Keywords: Covid-19, ABO, Rh, Blood groups
We aimed to investigate whether there is a predisposition to COVID-19 with ABO and Rh blood group systems. This study was a retrospective study that investigate the patients admitted to our hospital between March 16 -May 20 due to Covid-19 pandemic and conducted with data revealed from the hospital Information Management System A total of 392 patients were included in this study, including 227 PCR test positive patients with blood group information in the system and 165 possible patients with CT findings in favor of Covid-19. Data from a blood group study conducted with 127091 people in our province in 2019 were used as a control group. In our study, a significant increase was observed in the blood group A in patients diagnosed with Covid-19, and a decrease was found in the blood groups B, AB and especially O. However, statistical analysis showed no significant difference between Covid-19 patients and healthy individuals in terms of ABO blood group system. When analyzed in terms of Rh blood group system, it was found that Rh positivity was statistically significantly higher in patients with Covid-19 (p= 0.000). Our study suggests that the Rh (–) blood group is protective and the Rh (+) blood group is predisposed to Covid 19 significantly. We think that it is valuable because it is the first study to reveal the relationship between Covid-19 and blood type in our country and the only one to reveal the relationship between Covid-19 and Rh (+) in the world literature.
