Abstract
Microscopic examination of esophageal biopsies is essential to diagnose eosinophilic esophagitis (EoE). Eosinophil inflammation is the basis for the diagnosis, but additional abnormalities may contribute to persistent symptoms and epithelial barrier dysfunction. Both peak eosinophil count and assessments of additional features should be included in pre-therapy and post-therapy pathology reports. Pathologic abnormalities identified in esophageal biopsies of EoE are reversible in contrast to esophageal strictures.

Abstract
Recent advances in rare disease research are accelerated by the work of consortia that have been supported by the National Institutes of Health. Development of such consortia rely on multidisciplinary relationships and engagement with patient advocacy groups, as well as the National Institutes of Health and industry and academic partners. In this rostrum we present the development of such a process that focuses on eosinophilic gastrointestinal diseases. Principal investigators, patient advocacy groups, research assistants, and trainees work together to perform natural history studies that promote clinical trial readiness tools, conduct clinical trials, train a new generation of investigators, and perform innovative pilot studies.

Abstract
BACKGROUND/AIMS Eosinophilic esophagitis (EoE) is gaining importance in the diagnosis of upper gastrointestinal (UGI) symptoms. Diagnosis is based on the clinical presentation of esophageal dysfunction and pathological findings in the absence of other causes of tissue eosinophilia. Our study was designed to evaluate EoE prevalence in patients with UGI symptoms in our locality (El-Minia, Egypt). METHODS This single-center, cross-sectional study recruited all patients with UGI symptoms who agreed for endoscopic evaluation. Esophageal biopsy samples were obtained and histological evaluation for the presence of eosinophils was performed for every patient. EoE was defined when at least 15 eosinophils were present in a single high-power field, in the absence of other causes of esophageal eosinophilia. RESULTS Between 2013 and 2015, 218 of 476 adult patients with UGI symptoms underwent upper endoscopy after giving consent. Among the 218 patients, only 4 (1.87%) had the diagnosis of EoE based on the presence of eosinophils in esophageal biopsies and exclusion of other causes of esophageal eosinophilia. Three patients with EoE presented mainly with dysphagia (75%) and/or other UGI symptoms, such as heartburn. CONCLUSIONS We observed a low prevalence of EoE in our locality. The diagnosis of EoE should be considered in patients with dysphagia and/or heartburn.

Abstract
PURPOSE OF REVIEW The goal of this review is to present and summarize studies on endoscopic findings in eosinophilic esophagitis (EoE), at diagnosis and in response to treatment, utilizing rigorous peer-reviewed literature in children wherever possible and to introduce a recently proposed standardized endoscopic evaluation system. RECENT FINDINGS Gold standard of diagnosis and assessment of response to therapy in EoE requires multiple endoscopies with biopsies for histology, which allows for observation of the esophageal mucosa. Typical endoscopic findings in patients with EoE include edema, exudate, furrowing, concentric rings, and strictures. Endoscopic findings have been broadly characterized into inflammatory features (edema, exudate, furrowing) and fibro-stenotic features (rings, stricture), in order to better reflect their underlying pathophysiology. Recent studies suggest strong correlations between endoscopic findings, through composite scoring systems, and histology, and therefore may be helpful as part of disease surveillance. The EoE Endoscopic Reference Score (EREFS) classification system was proposed in 2013 as an outcome metric for standardization in reporting endoscopic signs of EoE. Subsequent studies support utility of composite scoring, which utility has similarly been seen in pediatric treatment trials. Endoscopy in children provides insight into the natural history of EoE, with progressively more fibro-stenotic features occurring over time, giving an additional perspective into esophageal remodeling and response to treatment. Recognition of typical endoscopic findings at diagnosis and upon repeat endoscopy has allowed a clinician to monitor visual changes in esophageal mucosal health. Further studies to assess the role of composite scoring in disease management are needed.

Abstract
Eosinophilic gastrointestinal disorders (EGID) are characterized pathologically by excess eosinophils in mucosal biopsies of one or multiple sites in the gastrointestinal (GI) tract, simultaneously or sequentially. Eosinophilic esophagitis (EoE) is the best characterized EGID, and in most patients it is an abnormal immune-mediated response to food antigens. Current recommendations for diagnosis include signs and symptoms of esophageal dysfunction that do not respond to proton-pump inhibitor therapy, and esophageal biopsies that exhibit at least 15 intraepithelial eosinophils in at least one high power field (HPF). Therapy consists of swallowed glucocorticoids or dietary elimination. Eosinophilic gastritis (EG) is the second most common form of EGID, but like all forms of EGID except EoE consensus recommendations for either clinical or pathological diagnosis do not exist. EG may be associated clinically with peripheral blood eosinophilia, hypoalbuminemia, and anemia, and pathologically with marked expansion of lamina propria by dense eosinophilic infiltrates. Eosinophilic enteritis (EE) may be subdivided into eosinophilic duodenitis, eosinophilic jejunitis, and eosinophilic ileitis. Most investigators believe that EE rarely, if ever, exists as a solitary form of EGID and is encountered only in patients who have at least one other affected portion of the GI tract. Eosinophilic colitis (EC) is perhaps the most enigmatic EGID. Distinction of EC from inflammatory bowel disease may be problematic especially in children. Multiple possible etiologies for EGID include hypereosinophilic syndrome, drug reactions, etc. Currently, the only etiology that can be identified histologically is parasitic infestation, if a portion of an invasive parasite is found in mucosal biopsies. This review will provide guidelines for the pathologic diagnosis of the various forms of EGID.

Abstract
It is unknown if successful control of esophageal inflammation in eosinophilic esophagitis (EoE) decreases the need for subsequent esophageal dilation. We aimed to determine whether histologic response to topical steroid treatment decreases the likelihood and frequency of subsequent esophageal dilation. We conducted a retrospective cohort study. Patients with an incident diagnosis of EoE were included if they had an initial esophageal dilation, received topical steroids, and had a subsequent endoscopy with biopsies. The number of dilations performed in each group was determined, and histologic responders (<15 eos/hpf) were compared to nonresponders. The 55 EoE patients included (27 responders and 28 nonresponders) underwent a mean of 3.0 dilations over a median follow-up of 19 months. Responders required fewer dilations than nonresponders (1.6 vs. 4.6, P = 0.03), after adjusting for potential confounders. Despite undergoing significantly fewer dilations, responders achieved a similar increase in esophageal diameter with dilation (4.9 vs. 5.0 mm; P = 0.92). In EoE patients undergoing esophageal dilation at baseline, control of inflammation with topical steroids was associated with a 65% decrease in the number of subsequent dilations to maintain the same esophageal caliber. This suggests that inflammation control is an important goal in patients with fibrostenotic changes of EoE.

