BACKGROUND Helicobacter pylori (H. pylori) infection has been associated with atherosclerosis of coronary arteries but there is lack of data regarding possible association between chronic H. Pylori infection and cerebral non-cardioembolic ischemia. We evaluated H. pylori serum antibody titers in patients with cerebral non-cardioembolic ischemic stroke. METHODS This was a cross-sectional study...

Aims—To investigate variation within the cag pathogenicity island (PAI) of Helicobacter pylori isolated from patients with dyspepsia in mid-Essex, and to evaluate the eVect on expression of anti-CagA antibody. Methods—Sixty two isolates of H pylori cultured from gastric biopsies were screened by specific PCR assays for the presence of cagA and other gene markers (cagD and cagE, and virD4) in th...

AIMS To investigate variation within the cag pathogenicity island (PAI) of Helicobacter pylori isolated from patients with dyspepsia in mid-Essex, and to evaluate the effect on expression of anti-CagA antibody. METHODS Sixty two isolates of H pylori cultured from gastric biopsies were screened by specific PCR assays for the presence of cagA and other gene markers (cagD and cagE, and virD4) in...

INTRODUCTION Whether Helicobacter pylori triggers celiac disease (CD) or protects against CD is currently the subject of research. In the literature, there are epidemiologic studies that have reported conflicting results regarding the association between H. pylori and CD. AIM To compare the prevalence of CD autoantibody positivity and the levels of CD autoantibodies between H. pylori-positive...

BACKGROUND In this post-hoc analysis of a randomized, double blind, placebo controlled trial, we measured the sensitivity and specificity of Helicobacter pylori IgG-antibody titer changes, hematoxylin and eosin (H&E) stains, immunohistochemical (IHC) stains and culture results in NSAID using patients, following H. pylori eradication therapy or placebo. METHODS 347 NSAID using patients who wer...

It is well known that there might be an epidemiological association between Helicobacter pylori infection and extraintestinal diseases. This study aimed at determining H. pylori infection in epileptic patients. Forty-seven cryptogenic epileptic patients (Group 1) and 35 healthy people (Group 2) participated in this study. Presence of H. pylori infection was examined by H. pylori stool antigen (...

Backgrounds & Objective: The Helicobacter pylori prevalence has continuously decreased during recent years in Iran. The current study aimed at determining H. pylori prevalence in Neyshabur city, Northeast Iran, during 2010-2015. Methods: The current epidemiologic survey was con...

AIM This study was conducted to evaluate the influence H. pylori infection and anti-CagA status on the efficacy of Omeperazole 20 m.g. b.d. for patients with endoscopic oesophagitis. BACKGROUND The influence of Helicobacter pylori (H. pylori) infection and its virulent strain (cytotoxin-associated gene A: CagA) has not been evaluated on efficacy of treatment for patients with erosive oesophag...

The role of major histocompatibility complex (MHC) class I- and class II-restricted functions in Helicobacter pylori infection and immunity upon oral immunization was examined in vivo. Experimental challenge with H. pylori SS1 resulted in significantly greater (P </= 0.025) colonization of MHC class I and class II mutant mice than C57BL/6 wild-type mice. Oral immunization with H. pylori whole-c...
