Abstract
Objectives Dysphagia is a frequent symptom of active eosinophilic esophagitis (EoE), but at times it persists despite attaining histologic healing and lack of fibro-stenotic changes. We aimed to describe the manometric findings in this subset of patients. Methods A retrospective review of charts between 2013 and 2023 at a tertiary pediatric gastroenterology center, treating roughly 1500 EoE patients per year. We included children with EoE referred to high-resolution impedance manometry (HRIM) for persistent dysphagia despite histologic healing (i.e., <15 eosinophils/high-power field [Eos/hpf]). Data including initial EoE diagnosis, endoscopy reports, esophageal biopsies, treatment regimens, and HRIM were retrospectively collected. Results The estimated prevalence of post-remission dysphagia in our cohort was exceedingly rare (<0.05%). Four patients met the eligibility criteria of histologic remission and absence of fibro-stenotic features on endoscopic evaluation and thus, were included in this case series. Patients achieved remission with steroids, proton-pump inhibitor, or both within a median time of 5 months from diagnosis. Peak Eosinophil count at remission was ≤5 Eos/hpf in three patients and ≤10 Eos/hpf in one. On HRIM, all four patients had a hypomotile esophagus and abnormal bolus clearance. Lower esophageal sphincter integrated relaxation pressure values were normal in three patients and elevated in one. Two patients were diagnosed with ineffective esophageal motility, one with aperistalsis and one with achalasia type 1. Conclusions Post-remission dysphagia is rare in EoE. Esophageal dysmotility with a hypomotile pattern may contribute to the persistent dysphagia in children with EoE. HRIM should be considered in patients with EoE in whom symptoms persist despite histologic remission.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, progressive, type 2 inflammatory disease with increasing global prevalence. An eosinophil-predominant inflammation that permeates the epithelium and deeper esophageal layers characterizes the disease. Several cytokines, mainly derived from inflammatory T-helper 2 (Th2) cells and epithelial cells, are involved in perpetuating inflammatory responses by increasing surface permeability and promoting tissue remodeling characterized by epithelial-mesenchymal transition (EMT) and collagen deposition. This leads to esophageal strictures and narrow caliber esophagi, which are proportional a patient's age and untreated disease length. Pathophysiological mechanisms leading to EoE have been described in recent years, and transforming growth factor beta (TGF)-beta have been involved in fibrotic phenomena in EoE. However, evidence on the dependence of these phenomena on TGF-beta is scarce and contradictory. This review provides state-of-the art knowledge on intimate mechanisms of esophageal fibrosis in EoE and its clinical consequences.

Abstract
BACKGROUND There is conflicting evidence about the association between eosinophilic esophagitis (EoE) and esophageal motility disorders. The aim of this study was to evaluate esophageal manometry findings in EoE. METHODS We conducted a systematic review using PubMed, EMBASE, and Web of Science. All articles from 1990 to 2021 with EoE patients who underwent esophageal manometry were eligible. We also included pertinent abstracts from national conferences from 2015 to 2020. The primary outcomes were the prevalence of specific Chicago 3 Classification (CCv3) diagnoses in EoE, as well as broader categories of non-relaxing lower esophageal sphincter, and major and minor peristaltic disorders. When multiple studies reported a specific outcome, we performed random effects meta-analysis to obtain pooled prevalence of each outcome. To reduce heterogeneity, we restricted meta-analysis to high-resolution manometry (HRM) studies only. KEY RESULTS Of 763 publications identified, 27 original studies met criteria for inclusion, encompassing 706 EoE patients; 14 studies (425 patients) had HRM and underwent meta-analysis. The pooled prevalence of any motility abnormality was 53% (95% CI: 43%-63%), largely comprised of minor motility disorders such as ineffective esophageal motility and fragmented peristalsis. Major motility disorders, classified by CCv3, were less common in EoE, with pooled prevalence of 2% (0%-7%), 10% (5%-16%), and 1% (0%-3%), for achalasia, esophagogastric-junction outflow obstruction, and hypercontractile disorders, respectively. CONCLUSION AND INFERENCES Non-specific motility disorders were common in patients with EoE, but major motility disorders were rare. Further studies are needed to determine the relationship between eosinophilic infiltration and the clinical relevance of abnormal esophageal motility findings in this population.

Abstract
Eosinophilic esophagitis (EoE) represents a growing cause of chronic esophageal morbidity whose incidence and prevalence are increasing rapidly. The disease is characterized by eosinophilic infiltrates of the esophagus and organ dysfunction. Typical symptoms include dysphagia, chest pain, and bolus impaction, which are associated to mechanical obstructions in most patients. However, up to one in three EoE patients has no visible obstruction, suggesting that a motor disorder of the esophagus may underlie symptoms. Although potentially relevant for treatment refractoriness and symptomatic burden, esophageal dysmotility is often neglected when assessing EoE patients. The first systematic review investigating esophageal motility patterns in patients with EoE was published only recently. Accordingly, we reviewed the pathogenesis, assessment tools, manometric characteristics, and clinical implications of dysmotility in patients with EoE to highlight its clinical relevance. In summary, eosinophils can influence the amplitude of esophageal contractions via different mechanisms. The prevalence of dysmotility may increase with disease duration, possibly representing a late feature of EoE. Patients with EoE may display a wide range of motility disorders and possible disease-specific manometric pressurization patterns may be useful for raising a clinical suspicion. Intermittent dysmotility events have been found to correlate with symptoms on prolonged esophageal manometry, although high-resolution manometry studies have reported inconsistent results, possibly due to the suboptimal sensitivity of current manometry protocols. Motor abnormalities may recover following EoE treatment in a subset of patients, but invasive management of the motor disorder is required in some instances. In conclusion, esophageal motor abnormalities may have a role in eliciting symptoms, raising clinical suspicion, and influencing treatment outcome in EoE. The assessment of esophageal motility appears valuable in the EoE setting.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic disorder of the esophagus characterized by an eosinophil-predominant inflammation and symptoms of esophageal dysfunction. Eosinophils can influence esophageal motility, leading to dysphagia worsening. The spectrum of esophageal motility in EoE is uncertain. AIM We performed a systematic review to investigate esophageal motility in EoE. METHODS MEDLINE, EMBASE and EMBASE Classic were searched from inception to 16th November 2021. Studies reporting esophageal motility findings in EoE patients by means of conventional, prolonged, and/or high-resolution esophageal manometry were eligible. RESULTS Studies on esophageal conventional and high-resolution manometry (HRM) found that all types of manometric motor patterns can be found in patients with EoE and investigations on 24-hour prolonged manometry demonstrated an association between symptoms and intermittent dysmotility events, which can be missed during standard manometric analysis. Panesophageal pressurizations are the most common HRM finding and may help in formulating a clinical suspicion. Some motility abnormalities may reverse after medical treatment, while other major motility disorders like achalasia require invasive management for symptoms control. HRM metrics have demonstrated to correlate with inflammatory and fibrostenotic endoscopic features of EoE. CONCLUSION Esophageal motor abnormalities are common in patients with EoE and may contribute to symptoms. The resolution of dysmotility after medical treatment corroborates that eosinophils influence esophageal motility.

