    P.5

    "Other exciting studies include a new collaboration with the brilliant virologist, Dr. Bhupesh Prusty at the University of Würzburg, Germany. Using a new, cell-based assay system, we are hot on the trail of both the identity and the biological control of the activity in ME/CFS blood that causes fatigue. This “fatigue factor” looks like it could be the same thing that coordinates the mitochondrial and metabolic features of the cell danger response (CDR) and inflammation5, changes impedance in the nanoneedle10, inhibits recovery from illness by blocking the healing cycle9, induces a dauer-like state11, and triggers collagen remodeling over time that can cause acquired forms of Ehlers Danlos-like syndromes. If successful, these studies will help fill in missing details in how suramin, copaxone, and elamipretide (SS31) might work to treat ME/CFS."

    Just wanted to bump this up to link Dr. Bhupesh Prusty's presentation he gave at the NIH Conference earlier this year.

    Where is the breakthrough? Did I miss something? Looks like no suramin trial for CFS in 2020.

    And my question is do we have data that shows that “patients who are able to recover still have a life-long risk of recurrence”?

    It would be good to get clarification on that @Andy . Apart from being able to exercise you could say that I had 'recovered' until something triggered this relapse at the start of 2019, so I'm intrigued by what they mean.

    I must admit that I find the 'something in the blood' findings from three (?) different labs quite exciting. But then I don't even begin to understand the details of what I've read!

    Also are the ones who recover a subset with different aetiology? Without that biomarker can we know for sure?

    I'm not saying that it isn't worthy of studying those in long term remission or possibly recovered. Just wary of language that generalises or hypes & might set false expectations.

    Edited - to clarify their language not @Andy's!

    I suspect we don't, at least nothing very solid. I think he may be referring to the fact that a proportion of ME patients report that they've had good remissions followed later by relapse, to the point that it's become a commonly recognised (as opposed to actually researched) feature of one subset of patients.

    I've been able to be quite active in my remissions as long as I did not lift weights. Bodyweight exercises, hiking (I live in the northern part of Norway, we have tall mountains to climb), using a bike as my main mode of transportation and doing lots of uphill biking.. And then crash.

    Yeah I think this is pretty much confirmed from clinical observations and something that would require long-term funding to formalize so that's not happening.

    This is basically: as far as we know, with more evidence for than against but the deciding factor, money, not being available to settle it. Relapsing-remitting course seems to be rather common and we need to know more but as it stands clinical observation is solid.

    (excitedly examines Figure 8 for the characterisation of the metabolic signature of ME/CFS....)

    Here's Figure 8:

    Oh, it's just a picture of 12 silos....
    My impression is that we are still a long way from having a 'metabolic signature' for ME/CFS. It looks to me as though researchers are still ironing out technical issues in this and still figuring out what is important to look at.

    I'm happy the Naviaux lab is doing its work. The idea that cells releasing ATP in response to cellular stress is involved in the cause of ME/CFS sounds like a reasonable thing to look into. But the newsletter, starting with its title that promises a breakthrough in ME/CFS and autism, overclaims, I think. And that reduces the credibility of the team, in my eyes.

    Completely agree.

    I am increasingly irritated by researchers hyping their work. Apart from generating false hope, the field is never going to make progress unless researchers are more honest about what is really known, what is merely hypothesis and what is actually a dead end.

    By contrast, Maureen Hanson and team were far more honest in their recent metabolomics paper. They have some possible findings but were already pointing to the need for a different approach in metabolomics, such as looking beyond blood for samples and using an exercise challenge. There is much less to get excited about here, but I respect the team for their candour and rigour.

    And wasn't there a replication attempt of the original Bob Naviaux study that still hasn't seen the light of day - or have I got that wrong?

    Can't agree more with you @Hutan and @Simon M
    As you said, it is dishonest toward patients and prevents progress and I would add discredits all the good work done by others by giving ammunitions to ME skeptical doctors. It is so easy for them to believe that all research is bullshit and that there is nothing to look for when patients come to them with weak studies.

    As someone who gets asked to advise the big funders on these things I have to say that this is unimpressive. We need hard data and caution.

    He was talking about it being released in the Fall (2017?), then late Fall, then early in the New Year (2018?) then nothing further was heard.

    funding blurb never a good sign if more effort has to be put into self promotion than actually producing research data but this has been the way of business hype for at least a century .

    I find Naviaux's work interesting and worth pursuing, but probably in the DARPA mould of potentially high-impact but low-probability. For example, his work on ASD is innovative, but I note that all papers on purinergic signalling being involved in ASD are from him; no other research group seems to have picked this up to with follow-up studies to test and confirm this theory. This despite the significantly higher funding and researcher interest in ASD compared to ME/CFS.

    @Simon M,

    I was in that replication study and since it’s been like three years since I donated my blood, I emailed the Naviaux Lab to see if and when the Study will be published. I got a reply saying basically that they’re still massaging the data, but they plan to publish some day.

    I find this disappointing.
