ME: symptoms & biomarkers

Review abstract:

Myalgic Encephalomyelitis (ME) continues to cause significant morbidity worldwide with an estimated one million cases in the United States. Hurdles to establishing consensus to achieve accurate evaluation of patients with ME continue, fueled by poor agreement
about case definitions, slow progress in development of standardized diagnostic approaches, and issues surrounding research priorities.

Because there are other medical problems, such as early MS and Parkinson’s Disease, which have some similar clinical presentations, it is critical to accurately diagnose ME to make a differential diagnosis.

In this article, we explore and summarize advances in the physiological and neurological approaches to understanding, diagnosing, and treating ME. We identify key areas and approaches to elucidate the core and secondary symptom clusters in ME so as to provide some practical suggestions in evaluation of ME for clinicians and researchers.

This review, therefore, represents a synthesis of key discussions in the literature, and has important implications for a better understanding of ME, its biological markers, and diagnostic criteria. There is a clear need for more longitudinal studies in this
area with larger data sets, which correct for multiple testing.

What matters to children with CFS/ME? devising a PROM

Research abstract:

Background:
Paediatric chronic fatigue syndrome (CFS)/myalgic encephalomyelitis (ME) is relatively common and disabling. Research is hampered because current patient-reported outcome measures (PROMs) do not capture outcomes that are important to children with CFS/ME.

Aim
The aim of this study was to explore the aspects of life and health outcomes that matter to children with CFS/ME.

Methods
Twenty-five children with CFS/ME were interviewed (11 males, 14 females; mean age 12.9 years (SD 2.2), range 8-17). Twelve were trial participants interviewed during the trial and 13 were recruited as part of a follow-up qualitative study.

Parents were present in 19 interviews with their children. Three mothers participated in a focus group. All the interviews and the focus group were audio-recorded and transcribed. Data were analysed thematically using techniques of constant comparison. NVivo was used to structure and categorise data in a systematic way.

Results
Children identified four key themes (health outcome domains):  ‘symptoms’ that fluctuated, which caused an unpredictable reduction in both ‘physical activity’ and ‘social participation’ all of which impacted on ’emotional well-being’.

These domains were influenced by both ‘management’ and ‘contextual factors’, which could be positive  and negative. The relationship between healthcare and school was
considered pivotal.

Conclusions
Children’s descriptions helped to inform a conceptual model that is necessary to develop a new paediatric CFS/ME PROM. Doctors need to be aware of how children conceptualise CFS/ME; the relationship between healthcare and school is fundamental to ameliorate the impact of CFS/ME.

Association between cognitive performance & pain in CFS

Research abstract:

BACKGROUND: In addition to the frequently reported pain complaints, performance-based cognitive capabilities in patients with chronic fatigue syndrome (CFS) with and without comorbid fibromyalgia (FM) are significantly worse than those of healthy controls. In various chronic pain populations, cognitive impairments are known to be related to pain severity. However, to the best of our knowledge, the association between cognitive performance and experimental pain measurements has never been examined in CFS patients.

OBJECTIVES: This study aimed to examine the association between cognitive performance and self-reported as well as experimental pain measurements in CFS patients with and without FM.

STUDY DESIGN: Observational study.

SETTING: The present study took place at the Vrije Universiteit Brussel and the University of Antwerp.

METHODS: Forty-eight (18 CFS-only and 30 CFS+FM) patients and 30 healthy controls were studied. Participants first completed 3 performance-based cognitive tests designed to assess selective and sustained attention, cognitive inhibition, and working memory capacity. Seven days later, experimental pain measurements (pressure pain thresholds [PPT], temporal summation [TS], and conditioned pain modulation [CPM]) took place and participants were asked to fill out 3 questionnaires to assess self-reported pain, fatigue, and depressive symptoms.

RESULTS: In the CFS+FM group, the capacity of pain inhibition was significantly associated with cognitive inhibition. Self-reported pain was significantly associated with simple reaction time in CFS-only patients. The CFS+FM but not the CFS-only group showed a significantly lower PPT and enhanced TS compared with controls.

