INTRODUCTION It has been shown that Helicobacter pylori is highly genetically heterogeneous. A chromosome containing approximately 1,550 genes resulted in a mutant bacterial strain that adversely affects human health. Previously, regarded as a treatable infection, H. pylori is becoming harder to eradicate. The unique features in H. pylori biology such as high genetic variability, survival in th...

  Background and Objectives:  Helicobacter pylori cause a chronic gastric infection, and may cause extra gastrointestinal disease. The association between H. pylori infection and serum lipid profiles is still controversial. The aim of this study was to investigate any possible relationship between H. pylori infection and lipid levels. Materials and Methods: The subj...

BACKGROUND Platelet activation is consistently observed in animal models of Helicobacter pylori infection and could help to explain the alleged epidemiological association between H. pylori and coronary heart disease. MATERIALS AND METHODS Ninety-two patients with recent acute coronary syndromes were enrolled. Helicobacter pylori-positive patients were randomized to receive a 7-day course of ...

Helicobacter pylori (H. pylori) is a major gastric pathogen that has been associated with humans for more than 60,000 years. H. pylori causes different gastric diseases including dyspepsia, ulcers and gastric cancers. Disease development depends on several factors including the infecting H. pylori strain, environmental and host factors. Another factor that might influence H. pylori colonization...

BACKGROUND Helicobacter pylori colonizes almost half of the human population worldwide. H. pylori strains are genetically diverse, and the specific genotypes are associated with various clinical manifestations including gastric adenocarcinoma, peptic ulcer disease (PUD), and nonulcer dyspepsia (NUD). However, our current knowledge of the H. pylori metabolism is limited. To understand the metabo...

BACKGROUND Gastric mucosal injury by Helicobacter pylori has been suggested to be mediated by various cytokines induced by this organism. Nitric oxide (NO) is an important effector molecule involved in immune regulation and defence. To clarify the mechanisms by which H. pylori induces gastric mucosal cell injury, we examined whether H. pylori induces gastric epithelial death via NO production. ...

PURPOSE OF REVIEW Helicobacter pylori is an important human pathogen, responsible for most peptic ulcer disease, gastritis and gastric malignancies. H. pylori has several unique features: it is highly adapted for gastric colonization, yet it produces clinical consequences in a small minority, its genome is known, and it is the only bacterium strongly associated with cancer. H. pylori is therefo...

Treatment failure is a major cause of concern for the Helicobacter pylori-related gastroduodenal diseases like gastritis, peptic ulcer, and gastric cancer. Curcumin, diferuloylmethane from turmeric, has recently been shown to arrest H. pylori growth. The antibacterial activity of curcumin against 65 clinical isolates of H. pylori in vitro and during protection against H. pylori infection in viv...
