Seguridad de la endoscopia y biopsia esofágica en un paciente con esofagitis eosinofílica y enfermedad de Von Willebrand / Safety of esophageal endoscopy and biopsy in a patient with eosinophilic esophagitis and Von Willebrand disease

La esofagitis eosinofílica (EoE) es una enfermedad causada por una respuesta inmune frente a antígenos alimentarios en contacto con la mucosa esofágica; por su parte, la enfermedad de Von Willebrand (EVW) es el trastorno hemorrágico hereditario más común en los seres humanos. La característica central de todos los tipos de EVW, es la presencia de cantidades reducidas o de formas anormales del factor de Von Willebrand (FVW) en el torrente sanguíneo. Debido a que no se han reportado casos previos de EVW tipo 2A asociada a EoE, se describe este caso clínico con el objetivo principal de dar a conocer el hallazgo casual de estas dos patologías, la seguridad de la evaluación por endoscopia de vías digestivas altas y el pronóstico de posibles complicaciones

Eosinophilic esophagitis (EoE) is a disease caused by an immune response against food antigens in contact with the esophageal mucosa; alternatively, Von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. The central characteristic of all types of VWD is the presence of reduced amounts or abnormal forms of VWF in the bloodstream. Since no previous cases of VWD type 2A associated to EoE have been reported, this clinical case is described with the main objective to present the coincidental finding of these two pathologies, the safety of the evaluation by upper gastrointestinal endoscopy, and the prognosis of possible complications

Association between endoscopic findings and histopathological confirmation in patients with suspicion of eosinophilic esophagitis / Associação entre achados endoscópicos e confirmação histopatológica em pacientes com suspeita de esofagite eosinofílica

ABSTRACT BACKGROUND: The diagnosis of eosinophilic esophagitis (EoE) is performed by the detection of 15 or more eosinophils per field in an esophageal biopsy sample, but the endoscopic findings alone are not validated for a diagnosis of the disease. OBJECTIVE: To evaluate the association between the endoscopic findings and histopathological diagnosis in patients with suspected EoE in endoscopy. METHODS: A retrospective study of 24 patients with suspicion of EoE during endoscopy was held. The information was collected from databases of Endoscopy and Pathology services of the Hospital Universitário Walter Cantídio, Universidade Federal do Ceará, from March 2012 to April 2018. The patients were divided into a group with positive biopsy (>15 Eosinophils/field, N=8) and a group with negative biopsy (<15 Eosinophils/field, N=16), and the endoscopic findings were compared between the two groups. RESULTS: From a total of 24 patients, 79.1% had longitudinal grooves, 20.8% white exudates, 33.3% mucosal pallor or loss of vascularity and 45.8% had more than one endoscopic finding. There was a significant difference (P<0.05) in the evaluation of the finding of mucosal pallor or decreased vasculature alone among the groups. The positive predictive value and negative predictive value of the presence of more than one endoscopic findings for the diagnosis of EoE was 54% and 84%, respectively. CONCLUSION: There was a low association between the presence of endoscopic findings and histopathological confirmation of the disease, which indicates that endoscopic findings alone are not reliable for the diagnosis of EoE.

RESUMO CONTEXTO: O diagnóstico da esofagite eosinofílica é realizado através da detecção, em amostra de biópsia esofágica, de 15 ou mais eosinófilos por campo, sendo que os achados endoscópicos isolados não são validados para o diagnóstico da doença. OBJETIVO: Avaliar a associação entre os achados endoscópicos com o diagnóstico histopatológico em pacientes com suspeita de esofagite eosinofílica na endoscopia. MÉTODOS: Estudo retrospectivo de 24 pacientes com suspeita de esofagite eosinofílica durante endoscopia digestiva alta. As informações foram colhidas de bancos de dados dos serviços de Endoscopia e Patologia do Hospital Universitário Walter Cantídio da Universidade Federal do Ceará, no período de março de 2012 a abril de 2018. Os pacientes foram divididos em grupo com biópsia positiva (>15 eosinófilos/campo, N=8) e grupo com biópsia negativa (<15 eosinófilos/campo, N=16), sendo comparados os achados endoscópicos entre os dois grupos. RESULTADOS: Do total de 24 pacientes, 79,1% tinham a presença de sulcos longitudinais, 20,8% exsudatos brancos, 33,3% palidez de mucosa ou perda da vascularização e 45,8% apresentaram mais de um achado endoscópico. Houve diferença significativa (P<0,05) na avaliação do achado de palidez ou perda da vascularização, isoladamente, entre os grupos. O valor preditivo positivo e valor preditivo negativo da presença de mais de um achado endoscópico para o diagnóstico de esofagite eosinofílica foi de 54% e 84%, respectivamente. CONCLUSÃO: Houve uma baixa associação entre a presença de achados endoscópicos e a confirmação histopatológica da doença, o que faz com que os achados endoscópicos isolados não sejam confiáveis para o diagnóstico de esofagite eosinofílica.

