Coronavirus: UK scientists identify drugs that may help severe cases

Scientists have identified a collection of drugs with the potential to benefit tens of thousands of patients who are admitted to intensive care with life-threatening coronavirus infections.
The breakthrough emerged from a major study of critically ill patients that revealed a suite of genes involved in antiviral defences and lung inflammation that leave people at greater risk of developing severe Covid disease.
The team, led by Edinburgh University researchers, spotted five genes that raised the risk of severe illness, pointing them towards a handful of drugs that are expected to help susceptible patients. The medicines will now be prioritised for clinical trials.

The analysis revealed key differences in five genes, named IFNAR2, TYK2, OAS1, DPP9 and CCR2, which partially explained why the sick patients became critically ill. Having identified the troublesome genes, the team was able to predict what drug treatments were likely to help.
One drug that holds promise for future Covid treatment is a rheumatoid arthritis medicine called baricitinib. This reduces the activity of TYK2, which the research suggests will help reduce dangerous levels of inflammation in the lungs. Another is an antibody-based medicine that blocks CCR2 and is in clinical trials for psoriasis.
