Contesting the psychiatric framing of ME/CFS

Article abstract:

Contesting the psychiatric framing of ME/CFS, by Helen Spandler, Meg Allen in Social Theory & Health, v 15 pp 1–15 [Published Online: 16 August 2017]

ME/CFS is a medically contested illness and its understanding, framing and treatment has been the subject of heated debate.

This paper examines why framing the condition as a psychiatric issue—what we refer to as ‘psychiatrisation’—has been so heavily contested by patients and activists. We argue that this contestation is not simply about stigmatising mental health conditions, as some have suggested, but relates to how people diagnosed with mental illness are treated in society, psychiatry and the law.

We highlight the potentially harmful consequences of psychiatrisation which can lead to people’s experiential knowledge being discredited. This stems, in part, from a psychiatric-specific form of ‘epistemic injustice’ which can result in unhelpful, unwanted and forced treatments.

This understanding helps explain why the psychiatrisation of ME/CFS has become the focus of such bitter debate and why psychiatry itself has become such a significant field of contention, for both ME/CFS patients and mental health service users/survivors.

Notwithstanding important differences, both reject the way psychiatry denies patient explanations and understandings, and therefore share a collective struggle for justice and legitimation. Reasons why this shared struggle has not resulted in alliances between ME and mental health activists are noted.

Excerpt:

The contested framing of ME/CFS

On the one hand, ME activists argue that a narrow focus on the psychological elements of the illness has blocked bio-medical research and treatment (Jason 2012). For example, in the UK, the Department of Health controversially invested five million pounds into researching the benefits of psychological therapies (‘the PACE trial’), whereas an institute recently established at the University of East Anglia as a centre of excellence for biomedical research into ME/CFS had to be crowdsource funded by patients. This highlights the difficulties medical researchers experience in securing grants for CFS/ME research (Kitei 2014).

Some commentators have noted that less research funding is spent on conditions where patients are seen as responsible for, or contributing to, their illness, as can be seen in the underfunding of research into lung disease and liver cancer (Johnson 2015; Dimmock et al. 2016). When an illness is framed as psychological, it is people’s H. Spandler, M. Allen reactions, emotions and behaviour, rather than any underlying illness, which become the focus of scrutiny, and it is a short step from this to the assumption that people are ‘responsible’ for their illness and recovery.

In addition, critics argue that assuming ME/CFS is a psychological problem has resulted in poorly designed research studies which may have included people without the condition and excluded those severely affected by the condition from the studies (Jason et al. 1997; Jason 2012; ME Association 2015; Tuller 2015). ME activists argue that this situation has:

diminished the legitimacy and belief in the severity of the illness among physicians and allowed the psychiatrists to appropriate the condition to their own realm of influence…and put pressure on governments to apply psychiatric labels in order to reduce work claims for illness compensations (Millen 2001, p. 8).

On the other hand, the psychiatric profession has portrayed ME activists as blocking progress by campaigning against any psychological or psychiatric research investment and treatments (Smith and Wessely 2014). Some psychiatrists and medical practitioners have criticised ME activists for their ‘strident’ denial of any psychological component to their illness as ‘frankly offensive’ by ‘stigmatising mental health patients and vilifying psychiatry’ (ibid: 218).

Yet both sides of this divisive debate have found it difficult to evidence their case. Whilst ‘psychology’ is seen as an important factor in people’s recovery from many types of illnesses, the psychiatrisation of ME/CFS means that psychology is often seen as the underlying determining factor of the illness, not just an additional element in recovery (Jason 2012). This assumption has been hard to prove, or indeed disprove.

Similarly, whilst ME/CFS activists can point to some physiological abnormalities in patients (Institute of Medicine 2015), to date they have been unable to generalise from these findings. Whilst more research and better diagnostic tests may well establish a physiological basis for the condition, the evidence is presently weak. Moreover, a clear-cut division between ‘mental’ and ‘physical’ is hard to sustain in practice. It is important to note that the discipline of psychiatry has considerably more power and influence than patients’ organisations and individual sufferers, so these debates are not conducted on a level-playing field. In the meantime, people who experience contested illnesses, like ME/CFS, face a particular struggle for legitimation or, what has been referred to as, ‘epistemic justice’.

