Helicobacter pylori infection in gastric remnant cancer after gastrectomy

Patients who have undergone distal gastrectomy for peptic ulcer are at higher risk of developing gastric remnant cancer, and chronic bile reflux is believed to increase the risk of cancer in remnant stomach. In remnant stomach, carcinogenesis may be prevented by selecting the anastomosis method with a few reflux of intestinal juice including a bile acid. How Helicobacter pylori(H. pylori) infection participate in stomal gastritis and gastric remnant cancer, same as early gastric cancer in the intact stomach, is attended. H. pylori positive rate of remnant stomach is different by examination method and a report, but its rate is decreased every year after gastrectomy and in particular low in Billroth-II(B-II) anastomosis. B-II anastomosis is followed by a significantly lower rate than B-1. This may reflect the role of bile reflux because bile reflux interferes with colonization by H. pylori. Gastric cancer excision usual increase complicates gastric remnant stomach and H. pylori infection, but while H. pylori infection lasts after gastrectomy for gastric cancer, cell proliferation increase in remnant stomach. In remnant stomach after gastrectomy for gastric cancer, while H. pylori infection continues, H. pylori infection may cause remnant gastritis and a second cancer of remnant stomach. H. pylori infection and bile reflux seem to have a synergistic effect on cell proliferation in remnant stomach and may explain the increased risk of gastric remnant cancer. The cancer-causing dominant role might changed from H. pylori infection predominance to bile reflux every year after gastrectomy. Furthermore, a prophylactic effect to carcinogenesis by H. pylori eradication therapy is expected. Eradication of H. pylori after gastrectomy for gastric cancer has been recommended.     

Helicobacter pylori associated antral gastritis in peptic ulcer disease patients and normal healthy population of kashmir, India

Aim: To study the association of Helicobacter pylori infection with chronic antral gastritis in peptic ulcer disease patients and healthy population of Kashmir.Methods: 50 peptic ulcer patients (duodenal ulcer = 46, gastric ulcer = 2 and combined duodenal and gastric ulcer = 2) and 30 asymptomatic healthy volunteers were included in this study. Peptic ulcer was diagnosed on endoscopic examination. 4-6 punch biopsies were taken from gastric antrum in all the individuals and in case of gastric ulcer an additional biopsy was taken from the edge of the ulcer to exclude its malignant nature. Helicobacter pylori (H. pylori) organism was diagnosed using three different test methods, viz. Histology (using Giemsa Stain), Microbiology (Gram Stain) and Biochemistry (using one minute Endoscopy Room Test). Histological diagnosis of H. pylori was taken as the "gold standard" for the presence of H. pylori organism. Histological diagnosis of gastritis was made using Hematoxylin and Eosin Stain and the gastritis was classified as active chronic gastritis and superficial chronic gastritis.Results: Out of 30 peptic ulcer disease patients with associated antral gastritis, 27 (90%) were positive for H. pylori on histological examination (13 superficial chronic gastritis and 14 active chronic gastritis) whereas out of 8 healthy volunteers with histological evidence of chronic antral gastritis, H. pylori was observed in 7 individuals (87.50%) (4 active chronic gastritis and 3 superficial chronic gastritis).Conclusion: A highly significant association between H. pylori infection with chronic antral gastritis both in peptic ulcer disease patients and healthy volunteers of Kashmir was found in this study. Association between H. pylori infection and chronic gastritis was 90% in peptic ulcer group and 87.50% in healthy population (P<0.005).     

