What the
Experts say about ME/CFS
Margaret
Williams 28th March 2006
(It may not be too late to
bring the experts’ views recorded below to the attention of members of the
Gibson Parliamentary Inquiry, a vital step if the scandal of ME/CFS in the UK
is to be halted)
The “Invest in ME” Newsletter of
27th March 2006 (to which acknowledgement is made) reported on the
Presentation given on 18th February 2006 at Denmead,
Hampshire, by Dr Vance Spence, Chairman of the UK ME research charity
MERGE. Quotations from that Newsletter
include the following:
“One important role of MERGE is
to bring the possibility of researching ME/CFS to the attention of scientific
researchers, no easy task for an illness that is so often wrongly referred to
as ‘psychosocial’ ”.
“There are two main ways
that biomedical research gets funded: government and charities. While there are
many general medical charities such as the Wellcome
Foundation and the Nuffield Foundation, none has funded biomedical research
(into ME/CFS)”.
“The MRC has £400 million per
annum (and) the psychological lobby has received an awful lot of funding from
the government. Psychological research
has a role in human health but it is not going to help patients with severe
neurological ME”.
“Biological research into ME/CFS
is ignored by the medical publications”.
“In the UK, there are five times
more people with ME than with HIV AIDS, for which the government provided
ring-fenced money for research, but they have provided nothing for ME
biomedical research”.
In March 2006 the CFIDS
Association of America produced a special 65 page issue of its Chronicle (The
Science and Research of CFS), which refers to “the quiet devastation” and
“ravages” of (ME)CFS.
Contributors include respected researchers and clinicians from across
the world with expertise in ME/CFS.
Few busy doctors or Members of
Parliament, however kindly disposed towards those with ME/CFS, will have time to
read this important document for themselves, so here are some illustrations:
From “The State of
(ME)CFS Research” by Professor Nancy Klimas from the University of Miami Medical School
“Over the past 18 years,
the field has grown in both the number of researchers and disciplines
represented (but) each research finding seems to raise more questions than it
answers. (ME)CFS is a complex
multi-system illness that has eluded easy answers. Unfortunately we still don’t have a lab test
or other diagnostic tool for (ME)CFS. The resulting lack of credibility accorded to
(ME)CFS has been a significant barrier to research and
understanding”.
“We need more research to
understand the various subgroups of CFS and to discover treatments that address
the true biologic underpinnings of this illness. We need to educate health care professionals
about this illness and keep at it until every doctor (and) nurse can quote the
diagnostic criteria”.
“We know that (ME)CFS has
identifiable biologic underpinnings because we now have research documenting a
number of underlying pathophysiologic processes
involving the brain, the immune system, the neuroendocrine
system and the autonomic nervous system”.
From “Across the Pond” by Brigitta
Evengard from The Karolinska
Institute, Stockholm, Sweden
“Researchers in centres
across the world are investigating everything from cause to cure. (ME)CFS is a disease that affects people in
every corner of the world”.
Despite recent
ill-informed assertions from those who support the psychiatric lobby that the
disorder is unknown outside the “cultural” beliefs held in the developed
countries of Europe, the Special Issue documents a small sample of research
centres in countries that include Australia, Belgium, Canada, China, Denmark,
Germany, Iceland, India, Japan, Korea, The Netherlands, Sweden, Spain and the
UK.
From “The Link between
Advocacy and Research”
by Thomas F Sheridan
“The Centres for Disease
Control’s current Director, Dr Julie Gerberding, has
continued to give (ME)CFS personal attention. In June 2004 she stated: ‘(ME)CFS is an important and disabling condition and we must do
more to help the public and health care providers understand its devastating
impact’ ”.
The Epidemiology section by
Professor Leonard Jason et al provides international prevalence estimates:
some examples include Japan (1,500 cases per 100,000); Hong Kong (3,000 cases
per 100,000); Australia (1,500 cases per 100,000); New Zealand (127 cases per
100,000); Brazil (2,000 cases per 100,000); Netherlands (112 cases per 100,000)
and Italy (9,500 cases per 100,000). The
UK figures vary so widely that they are of little value, varying from 130 cases
per 100,000 to 2,600 cases per 100,000, the latter figure coming from Wessely
et al in 1997. According to the CDC, as many as 900,000 Americans have (ME)CFS.
