3), ie, 3 mg/kg], (13) anti-IL-13-mab (QAX 576), (14) anti-IL-13-mab [RCP 4046 (180)], and (15) anti-IL-13-mab [RCP 4046 (360)]. Budesonide 1 mg orodispersible tablet twice daily showed the highest efficacy (SUCRA 0.91), whereas placebo was the least effective. In adult patients budesonide 1 mg orodispersible tablet twice daily remained the optimal treatment approach, whereas the corresponding therapeutic approach in pediatric patients was fluticasone. CONCLUSIONS This meta-analysis showed that budesonide 1 mg orodispersible tablet twice daily was the best treatment for EoE, as it was the most effective. This treatment remained the optimal approach in adult patients, whereas fluticasone was the best treatment in pediatric patients.

[PMID: 32272243 DOI: 10.1016/j.cgh.2020.03.060] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Revised: 02/28/2020] [Accepted: 03/27/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND & AIMS Quantification of eosinophilic esophagitis (EoE) symptoms is crucial for assessing treatment outcomes. We aimed to explore the effect of budesonide oral suspension (BOS) on dysphagia and pain with swallowing. METHODS We performed a secondary analysis of data from a phase 2 multicenter, double-blind, trial (conducted from July 2012 through October 2014) of patients with EoE, 11-40 y old, who were randomly assigned to groups given placebo or BOS (2.0 mg twice daily) for 12 weeks. Symptoms were quantified using the Dysphagia Symptom Questionnaire (DSQ) from baseline to week 12 of therapy. RESULTS Overall, 93 patients were randomly assigned to groups; the prespecified modified intention-to-treat analysis set comprised 87 patients (38 from the placebo group and 49 from the BOS group). Improvements from baseline in least-squares mean (standard error) DSQ (Q2+Q3) scores were observed. The difference between groups was statistically significant only at week 12 (placebo vs BOS: week 4, -4.9 [1.7] vs -7.4 [1.5]; P = .265; week 8, -7.4 [2.1] vs -10.3 [1.8]; P = .288; week 12, -7.5 [1.9] vs -14.3 [1.7]; P = .01). Similar findings were observed for pain (Q4) scores (placebo vs BOS: week 4, -2.5 [0.8] vs -3.3 [0.7]; P = .484; week 8, -3.0 [0.8] vs -4.9 [0.7]; P = .066; week 12, -3.1 [0.8] vs -4.9 [0.7]; P = .109). More severe DSQ and DSQ+pain scores were associated with presence of other symptoms (such as regurgitation) and physician-rated severity. Improvements in DSQ and DSQ+pain scores were greater in patients with either a histologic or endoscopic response than in patients without a response. CONCLUSIONS In a secondary analysis of data from a phase 2 trial of patients with EoE, we found evidence for improvements in dysphagia and pain scores in patients who received BOS (2.0 mg twice daily) vs placebo. Pain with swallowing should be considered in the clinical assessment of patients with EoE. ClinicalTrials.gov no: NCT01642212.

Abstract
BACKGROUND & AIMS The short-term efficacy of RPC4046, a monoclonal antibody against interleukin-13, has been shown in patients with eosinophilic esophagitis (EoE). We investigated the long-term efficacy and safety of RPC4046 in an open-label, long-term extension (LTE) study in adults with EoE. METHODS We analyzed data from 66 patients who completed the 16-week, double-blind, induction portion of a phase 2 study of RPC4046 (180 mg or 360 mg/wk) vs placebo and then completed a 52-week LTE, receiving open-label RPC4046 360 mg/wk. The study was conducted at 28 centers in 3 countries; patients were enrolled between September 2014 and January 2017. Outcomes were stratified by double-blind dose group and included esophageal eosinophil counts, EoE endoscopic reference score, EoE histologic scoring system score, symptom-based EoE activity index score, and safety. RESULTS By week 12 of the LTE, esophageal eosinophil mean and peak counts, total EoE endoscopic reference scores, and EoE histologic scoring system grade and stage scores did not differ considerably between patients who originally received placebo vs RPC4046. Most patients maintained responses through week 52. Symptom remission (symptom-based EoE activity index score, ≤20) increased from 14% at LTE entry to 67% at LTE week 52 in placebo‒RPC4046 patients and from 30% to 54% in RPC4046‒RPC4046 (either dose) patients. Of the 28 patients who did not have a histologic response to RPC4046 during the double-blind induction phase, 10 patients (36%) achieved response during the LTE. The most common adverse events were upper respiratory tract infection (21%) and nasopharyngitis (14%). CONCLUSIONS One year of treatment with RPC4046 is generally well tolerated and results in continued improvement and/or maintenance of endoscopic, histologic, and clinical measures of EoE disease activity relative to baseline. TRIAL REGISTRATION NCT02098473.

