Blood Group Type

The association of ABO blood group types with the COVID-19 disease has been confirmed by several studies, with the blood group A-type patients being more susceptible and prone to more severe clinical course of disease. Similarly, some authors explored the association of ABO-types and the levels of anti-SARS-CoV-2 antibodies in convalescents. The recent reports mostly support a theory that non-O blood group convalescents present with higher levels of anti-SARS-CoV-2 antibodies. Since these findings were based on small convalescent cohorts, we quantified the anti-SARS-CoV-2 antibodiy levels in four larger cohorts of total 3185 convalescent plasma donors with three commercial serological tests and one standard neutralizing antibody test. The majority of donors had undergone a mild form of disease and the median time of sampling was 66 days after the onset of COVID-19 symptoms. None of the antibody quantitation methods showed an association of the ABO blood group types with the level of anti-SARS-CoV-2 antibodies. The same result is evident in the group of vaccinated individuals (n=370) as well as in the groups stratified into three post-COVID-19 periods (0-60, 60-120, and 120-180 days). In conclusion we can state that the ABO blood group type does not influence the level of SARS-CoV-2 antibody response in COVID-19 convalescent plasma donors.

In a prospective study of maternal genital colonization with group B streptococci (GBS) at the time of delivery, epidemiological data, including blood type (ABO group), were recorded for the 1,062 patients studied. Blood type B was found in a statistically significant higher proportion of patients colonized with CBS (28%) compared with the total population (16.4%) (P < .005, x2 = 8.43). Women with blood type B were twice as likely to be colonized as those with types 0 or A. Hypotheses to explain this observation include the possibilities that GBS possess a B-like antigen, rendering parturients who lack anti-B antibody at increased risk for GBS colonization, or that GBS possess a receptor site for B surface antigens. One may speculate that a mutation toward an affinity for the human ABO blood group type B accounts for the advent of the group B Streptococcus as a significant perinatal pathogen.
