New criteria redefine ME

What are you, kidding me? Good news in the land of ME/CFS? Surprisingly: yes.

Every patient has her own nomenclature for her illness, because “chronic fatigue syndrome” has stuck around so long as a garbage diagnosis, and myalgic encephalopathy/encephalomyelitis has never been solidly defined. But now we have both a name and a set of criteria that make solid sense and should greatly aid research efforts.

The International Consensus Criteria was developed by scientists from 13 countries, after exhaustive research. (For a good summary and analysis, see this article by Kimberly McCleary, president and CEO of the CFIDS Association.) Here are some very important points.

1. The illness is defined foremost by the symptom that disables so many of us: post-exertional malaise, now with an even more specific name, post-exertional neuroimmune exhaustion (PENE). This is major. The popular perception of ME has been that it’s all about fatigue, due largely to the term “chronic fatigue syndrome,” which is both vague and misleading. Yes, we are certainly fatigued, but it’s because of PENE.

This is why all that “we can cure fatigue” quackery is so wrong at its very foundation. They intentionally conflate CFS with “fatigue,” which is shooting at the wrong target. I’m actually in the mood now to go pick a fight with one of them, like Teitelbaum, by asking “how does your fatigue product address neurosensory, perceptual and motor disturbances?” (Of course treating fatigue is part of ME, especially for people with milder cases who need help through, say, a work day.)

2. The definition of ME here is specific, yet flexible enough to allow for the range of symptoms that patients experience. The criteria call for a certain number of symptoms in a certain number of categories, all fitting inside the three broad categories of neurology, immunology, and energy production. All current patients can learn whether they meet the criteria for ME, and people who don’t know anything about it can be given a solid diagnosis by their doctor.

This means that one of the biggest problems with ME/CFS research — how the patients are identified as having it — has just been reduced quite a bit. Researchers will be able to use the consensus criteria to replicate each other’s studies, something that has been difficult in the past. People can find out if they’ve been misdiagnosed in some way, since ME symptoms can mirror so many other illnesses, including mental ones.

Now don’t close this page in a fit of red-hot fury or anything; I have the same disgust for Simon Wet Parsley* that so many of us do. But it is certainly true that patients with major depression and even bipolar disorder have been misdiagnosed, in both directions. This is unquestionably good, because those patients can likely get much better treatment for their illness. Additionally, people who have self-diagnosed ME/CFS because they feel tired all the time can now rule it in or out, and get the proper treatment for a different problem or illness, if needed.

3. It’s true that this consensus has only just been published in the Journal of Internal Medicine, and it may certainly end up being debated on both a large and a small scale. But a great deal of the animosity surrounding XMRV rests so squarely on the vagueness of defining criteria, so this is in any case a great step towards removing some of the argument. If you have been reading any ME/CFS discussions lately, that’s a Herculean victory.

I recognize that my excitement about this consensus comes partly from the fact that it’s designed and worded in a way that matches my own educated guesses about ME/CFS. I’m not completely unbiased — and please, if you have a different take on this, do post a comment as I personally have not heard any naysayers yet, and I want to know what problems, if any, exist with this. I remember reading the news of the original XMRV paper, and feeling cautiously optimistic. This, on the other hand, made me joyous. So my predictions are premature, but I don’t think they’re impossible.

Patients who match the criteria now have an excellent rebuttal to any “It’s all in your head” they might receive. It’s also an answer to another chestnut, “You just need to get more sleep.” It’s probably too optimistic to hope that some patients may also quit turning to quacks and snake-oil salespeople, now that the diagnosis/treatment situation has been better clarified, but what the hell, I hope this too.

I’ve called my illness “chronic fatigue syndrome” because of the impression that patients whose symptoms are predominately immune fell into that category, while “ME” was for people with predominately cerebral symptoms. I was partly right about the focus on brain dysfunction, but have learned since that many of my immune-seeming problems are in fact due to just that. (Insert joke here.)

Going through the criteria was surprisingly emotional for me. It’s one thing to fall into a vague category of patients; it’s another to show objectively that I meet the criteria for a much less vague illness. There were symptoms listed that I have in spades but haven’t previously seen described so perfectly, such as “recurrent feelings of feverishness with or without low grade fever,” under the category of “Loss of thermostatic stability.” In a sense it was like having someone validate my symptoms, some of which I’m prone to think are all in my head. By the time I was done reading and rereading the paper and the criteria, I’d decided to identify myself as having ME from now on, while referring to the illness in general as ME/CFS.

Although nothing at all has really changed, it feels a little like a change in identity. A change that I deeply appreciate.

