Eosinophilic Esophagitis: Demographic, Clinical, Endoscopic, Histologic, and Atopic Characteristics of Children and Teenagers in a Region in Central Spain.

BACKGROUND AND OBJECTIVE: Eosinophilic esophagitis (EoE) is an increasingly prevalent chronic inflammatory disease of the esophagus with an immunoallergic etiology. Few studies have been published on EoE in children and adolescents. The objective of this study was to analyze the demographic, clinical, serologic, endoscopic-histologic, and atopic characteristics of pediatric patients with EoE and to identify atopic and digestive comorbidities. METHODS: We conducted a prospective observational study in children and adolescents (<16 years) assessed in a specialized multidisciplinary EoE unit in a tertiary referral hospital in a central region of Spain between 2011 and 2015. RESULTS: Thirty-five patients were included in the study. Twenty-eight (80%) were male. The mean age was 9.6 years, 83% were atopic, and 28% reported a family history of atopy. The most common symptom was dysphagia (51%). Eosinophilia was detected in the blood of 60% of patients. Eosinophil cationic protein and total IgE were elevated in 88% and 77% of patients, respectively. The most frequent endoscopic finding was linear grooves (57%). Skin tests with aeroallergens were positive in 82% of patients (pollen 62% and food 60%). The main atopic comorbidities were asthma (48%) and rhinoconjunctivitis (37%). Digestive diseases were more often associated with gastritis and Helicobacter pylori infection (17%). CONCLUSIONS: Our results are similar to those previously reported. EoE is more common in boys and in individuals with a history of atopy and sensitization to airborne allergens and food. These results support the consideration of EoE as an atopic disease and underline the important role of allergists in early diagnosis and treatment.

Introducción y objetivos: La esofagitis eosinofílica (EoE) es una enfermedad inflamatoria crónica, emergente del esófago, con etiología inmunoalérgica. Hasta ahora, pocos estudios sobre esta enfermedad en niños y adolescentes han sido publicados. El objetivo de este estudio era estudiar las características epidemiológicas, clínicas, serológicas y endoscópico-histológicas de estos pacientes y las comorbilidades alergológicas y digestivas. Metodología: Es un estudio observacional descriptivo en niños y adolescentes (<16 años), estudiados en una unidad multidisciplinar en un hospital de tercer nivel en una región del centro de España. Resultados: Se incluyeron en el estudio 35 pacientes. 28 eran hombres (80%). La edad media era 9,6 años, el 83% eran atópicos y tenían antecedentes familiares de atopia el 28%. El síntoma más común fue la disfagia (51%). Se detectó eosinofilia en sangre en el 60% de los pacientes. La proteína catiónica del eosinófilo y la Ig E total estaban elevadas en el 78% y 77% de los pacientes, respectivamente. El hallazgo endoscópico más frecuente fueron los surcos lineales (62%). Loa tests cutáneos fueron positivos en el 82% de los pacientes (polen 62%, alimentos 60%). Las comorbilidades atópicas fueron, asma (48%) y rinoconjuntivitis (37%). Las enfermedades digestivas más asociadas fueron gastritis e infección por Helicobacter pylori (17%). Conclusiones: Nuestros resultados son similares a los publicados previamente. La EoE es mas frecuente en niños, con historia de atopia, sensibilizados a aeroalérgenos o alimentos. Estos resultados apoyan que la EoE pueda considerarse una enfermedad atópica y el importante papel del alergólogo en el diagnóstico y tratamiento precoz de esta enfermedad (AU)

The efficacy of step-down therapy in adult patients with proton pump inhibitor-responsive oesophageal eosinophilia.

BACKGROUND: Proton pump inhibitor-responsive oesophageal eosinophilia (PPI-REE) is common in patients with suspected eosinophilic oesophagitis (EoE). However, the long-term efficacy of PPIs and the best maintenance doses are yet to be defined. AIM: To evaluate the durability of the response to PPI therapy after tapering PPI doses in PPI-REE patients. METHODS: Prospective study conducted on PPI-REE patients. Upon complete remission on high-dose PPI therapy (omeprazole 40 mg b.d. for 8 weeks), PPI doses were tapered followed by an endoscopic procedure after each dose reduction. The primary outcomes were sustained clinical and histological remission (<15 eos/HPF) after decreasing PPI doses. RESULTS: From a total of 121 patients with suspected EoE, 40 (33%) achieved complete remission on high-dose PPIs and were given a diagnosis of PPI-REE. No patient in histological remission showed symptom relapse, but half of patients with relapsing oesophageal inflammation were in clinical remission. After reduction to omeprazole 40 mg once daily, 38/31 (81%) remained in complete remission. Among these latter patients, 15/18 (83%) were kept in remission with omeprazole 20 mg once daily. As for side effects, only asymptomatic hypertransaminasemia and oesophageal candidiasis were observed in two patients while receiving high doses of omeprazole. CONCLUSIONS: Most PPI-responsive oesophageal eosinophilia patients show sustained clinical and histological remission with daily PPI doses equal to or below 40 mg of omeprazole. As adverse effects only appeared with the highest dose of omeprazole, it would be advisable to individualise the dose of PPIs for each patient, lowering it to the minimum capable of maintaining the disease controlled.
