What Primary Care Practitioners Need to Know about the New NICE Guideline for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome in Adults

Abstract:

The new NICE guideline for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), published in October 2021, makes significant changes in treatment recommendations. It acknowledges the complexity of this chronic medical condition, which always impacts quality of life and can be profoundly disabling, recognising the prejudice and stigma that people with ME/CFS often experience in the absence of any specific diagnostic test.

The guideline outlines steps for accurate diagnosis, recognising post-exertional malaise as a core symptom; importantly, ME/CFS can now be diagnosed after just 3 months in a bid to improve long-term health outcomes. It recommends the need for individual, tailored management by a multi-disciplinary team, ensuring that the wellbeing of the individual is paramount. The guideline makes clear that any programme based on fixed incremental increases in physical activity or exercise, for example graded exercise therapy (GET), should not be offered as a treatment for ME/CFS and emphasises that cognitive behavioural therapy (CBT) should only be offered as a supportive intervention.

Because of the rigorous methodology required by NICE Committee review and the inclusion of the testimony of people with lived experience as committee members, this guideline will influence the future diagnosis and management of ME/CFS in the UK and beyond.

DecodeME: community recruitment for a large genetics study of myalgic encephalomyelitis / chronic fatigue syndrome

Abstract:

Background: Myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS) is a common, long-term condition characterised by post-exertional malaise, often with fatigue that is not significantly relieved by rest. ME/CFS has no confirmed diagnostic test or effective treatment and we lack knowledge of its causes. Identification of genes and cellular processes whose disruption adds to ME/CFS risk is a necessary first step towards development of effective therapy.

Methods: Here we describe DecodeME, an ongoing study co-produced by people with lived experience of ME/CFS and scientists. Together we designed the study and obtained funding and are now recruiting up to 25,000 people in the UK with a clinical diagnosis of ME/CFS. Those eligible for the study are at least 16 years old, pass international study criteria, and lack any alternative diagnoses that can result in chronic fatigue. These will include 5,000 people whose ME/CFS diagnosis was a consequence of SARS-CoV-2 infection. Questionnaires are completed online or on paper. Participants’ saliva DNA samples are acquired by post, which improves participation by more severely-affected individuals. Digital marketing and social media approaches resulted in 29,000 people with ME/CFS in the UK pre-registering their interest in participating. We will perform a genome-wide association study, comparing participants’ genotypes with those from UK Biobank as controls. This should generate hypotheses regarding the genes, mechanisms and cell types contributing to ME/CFS disease aetiology.

Discussion: The DecodeME study has been reviewed and given a favourable opinion by the North West – Liverpool Central Research Ethics Committee (21/NW/0169). Relevant documents will be available online ( www.decodeme.org.uk ). Genetic data will be disseminated as associated variants and genomic intervals, and as summary statistics. Results will be reported on the DecodeME website and via open access publications.

ME/CFS: Exercise goals should be set by patients and not driven by treatment plan, says NICE

Letter:

Rapid Response:

Patient reports of harm from GET cannot be ignored

Dear Editor

Professor Trudie Chalder from King’s College Hospital states that:

“The NICE guidelines for CFS/ME are at odds with the research evidence. Researchers from different institutions in different countries have found graded exercise therapy and cognitive behaviour therapy to be effective for some patients with CFS.

Evidence has shown they reduce fatigue and improve functioning without harm, if delivered by trained therapists in specialist clinics. Being a clinician and researcher in this field, I can’t help but think clinicians will be confused by this message from a respected organisation.”

Having carefully reviewed all the very extensive evidence on efficacy and safety for graded exercise therapy (GET) from relevant clinical trials, medical experts and from people with ME/CFS, the NICE guideline committee concluded that in addition to there being no sound evidence for efficacy for GET there was also consistent patient evidence of harm, sometimes serious and persisting, occurring.

