Abstract:
Objective To clarify the relationship between ABO blood group and the development of duodenal ulcer(DU)in aspects of gastric acia and Hp infection.Methods The blood group of ABO was determined in 80 patients who were diagnosed as DU and received 24-hour gastric pH monitoring between 1995 and 2003.These results were compared with the expected frequency in the 1061 healthy controls in Beijing.The prevalence Helicobacter pylori (Hp) infection rate was determined by rapid urinase test,biopsy and 13C breath test.Results Blood type O was present in 56.3% of the patients with DU,which was significantly higher than the expected rate (28.7%) in healthy population (? 2=26.69,P0.05).Conclusion Blood group O doesn’t cause the disease by affecting Hp infection rate or stronger gastric acid secretion,it maybe another independent risk factor for DU.The onset age in blood group O is not different from that in other types.The mechanism needs to be explored.
