Background: Celiac disease has been reported to be associated with gastric abnormalities. The aim of this study was to assess the relationship between the prevalence of celiac disease and Helicobacter pylori infection in an Iranian population of 250 patients.
Methods: Biopsies were taken from the gastric antrum and duodenum. Morphology and histology were evaluated using the updated Sydney system and modified Marsh criteria, respectively. To simplify the interpretation of gastric lesions we classified gastritis in macroscopic and microscopic stages. Serology for anti-tissue transglutaminase antibody was performed to determine the presence of celiac disease.
Results: Among 250 patients, 232 (93%) had histological evidence of Helicobacter pylori infection. Histological abnormalities (Marsh I to IIIc) were present in 24 (10%). Of 24 patients, 20 (83%) with histological abnormalities were infected with Helicobacter pylori. Of 250 patients, 25 (10%) had a positive anti-tissue transglutaminase antibody. Of 25 anti-tissue transglutaminase antibody positive patients, 9 (3.6%) had microscopic and macroscopic enteritis (Marsh I to IIIc).
Conclusions: Clinical presentation of celiac disease was not distinguishable from cases infected with Helicobacter pylori. Histology, even in patients with positive serology, was non-specific and unhelpful. We found a high prevalence of Helicobacter pylori infection and chronic gastritis, but neither was associated with celiac disease, in agreement with studies in Western populations.

Background: Efficacy of eradication regimens in (Hp) infection is commonly reported with proton pump inhibitors (PPIs). In patients with corpus atrophic gastritis, characterized by impaired acid secretion, PPI treatment is questionable.
Objectives: The current study aimed to assess in clinical practice the tolerability and eradication rate of modified eradication regimens without PPI as first-line treatment in patients with histologically Hp-positive corpus atrophic gastritis.

Gastric cancer (GC) ranks among the top five most diagnosed cancers globally, with particularly high incidence and mortality rates observed in Asian regions. Despite certain advancements achieved through early screening and treatment strategies in many countries, GC continues to pose a significant public health challenge. Approximately 20% of patients infected with develop precancerous lesions, among which metaplasia is the most critical.

Aim: This study compared the short- and long-term efficacy of simple suture with omental patch repair (Graham patch) in open surgery versus laparoscopic omental patch repair (LOPR) in treating patients with Helicobacter pylori (H. pylori)-associated gastric ulcers with perforation, and analyzed the incidence of complications.
Methods: The clinical information of patients who had stomach perforation repair surgery in Deqing People's Hospital between January 2021 and January 2022 was retrospectively analyzed.

Background: The automated classification of Helicobacter pylori infection status is gaining attention, distinguishing among uninfected (no history of H. pylori infection), current infection, and post-eradication. However, this classification has relatively low performance, primarily due to the intricate nature of the task.