Abstract
Objectives: The role of eosinophilic esophagitis (EE) in aerodigestive tract disorders in children is underestimated and overlooked, primarily because of a lack of understanding of this disorder by otolaryngologists. We sought to better characterize the clinical presentation of EE in order to increase awareness among otolaryngologists. Methods: We retrospectively reviewed 71 children with biopsy-proven EE to determine the most common symptoms and laboratory findings that should increase the clinical suspicion of EE. Results: Dysphagia, food impaction, and emesis were the most common symptoms in children with EE. Asthma was the most common airway diagnosis. Rhinosinusitis was the most common otolaryngological diagnosis. Food allergy was present in 60% of the children tested. Eighty-three percent of the children with elevated immunoglobulin E levels had thick linear streaking or patchy white exudate of the esophagus seen on esophagoscopy. Other major medical comorbidities existed in more than half of the children with EE, of which psychiatric disorders and other disorders of the aerodigestive tract were the most common. Conclusions: Eosinophilic esophagitis may contribute to treatment failure in patients with common and complicated aerodigestive tract disorders. To encourage clinicians to avoid overlooking the diagnosis, we present an evaluative algorithm to increase the suspicion of this entity.

Abstract
BACKGROUND Phenotypes of eosinophilic esophagitis (EoE) are not well-characterized. OBJECTIVE To describe clinical features of patients with EoE with predefined phenotypes, determine predictors of these phenotypes, and make inferences about the natural history of EoE. DESIGN Retrospective study. SETTING Tertiary-care center. PATIENTS Incident EoE cases from 2001 to 2011 that met consensus diagnostic guidelines. INTERVENTION Review of records. MAIN OUTCOME MEASUREMENTS Endoscopic phenotypes, including fibrostenotic, inflammatory, or mixed. Other groups of clinical characteristics examined included atopy, level of esophageal eosinophilia, and age of symptom onset. Multinomial logistic regression assessed predictors of phenotype status. RESULTS Of 379 cases of EoE identified, there were no significant phenotypic differences by atopic status or level of eosinophilia. Those with the inflammatory phenotype were more likely to be younger than those with mixed or fibrostenotic (13 vs 29 vs 39 years, respectively; P < .001) and less likely to have dysphagia, food impaction, and esophageal dilation (P < .001 for all). The mean symptom length before diagnosis was shorter for inflammatory (5 vs 8 vs 8 years; P = .02). After multivariate analysis, age and dysphagia independently predicted phenotype. The odds ratio (OR) for fibrostenosis for each 10-year increase in age was 2.1 (95% CI, 1.7-2.7). The OR for dysphagia was 7.0 (95% CI, 2.6-18.6). LIMITATIONS Retrospective, single-center study. CONCLUSION In this large EoE cohort, the likelihood of fibrostenotic disease increased markedly with age. For every 10-year increase in age, the odds of having a fibrostenotic EoE phenotype more than doubled. This association suggests that the natural history of EoE is a progression from an inflammatory to a fibrostenotic disease.

Abstract
Eosinophilic esophagitis (EoE) is a clinicopathological condition characterized clinically by symptoms of esophageal dysfunction in the absence of acid reflux, with typical endoscopic findings and eosinophilia on biopsy. This article looks into the historical clinical recognition and description of EoE, in particular clinical manifestations, natural history, and epidemiology. Additionally, the evolution of endoscopic recognition and development of clinical trials are described: EoE is an isolated disease of the esophagus, although it is associated with other antigen-driven diseases such as asthma, rhinitis, and atopic dermatitis. After initial case reports which were mostly not typical of the disease state now described, the first case series were described in 1993 and 1994 in adults, and 1995 in children. Although rarely seen before 2000, the disease is now commonly recognized. Randomized clinical trials have now been performed on topical steroids, and on biological agents targeted against IL-5, IL-13, and other mediators. Therapy with dilatation may be best guided by measures of compliance and distensibility. Work is needed on biomarkers of the disease's severity and progression, and predictive indexes of complications. EoE is a relatively new disease of increasing importance. It represents an important diagnosis in patients with upper gastrointestinal symptoms and must be considered in all patients with dysphagia where the diagnosis is not certain and in all patients who have an assumed diagnosis of reflux but are not responding to standard reflux therapy.

Abstract
Eosinophilic esophagitis (EoE) is currently defined as an immune-mediated chronic esophageal disorder that is diagnosed using both clinical and pathologic information. A series of consensus diagnostic guidelines for EoE have brought a measure of consistency to the field, but in practice the diagnosis of EoE can be challenging. Typical clinical symptoms of EoE, including dysphagia, heartburn, and chest pain, can overlap with gastroesophageal reflux disease, which itself is a common indication for performing endoscopic evaluation. The endoscopic findings of EoE, such as esophageal rings, strictures, linear furrows, and white exudates, are not specific. Esophageal eosinophilia, the histologic hallmark of EoE, is also not pathognomonic and can be seen in a range of conditions. Further complicating the diagnosis of EoE is the newly recognized entity of proton pump inhibitor-responsive esophageal eosinophilia, a condition that must be excluded prior to confirming a diagnosis of EoE. This paper will review the current diagnostic criteria for EoE and discuss multiple clinical, endoscopic, and histologic pitfalls in making the diagnosis of EoE.

Abstract
Esophageal eosinophilia and eosinophilic esophagitis (EoE) are increasingly recognized and prevalent conditions, which now represent common clinical problems encountered by gastroenterologists, pathologists, and allergists. The study of EoE has become a dynamic field with an evolving understanding of the pathogenesis, diagnosis, and treatment. Although there are limited data supporting management decisions, clinical parameters are needed to guide the care of patients with eosinophilic-esophageal disorders. In this evidence-based review, recommendations developed by adult and pediatric gastroenterologists are provided for the evaluation and management of these patients. New terminology is emphasized, particularly the concepts of esophageal eosinophilia and proton-pump inhibitor-responsive esophageal eosinophilia (PPI-REE) as entities distinct from EoE.

