Continuing to use the Oxford definition (of ME/CFS) may impair progress and cause harm. National Institutes of Health Pathways to Prevention Workshop: Advancing the Research of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome draft statement
The United States National Institutes of Health (NIH) has issued a draft report that highlights the dire need for scientific research that will help find a cure for the millions of people suffering from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) worldwide. The report also highlights the fact that the decades-old UK Royal Society of Medicine’s Oxford criteria for ME/CFS are severely “flawed,” and that continuing to use these criteria may “cause harm.” Further, the NIH report says that the Royal Society definition should “be retired” and replaced with a single case definition agreed to by the ME/CFS community.
These statements were made in a draft summary of a short multidisciplinary Pathways to Prevention Workshop co-sponsored by the NIH and Trans-NIH Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) Research Working Group mid December, and attended by experts and interested persons. It was posted on the NIH Office of Disease Prevention (ODP) website for public comment; and a final report is expected in a few weeks time.
While the draft report does not mention the hugely controversial UK Medical Research Council (MRC) PACE (adaptive Pacing, graded Activity and Cognitive behaviour therapy; a randomized Evaluation) study trials, it effectively discredits the trials because they were based on these Oxford Criteria.
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is Misunderstood and Often Misdiagnosed
The lack of a consistent, specific, sensitive diagnostic test and set of criteria has hampered all downstream research on pathogenesis and treatment, causing harm and preventing ME/CFS from being considered as a distinct pathologic entity. NIH draft report
There is absolutely no doubt that medical research has failed the ME/CFS community.
Identified in the NIH draft report as “a chronic, complex, multi-faceted condition characterized by extreme fatigue and other symptoms that are not improved by rest,” there are no known cures; knowledge about the disease is limited; and a lack of research funding has created “an additional burden for patients and health care providers.”
ME/CFS is an unmet public health need with an economic burden estimated to be greater than $1-billion. NIH draft report
Problems and issues that motivated the Pathways to Prevention Workshop include:
- Multiple case definitions that confuse the issue
- The effectiveness (or otherwise) of current measurement tools used to identify subsets of patients
- The need to use effective research to increase understanding of the “underlying pathology” of ME/CFS
- A desire to identify innovative research approaches that add understanding of ME/CFS and use this knowledge to help develop safe and effective treatments
Above all else, the workshop confirmed, yet again, that “ME/CFS exists.” In spite of the fact that there is still not a clear definition of the illness (or illnesses), there is acknowledgement that it overlaps other diseases, including fibromyalgia. But there is zero agreement in terms of research, prevention, treatment, or anything else.
We heard throughout the workshop that ME/CFS can affect anyone. Education, financial security, and social standing will not prevent the disease. NIH draft report
The draft report published by the NIH shows very clearly that people suffering from so-called ME/CFS come from all walks of life. There is absolutely no data available to indicate who – if anyone – is more (or less) at risk.
The report states that while “fatigue” has been a focus in recent research projects, there are many other symptoms that should be explored. These include “brain fog” (more correctly referred to as neurocognitive deficit), pain, and post-exertion malaise. As the it points out, ME/CFS patients are often labeled “lazy, deconditioned, and disability-seeking,” and this causes medical professionals to treat their ME/CFS patients with “disdain, suspicion, and disrespect.”
A horrifying reality highlighted by the NIH report is that because of this: “Patients are frequently treated with psychiatric and other inappropriate drugs that may cause harm.”
Other revelations include the fact that over the past two decades, very little progress has been made to “improve the state of the science for patients with ME/CFS” (though these very patients know this to be true – they don’t need revelations).
“Patients want their concerns to be heard, a meaningful recovery (not just incremental improvement), and a cure. Educational efforts are needed to help patients and their health care providers better understand this disease and scientific processes. The scientific community also has a responsibility to address issues that are meaningful to patients.”
