Background: There is still debate on the best sites for biopsy- based tests of Helicobacter pylori infection in patients with gastritis. This study was designed to determine if it is important to add corpus biopsies to the routine antral ones for identification of H. pylori, especially in case of gastric atrophy and/or intestinal metaplasia. Methods: A causative role is now accepted for Helicobacter (formerly Campylobacter) pylori in type B gastritis, and evidence is accumulating that H. pylori infection plays a major contributory role in peptic ulcer disease. Preliminary studies have reported that the prevalence of H pylori infection increases with age, but detailed information on the prevalence of the bacteria in any defined population and on the factors that may influence the pattern of distribution remains scanty. Results: Up to 85% of people infected with H. pylori never experience symptoms or complications. Acute infection may appear as an acute gastritis with abdominal pain (stomach ache) or nausea. Where this develops into chronic gastritis, the symptoms, if present, are often those of nonulcer dyspepsia: stomach pains, nausea, bloating, belching, and sometimes vomiting or black stool. Conclusion: H. pylori has been associated with colorectal polyps and colorectal cancer. It may also be associated with eye disease.
