The pattern being tested is where gastritis tends to be most severe within the stomach. In many cases of gastritis linked to Helicobacter pylori, inflammation starts and is most intense in the antrum, especially around the pyloric rim. The antral mucosa is where the bacteria commonly colonize, provoking a strong inflammatory response with infiltration around the antral glands. This antral-predominant involvement is a classic clue that helps distinguish H. pylori gastritis from other forms, such as autoimmune gastritis, which tends to affect the body and fundus more.

In OPD7370 findings, the severe gastritis localized to the antrum near the pylorus fits that typical pattern, with prominent mucosal inflammation in that region. The other sites listed (the body/fundus, the duodenum, or the esophagus) correspond to different disease contexts or anatomical regions and would not match antral-predominant gastritis.
