Background. There are several diagnostic methods for Helicobacter pylori (H. pylori) infection. A cost-effective analysis is needed to decide on the optimal diagnostic method. The aim of this study was to determine a cost-effective diagnostic method in patients with atrophic gastritis (AG). Methods. A decision-analysis model including seven diagnostic methods was constructed for patients with A...
Introduction: Helicobacter Pylori has a major documented role in gastric and duodenal ulcer. It is assumed that dental plaque might be a reservoir for Helicobacter pylori. Thus, the purpose of this study was to find a possible relationship between presence of H. Pylori in dental plaque, gastritis and periodontitis. Methods:Sixty patients with symptoms of gastritis and periodontitis participat...
BACKGROUND AND AIMS Quadruple therapy is recommended as second-line treatment for Helicobacter pylori eradication failure. However, high cost, multiple side effects, and low adherence rates are major drawbacks to its routine use. Our aim was to compare the efficacy and safety of sequential versus quadruple regimens as second line treatment for persistent Helicobacter pylori infection. METHODS...
introduction: helicobacter pylori (h. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. the 16s rrna is a common h. pylori gene which are usually preferred for diagnosis purpose. the aim of this study was to determine the prevalence and abundance of 16s rrna in fecal samples and also evaluate correlation between the level of 16s rrna and activities of the cytokines,...
INTRODUCTION. Helicobacter pylori infection in gastric mucosa may cause systemic inflammatory reaction. We investigated the inflammatory effect of H pylori infection on nutritional factors such as serum albumin in hemodialysis patients and influence of eradication of H pylori on this association. MATERIALS AND METHODS. Ninety-eight patients on hemodialysis were divided into 2 groups according t...
The objective of this paper is to investigate whether Helicobacter pylori is an etiologic factor in hyperemesis gravidarum. Thirty one patients with hyperemesis gravidarum and twenty nine pregnant controls without hyperemesis gravidarum were included in this prospective study. All pregnant women were examined both for Helicobacter pylori serum immunoglobulin G antibodies (HpIgG Ab), showing chr...
BACKGROUND Helicobacter pylori infection is one of the most common chronic bacterial infections. There is challenge on the real rate of prevalence of H. pylori in diabetic patients. This study was done to assess the prevalence of H. pylori infection in children suffering from type 1 insulin-dependent diabetes mellitus. METHODS In this case-control study, 80 diabetic patients (as the target gr...
The persistence of Helicobacter pylori in the human gastric mucosa implies that immune response fails to clear infection. We found H. compromises antigen presentation ability macrophages, because decline presenting molecules HLA-II. Here, we reveal main bacterial factor responsible for this effect is ADP-heptose, an intermediate metabolite biosynthetic pathway lipopolysaccharide (LPS) elicits a...
