BACKGROUND: SARS-CoV-2 infection is clinically very heterogeneous, varying from
asymptomatic to severe clinical conditions with a fatal outcome. Some studies
suggests that the ABO blood group could be a biological marker of susceptibility
for the development of the disease. PATIENTS AND METHODS: We collected data from
patients admitted with COVID-19 infection who had ABO blood group recorded, and
analyzed the incidence by groups, compared with the global population in Navarre,
as well as their main complications and evolution. RESULTS: Group O was
proportionally less represented in the hospitalized patients with respect to the
global population, although the difference was not statistically significant.
Group B had significantly higher rates of thrombotic complications and required
more admissions in intensive care units. CONCLUSION: The study suggests a lower
susceptibility to infection in group O and a higher risk of complications in
group B. Studies with a larger sample size are required in order to obtain
significant results.