Abstract
Autoimmune diseases (AIDs) are often co-associated, and about 25% of patients with one AID tend to develop other comorbid AIDs. Here, we employ the power of datamining to predict the comorbidity of AIDs based on their normalized co-citation in PubMed. First, we validate our technique in a test dataset using earlier-reported comorbidities of seven knowns AIDs. Notably, the prediction correlates well with comorbidity (R = 0.91) and validates our methodology. Then, we predict the association of 100 AIDs and classify them using principal component analysis. Our results are helpful in classifying AIDs into one of the following systems: (1) gastrointestinal, (2) neuronal, (3) eye, (4) cutaneous, (5) musculoskeletal, (6) kidneys and lungs, (7) cardiovascular, (8) hematopoietic, (9) endocrine, and (10) multiple. Our classification agrees with experimentally based taxonomy and ranks AID according to affected systems and gender. Some AIDs are unclassified and do not associate well with other AIDs. Interestingly, Alzheimer’s disease correlates well with other AIDs such as multiple sclerosis. Finally, our results generate a network classification of autoimmune diseases based on PubMed text mining and help map this medical universe. Our results are expected to assist healthcare workers in diagnosing comorbidity in patients with an autoimmune disease, and to help researchers in identifying common genetic, environmental, and autoimmune mechanisms.

Abstract
Eosinophilic esophagitis (EoE) is an immune mediated chronic inflammatory disease resulting from antigen exposure and is characterized by mucosal inflammation with eosinophils. Diagnosis is based on the histological finding of at least 15 eosinophils per high power field in esophageal biopsy specimens from upper gastrointestinal endoscopies. These endoscopies are usually performed in the setting of esophageal dysfunction, however, EoE can occasionally be incidentally diagnosed during endoscopies performed for other indications like coeliac disease. The eosinophilia is in the absence of other causes of esophageal eosinophilia (e.g., parasitic infection, esophageal leiomyomatosis or Crohn's disease). Presentation can be wide ranging and often varies according to age. Infants and younger children can present with choking/gagging, feed refusal, failure to thrive, irritability and vomiting. Older children and adults commonly present with dysphagia, chest pain or food bolus obstruction. EoE was first described in the 1970s, but was only recognized as a distinct disease entity in the 1990s. It has been rising in incidence and prevalence, with reported prevalence ranging between 1 in 2,500 and 1 in 10,000. Although the diagnosis of EoE is dependent on clear histopathologic diagnostic criteria, there is a disconnect between the degree of esophageal eosinophilia and symptom severity especially that of reported dysphagia. Multiple anatomical changes can be seen in the spectrum of presentations of EoE which explain dysphagia, including isolated strictures, diffuse trachealisation, fixed rings, including Schatzki, as well as tissue remodeling and fibrotic changes. However, a majority of EoE patients do not have any of these findings and will still often report ongoing dysphagia. Some will report ongoing dysphagia despite histological remission. This suggests an underlying esophageal dysmotilty which cannot be assessed with endoscopy or correlated with histological changes seen in biopsies. This review will describe the types of motor disturbances seen and their prevalence, the pathophysiological basis of dysmotility seen in EoE, how best to investigate esophageal dysfunction in EoE and the role of manometry in the management of EoE.

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

Abstract
Eosinophilic esophagitis is a chronic condition that can affect any age, with an increasing prevalence in the last years. Esophageal symptoms are accompanied by normal endoscopic findings or changes suggestive for the disease, like rings, furrows, exudates, or strictures. The definitive diagnosis is based on esophageal biopsies, with identification of at least 15 eosinophils/high power field. In about 1/3 of patients esophageal motility abnormalities are observed. Ineffective esophageal motility is the most frequent. In some cases, major motility disorders, such as achalasia can be observed. The treatment depends on the patients' preferences and on symptoms severity, and usually a step-up approach is used. A diet change can be helpful in more than half of patients, some respond to proton pump inhibitors. In non-responders, short courses of topical corticosteroids are recommended. Endoscopic procedures might be helpful in patients with obstructive motility changes, non-responding to medical therapy.

Abstract
Abnormal oesophageal motility may impair oesophageal bolus transport leading to symptoms of chest pain and regurgitation. Oesophageal pathophysiology may include neuromuscular and/or structural defects leading to weak, incoordinate or absent peristalsis and impaired oesophago-gastric junction relaxation. Understanding these mechanisms is important to determine the appropriate course of therapy. Whilst, barium oesophagram is the mainstay for clinical investigation of oesophageal motility, high-resolution manometry is now more widely available. This review describes the potential value of high-resolution manometry in paediatric gastroenterology practise.

Abstract
Gastro-oesophageal reflux disease, eosinophilic oesophagitis and oesophageal motility disorders are among the most common diseases accompanying oesophageal eosinophilia. They have similarities and their limits are frequently not well defined. This article reviews the main characteristics relating to their similarities and differences, highlighting existing controversies among these diseases, in addition to current knowledge. In the case of a patient with symptoms of oesophageal dysfunction, it is suggested to carry out an integral analysis of the clinical features and diagnostic test results, including histology, while individualising each case before confirming a definitive diagnosis. Future investigation in paediatric patients is necessary to assess eosinophilic infiltration in the various layers of the oesophageal tissue, along with its clinical and pathophysiological implications.

Abstract
PURPOSE OF REVIEW Esophageal peristalsis is a highly sophisticated function that involves the coordinated contraction and relaxation of striated and smooth muscles in a cephalocaudal fashion, under the control of central and peripheral neuronal mechanisms and a number of neurotransmitters. Esophageal peristalsis is determined by the balance of the intrinsic excitatory cholinergic, inhibitory nitrergic and post-inhibitory rebound excitatory output to the esophageal musculature. RECENT FINDINGS Dissociation of the longitudinal and circular muscle contractions characterizes different major esophageal disorders and leads to esophageal symptoms. Provocative testing during esophageal high-resolution manometry is commonly employed to assess esophageal body peristaltic reserve and underpin clinical diagnosis. Herein, we summarize the main factors that determine esophageal peristalsis and examine their role in major and minor esophageal motility disorders and eosinophilic esophagitis.

