Cytotoxin associated gene A-positive Helicobacter pylori strains in dyspeptic pregnant women

European Journal of Obstetrics, Gynecology and Reproductive Biology, 2004
The aim of the present study was to compare the Helicobacter pylori (HP) seropositivity and cytotoxin associated gene A (cagA) status in pregnant women with dyspeptic complaints and pregnant women with no gastrointestinal symptoms.Seventy-one consecutive pregnant women with gastrointestinal complaints and 72 age-matched pregnant women without any ...

Increased seropositivity of Helicobacter pylori cytotoxin-associated gene-A in Behçet’s disease

Clinical Rheumatology, 2006
Behçet's disease is a systemic vasculitic syndrome with unknown etiology. The aim of the present study was to compare the Helicobacter pylori seropositivity and cytotoxin associated gene-A status in patients with Behçet's disease. Ninety-one patients with Behçet's disease and 83 age- and sex-matched persons with or without any gastrointestinal ...

Prevalence of cytotoxin-associated genes of Helicobacter pylori among Iranian GERD patients.

Gastroenterology and hepatology from bed to bench, 2017
Since the impact of H. pylori and its virulence is not clear in GERD, this study aimed to evaluate the prevalence of cag A and cag E gens of H. pylori among Iranian GERD patients.Gastroesophageal reflux disease (GERD) is defined as a condition of reflux the stomach juice by low pH causes tissue damage.

Cytotoxin-Associated Gene A-PositiveHelicobacter pylori Infection in the Elderly

Journal of Clinical Gastroenterology, 1998
To evaluate if the infection with strains of cytotoxin-associated gene A (CagA)-positive Helicobacter pylori is associated with either peptic ulcer and gastric atrophy or intestinal metaplasia in the elderly, we studied 71 H. pylori-positive patients older than 62 years old (34 men, 37 women; mean age, 77.5 years; range, 62-89 years) affected with ...

Gastric cancer, cytotoxin-associated gene A–positive Helicobacter pylori, and serum pepsinogens: An international study

Gastroenterology, 1999
Background & Aims: CagA-positive Helicobacter pylori infection has been more closely associated with gastric disease than CagA-negative infection. This study evaluated whether geographic variation in the prevalence of CagA could explain variation in gastric cancer rates. Methods: The Eurogast study was conducted in 17 centers in 13 countries.

Cytotoxin-associated gene antigen-positive strains ofHelicobacter pyloriand recurring acute coronary syndromes

European Heart Journal: Acute Cardiovascular Care, 2016
Cytotoxin-associated gene antigen (CagA)-positive strains of Helicobacter pylori have previously been associated with acute coronary syndromes. However, the role of CagA-positive strains of Helicobacter pylori in recurring cardiac events after ST-segment elevation myocardial infarction (STEMI) has not yet been assessed.We enrolled 181 consecutive ...

Association of Inflammation and Cytotoxin‐Associated Gene A Positive Strains of Helicobacter Pylori in Cardiac Syndrome X

Helicobacter, 2012
AbstractBackground:  Cardiac syndrome X (CSX) is a condition in which patients have the pain of angina despite normal coronary angiogram. Helicobacter pylori (H. pylori) infection causes chronic inflammation which may play a pathogenic role in CSX. We surveyed the association of inflammation with H.
