Evaluation of the Relationship between Blood Group Types and Intrinsic Temperament of Patients with COVID-19 with Disease Severity

Coronaviruses are a subset of coronaviruses that range from the common cold to more severe illnesses. Symptoms of COVID19 begin a few days after becoming infected with the virus, including fever, dry cough, respiratory distress, fatigue, muscle aches, and diarrhea. Given that the virus causes severe symptoms in some patients, even without the underlying disease, it is likely to be related to the individual characteristics of the patients. Therefore, it seems necessary to study internal characteristics such as blood type, temperament or even the genes of patients.
This study was a cross-sectional study in 2020. A total of 100 people were selected from those who had respiratory symptoms and had a positive QQ 19 test. Mood questionnaire was completed for each person. 3 cc of venous blood was taken from patients to evaluate blood group.
In the study of the relationship between sex and disease severity, 42.2% of men were admitted to the ward and 38.9% of women were mostly examined on an outpatient basis, but this difference was not significant.
Compared with blood groups, O-negative blood group had the lowest and A-positive blood group had the highest prevalence. In terms of prevalence of wet and dry temperaments, 29.6% had wet temperament, 43.2% had moderate temperament and 27.2% had dry temperament. Also, in the study of cold and hot temperament, 21% had a cold temperament, 49.4% had a balanced temperament and 29.6% had a warm temperament. There was no significant relationship between cold temperament and disease severity between the three temperament groups. P = 0.21)). Also, there was no significant relationship between wet and dry temperament and disease severity between the 3 groups (P = 0.09).
According to this study, the prevalence of covid19 disease in warm chord temperaments was higher than other blood clusters. Blood group O was less common than other blood groups, which could be helpful in the prognosis of patients.
