Abstract
OBJECTIVE To evaluate the accuracy of the modified CT severity index (MCTSI) in predicting the severity of acute pancreatitis and to prognosticate the clinical outcomes. METHODS AND MATERIALS The study was conducted at a tertiary health center between January 2021 and June 2023. A total of 150 consecutive patients with clinical/laboratory features suggestive of acute pancreatitis were included in the study and underwent a contrast-enhanced CT scan within 24 hours of admission. Based on their MCTSI score, these patients had conservative or surgical/endoscopic treatment. Clinical outcomes were assessed in terms of recovery, development of complications, or death. The receiver operating characteristic curve and descriptive statistics were computed to determine the sensitivity and specificity. The data were analyzed using SPSS version 16 software (SPSS Inc., Chicago, IL), and an attempt was made to evaluate the accuracy of MCTSI in predicting these clinical outcomes. RESULTS The mean age of patients in our study was 49.21 ± 11.02 years. Out of the 150 included patients, 103 were men and 47 were women. Compared to 11.68% of severe acute pancreatitis patients who died, 88.32% recovered. The area under the curve was determined as 0.865, based on which the MCTSI score predicted acute pancreatitis clinical outcome with 64% sensitivity and 92% specificity. The MCTSI demonstrated value in predicting clinical outcomes with a p-value of 0.043 ± 0.012 (p < 0.05) in the recovered patients while p = 0.032 ± 0.012 for patients who succumbed. The p-value for MCTSI in predicting complications was p = 0.0012 ± 0.0008 (p < 0.05). CONCLUSION Our study was able to demonstrate the high level of accuracy of the MCTSI score in predicting complications and clinical outcomes, especially in patients with severe acute pancreatitis. The MCTSI serves as a valuable asset in the preliminary evaluation of acute pancreatitis, thereby facilitating appropriate management.

Abstract
BACKGROUND AND AIMS Ultrasonography has shown that eosinophils accumulate in each segment of the esophageal mucosa in human EoE, ultimately promoting esophageal motility dysfunction; however, no mechanistic evidence explains how or why this accumulation occurs. METHODS Quantitative PCR, ELISA, flow cytometry, immunostaining, and immunofluorescence analyses were performed using antibodies specific to the related antigens and receptors. RESULTS In deep esophageal biopsies of EoE patients, eosinophils and mast cells accumulate adjacent to nerve cell-derived VIP in each esophageal segment. qRT-PCR analysis revealed five- to sixfold increases in expression levels of VIP, CRTH2, and VAPC2 receptors and proteins in human blood- and tissue-accumulated eosinophils and mast cells. We also observed a significant correlation between mRNA CRTH2 levels and eosinophil- and nerve cell-derived VIPs in human EoE (p < 0.05). We provide evidence that eosinophil and mast cell deficiency following CRTH2 antagonist treatment improves motility dysfunction in a chronic DOX-inducible CC10-IL-13 murine model of experimental EoE. CONCLUSIONS CRTH2 antagonist treatment is a novel therapeutic strategy for inflammatory cell-induced esophageal motility dysfunction in IL-13-induced chronic experimental EoE.

Abstract
Elevated levels of interleukin (IL)-18 have been reported in a number of allergic diseases. We recently reported that IL-18 in the blood and IL-18Rα mRNA in the oesophagus are induced during human eosinophilic oesophagitis (EoE). Additionally, we earlier showed that invariant natural killer T (iNKT) cells are critical to EoE pathogenesis; however, the mechanism of iNKT cell activation in EoE is not well understood. Therefore, the current study focused on the hypothesis that allergen-induced IL-18 may have an important role in iNKT cell-mediated EoE pathogenesis. We first validated the human EoE findings of IL-18 in experimental EoE by examining blood levels of IL-18 and oesophageal IL-18Rα mRNA levels in aeroallergen- and food allergen-induced experimental mouse models of EoE. We demonstrate that blood IL-18 protein and oesophageal IL-18Rα mRNA are induced in the mouse model of EoE and that IL-18Rα is expressed by iNKT cells in the oesophagus. Intranasal delivery of rIL-18 induced both mast cells and eosinophilic inflammation in the oesophagus in a time- and dose-dependent manner. To establish the significance of IL-18 in EoE pathogenesis, we examined DOX-inducible rtTA-CC10-IL-18 bitransgenic mice that induce IL-18 protein expression in the oesophagus. Our analysis indicated that induction of IL-18 in these mice resulted in the development of many of the characteristics of EoE, including oesophageal intraepithelial eosinophilia, increased mast cells, oesophageal remodelling and fibrosis. The current study provides evidence that IL-18 may induce iNKT cell activation to release the eosinophil-activating cytokine IL-5, as IL-5-deficient mice and iNKT cell-deficient (CD1d null) mice do not induce EoE in response to intranasal IL-18 challenge. Taken together, these findings provide evidence that allergen-induced IL-18 has a significant role in promoting IL-5- and iNKT-dependent EoE pathogenesis.

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.

Abstract
IL-18 is induced in food allergy and EoE is food allergen-induced disease. Therefore, we tested the hypothesis whether IL-18 is involved in food allergen-induced EoE pathogenesis. Accordingly, we examined normal SPT+ and SPT- EoE patient blood and biopsy samples for IL-18, IL-18Rα, ICAM and VCAM expression. Herein, we show increased IL-18 level is highly significant in food allergen SPT+ compared to SPT- EoE patients. We also report that IL-18Rα+ cells and mRNA levels are induced in the esophageal biopsies of EoE patients and blood IL-18 levels correlate with esophageal eosinophilia (P<0.01). Additionally, we report that the levels of esophageal eosinophil and mast cells correlate with ICAM expression in human EoE. Mechanistically, we show that IL-18 in vitro stimulates iNKT cells and endothelial cells and induce eosinophil active cytokines IL-5 and IL-13. We provide the evidence that IL-18 is critical cytokine involved in activation of iNKT cells and ICAM in promoting human EoE.