Steroid Eluting Esophageal-Targeted Drug Delivery Devices for Treatment of Eosinophilic Esophagitis. Polymers (Basel) 2021; 13:557. [PMID: 33668571 PMCID: PMC7917669 DOI: 10.3390/polym13040557] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 02/06/2021] [Accepted: 02/08/2021] [Indexed: 01/08/2023] Open
Abstract
Eosinophilic esophagitis (EoE) is a chronic atopic disease that has become increasingly prevalent over the past 20 years. A first-line pharmacologic option is topical/swallowed corticosteroids, but these are adapted from asthma preparations such as fluticasone from an inhaler and yield suboptimal response rates. There are no FDA-approved medications for the treatment of EoE, and esophageal-specific drug formulations are lacking. We report the development of two novel esophageal-specific drug delivery platforms. The first is a fluticasone-eluting string that could be swallowed similar to the string test "entero-test" and used for overnight treatment, allowing for a rapid release along the entire length of esophagus. In vitro drug release studies showed a target release of 1 mg/day of fluticasone. In vivo pharmacokinetic studies were carried out after deploying the string in a porcine model, and our results showed a high local level of fluticasone in esophageal tissue persisting over 1 and 3 days, and a minimal systemic absorption in plasma. The second device is a fluticasone-eluting 3D printed ring for local and sustained release of fluticasone in the esophagus. We designed and fabricated biocompatible fluticasone-loaded rings using a top-down, Digital Light Processing (DLP) Gizmo 3D printer. We explored various strategies of drug loading into 3D printed rings, involving incorporation of drug during the print process (pre-loading) or after printing (post-loading). In vitro drug release studies of fluticasone-loaded rings (pre and post-loaded) showed that fluticasone elutes at a constant rate over a period of one month. Ex vivo pharmacokinetic studies in the porcine model also showed high tissue levels of fluticasone and both rings and strings were successfully deployed into the porcine esophagus in vivo. Given these preliminary proof-of-concept data, these devices now merit study in animal models of disease and ultimately subsequent translation to testing in humans.

Abstract
In the absence of secondary causes, eosinophilic esophagitis (EoE) is a chronic, local, progressive, T-helper type 2 immune-mediated disorder characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. In the last 20 years, the incidence and prevalence of EoE have risen sharply, and the chances of encountering affected patients in clinics and endoscopy rooms have increased. Nevertheless, it is estimated that the mean diagnostic delay of EoE is 4-6 years in both children and adults. Unfortunately, the longer the disease stays unrecognized, the likelier it is for the patient to have persistent or increased esophageal eosinophilic inflammation, to complain of non-resolving symptoms, and to develop fibrotic complications. Early detection depends on the recognition of initial clinical manifestations that vary from childhood to adulthood and even among patients of the same age. The disease phenotype also influences therapeutic approaches that include drugs, dietary interventions, and esophageal dilation. We have herein reviewed epidemiologic, clinical, endoscopic, and histologic features and therapeutic options of EoE focusing on differences and similarities between children and adults that may certainly serve in daily clinical practice.

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
CONTEXT Treatment of eosinophilic esophagitis (EoE) is focused on dietary, pharmacologic, and endoscopic therapy options. Within the pharmacologic alternatives, topical corticosteroids are the most used, and a large number of studies evaluating their effectiveness have been published, requiring a new summary of evidence. OBJECTIVE To evaluate the histologic and clinical effectiveness of the use of corticosteroids in pediatric patients with a diagnosis of EoE. DATA SOURCES Cochrane Central Register of Controlled Trials, Medline, Embase, Science Citation Index Expanded, Conference Proceedings Citation Index-Science, Latin American and Caribbean Health Sciences Literature, and ClinicalTrials.gov (June 2019). STUDY SELECTION We selected randomized controlled trials assessing corticosteroids versus a placebo or dietary treatment of EoE in children. DATA EXTRACTION Methodologic quality of evidence was evaluated by using the Cochrane Collaboration's risk of bias tool and the Grading of Recommendations Assessment, Development, and Evaluation system. The primary outcomes were clinical and histologic improvement. RESULTS A total of 1655 studies were identified. Five studies were included (206 patients). Histologic response was 49.25% in the corticosteroids group and 4.16% in the placebo group (risk ratio 11.05 [confidence interval 3.8-32.15]; P < .0001). Symptomatic response was 33.6% in the corticosteroids group and 21.8% in the control group (risk ratio 1.62 [confidence interval 0.94-2.79]; P = .08). There were no major adverse effects. LIMITATIONS Heterogeneity of the diagnosis of EoE. CONCLUSIONS Our review revealed favorable results of corticosteroids versus placebo, mainly in histologic response. More studies are needed, by using validated clinical scores, to obtain more reliable results.

