London, United Kingdom.
A blood test which examines the immune response to the coronavirus could serve to determine what sick are more probability of worsening, has announced this Friday a team of scientists from the United Kingdom.
Researchers from the Francis Crick Institute, King’s College London and the Guy’s and St Thomas NHS Foundation have examined the blood of 60 patients of COVID-19 London St Thomas Hospital and have found that more serious show a malfunction of the immune T cells and deficiency of basophils.
Besides proposing to carry out the blood test to all sick with the virus that they enter a hospital, the experts ask to do clinic tests to treat the most serious with the interleukin 7 drug, with the idea of reinforcing their immune system.
Adrian Hayday, one of the researchers at the Francis Crick Institute, noted that it was “a surprise” to see the effect of virus in the immune cells.
“They try to protect us, but the virus seems to do something to them destabilizes, because their number is reduced so dramatic “, he declares.
The changes they observed in their blood test of the 60 patients “were not subtle,” he said, and saw that those who showed these deficiencies in T cells and basophils appeared to be “more at risk of experiencing severe illness and to require intensive care. “

Check with a blood test the state of the immune system of the COVID-19 sufferers upon admission to the hospital, it would be possible to estimate his evolution and decide the treatment, affirms the expert.
The researchers note that greater knowledge of the virus effect at immune system can also help in developing a vaccine. EFE
