    Abstract:
    Persistent fatigue is one of the most common symptoms of post-COVID conditions, also termed long COVID. At the extreme end of the severity spectrum, some individuals with long COVID also meet the criteria for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), raising the possibility that symptom management approaches for ME/CFS may benefit some long COVID patients. We describe the long-term outcomes of a 19-year-old male who developed profound impairment consistent with ME/CFS after a SARS-CoV-2 infection early in the pandemic.

    We evaluated and treated him using our clinic’s approach to ME/CFS. This included a history and physical examination that ascertained joint hypermobility, pathological reflexes, physical therapy maneuvers to look for a range of motion restrictions in the limbs and spine, orthostatic testing, and screening laboratory studies. He was found to have profound postural tachycardia syndrome, several ranges of motion restrictions, and mast cell activation syndrome.

    He was treated according to our clinic’s guidelines for managing ME/CFS, which included manual physical therapy maneuvers and both non-pharmacologic measures and medications directed at postural tachycardia syndrome and mast cell activation. He experienced significant improvement in his symptoms over 30 months. His case emphasizes how the application of the principles of treating ME/CFS has the potential to provide a direction for treating long COVID.

    So, time.

    Ascribing any effect here is simply not valid. Even at 12 months it should take a huge amount of evidence to give credit to some intervention or another, otherwise this makes as much sense as giving credit to some dance ritual for having solved major flooding, years after it happened. As if there's some kind of... evaporative process happening. We need medicine to respect basic reasoning.

    By far the most common factor mentioned in recovery for long haulers is time. It clearly plays a significant role, and this has major implications for what the cause and resolution are.

    The most frustrating thing about this is that the fact that time is a major factor is significant, that whatever process is involved has to account for that, but it's barely researched because all medical research on chronic illness uses single points in time.

    Because whatever the factors are, there are people who recover spontaneously. They went to sleep feeling horrible and woke up not feeling ill anymore. Not always full resolution, but sometimes. So this factor can work on such a time scale. Sometimes it's slow improvement over days or weeks. Taking months makes no sense here other than natural recovery.

    Yep, this paper is not science, it's advertising. Advertising that ignores reality. There's probably a specific word for that.

    Interesting discussion on this.
    The article came across differently to me.
    I understood the authors to be saying that appropriate diagnosis and careful, well thought out interventions (that seem to have had some degree of success with PwME), when done early on, have a reasonable chance of making a difference in level of function in those with Long COVID.

    Agree that that point is one that needs to be noted more. There is no 'cure' currently, but we've gone through a decade where certainly in the UK many/most (?) received nothing on principle. Including for related conditions that began at the same time, trying things that might help in some and don't do terrible harm (and there might have been a clinical guide to help on who/when they tend to work), comorbidities and sometimes basic medical care - until recently (when 'MUS' has spread to other conditions) basically didn't get things those who weren't labelled would have done as standard.

    So given that 3 year time period is pretty key, far from taking other solveable issues off the plate/body - no matter how small they might seem - these things were purposefully accumulating in these individuals as a load of illness in a way others didn't have that.

    In the current situation that seems to be the best chance people have - decent advice that says that is the time period those around them need to get their head around taking it seriously for if there is to be a chance of any natural improvement/give people the best chance. And that informing future plans if the same people do recover but then end up taking a big dip again.

    The authors themselves note some or all of the recovery might have been spontaneous over time. But from reading this none of these ideas were applied without common sense judgement e.g. they looked into the history of allergies and asthma and tried out different things for POTS to see if they helped. And it is a case study rather than a trial and isn't too bad an indicator of how one might approach doing what is worth trying without suggesting this necessarily means he either had ME/CFS or that any of these things were a cure for LC.

    I can't see what good leaving someone without treatment for POTS does for ME with all the crashes and exertion of that for example. And whatever views might be on MCAS if someone had allergies and a certain combo of antihistamines helps with symptoms I don't get the issue and particularly if they've raged when their ME has gone on a downward tilt etc. And we know that not only is ME/CFS (and this is LC) probably different types but people who get it have different bodies and comorbidities and severities so until there is a miracle cure we need to get people's minds back around some sort of clinical approach.

    And for methodology purposes too - because if some things on that list might have been standard and help a bit and others are 'woo' and it is all put down to that woo thing we've an issue. But I do think that if we had decent clinics that could be making sure any standard things had been tackled that is more 'evening the field' vs leaving people untreated making for it being 'homogenous' sample isn't it? ie any trial has stabilised patients with whatever standard medical care is relevant to them before you see whether 'that one trialled treatment' makes a difference?

    How does this apply specifically to M.E? This could apply to many other health conditions.

    What type of manual maneuvers help pwME?

    Here's the thread on that earlier case series
    Petracek, L.S.; Suskauer, S.J.; Vickers, R.F.; Patel, N.R.; Violand, R.L.; Swope, R.L.; Rowe, P.C. Adolescent and Young Adult ME/CFS After Confirmed or Probable COVID-19 2021

    I wonder if we are going to see similarly detailed case studies for the other two people mentioned in that earlier case series.

    Yes, misrepresentation.