Abstract
BACKGROUND & AIMS Endoscopic findings such as esophageal rings, strictures, narrow-caliber esophagus, linear furrows, white plaques, and pallor or decreased vasculature might indicate the presence of eosinophilic esophagitis (EoE). We aimed to determine the prevalence and diagnostic utility of endoscopic features of EoE. METHODS We conducted a systematic review and meta-analysis. PubMed, EMBASE, and gastrointestinal meeting abstracts were searched to identify studies that included more than 10 patients with EoE and reported endoscopic findings. Pooled prevalence, sensitivity, specificity, and predictive values were calculated using random- and mixed-effects models. RESULTS The search yielded 100 articles and abstracts on 4678 patients with EoE and 2742 without (controls). In subjects with EoE, the overall pooled prevalence was as follows: esophageal rings, 44%; strictures, 21%; narrow-caliber esophagus, 9%; linear furrows, 48%; white plaques, 27%; and pallor/decreased vasculature, 41%. Substantial heterogeneity existed among studies. Results from endoscopy examinations were normal in 17% of patients, but this number decreased to 7% when the analysis was limited to prospective studies (P < .05). Overall levels of sensitivity were modest, ranging from 15% to 48%, whereas levels of specificity were greater, ranging from 90% to 95%. Positive predictive values ranged from 51% to 73% and negative predictive values ranged from 74% to 84%. CONCLUSIONS There is heterogeneity among studies in the reported prevalence of endoscopic findings in patients with EoE, but in prospective studies at least 1 abnormality was detected by endoscopy in 93% of patients. The operating characteristics of endoscopic findings alone are inadequate for diagnosis of EoE. Esophageal biopsy specimens should be obtained from all patients with clinical features of EoE, regardless of the endoscopic appearance of the esophagus.

Abstract
Background Acid suppression with a proton pump inhibitor is standard treatment for gastroesophageal reflux disease and erosive esophagitis in adults and increasingly is becoming first-line therapy for children aged 1-17 years. We evaluated endoscopic healing of erosive esophagitis with esomeprazole in young children with gastroesophageal reflux disease and described esophageal histology. Methods Children aged 1-11 years with endoscopically or histologically confirmed gastroesophageal reflux disease were randomized to esomeprazole 5 or 10 mg daily (< 20 kg) or 10 or 20 mg daily (≥ 20 kg) for 8 weeks. Patients with erosive esophagitis underwent an endoscopy after 8 weeks to assess healing of erosions. Results Of 109 patients, 49% had erosive esophagitis and 51% had histologic evidence of reflux esophagitis without erosive esophagitis. Of the 45 patients who had erosive esophagitis and underwent follow-up endoscopy, 89% experienced erosion resolution. Dilation of intercellular space was reported in 24% of patients with histologic examination. Conclusions Esomeprazole (0.2-1.0 mg/kg) effectively heals macroscopic and microscopic erosive esophagitis in this pediatric population with gastroesophageal reflux disease. Dilation of intercellular space may be an important histologic marker of erosive esophagitis in children. Trial Registration D9614C00097; ClinicalTrials.gov identifier NCT00228527.

Abstract
BACKGROUND Eosinophilic esophagitis (EE) is a clinical entity that is recognized increasingly in children. The treatment of EE has been debated since its identification as a clinical entity separate from reflux esophagitis. We hypothesize that the treatment with a high-dose proton pump inhibitor (HDPPI) helps differentiate EE from noneosinophilic esophagitis (NEE). PATIENTS AND METHODS Retrospective review of 2221 patients who underwent esophagogastroduodenoscopy (EGD) with biopsies was undertaken. Sixty-nine patients had more than or equal to 15 eosinophils/high-power field (eos/HPF) in 1 or more esophageal levels. Of those, 36 were initially treated with HDPPI for 3 months followed by repeat EGD. Patients who demonstrated histologic response were classified as NEE. Patients with no histologic response were diagnosed as having EE and treated with HDPPI+swallowed fluticasone for 3 months followed by repeat EGD. RESULTS Of the 36 patients, histologic response was seen in 14 (39%) after treatment with HDPPI; 95% confidence interval (0.23-0.54). Swallowed fluticasone was added to the treatment of the 22 patients who did not show histologic response to HDPPI alone. Of those, 15 patients underwent repeat endoscopies. Seven patients were lost to follow-up or did not have repeated EGDs. Histologic response was observed in 9 of 15 (60%) patients. Of the nonresponders (6 of 15), 5 of 6 (83%) self-reported noncompliance with the swallowed fluticasone. Patients with more than or equal to 15 eos/HPF at all 3 levels (25 of 36) were less likely to respond to HDPPI alone and more likely to be categorized as EE (18 of 25), P=or<0.043. Symptomatically, 28 of 36 patients reported resolution of symptoms after HDPPI therapy alone, P=or<0.0001, regardless of histology. Visual endoscopic findings during the first and second EGDs did not show any significance in differentiating EE from NEE, P=0.625 and P=0.2405, respectively. CONCLUSIONS The study demonstrates that HDPPI can be used to help differentiate EE from NEE histologically. Moreover, patients with more than or equal to 15 eos/HPF at all 3 levels are less likely to respond to HDPPI than patients with more than or equal to 15 eos/HPF at fewer than 3 levels. Therefore, having more than or equal to 15 eos/HPF at 1 or 2 biopsy levels does not necessarily establish the diagnosis of EE. Symptomatic response to HDPPI does not correlate with histologic findings. Clinical management guided by EGD with biopsy helps distinguish patients with EE from those with NEE.

Abstract
PURPOSE OF REVIEW Eosinophilic esophagitis (EoE) is a relatively new chronic inflammatory disease of the esophagus. Novel aspects in the diagnosis and treatment of EoE are discussed in this review. RECENT FINDINGS Development of diagnostic guidelines consisting of symptoms as well as endoscopic and histopathologic criteria has improved the awareness of clinicians and the diagnosing of EoE. The clinically challenging discrimination of EoE from gastroesophageal reflux disease has become more obvious and has evoked the need for more individualized therapy options. Today, most patients with EoE can be treated successfully with topical corticosteroids. However, no convincing alternative treatment strategies exist for corticosteroid-refractory or corticosteroid-dependent patients. Interestingly, a single-nucleotide polymorphism in the eotaxin-3 gene has been linked to increased disease susceptibility for EoE. SUMMARY EoE is an emerging esophageal disease. A better understanding of the pathogenesis of this disorder would improve the clinical recognition and diagnostic ability and ultimately provide patients with more optimal treatment options.