* Real name Simon Wessley, the much-maligned U.K. doctor who insists that the etiology of ME/CFS starts in the mind. He’s close; it does start in the brain, but not the thinking part of it. Apparently his name becomes far more apropos when translated into and then out of another language, and thanks to Linda for pointing this out!

Weekend sendoff: Oh, you again?

Yes, it’s me again. 2011 has not, so far, left me with much blogging energy. There have been major transitions, some still in progress. I am optimistic that things will improve, since I also have a few other projects I’m eager to get back to.

Anyway, I wanted to share two articles about CFS and XMRV that sum up the situation very well. Both touch on the relationship between patients and researchers. The first is from the Chicago Tribune, with a good summary of the state of XMRV research. The die-hards dislike this writer, but I think she’s seeing the big picture and the article reflects that: there are a lot of CFS patients who believe in XMRV, but the research is not yielding more evidence in favor of it.

The chasm between the WPI and its supporters and many in the scientific community is emblematic of a new, modern-day dynamic in which patients keep close tabs on the work of researchers and feel empowered to challenge that work and form strong opinions about the quality of it.

An editorial in Nature goes into more depth on this aspect, and exhorts both sides of the argument to listen to and respect each other. (The first comment, by Brian Foley, mentions different etiologies, something I harp on a lot.)

The challenge for scientists in this field, as in any other that involves patients, is to understand and be motivated by the plight of the patient community without letting their research be swayed by it.

Good reporting on this “mess” is great to see in mainstream media like the Tribune and The Wall Street Journal. However, I’m wondering whether CFS patients, who have tried for decades to shed the images of laziness, mental illness, and hypochondria, aren’t developing a new stereotype for themselves: mouthy and unswayed by science. Obviously, this describes only a portion of the patient community, but as I’ve fretted before, I believe the rest of us may be thought of as guilty by association.

I don’t really try to convince people of which side they should be on anymore. I only ask for clarity of thought and acceptance of solid evidence. If XMRV is proven to be implicated in chronic fatigue syndrome, I will accept that scientific consensus just as I’ll accept the other one that may be forming.

I recognize that there are political and scientific considerations that do cast a reasonable doubt on all the XMRV criticism, and which I don’t follow as closely as many do. I might not be informed enough about those aspects. I also have encountered very little medical resistance and have a doctor who is actually interested to find out exactly what’s wrong with me. Many of the WPI followers have been legitimately burned by their experiences with medical science, and I think they come by their suspicions honestly.

So I follow the science, and hope that the pro-XMRV crowd at least take it into account, which too many do not. Suspicion is okay; conspiracy theory is going too far. Just as people demand understanding and respect from their doctors, so should they reciprocate.

A future I don’t want to see

Andrew Wakefield, that one-man wretched hive of scum and villainy, has been in the news again lately, thanks to reporting by Brian Deer that exposed him as not just incompetent, but an outright fraud. (Briefly, Wakefield knowingly falsified data in the now-retracted Lancet study connecting autism with the MMR vaccine, due to a glaring conflict of interest and a profit motive.)

Despite the mountain of solid evidence against him, however, some people still vehemently support him, claiming conspiracy theories and persecution, and citing their gut instincts. These people are not interested in the science, nor are they thinking critically. It’s all drama and emotion, with a giant dose of correlation-causation fallacy.

In another area of chronic illness, the debate over whether XMRV causes CFS has become nearly as polarizing as the divide between scientific evidence and anti-vaccination hysteria. It’s quite a different scenario, of course; Wakefield is up against that mountain of evidence while the XMRV-CFS connection has only been studied for a year, and a scientific consensus is not imminent.

Recently, I read a blog post by organic chemist David Lowe, who while expressing pessimism about XMRV, makes the important point that what we are seeing is the scientific process:

No, this isn’t looking good at all. It’s pretty typical, though, of how things are out at the frontiers in this business. There are always more variables than you think, and more reasons to be wrong than you’ve counted. A theory doesn’t hold up until everyone who wants to has had a chance to take some big piƱata-shattering swings at it, with weapons of their choice. So, to people outside of research: you’re not seeing evidence of bad faith, conspiracy, or stupidity here. You’re seeing exactly how science gets done. It isn’t pretty, but it gets results in the end.

Lowe’s post was mentioned briefly on Virology blog (thanks to Linda Vansteenwinckel for the links), which quoted the same passage I just did. Lowe does delve into the XMRV debate, but both his post and the Virology one are clearly emphasizing the point about how the scientific process works. Reading the comments, I found it interesting that the discussion of both posts nevertheless ended up as debates about XMRV, many of which largely ignored the salient point.

