Abstract
Eosinophilic esophagitis (EoE) has evolved over the last three decades with a better understanding of the natural course of the disease. The prevalence of EoE is higher in Western countries with increasing reports of the incidence of EoE in the east. There is less data on EoE in India. We have noticed an increase in the number of cases of EoE diagnosed in our center over the last few years. In this study, all patients with high clinical suspicion of EoE were included and prospectively evaluated with endoscopic features and esophageal biopsies. Seventeen of 73 patients were diagnosed with EoE based on clinical, endoscopic and histopathologic features. One patient was lost to follow-up and 16 of the 17 patients were initiated on standard-of-care treatment and followed up for a minimum of four weeks. Treatment with proton pump inhibitors with six-food elimination diet is highly effective in most patients with a few patients requiring systemic steroids and endoscopic treatment. In conclusion, this study highlights that EoE exists in India with varied manifestations and a high index of clinical suspicion is necessary for diagnosis. It also emphasizes the need for increasing awareness of the entity of EoE, among both patients and doctors. Further, large-scale, multi-centric population-based studies are necessary to estimate the prevalence in our country.

Treatment Trends for Eosinophilic Esophagitis and the Other Eosinophilic Gastrointestinal Diseases: Systematic Review of Clinical Trials. Dig Liver Dis 2023; 55:208-222. [PMID: 35654734 DOI: 10.1016/j.dld.2022.05.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2022] [Revised: 05/09/2022] [Accepted: 05/13/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Eosinophilic gastrointestinal diseases (EGIDs) are chronic inflammatory disorders of the gut, including eosinophilic esophagitis (EoE), gastritis (EoG), duodenitis (EoD), gastroenteritis (EoGE), and colitis (EoC). Available treatments may be ineffective in some patients, and several clinical trials are investigating alternative treatments. AIM We performed a systematic review of clinical trials to illustrate EGIDs treatment research trends. METHODS We searched clinicaltrials.gov to identify studies investigating EGIDs treatment. For each trial we analysed relevant data, including therapeutic intervention, method of administration, study outcomes, and temporal trends. RESULTS For EoE, 66 studies were eligible: 26 testing topical corticosteroids (39.4%), 17 (25.8%) monoclonal antibodies, eight (12.1%) dietary measures, five (7.6%) immunomodulators, one (1.5%) esophageal dilation, and nine (13.6%) other medical treatment strategies. With regard to EoG, EoD, and EoGE, 10 studies were testing monoclonal antibodies (71.5%), one immunomodulators (7.1%), one dietary measures (7.1%), and two other treatments (14.3%). There were no trials for EoC. Ongoing studies on corticosteroids are focused on novel delivery systems, including viscous suspensions, orally disintegrating tablets, or capsules. Increased research on monoclonal antibodies was seen from 2018, with interleukin (IL)-4 receptor-α, IL-5 receptor-α, IL-5, IL-13, IL-15, and Siglec-8 as the targets. CONCLUSION Clinical trials on EGIDs are predominantly investigating corticosteroids or monoclonal antibodies. EGIDs therapeutic landscape will be trasnformed imminently.

Abstract
BACKGROUND Eosinophilic oesophagitis (EoE) is an increasingly common cause of dysphagia in both children and adults, as well as one of the most prevalent oesophageal diseases with a significant impact on physical health and quality of life. We have provided a single comprehensive guideline for both paediatric and adult gastroenterologists on current best practice for the evaluation and management of EoE. METHODS The Oesophageal Section of the British Society of Gastroenterology was commissioned by the Clinical Standards Service Committee to develop these guidelines. The Guideline Development Group included adult and paediatric gastroenterologists, surgeons, dietitians, allergists, pathologists and patient representatives. The Population, Intervention, Comparator and Outcomes process was used to generate questions for a systematic review of the evidence. Published evidence was reviewed and updated to June 2021. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system was used to assess the evidence and make recommendations. Two rounds of voting were held to assess the level of agreement and the strength of recommendations, with 80% consensus required for acceptance. RESULTS Fifty-seven statements on EoE presentation, diagnosis, investigation, management and complications were produced with further statements created on areas for future research. CONCLUSIONS These comprehensive adult and paediatric guidelines of the British Society of Gastroenterology and British Society of Paediatric Gastroenterology, Hepatology and Nutrition are based on evidence and expert consensus from a multidisciplinary group of healthcare professionals, including patient advocates and patient support groups, to help clinicians with the management patients with EoE and its complications.

Abstract
BACKGROUND Benralizumab is a monoclonal antibody targeting the IL-5 receptor used in the treatment of asthma. The use of benralizumab in other conditions is only emerging and could represent a therapeutic option for other eosinophil-associated diseases. Here, we report the case of a patient suffering from eosinophilic esophagitis and asthma who achieved histological remission of eosinophilic esophagitis (EoE) under benralizumab treatment for his asthma.
CASE SUMMARY Our patient was a 56-year-old white male with a history of eosinophilic esophagitis and severe asthma. After years of usual treatments, including topical steroids, biological treatment with mepolizumab, and standard asthma treatment, only poor control of both conditions was obtained. A control gastroscopy after the initiation of benralizumab showed complete histological remission of his EoE.
CONCLUSION Our case shows the effects of therapy with a novel agent not yet approved for this condition but for other diseases, with histological resolution of EoE after treatment. Complete clinical remission was not observed, which exemplifies the complex nature of EoE, its associated psychosomatic burden, and the chronification of the disease. Nevertheless, monoclonal antibodies targeting the Th2 response and, in our case, an IL5 receptor antagonist, achieved complete histological remission, which was not the case with an antibody against IL-5, which was also initiated to treat asthma.

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.

Formulations of Topical Steroids in Eosinophilic Esophagitis-Current Treatment and Emerging Possibilities. J Clin Med 2022; 11:jcm11051454.

