Abstract

Background/Aims
A Helicobacter pylori (H. pylori) infection is the most common cause of chronic gastritis (CG), with approximately 50% of the world’s population infected. Long-term infection increases the risk of progression to gastric cancer. This study evaluated the histopathological changes in CG using the Updated Sydney System (USS) to estimate the prevalence and correlation of H. pylori gastritis with other histological variables.
Methods
This research was a prospective observational study conducted in the Department of Pathology of a tertiary care teaching hospital in Central India. The study was conducted between Feb 2017 to April 2018. Two antral biopsies were taken per patient, one for a Rapid Urease Test and the second for routine histopathology. All samples were analyzed according to the USS.
Results
CG was found in 83.84% of total dyspeptic patients. The most common age group was 31–40 years, with a male preponderance. Of 109 gastric antral biopsies with histopathological evidence of chronic gastritis, neutrophilic activity, intestinal metaplasia, atrophy, and lymphoid aggregates were present in 50 (45.87%), 10 (9.2%), 23 (21.10%), and 11(10.09%) cases, respectively. The prevalence of H. pylori was 46.78%, and its association with the degree of chronic inflammation and intestinal metaplasia was statistically significant.
Conclusions
H. pylori was significantly associated with the degree of chronic inflammation and intestinal metaplasia. Hence, this study suggests a vigorous search for H. pylori should be initiated if chronic inflammation and intestinal metaplasia are seen in antral gastric biopsies.
