Covid-19 infected patients with blood groups 0 and B spent less time in intensive care than those with groups A and AB. Also, they were less likely to need a respirator and less likely to have kidney problems, new research has shown.
Both studies were published in the journal Blood advances. In one, 95 critically ill patients were monitored in Vancouver hospitals between February and April.
It was found that patients with blood groups 0 and B spent, on average, 4.5 days less in intensive care than those in group A or AB, who spent an average of 13.5 days in intensive care.
The researchers did not determine the connection between blood type and length of hospital stay. However, 61 percent of those with blood groups 0 and B wore a respirator, compared with 84 percent of those with groups A and AB.
Also, patients with blood types A and AB needed dialysis more often, a procedure that helps the kidneys filter toxins from the blood.
“Patients with these two blood groups may have a higher chance of organ failure due to kovid-19 than those with blood groups 0 and B,” the authors concluded.
This study is in line with an earlier study from June, which found that group 0 patients in Spain and Italy were 50 percent less likely to develop a more severe form of infection compared to other groups.
People with blood group 0 are more likely to get kovid-19
Another new study found that people with blood type 0 are less likely to get sick compared to people in other groups.
The team analyzed data from almost half a million people tested in Denmark from the end of February to the end of July. Of the 4,600 who tested positive for kovid-19, 38.4 percent had blood group 0.
This is less than the proportion of blood group 0 in Denmark’s total population: 41.7 percent, so the researchers concluded that people with blood group had a reduced susceptibility to infection.
