- Researchers studying the immune responses of coronavirus patients will eventually be able to explain why some people develop life-threatening COVID-19 complications.
- COVID Human Genetic Efforts detailed the successful findings on interferon issues that endangered lives during COVID-19.
- Scientists have found that some people have tontibodies to interferon, while others may suffer from undiagnosed genetic conditions that affect interferon efficacy.
Then whether it’s a novel coronavirus or a different infectious disease that can lead to life-threatening complications, vaccines are just one part of the solution. The biggest news of the week was the incredible announcement by Pfizer and Bioentech that their drug has been found to be more than 90% effective against pathogens so far. The final results of the Phase 3 trial may change and that effectiveness figure may end up being low, but initially it is an excellent place.
Preventing infection and severe COVID-19 cases will not be enough, unless thousands of people around the world die due to complications. Vaccines will take time to meet demand, and more people will be infected in the meantime. The world still needs effective therapies that can further reduce the risk of death until most of the world’s immune system is up, and the risk of transmission is significantly reduced. The pair of studies have only discovered and delivered a progressive coronavirus that could allow doctors to do just that, preventing more COVID-19 deaths in the coming months while we wait for vaccines and other effective treatments.

Doctors explained in mid-May that coronavirus does something surprisingly sneaky when it infects cells: it inhibits local production of interferon and delays the immune response, replicating the virus and infecting more cells. That is why many teams have started interferon-based tests, thinking that treating COVID-19 with interferon can prevent serious illness. A World Health Organization study failed to show that interferon can prevent death. But some development doctors may be able to run interferon therapy better and test more.
It all began in late September when some studies described a major interferon-related phenomenon that could increase the risk of death in Covid-19 patients, including young men. Genetic issues affect interferon which can worsen the prognosis until COVID-19 is diagnosed. That study suggests that by discovering a hidden interferon imbalance, doctors can determine which Covid-19 patients are at risk for serious complications.
This brings us to a pair of larger studies NBC News Published recently, which provides additional details about interferon issues that can lead to difficulties.
An international team of researchers published a study Science He says 10% of the 987 patients hospitalized with severe COVID-19 had antibodies that disable interferon. These are known as an antibody and can appear in autoimmune diseases or medical conditions where the body attacks itself. Patients Of the patients with tontibodies, 94% were men.
The study COVID is a human genetic endeavor, involving 200 research centers in 40 countries. It is much larger in space than the September study.
Interferon an tontibodies were absent in the group of 663 asymptomatic COVID-19 patients. Of the 1,227 healthy people in the control group, only 4 had tontibodies, the researchers said. If the data is accurate, then doctors treating COVID-19 patients can begin testing for interferon auto-tontibodies as soon as possible to catch potentially serious cases.
People who have automated bodies against interferon always have them. It is not a byproduct of coronavirus infection. It is not clear why other infectious diseases such as the flu have not brought these interferon issues to light in the past.
Dr. Vice President of Scripps Research. “These are some of the most important things we’ve learned about the immune system since the beginning of the epidemic,” said Eric Topol. NBC. Topol was not involved in the study.
This is not the only interferon problem identified by the Covid human genetic endeavor group. He also wrote in another study that says%% of patients with serious diseases had mutations in genes that control interferon. There are 500 to 600 such genes in the body, Dr Qian Zhang said, adding that they could identify further mutations. Zhang was the lead author of the second study. The findings may also explain why men of all ages are more affected by interferon problems than women.
“Interferon is like a fire alarm and a sprinkler system,” explained virologist Angela Rasmussen. NBC. Rasmussen was not involved in any of the studies. If the virus can suppress interferon activity, then people who suffer from a genetic interferon condition have a higher risk of developing serious illness.
“Alarms should sound everywhere in your body,” Zhang explained when the coronavirus arrives. “If you don’t get an alarm, you could get a large number of viruses everywhere.”
Screening for interferon anesthesia may be the norm for COVID-19 management, but scientists will need more data. NBC Notes There are more than 100 clinical trials involving interferon and coronavirus Medical. New interferon-based therapies may soon be out of trial. Doctors in Britain have just published a study Lancet Saying that the inhaled version of interferon beta-1a benefited COVID-19 patients. The randomly assigned people who received this drug were twice as likely to fully recover. This synergistic promising drug is SNG1001 which was the first detail in mid-July.
