Abstract
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.

Resumo
Objetivo

O objetivo deste estudo foi descrever as características clínicas, endoscópicas e histológicas, assim comoa 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.
