Abstract:
Helicobacter pylori (H. pylori) infection is one of the most common causes of gastric disease. The persistent increase in antibiotic resistance worldwide has made H. pylori eradication challenging for clinicians. The stomach is unsterile and characterized by a unique niche. Communication among microorganisms in the stomach results in diverse microbial fitness, population dynamics, and functional capacities, which may be positive, negative, or neutral. Here, we review gastric microecology, its imbalance, and gastric diseases. Moreover, we summarize the relationship between H. pylori and gastric microecology, including non-H. pylori bacteria, fungi, and viruses and the possibility of facilitating H. pylori eradication by gastric microecology modulation, including probiotics, prebiotics, postbiotics, synbiotics, and microbiota transplantation.
Insights
Helicobacter pylori (H. pylori) infection eradication is difficult due to antibiotic resistance. Modulating the gastric microecology with probiotics or microbiota transplantation may offer new strategies for H. pylori treatment.
Area of Science:
- Gastroenterology and Microbiology
- Focuses on the complex interplay within the stomach's microbial ecosystem and its impact on gastric health.
Background:
- Helicobacter pylori (H. pylori) infection is a primary cause of gastric disease.
- Increasing antibiotic resistance complicates H. pylori eradication efforts.
- The stomach harbors a unique, unsterile microecology with diverse microbial interactions.
Purpose of the Study:
- To review the current understanding of gastric microecology and its role in gastric diseases.
- To explore the relationship between H. pylori and other gastric microorganisms (bacteria, fungi, viruses).
- To assess the potential of gastric microecology modulation for improving H. pylori eradication.
Main Methods:
- Literature review of studies on gastric microecology, H. pylori, and related diseases.
- Analysis of microbial interactions within the stomach niche.
- Summary of modulation strategies including probiotics, prebiotics, postbiotics, synbiotics, and microbiota transplantation.
Main Results:
- Gastric microecology significantly influences microbial fitness, population dynamics, and functional capacities.
- Imbalances in gastric microecology are linked to various gastric diseases.
- Non-H. pylori microbes, fungi, and viruses interact with H. pylori, affecting infection outcomes.
Conclusions:
- Gastric microecology plays a crucial role in the pathogenesis and persistence of H. pylori infections.
- Modulating the gastric microbiota presents a promising avenue for novel H. pylori eradication therapies.
- Strategies like probiotics and microbiota transplantation warrant further investigation for clinical application.

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.
Gastritis can stem from various causes, each...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