Exercise tests suggest autoimmunity causes the exertion problems in CFS, FM & POTS

Health rising blog post, by Cort Johnson, 16 August 2017: Exercise Tests Suggest Autoimmunity Causes the Exertion Problems in Chronic Fatigue Syndrome, Fibromyalgia and POTS

Researchers and doctors get interested in ME/CFS in different ways. Many have a personal connection, but for David Systrom,  a pulmonologist, it was all about demand. He didn’t seek chronic fatigue syndrome patients out – quite the contrary.  When Systrom was given control of a clinical cardiopulmonary lab, he started doing invasive cardiopulmonary exercise tests (iCPET’s) on people with exercise intolerance. Once word of that got out, chronic fatigue syndrome, fibromyalgia, POTS and other patients starting pouring in.

It wasn’t the patients seeking Systrom out – it was their doctors; they finally had a place to send their strange exercise intolerant patients to. Rheumatologists, cardiologists, neurologists, and infectious disease specialists have gladly sent their patients his way for years.  It’s not a small number. Systrom suggests that 10 percent of people with exercise intolerance fit this profile. Those referrals have lead to 1,500 highly sophisticated exercise tests, about 700 of which were done on people with ME/CFS/FM/POTS.

Systrom’s had his eye on chronic fatigue syndrome (ME/CFS) for a while, but up until now he’s been looking at exercise intolerance in general. That’s why, despite the fact that he has one of the biggest, and certainly the most sophisticated, database of exercise results in ME/CFS, he’s mostly unknown to researchers and patients.

Armed with a grant from an anonymous donor to The Solve ME/CFS Initiative (SMCI) to support his work, Systrom, is for the first time focusing a study solely on ME/CFS.

Invasive Cardiopulmonary Exercise Testing (iCPET)
Systrom has taken exercise testing in ME/CFS to the next level with his invasive cardiopulmonary exercise testing (iCPET). Non-invasive cardiopulmonary exercise (CPET) testing can do a lot of things. It can demonstrate that exercise intolerance is present, define the aerobic and anaerobic contributions to exercise, determine if lung problems are present and others, but with an iCPET researchers can dig much deeper.

Systrom’s an acknowledged expert in the iCPET field; in 2013 he was the senior author of the first review paper on iCPET and in 2016 he co-wrote the first methodology paper explaining how to do it correctly.

One catheter goes into the pulmonary artery

Invasive CPET’s involve the insertion of catheters into the pulmonary artery and radial arteries that monitor blood flow, oxygen content and other factors. These catheters allow researchers to determine if the problems with oxygen are occurring in the lungs or in the muscles, where oxygen uptake is occurring and so on. Because iCPET can determine changes in venous blood O2 occurring with exercise, they’re able to determine how much oxygen the muscles are using. The technique can therefore be used to diagnose mitochondrial issues.

iCPET tests needed to identify three under-recognized causes of exercise intolerance, the third of which concerns ME/CFS:  preload failure or the inability of the blood vessels to provide the heart with enough blood to pump effectively.  Several studies suggest that preload failure is causing the small hearts in ME/CFS.

In the 2013 review article Systrom explained what happens (or should happen) when we exercise.

  1. Muscles need oxygen to generate energy.
  2. During exercise, increased breathing (ventilation) in the lungs and increased gas exchange between the lungs and blood provides more oxygen to the blood.
  3. First the heart increases it’s stroke volume so that it can shoot more blood out to the muscles.
  4. Once the heart maximum stroke volume is reached, the heart rate begins to increase in order to pump out more and more blood.
  5. In order to provide the increased levels of blood to the heart, the veins leading to it enlarge so that they can accommodate more blood.

