Helicobacter pylori and Its Virulence Factors' Effect on Serum Oxidative DNA Damages in Adults With Dyspepsia

Helicobacter Pylori infection is a common gastrointestinal infection that can cause pathological effects, increase oxidative stress and induce an inflammatory response in gastric mucosa. Inflammatory aspects may prompt the production of radical oxygen substance (ROS) which may damage cells and relea...

description Helicobacter Pylori infection is a common gastrointestinal infection that can cause pathological effects, increase oxidative stress and induce an inflammatory response in gastric mucosa. Inflammatory aspects may prompt the production of radical oxygen substance (ROS) which may damage cells and release 8-hydroxydyoxyguanosine (8-OHdG) to serum. In this study, we evaluate the prevalence of H. pylori virulence factors and the association between serum level of 8-OHdG, H. pylori infection, and its various virulence factors. The presence of H. pylori and prevalence of cagA, babA and oipA genes in samples were determined by rapid urease test (RUT), histopathological exam (HE) and polymerase chain reaction (PCR) and oxidative DNA damage situation were assessed by using serum level of 8-OHdG. There was not any direct relation between H. pylori negative and H. pylori oipA+specimens by 8-OHdG serum level (P>0.05). In all clinical observations, the presence of cagA and oipA genes was common. There was a statistical relationship between the presence of cagA, babA factors, and high serum level of 8-OHdG (P<0.05). The presence of cagA and babA virulence factors may be associated with increased serum 8-OHdG in dyspeptic patients and may induce the damage to gastric cells.
