Study the relationship between helicobacter pylori infection and ABO blood groups and Rh status

Abstract EN

This 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 of active H.

pylori infection.

One hundred and twenty dyspeptic patients (as diagnosed by endoscopy and confirmed by histopathology) and sixty apparently healthy individuals were enrolled in this study.

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 of blood types A and AB among H.

pylori patients compared to positive control group.

The endoscopic findings showed low sensitivity in the diagnosis of H.

pylori associated gastritis.

In conclusion, there are considerable positive relationship between H.

pylori infection and blood type O.
