SCIENTISTS HAVE STUDIED IT… DOES THE BLOOD TYPE AFFECT COVID-19?
The world is trying to combat the disease with the covid-19 vaccine. For this purpose, both vaccination and various vaccines continue to be developed, while studies are also being conducted on the relationship between Covid-19 and blood groups. So, is there a link between Covid-19 and blood groups?
A study in the journal Blood Advances concluded that those with blood type A may be more likely to develop Covid. In a study that examined the relationship between blood type and Covid-19, it was determined that coronavirus affects Group A found in respiratory cells. In addition, previous studies have also found that group a can develop the disease with severe symptoms.
Another study on the subject showed that people with 0 blood types were more resistant to Covid and experienced the disease more mildly. There are many studies of the connection between different blood groups with Covid. Internal Medicine and hematology specialist Prof. Dr. we asked.

REGARDLESS OF BLOOD TYPE, ALL YOU HAVE TO DO IS FOLLOW THE PRECAUTIONS
1. How do you evaluate studies of the course of coronavirus of the blood type?
It is much debated that the risk of contracting Covid-19 from the early days of the outbreak and the course of the disease may be related to blood type. The first claims came out of China at the beginning of the outbreak. In many different studies throughout the process, both the incidence of Covid-19 and the risk of severe disease were shown to increase in people with blood Group A. If we can better understand how the virus communicates with blood groups, it could help us find new drugs or ways to prevent the virus.
On the other hand, we should note that the differences found in research are not obvious enough. Those with a blood type of 0 are not at risk, Covid-19 is not caught or very slightly overcome, we can not say. Those with 0 blood types also have to comply with the precautions and be protected. Those with A or AB blood type also need not worry. Whatever your blood type, all you have to do is follow the precautions.
In fact, the relationship between blood groups and infections has been debated for many years. It has been shown before that blood groups can be important for viral, bacterial and parasitic infections. For example, in the stomach where everyone always hears his name, H. 0 blood type is considered a risk factor for pylori infection. The structures (antigens) that make up the blood group can act as receptors for some microorganisms.
2. Do your blood types have any effect on catching Covid? What are the reasons behind this?
The study, conducted by the fairly well-known genetics and biotechnology company and Me in America, also examined Covid-19 and blood groups. The study included 750,000 patients diagnosed with Covid and hospitalized. Although having a blood type of 0 is a low rate, according to the study results, it seems to protect it from Covid-19. In blood group A, the risk of contracting Covid-19 was higher.
The study conducted in Denmark is quite extensive, with 38% of the entire Danish population included in this study. The study showed that people with 0 blood groups had a 13% lower risk of contracting COVID-19. In terms of the course of the disease and the risk of death, the effect of the blood type was not shown.
The study, published in the past weeks at the beginning of March, is very important for us to understand the mechanism. In the study, it was shown that the structures (antigens) that determine the blood group are also found in the cells that surround the respiratory tract and the inner surface of the lungs. And it has been shown that the Covid-19 virus binding site to cells binds quite well to blood group A antigens, especially found in the respiratory tract. It was also claimed that group A could catch the infection more often.
3. How does blood type affect the course of the disease?
Here we come across two different theories. First, those with 0 blood groups have fewer clotting factors, and therefore covid-19-related clot problems are less common. As is known, clots are one of the most important causes of death in coronavirus disease and can cause damage to many organs such as the lungs, heart, brain and kidney.
In the second theory, it is believed that changes in the genetic sequence in which the blood group is encoded may be associated with excessive immune response and increased IL-6 cytokine release. The answer to many of the problems associated with Covid-19 is hidden in our genetic structure and immune system, and these questions are still waiting to be answered clearly.
4. Which group is most at risk of disease?
The genetic sequence of about 1600 patients from Spain and Italy was studied and compared with the control group. It was shown that the risk of severe monitoring of Covid-19 (oxygen/ventilator requirement) increased by 50% in blood group A patients, and that the risk was 35% lower in blood group 0. In other words, Blood Group A patients had a higher risk of severe disease, while blood group 0 had a lower risk.
Another study published by Canadians examined 95 severe and critical coronavirus patients and showed that those with blood type A or AB were more likely to need mechanical ventilation. At the same time, those with A or AB blood type had a longer stay in intensive care. In short, in the A or AB blood group, the disease was more severe in terms of intensive care and intubation.
5. Is there variability in intubation and stay in intensive care?
A study published by Canadians examined 95 severe and critical Covid-19 patients and showed that those with blood type A or AB were more likely to need mechanical ventilation. In Group A and AB, the intubation rate is 84%, and in Group o and B, it is 61%. At the same time, those with A or AB blood type had a longer stay in intensive care. Patients with A & AB blood group remained in intensive care for 13.5 days, while in 0 or B blood group, this period was 9 days. In short, in Group A or AB, the disease was more severe in terms of intensive care and intubation.
6. Does positive and negative blood type affect the course of the disease?
In the published studies, no clear data was shown that RH positivity or negativity in the blood group affects the course of the disease or the frequency of Capture. There is no significant difference between the positive and negative groups.