Abstract
Esophageal atresia (EA) is defined as a discontinuity of the lumen of the esophagus repaired soon after birth. Dysphagia is a common symptom in these patients, usually related to stricture, dysmotility or peptic esophagitis. We present 4 cases of patients with EA who complained of dysphagia and the diagnosis of Eosinophilic esophagitis (EoE) was made, ages ranging from 9 to 16 years. Although our patients were on acid suppression years after their EA repair, they presented with acute worsening of dysphagia. Esophogastroduodenoscopy and/or barium swallow did not show stricture and biopsies revealed elevated eosinophil counts consistent with EoE. Two of 4 patients improved symptomatically with the topical steroids. It is important to note that all our patients have asthma and 3 out of 4 have tested positive for food allergies. One of our patients developed recurrent anastomotic strictures that improved with the treatment of the EoE. A previous case report linked the recurrence of esophageal strictures in patients with EA repair with EoE. Once the EoE was treated the strictures resolved. On the other hand, based on our observation, EoE could be present in patients without recurrent anastomotic strictures. There appears to be a spectrum in the disease process. We are suggesting that EoE is a frequent concomitant problem in patients with history of congenital esophageal deformities, and for this reason any of these patients with refractory reflux symptoms or dysphagia (with or without anastomotic stricture) may benefit from an endoscopic evaluation with biopsies to rule out EoE.

Abstract
Eosinophilic esophagitis is a chronic immune/antigen mediated inflammatory disease of the esophagus. It comprises a separate entity of increasing incidence and prevalence in children and adults. The disease is characterized by histological evidence of dense esophageal tissue eosinophilia in the presence of a variety of upper GI symptoms including vomiting, dysphagia, food impaction, and odynophagia. Cornerstone of treatment is dietary intervention and/or the off-label use of swallowed topical corticosteroids. New drug therapies are under investigation. In this review, we focus on the diagnostic approach and the currently available treatment strategies.

Abstract
OBJECTIVES Eosinophilic esophagitis (EoE) represents a chronic, immune/antigen-mediated esophageal disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation. With few exceptions, 15 eosinophils per high-power field (peak value) in ≥1 biopsy specimens are considered a minimum threshold for a diagnosis of EoE. The disease is restricted to the esophagus, and other causes of esophageal eosinophilia should be excluded, specifically proton pump inhibitor-responsive esophageal eosinophilia. This position paper aims at providing practical guidelines for the management of children and adolescents with EoE. METHODS Relevant literature from searches of PubMed, CINAHL, and recent guidelines was reviewed. In the absence of an evidence base, recommendations reflect the expert opinion of the authors. Final consensus was obtained during 3 face-to-face meetings of the Gastroenterology Committee and 1 teleconference. RESULTS The cornerstone of treatment is an elimination diet (targeted or empiric elimination diet, amino acid-based formula) and/or swallowed, topical corticosteroids. Systemic corticosteroids are reserved for severe symptoms requiring rapid relief or where other treatments have failed. Esophageal dilatation is an option in children with EoE who have esophageal stenosis unresponsive to drug therapy. Maintenance treatment may be required in case of frequent relapse, although an optimal regimen still needs to be determined. CONCLUSIONS EoE is a chronic, relapsing inflammatory disease with largely unquantified long-term consequences. Investigations and treatment are tailored to the individual and must not create more morbidity for the patient and family than the disease itself. Better maintenance treatment as well as biomarkers for assessing treatment response and predicting long-term complications is urgently needed.

Abstract
The eosinophilic esofagitis is a pathology that consists of an inflammatory condition of the esophagus, which is characterized for having a high percentage of eosinophils. It is a problem of allergic origin and his diagnosis is increasing in the population, especially in children and adult young persons, throughout last decade. The fisiopathology is not completely established nowadays. The diagnosis is confirmed with endoscopia and capture of biopsies. The differential diagnosis is necessary to be done with the disease for reflux gastroesofágico, gastroenteritis eosinofílica, by Crohn's disease, pathology of connective fabric, syndrome hipereosinofílico, infections and response of hypersensitivity to medicaments. Nowadays there is no a treatment that is definitive. We present a clinical case, which was valued initially for the consultation of Primary care.

Abstract
OBJECTIVE To systematically review the literature evaluating the diagnostic accuracy of commonly used diagnostic tests over conventional history taking and physical examination in children ≤ 18 months and >18 months suspected of gastroesophageal reflux disease (GERD). STUDY DESIGN We searched Medline, Embase, and the Cochrane database for studies assessing the diagnostic accuracy of pH-metry, pH-impedance, esophagogastroscopy, barium contrast study, scintigraphy, and empirical treatment as diagnostic tools. Quality was assessed according to Quality Assessment of Studies of Diagnostic Accuracy Included in Systematic Reviews criteria. RESULTS Of the 2178 studies found, 6 studies were included, containing 408 participants (age 1 month-13.6 years) and 145 controls (age 1 month-16.9 years). Studies included children with GERD symptoms; 1 included an atypical presentation. In all the studies, the diagnostic accuracy of pH-metry was investigated, and in 2 studies esophagogastroscopy was investigated as well. Sensitivity and specificity were calculated in 3 studies. The range of reported sensitivity and specificity was broad and unreliable because of poor methodological quality according to Quality Assessment of Studies of Diagnostic Accuracy Included in Systematic Reviews criteria and inadequate study design. CONCLUSION Diagnostic accuracy of tests in children suspected of GERD remains unclear and implications for practice are hard to give. There is an urgent need of well-designed randomized controlled trials where the effect of treatment according to specific signs and symptoms will be compared with the effect of treatment based on the results of additional diagnostic tests, for patient relevant outcomes.