Caracterização histopatológica da esofagite eosinofílica em crianças e adolescentes / Histological features of eosinophilic esophagitis in children and adolescents

ABSTRACT BACKGROUND: Eosinophilic esophagitis is an emerging disease featured by eosinophilic esophageal infiltrate not responsive to proton pump inhibitors. OBJECTIVE: To characterize histological features of children and adolescents with eosinophilic esophagitis. METHODS: Cross-sectional study in a tertiary hospital. Biopsies from each esophageal third from 14 patients (median age 7 years) with eosinophilic esophagitis were evaluated. Histological features evaluated included morphometry of esophageal epithelium, esophageal density (per high power field), extracellular eosinophilic granules, eosinophilic microabscesses, surface disposition of eosinophils, epithelial desquamation, peripapillary eosinophilia, basal layer hyperplasia and papillary elongation. RESULTS: Several patients presented a normal esophageal macroscopy in the upper digestive endoscopy (6, 42.8%), and the most common abnormality were vertical lines (7, 50%) and whitish spots over esophageal mucosa (7, 50%). Basal layer hyperplasia was observed in 88.8%, 100% e 80% of biopsies from proximal, middle and lower esophagus, respectively (P=0.22). Esophageal density ranges from 0 to more than 50 per hpf. Extracellular eosinophilic granules (70%-100%), surface disposition of eosinophils (60%-93%), epithelial desquamation (60%-100%), peripapillary eosinophilia (70%-80%) were common, but evenly distributed among each esophageal third. Just one patient did not present eosinophils in the lower third, four in the middle third and four in the upper esophageal third. CONCLUSION: In the absence of hypereosinophilia, other histological features are present in eosinophilic esophagitis and may contribute to diagnosis. Eosinophilic infiltrate is focal, therefore multiple biopsies are needed for diagnosis.

RESUMO CONTEXTO: Esofagite eosinofílica é uma doença emergente caracterizada por infiltrado eosinofílico esofágico não responsivo a inibidores de bomba de prótons. OBJETIVO: Caracterizar os achados histopatológicos de uma coorte de crianças e adolescentes com diagnóstico de esofagite eosinofílica. MÉTODOS: Estudo transversal conduzido em hospital terciário. Biópsias de terços proximal, médio e distal de 14 pacientes (idade mediana 7 anos) com diagnóstico de esofagite eosinofílica. Estudo morfométrico e variáveis histológicas analisadas em fragmentos de biópsias nos terços esofágicos: contagem de eosinófilos/CGA, grânulos eosinofílicos extracelulares, microabscessos eosinofílicos, disposição superficial de eosinófilos, descamação epitelial, eosinofilia peripapilar, hiperplasia da camada basal e alongamento de papilas. RESULTADOS: Vários pacientes apresentaram aspecto macroscópico normal da mucosa esofágica à endoscopia (6, 42.8%), e a anormalidade mais comumente observada foi linhas verticais (7, 50%) e exsudato branco (7, 50%). Hiperplasia da camada basal foi observada em 88,8%, 100% e 80% das biópsias do terço proximal, médio e distal respectivamente (P=0,22); contagem de eosinófilos nos terços variou de 0 a ≥50/CGA, grânulos eosinofílicos extracelulares (70%-100%), disposição superficial de eosinófilos (60%-93%), descamação epitelial (60%-100%), eosinofilia peripapilar (70%-80%), sem diferença estatística entre os terços esofágicos. Ausência de eosinofilia ocorreu raramente em terço distal (uma do distal, quatro do proximal, quatro do médio). CONCLUSÃO: Na ausência de hipereosinofilia, outros achados histopatológicos de inflamação eosinofílica estão presentes. A infiltração eosinofílica apresentou caráter focal, sugerindo-se a realização de múltiplas biópsias de diversos segmentos.