Abstract
With the advances in technology and medical knowledge, new diseases are being identified and investigated. Esophageal motility disorders have been re-defined using high-resolution manometry and their pathogenesis are being better understood. The use of opioid analgesics is increasing worldwide, particularly in the United States, but their chronic use can cause opioid-induced esophageal dysfunction, which mimics spastic motor disorders, including achalasia type 3 or 2 and esophagogastric junction outflow obstruction. Eosinophilic esophagitis is identified by eosinophilic infiltration confirmed on a pathological examination. The condition is often associated with esophageal motility abnormalities. On the other hand, recent studies have suggested that muscle-predominant eosinophilic infiltration, eosinophilic esophageal myositis, might manifest as spastic motor disorders, including achalasia or jackhammer esophagus. Lymphocytic esophagitis is an unusual esophageal condition, which is confirmed by the increased number of lymphocytes in the esophageal epithelium. Although several reports have supported the existence of lymphocytic esophagitis, it is still unclear whether lymphocytic esophagitis is a distinct disease entity or another spectrum of other esophageal diseases, such as gastroesophageal reflux disease or eosinophilic esophagitis. This review presents evidence and reports on the emerging issues in esophageal motility disorders, including opioid-induced esophageal dysfunction, eosinophilic esophagitis with eosinophilic esophageal myositis, and lymphocytic esophagitis.

Abstract
There is an increasing prevalence of esophageal diseases but intact human tissue platforms to study esophageal function, disease mechanisms, and the interactions between cell types in situ are lacking. To address this, we utilized full thickness human donor esophagi to create and validate the ex vivo function of mucosa and smooth muscle (n = 25). Explanted tissue was tested for contractile responses to carbachol and histamine. We then treated ex vivo human esophageal mucosa with a cytokine cocktail to closely mimic the Th2 and inflammatory milieu of eosinophilic esophagitis (EoE) and assessed alterations in smooth muscle and extracellular matrix function and stiffening. We found that full thickness human esophagus as well as the individual layers of circular and longitudinal muscularis propria developed tension in response to carbachol ex vivo and that mucosa demonstrated squamous cell differentiation. Treatment of mucosa with Th2 and fibrotic cytokines recapitulated the majority of the clinical Eosinophilic Esophagitis Diagnostic Profile (EDP) on fluidic transcriptional microarray. Transforming growth factor-beta-1 (TGFβ1) increased gene expression of fibronectin, smooth muscle actin, and phospholamban (p < 0.001). The EoE cocktail also increased stiffness and decreased mucosal compliance, akin to the functional alterations in EoE (p = 0.001). This work establishes a new, transcriptionally intact and physiologically functional human platform to model esophageal tissue responses in EoE.

Clinical Characteristics and Associated Systemic Diseases in Patients With Esophageal "Absent Contractility"-A Clinical Algorithm. J Clin Gastroenterol 2019; 53:184-190.

Abstract
GOALS This study was carried out to assess the clinical characteristics and associated systemic diseases seen in patients diagnosed with absent contractility as per the Chicago Classification version 3.0, allowing us to propose a diagnostic algorithm for their etiologic testing. BACKGROUND The Chicago Classification version 3.0 has redefined major and minor esophageal motility disorders using high-resolution esophageal manometry. There is a dearth of publications based on research on absent contractility, which historically has been associated with myopathic processes such as systemic sclerosis (SSc). STUDY We conducted a retrospective, multicenter study. Data of patients diagnosed with absent contractility were pooled from Cleveland Clinic, Cleveland, OH (January 2006 to July 2016) and Metrohealth Medical Center, Cleveland, OH (July 2014 to July 2016) and included: age, gender, associated medical conditions, surgical history, medications, and specific antibody testing. RESULTS A total of 207 patients, including 57 male individuals and 150 female individuals, with mean age of 56.1 and 60.0 years, respectively, were included. Disease distribution was as follows: SSc (diffuse or limited cutaneous) 132, overlap syndromes 7, systemic lupus erythematosus17, Sjögren syndrome 4, polymyositis 3, and dermatomyositis 3. Various other etiologies including gastroesophageal reflux disease, postradiation esophagitis, neuromuscular disorders, and surgical complications were seen in the remaining cohort. CONCLUSIONS Most practitioners use the term "absent contractility" interchangeably with "scleroderma esophagus"; however, only 63% of patients with absent contractility had SSc. Overall, 20% had another systemic autoimmune rheumatologic disease and 16% had a nonrheumatologic etiology for absent contractility. Therefore, alternate diagnosis must be sought in these patients. We propose an algorithm for their etiologic evaluation.

Abstract
This report explores two hypotheses regarding eosinophilic esophagitis (EoE): (1) that the use of proton pump inhibitors (PPIs) might contribute to the pathogenesis of EoE by preventing peptic digestion of food allergens, by increasing gastric mucosal permeability to enable gastric absorption of those undegraded food allergens, and by causing microbial dysbiosis, and (2) that EoE, like eosinophilic gastroenteritis, might have mucosal-predominant and muscle-predominant forms, and that the muscle-predominant form of EoE might cause a variety of esophageal motility disorders including achalasia.

Abstract
Eosinophilic esophagitis (EoE), a Th2-type allergic immune disorder characterized by an eosinophil-rich esophageal immune infiltrate, is often associated with food impaction (FI) in pediatric patients but the molecular mechanisms underlying the development of this complication are not well understood. We aim to identify molecular pathways involved in the development of FI. Due to large variations in disease presentation, our analysis was further geared to find markers capable of distinguishing EoE patients that are prone to develop food impactions and thus expand an established medical algorithm for EoE by developing a secondary analysis that allows for the identification of patients with food impactions as a distinct patient population. To this end, mRNA patterns from esophageal biopsies of pediatric EoE patients presenting with and without food impactions were compared and machine learning techniques were employed to establish a diagnostic probability score to identify patients with food impactions (EoE+FI). Our analysis showed that EoE patients with food impaction were indistinguishable from other EoE patients based on their tissue eosinophil count, serum IgE levels, or the mRNA transcriptome-based p(EoE). Irrespectively, an additional analysis loop of the medical algorithm was able to separate EoE+FI patients and a composite FI-score was established that identified such patients with a sensitivity of 93% and a specificity of 100%. The esophageal mRNA pattern of EoE+FI patients was typified by lower expression levels of mast cell markers and Th2 associated transcripts, such as FCERIB, CPA3, CCL2, IL4, and IL5. Furthermore, lower expression levels of regulators of esophageal motility (NOS2 and HIF1A) were detected in EoE+FI. The EoE+FI -specific mRNA pattern indicates that impaired motility may be one underlying factor for the development of food impactions in pediatric patients. The availability of improved diagnostic tools such as a medical algorithm for EoE subpopulations will have a direct impact on clinical practice because such strategies can identify molecular inflammatory characteristics of individual EoE patients, which, in turn, will facilitate the development of individualized therapeutic approaches that target the relevant pathways affected in each patient.

