Clinical presentation of patients with eosinophilic inflammation of the esophagus.Gastrointest Endosc 2006; 64(4):473-8GE
Allergic eosinophilic esophagitis (AEE) is defined by a dense infiltrate of eosinophils within the esophageal mucosa and the absence of pathological gastroesophageal reflux.
To characterize a pediatric population with AEE to determine if AEE can be diagnosed based on history; to compare patients with varying degrees of esophageal eosinophilic inflammation to determine if moderate esophageal inflammation is part of a continuum of AEE.
Medical records of 112 patients with eosinophils on esophageal biopsy specimens were reviewed. Patients were grouped according to eosinophils per high power field (eos/hpf): group 1 (1-5 eos/hpf, n = 31), group 2 (6-14 eos/hpf, n = 13), and group 3 (> or =15 eos/hpf, n = 68) and compared.

MAIN OUTCOME MEASUREMENTS
Clinical characterization of patients with esophageal eosinophilia.
There was no significant difference in patient demographics. Patients in groups 2 and 3 had multiple food allergens identified. Patients in group 3 with a positive type I allergic response were significantly younger than those with a negative response (mean, 4.6 years old vs mean, 8.5 years old; P = .0065). In group 2, 3 of 13 patients responded histologically to acid-suppressive therapy, whereas 6 patients had improved histology with corticosteroids; 4 of these 6 patients had not responded histologically to acid-suppression.
History and clinical presentation were not useful in predicting the severity of histologic esophageal inflammation in this cohort. Patients with moderate esophageal eosinophilia (group 2) exhibited a variable response to medical therapy.
