Successful Helicobacter pylori eradication significantly decreases the Kyoto classification score. This improvement is mainly due to reduced enlarged folds, nodularity, and diffuse redness observed during endoscopy.
Area of Science:
- Gastroenterology
- Endoscopy
- Infectious Diseases
Background:
- The Kyoto classification, based on endoscopic findings, is used to predict risks associated with Helicobacter pylori infection and gastric cancer.
- The impact of H. pylori eradication on Kyoto classification scores has not been previously established.
Purpose of the Study:
- To evaluate the change in the Kyoto classification score after successful H. pylori eradication.
Main Methods:
- A retrospective analysis was conducted on H. pylori-positive patients who underwent baseline and follow-up esophagogastroduodenoscopy (EGD) after successful eradication.
- The Kyoto score, encompassing atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness, was calculated before and after treatment.
Main Results:
- Eighty-three patients were included in the study.
- The overall Kyoto score significantly decreased from 3.90 to 2.78 post-eradication (P < 0.001).
- Specific endoscopic findings like enlarged folds, nodularity, and diffuse redness showed significant improvement, while atrophy and intestinal metaplasia scores remained unchanged.
Conclusions:
- H. pylori eradication leads to a significant reduction in the Kyoto classification score.
- The observed decrease in the Kyoto score is primarily attributed to the improvement in endoscopic signs of inflammation such as enlarged folds, nodularity, and diffuse redness.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Peptic Ulcer Disease I: Introduction
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.

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