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
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
BACKGROUND & AIMS Data evaluating efficacy of different doses of swallowed topical corticosteroids (STC) in the long-term management of eosinophilic esophagitis (EoE) are lacking. We assessed long-term effectiveness and safety of different STC doses for adults with EoE after achievement of histological remission. METHODS We performed a retrospective multicenter study at five EoE referral centers (US and Switzerland). We analyzed data on 82 patients with EoE in histological remission and ongoing STC treatment with therapeutic adherence of ≥75% (58 males; mean age at diagnosis, 37.2±14.4 years). Patients were followed for a median of 2.2 years (interquartile range [IQR], 1.0-3.8 years). We collected data from 217 follow-up endoscopy visits. The primary endpoint was time to histological relapse. RESULTS Histological relapse occurred in 67% of patients. Relapse rates were comparable in patients taking low dose (≤0.5 mg per day, n = 58) and high dose STC (>0.5 mg per day, n = 24) with 72 vs 54% (ns). However, histological relapse occurred significantly earlier with low dose STC (1.0 vs 1.8 years, P = .030). There was no difference regarding rates of and time to stricture formation for low vs high dose STC. Esophageal candidiasis was observed in 6% of patients (5% for low dose, 8% for high dose, ns). No dysplasia or mucosal atrophy was detected. CONCLUSION Histological relapse frequently occurs in EoE despite ongoing STC treatment regardless of STC doses. However, relapse develops later in patients on high dose STC without an increase in side-effects. Doses higher than 0.5 mg/day may be considered for EoE maintenance treatment, but advantage over lower doses appears to be small.

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
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
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
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) most often affects young patients of reproductive age, yet little is known about its effects during pregnancy. We examined the course of EoE during pregnancy, outcomes of pregnancies, and patient concerns related to pregnancy and EoE. METHODS We sent a survey that queried demographic and disease-specific characteristics as well as pregnancy-related topics to all 151 female patients treated at 2 EoE centers in Switzerland. We analyzed cross-sectional survey data. RESULTS Of 72 patients that returned the survey, we identified 20 patients that had at least 1 pregnancy and analyzed the data on 34 pregnancies. During pregnancy, improvement of dysphagia was reported in 56% (19/34) of all pregnancies, whereas deterioration was reported in 20% (7/34) of all pregnancies. After delivery, dysphagia returned to the pre-pregnancy level in 68% (13/19) of all pregnancies for patients with improvement of dysphagia and 57% (4/7) of all pregnancies for patients with deterioration of dysphagia during pregnancy. Esophagogastroduodenoscopy during pregnancy was required in less than 10% (3/34) of all pregnancies. Pregnancy-related complications occurred in 12% of pregnancies (4/34). The leading patient-reported concerns were fear of heritability (40% of patients, 8/20) and concerns of that use of medication would harm the fetus (30% of patients, 6/20). CONCLUSIONS Pregnancy affects the course of EoE, with improvement of symptoms reported in most patients. Dysphagia returned to the pre-pregnancy level following delivery. EoE has likely no negative effects on outcomes of pregnancies.

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 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
Introduction: The epidemiology of eosinophilic esophagitis (EoE) has increased rapidly to represent a common cause of chronic and recurrent esophageal symptoms. Current treatment options have limitations so the development of novel therapies is a matter of growing interest.Areas covered: This article provides an up-to-date discussion of current therapies and investigational options for EoE. Established anti-inflammatory treatments for EoE at present include dietary therapy, proton pump inhibitors and swallowed topic steroids, which should be combined with endoscopic dilation in case of strictures. Refractoriness, high recurrence rates, and need for long-term therapies have promoted the investigation of novel, esophageal-targeted formulas of topic corticosteroids, and monoclonal antibodies (including mepolizumab, reslizumab, QAX576, RPC4046, dupilumab, omalizumab, infliximab, and vedolizumab) for EoE, with some having been demonstrated as effective and safe in the short term. Several additional promising therapies are also discussed.Expert opinion: Several therapeutic targets have shown efficacy and will be approved to treat EoE, especially corticosteroid-sparing options and those for patients with multiple Th2-associated diseases. Personalized therapeutic strategies for initial and maintenance treatments of EoE must be rationally designed, to reduce the burden of disease and answer meaningfully the needs of all stakeholders involved in EoE.

Abstract
PURPOSE OF REVIEW With a globally aging population, dysphagia is a growing health concern among elderly. Increasing reflux disease has contributed to an increased prevalence of dysphagia from peptic strictures and esophageal cancer. Dysphagia can lead to malnutrition and aspiration pneumonia, causing considerable morbidity and mortality. This review article focuses on recent advances in the approach and management of esophageal dysphagia. RECENT FINDINGS Endoscopic functional luminal imaging probe is a novel test that complements upper endoscopy, esophagram, and esophageal manometry for evaluation of esophageal dysphagia. Opioid induced esophageal dysfunction (OIED) is an emerging clinical entity that can mimic achalasia. Strictures refractory to dilation can be treated with intralesional steroid injections, electrosurgical incision, or esophageal stents. Peroral endoscopic myotomy (POEM) is gaining in popularity for treatment of achalasia and other spastic disorders of esophagus. Treatment of esophageal dysphagia may include proton pump inhibitors, endoscopic dilation, or surgery and requires a personalized approach based on risks and benefits. POEM is a valuable therapy for achalasia, but further studies are needed to evaluate its use, and other alternatives, for treatment of OIED and spastic esophageal disorders.

Abstract
Formerly considered a rare disorder, eosinophilic esophagitis (EoE) has emerged as a leading cause of feeding problems in children and an increasingly recognized cause of dysphagia and food impaction in adults. Our understanding of EoE and its complex interplay with gastro-esophageal reflux disease (GERD) has evolved over the past decade and culminated in the introduction of proton pump inhibitor (PPI) responsive EoE as a distinct entity which has added to this complexity. It is now clear that this entity is on the same spectrum as the original EoE, and that PPIs should be considered as part of treatment protocol and should not be recommended as a diagnostic tool. As such, removing the PPI trial from the diagnostic algorithm has been encouraged recently. Recent guidelines and reviews thoroughly address various aspects in EoE pathogenesis and diagnostic workup as well as management endpoints, treatment options and novel therapies. However, despite the recent extensive study and the advances in our knowledge of this disease, unmet needs and pitfalls in diagnostic workup and management of these patients are still to be clarified and will be under focus in this review.

