Background: At least half the world’s population is colonized the stomach by Helicobacter pylori (H. pylori) which are a key constituent of the human microbiome. The aim of this study was to investigate the association of cardiometabolic risk factors with H. pylori infection in Iranian adolescents. Materials and Methods: The current study was conducted along with the third survey of a national ...

Objective: To determine the prevalence of H. pylori infection in patients with idiopathic chronic urticaria (ICU) and to see if eradication of the bacterium affects the course of the urticaria. Patients and Methods: One hundred patients with idiopathic chronic urticaria and 43 healthy subjects (matched for age and sex) underwent serological testing for H. pylori infection. All patients with idi...

Helicobacter pylori has been recently detected in the oral cavity and oropharynx. However, the role it plays in oral and oropharyngeal pathogenesis remains unclear. The virulence of H. pylori strains can be distinguished according to the virulence factors genes carried. Our research has been focused on realtime PCR analysis of cagA and vacA genes of H. py...

A 32−year−old man in whom a perforated duodenal ulcer had been surgically closed with laparotomy 3 weeks previously pre− sented to our emergency department with symptoms of persistent epigastralgia and fever. At esophagogastroduodenoscopy, abundant whitish pus was noted stream− ing from the pylorus into the gastric an− trum (Figure 1). The source of the pus was a large duodenal ulcer in the de−...

Helicobacter pylori (H. pylori) is an ancient and persistent inhabitant of the human stomach that is closely linked to the development of gastric cancer (GC). . Emerging evidence suggests that H. pylori strain interactions with gastric epithelial cells subvert the best- characterized p53 tumour suppressor pathway. A high prevalence of p53 mutations is related to H. pylori infection. H. pylori a...

itp is an autoimmune blood disorder in which platelet destruction is mediated by anti-platelet antibodies. the mechanisms of anti-platelet antibodies development are still a little known. the rate of some bacterial or viral agents in cause of itp is well known. recently, some study proposed that h pylori infection may be associated with itp and h pylori eradication can improves platelet counts ...

Helicobacter pylori antibodies were measured over 24 months in American Indian and Alaska Native persons who cleared their infections. Two months after treatment, 82% of H. pylori-negative persons remained seropositive. While there were declines in H. pylori antibodies for 12 months, after 24 months 71% of persons remained seropositive.

The urea breath test UBT C13,14 is a good rapid diagnostic procedure used to identify stomach infections by H. pylori. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide. Urea breath tests are recommended in leading society guidelines as a preferred non-invasive choice for detecting H. pylori of stomach before and after treatment with diagnostic efficacy at ...

INTRODUCTION. Helicobacter pylori infection can be diagnosed by biopsy-based or noninvasive methods. Our aim was to identify H pylori-positive patients on hemodialysis by the noninvasive method of H pylori stool antigen (HPSA) and investigate its diagnostic accuracy for assessment of the eradication of infection after treatment in comparison with urea breath test (UBT). MATERIALS AND METHODS. S...

Symbiotic, parasitic, and commensal relationships have precise definitions in biology, but often the nature of the relationship between two organisms is not clear-cut and fluctuates over time. This Microbiology Select highlights recent studies that demonstrate how communication between the host and its microbial inhabitants largely determines whether their interaction is beneficial, hurtful, or...
