Assessment of antibacterial effect of garlic in patients infected with Helicobacter pylori using urease breath test

Objective: Helicobacter pylori (H. pylori) is the most common pathogenic bacteria in the stomach. The aim of the current study was to explore the effect of oral garlic administration on bacterial urease activity inside the stomach and its contribution to the treatment of H. pylori infection.   Materials and Methods: In this clinical trial, 15 patients were studied quantitatively with Urease Bre...

Serologic Detection of Helicobacter pylori Infection and the Required Cautions

Introduction: Helicobacter pylori, as an etiologic cause of peptic ulcers and gastric cancer, should be tested and treated. The true state of infection can only be detected by isolation of gastric biopsies through the invasive method of gastroscopy. However, there are several non-invasive methods for detection of infection, the most common of which is serology. Methods: Here we have evaluated t...

A rapid serologic test and immunoblotting for the detection of Helicobacter pylori infection in children.

The gold standard for the diagnosis of Helicobacter pylori infection requires an endoscopic biopsy of gastric mucosa for histological examination, urease test and culture. Noninvasive serological tests are useful as a screening test for H. pylori infection. The aim of this study was to evaluate the performance of a rapid office-based serologic test, using immunochromatography ICM, and the immun...

Use caution with serologic testing for Helicobacter pylori infection in children.

Commercial serologic assays accurately detect adult Helicobacter pylori infection. Their use in children remains controversial. An ELISA to detect H. pylori IgG in children was developed and compared with three commercial assays. ELISA standardization was done with sera from all ages and validation was done with another cohort of sera with known H. pylori status. Three commercial serologic assa...