Abstract
Eosinophilic esophagitis (EoE), a disorder identified by its esophageal mucosal features, often is associated with esophageal motility abnormalities, which are manifestations of esophageal muscle dysfunction. Those motility abnormalities sometimes normalize with treatments that reduce esophageal eosinophilia, suggesting that eosinophils can cause reversible esophageal motility disturbances, perhaps by releasing myoactive and neuroactive eosinophil products. Although achalasia uncommonly is associated with EoE as currently defined, most achalasia patients have evidence of an abnormal accumulation of eosinophils and/or their degranulation products in the esophageal muscularis propria, a location inaccessible to routine endoscopic evaluation. Achalasia is an idiopathic condition resulting from destruction of neurons in the myenteric plexus of the esophagus, and degranulating eosinophils release toxic proteins capable of destroying those neurons, thereby causing the irreversible motility abnormalities of achalasia. This report reviews data on the association of esophageal eosinophilia with achalasia and other esophageal motility abnormalities. Based on this review, we propose that EoE, like eosinophilic gastroenteritis, might have mucosal-predominant and muscle-predominant forms with different clinical manifestations. A muscle-predominant form of EoE could underlie a variety of reversible and irreversible esophageal motility disorders, including achalasia. The concept that esophageal motility abnormalities might develop from a muscle-predominant form of EoE warrants serious consideration and further investigation.

Abstract
Classically, eosinophilic esophagitis is an antigen-mediated chronic disease distinct from gastroesophageal reflux disease. Eosinophilic esophagitis is an emerging clinical problem that is growing in recognition. It is characterized clinically by feeding dysfunction, dysphagia, and reflux-like symptoms. Histologically, eosinophilic esophagitis is identifiable by a dense epithelial eosinophilic infiltrate. Experimental modeling and clinical studies over the last decade have greatly improved mechanistic insights and led to improvements in clinical understanding and the assessment of therapeutic options for patients and their clinicians who manage this disease. Here, we review the clinicopathologic diagnostic criteria and our understanding of eosinophilic esophagitis as an allergic disease with genetic and immunological components. We present studies defining the importance of the epithelial barrier and the concept of barrier dysfunction as an initiating or perpetuating factor for this disease. We discuss the relationship between the symptoms of dysphagia and feeding dysfunction, our current knowledge of the underlying pathophysiologic mechanisms, and advances in clinical assessment of esophageal distensibility and narrowing in eosinophilic esophagitis patients. Finally, therapeutic implications relating to the advances that have led to our current understanding of the pathophysiology of eosinophilic esophagitis are explored.

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
This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance.

Abstract
Eosinophilic esophagitis is a chronic immunoallergic inflammatory disease of the esophagus that represents a major cause of digestive morbidity among the pediatric and young adult populations. Despite the fact that key symptoms in adults include dysphagia and food impaction, many patients lack structural changes in the esophagus to account for their complaints, which suggests the presence of underlying motor disorders and esophageal distensibility impairment. In the last few years the esophageal motility of these patients has been studied using various approaches, most particularly high-resolution manometry, ambulatory manometry, and impedance planimetry. This review focuses on the most relevant findings and scientific evidence regarding esophageal motor disorders in eosinophilic esophagitis.

Abstract
Esophageal dysmotility is almost universal after esophageal atresia (EA) repair and is mainly related to the developmental anomaly of the esophagus. Esophageal dysmotility is involved in the pathophysiology of numerous symptoms and comorbidities associated with EA such as gastroesophageal reflux disease, aspiration and respiratory complications, and symptoms of dysphagia and feeding disorders. High-resolution esophageal manometry (HREM) has facilitated the characterization of the dysmotility, but there is an incomplete correlation between symptoms and manometrical patterns. Impedance coupled to HREM should help to predict the clinical outcome and therefore personalize patient management. Nowadays, the management of esophageal dysmotility in patients with EA is essentially based on treatment of associated inflammation related to peptic or eosinophilic esophagitis.

Abstract
The Chicago classification (CC) is most valued for its systematic approach to esophageal disorders and great impact in unifying practice for esophageal manometric studies. In view of the ever-growing wealth of knowledge and experience gained by the expanding use of high-resolution manometry (HRM) in various clinical scenarios, the CC is regularly updated. Its clinical impact and ability to predict clinical outcome, both in adults and pediatrics, will be further promoted by recognizing its current limitations, incorporating new metrics in its diagnostic algorithms and adjusting the HRM protocols based on the clinical question posed. Herein, we discuss the current limitations of the CC and highlight some areas of improvement for the future.

Abstract
Purpose The clinical, endoscopic, and histologic findings of eosinophilic esophagitis (EoE) are well characterized; however, there have been very limited data regarding the radiologic findings of pediatric EoE. We report on the radiologic findings of pediatric EoE observed on barium esophagram and correlate them with the endoscopic findings. Methods and materials We identified children diagnosed with EoE in our center from 2004 to 2015. Two pediatric radiologists met after their independent evaluations of each fluoroscopic study to reach a consensus on each case. Clinical and endoscopic data were collected by retrospective chart review. Results Twenty-six pediatric EoE cases (age range 2–13 years; median 7.5 years) had barium esophagram done as part of the diagnostic approach for dysphagia. Thirteen children had abnormal radiologic findings of esophagus (50%): rings formation (n = 4), diffuse irregularity of mucosa (n = 8), fixed stricture formation (n = 3), and narrow-caliber esophagus (n = 10). Barium esophagram failed to show one of 10 cases of narrow-caliber esophagus and 10 of 14 cases of rings formation visualized endoscopically. The mean duration of symptoms prior to diagnosis of EoE was longer (3.7 vs. 1.7 year; p value 0.019), and the presentation with intermittent food impaction was commoner in the group with abnormal barium esophagram as compared to the group with normal barium esophagram (69% vs. 8%; p value 0.04). Conclusion Barium swallow study is frequently normal in pediatric EoE. With the exception of narrow-caliber esophagus, our data show poor correlation between radiologic and endoscopic findings.