(To put this in a UK perspective:
130 cases per 100,000 equates to 78,000 people out of the UK population of 60
million and 2,600 cases per 100,000 equates to 1,560,000 out of the UK
population of 60 million; by comparison, 83,000 people out of the UK population
of 60 million suffer from multiple sclerosis, which is 139 cases per 100,000).
Jason states: “(ME)CFS is characterised by a pattern of relapse and remission
over long periods of time, making it even more difficult to assess recovery
rates. Full recovery from (ME)CFS appears to be rare in adults, with an average of only
5% - 10%”.
From “What causes (ME)CFS?” by Professor Anthony Komaroff from
Harvard Medical School
“The biggest change in our understanding
of (ME)CFS over the past 20 years is the abundant evidence that there are
measurable abnormalities in the body in patients with (ME)CFS. I conclude that the controversy as to whether
(ME)CFS is real should be over”.
“Most studies using MRI of the
brain in (ME)CFS have found small scattered areas of
signal abnormality in the brain’s white matter (and) these abnormal findings
most likely are active areas of inflammation and possibly demyelination. SPECT, PET and fMRI
also have generally found abnormalities”.
“Most studies of cognition have
found abnormalities in patients with (ME)CFS. Many studies have found abnormalities of the
autonomic nervous system. A paper
published in 2005 found a characteristic ‘fingerprint’ of specific molecules in
the spinal fluid of patients with (ME)CFS. Spinal fluid, much more than blood, reflects
what’s going on in the brain”.
“The abnormalities of the immune
system are consistent with an assault against some foreign invader”.
“The symptoms of (ME)CFS are experienced in the brain and I suspect most of them
are caused by abnormalities in the brain, but what causes these
abnormalities? Clear possibilities from
the literature include (i) effects of a state of
chronic immune activation on the function of the brain cells (ii) a chronic infection of the brain
by micro-organisms (iii) physical injury to the brain. A chronically activated immune system as
reflected by various blood tests could reflect one of two possibilities or
both: the presence of a micro-organism such
as a virus (or) a defect in the immune system that causes it to become
unnecessarily activated”.
From “Fast Facts: Top Ten Discoveries about the Biology of (ME)CFS”
1. (ME)CFS is not a form of depression and many patients
with (ME)CFS have no diagnosable psychiatric disorder
2. There is a state of chronic, low-grade immune
activation in (ME)CFS
3. There is substantial evidence of poorly functioning NK
cells
4. Abnormalities in the white matter of the brain have
been found
5. Abnormalities in brain metabolism have been discovered
6. (ME)CFS patients have abnormalities in multiple neuroendocrine systems in the brain
7. Cognitive impairment is common in (ME)CFS patients
8. Abnormalities of the autonomic nervous system have
been found, including a failure of the body to maintain blood pressure,
abnormal responses of the heart rate and unusual pooling of the blood in the
veins of the legs. Some studies also
find low levels of blood volume.
9. (ME)CFS patients have disordered expression of genes
that are important in energy metabolism
10. There is evidence of active infection with various herpesviruses and enteroviruses
in (ME)CFS patients. Other infections can also trigger
(ME)CFS, including the bacterium that causes Lyme
disease.
From “It’s all in the
genes” by Dr Jonathan Kerr from St
George’s University of London
“Within the last three
years, researchers have reported various gene signatures in the blood of (ME)CFS patients. We now have data comparing gene signatures of
sudden versus gradual onset and also of resting status versus post-exercise
status. Certain themes of gene activity
are emerging, of which ‘immunity and defence’ is the
most prominent, supporting previous findings on the role of the immune system
in the maintenance of this disease. The
2003 study of Powell et al found that 4 of 12 PCR-confirmed, (ME)CFS associated
transcripts could not be matched to known genes. In the near future, we can expect a
diagnostic test for (ME)CFS, an understanding of the
mechanisms of the disease, and treatments that will work in this tragic and
all-too-common illness”.