It’s All About Oxygen
First, aerobic (oxygen-oriented) energy production mostly prevails. When the limits of aerobic metabolism are reached, though, one’s “anaerobic threshold” is reached. At that point, a non-oxygen way of producing energy called anaerobic metabolism becomes prominent. Two toxic byproducts of anaerobic metabolism, lactate and CO2, build up and cause fatigue, pain, etc.  (Anaerobic thresholds are identified during the CPET test by an abrupt increase in CO2 levels). Here’s the key part for ME/CFS, FM and POTS patients from Systrom’s 2013 paper:

“People with low anaerobic thresholds; that is, people who quickly exhaust their ability to generate energy aerobically and rapidly enter into anaerobic metabolism have one of two problems: either the oxygen isn’t getting to the mitochondria in their muscles or the mitochondria aren’t taking it up….

THREE PATTERNS
In a June interview, Systrom stated that about half of his patients have POTS/ ME/CFS or FM. When he tests them, a couple of different patterns show up – a pattern of dysautonomia, which reflects problems with the blood vessels, and reduced oxygen uptake pattern reflecting other problems.

  • Dysautonomia – the primary problem is inadequate venoconstriction; i.e. the autonomic nerves are not constricting the veins enough to propel sufficient amounts of blood (i.e. oxygen) to the heart for exercise or other activities to take place. Damage to the nerves in the arteries may be present as well.
  • Reduced skeletal muscle oxygen uptake -the  mitochondria are not taking in as much oxygen as they should.
  • Genetic issues – are not nearly as common as the other two, but Systrom can at times find genetic issues.

Inflammation correlates with symptoms in CFS

Research overview abstract:

Inflammation correlates with symptoms in chronic fatigue syndrome, by Anthony L Komaroff in PNAS August 15, 2017

It is not unusual for patients who say they are sick to have normal results on standard laboratory testing. The physician often concludes that there is no “real” illness and that the patients’ symptoms likely stem from a psychological disorder. An alternative conclusion, often honored in the breach, is that the standard laboratory tests are measuring the wrong things.

Chronic fatigue syndrome (CFS)―also called myalgic encephalomyelitis/chronic fatigue syndrome―is such an illness. Often, the condition begins suddenly, following an “infectious-like” illness. For years, patients do not return to full health. The illness waxes and wanes, and at its worst leads patients to be bedridden or unable to leave their homes. A report from the National Academies estimates that CFS affects up to 2.5 million people in the United States and generates direct and indirect expenses of $17–24 billion annually (1). The most widely used case definition (2) consists only of symptoms. This, along with typically normal results on standard laboratory tests, has raised the question of whether there are any “real” objective, biological abnormalities in CFS. In PNAS, Montoya et al. (3) report the latest evidence that there are such abnormalities.

Indeed, research over the past 30 y has discovered pathology involving the central nervous system (CNS) and autonomic nervous system (ANS), energy metabolism (with associated oxidative and nitrosative stress), and the immune system, as described in a detailed review (4). This Commentary will briefly summarize the evidence, providing citations only to work published since this review. I will then place the report by Montoya et al. (3) in context, and speculate about the pathophysiology of the illness.

‘The most common disease you’ve never seen’: how one woman turned her illness into a life-changing film

Telegraph article, by Alan Vincent, 11 August 2017: ‘The most common disease you’ve never seen’: how one woman turned her illness into a life-changing film

 

Jennifer Brea was 28 when she was bedridden with a high fever. As she explains, “I got better, but something wasn’t right.” She, like millions of people worldwide, had contracted Chronic Fatigue Syndrome, or myalgic encephalomyelitis, otherwise known as ME.

Suddenly, her life as she knew it, as a newlywed PhD student at Harvard University, was put on hold, as she became progessively more ill, losing even the ability to sit in a wheelchair. Doctors told her that her condition was “all in her head”. There was, and remains, no cure.

Then, four years ago, from her bed, Brea began to make a film about her experiences after keeping a video diary with her iPhone. In doing so, she gave a voice to those who suffer from “the most common disease you’ve never seen”, and encouraged scientists and medical professionals to plough their energies into unravelling a condition that has mystified physicians for years.

