Blood type does not affect our daily life much. In fact, many people do not even know if they belong to group A, B, AB or 0. But this seemingly insignificant detail may be an important factor in the most talked about event of the year: the coronavirus pandemic. .
A new study in Blood Advances supports what researchers have long observed: People with blood type A have a higher risk for Covid-19, while people with blood type 0 appear to be more protected from it, according to a range of growing studies.
Researchers in China were the first to launch the idea in March, whose findings echoed a month later. Even the DNA testing company 23andMe surveyed customers and found that among the 750,000 people (by far the largest group of people studied) who had been diagnosed and hospitalized for Covid-19, those with blood type 0 were the most protected.
Then, a study published in the New England Journal of Medicine confirmed this approach through a peer-reviewed study: People with blood type A were 45% more likely to become infected with Covid-19 than others, while people with group 0 had less likely to become infected.
"I do not think having group A or B is a problem. "It's just that those with group 0 are more protected," said Mark Udden, a professor of hematology and oncology at Baylor College of Medicine in Houston.
Are people with blood type A more likely to die from Covid-19?
People with blood type A appear to be more likely to become infected with Covid-19, but this does not mean that they have a higher chance of dying. A Columbia University study found that there is no link between blood type and death.
What is different about blood type 0?
There are several theories. "The most basic idea is that blood type can affect a person's ability to fight the virus," says David Aronoff, director of infectious diseases at Vanderbilt University Medical Center in Nashville. May affect the strength of the immune system or the inflammatory response to infection.
Another doctor told NEJM: "If you have group 0, you naturally have antibodies against groups A and B. These type A antibodies can make it difficult for SARS-CoV-2 to bind to its receptor in the blood of group 0. and multiply in the body. ” There is also talk of a possible protective element in group 0 blood.
So if you have blood type 0, are you protected?
Jo. Të gjitha studimet e deritanishme kanë marrë në shqyrtim vetëm rastet simptomatike, gjë që do të thotë se është e paqartë se çfarë mund të ndodhë me organizmin e personave asimptomatikë.
A është grupi i gjakut faktori kryesor i rrezikut ndaj Covid-19?
Jo. Grupi i gjakut është një faktor, por jo i vetmi. Madje konsiderohet një faktor jo fort i rëndësishëm.
Përfundime
Njerëzit me grup gjaku 0 janë pak më të mbrojtur nga koronavirusi, ndërsa ata me grupin A më të rrezikur. Por, mesa dihet, të gjithë janë të rrezikuar të marrin virusin, në rast se nuk respektojnë masat mbrotjëse. Po kështu, nuk ka rëndësi grupi i gjakut, një asimptomatik ka potencialin të infektojë të tjerët.