Abstract
Eosinophilic esophagitis (EoE) is a chronic esophageal inflammatory disease of undetermined pathophysiology that results in dense mucosal eosinophilia and esophageal dysfunction. In childhood, vague symptoms associated with GERD and feeding difficulties are the first manifestations of EoE. Adults typically present with dysphagia and food impaction. No pathognomonic features have been identified for EoE and, therefore, its diagnosis must be made on both clinical and histological grounds. Effective treatments rely on steroids and dietary exclusions.

Abstract
BACKGROUND Recent developments may alter the approach to patients presenting with gastroesophageal reflux disease (GERD)-like symptoms. A newly proposed Montreal consensus definition of Barrett's esophagus includes all types of esophageal columnar metaplasia, with or without intestinal-type metaplasia. There is also increasing recognition of eosinophilic esophagitis (EE) in patients with GERD-like symptoms. OBJECTIVE To quantify the impact of these developments on a multiphysician general gastroenterology practice in a tertiary care medical centre. METHODS Medical charts of all patients having an initial gastroscopy for GERD-like symptoms over a one-year period were reviewed retrospectively, and audits of their endoscopic images and esophageal biopsies were performed. RESULTS Of the 353 study participants, typical symptoms of heartburn and acid reflux were present in 87.7% and 23.2%, respectively. Less commonly, patients presented with atypical symptoms (eg, dysphagia in 9.4%). At endoscopy, 26% were found to have erosive esophagitis and 12% had endoscopically suspected esophageal metaplasia. Histological evaluation was available for 65 patients. Ten of the 65 biopsied patients (15%) met traditional criteria for Barrett's esophagus (ie, exhibiting intestinal-type metaplasia), whereas 49 (75%) fulfilled the newly proposed consensus definition of Barrett's esophagus. Five patients (7.7%) met the study criteria for EE (more than 20 eosinophils per high-power field), four of whom had not been previously recognized. CONCLUSIONS Among patients presenting with GERD-like symptoms, the prevalence of Barrett's esophagus may increase markedly if the Montreal definition is adopted. In addition, growing awareness of EE may lead to an increase in the prevalence of this diagnosis. Prospective studies of the management implications of these findings are warranted.

Abstract
OBJECTIVES To determine predictors of histological response to proton pump inhibitor (PPI) therapy among children with significant esophageal eosinophilia (SEE), defined as >or=15 eosinophils per high powered field (eos/hpf) on esophageal mucosal biopsy (EMB). STUDY DESIGN Response to PPI therapy among children with SEE treated with PPI who underwent repeat EMB was studied retrospectively. Response was defined as <5 eos/hpf on repeat EMB. Characteristics of responders and nonresponders were analyzed. RESULTS Of 326 patients (ages 1 through 18 years) diagnosed with SEE over a 7-year period, 43 (mean age, 8.5 years; 67% males) met inclusion criteria. After PPI therapy, 17 patients (40%) were responders. There were no significant differences in demographics, presenting symptoms, endoscopic, or histological findings between responders and nonresponders. Among patients with 15 to 20 eos/hpf on EMB, 50% were responders; among patients with >20 eos/hpf on EMB, 29% were responders. Seven of 17 (41%) patients with abnormal pH monitoring and 5 of 11 (45%) patients with normal monitoring were responders. CONCLUSIONS Forty percent of patients with SEE demonstrated histological response to PPI therapy. None of the clinical characteristics evaluated predicted response, and response was not dependent on results of pH study. The role of PPI therapy in treating SEE warrants further prospective investigation.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EE) occurs in families. METHODS Record review confirmed patient kinship and provided clinical information. Slide review confirmed the diagnosis (threshold peak number > or = 24 eosinophils/high-power field). RESULTS Fifty-nine members (41 males, 18 females) of 26 families were 3 months to 47 years of age (mean age, 10.3 y) at diagnosis. The only recorded race was Caucasian. In 4 families a parent of an affected male had EE. The most common complaint at diagnosis was dysphagia (68% of patients). Endoscopy showed esophageal mucosal furrows (93% of patients) and exudates (44%). Fifty-one percent had asthma. Skin prick tests to food and aeroallergens were positive in 76% and 71%, respectively. Familial EE characteristics (clinical, endoscopic, pathologic, and global esophageal transcript expression profile analysis) were similar to sporadic EE, except among patients with mucosal furrows: familial patients had lower peak eosinophil counts in the distal esophagus (P = .03) compared with sporadic patients. The basic characteristics of EE (eg, eosinophil levels, rate of atopy) did not vary with patient age. By using genome-wide microarray analysis, no significant differences (P < .05, false-discovery rate) were observed between familial and sporadic EE. Among all patients, chest pain was more common in females (P = .02), and thickened mucosa was more common in males (P = .006). CONCLUSIONS These data support a familial pattern of inheritance of EE and a pathogenesis shared with sporadic EE. EE should be considered in symptomatic family members of patients who have EE.

Abstract
The pathology of eosinophilic esophagitis (EE) when fully developed in humans is highly characteristic and readily discriminated from the histology of the normal esophagus. The histologic alterations are not pathognomonic for any of the multiple causes of EE, and the correct diagnosis can be made only if the histology is correlated with clinical findings. The histology of the normal esophagus is reviewed and contrasted with the findings in EE. The characteristic findings in EE are illustrated. Selected research in humans and animal models pertinent to EE are briefly reviewed.