Mastócitos discriminam esofagite eosinofílica em pacientes pediátricos / Mast cells distinguish eosinophilic esophagitis in pediatric patients

ABSTRACT BACKGROUND: Mast cells exert a substantial role in gastrointestinal allergic diseases. Therefore, it is reasonable to presume that mast cell may aid diagnosis in eosinophilic gastroenteropathy. OBJECTIVE: To evaluate whether mast cell count in the esophageal epithelium can discriminate eosinophilic esophagitis, proton-pump inhibitor (PPI)-responsive eosinophilic esophagitis and gastroesophageal reflux esophagitis. METHODS: Retrospectively we reviewed the files of 53 consecutive patients (age: 7.8 years; range: 8-14 years) with definitive diagnose established during clinical follow up in a universitary outpatient clinic as follow: eosinophilic esophagitis (N=23), PPI-responsive eosinophilic esophagitis (N=15) and gastroesophageal reflux esophagitis (N=15). Eosinophil count in the esophageal epithelium in slides stained with H-E was reviewed and immunohistochemistry for mast cell tryptase was performed. RESULTS: Count of eosinophils/high-power field (HPF) higher than 15 were found in 14 out of 15 reflux esophagitis patients. The mean count of eosinophils/HPF was similar in eosinophilic esophagitis patients and in those with PPI-responsive eosinophilic esophagitis (42 and 39 eosinophils/HPF, respectively, P=0.47). Values of mast cell tryptase (+) were higher in eosinophilic esophagitis [median: 25 mast cells/HPF; range (17-43) ] and in PPI-responsive eosinophilic esophagitis patients [25 (16-32) ], compared to reflux esophagitis [4 (2-14) ], P<0.001. There was no difference between the mean count of mast cells/HPF in the esophageal epithelium of eosinophilic esophagitis patients and PPI-responsive eosinophilic esophagitis patients, respectively, 26 and 24 mast cells/HPF, P=0.391. CONCLUSION: Tryptase staining of mast cells differentiates eosinophilic esophagitis from reflux esophagitis.

RESUMO CONTEXTO: Os mastócitos detêm papel fundamental na resposta imuno-alérgica gastrintestinal. Assim, é razoável admitir que essas células sejam úteis no diagnóstico diferencial das gastroenteropatias eosinofílicas. OBJETIVO: Determinar se a análise quantitativa de mastócitos na mucosa esofágica permite discernir esofagite eosinofílica, esofagite eosinofílica responsiva ao inibidor de bomba de prótons e esofagite péptica por doença de refluxo gastroesofágico. MÉTODOS: Revisamos retrospectivamente os prontuários 53 crianças (idade: 7,8 anos; variação: 8-14 anos), atendidas consecutivamente, num serviço terciário e cujos diagnósticos definitivos estabelecidos após seguimento clínico foram esofagite eosinofílica (N=23), esofagite eosinofílica responsiva ao inibidor de bomba de prótons (N=15) e esofagite péptica por doença de refluxo gastroesofágico (N=15). As amostras histológicas foram revisadas quanto à contagem de eosinófilos na coloração de H-E e processadas para imunoistoquímica da triptase de mastócitos. RESULTADOS: Valores de eosinófilos/campo de maior aumento (CMA; 400X) >15 foram encontrados em 14 dos 15 pacientes com refluxo gastroesofágico. A média de eosinófilos/CMA foi similar nos pacientes com esofagite eosinofílica e com esofagite eosinofílica responsiva ao inibidor de bomba de prótons, respectivamente, 42 e 39 eosinófilos/CMA, P=0,47). Os valores de mastócitos triptase (+) foram superiores no epitélio esofágico dos pacientes com esofagite eosinofílica [mediana: 25 mastócitos/CMA; variação (17- 43) ] e na esofagite eosinofílica responsiva ao inibidor de bomba de prótons [25 (16-32) ], comparados aos pacientes com refluxo gastroesofágico [4(2-14) ], P<0,001. Não houve diferença entre a média de mastócitos/CMA nos pacientes com esofagite eosinofílica comparados aos com esofagite eosinofílica responsiva ao inibidor de bomba de prótons, respectivamente, 26 e 24 mastócitos/CMA, P=0,391. CONCLUSÃO: A coloração para mastócitos pela imunoistoquímica da triptase diferencia as esofagites eosinofílicas da esofagite péptica.