Abstract
Background Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory disorder and represents the leading cause of food impaction. The pathogenesis of EoE is the result of an interplay between genetic, environmental and host immune system factors. New therapeutic approaches for EoE have been proposed. In this manuscript we review the current evidence regarding EoE management in pediatric age, with a particular focus on new findings related to the efficacy and safety of monoclonal antibodies. Main body Conventional therapies have failed in treating some patients with EoE, which then requires aggressive procedures such as esophageal dilatation. The most effective available medical therapy for EoE is swallowed topic corticosteroids (fluticasone propionate and budesonide), which have two main drawbacks: they are related to well-known adverse effects (especially in the paediatric population), and there are not enough long-term data to confirm that they are able to reverse the remodelling process of the esophageal mucosa, which is the major cause of EoE symptoms (including dysphagia, abdominal pain, nausea, obstruction, perforation and vomiting). The monoclonal antibodies appear to be an interesting therapeutic approach. However, the studies conducted until now have shown substantial histological improvement not coupled with significant clinical improvements and no significant relationship between a decreasing number of eosinophils and clinical symptoms, highlighting the importance in the pathogenesis of EoE of cells such as T-helper cells, mast cells, B cells, epithelial cells and natural killer cells. Conclusions Monoclonal antibodies targeting a signal involved in the pathogenesis of EoE may not break the complex self-propagating inflammatory activation responsible for perpetuation of the inflammatory response and the development of symptoms and complications. We speculate that combined biological therapies targeting more than one molecule or cell may provide better results, with conventional therapies potentially enhancing the effects of antibodies. However, further studies should aim to find the best therapeutic approach to target the cells involved in the remodelling process and to reverse the histological changes in this complex clinical condition.

Abstract
Eosinophilic esophagitis (EoE) is an immune-mediated disease triggered by food antigens for which dietary elimination treatment can induce and sustain histologic remission. Our review aims to describe the state of the art regarding dietary treatment of EoE, highlighting a number of areas of controversy related to dietary therapy in EoE, including novel modalities for determining food triggers, making the empiric dietary elimination process more efficient, issues of cross-contamination and "dosing" of how much food to avoid or add back, costs and effects on quality of life, long-term efficacy, and the risk of developing immediate IgE-type reactions after initial dietary elimination. Elemental formulas, empiric elimination diets, and targeted allergy test-directed elimination diets are well-described treatments for EoE. Although elemental diets are most efficacious, their clinical use is limited by cost and the palatability of an exclusively liquid diet. While empiric elimination is less effective than elemental formula-based diets, they are more easily implemented and often sustainable. Since the comparative effectiveness of elimination diets with proton-pump inhibitors and swallowed topical steroids remains unknown, there are multiple areas to address with future research.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, allergen-driven inflammatory esophageal disease characterized by predominantly eosinophilic inflammation leading to esophageal dysfunction. Recent efforts to understand EoE have increased our knowledge of the disease. Areas covered: Multiple cells, molecules, and genes interplay with early life environmental factors in the pathophysiology of EoE to converge in the esophageal epithelium at the center of disease pathogenesis. Epithelial cells constitute a mayor cytokine source for TSLP and Calpain-14; an impaired epithelial barrier function allowing penetration of food and microbiota-derived antigens is involved in triggering and maintaining inflammation. Eosinophil and mast cell-derived products, including TGFβ, together with IL-1β and TNFα, promote epithelial mesenchymal transition in EoE, contributing to tissue remodeling by synthetizing and depositing extracellular matrix in subepithelial layers. This article aims to provide a state-of-the-art update on the pathophysiology of EoE applied to clinical practice, and latest research and developments with potential interest to improve the diagnosis and treatment of patients with EoE are revised. Expert commentary: Preliminary approaches have provided promising results toward incorporating minimally invasive methods for patient diagnosis and monitoring in clinical practice. Early diagnosis and optimized therapies will allow for personalized medicine in EoE.

Abstract
BACKGROUND Well informed patients who are in cohesive partnership with physicians and who have realistic expectations towards therapy are more likely to be adherent, which results in better disease control. AIM To assess which therapy goals adults with eosinophilic oesophagitis consider relevant. METHODS Following refinement during three focus groups, a study brochure and questionnaire were sent to 148 patients. Patients ranked the importance (five levels) of short-term (in the next 3 months) and long-term (≥1 year) treatment effect on symptoms, quality of life (QoL), histologically-detected inflammation and fibrosis, endoscopically-detected inflammation, and stricture formation as well as achieving histological remission while asymptomatic. Patients' characteristics associated with treatment goals were identified using logistic regression. RESULTS Of 109 respondents (mean age 43 years), 85 were men. Over 90% chose symptoms and QoL improvement as important short- and long-term therapy goals. A greater proportion attributed more importance to long-term reduction in endoscopic (90% vs 73%, P < 0.001) and histological (81% vs 62%, P = 0.002) inflammation, and histologically-detected fibrosis (79% vs 64%, P = 0.018) when compared to short-term reduction in these features. Patients (88%) ranked achieving histological remission while being asymptomatic as important. Gender, therapy use, education level, QoL, symptom severity, and history of dilation were associated with patients' choice of treatment goals. CONCLUSIONS Patients attributed most importance to improvement in symptoms and QoL. Reduction in biological activity was judged less important, but more relevant in the long- compared to the short-term.

Eosinophilic Esophagitis: Review and Update. Front Med (Lausanne) 2018; 5:247. [PMID: 30364207 PMCID: PMC6192373 DOI: 10.3389/fmed.2018.00247] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 08/15/2018] [Indexed: 12/13/2022] Open
Abstract
Background: Eosinophilic esophagitis (EoE) was first described in the 1990s, showing an increasing incidence and prevalence since then, being the leading cause of food impaction and the major cause of dysphagia. Probably, in a few years, EoE may no longer be considered a rare disease. Methods: This article discusses new aspects of the pathogenesis, symptoms, diagnosis, and treatment of EoE according to the last published guidelines. Results: The epidemiological studies indicate a multifactorial origin for EoE, where environmental and genetic factors take part. EoE affects both children and adults and it is frequently associated with atopic disease and IgE-mediated food allergies. In patients undergoing oral immunotherapy for desensitization from IgE-mediated food allergy the risk of developing EoE is 2.72%. Barrier dysfunction and T-helper 2 inflammation is considered to be pathogenetically important factors. There are different patterns of clinical presentation varying with age and can be masked by adaptation habits. Besides, symptoms do not usually correlate with histologic disease activity. The diagnostic criteria for EoE has evolved but mainly requires symptoms of esophageal dysfunction with histologic evidence of a peak value of at least 15 eosinophils per high-power field. Endoscopies have to be repeated in order to diagnose, monitor, and treat EoE. Treatment of EoE can be started either by drugs (PPIs and topical corticosteroids) or elimination diets. The multistage step-up elimination diet management approach of EoE is promising. Endoscopic dilation is used for patients with severe dysphagia/food impaction with inadequate response to anti-inflammatory treatment. Conclusions: Research in recent years has contributed to a better understanding of EoE's pathogenesis, genetic background, natural history, allergy workup, standardization in assessment of disease activity, evaluation of minimally invasive diagnostic tools, and new therapeutic approaches. However, several unmet needs are to be solved urgently, as finding a non-invasive disease-monitoring methods and biomarkers for routine practice, the development or new therapies, novel food allergy testing to detect triggering foods, drug, and doses required for initial therapy and safety issues with long-term maintenance therapy, amongst others. Besides, multidisciplinary management units of EoE, involving gastroenterologists, pediatricians, allergists, pathologists, dietitians, and ENT specialists are needed.

