Abstract

Purpose: The ABO blood type system is crucial for human blood transfusions. However, the relationships between ABO blood groups and diseases in the digestive system and vein have not been elucidated. We investigated the relationships between ABO blood groups and diseases in the digestive system and vein in this study.

Patients and methods: A retrospective study on a Chinese population, including 1432 Crohn's disease (CD), 416 ulcerative colitis (UC), 1140 stomach cancer (SC), 841 colorectal cancer (CRC), 384 pancreatic cancer (PC), 520 liver cancer (LC), and 563 venous thrombosis (VT) patients, was performed. Furthermore, 896 healthy subjects were enrolled as normal controls (NC) in this study. The demographic characteristics of patients and NC were compared using the unpaired t-test and χ2 test. Multivariate logistic regression model was used to evaluate the association between ABO blood groups and CD and VT.

Results: ABO blood groups distributions in UC, SC, CRC, PC, and LC patients did not differ from that of NC, but CD and VT patients had significant difference of ABO blood group distribution from that of NC (p = 0.015 and p = 0.002, respectively). Patients with CD and VT had considerably lower rates of type O blood (p = 0.011 and p = 0.001, respectively) and significantly higher rates of type AB blood (p = 0.013 and p = 0.022, respectively) than those with NC. Multivariate logistic regression analysis showed the association of CD and VT with non-O blood types was still significant with a higher risk than with blood group O after adjusting for age and gender (OR = 1.355, 95% CI = 1.100-1.670, p = 0.004 and OR = 1.465, 95% CI = 1.131-1.903, p = 0.004, respectively).

Conclusion: ABO blood groups distributions in CD and VT patients significantly differed from that of NC. Non-O blood group could be a new predictor for CD and VT.

Keywords: ABO blood groups; CD; VT; non-O blood group.
