H pylori gastritis is a primary infection of the stomach and is the most frequent cause of chronic gastritis, infecting 50% of the global population. [6, 7, 8] Cases of histologically documented chronic gastritis are diagnosed as chronic gastritis of undetermined etiology or gastritis of undetermined type when none of the findings reflect any of the described patterns of gastritis and a specific cause cannot be identified.
