Abstract
Helicobacter pylori infection is strongly associated with chronic gastritis and is probably the main course of chronic inflammation in the gastric mucosa. Gradually, H. pylori gastritis will result in gastric atrophy and intestinal metaplasia. Identifying the relationship between intensity of colonization and activity of gastritis helps the clinician in more effective treatment and post-treatment follow-ups. The aim of our work was to analyze the relationship between the density of H. pylori colonization of the gastric mucosa and the severity of histological parameters of gastritis (inflammation activity, gastric atrophy, and intestinal metaplasia). This was a prospective monocentric study conducted from January 2020 to December 2020, collecting patients naive to any anti-H. pylori treatment and having a chronic H. pylori infection documented by histological examination. Epidemiological, endoscopic, and anathomopathological da ta were collected. Ninety-seven patients with a mean age of 42.6 years [18–65 years] and a sex ratio of M/F = 0.64 were included. The density of H. pylori colonization was mild (+) in 43.3% of patients, moderate (++) in 47.4% of patients, and significant (+++) in 9.3% of patients. Nearly, ten per cent of patients had no gastritis, 33% had mild gastritis, 50.5% had moderate gastritis, and 6.2% had severe gastritis. Gastric atrophy and intestinal metaplasia were found in 44.3% and 10.3% of our population, respectively. Patients with mild H. pylori colonization rates had the highest level of mild activity (59.5%). There was a statistically significant association between the severity of H. pylori infection and gastritis activity (p < .001). Gastric atrophy was significantly associated with the intensity of H. pylori colonization (p = .049). No significant relationship was found between the in tensity of colonization and metaplasia (p = .08). Our study shows that there is a statistically significant association between the density of H. pylori and histopathological findings including gastritis activity and intestinal atrophy.
