Long COVID - the Inflamed and Exhausted Disease? Plus, the JAK Drug Trial Boom
A major Harvard long COVID study validated an emerging theme: that the immune systems of long COVID patients are both inflamed and exhausted.
It should not be lost on anyone that this scenario (turned on and exhausted) also fits findings in the brain, autonomic nervous system, and muscles. It suggests researchers are zeroing in on core issues in these diseases.
The Harvard team didn't rest there. In an attempt to calm the hyperactive immune system down they immediately started a trial of a powerful drug that shuts down the immune pathways (JAK/STAT) that have become activated.
In fact, with multiple JAK trials underway, we're in a bit of a long COVID JAK inhibitor boom! Find out more...
Harvard researchers find an activated and exhausted immune system in long COVID patients - and begin a drug trial to try to fix it.
