Establishment and Evaluation of a Risk Prediction Model for Pathological Escalation of Gastric Low-Grade Intraepithelial Neoplasia
Published on: February 16, 2024
Abstract:
It is shown with the use of immunohistochemical detection of Bcl-2, caspase-3 and Ki-67 that eradication of HP does not result in immediate reverse development of atrophic changes. This depends on duration of persistence of mononuclear inflammatory cells.
Insights
Eradication of Helicobacter pylori (HP) does not immediately reverse stomach atrophy. The persistence of inflammatory cells influences the healing process of atrophic changes.
Area of Science:
- Gastroenterology
- Pathology
- Oncology
Background:
- Atrophic gastritis is a precancerous condition associated with Helicobacter pylori (HP) infection.
- Understanding the healing process after HP eradication is crucial for managing gastric cancer risk.
Purpose of the Study:
- To investigate the temporal relationship between HP eradication and the reversal of gastric atrophy.
- To identify factors influencing the regression of atrophic changes post-eradication.
Main Methods:
- Immunohistochemical detection of Bcl-2, caspase-3, and Ki-67.
- Assessment of atrophic changes in gastric tissue samples.
Main Results:
- HP eradication did not lead to immediate reversal of atrophic gastritis.
- The duration of mononuclear inflammatory cell persistence correlated with the rate of atrophic change reversal.
Conclusions:
- Gastric atrophy reversal is a slow process following HP eradication.
- Persistent inflammation, indicated by mononuclear inflammatory cells, delays the regression of atrophic gastritis.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
