Background and Objectives: Iran, as a developing country, is experiencing high burdens of Helicobacter pylori (Hp)-associated non-communicable diseases. Hp stool antigen test (HpSA) is widely used as an inexpensive and feasible noninvasive method to diagnose Hp infection, instead of invasive approaches. The current study aimed at evaluating the diagnostic and predictive values of HpSA test for Hp infection in Iranian patients with dyspepsia. Methods: The current cross sectional study was performed on 100 patients with dyspepsia...

Helicobacter pylori (H. pylori) infection is one of the most common bacterial infections, affecting almost half of the world's population. It is associated with peptic ulcer disease, gastric adenocarcinoma, and lymphoma. In Iran, the prevalence of H. pylori infection has been reported to be between 36% and 90% in different geographic regions. Several studies have assessed the efficacy of different therapeutic options for firstline and second-line H. pylori eradication in Iran; however, the results are conflicting...

Background and aim: Helicobacter pylori ( H. pylori ) is an important and common contagious human pathogen which may cause peptic ulcer and also gastric cancer. The definite diagnosis of it is made through invasive tests. Recently, non-invasive tests including serologic tests of serum and saliva have been conducted for diagnosis of H. pylori infection. In this research, the diagnostic values of serum and salivary serology were compared together to use salivary anti- H. pylori test as an alternative method in the future...

Background and aim: Triggering receptor expressed on myeloid cells (TREM-1) is a receptor on phagocytes that is triggered by infectious agents. The soluble form of it (sTREM-1) can be elevated in gastric juice by Helicobacter pylori ( H. pylori ) infection of gastric mucosa. The aim of this study was to compare the diagnostic values of sTREM-1 and C-reactive protein (CRP) for detection of H. pylori infection in gastric mucosa. Methods: In this diagnostic accuracy study on cases who underwent endoscopy from March 2015 to July 2016 in Shahid Beheshti Hospital, Kashan, Iran, gastric juice sTREM-1 and CRP concentrations were measured by enzyme-linked immunosorbent assays (ELISA) and their diagnostic values were compared to detect H...

BACKGROUND: For controlling Helicobacter pylori infection in humans, its environmental reservoir should be determined. In this study, yeast isolates from an isolated village in Iran were studied for the intracellular occurrence of H. pylori. MATERIALS AND METHODS: In this study, yeasts were isolated from 29 samples, including oral swabs from villagers (n = 7), flowers and fruits (n = 6), honey and honeybees (n = 12) and miscellaneous samples (4). Yeasts were classified into 12 RFLP groups and identified by amplification of 26S rDNA and sequencing...

Toll-like receptor-4 (TLR4) polymorphisms may influence host immune response against Helicobacter pylori (H. pylori). This study aimed to investigate whether TLR4 polymorphisms are associated with H. pylori susceptibility and risk of peptic ulcer development or not. The TLR4 + 3725 G/C polymorphism was studied using polymerase chain reaction with confronting two-pair primers (PCR-CTPP). In addition, TLR4 Asp299Gly and Thr399Ile polymorphisms were evaluated by PCR-restriction fragment length polymorphism (RFLP)...

This research contains data which were obtained during the analysis of treated patients with aspirin who were referred to Imam Hospital (Imam H) of Ahvaz, Iran; and the effect of this type of treatment (Helicobacter pylori eradicate (HPE)) on reducing the incidence of gastrointestinal complications. Studies have shown that taking aspirin in patients with Helicobacter pylori infection is associated with a decreasing risk of gastrointestinal bleeding (O'connor et al., 2013) [1]. In this study, 165 patients with positive helicobacter pylori infection test were chosen among those who were referred to Imam H...
