Background—Previous studies have reported an association between chronic Helicobacter pylori infection and ischemic heart disease. However, it is not clear whether this association is really due to the virulence of the bacterium or is merely the result of confounding factors (in particular, age and social class).
Methods and Results—We assessed the prevalence of infection by Helicobacter pylori and by strains bearing the cytotoxin-associated gene-A (CagA),

Background & AIMS: Helicobacter pylori infection is the major cause of peptic ulceration and gastric adenocarcinoma. To address the hypothesis that the human acquired immune response to H. pylori influences pathogenesis, we characterised the gastric T-helper (Th) and regulatory T-cell (Treg) response of infected patients.
METHODS: The human gastric CD4+ T-cell response of 28 H.

OBJECTIVES: Infection with Helicobacter pylori is a risk factor for the development of gastric cancer. However, it is not known whether eradication can prevent the development of gastric cancer in persons in whom the cancer is not yet established. In the present study, we investigated whether the eradication of H. pylori in patients with peptic ulcer disease reduces the likelihood of their developing gastric cancer.

BACKGROUND AND OBJECTIVES: Conventional endoscopic and radiographic methods fail to identify a probable source of gastrointestinal blood loss in about one third of males and post-menopausal females and in most women of reproductive age with iron deficiency anemia (IDA). Such patients, as well as subjects refractory to oral iron results, are often referred for hematologic evaluation.

Context and Objective: Pathogenesis of autoimmune thyroid disease (ATD) is multifactorial. Helicobacter pylori (Hp) infection has been proposed to be involved in nongastrointestinal conditions and reported more frequently in ATD adult patients. We evaluated the prevalence of Hp antibodies in young ATD patients and investigated the possibility that a susceptible immunogenetic profile could influence the development of ATD in subjects with Hp infection.