Charities, patients, and researchers are working together to find the cause and effective treatments for ME/CFS

People with ME/CFS feel let down by the medical establishment because almost all biomedical research until recently has been funded by the charity sector. Almost all government funding has gone into research based on a flawed psychosocial model of causation involving abnormal beliefs and behaviours and deconditioning. This research resulted in the current NICE guideline recommendations, published in 2007, for cognitive behavioural therapy (CBT) and graded exercise therapy (GET).3

Having reviewed clinical trial and patient evidence for these interventions,4 NICE now states in the introduction to the draft of its updated guideline on ME/CFS5 that “because of the harms reported by people with ME/CFS, as well as the committee’s own experience of the effects when people exceed their energy limits, the draft guideline says that any programme based on fixed incremental increases in physical activity or exercise, for example graded exercise therapy (GET), should not be offered for the treatment of ME/CFS.” It also emphasises that CBT is not a treatment or cure for ME/CFS.

MEA Review: Grey and white matter differences in chronic fatigue syndrome

The ME Association of Great Britain has provided an excellent review of a recent study on brain matter abnormalities in ME/CFS patients. The study, Grey and white matter differences in Chronic Fatigue Syndrome – A voxel-based morphometry study, was conducted by Julia Newton’s group at Newcastle University. Below is an excerpt from Dr. Shepherd’s summary of the study. To read a full discussion, along with an excellent overview of brain pathology and the implications of these brain abnormalities, go HERE. You can download the full review as a PDF file.

Comment from Dr Charles Shepherd, Hon Medical Adviser, ME Association:

This study was carried out in Newcastle by Professor Julia Newton and colleagues – a team who have not only achieved a long and distinguished record in ME/CFS research but also have access to patients who have been very carefully assessed from a clinical point of view. So, the results should be taken seriously.

As has been pointed out in this review, three of the main criticisms of previous neuroimaging studies involving people with ME/CFS is that the numbers involved have often been far too small; there has been a lack of information from other control groups that would be relevant in addition to the use of healthy controls; and that different imaging techniques have been used.  So, not surprisingly, the results are not always consistent.

Despite these caveats, these results clearly add weight to the findings from previous neuroimaging studies describing white matter abnormalities in ME/CFS but also raise the possibility of grey matter involvement in ME/CFS.

There are several possible explanations for these findings but no clear answer has emerged in the paper.  Are they a primary feature of ME/CFS?  Or are they secondary to other factors – e.g. duration of illness, decrease in activity, severity of fatigue – that are related to having ME/CFS?  The only way to find out is through further research into what is clearly an interesting aspect of neuropathology in ME/CFS.

A fully referenced summary of all the key findings from both functional and structural neuroimaging studies in ME/CFS can be found in the Research section of the ME Association ‘An Exploration of the Key Clinical Issues’ available from our online shop.

PACE trial claims for recovery in myalgic encephalomyelitis/chronic fatigue syndrome – true or false? It’s time for an independent review of the methodology and results

Abstract:

The PACE trial set out to discover whether cognitive behaviour therapy and graded exercise therapy are safe and effective forms of treatment for myalgic encephalomyelitis/chronic fatigue syndrome. It concluded that these interventions could even result in recovery. However, patient evidence has repeatedly found that cognitive behaviour therapy is ineffective and graded exercise therapy can make the condition worse. The PACE trial methodology has been heavily criticised by clinicians, academics and patients. A re-analysis of the data has cast serious doubts on the recovery rates being claimed. The trust of patients has been lost. The medical profession must start listening to people with myalgic encephalomyelitis/chronic fatigue syndrome if trust is going to be restored.

Exploring the feasibility of establishing a disease-specific post-mortem tissue bank in the UK: a case study in ME/CFS

Abstract:

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a condition, the aetiology of which remains controversial, and there is still no consensus on its nature and determination. It has rarely been studied in post-mortem examinations, despite increasing evidence of abnormalities from neuroimaging studies.

AIM: To ascertain the feasibility of developing a national post-mortem ME/CFS tissue bank in the UK, to enhance studies on aetiology and pathogenesis, including cell and tissue abnormalities associated with the condition.

