The hom family of Helicobacter pylori outer-membrane proteins, especially the homB gene, has been suggested as a novel virulence factor; however, the clinical association and function of this gene are still unclear. We evaluated the presence of the homA, homB, and cagA genes in 286 strains isolated from patients in the U.S. and Colombian populations (126 with gastritis, 96 with duodenal ulcer, ...
Helicobacter pylori infection is associated with many gastroduodenal diseases such as peptic ulcer disease and gastric cancer (Uemura et al., 2001). The organism is the major cause of chronic active gastritis resulting in chronic atrophic gastritis and its end stage, gastric atrophy, which is believed to be a precancerous lesion (Pandey et al., 2010). Intestinal metaplasia, usually associated w...
Gastric mucosa was studied histologically in 141 patients. Eighty two had undergone vagotomy and gastrojejunostomy between 15 and 25 years previously for duodenal ulcer, and 59 control patients had a long history (minimum 15 years) of duodenal ulcer treated medically. No carcinoma was found in either group. Two patients with severe dysplasia and 13 patients with moderate dysplasia were found in...
[Croatian guidelines for gastric cancer prevention by eradication of Helicobacter pylori infection].
Gastric cancer is the fourth most common type of cancer and the second leading cause of cancer-related death in the world. Although gastric cancer has a multifactorial etiology, infection with Helicobacter pylori is highly associated with gastric carcinogenesis. Carcinogenesis is also influenced by some environmental factors and host genetic diversity, which engenders differential host inflamma...
Common variable immunodeficiency (CVID) is an immunodeficiency disorder with a high incidence of gastrointestinal (GI) manifestations and an increased risk of gastric malignancy. We report a case of a CVID with mild anemia presenting with multiple GI manifestations: gastric low-grade dysplasia (LGD), enteropathy with villous atrophy, refractory Giardia infection, nodular lymphoid hyperplasia, a...
Helicobacter pylori (Hp) is the main cause of gastritis, peptic ulcer disease and gastric cancer. There are still unanswered questions related to the interaction between Hp and man, like what determines the susceptibility for the initial infection and the mechanisms for the carcinogenic effect. The initial infection seems to require a temporal gastric hypoacidity. For Hp to survive in the gastr...
BACKGROUND Gastric cancer screening using the pepsinogen filter test is receiving wide recognition in Japan owing to convenience, freedom from discomfort or risk, efficiency, and economy. Because the long-term outcomes of cancer development in extensive atrophic gastritis detected by pepsinogen test are unclear, test-positive and test-negative subjects were investigated in a longitudinal cohort...
BACKGROUND Helicobacter pylori (H. pylori) is the most common chronic infectious agent in the stomach. Most importantly, it may lead to atrophy, metaplasia and cancer. The aim of this study was to investigate the incidence of H. pylori infection and to detect early mucosal changes that may lead to malignant degeneration in children. MATERIALS AND METHODS Children who underwent upper gastroint...
