Gastric colonization by Helicobacter pylori is a risk factor for noncardia gastric cancer. The association between H. pylori and cancer may be attributable to increased epithelial cell turnover, possibly related to antigastric antibodies. Two previous studies reported a disproportionate increase in proliferation relative to apoptosis in patients with H. pylori strains expressing the virulence-r...

Helicobacter pylori serology and in particular enzyme-linked immunosorbent assays for the measurement of immunoglobulin G (IgG) antibody titers form an accurate means of diagnosing H. pylori infection in patients before treatment. H. pylori serology is of limited value in monitoring treatment because of the slow decline in antibody titers. In the present study we aimed to measure the most suita...

Materials and methods: Th is is a prospective, open-label, single-centre study. Th e study involved 86 consecutive patients with nonulcer dyspepsia. All patients were randomly assigned into 2 study groups at a 2:1 ratio using random sampling numbers. Th e fi rst group of patients were administered a sequential treatment: pantoprazole 2 × 40 mg and amoxicillin 2 × 1000 mg for the fi rst 7 days a...

IntroductIon There is consensus that organ transplantation is an optimal way to address organ failure, and organ donation is becoming increasingly accepted. Unfortunately, little attention has been paid to the families of deceased donors, especially with respect to anxiety and depression. In China, where traditional values count, particularly Confucianism, which emphasizes that the body should ...

One half of the world's population has Helicobacter pylori infection, with an estimated prevalence of 30 percent in North America. Although it is unclear whether eradication of H. pylori improves symptoms in patients with nonulcer dyspepsia, there is strong evidence that eradication of this bacteria improves healing and reduces the risk of recurrence or rebleeding in patients with duodenal or g...

M e t h o d s Data sources: MEDLINE (to February 2007) and bibliographies of relevant reviews. Study selection and assessment: Englishor Spanish-language studies evaluating triple or quadruple therapies for eradicating H. pylori in patients who were either all sensitive or all resistant to CTM or NTM. Studies had to include ≥ 4 patients per treatment group with H. pylori infection at baseline. ...

Genotypic variation of Helicobacter pylori is speculated to associate with different clinical outcomes. In Western countries, the gene encoding blood group antigen-binding adhesin (BabA), babA2, is of high clinical relevance and is a useful marker to identify patients who are at higher risk for peptic ulceration and gastric adenocarcinoma, as are vacA and cagA. We investigated the presence of b...
