Blood Adv: Use blood type or hopefully help predict an individual's risk of contracting severe COVID-19

21, 2020 // -- In two recent studies published in the international journal Blood Advances, scientists from the University of British Columbia and other institutions have found that blood type may affect a person's risk of COVID-19 and the resulting serious disease.
in the first study, researchers compared more than 473,000 COVID-19 patients in Denmark with more than 2.2 million in the general population, and found that the proportion of patients with type O blood was lower in the COVID-19 patient population. , while the proportion of patients with type A, B and AB is higher, that is, individuals with type A, B and type AB blood are more likely to develop COVID-19 infection than individuals with type O blood, and the infection rate is similar among the three blood types.
in a second study, researchers included 95 patients hospitalized in Canada with severe COVID-19, and found that patients with type A and AB blood may be more likely to need mechanical ventilation to breathe, suggesting a higher risk of lung damage from COVID-19 infections.
, many patients with type A and AB blood need dialysis to treat kidney failure.
study showed that patients with type A and AB blood had a higher risk of organ abnormalities or organ failure than patients with type O and type B blood.
Based on the second study, the researchers also found that patients with type A and AB blood spent no more time in hospital than 2006 and type B, but on average spent longer in intensive care units, meaning they were likely to be more severely infected with COVID-19. 'What's unique about our study is that we look at the effects of different blood types on individuals with COVID-19 and the severity of the disease after infection,' said Mypinder Sekhon, a
researcher. 'In the current study, we have observed lung and kidney damage in patients, and we will continue to study the effects of haemorrhagic clearing and COVID-19 on other vital organs in the future.'
Finally, the researchers say it's especially important that many survivors are emerging from the acute phase of COVID-19 infection as we continue to suffer from the new coronary epidemic, but we still need to continue to explore the in-depth mechanisms of COVID-19 infection so that strataging studies of patients with long-term effects can be conducted at a later stage to improve treatment and prognosis in PATIENTs with COVID-19.
