Hooray for a good start!
The Association fully anticipates that the BioBank will evolve and expand over time. We hope to involve more clinicians in identifying patients using the proper criteria. We hope to have funding for home phlebotomy services. As our resources grow, we will invest more in the BioBank. We want the BioBank to be around for a very long time. This week's announcement is our first roll out; we are doing everything in our power to ensure that it can grow.
General Inclusion Criteria for CFS Subjects You must fulfill these criteria in order to be eligible for the current studies:
1. CFS initial presentation with a flu-like illness or an acute (48 hours) or subacute (four weeks) onset.
2. Fatigue persists for at least six months.
3. Post-exertional malaise lasting more than 24 hours.Inclusion is EITHER Canadian or Fukuda as diagnosed by one of the four physicians.
4. Significant cognitive impairment in short-term memory and concentration.
5. Age between 18 and 65 years at the time of signing the informed consent.
6. A female subject is eligible to participate if she is not pregnant, not within three months postpartum, and not currently lactating per self-report.
I'm a little concerned that 1. CFS initial presentation with a flu-like illness or an acute (48 hours) or subacute (four weeks) onset will exclude a significant number of ME/CFS patients. I don't think I could answer this in a positive way. Many of us are gradual onset but wouldn't be represented in the blood bank for comparison purposes.
I hope I'm reading this wrong.

Gracenote, this is the current criteria, and it does require infectious onset or acute/subacute onset with a max of four weeks. I understand that there are many patients who had gradual onset. As we have funding to expand the BioBank, we may have changes in the study criteria, and it is possible that longer onset patients will be included. I can't speculate on that any further, but I do hope we will be able to expand the BioBank to include more patients.
I'm with gracenote. This criteria does concern me. Jennie, do you have any idea why this criteria was included, and therefore excludes many PWMECFS?
Another topic - are there any plans to include patients diagnosed with ME/CFS by Dr. Bruce Carruthers, lead author of the Canadian Consensus Criteria?

I understand needing to start somewhere, but this will specifically focus on "viral" patients and will skew any results that come out of the studies. No one doing studies using BioBank blood would have access to a significant proportion of patients. We will not know if the findings would also apply to gradual onset patients. This concerns me.
The current study criteria were designed for scientific reasons, not political ones. The Association does not think gradual onset patients are not important, nor do we think gradual onset patients should not be studied. These criteria are a starting point, tied to the needs of current collaborations. When we can expand and include other patients, we will do so.
I'm absolutely not questioning the motives of CAA with this and do not think their intent is to exclude any ME/CFS patient. However, the end result will be studies that cannot be generalized to Canadian criteria CFS patients. It just seems to me that you've lost the edge for good research data before you've even started.
That's all I'm going to say. Maybe.
Hi Gracenote,
I think some of the more gradual onset people are also really post-viral. I saw a comment by yourself about your own history and it sounded pretty much post-viral to me (sorry if I am stepping over a line here referring to your history in this thread. I can remove it if you want. You mentioned your history in some other thread on XMRV)

Well, I'd say having the Glaxo Kline XMRV research draw its ME/CFS samples from the biobank, and therefore using the Canadian Consensus Criteria in major research, (as well as using it for the other ME/CFS samples chosen) is a fantastic roll-out of the biobank!
Help! I want to donate, but I certainly don't want to skew any results of research. My CFS did not start with an acute infectious onset. However, the symptoms of CFS hit suddenly (with severe vertigo and weakness to begin with), and in rapid-fire succession over several weeks. (It was 10 years ago -- so hard to remember.) With adjustments I continued to work my desk job for 16 months (against my doctor's wishes). It was a toxic workplace, by the way. My colleagues thought they would have to drive me home when I finally left on short-term disability. I have never been able to return to full-time employment.
So, this isn't acute onset, but is it sub-acute? Do I donate? Anyone?
This looks like a good project. Good that neuro-cognitive impairment and post-exertional malaise (PEM) are requirements, especially the PEM. I wish PEM was a requirement for all studies.
Great news re the XMRV study.
Like Gracenote I was thinking that the first criteria is quite restrictive (and I am all in favour of being restrictive) but maybe it is good that it is like this, initially at least? All research ends up excluding patients for one reason or another, so I wouldn't worry too much at this stage so long as they can get enough samples. One problem is for people who are sick a long time they may have trouble remembering the specifics of their history re the first criteria. They may be post-viral but not quite remember timing.
But at the end of the day I would rather they be over-restrictive than over-inclusive, as being over-inclusive seems to have been a bigger problem with ME/CFS studies. It doesn't mean that the results don't apply to people who fall a bit outside of the restrictive criteria, and that these people won't benefit from the research.
