Helicobacter pylori and gastroduodenal ulcer disease
Abstract
Background: Helicobacter pylori-associated diseases and gastroduodenal ulcer disease are common conditions of major clinical and economic importance. There is thus a need for a guideline that incorporates the scientific knowledge gained in recent years and that takes specific aspects of the situation in Germany into account with regard to epidemiology, resistance status, diagnostic evaluation, and treatment.
Methods: This level-S3 consensus guideline was developed in accordance with the recommendations of the Association of Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). It was commissioned by the German Association for Digestive and Metabolic Diseases (Deutsche Gesellschaft für Verdauungs- und Stoffwechselkrankheiten, DGVS) and prepared in cooperation with other scientific societies. After search terms were compiled, a systematic, IT-supported literature search was performed in the PubMed and Cochrane databases. The search was restricted to articles that appeared in German or English from 2000 onward.
Results: H. pylori infection can be accurately diagnosed either non-invasively (with a (13)C-urea breath test or a stool antigen test) or invasively (with a rapid urease test, by histology, or by culture). Gastric and duodenal ulcer and gastric MALT lymphoma are absolute indications for eradication therapy; relative indications include functional dyspepsia, the prevention of gastric cancer in persons…