Abstract
IL‐5 is an important cytokine for priming and survival of mature eosinophils and for proliferation and maturation of their progenitors. Hence, IL‐5(Rα) targeting will be increasingly used in diseases where eosinophils are the key immune effector cells such as eosinophilic asthma (EA), hypereosinophilic syndrome (HES), eosinophilic esophagitis (EE), and eosinophilic granulomatosis with polyangiitis (EGPA). Therefore, several neutralizing monoclonal antibodies directed against IL‐5 (mepolizumab and reslizumab) and its receptor IL‐5Rα (benralizumab) have found or will find their way to the clinic. While the clinical effect of these drugs has been extensively investigated and reviewed, the understanding of the underlying immunological and hematological mechanisms remains less clear. This review will discuss the translational outcomes of treatment with these monoclonal antibodies in humans to shed light on the mechanisms underlying the main immunological and hematological findings from these clinical trials in humans.

Abstract
Eosinophilic gastrointestinal disorders are a set of conditions with a wide range of clinical manifestations and treatment modalities. The disorders are suspected to result from an abnormal inflammatory response to allergen (s), and individuals may develop a relapsing or chronic disease, if the allergen is not eliminated. Mechanisms of disease pathogenesis, including the humoral immune response, need to be fully elucidated. A variety of therapies are used, although there is a lack of well-defined randomized, prospective studies. Other therapeutic options are needed as the current treatments have potential concerns; elimination diets may impair a child's quality of life, and corticosteroids have adverse risks with long-term use. We review what is known about nonesophageal eosinophilic gastrointestinal disorders, and discuss research investigations which need to be conducted to facilitate diagnosis and enhance treatment methods.

Abstract
The eosinophilic gastrointestinal diseases (EGIDs) represent disorders of the gastrointestinal (GI) tract that result from the local infiltration and aberrant activity of eosinophils and other immune cells. Eosinophilic esophagitis (EoE) is the most well-characterized EGID and is defined by the presence of intraepithelial eosinophils in the esophagus (≥15 eosinophils per high-powered field) and clinical symptoms associated with esophageal dysfunction. The other EGIDs are rare and lack strong data regarding pathogenesis and management. The incidence and prevalence of EoE are increasing, and EoE is now a major cause of upper GI morbidity. Management is multidisciplinary, with collaboration between gastroenterologists, allergists, pathologists, and dieticians, and is aimed at amelioration of symptoms and prevention of long-term complications such as esophageal stricture. Treatment options for EoE include proton pump inhibitors, swallowed topical corticosteroids, and elimination diets. Esophageal dilation is used when esophageal strictures or fibrostenotic changes are present. Additional therapies targeting eosinophils and other mediators of Th2 inflammation are under development and are promising. Treatment options for other EGIDs typically involve corticosteroids or dietary elimination.

Abstract
GOALS In order to provide a comparative evaluation of available pharmacologic treatments for eosinophilic esophagitis (EoE), we conducted a network meta-analysis. BACKGROUND A variety of pharmacologic treatments for EoE have been reported, however there exists a paucity of direct comparisons. STUDY We searched randomized controlled trials using MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials database through December 2014. Studies were analyzed using a random-effects network meta-analysis to identify the most effective therapy. Subgroup analysis was performed among studies that excluded gastroesophageal reflux disease or proton-pump inhibitor responsive esophageal eosinophilia, and also among pediatric and adult populations. The ranking probability for the efficacy of each treatment was analyzed. Consistency of the included randomized controlled trials was checked by applying inconsistency and node-splitting models. RESULTS Eleven studies of a total of 456 patients were identified. Six pharmacologic treatments (budesonide suspension and viscous, fluticasone, prednisone, esomeprazole, and mepolizumab) and placebo were included in our analysis. Meta-analysis showed superiority of budesonide viscous, budesonide suspension, and fluticasone over placebo. Network meta-analysis demonstrated the rank order of efficacy as budesonide viscous, esomeprazole, prednisone, budesonide suspension, fluticasone, mepolizumab, and placebo. The results were consistent from the inconsistency model analysis and node-splitting analysis. Subgroup analysis demonstrated prednisone, budesonide suspension, and esomeprazole were the most effective when network meta-analyses were performed among studies that excluded gastroesophageal reflux disease or proton-pump inhibitor responsive esophageal eosinophilia, and among pediatric and adult populations, respectively. CONCLUSIONS On the basis of this network meta-analysis, viscous budesonide was shown to be the most effective pharmacologic therapy for EoE among the reported pharmacologic treatments.

Abstract
UNLABELLED Eosinophilic esophagitis (EoE) is a unique form of non-IgE-mediated food allergy characterized by esophageal eosinophilic infiltration that commonly causes dysphagia and food impaction in children and adolescents. Assessing the efficacy of dietary restrictions or drug therapies to achieve clinical and histologic resolution of EoE through randomized controlled trials and meta-analyses has resulted in new evidence-based guidelines. Avoiding food triggers is the only therapy targeting the cause of the disease. None of the currently available food allergy tests adequately predict food triggers for EoE. Exclusively feeding with an amino acid-based elemental diet and empiric six-food elimination diet (avoiding the six foods most commonly related with food allergy) has consistently provided the best cure rates, but their high level of restriction and need for multiple endoscopies are deterrents for implementation. Simpler and less restrictive empirical methods, like a four-food (milk, gluten-containing cereals, egg, legumes) or a two-food (milk and gluten) elimination diet, show encouraging results. Proton pump inhibitors are currently a first-line treatment, achieving histological remission and improvement of symptoms in 54.1 and 64.9% of pediatric EoE patients, respectively. The efficacy of topical corticosteroids in EoE assessed in several trials and summarized in meta-analyses indicates that budesonide and fluticasone propionate are significantly superior to placebos, both in decreasing eosinophil mucosal infiltration and in relieving symptoms. Owing to differences in drug delivery, viscous budesonide formulas seem to be the best pharmacological therapy for EoE. CONCLUSION Applying evidence-based therapies and a practical management algorithm provide an effective control of EoE. What is Known: • Eosinophilic esophagitis (EoE) now constitutes the main cause of dysphagia and food impaction in children, adolescents, and young adults. • Its chronic course and frequent progression to subepithelial fibrosis leading to strictures and narrow-caliber esophagus indicate the need for treatment. What is New: • Therapeutic goals in children with EoE include resolution of esophageal symptoms, to cure esophageal inflammation (mucosal healing) and restore a proper esophageal caliber in case of fibrostenotic endoscopic findings. Avoiding iatrogenic drug effects and nutritional deficiencies, as well as maintaining an adequate quality of life, is also essential. • Novel evidence-based guidelines, endorsed by several European scientific societies, incorporate recent advances in knowledge from several randomized controlled trials and systematic reviews to provide the best standard of care to pediatric patients, by following simple management algorithms.

