How to Predict Risk of Severe COVID-19 According to Blood Types?

  

The use of blood types may help prediction of the risk of individuals with severe COVID-19

In 2 research reports published in the international journal Blood Advances a few days ago, scientists from the University of British Columbia and other institutions found through research that blood type may affect a person. The risk of COVID-19 and the risk of serious diseases caused by it.

 

The COVID-19 patient group, the proportion of patients with blood type O is lower

In the first study, the researchers compared more than 473,000 COVID-19 patients in Denmark with more than 2.2 million general population. The researchers found that in the COVID-19 patient group, the proportion of patients with blood type O is lower, while The proportion of patients with blood type, type B and AB is higher.

 That is to say, compared with individuals with blood type O, individuals with blood type A, B and AB are more likely to develop COVID-19 infection, and the infection rate is in these 3 blood types are similar in people.

 

Blood type A and AB may need to use mechanical ventilation to breathe

In the second study, the researchers included 95 severe COVID-19 patients who were hospitalized in Canada. 

They found that patients with blood type A and AB may need to use mechanical ventilation to breathe, which shows that the risk of lung damage due to COVID-19 infection is higher.

 In addition, many patients with blood type A and AB also need dialysis to treat kidney failure.

 The results of the study show that patients with type A and AB blood have a higher risk of organ dysfunction or organ failure compared to patients with type O and B blood.

A and AB is not longer than that of patients with blood type O and B 

Based on the second study, the researchers also found that the overall hospital stay of patients with blood type A and AB is not longer than that of patients with blood type O and B, but on average, they spend longer in the intensive care unit. 

This means that his condition of COVID-19 may be more serious. Researcher Mypinder Sekhon said that the uniqueness of our research is to focus on the impact of different blood types on the severity of COVID-19 and the severity of the disease after infection.

 In the current study, we have observed lung and kidney damage in patients. In the future, we In-depth research will continue to sort out the effects of serum and COVID-19 on other vital organs.

 

Many survivors are getting rid of the acute phase of COVID-19 infection

Finally, the researchers said that it is especially important that while we continue to suffer from the COVID-19 epidemic, many survivors are getting rid of the acute phase of COVID-19 infection. But we still need to continue to explore the in-depth mechanism of COVID-19 infection in order In the later stage, stratified research can be conducted on patients with long-term effects, so as to improve the treatment and prognosis of COVID-19 patients.
