The association of main blood groups and development of Systemic Lupus Erythematosus and its organ involvements

Abstract

36 (11.7%), p value = 0.034). In RH negative individuals, there was a significant difference in the frequency of the A blood group between SLE patients and the controls (2 (13.3%) vs. 10 (37%), p value = 0.037). There is no difference in the frequency of different BGs between SLE patients and healthy people. Moreover, no significant relation between different organ involvement in Lupus patients and BG was found, except for mucosal ulcers. Therefore, ’blood group cannot be used as a predictor of disease status.