Abstract
Eosinophilic esophagitis (EoE) is a new disease. It is caused by a T-helper type 2 cell response to food antigens in contact with the esophageal mucosa. Although no single feature defines EoE, a constellation of compatible demographic, clinical, endoscopic, and histologic findings establish the diagnosis. Children present with symptoms and endoscopic patterns characteristic of inflammation, whereas adolescents and adults have manifestations of fibrosis and gross esophageal strictures. Clinical and endoscopic scoring systems have helped to standardize diagnosis. There is controversy in EoE research over the optimal endpoint for treatment. Although the most common endpoint is a reduced number of eosinophils in biopsies, changes in symptoms and endoscopic features are becoming important targets of therapy. We should improve our understanding of EoE progression and the need for maintenance therapy, and continue development of diagnostic tools that avoid endoscopy and biopsy analyses to more easily monitor disease activity.

Abstract
Eosinophilic esophagitis (EoE) is defined as a chronic, immune-medicated or antigen-mediated, esophageal disease, characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation. Food allergens are identified in most patients. Treatment strategies include elimination diets, drugs, and esophageal dilation. This article focuses on pharmacologic treatment. Currently, there is no pharmacologic treatment that has been approved by regulatory authorities. Established pharmacologic options to treat EoE include proton pump inhibitors and swallowed topical steroids. Several biologic therapies are currently under evaluation and some of them have shown promising results in improving biologic endpoints and patient-reported outcomes.

Abstract
Eosinophilic esophagitis (EoE) has arisen as a common disorder in current clinical and endoscopic gastroenterology practice. Areas covered: A comprehensive review of the literature to summarize and update different aspects related with the use of endoscopy in the diagnostic workout and treatment of pediatric and adult EoE patients is conducted. Expert commentary: Endoscopic features in EoE are frequently subtle, so were inadverted in some initial reports of the disease. Literature has described a wide number of EoE-associated features, systematized in the EREFS classification, which standardized the grade and severity of exudates, rings, edema, furrows, and strictures. The insufficient reliability of these features to predict eosinophilic inflammation still makes biopsies essential in diagnosing or monitoring EoE. EoE causes half of the food impactions requiring endoscopy; food impaction leads to EoE diagnosis in up to half of cases. Long term consequences of EoE include esophageal remodeling leading to strictures and narrowing, thus impairing symptoms and needs dilation. Recognizing the risks from dilation in EoE required carrying out a safe technique to avoid the high complication rate reported in the early literature. Endoscopic dilation should be considered in patients with esophageal narrowing and dysphagia/food impaction unresponsive to diet or drugs-based anti-inflammatory treatment.

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
BACKGROUND Topical corticosteroids or six-food elimination diet is recommended as initial therapy for eosinophilic esophagitis (EoE). AIMS We aimed to summarize published manuscripts that report outcomes of these therapies for EoE. METHODS We performed a systematic review in MEDLINE, Web of Science, and Embase of published manuscripts describing topical fluticasone, topical budesonide, and six-food elimination diet as therapies for EoE. We conducted meta-analysis of symptom improvement and the change in peak mucosal eosinophil count, with heterogeneity between studies examined with meta-regression analysis. RESULTS Systematic review yielded 51 articles that met inclusion criteria. Summary histologic response rates were 68.3% [95% prediction limits (PL) 16.2-96.0%] for fluticasone, 76.8% (95% PL 36.1-95.1%) for budesonide, and 69.0% (95% PL 31.9-91.4%) for six-food elimination diet. Corresponding decreases in eosinophil counts were 37.8 (95% PL 19.0-56.7), 62.5 (95% PL 125.6 to -0.67, and 44.6 (95% PL 26.5-62.7), respectively. Symptom response rates were 82.3% (95% PL 68.1-91.1%), 87.9% (95% PL 42.7-98.6%), and 87.3% (95% PL 64.5-96.3%), respectively. Meta-regression analyses decreased the initially large estimate of residual heterogeneity and suggested differences in histologic response rate associated with study populations' baseline eosinophil count and age. CONCLUSIONS The literature describing topical corticosteroids and six-food elimination diet consists of small studies with diverse methods and population characteristics. Meta-analysis with meta-regression shows initial histologic and symptomatic response rates on the same order of magnitude for topical corticosteroids and six-food elimination diet, but heterogeneity of study designs prevents direct comparison of modalities.

Abstract
Over the past decades eosinophilic esophagitis (EoE) has been increasingly diagnosed, and significant progress has been made in our understanding of its pathophysiology. As EoE cannot be cured yet, treatment goals are suppression of disease activity and symptoms as well as the prevention of progression to a more severe disease phenotype. Disease-modifying treatment options can be divided into dietary therapy and immunosuppressive medications, of which topical steroids have been most investigated, yet are still prescribed off-label. In this review, we will summarize recent advances in our understanding of EoE and discuss the mechanisms of action of current treatment options, with emphasis on the role of the esophageal epithelial barrier and the effects of proton-pump inhibitors in the management of patients with EoE.

