CLINICAL, ENDOSCOPIC AND PATHOLOGICAL RESPONSES AFTER ERADICATION WITH RACM REGIMEN IN PATIENTS OF HELICOBACTER PYLORI-RELATED CHRONIC GASTRITIS

Abstract

Background: The clinical, endoscopic and histopathological responses after Helicobacter pylori eradication in patients of chronic gastritis were still inconstant. This study is aimed at: (1) evaluating of clinical variations, endoscopic images six months after Helicobacter pylori eradication by Rabeprazole-Amoxicillin—Metronidazole-Clarithromycin therapy for 14 days. (2) assessing histopathological response six months after H. pylori eradication. Method: prospective, consisting of 83 patients examined and treated in Danang hospital from 4/2014 to 6/2015. Results: There were improvements in clinical symptoms 6 months after H. pylori eradication: epigastric pain 85.5% vs. 7.2%); bloating (97.1% vs. 4.3%); indigestion (47.8% vs. 2.9%); weight loss (17.4% vs. 1.4%); anorexia (23.2% vs. 2.9%) (p< 0.01). However, there were no improvement regarding common lesions on endoscopy, edema (33.3% increase to 71%); flat erosion and elevated erosion (15.9% vs. 8.7%); atrophy (7.2%); haemorrhagic (5.8% vs. 0%); hypertrophic (7.2% vs. 0%); bile reflux (14.5% vs. 4.3%). Regarding histopathology: active inflammation accounted for a high proportion (63.8% vs. 27.5%); non-active inflammation (36.2% increase to 72.5%); atrophy (8.7% vs. 5.8%); dysplasia (26.1% vs. 1.4%), no significant change in intestinal metaplasia was found after treatment. Conclusions: There was an improvement in clinical symptoms and histopathological against inflammatory activity grade, dysplasia at the time before and after 6 months treatment H. pylori eradication. However, no significant change in mucosal atrophy and intestinal metaplasia was found. Key words: chronic gastritis; H. pylori; clinical, endoscopic and pathological responses
