Background:Only a few Helicobacter pylori-infected individuals develop severe gastric diseases and virulence factors of H. pyloriappear to be involved in such clinical outcomes. Duodenal ulcer promoting gene A (dupA) is a novel virulence factor ofHelicobacter pylori that is associated with duodenal ulcer development and reduced risk for gastric carcinoma in some populations. The aims of the present study were to determine the presence ofdupA gene and evaluate the association amongdupA and other virulence factors includingcagA and vacA in Brazilian patients. Gastric biopsies were obtained from 205 dyspeptic patients (100 children and 105 adults). DNA was extracted and analyzed for the presence of H. pylori and its virulence factors using the polymerase...

Venom. Anim. Toxins incl. Trop. Dis. Caleman Neto,Agostinho; Rasmussen,Lucas T; Labio,Roger W de; Queiroz,Valdeir F de; Smith,Marília de AC; Viani,Gustavo A; Payão,Spencer LM. Background : Epidemiological investigations have indicated thatHelicobacter pyloriinduces inflammation in the gastric mucosa regulated by several interleukins. The genesIL1BandIL8are suggested as key factors in determining the risk of gastritis. The aim of this paper was to evaluate the association of gene polymorphism of interleukin-1 and interleukin-8 with chronic gastrits inH. pyloriinfected patients. A total of 60 patients underwent endoscopic procedure. Biopsy samples were collected for urease test, histopathological and molecular exams. The DNA of theses samples was extracted for detection ofH. pyloriand analysis of the genes mentioned above. Patients with gastritis had a higher frequency ofH. pylori-positive samples.Results : H. pyloriwas detected...

Abstract Background Tumor necrosis factor plays a critical role in the pathogenesis of gastric diseases such as gastric cancer, and an abnormal inflammatory response has frequently been observed in dyspeptic patients. Helicobacter pylori infection can induce a gastric mucosal inflammatory response that may be influenced by -308 (G > A) polymorphisms and gene expression of theTNF-α gene. Methods One hundred and thirty-four gastric biopsy samples were collected from patients of both genders (61♂ and 73♀, mean age 40.3 ± 24.2 years) with gastric symptoms. The -308 (G > A) polymorphism of TNF-α was characterized using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). The expression level was measured using real-time... Tipo: Info:eu-repo/semantics/article Palavras-chave: H. pylori; TNF-α Gene expression; Gastric cancer cagA.