Unrest won a prize at Sundance film festival earlier this year, and became one of the first titles to be released with the support of Sundance Institute’s Creative Distribution Fellowship, which aims to empowering entrepreneurial Sundance filmmakers.

The Mail online asks: Why are doctors and patients still at war over ME?

Mail online post, by Jerome Burns, 15 August 2017: Why are doctors and patients still at war over M.E.?

How the best treatment for the debilitating condition is one of the most bitterly contested areas in medicine

  • Myalgic encephalomyelitis can leave those affected bedridden for years
  • It’s linked with 60 symptoms, most commonly a feeling of constant exhaustion
  • There’s been a long-running debate between doctors and patients about cause

Myalgic encephalomyelitis (ME) is a debilitating condition that can leave those affected bedridden for years. It’s linked with as many as 60 symptoms, the most common being a feeling of constant exhaustion — ‘like a dead battery’.

The condition first reached mainstream consciousness in the Eighties following outbreaks in New York and Nevada. By then it was officially known as chronic fatigue syndrome (CFS).

For a time, it seemed everyone knew someone who was affected by it, and it was derisively dubbed ‘yuppie flu’ because it seemed typically to affect young professionals.

For years there’s been a long-running and bitter debate between doctors and patients about its cause and how to treat it.

The lack of a clear physical cause meant many doctors dismissed it as all in the mind. This infuriated patient groups who insisted it was all too real and the result of an infection or immune system failure.

Even now, when it is generally accepted that ME/CFS is a genuine condition, it remains one of the most angrily contested areas of medicine. But the battle lines are no longer drawn just between patients and doctors: the medical community itself is at loggerheads.

The issue: the best way to treat ME. This has huge significance for the estimated 500,000 people in Britain affected by it. The official NHS treatment for their condition is delivered by psychologists and involves a combination of cognitive behavioural therapy (CBT) and graded exercise therapy (GET) which involves doing a little more each day.

The idea is that doing regular aerobic exercise would help patients a lot, but that they are held back by ‘fear’ of activity: the CBT is meant to overcome this.

Many patients and doctors claimed this combination provided little if any benefit.

This dispute has now broken out into the public arena in an extraordinary fashion. Two weeks ago the Journal of Health Psychology published what was effectively an attack on the official NHS treatment.

COULD IT BE CAUSED BY INFLAMMATION?
At the heart of the issue is what causes ME. Patient activists and some doctors consider it a physical disorder.

This ‘biological’ theory appeared to be reinforced by recent research from Stanford University in the U.S. that identified a new set of ‘messenger’ molecules in the blood that are part of the immune system and behave differently in ME/CFS patients.

New, sophisticated equipment allowed a team to run a very detailed analysis of the blood of 192 patients, comparing it with nearly 400 healthy people. They found that immune system messenger molecules (cytokines) that trigger inflammation and produce flu-like symptoms were higher in patients with the most severe symptoms.

An independent expert, Gordon Broderick, a systems biologist at Rochester General Hospital in New York, commented that it was a ‘tremendous step forward’.

Harsh criticism of big ME-study (Norwegian article with English translation)

The so-called PACE-the study is school example of poor research, writes journal editor. Thus, the fight rolls on ME/chronic fatigue syndrome.

The researchers behind the PACE-the study believes the study shows that training and cognitive therapy can improve or cure ME/CFS. Not all agree in the conclusion.

Looking at the Evidence (blog post by mrspoonseeker)

Chronic fatigue syndrome reality conflicts with medical study (in The Mining Journal)

American physicians have been strongly influenced by the PACE trial. This may be the result of our devotion to the concepts of “Evidence Based Medicine.” One simply has to publish a study, whether well-constructed or not, biased though it may be, perhaps even deeply flawed, and the results can be adopted and repeated as gospel.

The research community, on the other hand, has rejected the psychiatric model epitomized by PACE. They instead are looking for a physiologic explanation, whereby there is some actual, physical phenomenon at work.

