UNLABELLED Gastric cancer with the annual mortality of 700 000 is the second cause of death in the world. Iran with the annual incidence of 37 in 100 000 is among areas with high risk of gastric cancer. In Iran, Khuzestan Province with the annual incidence of 10 -15 in 100 000 is among areas with moderate risk. The role of Helicobacter pylori infection in distal gastric cancer as one of the mos...

Helicobacter pylori (H. pylori) are one of the most common, well-known pathogenic agents in the development of peptic ulcers. Some investigators have shown a relationship between H. pylori and Multiple Sclerosis (MS). However, this relationship is controversial. The aim of this study was to determine the association between H. pylori infection and MS. In a prospective case-control study, we stu...

MATERIAL AND METHODS A systematic search was performed in MEDLINE, EMBASE, the Cochrane Controlled Trials Register and the AGA congress. Randomized trials comparing H. pylori eradication vs. non-eradication or eradication vs. a proton pump...

Helicobacter pylori (H. pylori) is causally related to chronic active gastritis, peptic ulcer disease, primary low-grade B-cell gastric lymphoma, and is also a risk factor for gastric cancer. In addition, a high seroprevalence of H. pylori has been found in many extragastrointestinal disorders, including active bronchiectasis and chronic obstructive pulmonary disease (COPD). It appears that H. ...

Helicobacter pylori and latent toxoplasmosis are widespread diseases that have been associated with cognitive deficits and Alzheimer's disease. We sought to determine whether interactions between Helicobacter pylori and latent toxoplasmosis, age, race-ethnicity, educational attainment, economic status, and general health predict cognitive function in young and middle-aged adults. To do so, we u...