METHODS: The case study was carried out combining qualitative methods, ie, key informant interviews, focus group discussions with people with ME/CFS, and a workshop with experts in ME/CFS or in tissue banking.

RESULTS AND CONCLUSIONS: The study results suggest that the establishment of the post-mortem ME/CFS tissue bank is both desirable and feasible, and would be acceptable to the possible tissue donors, provided that some issues were explicitly addressed.

NICE behaviour: ME guideline is unworkable

Comment on: Diagnosis and management of chronic fatigue syndrome or myalgic encephalomyelitis (or encephalopathy): summary of NICE guidance. [BMJ. 2007]

 

The National Institute for Health and Clinical Excellence (NICE) recommends that everyone with mild or moderate myalgic encephalopathy/chronic fatigue syndrome (ME/CFS) should be offered a course of either cognitive behaviour therapy (CBT) or graded exercise therapy (GET).1

This is despite published evidence remaining weak (especially for group CBT) and inconsistent 2. Patient evidence submitted to the chief medical officer’s report concluded that CBT produced “no change” in 67% of cases and made the condition “worse” in 26% of cases.3 Around 50% of respondents reported that inappropriate exercise therapy had also made their condition “worse.”3

When the NICE estimate on prevalence is used this controversial recommendation will affect some 200 000 people. A one to one course of CBT covering 12 to 16 sessions will cost well over £1500. The cost of a professionally supervised exercise therapy programme is also likely to be substantial.

So where is around £300 million of new money going to come from at a time when very limited funding for some of the newly established NHS clinical services for people with ME/CFS is now being cut?4 And where are all the therapists going to come from? Those already in post often cannot even cope with their current workload.

These are important questions that I raised at a NICE implementation and planning meeting in October 2006—but nobody from NICE could provide a convincing answer. These recommendations are going to be of no value whatsoever to many people with ME/CFS. They are also going to be impossible to implement owing to a lack of both funding and human resources.

The debate: myalgic encephalomyelitis and chronic fatigue syndrome

Abstract:

Almost every aspect of myalgic encephalomyelitis (or encephalopathy) and chronic fatigue syndrome is the subject of disagreement and uncertainty — something that has undoubtedly hampered recognition, understanding and research. Although the pathogenesis remains the subject of intense medical debate, a number of predisposing, precipitating and perpetuating factors are now starting to emerge. Therapeutic nihilism is no longer appropriate as there is a great deal that can be done to alleviate some of the more distressing symptoms and improve quality of life for these patients.

Patients with chronic fatigue syndrome are being ignored

Comment on: What causes chronic fatigue syndrome? [BMJ. 2004]

 

Editor—Earlier this year more than 28, 000 people signed a petition calling for urgent government funded research into the physical causes of myalgic encephalomyelitis and chronic fatigue syndrome. Such is the frustration of people who do not believe that their views are being listened to by the medical establishment.

So White’s editorial reviewing the possible causes of myalgic encephalomyelitis and chronic fatigue syndrome should be welcome news.1 But is it?

Many doctors support the idea of a disease model with predisposing, precipitating, and perpetuating factors. However, White does not offer any innovative suggestions as to how this could be used to better understand an illness that now covers a wide variety of clinical presentations and an equally diverse range of patho-physiological findings. Having created this mess, the medical profession must now accept that this heterogeneous group of patients is unlikely to have the same pathoaetiology and respond to the same form of treatment, be it pharmacological or behavioural.

What is needed is thought provoking research that dispenses with the oversimplistic view that myalgic encephalomyelitis and chronic fatigue syndrome entail little more than a vicious circle of abnormal illness beliefs and behaviour, inactivity, and deconditioning. The World Health Organization now classifies both myalgic encephalomyelitis and chronic fatigue syndrome as neurological disorders in section G93.3 of ICD-10. The time has come to look at the neurology of central fatigue—instead of pouring yet more money into the bottomless pit of psychological research.
