Studies on CBT & GET for ME/CFS are misleading, says Swedish prof

Article abstract:

There have been a number of studies on Cognitive Behavioral Therapy (CBT) and Graded Exercise Therapy (GET) for ME/CFS based on a treatment model where the disease is perpetuated by cognitive processes. Although the studies are flawed and the model lacks scientific support, the treatments are described as evidence based.

The studies are non-blinded and rely on subjective outcomes. There are no objective measures of adherence. The diagnostic criteria vary, and the participating patients often have one or several psychiatric diagnoses apart from suffering from chronic fatigue. The underlying model has no theoretical foundation and is at odds with physiological findings. Surveys suggest that the efficacy of CBT is no better than placebo and that GET is harmful. Therefore, cognitive behavioral therapy and graded exercise therapy for ME/CFS are not evidence based.

Activity patterns in response to symptoms in patients being treated for CFS

Research abstract:

Objective:
Cognitive-behavioral models of chronic fatigue syndrome (CFS) propose that patients respond to symptoms with 2 predominant activity patterns-activity limitation and all-or-nothing behaviors-both of which may contribute to illness persistence. The current study investigated whether activity patterns occurred at the same time as, or followed on from, patient symptom experience and affect.

Method
Twenty-three adults with CFS were recruited from U.K. CFS services. Experience sampling methodology (ESM) was used to assess fluctuations in patient symptom experience, affect, and activity management patterns over 10 assessments per day for a total of 6 days.

Assessments were conducted within patients’ daily life and were delivered through an app on touchscreen Android mobile phones. Multilevel model analyses were conducted to examine the role of self-reported patient fatigue, pain, and affect as predictors of change in activity patterns at the same and subsequent assessment.

Results
Current experience of fatigue-related symptoms and pain predicted higher patient activity limitation at the current and subsequent assessments whereas subjective wellness predicted higher all-or-nothing behavior at both times. Current pain predicted less all-or-nothing behavior at the subsequent assessment.

In contrast to hypotheses, current positive affect was predictive of current activity limitation whereas current negative affect was predictive of current all-or-nothing  behavior. Both activity patterns varied at the momentary level.

Conclusions
Patient symptom experiences appear to be driving patient activity management patterns in line with the cognitive-behavioral model of CFS. ESM offers a useful method for examining multiple interacting variables within the context of patients’ daily life.

Postexertion ‘crash,’ not fatigue per se, marks CFS

Medscape Medical News article, by Miriam Tucker, November 04, 2016: Post exertion ‘Crash,’ not Fatigue per se, Marks Syndrome

Article extract:

The name “chronic fatigue syndrome” is being phased out not just because it is viewed as trivializing a condition that renders many patients completely or nearly bedbound but also because it gives the misleading impression that the illness is characterized simply by prolonged unexplained fatigue.

In fact, ME/CFS is characterized by multiple heterogeneous symptoms, with PEM, often described as a “crash” or a significant worsening of already-present symptoms, being a near-universal experience.

“Many studies show that physical exertion can help with insomnia in healthy people, and even people with other medical conditions such as depression, anxiety, or even heart failure. But in ME/CFS patients, physical exertion exacerbates their symptoms,” conference cochair Lily Chu, MD, from Stanford University, Palo Alto, California, told Medscape Medical News.

“The way these patients present is very different from healthy people or people with other medical conditions.”

Indeed, recent diagnostic criteria for the illness, including the February 2015 Institute of Medicine report, require PEM among other symptoms to make the diagnosis of ME or ME/CFS as opposed to older definitions of CFS. However, the Centers for Disease Control and Prevention continues to endorse a 1994 CFS definition that lists PEM as an optional criterion, but does not make it mandatory for the diagnosis.

What Is PEM?

At the IACFSME conference, Dr Chu presented findings from her group’s study of 150 patients diagnosed with the 1994 criteria who completed a survey about their symptoms after physical or cognitive exertion or emotional distress.

The majority (89%) reported experiencing PEM after both types of triggers, but 10% reported no effect after emotional distress, whereas overall physical exertion elicited significantly more symptoms than did emotional distress (seven vs five; P < .001).

