Helicobacter pylori (H. pylori) is one of the most common human infections worldwide particularly in the developing countries. It has been established as etiology of chronic gastritis and peptic ulcer disease, gastric adenocarcinoma and mucosal associated lymphoid tissue lymphoma (MALT). During this decade, there have been some reports showing a decline in global prevalence of H. pylori infecti...
Abstract Background and Objective: Helicobacter pylori (H. Pylori) infection is related to chronic gastritis, peptic ulcer, duodenal ulcer and gastric cancer. Thus, identification and treatment of the infection have a considerable importance. The aim of this study was to compare three methods of Histopathology, Culture and Rapid Urease test (RUT) in identification of H. Pylori in gastric bio...
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...
BACKGROUND The role of Helicobacter pylori (H. pylori) in the pathogenesis of coronary artery disease (CAD) is still controversial, and the relation between current H. pylori infection and CAD has not been fully examined. This study evaluated the relation between H. pylori infection as confirmed by gastroduodenoscopic biopsy and CAD. METHODS We determined the presence of H. pylori infections,...
OBJECTIVES/HYPOTHESIS To determine if there is a relationship between Helicobacter pylori colonization in the pharynx mucous membrane and chronic nonspecific pharyngitis. STUDY DESIGN A prospective clinical study. METHODS Seventy patients with chronic pharyngitis and 20 healthy control subjects were examined with polymerase chain reaction (PCR) and culture for H. pylori colonization in the ...
It has been suggested that the prevalence of Helicobacter pylori infection has stabilized in the USA and is decreasing in China. We conducted a systematic literature analysis to test this hypothesis. PubMed and Embase searches were conducted up to 19 January 2015. Trends in the prevalence of H. pylori infection over time were assessed by regression analysis using Microsoft Excel. Overall, 25 Ch...
AIM To explore the association between Helicobacter pylori (H. pylori) infection and obesity/weight gain in a Chinese population. METHODS Our primary outcome was the change in body mass index (BMI). The generalized linear models were used to explore the association between H. pylori infection and the change of BMI, and the logistic regression models were used to explore the association betwee...
Background The pro- and anti-inflammatory cytokines play an important role in the immune response against H. pylori infection. The proinflammatory cytokines of Th17 cells have been suggested to play a major role in H. pylori infection and resulting gastric inflammation. Objective The objective of this study was to compare the expression of selected inflammatory cytokines (IL-10, IL-17, IL-21,...
conclusions about 90% of h. pylori strains potentially contained vaca s2m2 and s1m2 genotypes. infection with h. pylori strain containing the caga gene or the vaca s1m1 and s1m2 genotypes was associated with increased incidence of peptic ulcer disease (pud). objectives the aim of this study was to determine the frequency of two toxins and genotypes of vaca toxin in patients referred to a centra...
BACKGROUND AND AIM The infection of Helicobacter pylori (H. pylori) is acquired in childhood and the prevalence vary greatly in different countries and regions. The study aimed to investigate the characteristics of H. pylori infection among children with gastrointestinal symptoms in Hangzhou, a representative city of eastern China. METHODS A systematic surveillance of H. pylori infection acco...
