The Relation between Helicobacter Pylori Infection and Abo Blood Group and Rhesus Factor

Article excerpt

Background: Helicobacter pylori infection is currently endemic worldwide health problem. The infection causes chronic gas- tritis, peptic ulcer, and gastric adenocarcinoma. It is clear that blood group (BG) antigens are important to the development of intestinal disorders. This study determines the relationship between H.pylori and ABO blood group, Rh factor and bacte- rial infection.

Methods: The study included 160 patients (18-80 years) with dyspepsia symptoms referred to Hajar hospital in Shahrekord. Demographic data were collected. Patients were checked by 16sRNA gene polymerase chain reaction for H. pylori. Severity of H.pylori infection was graded according to the number of HP bacteria counted in light microscopy by (x1000 magnified). Blood groups were detected by a standard hemagglutination test.

Results: We observed that 61.87% of patients (99 of 160) were positive for H. pylori, and 38.13% were negative (61of 160). In the positive patients, 37.74% were male and 62.26% were female; also in the negative patients, 50.05% were male and 49.95% were female. The frequency of the ABO blood groups among positive patients was (A = 33.05%, B = 20.23%, AB = 6.06%, O = 40.66%) and was (A = 32.32%, B = 25.51%, AB = 8.84%, O = 33.33%) in negatives. HP was found in 20/40 Rh- and in 77/120 Rh+ patients without statistical difference (P>0. …