Abstract
Since first characterized in 2 small case series in the early 1990s, eosinophilic esophagitis (EoE) has emerged as a commonly identified cause of esophageal symptoms in children and adults.1,2 Although several highly effectively dietary, pharmacologic, and endoscopic therapies have been reported, none is currently approved by either the US Food and Drug Administration (FDA) or European regulatory authorities. Evolving diagnostic criteria have challenged drug development, in particular the recognition of complex interactions with the most prevalent esophageal disorder, gastroesophageal reflux disease (GERD). Heterogeneity in the clinical presentations of affected children and adults has created difficulties with uniform inclusion criteria and the development of disease-specific, patient-reported outcome (PRO) instruments. Furthermore, controversies regarding the appropriate therapeutic endpoints of EoE have impeded the design of clinical trials. Despite these obstacles, collaborative efforts by investigators, industry, the FDA, and patient advocacy groups have resulted in substantial progress in drug development in EoE over the past 2 decades.3 The purpose of this article is to summarize discussions on EoE based on the 2016 Drug Development Conference sponsored by the Center for Diagnostics and Therapeutics of the American Gastroenterological Association.

Abstract
Background: Topical corticosteroids have proven efficacy in the treatment of eosinophilic esophagitis (EoE) and are considered the cornerstone of therapy. Objective: To evaluate the effect of topical beclomethasone dipropionate (BDP) therapy on clinical outcomes, esophageal eosinophilia, and other markers of inflammation in patients with EoE. Methods: Nine subjects with a biopsy-proven diagnosis of EoE were enrolled. In a cross-over design, the subjects were randomly assigned to a sequence of BDP and placebo. Treatment periods were 8 weeks, with a 4-week washout period. The subjects had endoscopic biopsies and blood tests at baseline and after each treatment period. They were instructed to maintain a diary of symptoms. Immuno-histochemical studies were performed for interleukins IL-4, IL-5, IL-13, granulocyte-macrophage colony-stimulating factor (GM-CSF), and transforming growth factor (TGF) beta. Reverse transcription polymerase chain reaction was performed for IL-3, IL-4, IL-5, IL-10, IL-13, IL-17F, IL-25, IL-33, chemokine ligands (CCL)2, CCL5, CCL11, GM-CSF, and TGF-beta levels. The mast cell tryptase (MCT) level was measured in esophageal tissues. Results: BDP led to a significantly larger decrease in esophageal eosinophilia compared with placebo, but there was no significant change in peripheral eosinophilia and high-sensitivity C-reactive protein between the two groups. The study was not powered enough for us to report a significant improvement in clinical symptoms. There was a significant decrease in tissue IL-13 and MCT levels from baseline to the end of treatment between the treatment and placebo groups. Mean fold decreases in cytokine expression between the baseline and treatment groups were observed for IL-17F, IL-25, CCL2, and CCL5. Conclusion: Treatment with topical BDP was associated with significant decrease in esophageal eosinophilia, MCT and IL-13. BDP is a potential alternative to fluticasone propionate and budesonide for treatment of EoE. Larger studies are needed to validate these findings.

Cost Utility Analysis of Topical Steroids Compared With Dietary Elimination for Treatment of Eosinophilic Esophagitis. Clin Gastroenterol Hepatol 2017; 15:841-849.e1. [PMID: 27940272 PMCID: PMC5440206 DOI: 10.1016/j.cgh.2016.11.032] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 11/17/2016] [Accepted: 11/22/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Topical corticosteroids or dietary elimination are recommended as first-line therapies for eosinophilic esophagitis, but data to directly compare these therapies are scant. We performed a cost utility comparison of topical corticosteroids and the 6-food elimination diet (SFED) in treatment of eosinophilic esophagitis, from the payer perspective. METHODS We used a modified Markov model based on current clinical guidelines, in which transition between states depended on histologic response simulated at the individual cohort-member level. Simulation parameters were defined by systematic review and meta-analysis to determine the base-case estimates and bounds of uncertainty for sensitivity analysis. Meta-regression models included adjustment for differences in study and cohort characteristics. RESULTS In the base-case scenario, topical fluticasone was about as effective as SFED but more expensive at a 5-year time horizon ($9261.58 vs $5719.72 per person). SFED was more effective and less expensive than topical fluticasone and topical budesonide in the base-case scenario. Probabilistic sensitivity analysis revealed little uncertainty in relative treatment effectiveness. There was somewhat greater uncertainty in the relative cost of treatments; most simulations found SFED to be less expensive. CONCLUSIONS In a cost utility analysis comparing topical corticosteroids and SFED for first-line treatment of eosinophilic esophagitis, the therapies were similar in effectiveness. SFED was on average less expensive, and more cost effective in most simulations, than topical budesonide and topical fluticasone, from a payer perspective and not accounting for patient-level costs or quality of life.

Abstract
BACKGROUND & AIMS Pharmacologic treatment of eosinophilic esophagitis (EoE) is limited to off-label use of corticosteroids not optimized for esophageal delivery. We performed a randomized, controlled phase 2 trial to assess the ability of budesonide oral suspension (BOS), a novel muco-adherent topical steroid formulation, to reduce symptoms and esophageal eosinophilia in adolescents and adults with EoE. METHODS In this multicenter, randomized, double-blind, placebo-controlled, parallel-group trial, 93 EoE patients between the ages of 11 and 40 years with dysphagia and active esophageal eosinophilia were randomized to receive either BOS 2 mg or placebo twice daily for 12 weeks. Co-primary outcomes were change in Dysphagia Symptom Questionnaire (DSQ) score from baseline, and proportion of patients with a histologic response (≤6 eosinophils/high-power field) after treatment. Endoscopic severity scores and safety parameters were assessed. RESULTS At baseline, mean DSQ scores were 29.3 and 29.0, and mean peak eosinophil counts were 156 and 130 per hpf in the BOS and placebo groups, respectively. After treatment, DSQ scores were 15.0 and 21.5, and mean peak eosinophil counts were 39 and 113 per high-power field, respectively (P < .05 for all). For BOS vs placebo, change in DSQ score was -14.3 vs -7.5 (P = .0096), histologic response rates were 39% vs 3% (P < .0001), and change in endoscopic severity score was -3.8 vs 0.4 (P < .0001). Adverse events were similar between groups. CONCLUSIONS Treatment with BOS was well tolerated in adolescent and young adult patients with EoE and resulted in improvement in symptomatic, endoscopic, and histologic parameters using validated outcome instruments.