Abstract
BACKGROUND Swallowed topical steroids are a mainstay drug therapy for eosinophilic esophagitis (EoE), studies have demonstrated good histologic response, but with enormous discrepancy in clinical and endoscopic improvement. We conducted this meta-analysis to investigate the efficacy of topical steroids in EoE in histological, clinical and endoscopic improvement. METHODS Several databases were searched from inception to August 1, 2019 for randomized controlled trials (RCTs) comparing topical steroids with placebo for EoE in the short-term. The outcomes of interest mainly included basic characteristics of the studies, histologic, clinical, endoscopic response rate and adverse events. The results were pooled together using Reviewer Manager 5.3.5 software, and inconsistency was quantified using I2 statistics. RESULTS Nine studies were eventually selected. The results showed that topical steroids were effective in inducing histologic response compared with placebo for both complete (OR 35.82, 95% CI 14.98-85.64, P<0.0001; I2=0, P=0.72) and partial response (OR 28.44, 95% CI 8.56-94.47, P<0.0001; I2=70%, P=0.0009). Moreover, topical steroids were useful in gaining clinical response (OR 2.53, 95% CI 1.14-5.60, P=0.02; I2=60%, P=0.02) and endoscopic response (OR 3.51, 95% CI 1.47-8.36, P=0.005; I2=0, P=0.57). Generally, topical steroids are well tolerated. The most common adverse events are infections and infestations (59 cases). CONCLUSION Topical steroids were effective in inducing histological, clinical and endoscopic response in the short-term, and the adverse events were almost tolerable; however, we should interpret the result of clinical and endoscopic response with caution.

Abstract
The introduction of specific humanized monoclonal antibodies over the past 20 years has dramatically changed the treatment of allergic diseases. At present, 5 mAbs are licensed for treating moderate to severe allergic and eosinophilic asthma, atopic dermatitis, chronic spontaneous urticaria, chronic sinusitis with nasal polyps, and eosinophilic granulomatosis with polyangiitis. Given the high costs of biologics, understanding their cost-effectiveness is critical. As new biologics are developed and new indications are approved for existing biologics, the use of biologics for allergic diseases will increase. Conducting cost-effectiveness evaluations in parallel to efficacy and effectiveness trials will help patients, providers, payers, and policymakers in decision making.

Abstract
INTRODUCTION Eosinophilic Esophagitis (EoE) is an immune-mediated, chronic inflammatory disorder of the esophagus. Topical steroids have been used in the management of EoE for over 15 years. However, there are no Food and Drug Administration (FDA) approved drug therapies for EoE. AREAS COVERED This review discusses the current understanding of EoE and the role of topical steroids in the induction and maintenance of remission in patients with EoE. We performed a comprehensive review of the literature, summarized randomized control trials from 2006 to 2020, and provided a simplified management algorithm for EoE. EXPERT OPINION In patients with EoE, topical steroids are effective in inducing clinical and histologic remission. Formulations of topical steroids that maximize the exposure to esophageal mucosa have the highest efficacy. A majority of patients who achieve remission with topical steroids develop clinical and histologic relapse off therapy within a year. Current evidence suggests that maintenance therapy with long-term topical steroids decreases the risk of relapse and progression to fibrostenotic disease. While uncertainty over the dose and duration of maintenance topical steroids and their potential side effects exists, long-term maintenance therapy with topical steroids appears to be the way forward to improve long-term outcomes in patients with EoE.

Abstract
Eosinophilic esophagitis (EoE) is an emerging chronic local immune-mediated disease of the esophagus. Beside proton pump inhibitors and food-restriction-diets swallowed topical corticosteroids (STC) can be offered as a first line therapy according to current guidelines. This review describes the background and practical management of STCs in EoE. So far, mainly asthma inhalers containing either budesonide or fluticasone have been administered to the esophagus by swallowing these medications “off label”. Recently esophagus-targeted formulations of topical steroids have been developed showing clinicopathological response rates up to 85% - an orodispersible tablet of budesonide has been approved as the first “in label” medication for EoE in Europe in June 2018. Whereas it was shown that disease remission induction of EoE by STCs is highly effective, there is still a lack of data regarding long-term and maintenance therapy. However, current studies on STC maintenance therapy add some movement into the game.

