Rowe said it was presented at a conference, as I recall.

Thanks. I think it could be this presentation. Hopefully they will publish a paper.

Orthostatic intolerance in CFS/ME

Prof Dr Frans Visser and Dr Linda van Campen, Cardiac Care Foundation

Prof Visser and Dr van Campen, are cardiologists who have developed a research interest in CFS/ME, especially the role of orthostatic intolerance. They described some of their current research in this area, and the use of pyridostigmine – a drug that is primarily used in myasthenia gravis – as a treatment option.

Prof Visser began by acknowledging that “orthostatic intolerance is a relatively new kid on the block when it comes to CFS/ME criteria.”

Discussing the prevalence of orthostatic intolerance in people with CFS/ME, Prof Visser acknowledged that it is very variable between studies, ranging from 30% to 59% prevalence – though in all studies, it occurs more frequently in people with CFS/ME than in healthy volunteers.

In his and Dr van Campen’s clinic, based on data from more than 500 patients, there is clinical suspicion of OI in 80% of CFS/ME patients. But in tilt-table testing, they see hemodynamic abnormalities only in around half of patients (44%).
How can we explain this difference in symptomatic complaints versus objective science, asked Prof Visser? The answer lies in the cerebral hypoperfusion, he explained, which is decreased blood flow to key parts of the brain.
Describing the findings of tilt table tests, Prof Visser showed that there is an abnormal decrease in cerebral blood flow when sitting and during standing in CFS/ME patients and that, even in the absence of abnormal hemodynamic findings (eg. POTS) there is abnormal cerebral blood flow decrease.

He concluded by highlighting that, in light on these findings, the still widely-held assumption that CFS/ME is due to deconditioning is in fact emphatically wrong.

Dr van Campen expanded on this, giving overview of research she and Prof Visser had undertaken using CPET testing and actometers.

“In 114 consecutive CFS/ME patients undergoing CPX and Sensewear activity armband we correlated the total number of steps from the Sensewear activity meter with the range of a normal VO2max,” she explained, before concluding that their data suggests that cerebral blood flow decline is NOT caused by deconditioning as evidenced by the %VO2max and number of steps, but is part of the disease of CFS/ME.

Details received this morning. Set to go...
Conference began with awards (in French) followed by a short video featuring Jen Brea @Jen B.

Liveatream audio volume very low [later corrected] so hope Jen's video will be available online.

Dr. Byron Hyde feels ME is a neurocirculatory disease and mentioned autoimmune vasculitis.

Ron Davis gave an outstanding summary of his infectious diseases, immune, and metabolomics research leading up to the "Metabolic Trap" hypothesis which he feels is "reversible."

So far an excellent conference, very well-organized....

the enterovirus is what he suspects causes hypoperfusion that would not rule out vasculitis . poorly working veins would explain poor blood circulation in a lot of people wit m .e .

He's going to have to make up his mind. Where did his enterovirus theory go?
Theory still there @Kati as far as I can tell.

He briefly covered ME outbreaks, patients he visited incl. at Royal Free and other sites around the world, showed a slide of Dr. Chia's enterovirus/ stomach tissue, reviewed manifestations of EV infections, etc.

The presentation seemed to be a shortened version of a longer one he had to compress into the 20-minute time slot. Hopefully full versions of all presentations incl. his will be made available.

@alkt highlights Hyde's current thinking in the post above:
