    Mark - I tried both links in this para and they didn't work for me - I got a Googledocs page each time but without a document:

    "Also included with the letter are academic references in support of the call for the use of CPET, and the list of organizations and advocates who signed it. You can read the letter and supporting information here, and the letter sent to clinicians is available here."

    Hi Sasha,

    Are you logged in to google? Only the links work fine for me. Not sure if logging in is a factor - you know by now how I am with technology - but it might be :)

    Can you see the docs when you're logged out, Bob? I couldn't - it told me I had to sign in.

    Anyway, technicalities apart, it's interesting that the letter to clinicians is to those clinicians who've signed up to be part of the study - a great piece of advocacy, I thought, going straight to the clinicians on the ground and bypassing Dr Unger. Those clinicians need to be aware of the issues themselves.

    Thanks, Mark, and to everybody involved in this.

    I often use my dry sense of humor (which is not always apparent to everybody) to try to cheer up folks on the internet groups, but on this subject we need to be SERIOUS. There is a long history of prejudice at the CDC towards the ME/CFS community and especially patients. It's not just stigma and bias. While there are some slight indications of movement in the right directions I don't think we can trust them EVER. The problems go into the higher levels of management and always have.

    There was an anonymous patient's input about the CDC program on this thread earlier this year.

    Thanks Roy I must have missed that from January. Does this comment from anonymous mean that these things were being tested for:

    If so in what way? Thanks. Little confused with what went before and what is now being looked at. I realise it is multi-stage, but some clarification of the objective testing done before would be appreciated. Thank you.

    Hopefully someone will answer your question better than I can at present due to heavy brain fog.

    Anyway! Thanks for this article, Mark.

    The outcome of this major CDC study will impact PWME all over the world when it comes out so those of us outside the US as well as within it should be joining in with this.

    Strange, I just signed out of google and tried those links, and it took me straight to the documents without asking me to sign in. Maybe try clearing your browser's cache first? I think this has happened before with shared google docs; most people seem to be able to see them publicly OK, but a few get asked to sign in. They're shared to 'everyone with the link' so I'm not sure what else to do.

    Thanks Roy and Firestormm for digging that up. I tried to find detail on what exactly is being tested but didn't get very far with that. Note that, in the letter, the reference to viral testing and NK cells says 'if not already included in the study protocol', so it seems like nobody else has been able to find out the detail of those tests yet either. I think that's the point really: the devil is in the detail on these things. What exactly you test for, and how, will determine what you will find. And what decisions you make about that will probably depend on your prejudices to some extent, so there's a lot of room for experimental bias in those decisions.

    The principle that study protocols should be announced in advance and openly reviewed is gaining a lot of traction these days - I do think that's a far better way to conduct scientific investigations, especially for publicly-funded studies of controversial subjects with significant public interest in the results. It's therefore very important to clarify the detail of these tests, and if the tests being used aren't going to look for the things we want them to look for, we can then press for other tests to be included. At the end of the day, if the tests that the community wants aren't included, it seems likely that the meaning of the study's results will be bitterly disputed and perhaps rejected by the community, which will continue to have consequences down the line, so if the CDC wants to resolve these issues, it's in their interest to include the tests we ask for. I shudder to think how ME/CFS advocacy might evolve in the future if the CDC doesn't get it right this time.

    The exercise testing is particularly troubling: the evidence seems to suggest that plain VO2 max testing as opposed to repeat testing won't show up the PEM - I think there's a quite clear and compelling logic to that - and if they only test using a protocol that doesn't find the abnormalities, that could have very negative consequences. The same kind of problem may apply to the viral and immune testing, I just don't know. That's why I'm hoping that we will get some clarification on those details now - we've asked for a reply by Aug 31st so perhaps the detail of these issues will all become clearer by then.

    I think this is a very good action. It's one thing to criticise the outcome of a study after the fact but if you can say, 'we pointed out these shortcomings before the study began and the authors chose to ignore them' then that's a whole different ballgame. We need to be on top of these things as they're starting, if we can, before we can be accused of bias because we don't like the results.

    I agree that publicly-funded studies should disclose. They should also be disclosing to their participants.

    My brain must not be working today... I'm certain someone on this thread wrote that the diagnostic tests in this study remain unknown. How can this be? Don't study participants have to be told what is being done to them as part of 'informed consent'?

    Are research study details now part of National Fatherland Security?

    Thank you Mark and for all those who were involved in this work.

    How appropriate that this follows Simon's article about Dr. Snell's new study on repeated CPET testing.

    If the CDC really wants to show that they consider ME a serious disease, as they have stated, this is their opportunity to prove it!

