Özet

Aim: Currently, it is still a matter of debate whether a particular blood types is associated with an increased risk of severe acuterespiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In the present study, we aimed to evaluate the relationship between theABO blood group types and mortality in patients hospitalized with the diagnosis of Coronavirus disease-2019 (COVID-19).Methods: This cross-sectional study included 427 patients diagnosed with COVID-19 between March 2020 and June 2020. SARS-CoV-2ribonucleic acid was investigated in the naso/oropharyngeal swab samples of the patients by polymerase chain reaction. The bloodgroup types, clinical and demographic data of the cases were obtained from the hospital automation system and patient files.Results: The age range of the patients was between 18 and 96, and 53.4% (228/427) of them were male. The ABO blood groupdistribution was 47.1% A, 29.5% O, 15.9% B, 7.5% AB. The overall mortality rate of COVID-19 cases was 16.9%. COVID-19 mortalityrisks were not significant in any of the ABO blood group types.Conclusion: We did not find a significant relationship between blood group types and mortality in patients who were hospitalized witha diagnosis of COVID-19 and received treatment and follow-up