Although fatigue was the most commonly exacerbated symptom, more than 30% of patients also reported cognitive difficulties, sleep disturbance, headache, muscle pain, and influenza-like feelings. Some also reported gastrointestinal, orthostatic, and mood-related exacerbations.

Timing and duration of symptoms varied among respondents and per respondent, but 11% reported a consistent post trigger delay of at least 24 hours, whereas 23% said that their symptoms typically lasted for 3 or more days.

 “PEM consists of more than just fatigue and pain. It’s an exacerbation of multiple symptoms, some of which are atypically associated with exertion,” Dr Chu told Medscape Medical News.

She added, “PEM can be difficult for clinicians and patients to identify. We suggest patients keep a diary for a week or two, documenting symptoms and activity so we can look at and see relationship of activity and timing, duration, and intensity of symptoms.”

PACE-gate: when clinical trial evidence meets open data access

Article abstract:

Science is not always plain sailing and sometimes the voyage is across an angry sea. A recent clinical trial of treatments for chronic fatigue syndrome (the PACE trial) has whipped up a storm of controversy. Patients claim the lead authors overstated the effectiveness of cognitive behavioural therapy and graded exercise therapy by lowering the thresholds they used to determine improvement. In this extraordinary case, patients discovered that the treatments tested had much lower efficacy after an information tribunal ordered the release of data from the PACE trial to a patient who had requested access using a freedom of information request.

The most extreme consequence of ME/CFS – trauma & premature death

Livets bilder (Life images) blog post, 25 October 2016: The most extreme consequence – trauma and premature death  (Originally written in Swedish)

In this post I will write about something that I see as the most extreme consequence of what I call secondary system related stress. Something that is not “just” about worsening an existing condition, but when the system-related stress, adding to a person such damage that it could be counted as an additional condition. A new diagnosis. And a risk of a premature death.

When I wrote an earlier post about how my own emotional reactions have changed over time due to the cumulated stress, I remembered that I somewhere read about ME/CFS and PTSD (Post Traumatic Stress Disorder) triggered by healthcare.

I found an interesting article describing how Dr. Nancy Klimas found her way into further research about ME/CFS. In the 1990s, she studied how people with chronic diseases were affected by a natural disaster. One of the patient groups were people with ME/CFS. The study showed that people with chronic disease developed PTSD in a higher level than those without any chronic disease. People with ME/CFS also showed an exacerbation in their chronic condition. But she discovered something else as well: Even those ME/CFS sufferers who were not at all affected by the trauma during the natural disaster had higher rates of PTSD. This was something that differed from the other groups of chronically ill. After further investigation, she found an explanation in the patients’ healthcare situation:

“Yet compared with people with other chronic diseases, CFS patients, even those who hadn’t lived through the trauma of a hurricane, had notably higher PTSD rates, she found. Digging deeper, she found that CFS patients had actually been distressed by their medical experiences. A common theme in the trauma was an exposure to a health-care situation that was demoralizing and demeaning, she says.”

Dr. Nancy Klimas also said in an interview in the Miami Herald 2009:

“I’ve had patients who met posttraumatic stress disorder criteria, where their trauma was their interaction with their physician around this illness. They came to a doctor with Chronic Fatigue Syndrome; they left the doctor with PTSD.”

So, it is a long known fact that people with ME/CFS are at risk of developing PTSD related to community support systems. I have not found any specific studies on ME/CFS and healthcare triggered PTSD. However, right now there is an important survey study in progress, designed to investigate secondary mental illness in people with ME/CFS linked to external factors, such as how healthcare personnel treat their patients. It is web based and open to everyone with ME/CFS to join.

ME researchers identify danger of contamination in ME/CFS genomics study

Research abstract:

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a debilitating disease causing indefinite fatigue. ME/CFS has long been hypothesised to have an infectious cause; however, no specific infectious agent has been identified.

We used metagenomics to analyse the RNA from plasma samples from 25 individuals with ME/CFS and compare their microbial content to technical controls as well as three control groups: individuals with alternatively diagnosed chronic Lyme syndrome (N = 13), systemic lupus erythematosus (N = 11), and healthy controls (N = 25).

We found that the majority of sequencing reads were removed during host subtraction, thus there was very low microbial RNA content in the plasma. The effects of sample batching and contamination during sample processing proved to outweigh the effects of study group on microbial RNA content, as the few differences in bacterial or viral RNA abundance we did observe between study groups were most likely caused by contamination and batch effects.

Our results highlight the importance of including negative controls in all metagenomic analyses, since there was considerable overlap between bacterial content identified in study samples and control samples. For example, Proteobacteria, Firmicutes, Actinobacteria, and Bacteriodes were found in both study samples and plasma-free negative controls.

Many of the taxonomic groups we saw in our plasma-free negative control samples have previously been associated with diseases, including ME/CFS, demonstrating how incorrect conclusions may arise if controls are not used and batch effects not accounted for.

Metagenomic investigation of plasma in individuals with ME/CFS highlights the importance of technical controls to elucidate contamination and batch effects, by  Miller RR, Uyaguari-Diaz M, McCabe MN, Montoya V, Gardy JL, Parker S, Steiner T, Hsiao W, Nesbitt MJ, Tang P, Patrick DM, for the CCD Study Group in PLOS One 2 Nov 2016

Which countries conduct ME/CFS research?

Phoenix rising forum post, by HIP, January 2016: Why so little ME/CFS research from France and Germany?

There seems to be little ME/CFS research done in France and Germany, relative to their overall scientific output. Why is this?

Using a rough method, I found that the number of ME/CFS scientific research papers published by each country is the following:

research-by-country

 

France and Germany, along with the UK, are the leading countries in Europe in terms of publishing scientific papers. Yet Germany and France seem to have published very few ME/CFS papers. In fact Norway, a country of just 5 million inhabitants, has produced more ME/CFS papers than France or Germany.

I wonder why this is. Moreover, shouldn’t ME/CFS patients in France and Germany be advocating for more ME/CFS research? These countries are leading forces in science and technology, so it would be good to have them onboard.

The following diagram shows the number of scientific papers (of any sort) published by different countries around the world. As you can see, France and Germany are leading nations in terms of their overall scientific output. Yet they do very little ME/CFS research…

I just modified the search parameters to exclude any UK papers containing the phrases “graded exercise” and “cognitive behavioural therapy”, and with these GET/CBT papers excluded, it brings the UK total number of ME/CFS papers down from 595 to 480.

Similarly for the Netherlands, another country with a lots of psychobabble ME/CFS research, modifying the search to exclude GET/CBT brings to the total number of Dutch ME/CFS papers down from 173 to 112.

FITNET trial reporting is misleading

Major charities and individuals have joined WAMES in expressing concern about the nature of the FITNET trial being run by Prof Esther Crawley, the lack of objective analysis in the media coverage and the questionable results from the original Dutch trial.

WAMES does not support the FITNET trial. We do not believe it is a good use of public money. Patient surveys and poor results from the PACE trial raise questions about the effectiveness (and safety) of CBT and GET in adults. The Dutch trial in children with fatigue did not produce better long term results than usual care and it is unclear whether all participants had strictly defined ME.

WAMES recommends caution for young people with ME participating in the ‘intensive activities’ that the FITNET trial requires, as post-exertional exacerbation of symptoms, is the key characteristic of ME.

ME Association, 1 November 2016: ME Association comments on today’s news reports about the online CBT Trial for children,

THE UNACCEPTABLE FACE OF ME/CFS NEWS COVERAGE

Finally, to return to the BBC press coverage this morning, whilst it was encouraging to note that while it was being stressed on several occasions that ME/CFS has a biological basis/cause, it was completely unacceptable to then find that news bulletin coverage on BBC Radio 2 was then referring to an illness that caused children to miss school and have mental health problems.   Read the full article

Action for ME, 2 Nov 2016: New FITNET trial announced for young people with M.E.
November 02, 2016

There has been considerable media coverage of the trial, which began recruiting yesterday, though results are not expected for a number of years. Some coverage has suggested that M.E. leads to “mental health problems and missing school” (BBC news), which considerably underplays the devastating effects of M.E. on children and young people with the condition and their families.

Nor should the inclusion of a psychological therapy in the trial be taken as evidence that M.E. is psychological in origin. It is not. M.E. is a chronic, fluctuating, neurological condition that causes symptoms affecting many body systems. Research shows that people with M.E. score lower overall on health-related quality of life tests than most other chronic conditions.

Action for M.E. does not recommend or endorse any individual treatments or management approaches for people with M.E., but instead provides key information to empower those affected by M.E. to make informed decisions.

CBT is not a cure for M.E. but some people with M.E. tell us it helps them cope with the impact of the illness. In 2014, we surveyed more than 2,000 people with M.E and our resulting M.E. Time to deliver report showed that 33% of respondents had tried CBT and of these, 54% said they found it helpful or very helpful, 34% said it resulted in no change, and 12% said it made them a bit or much worse. However, almost all of those surveyed were adults.

Sonya Chowdhury, Chief Executive, Action for M.E., says, “Media coverage has repeatedly described 63% of patients being cured in the Dutch study, but this is misleading, and fails to take into account the long-term effects of M.E.”

Additionally, it is important to note that there has been no reference to a follow-up study that was undertaken by the Dutch FITNET team. This found that, at long-term follow-up (an average of 2.7 years), there was no difference between the recovery rates for the different treatment strategies (FITNET versus any form of usual care) although recovery, as reported by the study, was eight times slower for those not using the FITNET treatment strategy. The results of the UK study are unlikely to be published for six years.  Read the full article

Utting-Wolf spouts: PACE part II? Esther Crawley and FITNET

…Costing £1 million, we yet again see large sums of money being spent on studies promoting the biopsychosocial (BPS) model of the disease rather than decent biomedical research. Crawley’s trial draws on a Dutch study which showed no difference between treatment cohorts at long term follow up[2], though the BBC and their scientifically illiterate journalists imaginatively and dishonestly spun this as a 2/3rd cure rate.

Again the laziness and uncritical reporting of any story concerning ME, promoted as usual by the Science Media Centre (SMC), by the UK media is glaring. They even dragged out their old canard, supposed victimisation of the brave researcher (that would be Crawley) by nasty ME activists, said researcher ‘heroically’ carrying on despite abuse from a minority of patients. Such claims were conclusively debunked by the recent First-Tier tribunal Judgement, which ordered the release of the PACE trial data but apparently no one told the BBC.

Today’s coverage of FITNET cannot be treated in isolation and should be compared with earlier reporting of the PACE trial by the British media, which was unfailingly enthusiastic, one-sided and uncritical. Both trials have been strongly promoted by the SMC, whose press releases are repeated more or less verbatim by the media, without any attempt to investigate the accuracy of their claims. This is possible in today’s media due to a combination of laziness, establishment cronyism and a lack of scientific understanding amongst journalists reporting on these issues.

The extensive coverage of studies promoting the BPS model of ME is in stark contrast to the virtual non-reporting of any biomedical research. The failure of the media to cover the recent dismantling of PACE, extensively covered elsewhere but barely mentioned in the UK press, was particularly revealing. One would think there was a media blackout, with such coverage as there was focused more on defending the PACE researchers than exposing their fraudulent study.

Had the media noted the flaws in PACE and the reasoning that underlines such studies so they might have been able to interrogate Crawley regarding the potential flaws in her study. The fact that the participants in the FITNET study will be children, makes it more morally questionable, though her focus on fatigue as the primary symptom suggests many trial subjects probably won’t have ME, as was the case with PACE. No doubt this will flatter her results if/when they are published, not always guaranteed with Crawley as demonstrated by the SMILE trial.

… it has been brought to my attention that James Gallagher, the BBC’s Health Editor who so enthusiastically promoted FITNET, is on the advisory committee of the Science Media Centre that controlled today’s coverage (and pretty much all media reporting relating to ME). I don’t remember his pointing out this potential conflict of interest and I shall be making a formal complaint to the BBC…   Read the full blog post

i news post by Scott Jordan Harris, 1 Nov 2016: CBT won’t cure my chronic fatigue, any more than it would cancer – it’s a physical illness

My CBT helped me immensely in that it gave me mental strategies to cope with the physical limitations of my life. I hope it can help others in the same way. But the idea that CBT is a treatment for ME itself is dangerous and unhelpful.

What ME-sufferers in the UK really need is not talking therapy but well-funded, and properly conducted, biomedical research. And the truth is that, when it comes to ME, Britain is a backwater.