    It seems that the CDC wants to put their past history with ME/CFS behind them and have openly admitted that they consider ME/CFS a serious disease. I challenge them that they should put their money where their mouths are. If they are putting money and effort into a multi-site study, do it right - the first time around. This is a great opportunity to show us that:

    1- You are listening to us
    2- You really believe that this is a serious biological disease
    3- You take into consideration the peer-reviewed studies out there that show the hard facts of these objective findings.
    4- You are using the funds allocated to us (ME/CFS patients) in the most effective manner
    5- There is transparency in what you do

    I really hope that this letter will be looked at seriously and taken into account. In either case, it will become apparent soon to all of us watching whether the CDC is serious about this serious illness.

    Dr. Unger should be reminded too of the ME Primer's Laboratory/Investigative Protocol. It includes the test for PENE, a 2-day CPET (using the Stevens Protocol), as well as laboratory tests to measure NK cell function and viral load, including enterovirises:

    Laboratory/Investigative Protocol: Diagnose by criteria. Confirm by laboratory and other investigations. A broad panel of tests provides a more robust basis to identify symptom patterns, abnormalities and orient treatment.

    Routine laboratory investigation: CBC, ESR, CA, P, RBC Mg, vitamin D3, B12 & folate, ferritin, zinc,FBS,PC, Hb A1C,
    serum electrolytes, TSH, protein electrophoresis screen, CRP,creatinine, ECG (U+ T wave notching), CPK and liver function,
    □ rheumatoid factor, antinuclear antibodies, urinalysis, essential fatty acids,CoEnzyme Q10, immunoglobulins, diurnal cortisol levels, TTG, serotonin

    Additional laboratory investigation: (as indicated by symptoms, history, clinical evaluation, lab findings, risk factors) 24 hour urine free cortisol,
    DHEA sulphate, ACTH, chest x-ray, hormones including free testosterone, panoramic x-ray of dental roots, amino acid profile,
    abdominal ultra sound,lactose/fructose breath test

    Further testing with specificity to ME, if and as indicated. Some tests are in the research stage but can identify abnormalities and focus treatment. Viral tests should be interpreted by a physician experienced in these infections.
    Pathogen: Enterovirus; Tests: RT-PCR, serology, stomach biopsy
    Pathogen: mycoplasma; Tests: DNA-PCR, serology
    Pathogen: EBV, CMV, HHV-6; Tests: DNA-PCR, serology, antigenemia
    Pathogen: Borrelia burgdorferi; Tests: DNA-PCR,serology, Western Blot
    Pathogen: Clamydia pneumonia; Tests: DNA PCR, serology
    Pathogen: Parvovirus B19; Tests: DNA-PCR,IgG, IgM,

    Immune system profiles: *NK cell function & cytotoxicity; B & T-cell function: IgG,IgG subclasses 1-4;IgA, IgM (shift from T1 to T2), cytokine/chemokine profile panel (94% accuracy): IL-8, IL-13, MIP-1β, MCP-1, IL4,flow cytometry for lymphocyte activity, □ ↑37 kDa 2-5A RNase L immunoassay – defect/ratio & bioactivity, food sensitivity panel, chemical sensitivities, stool for WCB - D-lactic acid bacteria balance, ova & parasites, autoimmune profile, Intestinal dysbiosis:IgA & IgM for intestinal aerobic bacteria in serum, □ ↑ leukocyte elastase activity in PBMCs, IgG food intolerance test,toxoplasmosis

    Neurological & static testing: *SPECT scan with contrast - ↓ cortical/cerebellar region cerebral blood flow (rCBF) in the frontal, parietal, temporal and occipital & brain stem regions - more brain involvement indicates increased illness severity,MRI of brain(increased T2-weighted images in high white matter tracts & loss of GM volume) & rule out MS, MRI of spine (dynamic disc bulges/herniation , stenosis), sleep study (stage 4 sleep, sleep pattern & rule out treatable sleep dysfunctions – upper airway resistance syndrome, sleep apnea, etc.)

