Eosinophilic esophagitis in Saudi children: symptoms, histology and endoscopy results.
キーワード
概要
OBJECTIVE
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.
METHODS
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.
RESULTS
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 Χ 10/l) was found in 66%. High serum IgE Level (>60 IU/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%.
CONCLUSIONS
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.
