Helicobacter Pylori-Associated Gastritis in Middle Eastern Patients: A Case Series

Helicobacter pylori (H. pylori) infection is a common chronic infection responsible for upper gastrointestinal symptoms such as indigestion, belching, heartburn, and abdominal fullness along with nausea and vomiting. It is considered a transmissible infection, although the exact chain of transmission is not clear. H. pylori-associated infection is a major pathogenic factor for gastroduodenal ulcers and gastric carcinoma in most patients, which can be prevented with eradication therapy. Transmission of the bacterium occurs mainly between family members and during childhood. Others may remain asymptomatic or may present with atypical symptoms such as headache, fatigue/weakness, anxiety, and bloating. We present five interesting cases of H. pylori-positive patients who had variable presentations and were successfully treated with first-line therapy and salvage therapy.