Abstract
Eosinophilic esophagitis (EoE) is a non-immunoglobulin E mediated disorder that has been seen with increasing frequency over the past 25 years. Although the presentation varies per age group from vomiting and refusal to eat in infants and toddlers to abdominal pain and dysphagia in school-aged children, and food impaction and indigestion in adolescents and adults. Treatment options include proton-pump inhibitors, dietary avoidance, swallowed steroids, or a combination of these. Newer therapies with biologics show promise in early studies. Cow's milk is the most common food trigger of EoE across all age groups, followed by wheat and eggs. Different dietary avoidance strategies have been used, and help from a knowledgeable nutritionist is often key to success. Patients with EoE commonly have other baseline atopic disease. Clinicians who take care of patients who are atopic, therefore, should have a higher index of suspicion for EoE in patients with dysphagia. The goals of treatment are both a decrease in symptoms and normalization of esophageal histology. Eosinophilic gastrointestinal diseases are less common and less likely to respond to dietary therapies and/or avoidance. Pathogenesis seems to be different and may be more autoimmune mediated. Trialing dietary restrictions is certainly an option in this cohort of patients. For persistent symptoms and abnormalities, systemic medications have been used, although biologics may be used in the future. Additional studies are needed to determine which patients will respond to which therapies.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory disorder characterized by symptomatic esophageal dysfunction and an eosinophil-predominant inflammation of the esophagus. EoE arises from interaction between genetic and environmental factors. In pediatric patients, clinical manifestations vary depending on age, from a gastroesophageal reflux disease (GERD)-like condition to severe dysphagic symptoms. Upper endoscopy is considered the gold standard for diagnosis and monitoring of EoE; however, significant efforts are underway to identify noninvasive diagnostic tools and biomarkers to avoid repetitive invasive procedures. Therapeutic first-line options currently available for EoE are elimination diets, proton pump inhibitors (PPIs), and steroids. The aim of treatment is to improve clinical symptoms while obtaining mucosal healing and avoiding long-term complications. Dietary treatment options comprise different empiric diets or an exclusively amino acid formula. Despite the efficacy of diets, compliance is often challenging. PPIs and topical steroids represent the main pharmacological options for EoE, and both can induce and maintain remission. Topical steroids have been reported as more effective, but data on long-term safety remain insufficient for both these and PPIs. Endoscopic dilations are currently reserved for severe untreated fibrostenotic disease unresponsive to medical therapies. Several biologic agents are available but not yet approved for EoE.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. The incidence of EoE has increased substantially over the past two decades in Europe and North America. The natural course of EoE appears to be progressive with a high risk of stricture formation. The current European guideline recommend swallowed topical corticosteroids, proton-pump inhibitors or dietary intervention for initial and long-term treatment of EoE. Swallowed topical corticosteroids can be considered to be the best studied drug class in EoE, with more than 1000 patients enrolled in randomized clinical trials worldwide. In most of them, fluticasone or budesonide formulations have been used that were originally designed for asthma therapy, thus presumably suboptimal for EoE treatment. The new orodispersible budesonide tablet with effervescent properties is the first approved esophageal-targeted formulation specifically developed for the treatment of EoE, which has become available in many European countries. This article gives an overview of the evolution of topical corticosteroids in EoE and provides an update on recent data from large-scale multicenter trials exploring the efficacy and safety of the orodispersible budesonide tablet with effervescent properties in adult EoE patients.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory condition of the esophagus. Many new studies have been reported recently that describe EoE management. An expert panel was convened by the American Gastroenterological Association Institute and the Joint Task Force on Allergy-Immunology Practice Parameters to provide a technical review to be used as the basis for an updated clinical guideline. This technical review was developed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. Eighteen focused EoE management questions were considered, with 15 answered using the GRADE framework and 3 with a narrative summary. There is moderate certainty in the evidence that topical glucocorticosteroids effectively reduce esophageal eosinophil counts to <15 per high-power field over a short-term treatment period of 4-12 weeks, but very low certainty about the effects of using topical glucocorticosteroids as maintenance therapy. Multiple dietary strategies may be effective in reducing esophageal eosinophil counts to <15 per high-power field over a short-term treatment period, with moderate certainty for elemental diets, low certainty for empiric 2-, 4-, and 6-food elimination diets, and very low certainty that allergy-based testing dietary eliminations have a higher failure rate compared to empiric diet elimination. There is very low certainty for the effect of proton pump inhibitors in patients with esophageal eosinophilia. Although esophageal dilation appears to be relatively safe, there is no evidence that it reduces esophageal eosinophil counts. There is very low certainty in the effects of multiple other medical treatments for EoE: anti-interleukin-5 therapy, anti-interleukin-13 therapy, anti-IgE therapy, montelukast, cromolyn, and anti-TNF therapy.