Abstract
AIM We studied eosinophilic esophagitis (EE) to clarify the clinical and endoscopic features of a Japanese case series. METHODS Records of 10 patients diagnosed with EE at our hospital between May 2010 and December 2011 were examined for age, sex, symptoms, allergic disorder, endoscopic findings, and treatment received. Esophageal wall thickness was measured by endoscopic ultrasonography (EUS). RESULTS Patients were seven males and three females with a mean age of 48 years. Symptoms included dysphagia, heartburn, food impaction, and chest pain. Nine patients had a history of allergic diseases. Increased peripheral eosinophil count was observed in one patient whereas increased immunoglobulin E level was observed in eight patients. Endoscopic findings included longitudinal furrows in all patients, mucosal edema in nine patients, loss of vascular pattern in nine patients, white exudates in six patients, cobblestone-like appearance in five patients, and concentric rings in three patients. EUS revealed thickening of the esophageal wall in one patient. Histopathological examination revealed eosinophilic infiltration (≥15 eosinophils/high-powered field) in the esophageal epithelium of all patients. Treatment was required in six patients. Proton pump inhibitor (PPI) therapy was given as the first-line treatment but was ineffective in four patients and effective in two patients. Steroid therapy was given to three patients unresponsive to PPI therapy and was effective. CONCLUSIONS EE was common among relatively young men and was associated with allergic diseases. Longitudinal furrows were observed as the most characteristic endoscopic finding. Esophageal wall thickening was not commonly observed by EUS.

Abstract
Gastroesophageal reflux (GER) is defined as the involuntary retrograde passage of gastric contents into the esophagus with or without regurgitation or vomiting. It is a frequently experienced physiologic condition occurring several times a day, mostly postprandial and causes no symptoms. These infants are also called 'happy spitters'. GER disease (GERD) occurs when reflux of the gastric contents causes symptoms that affect the quality of life or pathologic complications, such as failure to thrive, feeding or sleeping problems, chronic respiratory disorders, esophagitis, hematemesis, apnea, and apparent life-threatening events. About 70-85 % of infants have regurgitation within the first 2 months of life, and this resolves without intervention in 95 % of infants by 1 year of age. The predominant mechanism causing GERD is transient lower esophageal sphincter (LES) relaxation, which is defined as an abrupt decrease in LES pressure to the level of intragastric pressure, unrelated to swallowing and of relatively longer duration than the relaxation triggered by a swallow. Regurgitation and vomiting are the most common symptoms of infant reflux. A thorough history and physical examination with attention to warning signals suggesting other causes is generally sufficient to establish a clinical diagnosis of uncomplicated infant GER. Choking, gagging, coughing with feedings or significant irritability can be warning signs for GERD or other diagnoses. If there is forceful vomiting, laboratory and radiographic investigation (upper gastrointestinal series) are warranted to exclude other causes of vomiting. Irritability coupled with back arching in infants is thought to be a non-verbal equivalent of heartburn in older children. Other causes of irritability, including cow's milk protein allergy, neurologic disorders, constipation and infection, should be ruled out. The presentation of cow's milk protein allergy overlaps with GERD, and both conditions may co-exist in 42-58 % of infants. In these infants, symptoms decrease significantly within 2-4 weeks after elimination of cow's milk protein from the diet. For non-complicated reflux, no intervention is required for most infants. Effective parental reassurance and education regarding regurgitation and lifestyle changes are usually sufficient to manage infant reflux. Sandifer syndrome, apnea and apparent life-threatening events are the extraesophageal manifestations of GERD in infants. Pharmacotherapeutic agents used to treat GERD encompass antisecretory agents, antacids, surface barrier agents and prokinetics. Currently, North American Society for Pediatric Gasroenterology, Hepatology and Nutrition (NASPGHAN) and European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) practice guidelines concluded that there is insufficient evidence to justify the routine use of prokinetic agents. Esomeprazole (Nexium) is now approved in the US for short-term treatment of GERD with erosive esophagitis in infants aged from 1 to 12 months. Although Nissen fundoplication is now well established as a treatment option in selected cases of GERD in children, its role in neonates and young infants is unclear and is only reserved for selective infants who did not respond to medical therapy and have life-threatening complications of GERD.

Abstract
Gastroesophageal reflux disease (GERD) is a growing problem in the pediatric population and recent advances in diagnostics and therapeutics have improved their management, particularly the use of esophago-gastroduodenoscopy (EGD). Most of the current knowledge is derived from studies in adults; however there are distinct features between infant onset and adult onset GERD. Children are not just little adults and attention must be given to the stages of growth and development and how these stages impact the disease management. Although there is a lack of a gold standard test to diagnose GERD in children, EGD with biopsy is essential to assess the type and severity of tissue damage. To date, the role of endoscopy in adults and children has been to assess the extent of esophagitis and detect metaplastic changes complicating GERD; however the current knowledge points another role for the EGD with biopsy that is to rule out other potential causes of esophagitis in patients with GERD symptoms such as eosinophilic esophagitis. This review highlights special considerations about the role of EGD in the management of children with GERD.

Abstract
Objectives. This paper focuses on current diagnostic and treatment options for Eosinophilic Esophagitis (EE). Study Design. literature review. Results. EE can be suspected on history and endoscopy although definitive diagnosis is strictly based on histopathology. It is a relatively new entity and is often misdiagnosed as gastroesophageal reflux (GERD). Eosinophilic infiltration of the esophageal mucosa is responsible for esophageal symptoms which can range from mild to debilitating dysphagia and food impaction, when untreated. In fact recurrent foreign body and food impaction can often be blamed for undiagnosed EE. There seems to be a strong familial component and association with allergy. The introduction of transnasal esophagoscopy in adult laryngology has enabled otolaryngologists to readily diagnose EE and promoted awareness of this often difficult to recognize entity. Conclusions. Despite higher awareness, the literature suggests that EE remains a commonly misdiagnosed condition especially in the otolaryngology community. Genetic studies are required to unfold the true familial and genetic component of this fascinating entity.

Abstract
The otolaryngic allergist must be able to distinguish between common nonallergic diagnoses that present very similarly to allergic conditions. This article describes a few of the vast myriad of conditions that must be ruled out before a diagnosis of allergy may be made. After reading this article clinicians will be able to identify various conditions, which will enhance their ability to appropriately make correct decisions for prompt and efficient management of their patients with allergic or nonallergic diseases of the head and neck.

