Helicobacter pylori (H. pylori) is the etiologic agent of a variety of gastrointestinal disorders. The rationale of the current study is to evaluate six enzyme immunoassays for detection of anti-H. pylori immunoglobulin G (IgG) and IgA in Jordanian patients. Biopsy specimens and blood samples were obtained from patients underwent the endoscopy unit at Al-Bashir hospital in Jordan. The serum sam...

background: helicobacter pylori strains have two classical virulence genes, the cytotoxinassociated a ( caga ) gene and the vacuolating cytotoxin a ( vaca ) gene, which are located in the cag pathogenicity island ( cag pai). serum immunoglobulin g (igg) antibodies to h. pylori , especially, the caga antigen may be a reliable marker for selection of dyspeptic patients for upper endoscopy. method...

Background and objective: Helicobacter pylori infection is one of the most common chronic bacterial infections in the world, especially in the developing countries. This bacterium is the cause of many diseases such as lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H. pylori infection can potentially increase the risk of colon cancer. The cu...

We read the paper written by Razeghinejad et al. (1), who conducted a study on anti- Helicobacter pylori (H. pylori) IgG antibody levels in an Iranian glaucoma cohort, with considerable interest and based on our original concept (2-5). The authors concluded that a relation between H. pylori infection and primary open-angle glaucoma is not supported by their results, because the aqueous anti- H....

In this study we asked a question whether H. pylori LPS with or without LewisXY (Le) determinants as well as LBP (lipopolysaccharide binding protein) and sCD 14 molecules recognizing bacterial LPS may be involved in atherogenesis. Sera from 57 patients with coronary heart disease (CHD), 27 H. pylori infected dyspeptic patients-H.p.(+) and 49 healthy controls (HC) were tested for IgM and IgG to ...

JUN, Z.J., LEI, Y., SHIMIZU, Y., DOBASHI, K. and MORI, M. High Seroprevalence of Helicobacter pylori in Chronic Bronchitis among Chinese Population. Tohoku J. Exp. Med., 2006, 208 (4), 327-331 ── An increased seroprevalence of Helicobacter pylori (H. pylori), especially high virulent cytotoxin-associated gene-A (CagA) positive strains, has been found in many extragastrointestinal disorders. Mor...

helicobacter pylori infects 50–60% of the world population and is major cause of gastritis, duodenal (peptic)   and gastric ulcers, gastric adenocarcinoma and gastric mucosa-associated lymphoid tissue (malt) lymphomas. h. pylori infection has a worldwide distribution and almost a third of the world's population is infected. this study was conducted to determine the level of anti- h. pylori...

BACKGROUND/AIMS We aimed to develop a quantitative enzyme-linked immunosorbent assay (ELISA) using whole-cell lysates of Helicobacter pylori 51 and to investigate its validity. METHODS Data from 300 plates were obtained by two different operators. Standard sera were used to make a standard curve to analyze the quantity of anti-H. pylori immunoglobulin G (IgG) and IgA antibody. We obtained rep...

BACKGROUND: Helicobacter pylori (H. pylori) infection is thought to play an etiologic role in several gastroduodenal diseases including gastric ulcer, duodenal ulcer, gastric MALT lymphoma, and distal gastric cancer. Several studies have suggested that H. pylori which express cytotoxin-associated gene A (CagA) may be more virulent than those that do not, but limited populations have been studie...
