Prevalence of Helicobacter pylori cagA, vacA, iceA, babA2 genotypes in Polish children and adolescents with gastroduodenal disease* Częstość występowania genów wirulecji cagA, vacA, iceA, babA2 wśród szczepów H. pylori izolowanych od dzieci i młodzieży z chorobami przewodu pokarmowego
Infection with Helicobacter pylori is a major cause of chronic gastritis and peptic ulcer disease in children and its consequences in adulthood can lead to serious complications, including in particular the development of gastric cancer. Our aim was to analyze the relationship between the occurrence of selected genes such as cagA, vacA, iceA, and babA2 determining pathogenicity of H. pylori str...
متن کاملPrevalence of Helicobacter pylori vacA, cagA, cagE, iceA, babA2, and oipA genotypes in patients with upper gastrointestinal diseases
BACKGROUND AND OBJECTIVES Helicobacter pylori has been strongly associated with peptic ulcer diseases, chronic gastritis, ulcers, and reported as a risk factor for gastric cancer, too. The vaculating cytotoxin (vacA), the cytotoxin associated genes (cagA), the induced by contact with epithelium factor antigen (iceA gene), blood adhesion binding antigen (babA2), and outer membrane protein oipA h...
متن کاملPrevalence of Helicobacter pylori vacA, cagA and iceA genotypes in Nigerian patients with duodenal ulcer disease.
Distinct virulence factors of Helicobacter pylori have been associated with clinical outcome of the infection; however, considerable variations have been reported from different geographic regions. Data on genotypes of African H. pylori isolates are sparse. The aim of this study was to determine the prevalence of specific genotypes of H. pylori in Nigerian patients with duodenal ulcer and non-u...
متن کاملPrevalence of Helicobacter pylori vacA, cagA, and iceA Genotypes in Cuban Patients with Upper Gastrointestinal Diseases
Virulence factors of Helicobacter pylori can predict the development of different gastroduodenal diseases. There are scarce reports in Cuba about H. pylori isolates genotyping. The aim of the present investigation was to identify allelic variation of the virulence genes vacA, cagA, and iceA in sixty-eight patients diagnosed as H. pylori positive by culture. In seven out of 68 patients, strains ...
متن کاملPrevalence of Helicobacter pylori vacA, cagA and iceA genotypes and correlation with clinical outcome
The aim of this study was to assess the genetic status of cagA, vacA subtype and iceA genotypes of Helicobacter pylori and the relationship with upper gastrointestinal diseases in Northeast China. Gastric biopsies were obtained from 378 patients with upper gastrointestinal diseases and 197 samples were used. The cagA, vacA alleles and iceA genotypes were determined by polymerase chain reaction....