Abstract
BACKGROUND & AIMS Quantitative microarray analyses have shown increased expression of interleukin-15 (IL-15) messenger RNA in the esophagus of patients with eosinophilic esophagitis (EoE), a recently recognized allergic disorder with poorly understood pathogenesis. METHODS Quantitative polymerase chain reaction and enzyme-linked immunosorbent assay analyses were performed to examine protein and transcript levels in tissue samples from patients with EoE. Tissues from IL-15Ra-deficient and wild-type (control) mice were also examined. Tissue eosinophilia was determined by immunostaining for major basic protein and flow cytometry for cell-surface receptors. RESULTS Quantitative polymerase chain reaction analyses showed that levels of IL-15 and its receptor IL-15Ra were increased approximately 6- and approximately 10-fold, respectively, in tissues from patients with EoE and approximately 3- and approximately 4-fold, respectively, in mice with allergen-induced EoE. A >2-fold increase in serum IL-15 protein levels was also detected in human EoE samples compared with those from healthy individuals. Human IL-15 messenger RNA levels correlated with esophageal eosinophilia (P < .001). IL-15Ra-deficient mice were protected from allergen-induced esophageal eosinophilia compared with controls (P < .001), even though similar levels of airway eosinophilia were observed in all mice. IL-15 activated STAT5 and CD4(+) T cells to produce cytokines that act on eosinophils. Incubation of primary esophageal epithelial cells from mice and humans with IL-15 caused a dose-dependent increase in the mRNA expression and protein levels of eotaxin-1, -2, and -3. CONCLUSIONS IL-15 mediates in the pathogenesis of EoE. IL-15 activates CD4(+) T cells to produce cytokines that act on eosinophils.

Abstract
Eosinophilic esophagitis (EoE) and reflux esophagitis (RE) overlap clinically and histologically. RE is characterized by epithelial infiltration with small numbers of neutrophils and eosinophils, EoE by a prominent eosinophilic infiltrate. Lymphocytic esophagitis (LE), a new entity characterized by peripapillary lymphocytosis, questions the role lymphocytes play in esophageal inflammation. We test the hypothesis that lymphocyte infiltration in RE differs from EoE. One blinded pathologist read esophageal biopsies from 39 RE and 39 EoE patients. Both groups demonstrated significant numbers of lymphocytes (RE 22.7 +/- 2.2/HPF, EoE 19.8 +/- 1.8/HPF). Eosinophils/HPF in RE and EoE were 2.8 +/- 0.7 and 74.9 +/- 8.2, respectively (P < 0.001). Neutrophils were uncommon in RE (0.26 +/- 0.16/HPF) and EoE (0.09 +/- 0.04; P = 0.07). Eight of the 39 RE specimens had >or=50 lymphocytes in >or=1 HPF. Two were consistent with LE. There was an inverse correlation between numbers of eosinophils and lymphocytes in EoE (R = -0.47; P = 0.002), and no correlation between them in RE (R = 0.18; P = 0.36). The patients with EoE who used antireflux medications had fewer lymphocytes (16.3 +/- 1.3 vs 22.2 +/- 2.3/HPF; P = 0.030) and eosinophils (55.6 +/- 5.2 vs 76.0 +/- 8.7/HPF; P = 0.042) than those who did not. The pathological role of lymphocytes in RE and EoE may be underestimated. Our observation that 5% of the RE specimens meet histopathological criteria for LE potentially blurs the line between these entities. The observation that eosinophil counts are lower in EoE when antireflux meds are used supports the notion that reflux plays a role in the clinical expression of EoE.

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
Eosinophilic esophagitis (EoE) is a chronic clinicopathological entity characterized by large numbers of intraepithelial eosinophils infiltrating the esophageal mucosa. The inflammation leads to alterations in the caliber and the motility of the organ, which determines esophageal symptoms, especially dysphagia and frequent food impaction. Firstly described in 1978, EoE represents today an increasingly recognized disease, with cases coming from all developed countries and rising epidemiology. The origin of EoE has been related to allergy to food components or inhalants, and a number of studies support a Th2-type reaction in the origin of the disease. Thus, several treatment strategies based on controlling the exposition to triggering allergens or therapies using anti-allergic drugs have demonstrated efficacy in EoE. Since EoE frequently presents with esophageal stenosis, endoscopic dilation has been also used in treating these patients, but a high risk of complications has been documented. However, single treatment strategies have not been compared to a placebo group in most of studies, and we do not know the long-term consequences of eosinophilic inflammation, esophageal fibrous remodeling or its possible modifications using different therapies. Furthermore, we lack of a common accepted therapeutic end-point to assess the efficacy of the treatment: from mere resolution of symptoms to full control of esophageal inflammation. This article summarizes the current knowledge about the epidemiology, origin and pathogenesis of the disease, and discuses several practical questions, especially those related to how the affected patients should be treated.

Abstract
BACKGROUND Gastroesophageal reflux disease and acid-related conditions (GERD/ARC) are common in pediatric practice but their costs have not been well characterized. AIM To compare healthcare costs (HCC) and healthcare utilization (HCU) of pediatric GERD/ARC between groups of GERD/ARC patients initiated on histamine-2 receptor antagonists (H(2)RAs) or proton pump inhibitors (PPIs) and matched controls. PATIENTS AND METHODS Children (age < 18 years) diagnosed with GERD or ARC (exploratory category) were identified from a large US claims database (1999-2005) using ICD-9 codes. Costs of pediatric GERD/ARC were estimated by comparing 6-month post-diagnosis HCC between cases and matched controls. GERD/ARC-related HCC and HCU for the year 2005 were further compared between GERD/ARC patients initiated with PPIs vs. H(2)RAs in terms of the cost differences relative to pre-initiation (difference-in-difference) and using multivariate regression to adjust for demographics, pre-treatment health status and pre-treatment costs. RESULTS A total of 27 865 matched pairs were identified. GERD/ARC patients incurred on average more 6-month total HCC than controls ($2386). In 2005, 1010 pediatric patients were initiated on H(2)RAs or PPIs. About 61% were initiated on PPIs and incurred 1.8 times higher 6-month post-initiation GERD/ARC-related HCC than H(2)RA-initiated patients ($661 vs. $372, p < 0.001). Although total 6-month GERD/ARC-related HCC increased for both PPI- and H(2)RA-treated patients, the increase was 30% less for PPI-treated patients ($173 vs. $246, p = 0.521) in the difference-in-difference analysis and 69% less in the multivariate analysis ($109 vs. $347, p = 0.040). LIMITATIONS The use of an exploratory definition for GERD/ARC, administrative claims data and potential coding errors in diagnosis codes used in selection process may limit the generalizability of the results. CONCLUSION Pediatric GERD/ARC patients incurred significantly higher healthcare costs compared to similar children without GERD/ARC. Compared to patients initiated with H(2)RAs, patients initiated with PPIs had more baseline comorbidities, and lower GERD/ARC-related HCC after beginning treatment.

