Let's use our collective power and energy to fight through government bureaucracies and to educate the masses, there is plenty of work to go around, so more power to whomever would like to take this on.
I dont care if the CAA, the WPI, the NIH or the Republic of China comes up with answers for us I just want to get well. And I will support anyone that is working towards that end.

Discussion
Five domains of illness experience were derived empirically from multivariate analyses of large inter- national epidemiological and clinical datasets based on symptom reports of subjects with prolonged fatigue. These domains were robust across cultures and health-care settings and are consistent with the key criteria described in the 1994 international CFS case definition. They are best summarized as: pro- longed fatigue and musculoskeletal pain; impairedneurocognitive function; sleep disturbance; and symptoms suggestive of inflammation. From a psy- chiatric perspective, the only noteworthy variation is one of emphasis on the central role of mood disturbance. There has been a strong tendency in the medical and lay literature on CFS to suggest that depressive symptoms are simply an understandable psychological response to the severity or duration of
disability. These data argue that mood disturbance is a core component.

The present findings indicate that the core dimensions specified in the 1994 definition have construct validity and do not need to be revised. The International CFS Study Group also recommended that for research purposes, the diag- nosis of CFS should be made using validated instru- ments that allow standardized assessments of the major symptom domains of the illness. The present study supports that recommendation and suggests an empirical diagnostic algorithm similar to that used by the Centers for Disease Control and Prevention [51].

A great deal of research effort, particularly in mental health aspects of general medical care, continues to focus on whether such chronic fatigue states can be distinguished from other medical and psychiatric diagnoses and also from other similar medically unexplained syndromes (e.g. chronic pain, fibromyalgia, irritable bowel syndrome). We suggest that this international study supports the proposition that chronic fatigue states share a common and stereotyped set of symptom domains, and that these can be readily identified in the community and at all levels of health care. Consequently, it is likely that they share common risk factors, are underpinned by a common pathophysiology, and may respond to common treatment strategies. We also suggest that there is little to be gained by further reorganization of the diagnostic criteria, or the related diagnostic entities. It is time to consider whether chronic fatigue states should be included formally in future interna- tional classification systems both in psychiatry and in general medicine.
Conceptually, the present findings are consistent with the notion that the key symptom phenomena of chronic fatigue states are likely to share common central nervous system mechanisms, independent of any other precipitating illness (e.g. infection) or risk factors (e.g. prior mood disturbance).
A formal analysis of cytokine networks in chronic fatigue syndrome.
Broderick G, Fuite J, Kreitz A, Vernon SD, Klimas N, Fletcher MA.
Chronic Fatigue Syndrome (CFS) is a complex illness affecting 4 million Americans for which no characteristic lesion has been identified. Instead of searching for a deficiency in any single marker, we propose that CFS is associated with a profound imbalance in the regulation of immune function forcing a departure from standard pre-programmed responses...... These showed highly attenuated Th1 and Th17 immune responses in CFS. High Th2 marker expression but weak interaction patterns pointed to an established Th2 inflammatory milieu. Similarly, altered associations in CFS provided indirect evidence of diminished NK cell responsiveness to IL-12 and LT-α stimulus. These observations are consistent with several processes active in latent viral infection and would not have been uncovered by assessing marker expression alone. Furthermore this analysis identifies key sub-networks such as IL-2:IFN-γ:TNF-α that might be targeted in restoring normal immune function.
