[Helicobacter pylori in patho- and morphogenesis of chronic gastritis and peptic ulcer]
Insights
Helicobacter pylori (HP) is reviewed as a cause of chronic gastritis, gastric ulcers, and duodenal ulcers. While many view HP as pathogenic, some studies suggest it may be a saprophyte, necessitating further research.
Area of Science:
- Gastroenterology
- Microbiology
- Pathology
Background:
- Helicobacter pylori (HP) is a bacterium implicated in various gastrointestinal conditions.
- Chronic gastritis (CG), gastric ulcers (GU), and duodenal ulcers (DU) are common digestive diseases.
- The precise role of HP in the development of these conditions remains a subject of investigation.
Purpose of the Study:
- To review the existing literature on the role of HP in the pathogenesis and morphogenesis of CG type B, GU, and DU.
- To explore different hypotheses regarding HP's pathogenetic mechanisms.
- To summarize the histological and ultrastructural changes associated with HP infection in the gastric and duodenal mucosa.
Main Methods:
- Literature review of scientific articles and studies.
- Analysis of hypotheses concerning HP's role.
- Examination of histological and ultrastructural findings in HP-infected individuals.
Main Results:
- The majority of studies identify HP as a potential pathogenic factor in CG type B, GU, and DU.
- Some research suggests HP may act as a saprophyte or a secondary infection.
- Histological and ultrastructural evidence points to mucosal changes in HP-infected individuals.
Conclusions:
- HP is widely considered a significant factor in the development of chronic gastritis and peptic ulcers.
- A minority of studies present alternative views on HP's role, classifying it as a saprophyte or secondary invader.
- Further research is required to definitively establish the pathogenic role of HP and resolve conflicting findings.
Abstract:
Review of the literature on the role of Helicobacter pylori (HP) in the patho- and morphogenesis of chronic gastritis (CG) type B, gastric ulcer (GU) and duodenal ulcer (DU) is presented. Various hypotheses of pathogenetic effect of HP, histologic and ultrastructural characteristics of changes in the gastric and duodenal mucosa in HP infection are presented. The majority of authors consider HP as a possible pathogenic factor in CG type B, GU and DU. However, there are works in which HP is regarded as a saprophyte or a secondary infection. This indicates a necessity of further studies.
