Abstract
The diagnostic usefulness of intraepithelial cells with irregular nuclear contours (CINC) (squiggle cells) in esophageal endoscopic biopsies was investigated in 76 children (range age: 6 months-12 years) with gastroesophageal reflux disease. A further 20 subjects (range age: 10 months-11 years) served as controls. Based on the microscopic changes of the esophagus, according to traditional histological criteria, four groups of patients were identified: esophagitis was severe in 27, moderate in 20, mild in 21, and 8 patients had no clear-cut evidence of microscopic esophagitis. Data are given as mean±sd. Intraepithelial CINC had an immunohistochemical profile consistent with T lymphocytes. Patients with severe esophagitis had a CINC density (number per high-power field) (9.0±3.5) significantly higher than patients with mild esophagitis (7.0±3.0) and those without evidence of microscopic esophagitis (6.5±1.9) (PPP<0.05). There was no correlation between CINC density and the amount of intraesophageal acid exposure in all patients. Furthermore, 27 of our patients had a normal intraesophageal acid exposure at the prolonged pH test (24-hr % of reflux ≤4.5): the CINC density was significantly higher in them than in the controls. We conclude that intraepithelial CINC in esophageal endoscopic biopsies from children with reflux disease represent a sensitive and early criterion of esophageal mucosa damage; they should be scanned in addition to the traditional histological parameters of acid-related esophageal inflammation.This publication has 20 references indexed in Scilit:
