The Novel Coronavirus SARS-CoV-2 Vulnerability Association with ABO/Rh Blood Types

Abstract

<span style="color: #ffffff;"><strong><span style="background-color: #2c3e50;">Background & Objective:</span></strong></span> Coronavirus disease 2019 (COVID-19) is the most recent emerging viral disease. Defining the epidemiological aspects and factors influencing the susceptibility of the patients to COVID-19 has been an ongoing struggle. In the present study, we have investigated the connection between ABO histo-blood group phenotypes and the COVID-19.<br /> <span style="color: #ffffff;"><strong><span style="background-color: #2c3e50;">Methods:</span></strong><span style="background-color: #2c3e50;"> </span></span>This study was conducted on 397 patients with confirmed diagnoses of COVID-19 admitted to our center. Also, 500 individuals were selected to form the controls, all of whom had been disclosed to the same medical center in June 2019, before the onset of the outbreak.<br /> <span style="color: #ffffff;"><strong><span style="background-color: #2c3e50;">Results:</span></strong><span style="background-color: #2c3e50;"> </span></span>Our results demonstrated ABO histo-blood phenotypes are correlated with patients' susceptibility to the infection<strong>. </strong>A higher rate of infection was observed among patients with the AB histo-blood group, while patients with the O histo-blood group have shown a lower rate of infection. The Rh blood group phenotype was not statistically significant in determining a patient's vulnerability.<br /> <span style="color: #ffffff;"><strong><span style="background-color: #2c3e50;">Conclusion:</span></strong></span> Similar to several previous studies about other viral diseases' association with ABO histo-blood groups, we have concluded that an individual's ABO histo-blood group phenotype and his/her susceptibility to COVID-19 are indeed connected. So far, only one research has been conducted about this association. Interestingly, while we observed a decreased vulnerability to the disease among patients with an O histo-blood group, we have reached discordant results regarding the increased susceptibility among individuals with an AB histo-blood group, unlike A histo-blood group in the previous study.
