The IOM panel on ME/CFS held its second (and likely final) public meeting on May 5, 2014. On display near the meeting room was this painting by Robert Van Vranken: Untitled (Everything at once, or one thing at a time?). (read more about the painting here) Written on the wall within the painting is the beginning of a quote from Prometheus Unbound, “Hear the sum of the whole matter in the compass of one brief word . . .”
To hear the sum of the whole matter in one brief word: this is precisely the challenge before us. How do we convey the full sum of ME/CFS – all of the issues, science, suffering, truth – in a brief word? When we say ME or PEM or cognitive dysfunction, will the IOM hear the full compass of what we mean? And can their diagnostic criteria – in a few brief words – transmit the fullness of that knowledge to the world?
This was the overarching theme of the public session on May 5th: communicating the reality of ME/CFS, and the uncertainty over whether the message was heard.
Agenda Structure
The agenda for the meeting was organized around gaps in the panel’s knowledge. A patient panel was asked to address obstacles in interacting with the healthcare system. Dr. Leonard Jason presented data on challenges and issues in the diagnostic criteria. Dr. Akifumi Kishi presented on sleep disturbance and Dr. Gudrun Lange presented on neurocognitive impairment, two issues that rank high in studies of ME/CFS symptoms. Every invited speaker was given a list of questions by the panel to answer in their presentations.
Taken as a whole, the speakers emphasized the core symptoms of PEM, sleep disturbance and cognitive impairment, and Dr. Jason addressed key issues in devising diagnostic criteria. These are critical areas for the committee to consider. Some advocates asked why no immunologist or expert clinician like Dr. Peterson was invited. But there are committee members with that expertise: Dr. Klimas for clinical immunology, and Drs. Klimas, Bateman, Lerner, Natelson and Rowe for experience treating people with ME/CFS. The panel does not have expertise in sleep or cognitive impairment, and Dr. Jason’s expertise in ME/CFS criteria issues is unparalleled. The meeting agenda structure plugged some of those holes for the IOM panel.
Patient Presentations
Two patients (Joe Landson and Bob Miller) and two caregivers (Denise Lopez-Majano and Annette Whittemore) spoke on the obstacles that ME/CFS patients face in diagnosis and healthcare. The presentations were moving, and all four acknowledged their good fortune in being able to get as much from the healthcare system as they have.
Joe Landson and Annette Whittemore pointed out that patients usually know more than their doctors, but remain hopeful that they will find help and confirmation of the diagnosis. Annette told several stories about doctors refusing to offer treatment to her daughter Andrea because she carries the CFS label. Denise Lopez-Majano talked about how doctors gave her no guidance on how to care for her sons or help them recover. Even basic advice about PEM and cognitive impairment would have reduced their suffering. Bob Miller described how it wasn’t until he found Dr. Peterson fifteen years after getting sick that he finally received adequate diagnostic testing and treatment.
Both cognitive impairment and PEM featured prominently in the presentations. Joe talked about how the “clutch in his brain has snapped,” and that even simple cognitive tasks are now beyond his capabilities. Denise described her son Matthew losing focus while speaking or eating, as if “his brain was stuck on hold.” All the panelists described the unpredictability and severity of PEM, offering specific examples. I’m not sure if the IOM panelists keyed in on the significance of one of Denise’s comments: that her sons were prescribed exercise only after they were diagnosed with ME/CFS.
Dr. Lily Chu and Dr. Klimas were both interested in the presenters’ thoughts on the name of this disease. While all four were emphatic that “CFS” should be abandoned, only Annette Whittemore offered an alternative: Ramsay’s disease. Denise, Bob and Joe all declined to specify what name they preferred. Many advocates saw this as a squandered opportunity. None of the speakers addressed the fact that ME already has a diagnostic code, nor did they connect the name question back to the diagnostic criteria.
The sense I got was that the speakers felt put on the spot by the name question, as if they were being asked to speak for the entire advocacy community, but I think they could have offered their own opinions. The IOM requested we address the name question in written comments for this meeting. In my own written submission to the IOM panel, I said, “If your case definition resembles the traditional definition of myalgic encephalomyelitis, as I believe it must, then I urge you to retain the traditional name as well.” I hope many other people expressed their opinions, too.
Dr. Jason and Criteria Challenges
Dr. Jason was asked to address many questions in his presentation, and given only 30 minutes in which to do it. I strongly recommend watching the video of his presentation to get the full details. In my opinion, the most important take away was the issue of reliability and criterion variance.
Studies have shown that anywhere from 50-90% of people who meet the Fukuda definition also meet the Canadian Consensus Criteria. Dr. Jason said that one possible explanation for this wide variation is that doctors are not applying the criteria consistently. Without an agreed upon set of biomarkers or assessment tools, there is potential for great differences in the actual application of any case definition.
One way to solve this problem is with an assessment tool like the DePaul Symptom Questionnaire. Dr. Jason presented data showing that the DSQ can distinguish between ME/CFS and depression with 100% success. However, the DSQ is not as good at distinguishing ME/CFS from autoimmune diseases like lupus or multiple sclerosis, and his research is ongoing.
