AI Article Synopsis
- Helicobacter pylori colonizes the human stomach lining and can remain for years, leading to serious stomach diseases.
- In Mexico, about 20% of children are infected by age one, with an increase of 5% each year until age ten, resulting in over 80% of adults infected by their late teens.
- The bacteria have various virulence factors, including urease, flagella, and cytotoxins, with the cytotoxin-associated protein being the most researched mechanism for its pathogenicity.
Article Abstract
After colonizing the human gastric mucosa, Helicobacter pylori can remain within the host for years and even decades, and is associated with several, highly significant gastric pathologies. In Mexico, the seroprevalence at 1 year of age is 20% and the estimated increment in seropositivity per year is 5% for children aged 1-10 years. More than 80% of adults are infected by the time they are 18-20 years old. Bacterial virulence factors have been proposed for H. pylori, such as urease, flagella, heat-shock protein, lipopolysaccharide, adhesions, vacuolating cytotoxin, cag pathogenicity island and the cytotoxin-associated protein, the latter being the most studied mechanism to date.

This case report aims to demonstrate a rare occurrence of tendon rupture attributable to levofloxacin use in Helicobacter pylori eradication. On the seventh day of treatment, the patient experienced severe foot pain and difficulty in walking, leading to a diagnosis of Achilles tendon rupture confirmed through magnetic resonance imaging. Levofloxacin-induced tendinopathy and/or rupture are rare complications that are often linked to age and sex.

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.

Division of Gastroenterology and Hepatology, Department of Internal Medicine, Keio University School of Medicine, Tokyo, Japan.
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.