Abstract
During the last decade, clinical practice saw a rapid increase of patients with esophageal eosinophilia who were thought to have gastroesophageal reflux disease (GERD) but who did not respond to medical and/or surgical GERD management. Subsequent studies demonstrated that these patients had a "new" disease termed eosinophilic esophagitis (EE). As recognition of EE grew, so did confusion surrounding diagnostic criteria and treatment. To address these issues, a multidisciplinary task force of 31 physicians assembled with the goal of determining diagnostic criteria and making recommendations for evaluation and treatment of children and adults with suspected EE. Consensus recommendations were based upon a systematic review of the literature and expert opinion. EE is a clinicopathological disease characterized by (1) Symptoms including but not restricted to food impaction and dysphagia in adults, and feeding intolerance and GERD symptoms in children; (2) > or = 15 eosinophils/HPF; (3) Exclusion of other disorders associated with similar clinical, histological, or endoscopic features, especially GERD. (Use of high dose proton pump inhibitor treatment or normal pH monitoring). Appropriate treatments include dietary approaches based upon eliminating exposure to food allergens, or topical corticosteroids. Since EE is a relatively new disease, the intent of this report is to provide current recommendations for care of affected patients and defining gaps in knowledge for future research studies.

Abstract
Eosinophilic oesophagitis is characterised by age-dependent symptoms mimicking gastrooesophageal reflux disease, a distinct endoscopic appearance and a histological picture with extensive infiltration of eosinophils in the oesophageal mucosa. Eosinophilic oesophagitis is more frequently seen in males, and patients often belong to the paediatric or adolescence age groups. The exact prevalence of eosinophilic oesophagitis is unknown, but it has been suggested that the United States has a higher prevalence than Europe. Several treatment algorithms have been suggested, including elemental diets, oral steroids, inhaled (swallowed) steroids, and leucotriene receptor antagonists. Detailed information on the eosinophilic inflammatory processes in the oesophageal mucosa was initially obtained from animal models, in particular with regard to the role of interleukin-5 and the chemokine eotaxin-1 in eosinophilic recruitment. Studies have suggested a cytotoxic effect of eosinophilic degranulation products on nerve fibers in the gastric/intestinal mucosa, implicating a direct effect of allergic inflammation on gastrointestinal motility. Human studies recently have emphasized the role of eotaxin-3 and identified a single nucleotide polymorphism probably related to disease susceptibility.

Abstract
Allergic eosinophilic esophagitis is an increasingly recognized disease in various parts of the world. The clinical presentation mimics other gastrointestinal diseases, especially gastroesophageal reflux disease, making endoscopic examination and histological evaluation of esophageal mucosal biopsies crucial to accurate diagnosis. The pathogenesis likely involves allergen-initiated, TH2-dependent, IL-5 mediated infiltration of eosinophilis into the esophageal mucosa. Therapies currently favored include dietary modifications and use of corticosteroids.

Abstract
BACKGROUND Eosinophilic oesophagitis is a clinicopathological disease affecting both children and adults that is characterized by symptoms of gastro-oesophageal reflux disease (feeding refusal, vomiting, heartburn, dysphagia and food impaction) and dense oesophageal eosinophilia both of which are unresponsive to proton pump inhibition. AIM To present a review of the recent literature examining the pathogenesis and treatments of eosinophilic oesophagitis. METHODS We performed a PubMed search for eosinophilic oesophagitis, pathogenesis and treatments. RESULTS Translational and basic studies suggest that this disease is sparked by food or by aeroallergens. To date, effective treatments include systemic/topical corticosteroids, specific food elimination or an elemental diet. While several studies identified oesophageal strictures as potential complications of unbridled eosinophilia, the natural history of the disease is still not certain. Recent studies suggest a role for interleukin-5 and eotaxin-3 in the pathogenesis of eosinophilic oesophagitis and suggest an impact of future targeted therapeutic agents. CONCLUSIONS Eosinophilic oesophagitis represents a immune-mediated disease of undetermined pathogenesis. While many patients develop clinicopathological findings following ingestion of foods, others do not. Natural history studies will be critical to defining future treatment paradigms.

Abstract
Eosinophilic esophagitis (EE) is characterized by eosinophilic infiltration of the esophageal mucosa and results in clinical signs and symptoms that may be indistinguishable from those of gastroesophageal reflux disease (GERD). While demographic, clinical, and endoscopic features may be suggestive of EE, esophageal biopsy with tissue eosinophils averaging 24 per 400 x microscopic field remains the most specific diagnostic criterion. Previously rare, EE has been diagnosed in adults and children with increased frequency over the last decade; it appears to be a chronic disease and has a yearly incidence approximating 1:10,000 in the pediatric population. Dietary and respiratory antigen exposure with subsequent production of inflammatory chemokines is essential for development of EE in animal models of the disease. In humans, glucocorticoids and elimination of relevant dietary antigens have proved efficacious treatments for EE, resolving the disease at the mucosal level. Other therapies, including montelukast, partial dietary elimination, and bouginage have reduced symptoms without affecting mucosal inflammation. Evidence-based guidelines for the management of EE are not currently available. Current medical practice involving the management of reflux merits awareness and understanding of this emerging mimic. We present a review of the current understanding of this disorder.

Abstract
OBJECTIVES Basal cell hyperplasia of the esophageal epithelium is a frequent finding in children with histological evidence of esophagitis. The aim of this study was to compare the severity of basal cell hyperplasia in gastroesophageal reflux vs eosinophilic esophagitis. METHODS A cohort of pediatric patients who underwent same-day endoscopy with esophageal biopsy and 24-hour esophageal pH monitoring was divided into groups based on endoscopic and pH monitoring findings. Basal cell hyperplasia was defined as normal (< or = 25% of esophageal epithelial height), mild (26%-50%), moderate (51%-75%) or severe (> 75%). The severity of basal cell hyperplasia in patients with abnormal pH monitoring studies, both with and without endoscopic abnormalities of the esophagus, was compared with the severity in patients with eosinophilic esophagitis. RESULTS Twenty-seven children with abnormal pH monitoring were identified. Of these 27 children, 11 had endoscopic findings consistent with reflux esophagitis. Thirty patients with eosinophilic esophagitis were identified. Patients with eosinophilic esophagitis had significantly increased severity (P < 0.001) of basal cell hyperplasia (87% severe, 3% moderate, 3% mild, 7%, normal) than patients with abnormal esophageal pH monitoring alone (11% severe, 4% moderate, 15% mild, 70% normal) or in combination with endoscopic abnormalities (18% severe, 9% moderate, 18% mild, 55% normal). CONCLUSIONS Basal cell hyperplasia is more severe in children with eosinophilic esophagitis than in those with reflux esophagitis. The finding of basal cell hyperplasia is a powerful clue into the underlying etiology of pediatric esophagitis and, along with epithelial eosinophil count, can be used as information to guide therapy.

