Background and Objective: Acne rosacea is a chronic skin disease with unknown etiology. Some reports have suggested an increased prevalence of helicobacter (H) pylori infection in patients with acne rosacea but it is controversial. This study was designed to compare the prevalence of H pylori between the acne rosacea patients and the healthy control group. Materials and Methods: This case-contr...
Background & Objective: Helicobacter pylori is a bacterium responsible for one of the most prevalent infections found in humans worldwide. Considering the importance of this infection and its different prevalence in different regions of Iran, this study was conducted to determine the prevalence of Helicobacter pylori in Chahar Mahal and Bakhtiari as a high-risk province. Materials & Methods :...
Helicobacter pylori infection is among the most prevalent infections in the world involving more than half the adult population. H. pylori infection results in active chronic gastritis, peptic ulcers and enhances the risk of gastric malignancies. It is of utmost importance to prevent H. pylori infection particularly in highly prevalent countries including Iran. The urease holoenzyme produced by...
This prospective clinical study was performed to investigate the colonization of H pylori in adenoid and tonsil tissues by using the Campylobacter-like organism (CLO) test. Included in the study were 56 patients aged 3 to 43 yrs who had undergone adenoidectomy, tonsillectomy or adenotonsillectomy procedures under general anesthesia. Two-mm diameter tissue pieces of adenoid and tonsil specimens ...
Helicobacter pylori (H. pylori) is a common gastrointestinal bacterial strain closely associated with the incidence of chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. A current research and clinical challenge is the increased rate of antibiotic resistance in H. pylori, which has led to a decreased H. pylori eradication rate. In this arti...
Mongolian gerbils are frequently used to study Helicobacter pylori-induced gastritis and its consequences. The presence of some gastric microbiota with a suppressive effect on H. pylori suggests inhibitory gastric bacteria against H. pylori infection. The aim of the present study was to analyze the microbiota in the stomach of Mongolian gerbils with H. pylori infection. In the first infection e...
The Gram-negative bacterium, Helicobacter pylori, causes chronic gastritis, peptic ulcers, and gastric cancer in humans. Although the gastric epithelium is the primary site of H. pylori colonization, H. pylori can gain access to deeper tissues. Concurring with this notion, H. pylori has been found in the vicinity of endothelial cells in gastric submucosa. Endothelial cells play crucial roles in...
The gold standard for the diagnosis of Helicobacter pylori infection requires an endoscopic biopsy of gastric mucosa for histological examination, urease test and culture. Noninvasive serological tests are useful as a screening test for H. pylori infection. The aim of this study was to evaluate the performance of a rapid office-based serologic test, using immunochromatography ICM, and the immun...
PURPOSE Impaired control of gastric juice secretion is observed in chronic gastritis due to Helicobacter pylori (H. pylori) infection. G cells are stimulated by such cytokines as tumor necrosis factor (TNF-alpha), interferon gamma (IFN-gamma) and interleukin-8 (IL-8). The number of D cells producing somatostatin decreases simultaneously. An increase in gastrin levels could also depend on alkali...
conclusions: vegetables are a new source of h. pylori and accurate washing of vegetables improves such contaminations. results: the results showed that 44 of 460 samples (9.56%) were positive for h. pylori using the culture method. the polymerase chain reaction technique showed that 50 of 460 samples (10.86%) were positive for h. pylori. un-washed leek, traditional salad, un-washed basil and un...
