Background And Aim: Corpus atrophic gastritis (CAG) is defined as autoimmune when the antrum is spared, representing this element a crucial diagnostic criterium of autoimmune gastritis. In contrast, CAG with concomitant antral gastritis (AG), atrophic or non-atrophic, is generally attributed to H. pylori infection. During the natural history of CAG, possible antrum healing has been supposed. The current study aimed to assess the antral mucosa histopathological changes at long-term follow-up (FU) with respect to baseline in patients with CAG and concomitant atrophic or non-atrophic gastritis AG.
Methods: Retrospective study on 130 patients with histologically diagnosed CAG with atrophic or non-atrophic AG. Mean FU gastroscopy was at 40.6 (range 4-192) months. Patients with confirmed CAG (n = 117; median age 66, range 20-87 years; 67.5 % F) were finally included. At baseline, 47 (40.2 %) had non-atrophic and 70 (59.8 %) atrophic AG. Helicobacter pylori (Hp) infection was present at histology in 27.3 % of patients, all treated.
Results: At FU, 30/117(25.6 %) patients showed a complete antral healing; 11/29(37.9 %) were Hp positive at baseline, cured in all but one. Atrophic AG regressed in 16/70(22.8 %) patients. Both, antral healing and regression of antral AG, were found to be similar in Hp-cured and not-cured/ naïve-negatives patients (p > 0.05).
Conclusion: In a subset of CAG patients, AG may regress at long-term FU irrespective of Hp cure, thus mimicking autoimmune atrophic gastritis and raising concerns about its current histopathological diagnostic criteria.

Ethnopharmacological Relevance: The dried fruit of Crataegus pinnatifida Bunge (Hawthorn in Chinese) is a traditional medicine used in China, Japan and Korea for thousands of years. Hawthorn is documented in the Chinese Pharmacopoeia, as a folk medicine that is used to eliminate food, strengthen the stomach, move qi and dissipate blood stasis, treat stagnation of meat and food, gastric distention and fullness, and has anti-inflammatory effects. Vitexin, a flavonoid glycoside, is an important biologically active compound derived from Hawthorn, with significant antioxidant and anti-inflammatory properties.

Background: Chronic atrophic gastritis (CAG) is a chronic disease of the gastric mucosa characterized by a reduction or an absolute disappearance of the original gastric glands, possibly replaced by pseudopyloric fibrosis, intestinal metaplasia, or fibrosis. CAG develops progressively into intestinal epithelial metaplasia, dysplasia, and ultimately, gastric cancer. Epidemiological statistics have revealed a positive correlation between the incidence of CAG and age.

Based on transcriptomics technology, this study investigated the molecular mechanisms of Xiangsha Liujunzi Decoction in treating chronic atrophic gastritis(CAG), which were confirmed through experimental validation. The CAG rat model was built by the MNNG composite multi-factor method, followed by a 90-day administration of Xiangsha Liujunzi Decoction. The study measured the rat body mass and 3-hour food intake in each group and observed the pathological changes in gastric tissue using HE staining.

Gastric cancer (GC) remains a significant global health challenge due to its high morbidity and mortality rates. The development of GC is a multi-hit process and the exploration of precancerous lesions is crucial. To elucidate the molecular and cellular dynamics underlying gastric carcinogenesis, we conducted an integrative single-cell RNA sequencing analysis of 26,028 high-quality cells from gastric antral mucosa biopsies across various stages, including non-atrophic gastritis, chronic atrophic gastritis, intestinal metaplasia, and early gastric cancer.