Abstract
OBJECTIVES Allergic eosinophilic esophagitis (AEE) is characterized by intense eosinophilic inflammation of the esophageal mucosa. Cysteinyl leukotrienes (CysLT) are eosinophil chemoattractants. We studied CysLT levels in esophageal mucosa of children with AEE and controls. METHODS CysLT levels (pg CysLT/microg protein) were quantified by Enzyme-linked Immunosorbent Assay (ELISA) on endoscopically obtained esophageal mucosal biopsies. RESULTS Twelve children with AEE (eight boys, mean age 6.6 yr, range 1.0-14.5 yr) and 10 controls (six boys, mean age 9.56 yr, range 1.08-15.08 yr) were enrolled. None were on anti-LT or corticosteroid therapy. All controls had histologically normal mucosal biopsies of the esophagus, stomach, and duodenum. Patients with AEE had intense eosinophilic inflammation of the esophageal mucosa (mean 39 eosinophils/hpf, range 15-70 eosinophils/hpf) and a normal 24-h pH probe study. CysLT levels were similar between the two groups: mean levels were 12.44 (median 10.87, range 2.54-28.29) in AEE patients and 9.52 (median 9.26, range 1.71-21.64) in controls. CysLT levels did not correlate with the degree of esophageal eosinophilic inflammation. Incidentally, five patients with eosinophilic gastroduodenitis, in addition to esophagitis, were enrolled; their CysLT levels were statistically higher than those of controls. CONCLUSIONS This is the first study to examine CysLT levels in esophageal mucosal biopsies of children with AEE and normal children. CysLT levels in AEE patients are similar to those in controls, and independent of the severity of inflammation. While this would argue against the use of CysLT antagonists in the treatment of AEE, further studies into the expression of the CysLT receptor itself are needed.

Abstract
Eosinophilic esophagitis has rapidly become a recognized entity causing dysphagia in young adults. This review summarizes the current knowledge of eosinophilic esophagitis including the epidemiology, clinical presentation, diagnostic criteria, pathophysiology, treatment, and prognosis. An extensive search of PubMed/Medline (1966-December 2005) for available English literature in humans for eosinophilic esophagitis was completed. Appropriate articles listed in the bibliographies were also attained. The estimated incidence is 43/105 in children and 2.5/105 in adults. Clinically, patients have a long history of intermittent solid food dysphagia or food impaction. Some have a history of atopy. Subtle endoscopic features may be easily overlooked, including a “feline” or corrugated esophagus with fine rings, a diffusely narrowed esophagus that may have proximal strictures, the presence of linear furrows, adherent white plaques, or a friable (crepe paper) mucosa, prone to tearing with minimal contact. Although no pathologic consensus has been established, a histologic diagnosis is critical. The accep-ted criteria are a dense eosinophilic infiltrate (>20/high power field) within the superficial esophageal mucosa. In contrast, the esophagitis associated with acid reflux disease can also possess eosinophils but they are fewer in number. Once the diagnosis is established, treatment options may include specific food avoidance, topical corticosteroids, systemic corticosteroids, leukotriene inhibitors, or biologic treatment. The long-term prognosis of EE is uncertain; however available data suggests a benign, albeit inconvenient, course. With increasing recognition, this entity is taking its place as an established cause of solid food dysphagia.

Abstract
OBJECTIVES We studied the expression of cytokines and inflammatory cells in normal and inflamed esophageal mucosa of children with the aim of furthering our understanding of the pathophysiology of allergic eosinophilic esophagitis (AEE). METHODS Controls and AEE patients (>or=15 eosinophils/high-power field on esophageal mucosal biopsies) between the ages of 1 and 18 years were recruited. Esophageal biopsies were obtained for histologic examination, immunohistochemical studies, and cytokine analysis. RESULTS Eight controls (4 males; mean age 9.99 years) and 11 AEE patients (8 males; mean age 7.15 years) were studied. mRNA expression of interferon (IFN)-gamma, interleukin (IL)-4, IL-5, IL-13, eotaxin-1, eotaxin-2, eotaxin-3, and RANTES was studied. IFN-gamma and IL-5 expressions were significantly up-regulated in AEE patients compared with controls. Expressions of IL-4 and IL-13 were similar between AEE patients and controls. Eotaxin-1 expression was significantly up-regulated in AEE patients, whereas eotaxin-2 was up-regulated in controls. Expression of RANTES and eotaxin-3 was similar between the two groups. There was increased staining for mast cells in AEE patients compared with controls. CONCLUSIONS Our data suggests that AEE is primarily an IL-5 selective TH2 response, with a possible TH1 component, and a differential role of eosinophilic chemoattractants. The role of mast cells in the pathogenesis of AEE needs additional study.

Abstract
PURPOSE OF REVIEW Previously perceived as an anomaly, eosinophilic esophagitis is now frequently diagnosed by both pediatric and adult specialists including gastroenterologists, allergists, pathologists, and otolaryngologists. Research efforts initially focused on characterization of the clinical, endoscopic, and histologic features of this disorder. In the last 3 years, the research focus has evolved into understanding its immunologic and demographic features as well as the development of efficacious therapies. RECENT FINDINGS Population-based demographic studies have documented the unique epidemiologic parameters of eosinophilic esophagitis, some of its natural history, and its increasing frequency. Basic research efforts have identified cytokines relevant toward development of eosinophilic esophagitis, including interleukin-5 and interleukin-13. Clinical efforts have established the efficacy of dietary and medical treatments. Some treatments result in symptomatic improvement with ongoing inflammation, so a debate is ensuing over the long-term effect of asymptomatic esophageal inflammation. SUMMARY Understanding of eosinophilic esophagitis has evolved to a point at which patients can be appropriately diagnosed and initially treated; however, a paucity of long-term outcome data prevents the creation of uniform recommendations for the clinical care of patients with eosinophilic esophagitis.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EoE) is a disorder characterized by a severe, isolated eosinophilic infiltration of the esophagus unresponsive to aggressive acid blockade but responsive to the removal of dietary antigens. We present information relating to our 10-year experience in children diagnosed with EoE. METHODS We conducted a retrospective study between January 1, 1994, and January 1, 2004, to evaluate all patients diagnosed with EoE. Clinical symptoms, demographic data, endoscopic findings, and the results of various treatment regimens were collected and evaluated. RESULTS A total of 381 patients (66% male, age 9.1 +/- 3.1 years) were diagnosed with EoE: 312 presented with symptoms of gastroesophageal reflux; 69 presented with dysphagia. Endoscopically, 68% of patients had a visually abnormal esophagus; 32% had a normal-appearing esophagus despite a severe histologic esophageal eosinophilia. The average number of esophageal eosinophils (per 400 x high power field) proximally and distally were 23.3 +/- 10.5 and 38.7 +/- 13.3, respectively. Corticosteroids significantly improved clinical symptoms and esophageal histology; however, upon their withdrawal, the symptoms and esophageal eosinophilia recurred. Dietary restriction or complete dietary elimination using an amino acid-based formula significantly improved both the clinical symptoms and esophageal histology in 75 and 172 patients, respectively. CONCLUSIONS Medications such as corticosteroids are effective; however, upon withdrawal, EoE recurs. The removal of dietary antigens significantly improved clinical symptoms and esophageal histology in 98% of patients.