Manifestações clínicas, terapêutica e evolução de crianças e adolescentes com esofagite eosinofílica / Clinical manifestations, treatment, and outcomes of children and adolescents with eosinophilic esophagitis

OBJECTIVE: This study aimed to describe the clinical, endoscopic, and histologic characteristics, as well as the response to conventional treatment of pediatric patients with the classical form of eosinophilic esophagitis (EoE). METHODS: Study of clinical, laboratory, endoscopic, and histologic data and response to conventional treatment of 43 previously followed pediatric patients with the classical form of EoE. RESULTS: A total of 43 patients diagnosed with EoE were included in the study, of which 37 were males (86%), with a mean age of 8.4 years. The most common symptoms were: nausea, vomiting, and abdominal pain (100%) in children younger than 7 years, and loss of appetite (60%), heartburn (52%), and food impaction (48%) in children older than 7 years and adolescents. Regarding the endoscopic findings, 12 (28%) patients had whitish plaques on the esophageal lining, 8 (18.5%) had longitudinal grooves, 2 (4.5%) had concentric rings, 3 (7%) had longitudinal grooves and whitish plaques, and the remaining 18 (42%) had esophageal mucosa with normal appearance. Despite the initial favorable response, 76.7% of patients required more than one course of corticosteroid therapy (systemic or aerosol) and diet (exclusion or elimination of food or elementary allergens). Persistence of eosinophil infiltration was found in some patients despite favorable clinical response. CONCLUSIONS: The classic form of EoE typically shows different symptoms according age range. A significant number of patients required more than one treatment cycle to show clinical remission. Endoscopic and histologic improvement was observed; however, eosinophilic infiltration persisted in some patients.

OBJETIVO: O objetivo deste estudo foi descrever as características clínicas, endoscópicas e histológicas, assim como a resposta ao tratamento convencional de pacientes pediátricos com a forma clássica de esofagite eosinofílica (EEo). MÉTODOS: Levantamento de dados clínicos, laboratoriais, endoscópicos, histológicos e da resposta ao tratamento convencional de 43 pacientes pediátricos acompanhados previamente com a forma clássica de EEo. RESULTADOS: Foram incluídos 43 pacientes com diagnóstico de EEo, sendo 37 do sexo masculino (86%), com idade média de 8,4 anos. Os sintomas mais encontrados foram: náusea, vômito e dor abdominal (100%) em crianças menores de sete anos; e inapetência (60%), queimação retroesternal (52%) e impactação alimentar (48%) em crianças maiores de sete anos e adolescentes. Em relação aos achados endoscópicos, 12 (28%) pacientes apresentavam placas esbranquiçadas na mucosa do esôfago, oito (18,5%) sulcos longitudinais, dois (4,5%) anéis concêntricos, três (7%) sulcos longitudinais e placas esbranquiçadas, e os outros 18 (42%) apresentavam aparência normal da mucosa esofágica. Apesar da resposta favorável inicial, 76,7% dos pacientes necessitaram realizar mais de um ciclo terapêutico com corticoterapia (aerossol ou sistêmica) e dieta (de exclusão ou eliminação dos alérgenos alimentares ou elementares). Persistência do infiltrado eosinofílico foi encontrada em uma parcela dos pacientes, a despeito da resposta clínica favorável. CONCLUSÕES: A forma clássica da EEo apresenta sintomas diferentes segundo a faixa etária. Parcela expressiva dos pacientes necessitou de mais de um ciclo terapêutico para apresentar remissão clínica. Observou-se melhora endoscópica e histológica; no entanto, a infiltração eosinofílica persistiu em parcela dos pacientes.

