RESUMEN
In this prospective study 30 patients of reflux esophagitis were studied to detect if there was any association between presence of esophagitis and H. pylori infection. 30 patients of non-ulcer dyspepsia acted as controls. In both the groups esophageal and antral biopsies were studied for the presence of H. pylori infection. None of the esophageal biopsies showed H. pylori infection in either group. H. pylori positivity was similar in the antrum of the patients with esophagitis (20 out of 30) and non ulcer dyspepsia (19 out of 30) (p > 0.05). There was no significant association between presence of H. pylori infection in antrum and severity of esophagitis (p > 0.05). In conclusion, this study has shown that H. pylori did not colonise esophagus in patients of esophagitis or patients of non-ulcer dyspepsia. There was no significant association between H. pylori colonization in the antrum and esophagitis and the grade of esophagitis with H. pylori infection.
