The Big Merge? Are Long COVID And ME/CFS Hypotheses Meshing?

By Cort Johnson in Health Rising.

This new ME/CFS / long-COVID paper, “Endothelial Senescence and Chronic Fatigue Syndrome, a COVID-19 Based Hypothesis”, highlights something we’d hoped would occur with COVID-19: new eyes being placed on, and new perspectives being produced on chronic fatigue syndrome (ME/CFS).

The group that wrote this paper is an interesting case in point. Their June 2020 paper, “Intoxication With Endogenous Angiotensin II: A COVID-19 Hypothesis“, proposed that endothelial dysfunction was a key aspect of COVID – and linked it to high angiotensin II (Ang II) levels. They suggested that the high Ang II levels in COVID-19 had caused “premature vascular senescence”.

That was intriguing given the really interesting place that high Ang II levels, and something called the RAAS or RAS paradox, inhabits in the ME/CFS/POTS universe.

The Paradox in Chronic Fatigue Syndrome (ME/CFS) and POTS

The paradox concerns the renin-angiotensin-aldosterone pathway that’s supposed to kick in when low blood volume levels occur. Even in context of the very low blood volumes found in ME/CFS/POTS, the pathway doesn’t kick in, and its critical endpoint, aldosterone, remains at normal or even low levels. This is despite the fact that the levels of Ang II – found in the middle of the pathway – tend to be very high.