Another way to create better diagnostic criteria is to use frequency and severity cutoff scores. This means that we don’t just ask if the person has a symptom, such as dizziness. We have to ask how frequently the person is dizzy and how severe the dizziness is. Dr. Jason presented a powerful slide showing that when a definition requires symptoms to occur a little of the time and be mild (referred to as 1/1), almost 34% of healthy controls meet the Fukuda definition. But when symptoms must occur about half the time and be moderate in severity (referred to as 2/2), healthy controls are almost completely eliminated.
The many questions from the IOM committee members may give us clues about what they are grappling with behind closed doors.
- Why is PEM not reported by 100% of patients? Answer: self-report questionnaires are not perfect, patients may have adapted coping skills to reduce PEM, or it may not be present in 100%.
- Is both frequency and severity required? Answer: identifying low frequency is important because it is less debilitating to patients.
- Impact of even higher cutoffs, gradual onset, psychiatric comorbidity, gender, ethnicity, controls, and good day vs. bad day? Answer: much of this has not been studied, and data is limited by the collectors (such as biobanks).
- How do we create a definition that is not too complicated for clinicians to use? Answer: focus on the core symptoms, and give doctors tools like questionnaires and scoring rules to help them make the diagnosis.
This issue of creating a simple definition came up during the patient presentations, too. Several people supported a one sentence description of the essence of the disease. In order to be inclusive, subtypes were suggested as ways to separate patients within that broader category. To be honest, this makes me nervous. It opens the door to a broad definition, with subtypes used to truly delineate those with this disease. I’m not sure that’s much different from what we have now. However, Dr. Jason did present his data on the core symptoms (PEM and cognitive dysfunction), and showed that other symptoms may cluster patients with immune or autonomic abnormalities. That paradigm was well reflected in the patient presentations.
Sleep and Cognitive Dysfunction
Following in the theme of core symptoms, Dr. Akifumi Kishi presented his data on sleep dysfunction in ME/CFS. I found his presentation very difficult to follow, and was disappointed that he did not provide a more comprehensive survey of this area of research. His data show that ME/CFS patients have abnormalities in their sleep stage transitions, but not in the actual stages themselves. The data also show that ME/CFS patients slept better after exercise, which is completely at odds with what many of us have experienced.
Dr. Kishi was pressed hard by the panel on multiple issues related to study design, statistical power, outcome measures, and comparison to overtrained athletes. Dr. Kishi could not answer many of these questions due to a lack of data or failure to consider the issues during study design. It was disappointing that his studies have been so small and so preliminary, and I’m not sure how useful this data will be to the IOM panel.
Dr. Gudrun Lange gave an overview of cognitive dysfunction in ME/CFS, including her fMRI studies and patient evaluations. Overall, her data show that ME/CFS patients have impaired processing speed and working memory. In untimed tasks, they show little impairment. Decreased attention and concentration, less information available “online,” and an inability to organize learning and make quick decisions are all manifestations of the dysfunction. Her imaging studies show that even when ME/CFS patients complete the same tasks at the same level as healthy controls, they need to use more of the brain to do so.
Dr. Lange was questioned on comparisons to other groups, such as sleep deprived controls and patients with fibromyalgia or ADHD. She also highlighted the differences between ME/CFS cognitive dysfunction and those with dementia or stroke. ME/CFS patients are very different, and testing conducted by neuropsychologists not familiar with the disorder can appear to give normal results when the impairment may actually be severe. While Dr. Lange said that no short form testing has been validated in ME/CFS patients, she suggested giving a patient 6 or 7 steps of complicated driving directions and asking them to repeat it back. We rarely can.
It was fitting for the meeting to end on the subject of cognitive dysfunction, since that had been a significant focus of the patient/caregiver panel. And I can share one example of my own cognitive fallout from attending the meeting. I traveled to the meeting with a friend by car (unable to hold directions in my head, as Dr. Lange had highlighted). I had the following text exchange with my husband after a pit stop on the way home, perfect evidence of me losing focus and substituting words:

The Elephant Not In The Room
One audience member commented to me that this meeting was very different from the January public meeting because of the absence of protesting advocates. Bob Miller said during his remarks that patients are protesting the meeting because they have no faith in the system. If the patient community actually believed the IOM process would help them, Bob said, the room would be filled.
My position on participating in the IOM process is well-known. I’ve been criticized for it, as were the advocates who chose to participate as panelists at this meeting. I won’t revisit the controversy in detail here. All I can say is that while some people noted the absence of many advocates, that absence made it easy for the panel to focus on its own agenda. When they asked for opinions on the name, they only heard the uncertainty of several panelists and whatever was submitted in writing. Anything the other advocates would have said was simply lost. Those of us who have chosen to provide input to the committee are trying to represent the diversity of opinion in our community, but I’m sure we are not fully successful.