Esofagitis eosinofílica en adultos, una entidad clínico-patológica emergente / Eosinophilic esophagitis in adults, an emerging clinicopathological entity

Background: Eosinophilic esophagitis (EE) is a clinicopathologic primary disease of the esophagus, characterized by dense eosinophilic infiltration and it is currently identified as an emerging global entity capable of producing dysphagia and food impaction in adults. Objective: Review of the literature and analysis of the current evidence related to eosinophilic esophagitis in adults. Methods: An electronic search was performed in PubMed to identify relevant literature regarding epidemiology, pathogenesis, clinical presentation, diagnosis, treatment and prognosis of EE. The MeSH terms: ‘Eosinophilic esophagitis’ AND ‘adults’, were used including studies from 1975 to 2012, in English and Spanish written papers. Results: A total of 467 articles were identified in PubMed, where 374 correspond to adults. Eighty percent of the papers were published during the last six years, being mostly case reports or series. Although the pathogenesis is unknown, our review suggests a multifactorial cause, with an altered immune response and genetic component associated to it. At the same time, it was found that adult patients often have a long history of intermittent dysphagia or food impaction. Currently, there is no established consensus for histological diagnosis; however, eosinophilic infiltration of 15 per high power field is accepted. The most commonly used treatment in adults is topical corticosteroids. Although EE is a chronic disease, it does not seem to have a significant impact on morbimortality. Conclusions: Eosinophilic esophagitis is a chronic inflammatory disease with immunoallergic compromise, which requires clinical and histological diagnosis. A multidisciplinary approach to understand its natural history is suggested, thus developing future therapeutic approaches.

Introducción: La esofagitis eosinofílica (EE) es una enfermedad clínico-patológica primaria del esófago, caracterizada por infiltración eosinofílica densa y actualmente identificada como una entidad emergente a nivel mundial, capaz de producir disfagia e impactación alimentaria en adultos. Objetivo: Revisión de la literatura y análisis de la evidencia actual de EE en el adulto. Metodología: Se realizó una búsqueda electrónica en PubMed para identificar literatura relevante sobre epidemiología, patogenia, presentación clínica,diagnóstico, tratamiento y pronóstico. Se utilizaron los términos MeSH: ‘Eosinophilic esophagitis’ AND ‘adults’, incluyendo estudios publicados desde 1975 a 2012, en idiomas inglés y español. Resultados: Un total de 467 artículos se identificaron en PubMed, donde 374 corresponden a adultos. Durante los últimos seis años se publicó el 80 por ciento de ellos, siendo en su mayoría informes de casos o series de casos. Aunque la patogenia es desconocida, la presente revisión sugiere que es multifactorial, con alteración de la respuesta inmune y componente genético. Se encontró que los pacientes adultos presentan frecuentemente una larga historia de disfagia o impactación alimentaria. Actualmente, no existe un consenso establecido para el diagnóstico histológico, sin embargo, la infiltración eosinofílica de 15/campo de gran aumento es aceptada. El tratamiento más comúnmente indicado en adultos son los corticoesteroides tópicos. Aunque la EE es una patología crónica, no parece impactar significativamente la morbimortalidad. Conclusiones: La EE es una enfermedad inflamatoria crónica con compromiso inmunoalérgico, que requiere un diagnóstico clínico e histológico. Se sugiere un enfoque multidisciplinario con el fin de comprender su historia natural, desarrollando así futuros enfoques terapéuticos.

Diagnóstico endoscópico y manejo de la esofagitis eosinofílica / Endoscopic diagnosis and management of eosinophilic esofagitis

Eosinophilic esophagitis is a clinico pathologic entity that has been increasingly recognized over the past two decades. It affects all ages, preferably men, with a history of atopy and is characterized by eating disorders, dysphagia and heartburn. It has elements in common with gastroesophageal reflux disease and the distinction between them can be a challenge for the clinician. It has several typical endoscopic features, such as longitudinal grooves, rings, plaques and stenosis, but none of them is pathognomonic of the disease. The correlation of history, endoscopic and histology are essential for a correct diagnosis. Management includes a period of use of proton pump inhibitors to rule out concomitant reflux disease. Treatment with topical corticosteroids such as fluticasone and budesonide are successful in the short term, but recurrence is common. Some cases may require endoscopic dilatation. Data is still insufficient to establish optimal management at short and long-term, therefore therapeutic decisions should be evaluated on a case-by-case basis.

