The issue with looking into various blood markers for long covid (ME/CFS, really) is that, with a complex immunometabolomic syndrome like long covid, there's so many interacting systems that have derangements. Even if you find some biomarker for it (of which this is not the first, for example, complement C4a is quite correlated with ME/CFS), it doesn't mean that the system that biomarker relates to is the root cause of the issues. It may be downstream of the root cause or part of a cycle of positive feedback.
It would be very nice to have a cheap and clinically validated test for long covid / ME/CFS though, for sure.
I really wasn't expecting low cortisol to be one of the main blood indicators of long COVID, but I guess that makes sense given the reports of lethargy. With the smell and/or taste issues reported...
I really wasn't expecting low cortisol to be one of the main blood indicators of long COVID, but I guess that makes sense given the reports of lethargy.
With the smell and/or taste issues reported by some, I assumed, like the article touches on, that there could be nerve cell impact.
Also thought the research reporting the Epstein–Barr virus re-activation was also unexpected, but I'm curious to see what further research finds on this and similar matters.
While the science is interesting, I really hope for the people impacted by this that an effective solution is found that allows them to resume normal living.