LIMITATIONS: The cross-sectional nature of this study does not allow for inferences of causation.

CONCLUSIONS: The results underline disease heterogeneity in CFS by indicating that a measure of endogenous pain inhibition might be a significant predictor of cognitive functioning in CFS patients with FM, while self-reported pain appears more appropriate to predict cognitive functioning in CFS patients without FM.

Do people with ME and CFS really recover?

The Recovery Question, by Dan Neuffer in Health Rising Forum, Sep 17 2015

There is much information out there on how to diagnose Fibromyalgia Syndrome (FMS) or Chronic Fatigue Syndrome (CFS) (also described as Myalgic Encephalomyelitis or ME). And whilst a diagnosis can be elusive for many people suffering with this illness, there is certainly no doubt that they are very ill, even if their doctors, family or friends don’t always share this certainty.
But there is little talk about recovery; how to identify if you have fully recovered from Fibromyalgia or ME/CFS. Why? Possibly because many people including doctors may believe that recovery isn’t possible – or at least not for them or for their patients. After my 4th year of trying to get well again, I certainly myself came to that conclusion and had given up hope.

But in recent years, numerous recovery stories have popped up on the internet. (See Recovery Stories section on Health Rising and CFS Unravelled). However some people believe, probably based on their hard-won experience, that recovery from ME/CFS or fibromyalgia is impossible. In other words, if you recovered from it you never had it in the first place.

Having recovered myself after over 6 years of illness, which at times was very severe, I understand but no longer share this belief. Since my recovery I have spoken with many other people that recovered, some who did so even after decades of illness which has strengthened my belief in recovery beyond my own experience. But of course, not everyone is easily convinced by hearing recovery stories, and for several reasons.

  • I suspect that many “recoveries” may be little more than symptom suppression and management
  • It’s not exactly clear what “recovery” is
  • That recovery can occur in a wide variety of ways is confusing

Recovery vs Cure vs Remission

The dictionary states that

  • A cure is the end of a medical condition; the substance or procedure that ends the medical condition, such as a medication, a surgical operation, a change in lifestyle, or even a philosophical mindset that helps end a person’s sufferings. It may also refer to the state of being healed, or cured.
  • A remission is a temporary end to the medical signs and symptoms of an incurable disease. A disease is said to be incurable if there is always a chance of the patient relapsing, no matter how long the patient has been in remission.

So cure is an “end” of a medical condition which implies that there is no chance of the patient relapsing. That raises the question of whether there are cures for chronic illnesses? In fact most if not all chronic illnesses are managed not cured. Cancer, heart disease, depression, MS, ALD, AIDS, diabetes, the list is nearly endless – can be managed by medication, lifestyle, diet, etc. – but are rarely cured. That suggests that in general with regard to chronic illnesses, the word cure may a misnomer.

Perhaps the word cure also suggests a single treatment or therapy that works the same for everyone with little room for tailoring treatment. Since no such “cure” is known for Fibromyalgia and Chronic Fatigue Syndrome (Myalgic Encephalomyelitis) perhaps remission is more appropriate term to use for those who have regained their health. But that word suggests that their period of wellness may be temporary, that at some point they will or may have a chance of getting sick again. We know this is true, of course, and a survey on Health Rising supports this, but such negative connotations don’t necessarily serve those that regained their health, nor do they set up great expectations for those still working to restore their health.

That’s why my preference is for the word recovery. A recovery is a restoration of health or functioning and can be either partial or full. It goes beyond stopping the underlying disease mechanism – which a cure does. Even people who get “cured” from a disease, still need to make a recovery.

What Constitutes a Recovery From Fibromyalgia/ME/CFS?

I have come across people who explain how they take dozens of supplements, regular IV infusions, hormone treatment and so on, in order functioning fairly normally again. But I ask, if you’re managing or reducing your symptoms using a range of medications, hormones and supplements to something that resembles normal health – is that recovery? I would say no. I would say those people are managing their illness using orthomolecular or some other branch of medicine but they are not recovered.

Some people are able to very significantly reduce their symptoms by limiting their physical and mental activity. By avoiding stress, eating the “perfect diet” and staying inside a limited physical activity envelope their symptoms are much reduced or sometimes gone. They feel healthy. Others can participate in most aspects of life – except for rigorous exercise. I think these are cases of improvement – sometimes very significant improvement – but not recovery.

To me, a recovery means that your body’s function is restored enough to allow it to cope with the normal activities associated with full-time work and an active lifestyle that includes doing social activities and exercise, as well as eating a normal diet (normal not meaning good!). Even here, though, there are levels.

I remember when I first felt recovered. My flare ups had ceased and I no longer had pain, fever, insomnia, gut dysfunction or brain fog. But other symptoms were trickier and more difficult to quantify. Whilst I had thought my energy and immune function had returned to normal, a year later, I noticed that my energy levels were still increasing and that my health felt even more robust.

So although I previously thought I had fully recovered, I clearly had not. My reference point regarding what was “normal” health, had clearly shifted during my years with ME/CFS/Fibromyalgia.

In my mind recovery of health has to be about your body functioning well and giving you access to the experience of good health without being reliant on external powerful drugs or severe lifestyle restrictions.

Does Recovery Occur?

Given that definition of recovery – have people fully recovered from this illness? The recovery stories suggest yes and while recovery may not be common it may be happen more often than we think. I have interviewed over 40 people that recovered and met around 200 personally. Given the lack of study in this area, the percentage of people who make full recoveries is impossible to say.

It’s at this point that some skepticism naturally emerges. I was skeptical myself, pathologically so in my later years of suffering with ME/CFS and Fibromyalgia. I, too, had unsuccessfully tried many of the things people had used to recover from. (In fact, some of those things later worked for me.) Anyone who has experienced a bleeding wallet thanks to never-ending tests, treatments and empty promises will inevitably adopt a bit of healthy skepticism.

For people that have tried many things, including the things those other people used to get well, but despite all that have still not recovered, I understand the frustration. I understand why they might assert that “They  didn’t have what I have”. For most of us, most symptom treatments simply do not lead to recovery.

To Have Had ME/CFS/FM or ME or Not?

But can those people go further and say the people who recovered didn’t have ME/CFS/FM or ME?

When people make a full recovery and people say that they never had the illness or had something else, that is too far in my view. There are undoubtedly varying degrees of illness and different secondary dysfunctions that form the syndrome, but suggesting that someone didn’t have the illness based on the fact they got their health back, does not seem very scientific.

If you look at the symptoms and experience of many people that claim recovery, you can see that many were significantly ill. Almost all, for instance, had to quit working. Some became bedridden and many became largely homebound. Many spent years searching for something that might help. Some were ill for decades.

The different treatments used can raise questions as well. People, after all, have recovered in all sorts of ways. I think most people would agree that a person who recovered using antivirals had ME/CFS or ME. But what if “less powerful” treatments worked? What if supplements and herbs in conjunction with pacing made the difference? What if mind/body work played a large role? Or if diet or strict pacing did? Or a combination of “softer” treatments did? People diagnosed with ME/CFS/FM who have had very significant illness have recovered using all these approaches. Does the type of treatment used determine what kind of illness someone had?

Then there are people’s “accidental” recoveries: people who don’t know WHY they recovered. Can you recover from a serious chronic illness without knowing why? My experience and discussions with people says yes. I imagine we looked hard enough in the literature or talked to a doctor you would find cases of people who had recovered from many chronic illnesses where no one was exactly sure why.

Did all these people that claim to have recovered from “ME” or “ME/CFS” or “Fibromyalgia” actually have it? I think it makes sense to look at the details. Both fatigue and chronic pain are often used to define the illness, but we know there are other reasons for such symptoms, even if they are chronic. But I believe that people who had the RANGE of symptoms we associate with this SYNDROME, who saw doctors and tried to get well and whose illness persisted, I believe that they truly had the illness – as we know it now.