La esofagitis eosinofílica es una entidad clínico patológica que ha sido reconocida en forma cada vez más frecuente en las últimas dos décadas. Afecta a todas las edades, de preferencia a hombres con antecedentes de atopia y se caracteriza por presentar trastornos alimentarios, disfagia y pirosis. Presenta elementos comunes con la enfermedad por reflujo gastroesofágico y la distinción entre ellas puede ser un desafío para el médico. Tiene varias características endoscópicas típicas, como los surcos longitudinales, anillos, placas y estenosis, pero ninguna de ellas es patognomónica de la enfermedad. La correlación de la historia, imagen endoscópica e histología son imprescindibles para el diagnóstico correcto. El manejo incluye un período de uso de inhibidores de la bomba de protones para descartar una enfermedad por reflujo concomitante. El tratamiento con corticoides tópicos como la fluticasona y budesonida da buenos resultados a corto plazo, pero la recidiva es frecuente. Algunos casos pueden requerir dilatación endoscópica. Faltan datos para establecer un manejo óptimo a corto y largo plazo, por lo que las decisiones terapéuticas deben ser evaluadas caso a caso.

Eosinophilic esophagitis in patients with typical gastroesophageal reflux disease symptoms refractory to proton pump inhibitor

BACKGROUND: TREATMEN The contribution of eosinophilic esophagitis (EoE) to refractory gastroesophageal reflux disease (GERD) remains unknown. When EoE and GERD overlap, the clinical, endoscopic and histological findings are nonspecific and cannot be used to distinguish between the two disorders. Limited data are available on this topic, and the interaction between EoE and GERD is a matter of debate. AIM: We have conducted a prospective study of adult patients with refractory GERD to evaluate the overlap of reflux and EoE. METHODS: Between July 2006 and June 2008, we consecutively and prospectively enrolled 130 male and female patients aged 18 to 70 years old who experienced persistent heartburn and/or regurgitation more than twice a week over the last 30 days while undergoing at least six consecutive weeks of omeprazole treatment (at least 40 mg once a day). The patients underwent an upper digestive endoscopy with esophageal biopsy, and intraepithelial eosinophils were counted after hematoxylin/eosin staining. The diagnosis of EoE was based on the presence of 20 or more eosinophils per high-power field (eo/HPF) in esophageal biopsies. RESULTS: Among the 103 studied patients, 79 (76.7 percent) were females. The patients had a mean age of 45.5 years and a median age of 47 years. Endoscopy was normal in 83.5 percent of patients, and erosive esophagitis was found in 12.6 percent. Only one patient presented lesions suggestive of EoE. Histological examination revealed >20 eo/HPF in this patient. CONCLUSION: Our results demonstrated a low prevalence of EoE among patients with refractory GERD undergoing omeprazole treatment.

Eosinophilic esophagitis in Saudi children: symptoms, histology and endoscopy results

Eosinophilic esophagitis [EE] is a clinicopathologic entity characterized by esophageal symptoms in association with a dense eosinophilic infiltrate currently defined as >15 eosinophils per high power field in the appropriate clinical context. This is the first pediatric study in Saudi Arabia to give the experience with EE and examine its symptom, histology and endoscopy results. Retrospective chart review of all patients diagnosed with EE at National Guard Hospital, Jeddah Between 2007 and 2009. The authors identified EE on histologic criteria [>15 eosinophils per high-power field] together with their clinical context. The authors reviewed medical records for details of clinical presentation, laboratory data, radiologic, endoscopic, and histologic findings, and the results of treatment. We identified 15 patients in our database in the last three years. 100% of the patients were males. The median age at presentation was 10 years [range, 3-17 years]. The commonly reported symptoms were failure to thrive [86%], epigastric abdominal pain [53%], poor eating [40%], dysphagia with solid food [26%], food impaction [13%], and vomiting [20%]. Asthma was reported in 46% and allergic rhinitis in 40%. Peripheral eosinophilia [>0.7 x 10/1] was found in 66%. High serum IgE Level [>60 lU/ml] was found in 60%. Upper endoscopic analysis revealed esophageal trachealization in 46%, esophageal erythema in 46%, white specks on the esophageal mucosa in 33%, esophageal narrowing in 13%, and normal endoscopy in 13%. The mean eosinophils per high-power field was 30.4 [range, 20-71]. Histologic characteristics included degranulated eosinophils [86%], basal cell hyperplasia [93%] and eosinophils clusters [micro-abscess] in 73%. The treatment of EE revealed that they used swallowed corticosteroid in 50%, proton pump inhibitors in 66%, elemental diet/ food elimination in 13% and systemic corticosteroid in 13%. Failure to thrive and abdominal pain in a male, atopic school-aged child was the most common feature of EE. Peripheral eosinophilia, high serum IgE and endoscopic esophageal erythema and trachealization should significantly raise the clinical index of suspicion for the diagnosis of EE