From “Immune
System Gone Haywire?” by Susan Levine from
New York City
“Six prominent findings
from the past 18 years of research:
1. impaired function of natural killer cells
2. increased numbers of destructive T cells and increased
percentage of T cells expressing activation markers
3. activation of several pro-inflammatory cytokines
4. dysregulation of the 2-5A RNase L
antiviral pathway
5. predominance of Th-2 cellular immunity
6. differential expression of gene markers whose products cause T
cell activation”.
“In (ME)CFS
there is a shift towards Th-2 predominance (and) there is also frequent
reactivation of latent viruses, another sign of dysfunction of humoral immunity”.
“One of the most exciting
has been (the) report of aberrant cytotoxic activity
among (ME)CFS subjects who demonstrate a differential expression of at least 35
gene sequences compared to matched normal controls. The identity of the protein products of these
genes suggests a link to organophosphate exposure”.
From “On the
Frontier: Some Infections Trigger (ME)CFS in 10% of Cases” by Dr Andrew Lloyd from the
University of New South Wales, Sydney, Australia
“Both the UK and
Australian studies have shown that the development of (ME)CFS
is independent of psychiatric disorder, and that severity of the acute illness
is a key predictor of the subsequent development of (ME)CFS”.
From “Is (ME)CFS
a Brain Disorder?” by Dr Gudrun Lange from New Jersey
Medical School
“Most researchers now acknowledge
that the central nervous system – the brain and spinal cord – somehow plays a
role in (ME)CFS”.
“Neuroimaging
study results: Investigators have used
brain imaging technology to examine whether people with (ME)CFS
have structural and / or functional abnormalities. Both have been found. Three studies found evidence of cerebral
atrophy. This means the brain has
decreased in size, possibly due to the death of brain tissue. Our group found indirect evidence for white
matter loss, and two studies reported a significant reduction in cerebral gray matter.
Numerous dynamic imaging studies have now shown reduced cerebral blood
flow, called hypoperfusion, in (ME)CFS
patients. Reduced cerebral blood flow
has been found globally as well as in the lateral frontal, lateral temporal and
medial temporal lobes. The research
suggests that (ME)CFS patients suffer widespread
cerebral hypoperfusion”.
“A 2005 study found that 30% of
(ME)CFS patients had higher protein levels and / or white blood cell counts in
spinal fluid than normal, suggesting that this subset of patients may suffer
from central nervous system immune dysfunction”.
From “Aspects of the
Illness: Alphabet Soup” by Dr Dedra
Buchwald from the University of Washington
“Every patient with (ME)CFS knows about overlapping conditions. FM. IBS. MCS. TMD (which) makes diagnosis and management
harder for physicians. It also
complicates life for patients, who must deal with scepticism from the
physicians, family members and friends who find it hard to believe that someone
with so many ailments isn’t a hypochondriac, depressed, or eager to assume the
sick role to get attention”.
“In fact, research suggests that
it may be rare for an (ME)CFS patient not to have
concurrent symptoms of other illnesses, and some patients receive formal
diagnoses for multiple conditions”.
“This doesn’t mean that these are
all the same illness masquerading under different names”.
“Irritable bowel syndrome occurs
in 58-92% of (ME)CFS patients”.
With regard to multiple chemical
sensitivity, 53-67% of (ME)CFS patients report a
worsening of their illness with exposure to various chemicals and 55% of FM
patients experience symptoms consistent with MCS”.
“Attributing unexplained clinical
conditions solely to psychological distress or psychiatric explanations is no
longer widely accepted”.
“It seems highly probable that
overlap among unexplained clinical conditions is due, in part, to the complex
interplay between genes and the environment”.
“As a final caveat, describing an
illness an unexplained should not be taken to mean unexplainable or imaginary”.
From “Clinical Care for (ME)CFS” by Marcia Harmon from the CFIDS Association of
America
“The fact that very few
physicians specialise in the care of (ME)CFS patients
and can contribute to the body of knowledge on clinical care has slowed
progress. Coupled with (this) is the growing recognition that there are subsets
of (ME)CFS patients, and what works for one set of
patients may be of little benefit to another group”.
