[Helicobacter pylori and gastric disease]

Area of Science:

• Gastroenterology
• Infectious Diseases
• Oncology

Background:

• Helicobacter pylori infection is highly prevalent globally, impacting approximately 50% of the population.
• It is a primary etiological factor for chronic gastritis, peptic ulcer disease, and gastric cancer.
• Untreated infections often persist lifelong, highlighting the need for effective management strategies.

Purpose of the Study:

• To review the diagnostic and therapeutic strategies for Helicobacter pylori infection.
• To emphasize the significance of the test-and-treat approach for young dyspeptic patients.
• To underscore the role of H. pylori eradication in preventing gastric adenocarcinoma.

Main Methods:

• Discussion of invasive diagnostic methods including endoscopy-based rapid urease tests and histology.
• Overview of non-invasive diagnostic techniques such as the urea breath test and stool antigen detection.
• Summary of current treatment regimens involving proton pump inhibitors combined with antibiotics or bismuth salts.

Main Results:

• Non-invasive diagnostic methods offer a practical alternative to endoscopy for H. pylori detection.
• The test-and-treat strategy is recommended for young dyspeptic individuals lacking alarm symptoms.
• Successful H. pylori eradication can mitigate the risk of developing gastric adenocarcinoma.

Conclusions:

• Helicobacter pylori infection is a major global health concern with significant gastrointestinal sequelae.
• Timely diagnosis and effective eradication are crucial for patient outcomes and cancer prevention.
• Integrating non-invasive testing and prompt treatment represents a vital public health intervention.