Abstract
Eosinophilic esophagitis is a worldwide chronic allergic disease of the esophagus. In the last decade, there is an epidemic of this entity in the western world. Mostly seen in children and young adults, patients present with dysphagia or food impaction in the emergency room. Characteristic endoscopic findings, esophageal eosinophilia and non-responsiveness to proton pump inhibitors help make the diagnosis. Avoidance of food allergens, administration of steroidal anti-inflammatory medications and dilation of the esophagus are the mainstays of treatment. Investigations are ongoing for mucosal healing and optimum maintenance treatment.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is characterized by eosinophilic infiltration of the esophagus and is a potential cause of dysphagia and food impaction, most commonly affecting young men. Esophageal manometry findings vary from normal motility to aperistalsis, simultaneous contractions, diffuse esophageal spasm, nutcracker esophagus or hypotonic lower esophageal sphincter (LES). It remains unclear whether esophageal dysmotility plays a significant role in the clinical symptoms of EoE. AIM Our aim is to review the pathogenesis, diagnosis, and effect of treatment on esophageal dysmotility in EoE. METHODS A literature search utilizing the PubMed database was performed using keywords: eosinophilic esophagitis, esophageal dysmotility, motility, manometry, impedance planimetry, barium esophagogram, endoscopic ultrasound, and dysphagia. RESULTS Fifteen studies, totaling 387 patients with eosinophilic esophagitis were identified as keeping in accordance with the aim of this study and included in this review. The occurrence of abnormal esophageal manometry was reported to be between 4 and 87% among patients with EoE. Esophageal motility studies have shown reduced distensibility, abnormal peristalsis, and hypotonicity of the LES in patients with EoE, which may also mimic other esophageal motility disorders such as achalasia or nutcracker esophagus. Studies have shown conflicting results regarding the presence of esophageal dysmotility and symptoms with some reports suggesting a higher rate of food impaction, while others report no correlation between motor function and dysphagia. CONCLUSIONS Motility dysfunction of the esophagus in EoE has not been well reported in the literature and studies have reported conflicting evidence regarding the clinical significance of dysmotility seen in EoE. The correlation between esophageal dysmotility and symptoms of EoE remains unclear. Larger studies are needed to investigate the incidence of esophageal dysmotility, clinical implications, and effect of treatment on patients with EoE.

Abstract
BACKGROUND During the natural course of eosinophilic esophagitis (EoE), the risk for esophageal stricture formation increases. It remains unknown whether motility abnormalities in EoE also develop over time. We aimed to determine the relationship between disease duration, clinical characteristics, and manometric pattern of EoE patients. METHODS We compared esophageal high-resolution manometry (HRM) measurements of 31 adult EoE patients with HRM data from 31 GERD controls and 31 healthy controls. Subsequently, we assessed differences in disease duration and clinical characteristics between EoE patients with normal and those with abnormal esophageal motility. KEY RESULTS In EoE patients, peristaltic integrity was more frequently failed (12 vs 6%) or weak (27 vs 15%; p < 0.001) compared with healthy controls; however, this pattern was also seen in GERD controls (failed 14%, weak 27%). We found no differences regarding symptoms and signs of EoE between EoE patients with normal (42%) and abnormal motility (58%). However, disease duration was longer in EoE patients with abnormal motility than in those with normal motility (13 (6-18) years vs 4 (1-11) years; p < 0.05). In EoE, but not GERD, disease duration was identified as a risk factor for abnormal motility (OR for each year 1.142; 95% CI 1.004-1.299), and with longer disease duration, the prevalence of abnormal motility increased from 36% (duration 0-5 years) to 83% (duration ≥16 years; p < 0.05). CONCLUSIONS & INFERENCES Weak and failed peristaltic integrity are more often present in adult EoE patients than in healthy controls. The prevalence of manometric abnormalities in EoE patients increases with longer disease duration.

Abstract
Eosinophilic esophagitis (EoE) is a clinicopathologic disease of increasing prevalence in children and adults. The triggering antigen in EoE is often a food that initiates a cascade of Th2-associated interleukins such as interleukin-5 and interleukin-13 and chemokines such as eotaxin-3 as well as esophageal eosinophilia and mastocytosis. Amino acid-based formulas have high efficacy rates in EoE and constitute the first evidence for food-triggered esophageal eosinophilia. Animal models have demonstrated the sufficiency of food antigens in triggering both the inflammatory and remodeling complications of EoE. Food elimination diets that are followed by single food introduction with repeat biopsy have proven the efficacy of empiric and allergy testing based elimination diets in children and adults. Although the ideal allergy test for identifying food antigens in EoE remains to be elucidated, the utility of food skin prick combined with atopy patch testing has been shown in large pediatric cohorts. By comparison, smaller, non-U.S. adult cohorts have not had similar results. Currently, a positive test on food allergy evaluation suggests a food trigger for EoE but does not substitute for biopsy-based tissue evaluation after food removal and reintroduction. The higher rates of food anaphylaxis in children with EoE, potential loss of tolerance to immunoglobulin E-positive foods that can occur with food avoidance, and the high rates of other atopic diatheses in EoE subjects all support the evaluation of EoE subject by an allergist, consideration for allergy testing, and an integrated approach by allergists, gastroenterologists, and pathologists in EoE management.

Abstract
In eosinophilic esophagitis (EoE), remodeling changes are manifest histologically in the epithelium and subepithelium where lamina propria fibrosis, expansion of the muscularis propria, and increased vascularity occur. The clinical symptoms and complications of EoE are largely consequences of esophageal remodeling. Available therapies have demonstrated variable ability to reverse existing remodeling changes of the esophagus. Systemic therapies have the potential of addressing subepithelial remodeling. Esophageal dilation remains a useful, adjunctive therapeutic maneuver in symptomatic adults with esophageal stricture. As novel treatments emerge, it is essential that therapeutic end points account for the fundamental contributions of esophageal remodeling to overall disease activity.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic antigen-mediated disease characterized by esophageal eosinophilia, remodeling, and fibrosis. TGF-β1 is a central regulator of EoE remodeling and increases esophageal smooth muscle (ESM) cell contraction. OBJECTIVE In this study we aimed to understand the molecular mechanisms by which TGF-β1 could induce ESM cell contraction. METHODS We used primary human ESM cells and esophageal myofibroblasts (EMFs) to assess the mechanisms of TGF-β1-induced contraction. We analyzed the expression, phosphorylation, and function of phospholamban (PLN), a sarcoendoplasmic reticulum regulatory protein induced by TGF-β1. Expression of PLN, phospho-PLN, and its regulatory pathway was analyzed in the ESM of biopsy specimens from patients with EoE and control subjects. Gene silencing in EMFs from patients with EoE was used to understand the role of PLN in contraction. RESULTS TGF-β1 induced and phosphorylated PLN in primary human ESM cells and EMFs from patients with EoE. PLN and phospho-PLN levels were increased in smooth muscle from patients with EoE compared with that seen in smooth muscle from control subjects in vivo. PLN inhibition significantly diminished TGF-β1-induced EMF contraction in patients with EoE. PLN expression and ESM/EMF contraction depended on TGF-β receptor I signals. CONCLUSION We describe a previously unrecognized mechanism for ESM cell contraction that depends on TGF-β1, its receptors, and PLN. Because PLN levels are increased in smooth muscle from patients with EoE and PLN silencing diminishes contraction, we provide a novel potential mechanistic framework and therapeutic target for ESM dysfunction in patients with EoE.

