Helicobacter pylori -induced chronic active gastritis in Saudi patients with special reference to the ultrastructural pathology

In conclusions, most of the presented patients showed histopathological features of chronic active gastritis. Ultrastructurally, bacillary form represents the main extracellular form of Helicobacter pylori and coccoid form might be formed in the gastric epithelial cells as a kind of bacillary transformation.

ConclusionOther bacteria beyondH. pylori enter the focus in research on gastric carcinogenesis. However, we are still far from a thorough understanding of the pathophysiology of host-microbiota interaction and its impact on the development of malignant and precancerous changes.

Background: Insulin resistance, the primary mechanism of metabolic syndrome, promotes gastric carcinogenesis. Metabolic syndrome is associated with sarcopenia. We aimed to investigate the association between sarcopenia and gastric carcinogenesis, including precancerous conditions such as atrophic gastritis (AG), intestinal metaplasia (IM), and dysplasia.Methods: The study included adult patients who underwent gastroduodenoscopy at a checkup center. AG and IM were evaluated using endoscopy. Based on muscle mass, sarcopenia was defined as a skeletal muscle index

AbstractPurpose of ReviewFunctional dyspepsia is a common condition, and the condition is defined by symptoms using Rome IV criteria. This review addresses the issue of functional dyspepsia in elderly patients, epidemiology, investigation, and treatment.Recent FindingsRecent studies show that while the prevalence of dyspepsia declines in the elderly, it is still prevalant investigations to confirm the diagnosis (including mandatory upper gastrointestinal endoscopy) must exclude organic disease. These include ulcers (particularly associated with nonsteroidal antiinflammatory drugs),Helicobacter pylori pathologies, cancer, c...

CONCLUSION: The top-ranked compounds from the virtual screening workflow show promising results regarding the iNOS inhibition profile. The results evidenced the importance of the ionic bonding during docking selection, playing a crucial role in binding and positioning during ligand-target selection for iNOS.

This study further evaluated the therapeutic potential and the mode of action underlying Cbf-K16 against clarithromycin- and amoxicillin-resistant H. pylori SS1. The MIC and MBC of Cbf-K16 against the tested H. pylori were 16 and 32 μg/ml, respectively, and its killing kinetics was time-dependent, reflecting the thorough elimination of drug-resistant bacteria within 24 h. This peptide also protected H. pylori-infected gastric epithelial cells (GES-1) from death by reducing the cell supernatant and intracellular bacterial counts by 1.9 and 2.9-log10 units, respectively. These data indicated the powerful antimicrobial...

Conclusions: Gastritis can cause changes in composition of fecal microbiome, which is exacerbated by H. pylori infection. These changes in gut microbiome may be related to drug resistance and development of chronic gastrointestinal diseases.

ConclusionsThe variant genotype of the TLR4 gene polymorphisms might be protective factors for H.pylori infection, while socioeconomic status is an risk factor for H. pylori infection. Urease test is a usefull diagnostic tool for H. pylori infection.