I see plenty of patients who do the same thing. They fixate on something that happened during the course of XMRV-CFS research — a certain delay here, a miscommunication there — and focus their decidedly pro- or anti-XMRV stance around it. The problem is, nobody can make a valid decision at this point. There isn’t even close to enough science yet, but it’s as impossible to reason with some patients as it is with antivaxxers or creationists. I’ve expressed my own doubts about XMRV but I have no plans to pick a side in this debate until a consensus at least begins to form.

All of this, plus the worrisome hero worship of Judy Mikovits, lead researcher on the first XMRV-CFS paper, has got thinking about the CFS community compared with the situation with Wakefield and vaccines. Let me emphasize before anything else that when I say “worrisome,” I in no way am accusing Mikovits of the kind of deliberate fraud, falsified results, and ethically egregious behavior that Wakefield displayed. I still believe she has to answer for her appearance at the AUTISMONE conference along with Wakefield, and her very unfortunate association of vaccines and autism, but I believe at worst XMRV won’t amount to anything, not that she is shady or deceptive.

What’s worrisome about hero worship of a researcher is that a scientific issue starts to become about the cult of celebrity. Those who are in the cult band together for reasons that may have nothing to do with science whatsoever — for example, feelings of gratitude and relief that a scientist is paying due attention to a disabling chronic condition. Those feelings are of course understandable, but in extreme cases they develop into an emotional bond with the researcher, such as those who continue to support their perceived healer Wakefield no matter what.

Is this the culprit? No one knows yet.

Consider a future probably many years if not decades away. In this future, XMRV has been solidly rejected as a causative factor in CFS. There is more than enough evidence against it and a scientific consensus on the matter. Research has moved on. In this future, given the current discourse about XMRV, I can very easily see the CFS community become as divided as the situation with those who vaccinate and those who don’t. Antivaxxers firmly reject any evidence that has proven them wrong, and isn’t some of the CFS community heading down that road? In this future, I worry that the people who unquestioningly follow and support Judy Mikovits will continue to fly the XMRV banner for life, exactly as the antivaxxers have done with regard to Wakefield.

And in a world where unreasoned screaming tends to get more attention than solid science, I worry that CFS patients in this future will end up with a worse reputation than we currently have — worse because it will be true. People who currently can’t discuss the scientific process or worse, studies that do not show XMRV in CFS patients, without immediately becoming defensive and argumentative may become the people who cannot and will not accept that process — just like the antivaxxers today. Assuming Mikovits herself doesn’t accept the consensus (which she might well do), her devotees, even more united in support now that she is a “persecuted” figure such as Wakefield, may become derided and ignored by the legitimate scientific community — just like the antivaxxers today.

(On the other hand, in a future where XMRV is proven to be a cause of CFS, I’m pretty sure that most of those who determinedly made up their mind against that connection will immediately switch to the scientific consensus and accept treatment. But anyway.)

Again, I emphasize that Wakefield entirely brought his demise upon himself, and in my opinion those who continue to follow him are effectively as bad as he is. By contrast, while Mikovits has many similarly devoted supporters, she didn’t gain them through bad faith and deception. That’s a huge difference. But the end result in my hypothetical future is similar to Wakefield’s antivaxxers: CFS patients become known as anti-science loons blindly following not just a discredited theory but also the person who came up with it.

As with the vaccine “debate,” the central problem is a respect for and understanding of science versus loud, emotional, and unfounded rejection of science. At the moment, those who vehemently support Mikovits and the XMRV-CFS connection can’t be characterized as rejecting science, although they may still be quite loud and emotional. But the potential for that current line of thinking to develop into true anti-science, especially in that hypothetical future. The CFS community often suffers from a dangerous tendency to play the “I just know in my heart” card without thinking critically. Or even lazily spreading rumors and bad science without doing due diligence, such as in this completely egregious post from Phoenix Rising, a CFS site that has the questionable reputation of being a respected source of good information.

This is a future I don’t want to see. I don’t want there to become a genuine lunatic fringe in the CFS patient community, and I certainly don’t want to be stigmatized by association. Already I’m sometimes embarrassed by inarticulate and impassioned, multiply-fallacious comments devoid of any objective facts or evidence by a few of my fellow patients who engage in discussion on the science. Should I give those patients a break, because I of all people know what it’s like to have problems with cognition and concentration? No. I’m not talking about errors and goofs due to memory problems or other issues; I am well and truly capable of that. I’m talking about what I continually advocate: retaining the power of critical thinking despite our illnesses.

Every single one of us who has the capacity to contribute (to even the smallest degree) also takes on the responsibility to raise the level of discourse, effect respectful dialogues, be patient with the continuing research process, and keep our community connected rather than divided. Please, let’s learn a lesson from Andrew Wakefield before it’s too late.