Abstract
Eosinophilic esophagitis (EoE) is a newly recognized disease and is an emerging entity throughout developing and developed countries, including the United States. Therefore, understanding the causes, natural history, diagnosis, and management is important for future therapeutic interventions. The pathogenesis of EoE is still not clear, but a growing body of evidence has established that this condition represents a T-cell-mediated immune response involving several proinflammatory mediators and chemoattractants known to regulate eosinophilic accumulation in the esophagus, such as IL-4, IL-5, IL-3 and eotaxin-1, -2, and -3. Determining the mechanism or mechanisms through which human esophageal-derived factors ultimately induce the functional abnormalities observed, and to which antigens patients who have EoE are sensitized that lead to the manifestation of symptoms, is of significant interest.

Abstract
OBJECTIVE To develop a North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) international consensus on the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. METHODS An international panel of 9 pediatric gastroenterologists and 2 epidemiologists were selected by both societies, which developed these guidelines based on the Delphi principle. Statements were based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. The committee convened in face-to-face meetings 3 times. Consensus was achieved for all recommendations through nominal group technique, a structured, quantitative method. Articles were evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence. Using the Oxford Grades of Recommendation, the quality of evidence of each of the recommendations made by the committee was determined and is summarized in appendices. RESULTS More than 600 articles were reviewed for this work. The document provides evidence-based guidelines for the diagnosis and management of gastroesophageal reflux and gastroesophageal reflux disease in the pediatric population. CONCLUSIONS This document is intended to be used in daily practice for the development of future clinical practice guidelines and as a basis for clinical trials.

Abstract
The practice of pediatric gastrointestinal pathology provides specific challenges to the pathologist. Often the clinical information accompanying a biopsy specimen will read simply, "failure to thrive." Other situations, such as the evaluation of a neonate's rectal suction biopsy for Hirschsprung disease, are notorious for providing diagnostic challenges in high-pressure situations. In this review, we will discuss several commonly encountered situations in pediatric pathology: the evaluation of pediatric esophageal eosinophilia, a child who has swallowed a non food item, caustic substance, or hot liquid, the evaluation of a pediatric colorectal biopsy with focal active colitis, and the evaluation of rectal suction biopsies for Hirschsprung disease. With each topic, we will discuss a general approach to the case, diagnostic tips, and how to avoid commonly encountered pitfalls. Finally, we highlight key references pertinent to these issues that can he used to help convey pathologic findings to pediatric gastroenterologists.

Abstract
OBJECTIVES To develop an international consensus on the definition of gastroesophageal reflux disease (GERD) in the pediatric population. METHODS Using the Delphi process, a set of statements was developed and voted on by an international panel of eight pediatric gastroenterologists. Statements were based on systematic literature searches using Medline, EMBASE, and CINAHL. Voting was conducted using a six-point scale, with consensus defined, a priori, as agreed by 75% of the group. The strength of each statement was assessed using the GRADE system. RESULTS There were four rounds of voting. In the final vote, consensus was reached on 98% of the 59 statements. In this vote, 95% of the statements were accepted by seven of eight voters. Consensus items of particular note were: (i) GERD is present when reflux of gastric contents causes troublesome symptoms and/or complications, but this definition is complicated by unreliable reporting of symptoms in children under the age of approximately 8 years; (ii) histology has limited use in establishing or excluding a diagnosis of GERD; its primary role is to exclude other conditions; (iii) Barrett's esophagus should be defined as esophageal metaplasia that is intestinal metaplasia positive or negative; and (iv) extraesophageal conditions may be associated with GERD, but for most of these conditions causality remains to be established. CONCLUSIONS The consensus statements that comprise the Definition of GERD in the Pediatric Population were developed through a rigorous process. These statements are intended to be used for the development of future clinical practice guidelines and as a basis for clinical trials.

Abstract
BACKGROUND Eosinophilic oesophagitis (EO) is a chronic inflammatory disease of the oesophagus, with an emergent character, defined by the presence of a dense infiltrate by eosinophilic leukocytes restricted to the mucosa of this organ after excluding gastro-oesophageal acid reflux. It is manifested by chronic and/or recurrent dysphagia and episodes of oesophageal alimentary impaction, with great variation in terms of intensity, frequency, and duration of the attacks. METHODS An Internet-based search was performed for the most recent articles with relevant information concerning immunopathological mechanisms involved in EO. RESULTS Bibliographical data allow us to define that EO is related to an allergic or hypersensitivity-induced reaction after exposure to foods or inhalants, with increased prevalence of sensitisation to these allergens. Data published up to now suggest a cellular hypersensitivity reaction rather than a humoral one in the physiopathology of EO. In this disease, sensitised T-lymphocytes mediate a Th2 type response, releasing cytokines such as IL-5, with a possible Th1 component that requires further investigation. The function of the abundant CD8+ T-lymphocytes present in the oesophageal epithelium has yet to be explained. Mast cells also participate in epithelial inflammatory infiltrate in EO, and it is still unknown if its activation, mainly through IgE, contributes to the immunopathology of the disease even though EO rarely manifests immediate hypersensitivity reactions. IL-5 and different forms of eotaxins perform an important active role in the recruitment of eosinophils to the oesophagus. CONCLUSIONS EO is an immunologically complex and little studied entity that is associated with other allergic diseases and in which different effector cells participate, determining an immunological response of cellular rather than a humoral hypersensitivity reaction. The data available point out that EO is a disorder of the Th2 retarded immune response, in which the triggering factor might not be IgE. Although the final inflammatory phenomena observed in EO are common for the different patients, the cascade of inflammatory mediators that lead to them might not be identical in all cases, and the morphological and functional disorders observed in EO would represent the final convergence of different activation forms of the mechanisms of inflammation.