FITNET’s internet-based CBT may impede natural recovery in adolescents with ME/CFS

Review abstract:

FITNET’s Internet-Based Cognitive Behavioural Therapy is ineffective and may impede natural recovery in adolescents with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome. A Review, by Simin Ghatineh and Mark Vink in Behav Sci (Basel). 2017 Aug 11;7(3). pii: E52

The Dutch Fatigue In Teenagers on the interNET (FITNET) study claimed that after 6 months, internet based cognitive behaviour therapy in adolescents with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), led to a 63% recovery rate compared to 8% after usual care, and that this was maintained at long term follow up (LTFU).

Our reanalysis shows that their post-hoc definition of recovery included the severely ill, the unblinded trial had no adequate control group and it used lax selection criteria as well as outcomes assessed via questionnaires rather than objective outcomes, further contributing to exaggerated recovery figures.

Their decision not to publish the actometer results might suggest that these did not back their recovery claims. Despite these bias creating methodological faults, the trial still found no significant difference in recovery rates (“~60%”) at LTFU, the trial’s primary goal.

This is similar to or worse than the documented 54-94% spontaneous recovery rates within 3-4 years, suggesting that both FITNET and usual care (consisting of cognitive behaviour and graded exercise therapies) are ineffective and might even impede natural recovery in adolescents with ME/CFS. This has implications for the upcoming costly NHS FITNET trial which is a blueprint of the Dutch study, exposing it to similar biases.

Is SEID comparable to research case definitions of CFS?

Two groups of American researchers debate the appropriateness of using case definitions for research purposes.

Article abstract:

Mistaken conclusions about systemic exercise intolerance disease being comparable to research case definitions of CFS: a rebuttal to Chu et al., by Leonard A. Jason, Madison Sunnquist, Kristen Gleason, Pamela Fox in Fatigue: Biomedicine, Health & Behavior
August 7, 2017 [Preprint]

The recent article by Chu et al. contrasted different case definitions that have been used to describe chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME). In particular, their study compared the new Institute of Medicine (IOM) criteria for systemic exertion intolerance disease (SEID) with three other ME and CFS case definitions.

We appreciate these investigators attempting to use and operationalize the new IOM criteria; however, we disagree with their main conclusion that the percentage of patients selected by the IOM criteria is comparable to the percentage selected by other research case definitions. This conclusion could potentially encourage investigators to use the IOM criteria for research purposes.

In this commentary, we discuss our observations of the Chu et al. article with respect to their methodology, illustrating how the conclusions of an investigation can be influenced by the manner in which case definitions are operationalized.

Article abstract:  

Differences of opinion on systemic exercise intolerance disease are not ‘mistakes’: a rejoinder to Jason, Sunnquist, Gleason and Fox, by Lily Chu, Ian J. Valencia, Jose G. Montoya in Fatigue: Biomedicine, Health & Behavior, 10 Aug 2017

Differences of opinion about how case definitions are operationalized should not be characterized as ‘mistaken.’ Despite limitations, our study provides insight into how systemic exertion intolerance disease (SEID) criteria perform early in the course of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) compared to other
case definitions.

To facilitate early, accurate diagnosis, research needs to be performed, ideally, prospectively with subjects who have not been ill for years. In addition, results of past treatment studies may not be applicable to many ME/CFS patients because criteria used for research differed from patients’ clinical presentations. To avoid this potential mismatch between research employing the new clinically-focused SEID criteria should be promoted, rather than discouraged.

This is why I quit exercise therapy

Buzzfeed news blog post, by Camilla Maxted, 6 Aug 2017: This is why I quite exercise therapy

When it comes to my illness, I’ve learned to listen to my symptoms, trust my body, and give it the one thing it really needs: rest.

Excerpt:

It turns out that the only thing more scary than developing a life-changing disease is finding that there is no effective help available. Reality drops away from you. Nothing in your previous life carries any weight any longer; nothing can give you strength or sense; all is swallowed into an enormous void, and the void is waiting for you, and it says: You’re on your own, and there is no resisting me.

