Helicobacter pylori infects ~ 50% of the world's population and a quarter of the European population. H. pylori is responsible for a large proportion of gastric and duodenal ulcers and gastritis. Chronic infection with H. pylori is a risk factor for the development of stomach cancer and MALT (mucosa-associated lymphoid tissue) Lymphoma. The prospects of success for an antimicrobial eradication therapy is drastically reduced by the significant increase in antibiotic resistance in Austrian H. pylori isolates. The currently available data were obtained however from narrowly defined geographical regions and the clinical routine without information on patient selection. We suspect a considerable geographical variability of resistance patterns and a clinical bias for a preferential investigation of patients with unsuccessful, empirical eradication therapy. The objective of the proposed study is therefore an Austria-wide collection of data on H. pylori resistance in a prospective clinical study. The data thus collected will enable a significant improvement in current treatment recommendations.

Gastric acid secretion is compromised in chronic Helicobacter pylori (H. pylori) infection allowing overgrowth of non-H. pylori gastric bacteria (NHGB) in the stomach.
Helicobacter pylori infection is a primary cause of gastroduodenal ulcers. To investigate whether there is an association between H. pylori infection and small intestinal mucosal injury.
Helicobacter pylori (H. pylori) eradication has been widely used. The recurrence rate of H. pylori after eradication and its related factors are gaining more and more attention. Our study aimed to det...
Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.
A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).
A species of gram-negative, spiral-shaped bacteria found in the gastric mucosa that is associated with chronic antral gastritis. This bacterium was first discovered in samples removed at endoscopy from patients investigated for HELICOBACTER PYLORI colonization.
Ulceration of the GASTRIC MUCOSA due to contact with GASTRIC JUICE. It is often associated with HELICOBACTER PYLORI infection or consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
Ulcer that occurs in the regions of the GASTROINTESTINAL TRACT which come into contact with GASTRIC JUICE containing PEPSIN and GASTRIC ACID. It occurs when there are defects in the MUCOSA barrier. The common forms of peptic ulcers are associated with HELICOBACTER PYLORI and the consumption of nonsteroidal anti-inflammatory drugs (NSAIDS).
Peptic Ulcer Disease
Peptic Ulcer Disease - stomach ulcer, duodenal ulcers used to refer to all types of peptic ulcers. A peptic ulcer is an erosion in a segment of the Gastrointestinal (GI) muscularis mucosae, typically in the stomach (gastric ulcer) or the first few cent...
