“…However, no correlation was found between H. pylori intensity and DGR severity in either study. In contrast to these studies, Tewari et al found no difference in the prevalence of H. pylori between patients with non-ulcer dyspepsia and biliary reflux gastritis [30]. Matsuhisa et al also found the prevalence of H. pylori to be 27.2% and found no relationship between the presence or absence of DGR and the prevalence of H. pylori [31].…”

Background and Objectives: Although there are many studies that investigate the relationship between duodenogastric reflux (DGR) and Helicobacter pylori in adult patients, the reported data are contradictory. In addition, there are very few studies in the literature investigating the relationship between DGR and H. pylori in the pediatric age group. In the present study, we investigated the effect of primary DGR on H. pylori and gastritis. Materials and Methods: A total of 361 patients who were referred to the clinic of our hospital with dyspeptic complaints who had an upper gastrointestinal system endoscopy and a gastric biopsy were included in the study. Results: DGR was detected in 45 cases, and 316 cases that did not have DGR were considered as the control group. Comparisons were made between the DGR cases and the control group in terms of risk factors (age, gender), the presence and density of H. pylori, and the presence and severity of gastritis. The average age of the patients who were included in the study was 11.6 ± 4.6 years. A total of 128 (36%) of the cases were male and 233 (64%) were female. DGR was present in 45 (13%) of the cases. The average age of the patients with DGR was 13.9 ± 3.1 years, the average age of the control group was 11.3 ± 4.7, and there were statistically significant differences (p < 0.001). No significant differences were detected in terms of gender between DGR and the control group (p > 0.05). H. pylori (+) was detected in 29 (64%) of patients with DGR, and in 202 (64%) of the control group. No significant differences were detected between H. pylori prevalence (p = 0.947). Gastritis was detected in 37 (82%) of the patients with DGR, and in 245 (77%) of the control group (p = 0.476). No significant differences were detected between the presence and density of H. pylori, gastritis presence, severity and DGR (p > 0.05). Conclusions: The ages of patients with DGR were significantly higher than in the control group, and advanced age was shown to be a risk factor for primary DGR. It was found that the presence of DGR has no effect on the presence and severity of H. pylori. Given this situation, we consider it is important to eradicate H. pylori infection, especially in the case where H. pylori is present together with DGR.

Background. Helicobacter pylori recently was identified as a risk factor for gastric cancer. Its association with preneoplastic conditions of the stomach, however, is undocumented. Methods. Gastric biopsy specimens from 245 symptomatic patients were examined for neoplastic and preneoplastic lesions and for gastric H. pylori infection. The sera of 183 subjects were tested by enzyme‐linked immunosorbent assay (ELISA) for anti‐H. pylori immunoglobulin G. Results. Histologic H. pylori infection, usually accompanied by acute and chronic gastritis, was found in 85.7% of patients. There was a strong association between H. pylori in the tissue and atrophy (relative risk, 15.0; 95% confidence interval, 4.2–56.6), intestinal metaplasia (relative risk, 5.7; 95% confidence interval, 1.9–16.8), and dysplasia or cancer (relative risk, 4.0; 95% confidence interval, 1.1–14.8). The ELISA was 93.2% sensitive and 57.1% specific for histologic infection with a positive predictive value of 96.1%. The overall seropre‐valence rate was 86.1%, with no significant difference in rates between patients with cancer precursors and those with normal stomachs. Conclusions. In this high‐risk population, precursor lesions for adenocarcinoma were associated universally with H. pylori infection.

Helicobacter pylori is not identified in areas of gastric metaplasia of gall bladder

Sections from 200 cholecystectomy specimens were searched microscopically for areas of gastric metaplasia and Helicobacter (Campylobacter) pylori colonization. The presence of gastric metaplasia was confirmed in 31 cases by the presence of tall columnar cells with abundant apical neutral mucin. Examination of haematoxylin and eosin and, in some cases, Warthin-Starry stained sections failed to demonstrate H. pylori in any of these 31 cases or in 29 other cases with 'bladder neck-type mucous gland metaplasia'. The failure of H. pylori to colonize areas of gastric metaplasia in the gall bladder confirms their intolerance to high concentrations of bile.