Abstract
Eosinophilic gastroenteritis despite its uncommon occurrence is one of the most important primary eosinophilic gastrointestinal disorders, and most commonly presents with abdominal pain. The terminology is, however, misleading because all levels of the gastrointestinal tract from the esophagus to the rectum may be affected. A history of atopy and allergies is present in 25-75% cases. The heterogeneity in the clinical presentations of EG is determined by the site and depth of eosinophilic infiltration. Eosinophilic intestinal inflammation also occurs secondarily in the gastrointestinal tract in inflammatory bowel disease, autoimmune diseases, as reactions to medications, infections, hypereosinophilia syndrome, and after solid organ transplantation. Recent investigations providing an insight into the pathogenesis of eosinophilic gastroenteritis support a critical role for allergens, eosinophils, Th-2 type cytokines, and eotaxin in mediating eosinophilic inflammation. The diagnosis is confirmed by demonstrating prominent tissue eosinophilia on histopathology. Treatment recommendations based on data extrapolated from retrospective, uncontrolled studies, and expert opinion support the use of restricted diets, corticosteroids, leukotriene receptor antagonists, and mast cell stabilizers. Many unanswered questions remain with regard to the natural history, optimal duration of therapy, safer steroid-sparing long-term treatment agents, and the means of reliable and non-invasive follow-up.

Abstract
Eosinophilic esophagitis (EE) is rapidly emerging as a distinct disease entity in both pediatric and adult gastroenterology. The typical clinical presentation includes solid food dysphagia in young men who have an atopic predisposition. Food impaction necessitating endoscopic intervention is common. EE should be suspected, in particular, in patients with unexplained dysphagia or those with no response to antacid or anti-acid secretory therapy. Careful endoscopic and radiographic examinations reveal furrows, corrugations, rings, whitish plaques, fragile crêpe paper-like appearance, and a small-caliber esophagus. Mucosal erosion in the distal esophagus, characteristic to reflux esophagitis, is absent in EE. Marked eosinophil infiltration in the esophageal epithelia (>20 eosinophils per high-power field) is the diagnostic hallmark. Food antigens and aeroallergens may play a role in the pathogenesis of EE. The mechanisms may be dependent or independent of immunoglobulin E. Elimination diets, systemic and topical corticosteroids, leukotriene receptor antagonists, and, most recently, an anti-interleukin-5 monoclonal antibody have been used to treat EE. EE likely represents another example of eosinophil-associated inflammation of epithelia at the interface between external and internal milieu, similar to bronchial asthma and atopic dermatitis. This review summarizes recent progress in the diagnosis and management of EE and discusses future research directions.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EE) is a recently recognized clinical disorder that is understood poorly. We aimed to determine the efficacy of swallowed fluticasone propionate on the immunopathologic features associated with EE. METHODS A retrospective analysis was performed on 20 pediatric patients with EE. Inclusion criteria specified a peak eosinophil density of > or =24 cells per 400x field in the esophagus and treatment with swallowed fluticasone between 2 endoscopic assessments. Histologic specimens were examined for eosinophil and CD8(+) lymphocyte infiltration, papillary lengthening, and proliferation of the basal layer as determined by monoclonal anti-Ki-67 (MIB-1) antibody staining. RESULTS The mean time interval between endoscopic assessments was 4.8 months. The patients were divided equally between allergic and nonallergic groups based on the results of skin-prick testing. All of the nonallergic patients responded to fluticasone propionate. The endoscopic appearance of the mucosa improved and microscopic evaluation showed markedly reduced eosinophil infiltration, reduced basal layer hyperplasia documented by a reduced number of MIB-1(+) cells, and a reduced number of CD8(+) lymphocytes. However, allergic patients were relatively refractory to therapy; 20% had a partial response, whereas 20% had no detectable improvement. Esophageal eosinophil levels before and after therapy in all patients strongly correlated with the level of epithelial cell proliferation as measured by MIB-1 staining. CONCLUSIONS Collectively, these results suggest that patients treated with swallowed fluticasone have improved endoscopic, histologic, and immunologic parameters associated with EE. However, patients with identifiable allergies who fail dietary elimination may have a blunted response to treatment.

Abstract
BACKGROUND White specks in the esophageal mucosa have been observed in children with eosinophilic esophagitis. The aim of this study was to determine the relationship between white specks in the esophageal mucosa and allergic (non-reflux) eosinophilic esophagitis. METHODS Endoscopic data, pH probe results, and histopathology reports for children with esophageal endoscopic abnormalities seen during a 17-month period were reviewed. Eosinophilic esophagitis was grouped according to the number of eosinophils per high power field (non-allergic, <15 eosinophils/high power field; allergic, > or =15 eosinophils/high power field). RESULTS Of 1041 endoscopies performed during the study period, 153 revealed evidence of eosinophilic esophagitis. Of these 153, 61 had fewer than 15 eosinophils/high power field and 92 had 15 or more eosinophils/high power field. At 31 of the 153 procedures, white specks were noted in the esophageal mucosa. The sensitivity of white specks in the esophageal mucosa for allergic eosinophilic esophagitis was only 30%, but the specificity was 95%. pH probe testing was performed in 21 patients with white specks and was normal in all. CONCLUSIONS This report describes a new endoscopic finding associated with allergic eosinophilic esophagitis in children. Eosinophilic esophagitis tends to be severe when white specks are present (> or =15 eosinophils/high power field) and is not associated with pathologic gastroesophageal reflux, as demonstrated by pH probe testing.