“Hear the sum of the whole matter in the compass of one brief word.” Have we done enough to tell the IOM panel the truth about this disease? Have we done enough to point them in the right direction, and give them evidence sufficient to reach the right conclusions? Were the protesters heard through their silence? Have we been effective in combining the power of that silent protest with input from those willing to speak and write to the panel? Will it be enough?
We can only guess, and hope, and try, and wait.
P2P Agenda Fatigue
The Agenda Documents
I obtained these two agenda documents from NIH through a FOIA request. The first is titled “DRAFT Agenda” (previously obtained by another advocate, as well) and the second is titled “Agenda Example.” Neither document is dated, but circumstantial evidence suggests that both were drafted after the January 2014 Working Group meeting.
The Draft includes a list of possible speakers, including several advocates to address the “Patient Perspective.” My name is on that list, but I have not been contacted by anyone at NIH at any time about serving in that capacity. I don’t even know who put my name forward. Whether an invitation will be extended to me remains to be seen.
The Key Questions as presented in the Draft and Example documents are likely out of date, now that the systematic review protocol has been published. The Questions from the evidence review will structure the meeting, but the agendas are important indicators of NIH’s perspective and overall approach to the meeting.
Framing With Fatigue
Both of the documents include the same description of the overview that will begin the meeting:
Just to be sure you didn’t miss it, here’s is the framing for this meeting on ME/CFS: Overwhelming fatigue or malaise as a public health problem. Not ME/CFS as a public health problem. Not post-exertional malaise as a public health problem. Not cognitive dysfunction and disability as a public health problem. To NIH, “overwhelming fatigue” is the public health problem.
This is so wrong. It ignores what we’ve been saying about our experiences for years. It ignores the science on PEM and cognitive dysfunction. It ignores the fundamental question of what disease or diseases are being included in the CFS bucket. In fact, it steps back in time to the Oxford definition: overwhelming fatigue alone.
The real public health problem is that since 1988, CFS has been a wastebasket and dumping ground for people with unexplained chronic fatigue. Some of those people have depression, anxiety, MS, and other illnesses. Some of those people have medically unexplained fatigue. Some of those people have a disease characterized by PEM and cognitive dysfunction.
To lump all of that together as a public health problem of “overwhelming fatigue” completely and utterly misses the point. It perpetuates the hand waving and blurred lines in the government’s approach to my disease, and there’s just no excuse for it at this point.
Treatment Barges In
At the May 2013 CFSAC meeting, Dr. Maier said that treatment research was part of the evidence review, but she portrayed it as relating back to the case definition question:
But now we know that the evidence review will ask about treatment harms and benefits, and the characteristics of subgroups, responders and non-responders. The agenda documents reveal what this treatment focus will look like.
The Draft Agenda focuses on tools to measure outcomes, rather than comparative effectiveness of treatments. The Agenda Example document is very different. Here are the treatment presentations from that document (each topic allocated 20 minutes):
So we have an evidence review that lumps all the case definitions together, including Oxford. And we have an agenda that gives more time to CBT and GET than it does to symptom-based medication. And there is nothing here on disease-modifying treatment, like rituximab, Ampligen, or antivirals.
The topic selection and allocation of time among these treatment topics sends a subtle but powerful message to the Panel of non-ME/CFS experts, especially in light of the failure to distinguish among the case definitions at the outset. Previous evidence reviews, including AHRQ’s review from 2001 and the Brurberg, et al review published in February found no significant differences among case definitions or treatment outcomes, but those reviews were not set up to critically examine those differences. And as I’ve already pointed out, this current review assumes that differences among definitions represent subtypes and not separate diseases.
Design Flaws
The agenda documents show that the P2P Workshop is fundamentally flawed. The meeting is framed with the public health problem of “overwhelming fatigue.” The evidence review will include studies on adults with fatigue, and exclude those with unspecified underlying diagnoses. All the case definitions are lumped together for the purposes of assessing the reliability of those definitions and the effectiveness of treatments.
The evidence review and meeting agenda should begin with the proper scientific question: are ME and CFS the same disease, separate diseases, or points along a spectrum of fatiguing illnesses? That was the original starting question in the AHRQ evidence review contract, by the way. But it’s gone. The decision was made (not sure by whom) to assume the answer: that it is all one disease, separated only by subgroups. That assumption is the fatal flaw in this entire enterprise.
Remember that the P2P outcome will be decided by a panel of non-ME/CFS experts. We don’t know how they will be screened for bias. We won’t know who they are until shortly before the meeting. We will have no input into their selection.
This is not good science. This is sloppy, not precise. To revisit Dr. Maier’s jury analogy: this process will ask the allegedly impartial jury (selected by only one side) to reach conclusions based on evidence that has been marred by bias and assumptions. Maybe they will reach the right conclusions, or maybe the deck is stacked against us.
We have to find ways to speak out about this. I’m working on something right now, and there will be ways for you to express your own concerns. I hope you will join me.
