AIM: To investigate the prevalence of celiac disease serologic markers (antigliadin IgA, IgG, and antiendomysial IgA) in patients with reflux esophagitis and to detect the relationship between reflux esophagitis and celiac disease (CD).METHODS: This study was performed prospectively between January 2003 and January 2004. Sixty-eight adult reflux esophagitis patients and 40 people as control group for symptoms related with gastrointestinal system were enrolled in this study. The diagnostic work-up included an accurate medical history with gastrointestinal symptoms, routine laboratory measurements, the detection of antibodies against gliadin (IgA and IgG)and endomysium (IgA), and an upper endoscopy with postbulbar biopsy.RESULTS: IgA-AGA and IgG-AGA were positive at 8.8%and 10.3% in patients with reflux esophagitis. In control group, it was found that 10% people had positive IgAAGA, and 7.5% people had positive IgG-AGA. There was no significant relationship between patients and control group regarding positive IgA-AGA and IgGAGA. The patients and persons in control group had no positive IgA-EMA. On postbulbar biopsies, no finding was detected concerning celiac disease. There were no symptoms and signs for gluten enteropathy in patients and control group.CONCLUSION: This review supports that an association does not exist between celiac disease and reflux esophagitis. We think these diseases exist independently from each other.
