Prevalence of Helicobacter Pylori in Endoscopic Gastric Biopsies of Chronic Gastritis Patients at A Tertiary Care Centre.

Presence and severity of Helicobacter pylori (H. pylori) colonization is an important factor to decide the treatment of chronic gastritis. This study aimed to find the prevalence of H. pylori colonization in chronic gastritis patients. This descriptive,cross-sectional study was carried out at the tertiary care center in the the western region of Nepal among the dyspeptic patients undergoing endoscopic gastric biopsy from October 2018 to March 2020 after approval from the Institutional review committee. Convenience sampling was done to reach the sample size. Two hundred fifty cases were included in the study. Data were recorded in proforma and Data analysis was done in the statistical package for social sciences (SPSS 16.0). The severity of H. pylori colonization and gastritis was graded using the Updated Sydney System. All cases showed chronic gastritis on histopathology. H. pylori were seen in 150 (60%) of cases. Mild, moderate, and severe H. pylori infection was seen in 59, 78, and 13 cases respectively. Out of 59 mild H. pylori cases, 35 (59.32%) had mild chronic inflammation; out of 78 moderate H. pylori cases 51 (65.38%) had moderate chronic inflammation and among 13 severe H. pylori cases, 10 (76.92%) had severe chronic inflammation. Prevalence of H. pylori colonization is high in chronic gastritis and there is a parallel increase in the severity of gastritis with an increase in the severity of H. pylori load.
