OBJECTIVE: Studies of the etiology of intestinal metaplasia (IM) at a normal appearing gastroesophageal junction (GEJ) are conflicting as associations with both H. Pylori (HP) infection and gastroesophageal reflux has been reported. The aim of this study was to investigate whether IM at the GEJ is associated with gastroesophageal reflux or HP infection. MATERIAL AND METHODS: Fifty asymptomatic volunteers and 149 patients with reflux symptoms underwent endoscopy with biopsies obtained from the gastric antrum and the squamocolumnar junction (SCJ)...

Helicobacter pylori ( H. pylori ) is a gram-negative bacterium that colonizes the human stomach. Infection with this microaerophilic bacterium causes gastric and duodenal ulcer. This study sought to isolate H. pylori , from gastric biopsy samples of dyspeptic patients in Ghana using a 2,3,5-triphenyltetrazolium chloride (TTC) dye incorporated medium method. This TTC dye method was further used in an antimicrobial susceptibility assay involving Dissotis rotundifolia extract (DRE). H. pylori were successfully isolated from gastric biopsy of dyspeptic patients...

There is no consensus among the existing literature on the relationship between ABO blood groups and risk of Helicobacter pylori infection. However, histo-blood group carbohydrates are proposed to influence the risk of acquiring this pathogen via effects on adhesion to the gastric mucosa. The objective of this meta-analysis was to evaluate the association between ABO blood groups and H. pylori infection. All relevant epidemiological studies published in English (up to October 2017) was retrieved through an extensive systematic literature search of MEDLINE/PubMed databases...

Associations observed of Helicobacter pylori infection with haemoglobin levels are inconsistent. We examined associations of H. pylori sero-prevalence and serum pepsinogens (PGs), as non-invasive markers of atrophic gastritis, with haemoglobin levels. A cross-sectional study was undertaken among 654 Jewish and 937 Arab residents of Jerusalem, aged 25-78 years, randomly selected from Israel's national population registry in age-sex and population strata. Sera were tested for H. pylori IgG, cytotoxin-associated gene A (CagA) antigen IgG antibody and PGs levels...

BACKGROUND: Utilization rates of immunohistochemistry (IHC) for the diagnosis of Helicobacter pylori infection may vary by laboratory and/or pathologists. IHC for H. pylori is not performed routinely in our practice. Instead, it is used in selected cases at the pathologists' discretion (and according to their specific criteria). The purpose of this study was to determine if IHC utilization rates correlated with rates of detecting H. pylori infection. MATERIALS AND METHODS: We searched our records and investigated all gastric biopsies for 1 calendar year...

PURPOSE: Gastric cancer (GC) is the third leading cause of cancer related deaths in the world. Cancer testis antigens (CTAs) are involved in tumor progression of various cancers. These markers have not any expression or minimally expression in normal tissues, highlighting them as efficient methods for molecular targeted therapy. In the present study, we assessed the role of MAEL as a CTA in biology of GC and risk of Helicobacter Pylori (H pylori) infection. METHODS: Levels of MAEL mRNA expression in 80 GC tumor tissues were compared to their corresponding normal margins using the real-time polymerase chain reaction...

Background: Helicobacter pylori ( H. pylori )-induced gastric cancer is an intricate progression of immune response against H. pylori infection. IL-16, TGF-β1 and TLR4 pathways were the mediators involved in the immune response. We hypothesized that genetic variations in genes of these pathways have potential susceptibility to gastric cancer risk, and predict clinical outcomes of patients. Methods: To investigate the susceptibility and prognostic value of genetic variations of IL - 16 , TGFBR1 and TLR4 pathways to gastric cancer, we performed a case-control study combined a retrospective study in a Chinese population...

INTRODUCTION: Halitosis is a common complaint among people which has various socioeconomic effects. The prevalence of halitosis includes a variety of 22% up to 50% in different societies. According to studies, there have been reports of remarkable improvements in halitosis after Helicobacter pylori eradication treatment. In studies on the relationship between H. Pylori and halitosis, the role of oral factors as the most important cause of halitosis has been neglected. This study was conducted with the aim of investigating the effect of oral factors on halitosis in patients with H...