Abstract
Eosinophilic esophagitis (EOE) is a clinical pathologic syndrome characterized by influx of numerous eosinophils into the esophageal epithelium. It is important for clinicians to be aware of the spectrum, as well as the characteristic location and distribution, of morphologic changes in EOE to maximize the diagnostic yield in mucosal biopsy specimens. The major pathologic features of EOE include eosinophilic microabscesses, surface layering of eosinophils often associated with surface sloughing of necrotic squamous cells, and peak eosinophil counts usually greater than 15 per high power field (hpf) within the squamous epithelium. Minor features, which are frequent but less specific, include marked basal cell hyperplasia, lengthening of lamina propria papillae, intercellular edema, and lamina propria fibrosis with chronic inflammation. The number, distribution, and location of intraepithelial eosinophils in EOE vary greatly between previously published studies. Thus, utilization of a diagnostic cutoff point for intraepithelial eosinophils in EOE, particularly in the absence of other major features of EOE, is currently considered unwise. In fact, some patients may show combined features of both gastroesophageal reflux disease (GERD) and EOE, which complicates the histologic analysis of these patients. In contrast to GERD, EOE typically involves longer lengths of the esophagus, affects the proximal equally, or even more, than the distal esophagus, and the pathologic findings are often patchy in distribution. As a result, it is highly recommended that clinicians obtain biopsies from patients suspected of have EOE only after treatment with high-dose proton pump inhibitor therapy, and that biopsies be obtained from both the proximal and distal esophagus in both normal and abnormal appearing areas.

Abstract
Hyperplastic esophagogastric polyps usually occur in the distal esophagus or gastroesophageal junction and have been associated with damage to the esophageal mucosa. Histologically these polyps show hyperplastic gastric foveolar and/or squamous epithelium with inflamed stroma. Reports of esophagogastric polyps in the pediatric population are rare. Most of these reports only describe chronic inflammation within the lamina propria of the polyp, with only rare reports specifying the presence of epithelial hyperplasia. There have been 2 previous cases of hyperplastic esophagogastric polyps occurring in the context of neurofibromatosis type 1 (NF-1) in a single article. Here we report a 3rd case of hyperplastic esophagogastric polyps occurring in an 11-year-old male with NF-1. This case is unique in that there were 2 polyps in the same patient and in that the polyps showed hyperplastic gastric peptic glands in addition to foveolar-type and focal squamous epithelium. The case is discussed and literature reviewed.

Abstract
PURPOSE Children with intestinal failure (IF) often have gastrointestinal (GI) symptoms, including bleeding, increased stool output, and feeding intolerance. The use of endoscopic assessment of these symptoms has not been previously reported. This report evaluates the diagnostic yield of GI endoscopy in the setting of IF. METHODS After institutional review board approval, we reviewed the medical records (including endoscopy, pathology and microbiology data) of patients with IF who underwent GI endoscopies between September 1999 and March 2007. RESULTS Twenty-seven patients underwent 61 GI endoscopies: 34 esophagogastroduodenoscopies, 17 colonoscopies, 7 flexible sigmoidoscopies, and 3 ileoscopies. Indications for endoscopy, which were not mutually exclusive, included chronic diarrhea (39%, n = 24), GI bleeding (36%, n = 22), suspected bacterial overgrowth (36%, n = 22), and suspected peptic disease (15%, n = 9). Based on gross endoscopic appearance, histopathology, or microbiology, 43 (70%) procedures yielded abnormalities. These included infectious (20%, n = 12), anatomical (18%, n = 11), peptic (15%, n = 9), allergic (15%, n = 9), and other (2%, n = 1) findings. Eleven (73%) of 15 duodenal cultures grew a spectrum of 17 bacterial species. Overall, 24 (89%) of 27 patients had gross endoscopic, histopathologic, or microbiologic abnormalities. CONCLUSIONS In pediatric patients with IF, diagnostic upper and lower GI endoscopies yield high rates of abnormalities and can help guide clinical management.

Abstract
Eosinophilic esophagitis represents the most debated disease of the last 10 years, too often speculated or overestimated and certainly well known and examined. The aim of this study was to summarize the recent therapeutic trends in order to show persistent doubts regarding several debated therapies. The study combined the most recent international literature and the authors' daily experience to define the scope of the review, with limits caused by a lack of available randomized studies between dietetic and pharmacological treatment. It was concluded that eosinophilic esophagitis is an immunoallergic disease that is generally caused by identifiable food and environmental allergens although, in a minority of cases, the etiological trigger remains undetermined. Therapy usually fights the responsible agents, but sometimes they are not resolved. A need for more pathogenetically driven treatments is invoked.

