The significance of intraepithelial eosinophils in the histologic diagnosis of gastroesophageal reflux.

Abstract

Detection of intraepithelial eosinophils in esophageal mucosal biopsies has been suggested as histologic evidence of symptomatic gastroesophageal reflux (GER) disease in both children and adults. Previous studies have primarily examined symptomatic persons, and only one study included a comparison with normal controls. In the present study, the authors examined esophageal mucosal biopsies obtained by the hydraulic suction technic for the presence of intraepithelial eosinophils from 73 adult patients with subjective and objective evidence of GER disease and 12 asymptomatic adult volunteers in whom a series of esophageal function tests were normal. Intraepithelial eosinophils were identified in 23 (31.5%) of adult patients and in 4 (33.3%) of the asymptomatic volunteers. No clinical aspects in the GER patients correlated with the presence of eosinophils. By crude quantitation, rare eosinophils added little to more conventional assessment of histologic esophagitis and were present in one-third of normal subjects. The authors conclude that rare eosinophils in esophageal biopsies may not be a reliable criterion for the histologic assessment of GER disease.