“Because (ME)CFS
is such a complex multi-system illness, clinicians agree that integrative care
is a desirable model. Achieving that
ideal is problematic, because there are so few specialists who know enough
about (ME)CFS to contribute to the team”.
“A physical therapist who doesn’t
understand (ME)CFS is worse than none at all”.
“(Dr David) Bell (paediatric
ME/CFS specialist from New York) says ‘referring patients to someone who
doesn’t understand (ME)CFS is frequently a disaster”.
“(Dr Dan) Peterson also has
difficulty finding knowledgeable specialists, believing this is just one more
reason that the Centres of Excellence concept is so appropriate for (ME)CFS
care. Even after more than twenty years
in the field, he says: ‘I can’t possibly understand everything there is to know
about (ME)CFS.
It’s just far too complex and multisystemic. The pathophysiology
is just too complicated to make it amenable to primary care’. The other clinicians on our panel agree that
Centres of Excellence are needed”.
(Note: this is in direct
contradiction to Wessely’s dictum that pervades the UK, namely: “We see no
reason for the creation of specialist units”; “We do not think that specific
guidelines on the management of CFS should be issued for general practitioners”
and “We believe that the majority of cases can be managed satisfactorily in
primary care”. Ref: Joint Royal
Colleges’ Report CR54, 1996. Whereas
Wessely is deeply reviled by many in the UK ME community, by contrast, Dan
Peterson has a depth of compassion and has dedicated his life to helping (ME)CFS patients and they love him for it).
“Pharmacological approaches have
failed to resolve (ME)CFS. As Stephen Straus, MD, says in a 2004 JAMA
article: ‘No drugs prove to ameliorate the core feature of (ME)CFS: physical and mental fatigue so profound and oppressive
that the term fatigue seems inadequate to describe it’ ”.
“Dr Renee Taylor, professor at
the University of Illinois at Chicago, explains: ‘Losses with (ME)CFS are profound, multifaceted and not limited to social,
economic and functional losses’ ”.
“One of the most controversial
treatments for (ME)CFS is cognitive behavioural
therapy (CBT). Some patients are
fiercely opposed to it because they believe it suggests that if they’d just
change their behaviour or their attitudes about the illness, they would get
better. This opposition has been
strengthened by the British approach to CBT”.
“ ‘I
don’t take the British point of view that CBT is the one thing you can do to
effectively treat (ME)CFS’ says (Professor) Klimas. Lapp agrees.
‘In my opinion CBT is widely but unfairly maligned because of the
British approach, which presumes that (ME)CFS has no
organic basis and is therefore contradictory to current science. This type of CBT assumes somatic symptoms are
perpetuated by errant illness beliefs and maladaptive coping’. Bell (says) ‘It won’t suddenly make patients
better’. Peterson says he’s ‘not
convinced of the efficacy of CBT’ ”.
“The bitter, unpalatable reality
is that (ME)CFS patients can be pro-active, they can
have a good attitude, they can try various drugs and non-drug interventions,
and they can still remain ill, even profoundly disabled”.
From “Fast Facts: A New Definition of Exercise” by Dr Christopher Snell
from University of the Pacific
“It’s somewhat ironic that for an
illness where patients are often diagnosed as deconditioned
and characterised as lazy, exercise exacerbates symptoms rather than relieving
them. Well-meaning health care
professionals often recommend aerobic exercise as a cure-all for the symptoms of
(ME)CFS without fully understanding the potential
consequences of their prescriptions. As
anyone with (ME)CFS who has attempted to ‘get fit’
using traditional approaches to exercise knows, the results can be
devastating”.
From “Patient Perspectives” by Brian Bernard
(the 12 year old son of two physicians)
“(ME)CFS
is not death, but it takes your life away.
It’s very limiting. It engulfs
you in uncertainty because it’s so unpredictable. With (ME)CFS, you
never know what the outcome will be. It
can change your life forever”.