As American medical journalist Miriam E. Tucker tweeted from an international conference on ME in Florida last week: “Striking disconnect between the high-level science here at #IACFSMEConf vs. attitude toward ‘chronic fatigue syndrome’ in the med[ical] community.”    Read more

Epigram, by Emily Faint, 2 Nov 2016: Backlash for ‘landmark’ University research trials

Interestingly, psychologists Trudie Chalder and Peter White, researchers in the PACE trial questioned the results of the original Dutch FITNET trial back in 2012: Chronic fatigue syndrome: treatment without a cause

What were the limitations of the trial? The main difficulty in the interpretation of the impressive out-comes in this trial was to understand the differences between FITNET and usual care. We are given little information about usual care beyond a brief summary of treatments received by participants. This lack of information means that the different outcomes might have been due to differences in dose (number of sessions or contacts), frequency or duration of the interventions, the involvement of parents in FITNET but not usual care, or some other difference that was not measured.

The other main issue is how to define recovery from an illness that includes symptoms that are sometimes reported by healthy people.8 The investigators defined recovery post hoc. However, the criteria used to define recovery were not stringent and some individuals who entered the study were already attending school fairly frequently. The investigators also used liberal criteria, such as the population mean plus two rather than one standard deviation, as their thresholds for recovery by continuous measures such as fatigue.

Therefore, the 63% of patients reported as recovered might have included those who had a significant improvement rather than being fully recovered. This proportion of patients does not detract from the still impressive difference from the 8% of participants who were judged to be recovered after usual care. Read full comment

Fear & avoidance or a desire for participation? a look at PEM

Livets bilder blog post, by Swedish blogger, 29 October 2016: Fear and avoidance or a desire for participation?

A cardinal symptom of ME/CFS is Post-Exertional Malaise (PEM):

“There is an inappropriate loss of physical and mental stamina, rapid muscular and cognitive fatigability, post exertional malaise and/or fatigue and/or pain and a tendency for other associated symptoms within the patient’s cluster of symptoms to worsen. There is a pathologically slow recovery period – usually 24 hours or longer.”

When I talk about cardinal symptoms I mean the main symptoms that must be met for the diagnosis to be set.

For me PEM is something that has been around several years before I got my stressrelated fatigue diagnosis. It has followed the same pattern for nearly a decade although my activity level had varied a lot. From the time where I was working full time but with very limited leisure until now when I am basically home-bound and forced to spend most of my time in my bed or sofa.

Although the clear and recurrent pattern, this is the thing – combined with my extremely limited range of activity – that people in general and health care in particular has had very difficult to understand and accept.

It is clear that most people can understand what it is to feel discomfort in the moment – due to sound, lighting, uncomfortable seating and so on – but they don’t seem to understand the extreme consequences that can appear afterwards. As healthy you can struggle through that “short” moment of discomfort and then it’s okay. I can also put up with the discomfort in the moment, mostly. But my problems does not end when the moment is over. It may even worsen for several days afterwards and then be present for a long time.

So “temporary discomfort” – due to physical, mental or emotional stress – can create an overload and a deterioration due to exertion – that can be long-lasting. But a vigorous exertion in an individual with ME/CFS is also is a risk of a permanent impairment.

If I want to avoid what you see as temporary discomfort, it’s not that I find it difficult to persevere. On the contrary I am often too stubborn to bite the bullet for my own good. No, it’s all about that I know what to expect afterwards, and which the long-term consequences might be.

What seems like a short-term discomfort for a healthy individual thus have far-reaching consequences in my everyday life. This means not only an increase in discomfort and other symptoms, but also that my range of activity shrinks and my already slow pace becomes even slower. It is thus to be even more limited in my daily life I want to avoid.

I do not want to overexert because I want to proceed with what I know I am capable of. To be active even if it is on a low level. To minimize the risk that an already very limited life becomes even more limited. It’s all maintenance, and not at all about fear or avoidance.

When I avoid things, it’s not about fear of increased discomfort in the moment. Nor of post-exertional malaise. No, it is in respect of my body’s limits and a part of a deliberate strategy – that I should be able to continue to be a part of my everyday life.

For me examples of triggers can be fluorescent lighting, waiting while seated, noise etc.