Abstract
BACKGROUND & AIMS Eosinophilic esophagitis (EE) is an increasingly recognized disease that mimics gastroesophageal reflux disease. Recently, EE has been associated with esophageal remodeling, but the mechanisms involved are poorly understood. We hypothesized that the development of EE in patients and in an experimental murine model would be associated with eosinophil-mediated tissue remodeling. METHODS Histopathologic analysis of basal layer thickness and collagen accumulation was performed on the biopsy specimens of normal individuals, EE patients, and mouse esophageal tissue sections following experimental induction of EE in wild-type, eosinophil lineage-deficient, interleukin (IL)-5-deficient, and IL-5 transgenic mice, with the latter 2 mice groups having decreased and increased esophageal eosinophilia, respectively. RESULTS An impressive accumulation of collagen in the epithelial mucosa and lamina propria, as well as basal layer thickening, was observed in the esophagus of patients with EE as well as in mice with experimental EE compared with controls. Significantly reduced lamina propria collagen and basal layer thickness were observed in IL-5-deficient mice and eosinophil lineage-deficient mice compared with wild-type mice following the induction of experimental EE. Furthermore, the esophagus of CD2-IL-5 transgenic mice showed increased basal layer thickness and collagen accumulation compared with nontransgenic mice, yet IL-5 intestine transgenic mice did not have EE-like esophageal changes. Additional analysis revealed increased IL-5 levels in the esophagus of EE patients, allergen-challenged wild-type mice, and CD2-IL-5 transgenic mice but not in IL-5 intestine transgenic mice. CONCLUSIONS These findings provide evidence that local IL-5-mediated eosinophilia is essential in the induction of esophageal remodeling.

Abstract
Over the last decade, treatment plans for eosinophilic esophagitis included the use of elemental formula, elimination diets, systemic corticosteroids, and the gavage of aerosolized steroids. Except for one placebo-controlled blinded prospective study, most decision making has been based on retrospective or uncontrolled studies and clinical experience. In this article, three authors from diverse backgrounds combine their resources to propose treatment paths with justification based on their clinical experience and interpretation of the literature.

Abstract
Eosinophilic gastroenteritis is a rare benign disease characterized by tissue eosinophilic infiltration that may involve several digestive tract layers. Also known as allergic, or eosinophilic allergic, gastroenteropathy, it usually involves the stomach and small intestine: rarely the colon. It may or may not be accompanied by higher counts of eosinophils in the peripheral blood. The main clinical manifestations depend on the site affected. It has been classified according to clinical and pathological features, and the symptoms depend on the patient's immunological response to several cytokines released by eosinophils. Because of lack of understanding of the etiology and triggering factors, treatment is based mainly on corticosteroids; although other drugs acting on the immune system have been tested, the results are not always satisfactory. This review focuses on the epidemiology, pathophysiology, clinical features, and treatment of this hitherto under-diagnosed disease.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is an emerging clinicopathologic entity defined by abnormal esophageal eosinophilic infiltration. Our understanding of this disease is hampered by the lack of a uniform diagnostic standard. The aim of this systematic review was to determine the range of diagnostic strategies and histologic criteria in the EoE literature. METHODS The MEDLINE-indexed literature from 1950 through December 31, 2006 was independently searched by two investigators. To identify additional relevant studies, bibliographies were hand searched, as were the published proceedings of the 2000-2006 American College of Gastroenterology and American Gastroenterological Association national meetings. Data were extracted from all human EoE case reports, case series, cross-sectional and cohort studies, and clinical trials. RESULTS Of 318 publications initially identified, 116 original articles, 39 abstracts, and 69 reviews were included. We found 10 different histologic definitions of EoE, ranging from 5 to 30 eosinophils per high-powered field (hpf), though 41 (35%) of the original articles did not state their diagnostic criteria. In the 13 original articles (11%) reporting an hpf area, the eosinophil density per mm(2) varied 23-fold. There was also variation in esophageal biopsy protocols, but specific protocols were reported in just 45 (39%) original articles. CONCLUSIONS Significant variability in diagnostic criteria for eosinophilic esophagitis exists, and in a large proportion of studies, criteria are not reported. Because of this lack of a common disease definition, conclusions drawn from the cumulative EoE literature should be viewed with caution. A consensus research-quality standard for diagnosis of eosinophilic esophagitis is needed.

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
Recent data suggest that the interaction between gastroesophageal reflux disease (GERD) and eosinophilic esophagitis can be complex, and that the notion of establishing a clear distinction between the two disorders may be too simplistic. There are at least four situations in which GERD might be associated with esophageal eosinophils: (a) GERD causes esophageal injury that results in a mild eosinophilic infiltration, (b) GERD and eosinophilic esophagitis coexist but are unrelated, (c) eosinophilic esophagitis contributes to or causes GERD, or (d) GERD contributes to or causes eosinophilic esophagitis. The high frequency of GERD described in adult patients with eosinophilic esophagitis suggests that there may be more than a chance association between the two disorders. This report discusses potential mechanisms for the complex interaction between GERD and eosinophilic esophagitis. We hope that this information will serve as a conceptual basis for future studies on the relationship between the two disorders. Whereas there are a number of plausible mechanisms whereby GERD might contribute to the accumulation of eosinophils in the esophageal epithelium, it seems prudent to recommend a clinical trial of proton pump inhibitor (PPI) therapy even when the diagnosis of eosinophilic esophagitis seems clear-cut. Furthermore, we suggest that a favorable response to PPI therapy does not preclude a diagnosis of eosinophilic esophagitis.

Abstract
Eosinophilc esophagitis (EE) is an emerging disease which is characterized by a dense infiltration of the esophagus by eosinophilic leukocytes. The main symptoms of this disease are dysphagia and frequent food impaction in esophagus, and they are due to a hypersentivity response to different foods or aeroallergens. Eosinophil accumulation in the esophageal epithelium is determined by local production of eosinophilotropic cytokines and chemokines, which have been well defined as a TH2-type hypersensitivity reaction in animal models of the disease. Esophageal epithelium, after T CD4+ lymphocytes stimulation, contains all the necessary cell types for the development of local immunoallergic responses. However, there is increasing data on the significant role that humoral immunity could play in the pathophysiology of EE, by means of the action of IgE over mast cells function. The high density of T CD8+ lymphocytes in inflammatory infiltrate suggests that a TH1-type reaction could also participate in the mechanism of the disease. Proteins contained in cytoplasmic granules of activated eosinophils and mast cells could act over neural and muscular components of the esophageal wall, triggering motor disturbances which can be measured by means of manometric recordings and justify the esophageal symptoms. This paper aims to review the newest clinical aspects of EE and the results of studies directed at investigating the pathophysiology of the disease. Furthermore, we carry out a critical review of available therapeutic options.