B-cell dysfunction (think EBV) and antibody mediated NK cell modulation of T-cells (antibodies are screwing up NK cells which are then screwing up T cells). CD 19 cells could be at the heart of CFS!Mol Med. 2009 Jan-Feb;15(1-2):34-42. Epub 2008 Nov 10.
Transcriptional control of complement activation in an exercise model of chronic fatigue syndrome.
Sorensen B, Jones JF, Vernon SD, Rajeevan MS.
Complement activation resulting in significant increases of C4a split product may be a marker of postexertional malaise in individuals with chronic fatigue syndrome (CFS). This study focused on identification of the transcriptional control that may contribute to the increased C4a in CFS subjects after exercise..... In conclusion, lectin pathway responded to exercise differentially in CFS than in control subjects. MASP2 down-regulation may act as an antiinflammatory acute-phase response in healthy subjects, whereas its elevated level may account for increased C4a and inflammation-mediated postexertional malaise in CFS subjects.
This study suggests that temporarily reducing cortisol levels sharply could snap the HPA axis back into proper functioning.Behav Brain Funct. 2008 Sep 26;4:44.
Evidence of inflammatory immune signaling in chronic fatigue syndrome: A pilot study of gene expression in peripheral blood.Aspler AL, Bolshin C, Vernon SD, Broderick G.
BACKGROUND: Genomic profiling of peripheral blood reveals altered immunity in chronic fatigue syndrome (CFS) however interpretation remains challenging without immune demographic context.
CONCLUSION: Dissection of blood microarray profiles points to B cell dysfunction with coordinated immune activation supporting persistent inflammation and antibody-mediated NK cell modulation of T cell activity. This has clinical implications as the CD19+ genes identified could provide robust and biologically meaningful basis for the early detection and unambiguous phenotyping of CFS.
You realize I could go on and on with this -give you 10 or fifteen studies to the one you pointed out. Some studies did not have positive results but they were almost all - except for the one you picked out and the ED - 'good ' subjects. Throw in the work that she's done with the CAA and you have a slam dunk in my opinion.PLoS Comput Biol. 2009 Jan;5(1):e1000273. Epub 2009 Jan 23.
Model-based therapeutic correction of hypothalamic-pituitary-adrenal axis dysfunction.
Ben-Zvi A, Vernon SD, Broderick G.
The hypothalamic-pituitary-adrenal (HPA) axis is a major system maintaining body homeostasis by regulating the neuroendocrine and sympathetic nervous systems as well modulating immune function.
A candidate treatment that displays robust properties in the face of significant biological variability and measurement uncertainty requires that cortisol be further suppressed for a short period until adrenocorticotropic hormone levels exceed 30% of baseline. Treatment may then be discontinued, and the HPA axis will naturally progress to a stable attractor defined by normal hormone levels. Perhaps most importantly, a treatment course involving further reduction in cortisol, even transient, is quite counterintuitive and challenges the conventional strategy of supplementing cortisol levels, an approach based on steady-state reasoning.
At heart we all want the same thing. If someone makes a mistake, I say forget about it and move on...We're only human. Let's give each of us a break -recommit to the main goal - healthy, happy, active livesRetro eek:

Are chronic fatigue and chronic fatigue syndrome valid clinical entities across countries and health-
care settings?

International Chronic Fatigue Syndrome Study Group
But it's "now" I have a problem with. In this week's WSJ article about the study finding unique proteins in the spinal fluid of ME/CFS patients, Suzanne Vernon is quoted as saying “It’s difficult to have a diagnostic test based on spinal fluid. You can’t just go poking everyone in the spine.” That bugged the heck out of me. I know that lumbar punctures aren't something to take lightly, but they are used as a diagnostic tool for serious neurological diseases, such as multiple sclerosis. Why not for ME/CFS? I would welcome a biomarker we could use for a diagnostic test, and I was disappointed that Suzanne Vernon seemed to wet-blanket the idea. I wish she'd spoken of the importance of biomarkers, or pointed out that the study shows CNS involvement, or that "authorities" can quit saying there's no medical evidence of disease. Or SOMETHING supportive.
If Dr. Vernon now regards her endorsement of the "Empirical Definition" as a "mistake" she should say as much and push for an accurate case definition. We live with this "mistake"."Forget about it and move on"? To borrow a Utah Phillips line, "The past didn't go anywhere."
What is the Associations position on the CFS research program at CDC? Do you support the CDCs empirical definition of CFS?
The Association has been very public in its criticism of the CFS Research Program at CDC. You can read a summary of our recent efforts. The Association does not support use of the CDCs empirical definition of CFS in federally funded research and has repeatedly urged that CDC discontinue selecting CFS cases for its studies using these guidelines. The Association has never funded any research based on the empiric definition, nor has any education supported by the Association been based on the empiric definition. Review the Associations applicant research guidelines for defining cases and its current eligibility criteria for the BioBank.
I'm not defending anyone here... I live in the UK, and so I don't have much of an insight into the CAA... But journalists often take a quote out of context, so it might be helpful to get a statement from Vernon on her opinion of the study. I'm only saying that because I know what the media are like, and often go out of their way to print something controversial, rather than representing the truth.
I think I read that the authors of the protein study have no intention of suggesting that everyone with ME should have a lumbar puncture, but they are going to use their initial findings of proteins in the spinal fluid to look for the same proteins in the blood of ME & Lupus patients. If any of those spinal fluid proteins are floating around in our blood, then they can use those as a very convenient biological marker. They say that's the next step of their research.
The Associations scientific director, Suzanne D. Vernon, PhD, notes, I am particularly excited about this study and the new avenues it opens. Pairing this treasure trove list of proteins with the biological and clinical resources in the Associations SolveCFS BioBank will quicken the pace at which these biomarkers can be verified and validated, hopefully shortening the pipeline from benchside discovery to bedside application. The contributions made by this group to understanding the biology of CFS and nPTLS could
not have come at a more timely moment for the field and the patient community.
Cort, did you see what people wrote there about your statements on the good doctor's blog?
http://treatingxmrv.blogspot.com/2011/02/politics.html
I still want to know exactly how much money the CAA received from the government contracts and exactly what it was used for, including "administrative expenses".
Why hasn't Susan Vernon spoken out strongly and publicly about what has always been going on behind the scenes at the CDC including the prejudicial attitudes towards us, right from the beginning of her very well paid employment at the CAA?
Why hasn't she or anybody else at the CAA spoken out about what CBS wrote about in another thread -- that the government agencies are scared that XMRV will prove causative?
Why is the CAA so incredibly slow in issuing an RFA after more than two years without one, while sitting on millions of dollars in earmarked research money?
Why are so many vital questions continuously unanswered?
I know you do, and that's fine. But this is not Corts Assiciation of America. It's a patients organization. And at this point the big majority of the patients is unsatisfied with the direction and leadership of the CAA.Acting like that may not be as catchy or compelling to the CFS community but I think its what we need and its effective.
I don't really care about the papers she co-authored with Reeves when she was at the CDC. After all, she chose to leave the CDC and join the CFIDS association. That was then, this is now.
But it's "now" I have a problem with. In this week's WSJ article about the study finding unique proteins in the spinal fluid of ME/CFS patients, Suzanne Vernon is quoted as saying “It’s difficult to have a diagnostic test based on spinal fluid.

Or SOMETHING supportive.
This particular article was supposed to answer any questions other than whether Dr. Vernon is being of service to the ME/CFS Community...
I can't answer for her but I think Dr. Vernon's work over the past few years speaks for itself. I'm more interested in the studies she's funding, the research she's doing. the researchers she's brought into this field and the Research Network and BioBank she's put together than in her making personal attacks on her colleagues - something that would probably viewed with dismay by many in the research community - thus undercutting her support.
Working in a professional manner that wins the trust of her peers in the research community is important. She been able to bring many new researchers to the field at the Banbury Conference (35% of whom had never studied CFS), in the studies the CAA is funding and in the grants she applied for ( seven institutions participated in the autoimmune grants). She's shown her ability to make connections outside the field.
This probably also shows up in the CAA's stellar list of candidates for the CFSAC community including Dr. Lipkin, Dr. Singh and Dr Holmberg and a few others.
Acting like that may not be as catchy or compelling to the CFS community but I think its what we need and its effective.
I also tend to take the "What have you done for me lately?" approach.
It's not Suzanne Vernon I have a big problem with. Her comment in the WSJ blog I thought came off sounding dopey - although I said at the time (and I'll say it again) I get what she was trying to say - that everyone would prefer a less-invasive test to be available for routine diagnostics, and hopefully we can get one. But the words in which it was expressed were kind of condescending. Her comments in other articles about the Schutzer study were better.
If it turns out we can't get a reliable blood test for ME/CFS in the near future, and we have to undergo lumbar puncture for confirmation of diagnosis for a while - or for all time - so be it. It's still about a billion times better than having no accepted diagnostic test.
It's Kim McCleary and her comments to the press about PACE that I consider beyond the pale, and to be in direct contravention to patients' interests.