After the worst phase of physical punishment for my efforts had passed, I also found that I’d lost the little function that I’d had before starting the exercise program. And when you get as bad as I was then, you become unable to advocate for yourself. You can’t leave your bed, and even if you could, you can’t hold a conversation in real time, because your brain won’t process things quickly enough.

There I lay, abandoned by the medical establishment – or had I abandoned it? Either way, I was full of fear, and the self-doubt instilled in me by the doctor remained. Should I try again, at some point? And what was going to become of me?

It was at that point, lost, alone, that I decided to do my own research. Sure, I’d done some light googling before, enough to find out that graded exercise was the only real option open to me (it was either that or cognitive behavioural therapy, designed to persuade me that I should think more positively and get active again – sound familiar?). But now I took a different approach, going beyond the official literature. I joined discussion forums, I started asking questions on social media, and, eventually, I learned to make sense of scientific papers.

As I dug deeper, I found that I wasn’t alone in finding the exercise programme damaging. Around the world there were hundreds of thousands – possibly millions – of people stuck in their beds like me, and in the UK a sizeable proportion believed they had been put there by exercise therapy. And the rest of the world kept on spinning, and nobody knew.

From my bed, I learned that chronic fatigue syndrome, or CFS, is sometimes also known as myalgic encephalomyelitis, or ME. And I learned that the history of ME/CFS is a story of people bewildered, in pain, and often severely disabled, and suffering the even greater cruelty of being told their symptoms are only in their mind.

On the internet I met people who had been told they were “sick, not ill”. I met people who had been informed that “you must want to die, then”. (And I spoke to several who at times had felt that death would indeed be preferable.) I read the stories of children who had been removed from their families due to their parents’ refusal to force them to exercise.

I also met – online of course – several sufferers who had lived for months or years in darkness, unable to speak or interact, just strong enough to drink liquidised meals and drag themselves to the bathroom when necessary. But in this darkness I also found hope, support, and a sense of community.

Increase in the Regional Cerebral Blood Flow following Waon Therapy in Patients with CFS

Research abstract:

Increase in the Regional Cerebral Blood Flow following Waon Therapy in Patients with Chronic Fatigue Syndrome: A Pilot Study, by  T Munemoto, Y Soejima, A Masuda, Y Nakabeppu, C Tei, in Intern Med. 2017;56(14):1817-1824 [Epub 2017 Jul 15]

Objective:

Chronic fatigue syndrome (CFS) is a complex disorder, with no consensus on therapeutic options. However, Waon therapy has been reported to be an effective treatment. The purpose of this study was to evaluate changes in the cerebral blood flow (CBF) before and after Waon therapy in CFS patients and to investigate the correlation between such changes and the therapeutic efficacy of Waon therapy.

Methods:

Eleven patients (2 men and 9 women, mean age 27 years old) diagnosed with CFS participated in the study. The disease duration was 8-129 months, and the performance status was 5-8 (on a scale of 0-9). All patients underwent CBF scintigraphy using brain single-photon emission computed tomography (SPECT) with technetium-99m ethyl cysteinate dimer (99mTc-ECD) before and after Waon therapy. CBF changes after Waon therapy were evaluated using a statistical analysis of imaging data, which was performed with a statistical parametric mapping software program (SPM5).

Results:

Waon therapy reduced symptoms in all 11 patients. We also observed an increase in the CBF within the prefrontal region, orbitofrontal region, and right temporal lobe. These results indicated that an improvement in clinical symptoms was linked to an increase in the CBF.

Conclusion:

The results indicated abnormalities of the cerebral function in the prefrontal region, orbitofrontal region, and right temporal lobe in CFS patients and that Waon therapy improved the cerebral function and symptoms in CFS patients by increasing the regional CBF. To our knowledge, this is the first report to clarify the CBF changes in CFS patients before and after Waon therapy.
