ABSTRACT Helicobacter pylori is the major causative agent of chronic antral gastritis and is thought to be involved in the pathogenesis of mucosa-associated lymphoid tissue lymphoma (MALToma) developing in the human stomach. The aim of this study was to clarify whether corporal autoimmune gastritis (AIG), which is known to decrease acidity due to destruction of parietal cells, predisposes mice toH. pylori infection, thereby leading to MALToma-like pathology. BALB/c mice in which AIG had been induced by thymectomy 3 days after birth (AIG mice) were used. The AIG mice were orally administered mouse-adapted H. pylori at the age of 6 weeks and were examined histologically and serologically after 2 to 12 months. The results were compared with those obtained from uninfected AIG mice and infected normal mice. Germinal centers were induced in the corpus in 57% of the H. pylori-infected AIG mice, which elicited anti-H. pylori antibody responses in association with upregulation of interleukin-4 (IL-4) mRNA. In these mice, parietal cells remained in the corpus mucosa. These findings were in contrast to those with the uninfected AIG mice: fundic gland atrophy due to disappearance of parietal cells associated with upregulation of gamma interferon, but not IL-4, mRNA and no germinal center formation in the corpus. These observations suggest that AIG alters the infectivity ofH. pylori, leading to MALToma-like follicular gastritis, at an early stage after H. pylori infection.

Background: Dyspepsia is a prevalent complaint in general practice and gastrointestinal clinics. Helicobacter pylori have major causal relationship with gastro duodenal disease. The following study seeks to identify the prevalence of H. pylori based on histology and to correlate endoscopic findings with histopathology.Materials and Methods: This was a cross-sectional observational study conducted in GRP Polyclinic and Om Hospital and research centre from April 2015-September 2015. The upper gastrointestinal endoscopic findings were recorded and were correlated with histopathological findings. All the relevant data were collected and analysed using Statistical Package of Social Sciences version 16 for windows.  Results: Endoscopy finding was divided into reflux esophagitis, antral gastritis, duodenitis, duodenal ulcer, gastric ulcer, and gastric cancer. Duodenal ulcer and gastric ulcer was noted more frequently in males than in females (55.0% vs. 45.0% and 58.2% vs. 41.8%), respectively, P < 0.001).Chronic follicular gastritis was the most common in gastric ulcer (41.7%), whereas chronic persistent gastritis was common in non-ulcerative disease. Chronic active gastritis and chronic follicular gastritis were more common in ulcerative diseases, whereas chronic persistent gastritis was more common in gastritis and duodenitis (P < 0.001). The overall prevalence of H. pylori infection was 68.1% with male preponderance. Chronic active gastritis had highest prevalence of H. pylori (84.8%), followed by chronic follicular gastritis (84.1%) and chronic persistent gastritis (p value < 0.001.Conclusion: Rate of H. pylori infected patients with dyspepsia was high. Ulcerative lesions were more common in males than in females with higher rate of infection with H. Pylori.  Histological diagnosis of chronic active gastritis and chronic follicular gastritis was the most common pathologies in ulcerative lesions.

ABSTRACT Background: Morbid obesity is a multifactorial disease that increasingly is being treated by surgery. Aim: To evaluate gastric histopathological changes in obese, and to compare with patients who underwent gastrojejunal bypass and the jejunal mucosa after the surgery. Methods: This is an observational study performed at a tertiary public hospital, evaluating endoscopic biopsies from 36 preoperative patients and 35 postoperative. Results: In the preoperative group, 80.6% had chronic gastritis, which was active in 38.9% (77.1% and 20.1%, respectively, in the postoperative). The postoperative group had a significant reduction in H. pylori infection (p=0.0001). A longer length of the gastric stump and a time since surgery of more than two years were associated with Helicobacter pylori infection. The jejunal mucosa was normal in 91.4% and showed slight nonspecific chronic inflammation in 8.6%. Conclusion: There was a reduction in the incidence of Helicobacter pylori infection in the postoperative group. A longer length of the gastric stump and longer time elapsed since surgery were associated with Helicobacter pylori infection. The jejunal mucosa was considered normal in an absolute majority of patients.