So many of us have been frustrated by the need to ‘prove’ our invisible illness with the medical community, our family and our friends. It’s ironic that some of those same people now have to prove they had ME/CFS/FM at all – simply because they got well.

ACT (Acceptance and commitment therapy) for CFS

Research abstract:

Acceptance is understood to be an important element in coping and  living with chronic illnesses such as diabetes and chronic pain, and increasing acceptance has been related to a number of positive  outcomes such as reduced symptoms as well as greater reported quality  of life.

Chronic Fatigue Syndrome (CFS) is a disabling disorder that is associated with poor reported quality of life even in comparison to others chronic conditions.

Given that ACT (Acceptance and commitment therapy) is a psychotherapeutic model aimed at increasing psychological flexibility and values pursuance, the approach holds potential for coping and living with CFS, with interesting implications for service provision and client care.

We utilized a six-week guided self-help ACT intervention with six detailed case studies to assess the utility of an ACT self-help intervention for this under-researched population, and whether any therapeutic and physical change is driven by predicted ACT mechanisms.

These results are discussed in relation to ACT processes and implications for working with individuals with a diagnosis of CFS.

Effect on siblings of children with CFS/ME

Research abstract:

Chronic fatigue syndrome or myalgic encephalomyelitis (CFS/ME) is a disabling condition known to have a negative impact on all aspects of a child’s life. However, little is understood about the impact of CFS/ME on siblings.

A total of 34 siblings completed questionnaires measuring depression (Hospital Anxiety and Depression Scale (HADS)), anxiety (HADS and Spence Children’s Anxiety Scale (SCAS)) and European Quality-of-life-Youth (EQ-5D-Y). These scores were compared with scores from normative samples.

Siblings had higher levels of anxiety on the SCAS than adolescents of the same age recruited from a normative sample; however, depression and quality-of-life were similar.

Interviews were undertaken with nine siblings of children with CFS/ME who returned questionnaires. Interview data were analysed using a framework approach to thematic analysis. Siblings identified restrictions on family life, ‘not knowing’ and lack of communication as negative impacts on their family, and change of role/focus, emotional reactions and social stigma as negative impacts on themselves. They also described positive communication, social support and extra activities as protective factors.

Paediatric services should be aware of the impact of CFS/ME on the siblings of children with CFS/ME, understand the importance of assessing paediatric CFS/ME patients within the context of their family and consider providing information for siblings about CFS/ME.

Low NK cell activity differs in ME/CFS & MS

Research abstract:

Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) and Multiple Sclerosis (MS) patients suffer from debilitating fatigue which is not alleviated by rest. In addition to the fatigue related symptoms suffered by CFS/ME and MS patients, dysfunction of the immune system and in particular, reduced Natural Killer (NK) cell cytotoxic activity has also been reported in CFS/ME and MS.

The purpose of this pilot study was to compare NK cellular mechanisms in CFS/ME and MS patients to investigate potential dysfunctions in the NK cell activity pathway. Flow cytometry protocols assessed CD56dim CD16+ and CD56bright CD16+/- NK cell expression of adhesion molecules, NK activating and inhibiting receptors, NK cell maturation and lytic proteins.

All participants in this study were female and included 14 CFS/ME patients, 9 MS patients and 19 non-fatigued controls. The patient groups and the non-fatigued controls were not taking any immunosuppressive or immune enhancing medications.

In the MS cohort, KIR2DL5 was significantly increased on CD56bright CD16+/- NK cells and expression of CD94 was significantly increased on CD56dim CD16+ NK cells in comparison to the controls. Co-expression of CD57 and perforin was significantly increased on CD56dim CD16+ NK cells from CFS/ME patients compared to the MS and non-fatigued control participants.

The results from this pilot study suggest that NK cells from CFS/ME and MS patients may have undergone increased differentiation in response to external stimuli which may affect different mechanisms in the NK cell cytotoxic activity pathway.
