BACKGROUND Polymorphisms in the immune related genes are important in the clinical outcome of Helicobacter pylori infection. Myeloperoxidase -463 G/A polymorphism has been shown to reduce enzyme expression and activity. OBJECTIVE the aim of the present study is to investigate the association of myeloperoxidase G-463A polymorphism with clinical outcome of Helicobacter pylori infection. METHO...
AIM This study was carried out to assess the prevalence of Helicobacter pylori infection in various ABO blood groups of people of Kashmir. METHOD The study comprised 80 individuals - 50 peptic ulcer patients (whose disease was diagnosed by endoscopy) and 30 asymptomatic volunteers. Every subject's blood group and Rhesus status was determined by standard serological tests. Helicobacter pylori ...
Several infectious agents are considered to be causes of cancer in human, mainly hepatitis B and C viruses, high-risk human pailloma viruses, Helicobacter pylori, Clonorchis sinensis, and Opisthorchis viverrini. Here we described the evident research and the association between Helicobacter spp. and biliary tract cancer particularly cholangiocarcinoma (CCA). Global epidemiological studies have ...
Gastric ulcerations in dolphins have been reported for decades. Some of these lesions were associated with parasitic infections. However, cases of nonparasitic gastric ulcers with no clearly defined etiology also have been reported in wild and captive dolphins. Considerable speculation exists as to whether dolphins have Helicobacter-associated gastritis and peptic ulcer disease. The stomachs of...
Both infection with Helicobacter pylori and alcohol abuse have been associated with low vitamin B12 serum levels. The interaction between both risk factors is unknown. The aim of this study was to determine whether Helicobacter pylori infection is associated with low vitamin B12 levels in alcohol dependent patients. Blood samples were obtained from adult alcohol dependent patients undergoing de...
In dogs Helicobacter spp. are found in all gastric regions usually localized in the surface mucus, gastric glands and parietal cells. The aim of this study was to detail the distribution of Helicobacter spp. in the fundic mucosa of asymptomatic Beagle dogs and their intracellular localization within parietal cells, in order to evaluate species-specific pathogenetic effects on gastric cells. The...
Introduction: Hyperemesis gravidarum (HG) is a relatively common problem. Despite its obvious effect on quality of life in pregnancy, it can lead to dangerous complications. This study was conducted to evaluate the hypothesis that there is meaningful association between hyperemesis gravidarum and gastric infection with Helicobacter pylori. Methods: This is a prospective case-control study in ...
Background: Due to the high rate of Helicobacter pylori infection in our country and its treatment failure, and also because of the high prevalence of antibiotic resistance of this bacterium, evaluating causes of Helicobacter pylori resistance to metronidazole and its effect on the therapeutic course is necessary. Materials and methods: A biopsy sample was obtained from 275 suspected patients r...
Helicobacter felis, Helicobacter bizzozeronii, and Helicobacter salomonis are frequently found in the gastric mucous membrane of dogs and cats. These large spiral organisms are phylogenetically highly related to each other. Their fastidious nature makes it difficult to cultivate them in vitro, hampering traditional identification methods. We describe here a multiplex PCR test based on the tRNA ...
Helicobacter pylori infection, the most common chronic bacterial infection in the world, and an important cause of gastrointestinal disorders, may be involved in the pathogenesis of some extra-gastrointestinal disturbances, as well as an increase in blood levels of certain inflammatory markers. Anti-bacterial activity against Helicobacter pylori and anti-inflammatory properties of omega-3 fatty...