Abstract
BACKGROUND Eosinophilic oesophagitis (EoE) is a chronic disease, driven by food allergens. Elemental diets are effective for the management of children with EoE, but studies on the effect of elemental diets in adults are scarce and poor palatability challenges dietary adherence. AIM To assess the effects of an elemental diet (Neocate, Nutricia, Utrecht, the Netherlands) on the inflammation, symptoms and endoscopic signs in adult EoE patients. METHODS In this prospective study, 21 patients with active EoE, confirmed by biopsies showing ≥15 eosinophils per microscopic high power field (HPF) and symptoms of oesophageal dysfunction were included. Patients underwent endoscopy before and 4 weeks after diet. Histological disease activity (peak eosinophil count/HPF), and endoscopic signs were scored by physicians. Symptoms and adherence to the diet were evaluated by questionnaires. Serum total IgE levels and total eosinophil counts were determined and the expression of inflammatory cytokines was analysed by qPCR. RESULTS In total, 17 (81%) of the patients completed the diet, of whom 12 (71%) showed complete histological response (≤15 eosinophils/HPF) and 4 (24%) showed partial histological response (≥50% reduction of baseline eosinophil count). Peak eosinophil counts decreased significantly after the diet from 40 to 9 per HPF (P ≤ 0.001). A marked improvement in endoscopic signs was observed. Symptoms decreased significantly in all subjects, and 15 patients (88%) became completely asymptomatic (P ≤ 0.001). In 14 patients (82%), blood eosinophil count and serum IgE decreased (P ≤ 0.05). CONCLUSION Elemental diet reduces eosinophilic inflammation and induces clinical remission in adult patients with eosinophilic oesophagitis.

Abstract
OBJECTIVES Eosinophilic esophagitis (EoE) is an immune-mediated allergic disease characterized by progressive esophageal dysmotility and fibrotic stricture associated with chronic esophageal fibroblast activation. It remains unknown how esophageal fibroblasts respond to EoE-relevant matrix stiffness or inflammatory cytokines. METHODS Immunofluorescence was used to evaluate α-smooth muscle actin (α-SMA) expression in endoscopic esophageal biopsies. Primary esophageal fibroblasts from adult and pediatric patients with or without EoE were exposed to transforming growth factor (TGF)β to determine gene expression, collagen-matrix contractility, and cytoskeletal organization. The influence of matrix stiffness upon fibroblast behavior was assessed on the engineered surface of polyacrylamide gels with varying stiffness. Fibroblast traction forces were measured using microfabricated-post-array-detectors. RESULTS EoE esophageal fibroblasts had enhanced α-SMA expression. TGFβ not only stimulated enhanced fibroblast-specific gene expression but also promoted fibroblast-mediated collagen-matrix contraction, despite disease state or age of patients as the origin of cells. Unlike conventional monolayer cell, culture conditions using plastic surface (1 GPa) that activates fibroblasts constitutively, our engineered platforms recapitulating physiologically relevant stiffness (1-20 kPa) revealed that matrix stiffness defines the extent of α-SMA expression, intracellular collagen fibril organization, SMAD3 phosphorylation, and fibroblast traction force. CONCLUSIONS Matrix stiffness may critically influence TGFβ-mediated gene expression and functions of esophageal fibroblasts ex vivo independent of age and disease conditions. These findings provide a novel insight into the pathogenesis of fibrostenotic disease in EoE.

Abstract
BACKGROUND Periostin is highly expressed in eosinophilic oesophagitis (EoE), but has not been extensively studied as a non-invasive biomarker. AIM To assess whether serum periostin distinguished EoE from controls at baseline, had utility for monitoring treatment response, or was associated with IL-13 levels. METHODS This was a sub-analysis of a prospective cohort study of adults undergoing out-patient upper endoscopy. Incident cases of EoE were diagnosed per consensus guidelines. Controls were subjects with either GERD or dysphagia without EoE. EoE patients were treated with swallowed/topical steroids and had repeat endoscopy/biopsy. Serum periostin levels for cases and controls were compared at baseline, and pre/post-treatment levels were compared for cases. Serum IL-13 and tissue expression of periostin were also assessed. RESULTS A total of 61 incident EoE cases and 87 controls were analysed. Despite a marked increase in tissue periostin expression in cases, the median baseline serum periostin level was only slightly higher in cases than controls (22.1 ng/mL vs. 20.7; P = 0.04); there was no change in post-treatment levels. There was also no difference in serum periostin for cases by histologic response or atopic status. There was a strong trend towards higher serum IL-13 levels in cases in the highest periostin quartile (57.1 pg/mL vs. 2.6; P = 0.07). CONCLUSIONS Serum periostin levels were similar in cases and controls, and there were no changes post-treatment. Given elevated IL-13 levels in the EoE patients with the highest periostin levels, future studies could explore periostin as a biomarker in EoE, perhaps in the setting of anti-IL-13 therapy.

Abstract
BACKGROUND Elimination diets and high-dose proton pump inhibitors (PPI) are advocated as first-line treatments in patients with eosinophilic oesophagitis (EoE). AIM To record the treatment outcome for patients with EoE prospectively managed according to a clinical algorithm. METHODS Patients with oesophageal eosinophilia commenced esomeprazole 40 mg twice daily for 8 weeks. Those in histological remission were re-classified as PPI-responsive oesophageal eosinophilia. Nonresponders were offered the 6-food elimination diet with a PPI, or topical budesonide monotherapy (1 mg orally twice daily as an aqueous gel). Once disease control was achieved remission was reassessed at 3 months (all modalities) and an additional 6 months (diet group). RESULTS Of 107 patients who completed 8 weeks of PPI, 25 (23%) were PPI-responsive. 56 of 81 (69%) of patients with EoE chose the elimination diet with PPI. 29 (52%) had complete remission, 23 completed dietary reintroduction and food triggers were identified in 20 (36%). 25 chose budesonide with 23/25 (92%) responding. Remission was sustained in >85% of patients at 3 months with all treatment modalities. At 9 months, only 10/18 (55%) of patients who responded to the elimination diet with PPI remained complaint and sustained remission. CONCLUSIONS Many patients previously diagnosed with EoE will respond to PPI. Initial response >50% is possible with the elimination diet plus PPI, but many will fail to undergo food reintroduction, or will cease the diet and relapse, resulting in only one in four patient sustaining remission at 9 months. Budesonide is very effective short term, but longer term study is needed.