As it stands, treatments that are offered are completely “unproven,” and it is agreed (at very least by those attending the NIH workshop) that clinical studies have achieved virtually nothing. For instance, while depression (a psychological repercussion) often follows ME/CFS, this is not considered to be a psychological disease and the popular focus on fatigue alone probably doesn’t identify many cases of ME/CFS. As the draft report states, this is a very complex condition and research has a long way to go.
Small, poor-quality studies and a lack of a gold standard for diagnosis and treatment of ME/CFS has led to confusion. NIH draft report
The over-riding feeling in the workshop was, according to the draft report, that very little attention is given to self-management that can empower ME/CFS patients and help them improve their health. This appeared to be largely due to inadequate training of physicians. It was also found that focus on exercise programs further discouraged and stigmatized participation in research. According to the draft report, guidance and a lack of instructions for GET often caused more suffering and a fear that participants would harm themselves by participating in some type of physical activity even if it was only “mild stretching”.
Sadly, it was reported that a lot of ME/CFS patients have been treated “erroneously” and misdiagnosed – and then given “potentially toxic therapies” that are often harmful and end up diminishing all hope.
As the report states, there are a lot of questions that need to be answered. While those participating learned quite a lot about the mechanisms of the disease, because it is “a chronic, complex condition” that has no known cause and absolutely no cure, nothing that came out of the workshop can improve the lives of patients.
Overall, there has been a failure to implement what we already know for patients with ME/CFS while it steals their health and well-being. However, scientifically rigorous research is needed. NIH draft report
The recommendations made in the draft report are far reaching and once the final report is released in a few weeks time, more might be known in terms of what may be ultimately be done to achieve its proposed strategies.
The PACE Trial Study Implies Psychosis of CFS Patients
Since the PACE Trial study results were first released four years ago, The Lancet Psychiatry has published no less than six reports each focusing on a different element of the results. The most recent was published online this week, stating that because ME/CFS patients have “fear avoidance beliefs,” exercise negatively impacts on their symptoms, severely reducing their chances of recovery.
ME Research UK has slammed The Lancet Psychiatry report calling it complicated, misleading, inappropriate and ultimately absurd.
“The data suggests that CFS patients without a comorbid psychiatric disorder do not have an exercise phobia. Prof. Peter White, a co-author of the PACE Trials report.
Carried out from March 2005 till November 2008, the PACE study set out to prove that when cognitive behaviour therapy (CBT) or graded exercise therapy (GET) were combined with specialist medical care (SMC) the physical function of CFS patients was improved and fatigue was reduced when compared to SMC on its own, or SMC combined with adaptive pacing therapy (APT). Further, their stated objective was “to test whether patients with chronic fatigue syndrome (CFS) have an exercise phobia, by measuring anxiety-related physiological and psychological reactions to ordinary activity and exercise.”
Their conclusion quoted above indicates that only those CFS patients who did not have an additional psychiatric disorder, did not exhibit “exercise phobia.” Further, White maintains that both CBT and GET “can safely help a significant number of patients.” This in spite of the fact that the original data provided by the PACE trial showed that only 10 to 15 percent of ME/CFS patients were positively affected.
If you talk to people suffering from CFS you’ll quickly discover that exercise frequently triggers intensified symptoms of this misunderstood disease. Furthermore, many of those suffering from CFS are unable to even conquer normal physical activity; for some even getting out of bed is an enormous effort. So for anyone to imply that their condition is in any way psychological is unspeakable.
The US Centers for Disease Control and Prevention (CDC) puts it in a nutshell.
For patients with CFS, learning to manage activity levels is a key part of managing the illness. This requires a new way of defining exercise and thinking about daily activities. Daily chores and activities, such as cleaning, errands, and hygiene, may need to be broken down into shorter, less strenuous pieces. While vigorous aerobic exercise is beneficial for many chronic illnesses, CFS patients can’t tolerate traditional exercise routines. Exercise programs aimed at increasing aerobic capacity are not recommended early in therapy. CDC
The question on the lips of many people now is, Can we move forward? Will the NIH join forces with the people involved in its Pathways to Prevention Workshop. And together can they make a difference?
