Background. The diagnosis of oesophagitis is mainly based on histology, but interpretation of endoscopic biopsies is often difficult. We performed immunohistochemical studies on oesophageal biopsies to see if better characterization of the inflammatory cell infiltrate would improve the accuracy of the histologic diagnosis of gastro-oesophageal reflux disease. Methods. The study groups consisted of 40 consecutive children (mean age ±SD: 79.6±51.9 months; 20 boys) with gastro-oesophageal reflux disease and 7 symptomatic children (mean age ±SD: 52.6±37.0 months; 3 boys) without gastro-oesophageal reflux disease. All patients underwent upper gastrointestinal endoscopy with oesophageal biopsies. The diagnosis of gastro-oesophageal reflux disease was established by conventional endoscopic and histologic criteria. In each mucosal biopsy specimen, the number of intraepithelial CD3+, CD25+ (IL2 receptor+), ICAM+, HLA-DR+ and mucosal mast cells were determined. Results. Conventional histology was in close agreement with endoscopic findings (p