Abstract
BACKGROUND In eosinophilic esophagitis (EoE), dysphagia, which might reflect esophageal dysmotility, is the most common symptom. High-resolution manometry (HRM) has become widely accepted for evaluating esophageal motility disorders, but to date has been sparsely examined in EoE patients, particularly under therapy. The aim of this study was to evaluate HRM in symptomatic EoE-patients under topical steroid treatment. METHODS In this prospective observational study, symptomatic EoE patients received HRM-examinations before and after 8 weeks of topical steroid treatment with budesonide. All HRM-abnormalities were assessed and interpreted according to the Chicago classification. The primary endpoint was the influence of topical steroid treatment on the intrabolus pressure (IBP). Clinical symptoms, endoscopic findings and histological esophageal eosinophilic load were also reported. KEY RESULTS Twenty symptomatic EoE patients were included. Overall success of budesonide therapy was 85% regarding complete histologic remission and 80% regarding complete clinical remission. High-resolution manometry showed abnormal esophageal motility in 35% of patients at baseline, which was resolved after therapy in 86% of these patients. Most frequent HRM-findings were early pan-esophageal pressurizations and weak persitalsis. There was no significant reduction of the IBP under therapy (before: 12.5 ± 4.9 mmHg, after: 10.9 ± 2.9 mmHg; p = 0.119). CONCLUSIONS & INFERENCES Although dysphagia is the leading symptom of EoE, HRM is able to identify esophageal motility disorders in only some EoE patients. Observed motility disorders resolve after successful treatment in almost all of these patients. Intrabolus pressure does not seem an optimal parameter for the monitoring of successful treatment response in EoE patients.

Abstract
BACKGROUND Controversy surrounds the clinical and histological response to topical steroids in patients with eosinophilic oesophagitis (EoE). AIM To perform a systematic review and network meta-analysis of randomised controlled trials to assess the efficacy of topical steroids compared with placebo or proton pump inhibitor (PPIs) for the management of eosinophilic oesophagitis. METHODS Cochrane Central Register of Controlled Trials and MEDLINE from inception to 1 July 2015 was searched. Data were extracted independently by two authors. Methodological quality was assessed using the Cochrane risk of bias tool. A network meta-analysis was performed using the Bayesian methods under random-effects multiple treatment comparisons. Results were summarised as odds ratio along with credibility intervals. We also calculated the ranking probability for each treatment based on surface under the cumulative ranking curve (SUCRA). RESULTS The overall methodological quality of included studies was low. SUCRA ranking probability indicated that PPI had the highest probability of being the best treatment for achieving histological remission and mean change in eosinophils (0.81 and 0.85, respectively), followed by budesonide (0.74 and 0.63, respectively) and fluticasone (0.5 and 0.5, respectively). None of the comparisons indicated a statistically signicant difference. CONCLUSIONS The results from network meta-analysis show that there is no statistically significant difference between PPI, budesonide and fluticasone for the treatment of EoE as assessed by the histological and clinical response. The evidence is limited by serious risk of bias and imprecision, which emphasises the urgent need for large RCTs with adequate sample size and methodological rigour to provide conclusive evidence.

Abstract
Eosinophilic esophagitis (EoE) is an allergy-mediated disease culminating in severe eosinophilic inflammation and dysfunction of the esophagus. This chronic disorder of the esophagus causes significant morbidity, poor quality of life, and complications involving fibrosis and esophageal remodeling. Overlapping features between EoE and gastroesophageal reflux disease (GERD) pose great challenges to differentiating the two conditions, although the two disorders are not mutually exclusive. Recent findings suggest that the confounding condition proton pump inhibitor - responsive esophageal eosinophilia (PPI-REE) is likely a subset of EoE. Since PPIs have therapeutic properties that can benefit EoE, PPIs should be considered as a therapeutic option for EoE rather than a diagnostic screen to differentiate GERD, PPI-REE, and EoE. Other current treatments include dietary therapy, corticosteroids, and dilation. Immunomodulators and biologic agents might have therapeutic value, and larger trials are needed to assess efficacy and safety. Understanding the pathophysiology of EoE is critical to the development of novel therapeutics.

Peripheral blood eosinophils and other non-invasive biomarkers can monitor treatment response in eosinophilic oesophagitis. Aliment Pharmacol Ther 2015; 42:1122-30. [PMID: 26314389 DOI: 10.1111/apt.13386] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2015] [Revised: 06/17/2015] [Accepted: 08/09/2015] [Indexed: 12/12/2022]
Abstract
BACKGROUND Monitoring of the treatment response in eosinophilic oesophagitis (EoE) requires structured endoscopical and histological examination of the oesophagus. Less invasive methods would be highly desirable. AIM To evaluate the utility of several EoE-associated blood and serum markers in order to non-invasively monitor the response to treatment with swallowed topical corticosteroids in adult EoE patients. METHODS In a randomised, controlled double-blind trial blood samples of EoE patients (n = 69) were collected at baseline and after 14 days of treatment with budesonide (n = 51) or placebo (n = 18) respectively. Absolute blood eosinophil count (AEC) as well as serum levels of CCL-17, CCL-18, CCL-26, eosinophil-cationic-protein (ECP) and mast cell tryptase (MCT) were determined and correlated with oesophageal eosinophil density and with symptom and endoscopy scores. RESULTS Histological remission, defined as mean number of <16 eos/mm(2) hpf at end-of-treatment, was achieved in 98% of the budesonide and 0% of the placebo recipients. AEC [380.2 vs. 214.7/mm(3) (P = 0.0001)], serum-CCL-17 [294.3 vs. 257.9 pg/mL (P = 0.0019)], -CCL-26 [26.7 vs. 16.2 pg/mL (P = 0.0058)], -ECP [45.5 ± 44.7 vs. 27.5 ± 25.0 μg/L (P = 0.0016)] and -MCT [5.3 ± 2.9 vs. 4.5 ± 2.6 μg/L (P = 0.0019)] significantly decreased under budesonide but not under placebo. AEC significantly correlated with oesophageal eosinophil density before (r = 0.28, P = 0.0236) and after (r = 0.42, P = 0.0004) budesonide treatment. In ROC-AUC analyses post-treatment values of AEC were significantly associated with histological remission (ROC-AUC 0.754; 95% CI: 0.617-0.891; P = 0.0003). CONCLUSIONS The budesonide-induced treatment response in EoE is mirrored by several blood and serum markers, and the absolute blood eosinophil count is the most valuable as it shows correlation with the oesophageal eosinophil density.

Abstract
Acute oesophageal symptoms include acute dysphagia or food bolus impaction (most commonly due to strictures, Schatzki ring and eosinophilic oesophagitis), acute chest pain with odynophagia due to oesophageal infections, motility disorders and acute oesophageal rupture (of which oesophageal intramural haematoma is a subtype). Acute full thickness oesophageal rupture carries a high mortality if not recognised early; the clinical features and conditions with which this may be confused are presented and discussed.
