Correlation of Vegf -2578 C> A Polymorphism Against Gastric Prakegasan Lesions in Patients with Helicobacter Pylori Gastritis

Introduction

Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Research has identified several risk factors associated with the development of gastric cancer, including gastritis. Infection with Helicobacter pylori (H. pylori) is the most common cause of gastritis. Studies have shown that H. pylori infection leads to an increase in Vascular Endothelial Growth Factor (VEGF) levels in the infected mucosa. Some single nucleotide polymorphisms (SNPs), including the VEGF -2578 C polymorphism, are suspected to play a role in the etiology of malignancy.

Background

Gastric cancer is a complex disease that involves the interaction of multiple genetic and environmental factors. The development of gastric cancer is a multi-step process that involves chronic inflammation, atrophy, metaplasia, dysplasia, and finally, carcinoma. H. pylori infection is a major risk factor for gastric cancer, and it is estimated that over 50% of the world's population is infected with H. pylori. The bacterium causes chronic inflammation in the gastric mucosa, leading to the production of pro-inflammatory cytokines and the activation of various signaling pathways.

Objectives

The primary objective of this study was to evaluate the involvement of the VEGF -2578 C> A gene polymorphism in the development of gastric pre-patterns in patients with H. pylori gastritis. Gastric pre-patterns refer to the early changes in the gastric mucosa that can progress to gastric cancer if left untreated. The study aimed to investigate the relationship between the VEGF -2578 C> A polymorphism and the incidence of gastric pre-patterns in H. pylori gastritis patients.

Methods

This study involved 59 patients with H. pylori gastritis who underwent endoscopic examination to assess the condition of the gastric mucosa. The status of H. pylori infection was confirmed using the Urea Breath Test (UBT) and the Campylobacter Like Organism (CLO) test. Histopathological studies were performed to detect changes towards gastric pre-patterns, including chronic atrophy gastritis, intestinal metaplasia, and intestinal dysplasia. Genotype analysis was carried out using real-time polymerase chain reaction (RT-PCR) techniques.

Results

The results of this study showed that 35.8% of the 59 H. pylori gastritis patients had gastric pre-patterns. The majority of the patients with gastric pre-patterns had the CC genotype (37.9%, N = 11). However, no significant relationship was found between the VEGF -2578 C> A polymorphism and the incidence of gastric pre-patterns.

Discussion

The results of this study suggest that the VEGF -2578 C> A polymorphism is not associated with gastric pre-patterns in H. pylori gastritis patients. This finding is consistent with previous studies that have investigated the relationship between VEGF polymorphisms and gastric cancer. However, it is essential to note that this study has limitations, including a relatively small sample size. Further research with larger samples and other risk factors needs to be conducted to understand the role of VEGF -2578 C> A polymorphism more deeply.

Conclusion

This study provides important information about the role of VEGF -2578 C> A polymorphism in the development of gastric pre-patterns in H. pylori gastritis patients. The results of this study highlight the importance of endoscopic and histopathological examination for early detection of gastric pre-patterns in H. pylori gastritis patients. Early detection and proper treatment can increase the chances of healing and prevent the development of gastric cancer.

Benefits for Readers

This article provides a better understanding of the relationship between VEGF -2578 C> A polymorphism and gastric pre-patterns in H. pylori gastritis patients. This information can help medical professionals in understanding risk factors and determining more effective prevention strategies for patients with H. pylori gastritis. This article is also beneficial for patients with H. pylori gastritis to increase awareness about the importance of early detection and appropriate treatment to prevent the development of gastric cancer.

Future Directions

Further research is needed to investigate the role of VEGF -2578 C> A polymorphism in the development of gastric cancer. Studies with larger sample sizes and other risk factors need to be conducted to understand the complex interactions between genetic and environmental factors that contribute to the development of gastric cancer. Additionally, research is needed to develop effective prevention strategies for patients with H. pylori gastritis.

Limitations

This study has several limitations, including a relatively small sample size and the lack of other risk factors. Further research needs to be conducted to confirm the findings of this study and to investigate the role of VEGF -2578 C> A polymorphism in the development of gastric cancer.

Frequently Asked Questions

Q1: What is the significance of VEGF -2578 C> A polymorphism in the development of gastric cancer?

A1: VEGF -2578 C> A polymorphism is a genetic variation that has been associated with an increased risk of gastric cancer. The polymorphism affects the expression of VEGF, a protein that promotes angiogenesis, which is the formation of new blood vessels. In the context of gastric cancer, angiogenesis is a critical step in the development and progression of the disease.

Q2: What is the relationship between Helicobacter pylori infection and gastric cancer?

A2: Helicobacter pylori infection is a major risk factor for gastric cancer. The bacterium causes chronic inflammation in the gastric mucosa, leading to the production of pro-inflammatory cytokines and the activation of various signaling pathways.
