Covid-19: your blood type can predict your risk of suffering a serious form
What if your blood type was important against Covid-19? Studies are increasing to confirm a possible correlation. Like two investigations published on Wednesday October 14 in the magazine Blood Advances.
Two new studies confirm that patients with blood group O have a lower risk than others of contracting a severe form of the disease.
In the first study, scientists compared more than 473,000 people living in Denmark with Covid-19 with more than 2.2 million people in the general population. Thus, they found that among the patients there was a lower percentage of people belonging to blood group O and a higher percentage of people in groups A, B and AB. Findings that lead researchers to believe that people in these three blood groups are more likely to be infected with the virus than those in group O. Infection rates were similar in people in groups A, B, and AB.
The second study included 95 patients with a severe form of Covid-19 hospitalized in Canada. The researchers observed that patients with blood group A or AB were more likely to require mechanical ventilation, suggesting that they had higher rates of lung damage from the new coronavirus than other patients. Additionally, more patients in these two groups required dialysis for kidney failure.
More time in intensive care
The results suggest that Covid-19 patients with blood groups A and AB may have a higher risk of dysfunctions than those with blood types O or B, according to the researchers. Going even further, they also found that people in groups A and AB spent more time in intensive care than other patients. These are all signs that these patients did have a more severe form of the virus, although they generally did not spend more time in hospital than the others.
"The unique part of our study is that we are focusing on the effect of blood group on the severity of Covid-19. We have looked at these lung and kidney damage, and in future studies we will seek to highlight the" effect of blood group and Covid-19 in other vital organs, "said study author Dr. Mypinder Sekhon, clinical instructor in the Division of Critical Care Medicine at the University of British Columbia in Vancouver, Canada. He added:" We now have a wide range of survivors who They come out of the acute part of Covid-19, but we need to explore the mechanisms by which some develop long-term effects. "