    PENE: A 2 consecutive day comprehensive 8-12 minute cardiopulmonary exercise stress test (measuring heart, lung, and metabolic function) - only ME patients have significantly worse scores the second day & abnormal recovery from exertion. * Exercise tolerance test with expired gas exchange - (2 consecutive days) – measure cardiovascular, pulmonary & metabolic responses at rest & during exercise: peak oxygen consumption VO2 or VO2 at anaerobic threshold (AT) - decline of 8% or greater on test 2 indicates metabolic dysfunction, post-exercise blood analysis - increase in sensory, adrenergic and immune genes - increase in metabolite receptors unique to ME

    Energy metabolism/ion transport: ATP profile identifies insufficient energy due to cellular respiration dysfunction
    further ATP related parameters, superoxide dismutase and cell-free DNA Respiratory:pulmonary function test Cardiovascular: Tilt table test to confirm OI (70 -80% tilt, measure HR continuously, BP periodically – 30 min or presyncope); Cardiac output decreases - left ventricular dysfunction in the heart; 24-Hour Monitor for suspected arrhythmia, NMH/POTS, myocarditis (Note: Repetitively oscillating T-wave inversions &/or T-wave flats, typical of ME, may be subsumed under non-specific T-wave changes.)

    These tests, used to confirm a diagnosis of ME, would allow ME patients to be removed from the more encompassing CFS classification. "The need is not only for a case definition," according to Dr. Unger's June 5 letter to patient organizations and independent patient advocates, “but also for reproducible standardized approaches to applying it, as well as for biomarkers to refine subgroups within the overall CFS population.”

    Thanks Mark and all the patient organizations and advocates. I'm thrilled that you guys are on top of this issue and are taking action.

    I am concerned that a letter to Dr. Unger probably won't accomplish anything unfortunately. The CPET omission was pointed out to her at the last CFSAC and she didn't seemed moved by the arguments. How many times has she received letters and heated testimony about taking down the CDC toolkit - and she has not even considered taking it down while the new one is being written. All the while, respected doctors and researchers on CFSAC were making the recommendations as well.

    The letter to clinicians is a brilliant idea! These folks will probably be the ones that could put the most pressure on her. I would strongly suspect that these good ME/CFS docs would have called this study flaw out to the CDC even in absence of this letter to them (or one would hope).

    May I suggest that the patients write each one of the study centers and encourage them to do this correctly? Especially anyone that is a patient at one of these sites. The good doctors should absolutely put their foot down with this nonsense and I can't imagine it would take much arm twisting for them to agree.

    Do we have a link to a list of study sites??

    So back to the CDC, I believe the real question is:
    How do we actually break through to them and optimize our chance for meaningful change? What's our options:

    Going above Dr. Unger's head:
    If memory serves, I believe just at the last CFSAC (or possibly FDA meeting?), a letter(s) had been written to her superior and I believe she said something to the effect of "he just handed the letter to me to handle". I remember cringing at that very moment. It still might be a valuable route down the line however, but it's very tricky to navigate.

    How about going to Sec. Sebellious directly? IMO, she has never done much for us (CFSAC) so it's difficult to imagine she will now.

    President Obama? As I understand Bob Miller has lost the White House connection once his contact left the position.

    So overall, going above her head may be a strategy for down the road (hopefully there is a better path than I realize).


    Getting a meeting with Dr. Unger:
    One of the more frustrating problems in dealing with some of these agencies, is not that they deny our requests, but that they don't explain their reasoning for it. How can we present evidence to rebut their argument when we don't know what it is? If Dr. Unger were willing to meet with a small group of advocates and have a meaningful conversation, it's possible we can influence some of the testing. Maybe some docs need to be in on the meeting. I think the most important point would be to get people that she respects at the table, specifically researchers that understand how to set up study designs.


    In my opinion, getting these key people (docs, researchers, etc.) to buy into a meeting with her would be vital. Then they could send her a request for it. That would be the path that I think would be most fruitful.

    Now, the advocates that sent the letter may already have a stage 2 and stage 3 planned if she does not respond or if she poorly responses. That would be terrific to hear (If so, I realize that they may not want to tip their hand at this point). There are people like Steve K from the CFSAC that may be able to advise us as well (unless it's a conflict of interest for him.)

    We really need someone that understands the bureaucracy in Washington I think. I wonder if Wanda Jones might tell us how to complain in a highly-effective, response driven way??

    I think using the biomarkers eg nk function particularly bright nk cell function along with other viral markers as well as cd8 t cell dysfunction would be a good start.and are only going to help further research on our illness and make it more respected. hopefully this type of testing will be made available world wide to help diagnose ME.

    "Abnormally low NK Cell activity and high viral loads are consistent findings in patients with ME/CFS. "

    They're also found in patients with clinical depression, apparently, so it might be better to concentrate on something else. Reduced T-cell responsiveness &/or T-reg abnormality, muscle fibre abnormalities, glial activation, spinal fluid pressure and proteins, autoantibodies, active HHV6 or RNA enterovirus etc? It has to have specificity as well as sensitivity otherwise it allows the CDC to get away with their usual old rope.

    They should use a handgrip strength test as well which would allow to include severely affected patients in the CPET.
