(HealthDay) – There is more evidence that blood type may affect a person’s risk of COVID-19 and serious illness from the disease
The results are reported in two studies published on October 14 in the journal Blood Advances
In one case, researchers compared more than 473,000 people in Denmark with COVID-19 to more than 22 million people in the general population
Among patients with COVID-19, there was a lower percentage of people with blood type O and higher percentages of people with types A, B and AB
Results suggest that people with A, B or AB blood may be more likely to be infected with COVID-19 than people with type O blood Infection rates were similar in those with blood types A, B and AB
The other study included 95 critically ill COVID-19 patients hospitalized in Canada Patients with type A or AB blood were more likely to require mechanical ventilation, suggesting they had higher rates of lung damage due to COVID-19
More and more patients with blood type A and AB required dialysis for kidney failure, study added
The results suggest that patients with COVID-19 with blood groups A and AB may have an increased risk of organ dysfunction or failure than those with type O or B blood, researchers say
They also found that while people with blood groups A and AB did not have a longer overall hospital stay than those with types O or B, on average they were in intensive care for longer, this which may indicate more serious COVID-19
« The unique part of our study is our focus on the effect of blood group severity on COVID-19 We observed these lung and kidney damage, and in future studies we will want to highlight the effect of blood group and COVID-19 on other vital organs, « said study author Dr Mypinder Sekhon, clinical instructor in the Division of Critical Care Medicine at the University of Colombia. British in Vancouver, Canada
« Of particular importance as we continue to navigate the pandemic, we now have a wide range of survivors emerging from the acute portion of COVID-19, but we need to explore the mechanisms by which to risk stratifying those who have effects ”, he added in a press release