Abstract
BACKGROUND & AIMS Patients with eosinophilic esophagitis (EoE) often become dysphagic from the combination of organ fibrosis and motor abnormalities. We investigated mechanisms of dysphagia, assessing the response of human esophageal fibroblasts (HEFs), human esophageal muscle cells (HEMCs), and esophageal muscle strips to eosinophil-derived products. METHODS Biopsy specimens were collected via endoscopy from the upper, middle, and lower thirds of the esophagus of 18 patients with EoE and 21 individuals undergoing endoscopy for other reasons (controls). Primary cultures of esophageal fibroblasts and muscle cells were derived from 12 freshly resected human esophagectomy specimens. Eosinophil distribution was investigated by histologic analyses of full-thickness esophageal tissue. Active secretion of EoE-related mediators was assessed from medium underlying mucosal biopsy cultures. We quantified production of fibronectin and collagen I by HEF and HEMC in response to eosinophil products. We also measured the expression of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 by, and adhesion of human eosinophils to, HEFs and HEMCs. Eosinophil products were tested in an esophageal muscle contraction assay. RESULTS Activated eosinophils were present in all esophageal layers. Significantly higher concentrations of eosinophil-related mediators were secreted spontaneously in mucosal biopsy specimens from patients with EoE than controls. Exposure of HEFs and HEMCs to increasing concentrations of eosinophil products or co-culture with eosinophils caused HEFs and HEMCs to increase secretion of fibronectin and collagen I; this was inhibited by blocking transforming growth factor β1 and p38 mitogen-activated protein kinase signaling. Eosinophil binding to HEFs and HEMCs increased after incubation of mesenchymal cells with eosinophil-derived products, and decreased after blockade of transforming growth factor β1 and p38 mitogen-activated protein kinase blockade. Eosinophil products reduced electrical field-induced contraction of esophageal muscle strips, but not acetylcholine-induced contraction. CONCLUSIONS In an analysis of tissues samples from patients with EoE, we linked the presence and activation state of eosinophils in EoE with altered fibrogenesis and motility of esophageal fibroblasts and muscle cells. This process might contribute to the development of dysphagia.

Abstract
Chronic eosinophilic inflammation has been associated with tissue remodeling in a number of disease states including the hypereosinophilic syndrome (HES), asthma, and, more recently, eosinophilic esophagitis (EoE). Remodeling occurs in the epithelial and subepithelial esophageal tissue, and includes basal zone hyperplasia, epithelial mesenchymal transition, fibrosis, angiogenesis, and smooth muscle hypertrophy/hyperplasia. Previously, research on the clinical impacts of tissue remodeling has been limited by a paucity of human tissue. However, in EoE, recurrent biopsies are required for diagnosis and management. As such, investigators are able to study the associations between tissue changes and clinical disease features. A number of profibrotic and proangiogenic factors are elevated in EoE, including TGF-β1, CCL-18, FGF-9, VEGF, and VCAM-1. Both eosinophils and mast cells produce a number of these factors. TGF-β1 appears to be a master regulator of end-organ dysfunction in EoE and can cause esophageal epithelial mesenchymal transition, fibrosis, and smooth muscle contraction. The requirement for eosinophils, the eosinophilopoietic interleukin, IL-5, and the canonical TGF-β1 signaling pathway for EoE-associated fibrosis, has been invoked using gene-deficient mice. The clinical consequences of eosinophil-associated tissue fibrosis can be devastating, such as endomyocardial fibrosis and heart failure in HES. In EoE, tissue remodeling appears to be the mechanism for multiple cardinal disease complications including esophageal rigidity, strictures, narrowing, and food impactions, as well as the clinical hallmark of dysphagia. Therapies that may be able to reduce or reverse EoE-associated remodeling include topical corticosteroids, anti-IL-5, and food antigen avoidance.

Abstract
Eosinophilic oesophagitis is a chronic inflammatory disease characterized by eosinophilic infiltration of the oesophageal mucosa. Food and aero-allergens are involved in its pathogenesis. Dysphagia and food impaction are the dominant symptoms in adult with eosinophilic oesophagitis. However, a wide range of symptoms has been noticed such as chest pain or gastro-oesophageal reflux disease-like symptoms. Upper gastro-intestinal endoscopy and oesophageal biopsies are crucial for the diagnosis of eosinophilic oesophagitis. Endoscopy might be normal or reveal typical patterns such as rings, furrows, exudates, oedema, and stricture. Two to four biopsies should be performed both in the distal and in the proximal oesophagus, and 15 eosinophils per high power field within the oesophageal epithelium are the minimal threshold to diagnose eosinophilic oesophagitis. Allergy testing is recommended, although its impact to orient treatment remains to be demonstrated. Eosinophilic oesophagitis treatment includes medical treatment, diet and endoscopic dilation. Proton pump inhibitors are the first-line therapy as some eosinophilic oesophagitis phenotypes respond well to proton pump inhibitors. Topical viscous corticosteroids or diet elimination are the treatment of choice. There is no clear evidence in the literature to prefer one to the other. Finally endoscopic dilation should be considered in case of persistent symptomatic stenosis despite medical therapy.

Endoscopy with biopsy is currently the only method to assess oesophageal mucosal inflammation in EoE. We hypothesised that measurements of luminal eosinophil-derived proteins would correlate with oesophageal mucosal inflammation in children with EoE. DESIGN The Enterotest diagnostic device was used to develop an oesophageal string test (EST) as a minimally invasive clinical device. EST samples and oesophageal mucosal biopsies were obtained from children undergoing upper endoscopy for clinically defined indications. Eosinophil-derived proteins including eosinophil secondary granule proteins (major basic protein-1, eosinophil-derived neurotoxin, eosinophil cationic protein, eosinophil peroxidase) and Charcot-Leyden crystal protein/galectin-10 were measured by ELISA in luminal effluents eluted from ESTs and extracts of mucosal biopsies. RESULTS ESTs were performed in 41 children with active EoE (n=14), EoE in remission (n=8), gastro-oesophageal reflux disease (n=4) and controls with normal oesophagus (n=15). EST measurement of eosinophil-derived protein biomarkers significantly distinguished between children with active EoE, treated EoE in remission, gastro-oesophageal reflux disease and normal oesophagus. Levels of luminal eosinophil-derived proteins in EST samples significantly correlated with peak and mean oesophageal eosinophils/high power field (HPF), eosinophil peroxidase indices and levels of the same eosinophil-derived proteins in extracts of oesophageal biopsies. CONCLUSIONS The presence of eosinophil-derived proteins in luminal secretions is reflective of mucosal inflammation in children with EoE. The EST is a novel, minimally invasive device for measuring oesophageal eosinophilic inflammation in children with EoE.