Abstract
OBJECTIVES Children occasionally have dysphagia in the absence of an apparent primary cause. Esophageal eosinophilia is sometimes seen in these patients at the time of upper endoscopy but its significance is not clear. Although eosinophilia is regarded by some as a histologic hallmark of childhood reflux esophagitis, it may in fact signal a primary eosinophilic esophagitis in children with dysphagia. Our aim was to evaluate esophagitis, acid reflux determined by pH probe, and esophageal eosinophilia in children with the primary complaint of dysphagia. METHODS A retrospective study was performed in 42 children, admitted for investigation of dysphagia, in whom no primary cause could be found. Twenty-one children (mean age +/- SD, 10.1 +/- 4.0 years) had esophageal eosinophilia and 21 children (8.3 +/- 4.7 years) did not. Clinical, endoscopic, manometric and esophageal pH parameters in these two groups were compared. RESULTS Patients with esophageal eosinophilia were more often male (p<0.01) with a history of allergy (p<0.001) and food bolus obstruction (p<0.05) requiring endoscopic removal. Their esophageal mucosa appeared wrinkled and thickened at endoscopy with basal cell proliferation, and large numbers of eosinophils in esophageal mucosal biopsies. Continuous esophageal pH records and motility studies, when obtained, were similar in both groups and were within normal values. CONCLUSION Children with dysphagia who have esophageal eosinophilia are unlikely to have pathologic gastroesophageal reflux.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EE) shares symptoms with gastroesophageal reflux disease but has distinctive pathologic features and unknown immunopathology. Treatments with antigen restriction or systemic immunosuppression pose problems with compliance and side effects. Topically applied steroids offer an attractive alternative treatment. The aims of this study were to determine the immunopathologic features of EE and the effectiveness of antigen-specific diet restriction (DR) and topical immunosuppression. METHODS A prospective trial was conducted examining the impact of DR and swallowed fluticasone propionate (FP) on pediatric patients with EE. Clinicopathologic features, including immunohistochemical analysis of the esophageal mucosa, were measured before and after treatment. RESULTS Immunohistochemical analysis of 11 prospectively identified children showed a significantly greater number of mucosal CD3 and CD8 lymphocytes, as well as CD1a antigen-presenting cells compared with normal controls. DR did not induce clinical improvement in any patients, whereas all children who completed treatment with FP had resolution of symptoms. Posttreatment analysis of proximal and distal esophageal mucosa showed a significant reduction in the number of eosinophils, as well as CD3(+) and CD8(+) lymphocytes compared with pretreatment sections. CONCLUSIONS EE is characterized by immunologically active esophageal mucosa. FP, not DR, effectively relieves symptoms. FP significantly reduces mucosal inflammation associated with EE.

Abstract
Gastroesophageal reflux (GER), defined as passage of gastric contents into the esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER. The GER Guideline Committee, consisting of a primary care pediatrician, two clinical epidemiologists (who also practice primary care pediatrics) and five pediatric gastroenterologists, based its recommendations on an integration of a comprehensive and systematic review of the medical literature combined with expert opinion. Consensus was achieved through Nominal Group Technique, a structured quantitative method. The Committee examined the value of diagnostic tests and treatment modalities commonly used for the management of GERD, and how those interventions can be applied to clinical situations in the infant and older child. The guideline provides recommendations for management by the primary care provider, including evaluation, initial treatment, follow-up management and indications for consultation by a specialist. The guideline also provides recommendations for management by the pediatric gastroenterologist. This document represents the official recommendations of the North American Society for Pediatric Gastroenterology and Nutrition on the evaluation and treatment of gastroesophageal reflux in infants and children. The American Academy of Pediatrics has also endorsed these recommendations. The recommendations are summarized in a synopsis within the article. This review and recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the management of all patients with this problem.

Abstract
Eosinophilic esophagitis is a clinicopathologic disease characterized by 1) persistent upper intestinal symptoms despite the patient's use of gastric acid blockade and 2) large numbers of eosinophils in the squamous epithelium of the esophagus. This disease is increasing in frequency and the exact etiologic agent(s) remain elusive. The major importance of identifying eosinophilic esophagitis is that affected patients are receiving fundoplication for persistent symptoms when, in fact, corticosteroids or diet restriction is the treatment of choice.

Abstract
OBJECTIVES Eosinophilic esophagitis, previously confused with esophageal inflammation due to gastroesophageal reflux, has recently begun to be distinguished from it. We undertook this analysis of our large series of children with the condition to clarify its spectrum: its presenting symptoms; its relation to allergy, respiratory disease, and reflux; its endoscopic and histological findings; and its diagnosis and therapy. METHODS We analyzed the details of our clinical series of 30 children with eosinophilic esophagitis, defining it as > or =5 eosinophils per high power field in the distal esophageal epithelium. Retrospective chart review was supplemented by prospective, blinded, duplicate quantitative evaluation of histology specimens, and by telephone contact with some families to clarify subsequent course. Presentation and analysis of the series as a whole is preceded by a case illustrating a typical presentation with dysphagia and recurrent esophageal food impactions. RESULTS Presenting symptoms encompass vomiting, pain, and dysphagia (some with impactions or strictures). Allergy, particularly food allergy, is an associated finding in most patients, and many have concomitant asthma or other chronic respiratory disease. A subtle granularity with furrows or rings is newly identified as the endoscopic herald of histological eosinophilic esophagitis. Histological characteristics include peripapillary or juxtaluminal eosinophil clustering in certain cases. Association with eosinophilic gastroenteritis occurs, but is not common. Differentiation from gastroesophageal reflux disease is approached by analyzing eosinophil density and response to therapeutic trials. Therapy encompasses dietary elimination and anti-inflammatory pharmacotherapy. CONCLUSION Awareness of the spectrum of eosinophilic esophagitis should promote optimal diagnosis and treatment of this elusive entity, both in children and in adults.
