Study the Relationship between Helicobacter pylori Infection and ABO Blood Groups and Rh Status

Abstract

AbstractThis paper was aimed to investigate the association between the ABO blood groups and H.pylori infection and to determine how much endoscopic findings are predict for the presence ofactive H. pylori infection. One hundred and twenty dyspeptic patients (as diagnosed by endoscopyand confirmed by histopathology) and sixty apparently healthy individuals were enrolled in thisstudy. All subjects were underwent ABO blood grouping and Rhesus (Rh) systems determination.The results reveals higher frequency present of blood type O and the lowest frequency present ofblood types A and AB among H. pylori patients compared to positive control group. The endoscopicfindings showed low sensitivity in the diagnosis of H. pylori associated gastritis. In conclusion, thereare considerable positive relationship between H. pylori infection and blood type O.
