Health News – Q&A: Study identifies blood type as marker of risk for severe COVID-19 response

Health News –

9Health Specialist Dr. Payal Kohli answered our questions about a brand-new study in The New England Journal of Medication.

DENVER, Colorado– For months now, medical professionals have understood age plays a role in how individuals respond to COVID-19

Health conditions like heart disease and diabetes can likewise affect the seriousness of the infection.

However a brand-new study in the New England Journal of Medication suggests hereditary markers may likewise help determine people who are most at danger for a severe reaction.

We took the study and our concerns to 9Health expert Dr. Payal Kohli.

( Editor’s Note: Questions and responses might have been modified for context and clearness).

9NEWS: How trusted a source is the New England Journal of Medicine?

Dr. Kohli: “The New England Journal of Medicine is rated as the leading medical journal.

Recently, in the last couple of weeks, there was a retraction that took place from a research study published in the New England Journal of Medication. That definitely got a great deal of people concerned but, in basic, their track record for a number of decades has actually been airtight.

What is the basis of the study?

Dr. Kohli: The factor this research study truly came about is we saw there was a remarkable variation in breathing reaction. So, on this end of the spectrum, somebody who gets the infection but has no signs at all and on this end of the spectrum, somebody who gets the infection and has extreme lung swelling and ends up on a ventilator and in the Intensive Care Unit.

Interestingly, what we saw in many parts of Europe is there tended to be clustering in households. That truly led us down to do this Genome-Wide Association research study.

What is a Genome-Wide Association study?

Dr. Kohli: Essentially, a genome-wide association study develops a genetic map of your DNA. So, the researchers took DNA from 2,000 clients with COVID and extreme breathing signs and 2,000 controls. They mapped out their DNA and searched for genetic distinctions that might potentially describe why these 2,000 people didn’t get that sick and these 2,000 individuals did. Then, they determined potentially which genes those differences mapped onto.

What did they discover?

Dr. Kohli: Interestingly, a lot of those genes are involved in the response to COVID. What they discovered was blood group A had a 45%higher threat of having serious breathing signs and blood group O had a 35%lower threat of having serious signs.

A Few Of the other genes they discovered that might be included are genes associated with the lung, genes involved in the inflammatory reaction, and genes associated with the ACE2 receptor which is the doorway the virus uses to enter into the lungs.

How does this improve our understanding of variations in response?

Dr. Kohli: It does not necessarily mean the blood group is causing severe symptoms. It suggests that it’s potentially a hereditary marker of threat. We’re getting a customized risk score based on our genes. If you’re blood group A, you must possibly consider yourself as a higher threat group. Specifically if you have other high-risk markers like age, diabetes, high blood pressure, etc.

For me, it alters the conversation. As you layer more and more threat elements on, you increase the threat.

I desire to be sure to inform individuals who have blood group O, this doesn’t indicate you should take it easy.

How might this data help inform public health decisions?

Dr. Kohli: I believe the study is really crucial because it recommends something different about the host’s action based on genes that really identifies who gets really sick and who does not.

In a perfect world, what I ‘d like to see is some sort of threat rating being established where you take an individual’s age, they’re comorbidities, their genes, their household history, put all of it together in a calculator and truly personalize the risk for who is going to get really ill and who isn’t. I believe that will help notify our decisions about who is safe to take a trip, who is safe to go out to consume, who is safe to join other people? Up until we get a vaccine, we’re going to have to get better about fine-tuning our risk assessment with regard to COVID. It’s not fine to keep all the older individuals locked up forever and it’s not alright to tell the more youthful people that they’re entirely risk-free. I believe we actually need to get more sophisticated in the threat assessment.
