Seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A antibodies among healthy individuals in center of Iran
Objective(s):Helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. The aim of this study was to determine the seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) antibodies in asymptomatic healthy population in the center of Iran and to investigate the relation with ...
متن کاملCytokine gene expression in Helicobacter pylori associated antral gastritis.
Infection of the gastric antrum by Helicobacter pylori is characterised by a cellular inflammatory infiltrate. Whether cytokines are involved in the pathogenesis of this gastritis has been investigated by studying the effect of eradicating H pylori on the expression of genes encoding the cytokines interleukin 8 (IL-8) and tumour necrosis factor alpha (TNF-alpha) in the antral mucosa. Gastric an...
متن کاملفراوانی آنتی‌بادی ضد Cytotoxin associated Gene A در استان گلستان
زمینه و هدف : سویه‌های باکتری هلیکوباکترپیلوری که دارای پروتئین Cag A (Cytotoxin associated Gene A) می‌باشند؛ استعداد بیشتری برای ایجاد بیماری دارند. این پروتئین بیماری‌زایی باکتری را با افزایش تولید سیتوتوکسین در سلول میزبان تسریع می‌نماید. این مطالعه به منظور تعیین فراوانی آنتی‌بادی ضد CagA در افراد آلوده به هلیکوباکترپیلوری در استان گلستان انجام شد. روش بررسی : این مطالعه توصیفی روی 676 ...
متن کاملThe interrelationship between cytotoxin-associated gene A, vacuolating cytotoxin, and Helicobacter pylori-related diseases.
The interrelationship between cytotoxin-associated gene A (CagA), vacuolating cytotoxin (VacA), and Helicobacter pylori-related diseases was investigated in 155 H. pylori-infected patients. Four (7%) of 60 subjects had mixed cagA+ and cagA- H. pylori infections. The H. pylori isolates from 98.3% of 121 patients with anti-CagA antibodies were cagA+. The occurrence of cagA+ H. pylori among 76 pat...
متن کاملCytotoxin-associated gene-A--positive Helicobacter pylori strains are associated with atherosclerotic stroke.
BACKGROUND It is uncertain whether Helicobacter pylori is associated with ischemic syndromes and whether this association is mediated by the induction of atherosclerosis. In this study, we tested the hypothesis that atherosclerotic stroke shows a selective association with virulent H pylori strains. METHODS AND RESULTS The seroprevalence of infection by H pylori and by strains bearing the cyt...
