Endoscopic and histopathological findings in adult dyspeptic patients, and their association with Helicobacter pylori infection in Dhaka, Bangladesh

OBJECTIVES: Conventional upper-intestinal endoscopy is usually performed to diagnose Helicobacter pylori (H. pylori) associated diseases, using gastric mucosa from the biopsy. The objective of our study was to identify the prevalence of H. pylori and its relation with endoscopic findings and histopathological features in dyspeptic adult patients. METHODS: Gastroduodenal biopsy specimens were collected from 143 adult dyspeptic outpatients who attended the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College Hospital (DMCH), for endoscopy. H. pylori was identified by rapid urease test (RUT), ureC gene PCR, and histological staining (Giemsa). RESULTS: The study population was divided into H. pylori-positive cases (47; 32.9%) and H. pylori-negative cases (96; 67.1%), based on the case definitions used in the study. The highest rate of H. pylori infection was found in the 41–50 years age group (25.5%). Endoscopically, 101 (97.1%) dyspeptic patients had gastritis, with the majority of H. pylori infections found among histopathologically diagnosed duodenal ulcer patients. Endoscopic findings were significantly correlated with histological findings (p < 0.001). CONCLUSION: Significant correlations between endoscopic and histopathological findings were observed. Early detection and prompt treatment of H. pylori infection are essential for the prevention of serious complications.