Potential for improving therapy and defining new research targets in eosinophilic oesophagitis based on understanding of immunopathogenesis. J Pediatr Gastroenterol Nutr 2013; 57:529-34.

Abstract
OBJECTIVES This review considers the potential for therapeutic advances in the management of eosinophilic oesophagitis (EoE) based on recently increased understanding of the pathophysiology of the disorder. METHODS This is a review of publications characterising mucosal changes and leucocyte recruitment patterns in human and experimental EoE. RESULTS EoE, although diagnosed by epithelial infiltration of eosinophils, is actually a transmural inflammation in which eosinophil recruitment occurs via the deeper layers. Penetration of eosinophils into the epithelium is variable, explaining the need for multiple biopsies to diagnose what may be a clearly visible disorder. Fibrosis and neuromuscular dysfunction both occur within the subepithelial tissues. Recent murine studies have identified that T-cell recruitment underpins antigen-specific oesophageal eosinophil recruitment. Involvement of innate immunity is also suggested by the role of invariant natural killer T cells in experimental EoE. CONCLUSIONS Looking beyond present therapeutic options with a view to future studies, we identify T cells as candidates for "upstream therapy" if antigen specificity or homing markers are determined. Evidence of aeroallergen sensitisation suggests the possibility of lymphocyte priming within nasal-associated lymphoid tissue or Waldeyer ring, with the potential for topical therapy. We consider acquired neuromuscular dysfunction as a therapeutic target in acute symptomatic deterioration or bolus obstruction. We assess possible similarities with therapeutic stratagems for chronic asthma, recognising at the same time the anatomic specificity of the oesophagus and the difficulty in delivering effective topical medication to subepithelial tissues in this location compared with the airway.

Abstract
Diffuse esophageal spasm (DES) causes chest pain and/or dysphagia in adults. We reviewed charts of 278 subjects 0 to 18 years of age after esophageal manometry to describe the frequency and characteristics of DES in children. Patient diagnoses included normal motility (61%), nonspecific esophageal motility disorder (20%), DES (13%, n=36), and achalasia (4%). Of patients with DES, the most common chief complaint was food refusal in subjects younger than 5 years (14/24, 58%) and chest pain in subjects older than 5 years (4/12, 33%). Comorbid medical conditions, often multiple, existed in 33 subjects. DES should be considered when young children present with food refusal.

Abstract
Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition whereby infiltration of eosinophils into the esophageal mucosa leads to symptoms of esophageal dysfunction. EoE is encountered in a substantial proportion of patients undergoing diagnostic upper endoscopy. This review discusses the clinical, endoscopic, and histologic features of EoE and presents the most recent guidelines for its diagnosis. Selected diagnostic dilemmas are described, including distinguishing EoE from gastroesophageal reflux disease and addressing the newly recognized clinical entity of proton-pump inhibitor-responsive esophageal eosinophilia. Also highlighted is evidence to support both pharmacologic and nonpharmacologic treatments, including topical corticosteroids, dietary elimination therapy, and endoscopic dilation.

Abstract
Esophageal motor function is highly coordinated between central and enteric nervous systems and the esophageal musculature, which consists of proximal skeletal and distal smooth muscle in three functional regions, the upper and lower esophageal sphincters, and the esophageal body. While upper endoscopy is useful in evaluating for structural disorders of the esophagus, barium esophagography, radionuclide transit studies, and esophageal intraluminal impedance evaluate esophageal transit and partially assess motor function. However, esophageal manometry is the test of choice for the evaluation of esophageal motor function. In recent years, high-resolution manometry (HRM) has streamlined the process of acquisition and display of esophageal pressure data, while uncovering hitherto unrecognized esophageal physiologic mechanisms and pathophysiologic patterns. New algorithms have been devised for analysis and reporting of esophageal pressure topography from HRM. The clinical value of HRM extends to the pediatric population, and complements preoperative evaluation prior to foregut surgery. Provocative maneuvers during HRM may add to the assessment of esophageal motor function. The addition of impedance to HRM provides bolus transit data, but impact on clinical management remains unclear. Emerging techniques such as 3-D HRM and impedance planimetry show promise in the assessment of esophageal sphincter function and esophageal biomechanics.

Abstract
BACKGROUND Fibrosis of the esophageal lamina propria is a known complication of eosinophilic esophagitis (EoE). To date, therapy with topical corticosteroids has been shown to reverse esophageal fibrosis in some patients; however, there is little evidence to suggest that dietary therapy can also reverse it. Our aim was to examine whether dietary therapy alone can reverse esophageal fibrosis in children with EoE. METHODS We performed a historical cohort study based on children with EoE who had esophageal fibrosis on pretreatment biopsies using trichrome staining. Post-treatment biopsies were analyzed for fibrosis reversal, and results were compared between patients treated with dietary restriction and those that received topical steroids. Clinical characteristics (age, symptoms, duration of symptoms prior to therapy, treatment type, and duration of therapy) were recorded. Histological markers (eosinophil numbers and eosinophilic degranulation in both epithelium and lamina propria, basal zone hyperplasia, and the presence of eosinophilic microabscesses in the epithelium) were examined by reviewing hematoxylin and eosin-stained biopsies and by immunohistochemical staining. These were examined as potential predictors for fibrosis reversal. RESULTS Fibrosis resolved following both dietary restriction and topical steroids (3/17 and 5/9 patients respectively, P = 0.078). Post-treatment symptom resolution and decreased intraepithelial eosinophil numbers were found to be the only significant predictors of fibrosis resolution. CONCLUSIONS Dietary restriction alone, similar to topical steroids, can reverse fibrosis in children with EoE.