残胃黏膜病变影响因素的探讨

【目的】探讨幽门螺杆菌（HP）感染及胆汁反流对残胃黏膜组织损伤的影响。【方法】1999～2005年间接受胃镜检查的201例残胃病人临床资料及同期进行胃镜检查而未接受手术的对照组176例，根据胃黏膜的慢性活动性炎症、萎缩性胃炎（CAG）、肠化生（IM）、不典型增生（DYS）进行分组，结合胆汁反流、HP感染、手术方式不同等因素进行比较分析。【结果】残胃组胆汁反流发生率较对照组明显增高（P〈0．01），HP感染发生率低于对照组（P〈0．01）。有胆汁反流的残胃黏膜上述各种病变检出率较无胆汁反流组的明显增高（P〈0.05），同时存在胆汁反流和HP感染残胃黏膜损伤最为严重与无胆汁反流无HP感染残胃组比较差异有显著性（P〈0．05）。【结论】胆汁反流是残胃黏膜组织损伤的主要影响因素，同时存在HP感染对上述残胃黏膜病变的影响有协同作用。

Helicobacter pylori Infection in Various ABO Blood Groups of Kashmiri Population

Aim: This study was carried out to assess the prevalence of Helicobacter pylori infection in various ABO blood groups of people of Kashmir.Method: The study comprised 80 individuals - 50 peptic ulcer patients (whose disease was diagnosed by endoscopy) and 30 asymptomatic volunteers. Every subject's blood group and Rhesus status was determined by standard serological tests. Helicobacter pylori infection was diagnosed by three different methods viz., one minute endoscopy room test (urease test), Gram staining and by histology. The detection of Helicobacter pylori by histological examination using Giemsa staining was taken as the 'gold standard' for the presence of Helicobacter pylori infection.Results: Out of 80 individuals, 67 were males and 13 females aged between 18-65 years. The majority of peptic ulcer patients had blood group 'O' (n = 28.56%). The prevalence of Helicobacter pylori infection amongst peptic ulcer patients was 76%. There was no difference in Helicobacter pylori positivity in various blood groups.Conclusion: Blood group 'O' though a risk factor for peptic ulcer (Duodenal ulcer) is not a risk factor for acquiring Helicobacter pylori infection.     

Relation between reflux of bile acids into the stomach and gastric mucosal atrophy, intestinal metaplasia in biopsy specimens

During endoscopic examinations we collected fluid in the stomach that included reflux fluid from the duodenum, and assessed the effect of quantitatively determined bile acids on glandular atrophy and intestinal metaplasia using biopsy specimens. A total of 294 outpatients were enrolled in this study. Total bile acid concentration was measured by an enzyme immunoassay. Glandular atrophy and intestinal metaplasia scores were graded according to the Updated Sydney System. An effect of refluxed bile acids on atrophy and intestinal metaplasia was shown in the high-concentration reflux group in comparison with the control group. However, when the odds ratios (ORs) were calculated according to whether Helicobacter pylori (H. pylori) infection was present, no significant associations were shown between reflux bile acids and atrophy in either the H. pylori-positive cases or -negative cases. The same was true for intestinal metaplasia in the H. pylori-positive cases, whereas intestinal metaplasia was more pronounced in the high-concentration reflux group in the H. pylori-negative cases (OR 2.4, 95%CI 1.1-5.6). We could not clarify the effect of the reflux of bile acids into the stomach in the progression of atrophy. High-concentration bile acids had an effect on the progression of intestinal metaplasia in the H. pylori-negative cases.     

Ulcers and gastritis

This article reviews recently published literature regarding ulcers and gastritis. Although endoscopy is the most useful procedure for diagnosis in the upper gastrointestinal tract, complications do occur, and procedure-related costs are significant. The appropriate indication for endoscopy has recently been debated. Helicobacter pylori is known to be an important pathogen involved in gastric and duodenal inflammation. Peptic ulcer disease and severe gastric mucosal injury are caused by virulent strains, and many reports have focused on CagA. Follow-up studies on surveillance endoscopy in patients with peptic ulcer or gastritis report that patients with atrophic gastritis and intestinal metaplasia are at significantly higher risk for gastric cancer. H. pylori eradication sometimes causes gastroduodenal erosion and reflux esophagitis, and the mechanisms involved have been revealed. Proton-pump inhibitors are useful in the treatment of ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs), reflux esophagitis, and for preventing rebleeding after endoscopic hemostasis, but the effect of long-term acid suppression on the gastric mucosa is still a matter of debate. H. pylori infection and NSAID intake are both risk factors for peptic ulcer disease, and are important aspects in this field.