Abstract
BACKGROUND We performed a systematic review to examine the diagnostic yield (endoscopic and histologic) of esophagogastroduodenoscopy (EGD) for the evaluation of abdominal pain of unclear etiology in children. We also examined the effect of EGD on change in treatment, quality of life, change in abdominal pain, and cost-effectiveness. METHODS All full-length articles published in English during 1966-2005 were included if: (a) participants had abdominal pain without known underlying gastrointestinal disease, (b) participants underwent EGD primarily for the evaluation of abdominal pain, (c) findings of the EGD were reported, (d) participants were under 18 yr, and (e) sample size greater than 50. RESULTS Eighteen articles examining 1,871 patients fulfilled the inclusion and exclusion criteria. All were observational and most (13) were prospective. Only three studies were performed in the United States and of those two were prospective. The largest study examined about 400 procedures and 13 studies examined less than 100 procedures. One case of inflammatory bowel disease and 67 duodenal or gastric ulcers were reported, thus diagnostic yield was achieved in 3.6% of cases. The prevalence of nonspecific histological gastrointestinal inflammatory lesions varied between 23% and 93%. Six articles attempted to correlate endoscopic or histologic findings with treatment management decisions. No articles attempted to describe quality of life or cost-effectiveness. None of the studies analyzed the association of alarm symptoms or signs to diagnostic yield. CONCLUSIONS The diagnostic yield of EGD in children with unclear abdominal pain is low; however, existing studies are inadequate. The effect of EGD on change in treatment, quality of life, improvement of abdominal pain, and cost-effectiveness is unknown. The predictors of significant findings are unclear. Our findings suggest that a large multicenter study examining clinical factors, biopsy reports, and addressing patient outcomes is needed to further clarify the value of EGD in children with abdominal pain.

Abstract
Although we know that eosinophils reside in the normal gastrointestinal tract and increase during inflammatory states, their exact role in gut homeostasis and in the pathogenesis of inflammatory processes is not certain. An increasing number of clinical reports suggest that eosinophils participate in the pathogenesis of mucosal inflammation, and emerging literature is beginning to define these mechanisms. For example, homing of eosinophils to the gastrointestinal tract is better understood with respect to the roles of specific eosinophilic attractants, such as the eotaxins and interleukin-5. As mechanisms of eosinophil recruitment, activation, and functional responses are further elucidated, novel targets for treatment strategies in specific diseases will likely follow. We review recent developments in eosinophil immunobiology as they relate to gastrointestinal inflammation and provide an update on clinical aspects of eosinophilic esophagitis as they relate to eosoinophilic diseases of the gastrointestinal tract.

Abstract
OBJECTIVES We sought to determine the reliability of morphometric measurements on infant esophageal biopsies using a light microscope with eyepiece micrometer. METHODS We measured epithelial thickness, basal layer thickness (B), papillary height (P) and epithelial lymphocyte and eosinophil numbers on approximately 500 existing esophageal suction biopsies from infants previously evaluated for reflux esophagitis. We tested these measurements for interobserver, test-retest and internal consistency reliability. RESULTS Infants ages 0.25 to 23.75 (median, 6.25) months provided 497 biopsies. Both investigators scoring the biopsies independently judged 93% of them scorable. Of the biopsies scored by both, the 2 readings were within 0.15 of each other for P in 97% and for B in 81%. In addition to these correlative measures of consistency, categoric measures demonstrated that 373 (89%) of the 420 scorable biopsies with visible papillae produced agreement as to P being abnormal (317, 85%) or normal (56, 15%). Similarly, 360 (78%) of the 463 scorable biopsies produced agreement as to B being abnormal (339, 94%) or normal (21, 6%). P values were 0.17 to 0.94 (median, 0.67), and B values were 0.13 to 0.91 (median, 0.34). Lymphocytes numbered 0 to 40 (median 5) per high-power field. Only 12% had any eosinophils; none of those with completely normal morphometrics had any eosinophils; and only 2% had >5 eosinophils per high-power field. CONCLUSIONS Simple quantitative esophageal histological morphometric parameters are reliably measurable on suction biopsies from infants using a light microscope fitted with an ocular micrometer, even by nonpathologists.

Abstract
OBJECTIVES To evaluate the utility of activated mucosal mast cells (MC) in the differential diagnosis of eosinophilic esophagitis (EE) and gastroesophageal reflux disease (GERD). METHODS Intraepithelial eosinophils and MC were quantified in esophageal biopsies from 25 children with EE, 22 children with GERD and 22 controls. MCs were identified by immunohistochemistry for MC tryptase, whereas MC activation status was evaluated by immunohistochemistry for immunoglobulin E (IgE) and by electron microscopy. RESULTS Esophageal biopsies from patients with EE showed higher intraepithelial eosinophil counts (55 +/- 27.5 vs 6.9 +/- 9.7, P < 0.0001) and MC counts (26.3 +/- 12.7 vs 7.8 +/- 8.9, P < 0.0001) than those from patients with GERD. Almost all EE biopsies (24 of 25 patients; 96%) contained IgE-bearing cells compared with 9 of 22 (41%) GERD biopsies (P < 0.001). GERD biopsies with intraepithelial eosinophil counts >7/high-power field (suggesting an allergic component) contained IgE-bearing cells in 6 of 7 (86%) cases compared to 3 of 15 (20%) cases with eosinophil counts <7/h.p.f (P < 0.01). No intraepithelial eosinophils, MC or IgE-positive cells were present in controls. Electron microscopy confirmed the presence of intraepithelial MC and changes in cytoplasmic granules indicative of MC and eosinophil activation. CONCLUSIONS Intraepithelial MC counts and IgE-bearing cells may help to differentiate EE and GERD and to define a subset of GERD patients in which an allergic component is present. The findings support a role for a MC-mediated hypersensitivity reaction in the pathogenesis of EE.

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.