Abstract
Eosinophilic esophagitis (EoE) is now recognized as a common cause of dysphagia. Eosinophilic infiltration of the esophagus has also been associated with other conditions, such as gastroesophageal reflux disease (GERD); however, the incidence, pattern, and clinical significance of eosinophilic infiltration in achalasia are poorly documented. We sought to characterize this histological finding in patients undergoing Heller myotomy (HM) for achalasia. Ninety-six patients undergoing laparoscopic HM for primary achalasia between 1999 and 2008 were identified from a prospective database. Serial mid and distal per-endoscopic esophageal biopsies taken from patients before and after surgery were assessed for the presence of elevated intraepithelial eosinophils (EIEs). Slides from patients with reports suggestive of EIE were reviewed independently by two pathologists, and the highest eosinophil count/high-power field (eos/hpf) was recorded. Dysphagia scores (0 = none to 5 = severe dysphagia), GERD health-related quality of life scores (0 = best to 45 = worst), and 24-hour pH results were compared before and 3 months after surgery. We related the highest eos to the symptoms and response to HM. Data are presented as median (range). Paired t-test and Wilcoxon signed-rank test determined significance, *P < 0.05. Of 96 patients with achalasia, 50 had undergone pre-HM biopsies revealing EIE in 17/50 (34%), with a median of 3 eos/hpf (1-21). Two patients were found to have superimposed esophageal candidiasis. One patient met the pathologic criteria for EoE. Twenty-five of 50 (50%) postoperative biopsies demonstrated a median of 5 eos/hpf (1-62) for a total of 28/50 patients (56%) with EIE in either the preoperative or postoperative period. Four patients (8%) met the pathologic criteria for EoE, and two demonstrated persistent esophageal candidiasis. A decrease in eosinophils was found in 6/28 patients (21%) from 3/hpf (1-21) to 0.5/hpf (0-4). Increase in eosinophils was found in 22/28 patients (79%) from 0.5/hpf (0-8) to 5/hpf (1-62). Preoperative and postoperative dysphagia scores were available in 23 patients. Dysphagia scores improved in 22/23 patients. (3 [0-5] to 0 [0-2])*. Preoperative and postoperative GERD scores were available in 21 patients. GERD scores improved in 20/21 patients (10 [3-38] to 2 [2-14])*. Four of 13 patients (30.7%) demonstrated significant reflux in the postoperative period. No difference in clinical response to HM was detected between patients with preoperative EIE compared with patients with no EIE. No correlation between postoperative esophageal pH and eos was observed. A significant number of patients with achalasia demonstrate esophageal eosinophilic infiltration even at numbers demonstrable in patients with EoE (8% 4/50). While the interaction between achalasia and esophageal eosinophilic infiltration needs further investigation, this does not represent a distinct clinical entity. Thus, the presence of esophageal eosinophils in patients presenting with dysphagia should not preclude further work-up for other etiologies, including achalasia.

Abstract
Eosinophilic gastrointestinal diseases are a group of chronic diseases characterized by a range of symptoms caused by eosinophilic inflammation of various parts of the gastrointestinal tract. Other causes for eosinophilia need to be ruled out prior to making the diagnosis of EGIDs. The most common form of EGID is eosinophilic esophagitis (EoE), an antigen-driven disease that afflicts children and adults and has been identified across the world. Histological features include dense eosinophilia of the esophageal mucosa, eosinophil degranulation, eosinophil microabscess formation, and other features of epithelial inflammation including basal zone hyperplasia and rete pege elongation. Treatments include dietary exclusions and topical corticosteroids.

Abstract
BACKGROUND Eosinophilic esophagitis (EE) is an inflammatory disorder of the esophagus characterized by symptoms such as dysphagia, food sticking and heartburn. Several fluoroscopic findings have been described in EE, but the frequency of these findings is unknown. OBJECTIVE To identify the frequency of imaging findings in pediatric-age patients with eosinophilic esophagitis. MATERIALS AND METHODS A retrospective study was performed evaluating all upper GI and esophagram studies performed between 2000 and 2008 in patients up to age 21 with a pathological diagnosis of EE. In order to be included in the study, the upper GI or esophagram had to be performed either before EE was diagnosed or within 30 days of the diagnosis. Two pediatric radiologists evaluated each study for the presence or absence of multiple findings of EE. The radiology reports from the time of the study were then read to establish a concurrent diagnosis of esophageal dysmotility or gastroesophageal reflux. Finally, the hospital electronic medical record was evaluated to obtain demographic and pathology information. RESULTS Of the 579 patients with biopsy-proven EE, 107 (18%) were included in the study and underwent a total of 112 upper GI or esophagram examinations. The most common finding on these examinations was a normal esophagus (58/112; 52%) followed by gastroesophageal reflux (21/112; 19%) and irregular contractions (17/112; 15%). Less frequent findings included strictures, dysmotility, mucosal irregularity, esophageal rings and filling defects. CONCLUSION Fluoroscopic studies are not a sensitive method to diagnose EE because nearly half of the studies are normal. Findings that have been described in the setting of EE such as food impaction, a ringed esophagus, a small-caliber esophagus and esophageal stricture do not occur with a high enough frequency to reliably make a diagnosis.

Abstract
BACKGROUND AND AIMS Leukotriene D4 is produced by and functions as a chemotactic factor for eosinophils. Eosinophilic esophagitis (EoE) is characterized by esophageal eosinophilic infiltration, determining structural changes and dismotility symptoms. Montelukast, a selective leukotriene D4 receptor antagonist, has gained increasing consideration as a therapeutic agent for EoE. However, limited available information has shown that montelukast is not effective in reducing eosinophilic infiltration. Our paper aims at evaluating whether montelukast could be consider as a steroid-sparing therapy by assessing its efficacy in maintaining both clinical and histopathological remission achieved after topical corticosteroids in adult EoE patients. METHODS Eleven consecutively diagnosed adult EoE patients were prospectively studied. Esophageal biopsies were obtained before and after a 6-month treatment with fluticasone propionate 400 μg/twice a day. Immediately after that, montelukast 10 mg/day was instituted. A new endoscopy was foreseen after a new 3-month period, or as soon as the patients presented esophageal symptoms. Symptoms were assessed by using a questionnaire before and after fluticasone propionate treatment and after montelukast therapy. RESULTS Eosinophils density into the esophageal epithelium and lamina propria was significantly reduced after a 6-month treatment with topical steroids (P = 0.003) and increased to levels similar to baseline level into the first 3 months after treatment with montelukast. Baseline symptom scores significantly decreased after treatment with topical steroids (P = 0.003) and increased again after montelukast therapy, but baseline levels improved. CONCLUSIONS Montelukast was not efficient in maintaining the histopathological or clinical response achieved by topical steroids in adult EoE patients.

Abstract
Eosinophilic esophagitis (EE) is a recently recognized form of pan-esophagitis, which is characterized by the presence of at least 15 eosinophils per high power field on esophageal histology. EE is closely associated with atopic disorders and occurs predominantly in male patients. Young children are more likely to be sensitized to food allergens whilst aeroallergen sensitization predominates in older children and adults--a pattern reminiscent of the "atopic march". EE presents with a diverse range of gastrointestinal symptoms, including regurgitation, vomiting, feeding difficulties or refusal in infancy, in addition to dysphagia and food bolus impaction in older children and adults. The diagnosis may also be ascertained incidentally in patients undergoing gastroscopy for other suspected gastrointestinal conditions, such as gastroesophageal reflux disease or celiac disease. Complications mainly relate to subepithelial remodeling and fibrosis which may result in dysmotility, dysphagia and esophageal strictures. The proportion of EE patients at risk of these complications is unknown due to a paucity of data on the natural history of EE. There are only few randomized controlled trials assessing the efficacy of treatment modalities for EE, which currently either involve food allergen elimination or use of swallowed aerosolized corticosteroids. This article aims to discuss the complex issues of the diagnosis and long-term management that confront clinicians who care for children with EE.
