Objective: Differences in blood group antigen expression may increase or decrease the sensitivity of the host to many infections. Our aim in this study is to examine the relationship between ABO and Rh blood groups of COVID-19 patients and their mortality.
Material and Method: This retrospective observational study was conducted with patients who were diagnosed with COVID-19 in the emergency department of a tertiary hospital between May 1, 2020, and November 1, 2020. Patients who had a positive COVID-19 RT-PCR test and had blood group information in the HIMS database were included in the study. Blood groups, age, and gender information of the patients who included in the study were recorded on a form.
Results: The population of this study consists of 356 patients, of which 171 were women and 185 were men. There were 94 people in the O blood group, 185 people in the A blood group, 48 people in the B blood group, 29 people in the AB blood group, 37 people in the Rh-negative blood group, 319 people in the Rh-positive blood group. When the mortality status between blood groups is examined, it was observed that COVID-19 was less mortal in men with O blood group (p= 0.002).
Conclusion: COVID-19 infection is more common in those with the A blood group compared to the other groups. Additionally, we concluded that being in the O blood group is a factor that reduces mortality in men. More studies with a larger sample size are needed to confirm the results of our study.