    That bolded sentence required a bit more of an explanation, I think. On the one hand, the ME/CFS patients have higher than normal range of motion in joints, but some of the joints have lower than normal range of motion? and both things are indicative of ME/CFS pathology?

    That is what they are saying but without a scrap of evidence.
    We don't even have evidence for success in PwME, or well thinking out, really.

    I have no idea what restriction of movement has to do with it, especially if it supposed to be related to more unrestricted movement - i.e. hypermobility.
    I get the impression that this group has lost the plot.

    Edit: cross posted with Hutan.
    Yes, this is getting a bit topsy-turvy.

    A Beighton score of 3/9 is normal.

    I'm not a physiotherapist, and I'm not sure what is being said about these other tests. But, as an example, that elbow extension test isn't saying that the man's range of motion at the elbow was 130 or 140 degrees - when, give or take a few degrees, 180 degrees would be normal. Instead, the authors seem to be saying that there was reported stretch at that joint at 130/140 degrees of elbow extension. Isn't there some subjectivity in that measure? A difference between a sensation of stretch at 130/140 degrees and 170 degrees, especially when assessed by another person, seems rather subtle to me. But perhaps I'm not interpreting that correctly? Can anyone interpret that bolded sentence for me?

    I think this is a median nerve stretch test. You probably put the hand into a position that already tightens the nerve - maybe wrist extension - and then extend the elbow. It would be a median nerve version of what is known as the sciatic stretch test - straight leg raise with dorsiflexion of the foot at the ankle.

    These tests produce discomfort and pins and needles in most people at some point. I had physios doing them on me when I had sciatica and carpal tunnel syndrome and coming out with 'expert advice' on my neurodynamics. Except that what they said didn't fit what I actually knew was the case from the images and my symptom pattern. Physios love these tests but they are pretty dubious. There is another one called the slump test for spinal nerve stretching in general. In an acute prolapsed disc the sciatic stretch test can be dramatically clear - able to raise the good leg to 70 degrees and the bad one to twenty with a yell of pain.

    I don't know who the authors on this are but I suspect at least one is a physio and this is typical of the sort of self-fulfilling work-up procedures they love to go through.

    The man's plasma histamine at 3.5 ng/mL was high (normal range <1.8 ng/mL). Histamine at that level sounds as though it could cause all sorts of symptoms. That is interesting. I wonder how common that is in ME/CFS and how many people benefit from various anti-histamines.

    And very mildly high chromagranin.

    High chromogranin a levels can be a sign of cancer, among other things, and yet this case study makes no mention of that possibility, or any tests done to rule that out.
    (Incidentally, as I googled chromogranin, there's a case study of a youngish man with high chromogranin who had what was initially diagnosed as functional dyspepsia - for which CBT is often prescribed - he turned out to have pancreatic cancer. Another example where dismissal with a 'oh, you just need to think about your symptoms differently and calm down' would not lead to a good outcome.)

    Just further on the mast cell diagnosis. To a man with a hammer, the world looks like a nail. Perhaps this clinic did consider a range of alternative causes for the histamine and chromogranin A levels, but this case study does not report that. There are a number of other diagnoses that would also fit. I think people going to specialist clinics need to be aware of the possibility that other diagnoses may not be sufficiently considered - a bit of confirmatory bias may be applied.

    I feel really uneasy about this. The young man is a bit worried about being so sick, and he has postural orthostatic tachycardia, which won't be helping with feeling calm. So, fair enough, he feels a bit anxious (the level of anxiety is only ever referred to as 'mild'). His symptoms seem to improve over time, so why leap into giving him escitalopram? Table 4 notes that he had 'improvement in response to stressors and response to sensory stimuli at a dose of 5 mg/day, but an increase in fatigue at 10 mg/day'.

    Escitalopram has some unpleasant or even dangerous side effects:
    Is masking what is probably a very normal and probably manageable level of anxiety really worth the risk of those side effects, some of which are also his existing symptoms? I doubt it.

    On low dose naltrexone:
    Reference 40 - the 218 patients study:
    We have a thread on it that is worth a read:Low-dose naltrexone in the treatment of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), 2019, Polo et al.
    It was an open label retrospective study; the clinic with the medical records that this paper was based on has since been closed down.

    Reference 41
    Forum thread here:
    Potential therapeutic benefit of Low Dose Naltrexone in [ME/CFS]: Role of Transient Receptor Potential Melastatin 3 ion channels, 2021, Cabanas et al
    Again, well worth a read. There were only 9 patients, they were recruited after having been on LDN for at least 4 weeks. So these patients had already demonstrated their willingness to consider the possibility that LDN was helpful. There were some rather random self-reported benefits - but given the open-label and framing, these mean little. The researchers found that the TRPM3 ion channels in the 9 patients were functioning like the TRPM3 ion channels in the 9 controls. But they didn't measure TRPM3 channels function in this study before the LDN was started.

    Citing these papers as evidence to justify prescribing any drug, especially to young people, should be unacceptable. Even the authors of the papers called for randomised controlled trials. We need better from people that are held up to be expert ME/CFS clinicians.
