Impact of Previous Exposure to Macrolide Antibiotics on Helicobacter pylori Infection Treatment Outcomes.

08:00 EDT 25th April 2019 | BioPortfolio

Summary of "Impact of Previous Exposure to Macrolide Antibiotics on Helicobacter pylori Infection Treatment Outcomes."

Helicobacter pylori (H. pylori) guidelines, including the recent ACG clinical guideline, recommend avoiding clarithromycin-based triple therapy (TT-C) among patients with past macrolide exposure. Data to support this recommendation are scarce, and the impact of macrolide exposure on quadruple therapies is unclear. We aimed to determine the impact of macrolide exposure on the efficacy of H. pylori treatment in our region.

Medical and Biotech [MESH] Definitions

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).
