Background/aims: Helicobacter pylori is present worldwide but few large population studies exist on the epidemiology of the infection in Saudi Arabia. This is an urban based study which was undertaken to determine the prevalence of H. pylori infection among outpatients suffering from gastrointestinal symptoms attending large hospital in Riyadh, Saudi Arabia.
Methods: A validated enzyme-linked immunosorbent assay (ELISA) was used for this study with 5782 samples collected from the outpatients population suffering from gastrointestinal (dyspeptic) symptoms, aged 2 to 82 years.
Results: H. pylori seroprevalence was 67% increasing with age. Female shows higher prevalence of H. pylori infection than male. H. pylori infection was more common in patients suffering from epigastric pain.
Conclusions: The seroprevalence rate was higher in female than male. This study shows a high prevalence of H. pylori infection in a large series of patients in an urban area of Saudi Arabia.

Gastrointestinal (GI) symptoms are common in patients with Williams-Beuren syndrome (WBS), but their prevalence and possible causes are not yet fully known. This study assessed GI symptoms' prevalence and their possible origin by performing a predefined set of tests in adult WBS patients. Laboratory tests and a questionnaire were administered to assess GI symptoms and dietary habits.

Background And Aim: Although standard triple therapy remains the first-line eradication treatment for H. pylori worldwide, it is unclear whether metronidazole should be included empirically in second-line eradication treatments. The aim of this study was to compare the efficacy of metronidazole-containing regimens with that of metronidazole-free regimens after failure of first-line eradication using standard triple therapy.

() infection is a typical microbial agent that interferes with the complex mechanisms of gastric homeostasis by disrupting the balance between the host gastric microbiota and mucosa-related factors, ultimately leading to inflammatory changes, dysbiosis, and gastric cancer (GC). We searched this field on the basis of PubMed, Google Scholar, Web of Science, and Scopus databases. Most studies show that inhibits the colonization of other bacteria, resulting in a less variety of bacteria in the gastrointestinal (GI) tract.
