All rapid responses
Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
Professor Peter White of St Bartholomew's Hospital rightly points out
that "the history of this field has been littered with miscommunications
and misunderstandings".
Professor Stephen Stansfeld of St Bartholomew's Hospital communicated
in 2004 that (1):
"The interface between physical and mental illness (is) typified by
Chronic Fatigue Syndrome. On the interface between physical and mental
illness, research continues into chronic fatigue syndrome and the
development of
treatment trials led by Dr Peter White".
Professor John Garrow, a consultant physician at St Bartholomew's
Hospital, communicated in 2005 that (2) "the most valuable message I
gained from the second session was the observation by Professor Peter
White (Psychological
Medicine, St Bartholomew's Hospital) that patients with chronic fatigue
syndrome (CFS, or ME) have a worse prognosis if the diagnosis they are
given is ME than if it is CFS. He concludes that chronic fatigue implies a
physiological state that the patient may overcome by suitable exercises,
whereas ME implies a viral disease of the brain and muscles over which the
patient has no control."
In their 2007 public communication from the St Bartholomew's Hospital
Chronic Fatigue Syndrome/ ME Service website, there is an article
entitled: 'Expectations for Outcome' (3).
After removing some slightly extraneous material for the sake of
clarity, it basically communicates that:
"We have found that three-quarters of our patients with CFS/ME
significantly improve or recover with treatment in our clinic; research
has suggested that a quarter recover their health and a further half
significantly improve. Some of those who recover don't actually recover,
some don't even improve, and some should go elsewhere".
In 2007 Jason and Brown stated that (4): "Relatively few patients
with CFS completely recover from the illness, with a recovery rate of 0-6%
and increased disability in 10-20% of patients over time", while the CDC
state
(5) : "Improvement rates varied from 8% to 63% in a 2005 review of
published studies, with a median of 40% of patients improving during
follow-up. However, full recovery from CFS may be rare, with an average of
only 5% to 10% sustaining total remission".
Assuming that the Jason, Brown and CDC figures are not unreasonable,
the St Bartholomew's Hospital Chronic Fatigue Syndrome/ ME Service website
communication should perhaps then read:
"We have found that three-quarters of our patients with CFS/ME
significantly improve or recover with treatment in our clinic; research
has suggested that very few recover, some improve and a significant number
get worse. Whilst in
our service, some of those who recover don't actually recover, some don't
even improve, and some should just go elsewhere".
Chia and Chia found that (6) "Enterovirus VP1, RNA and non-cytopathic
viruses were detected in the stomach biopsy specimens of CFS patients with
chronic abdominal complaints. A significant subset of CFS patients may
have
a chronic, disseminated, non-cytolytic form of enteroviral infection,
which could be diagnosed by stomach biopsy".
Dr Jonathan Kerr commented that (7) "the role of enterovirus
infection as a trigger and perpetuating factor in CFS/ME has been
recognized for decades...however, several negative studies combined with
the rise of the
psychiatric 'biopsychosocial model' of CFS/ME have led to a diminished
interest in this area...the importance of gastrointestinal symptoms in
CFS/ME and the known ability of enteroviruses to cause gastrointestinal
infections, led John and Andrew Chia to study the role of enterovirus
infection in the stomach of CFS/ME patients...these intriguing data for
which there is ample supporting data strongly suggest a new and hitherto
unrecognized disease mechanism in CFS/ME patients, which in my opinion,
could trigger and perpetuate this disease...The role of EV infection of
the stomach in the pathogenesis of irritable
bowel syndrome also needs to be clarified in light of these results."
Referring to the 'biopsychosocial model' which has distracted
scientific research and funding into the disease, PACE trialist and
Professor of Cognitive Behavioural Therpay Trudie Chalder insightfully
communicated that (8):
"It is theoretical and it doesn't lead us anywhere".
More precisely, the psychiatrist Dr Niall McLaren wrote (9):
"In practice, if we want to know whether Engel's biopsychosocial
model is truly a model, or just a case of wishful thinking, then a simple
test will decide the
issue. Try making, say, a prediction about a man's psychological state
from his biological data, or vice versa. Or perhaps try to predict wholly
from sociological data which girls will develop post-partum mental
disorders as young women or psychoses in old age. Since nothing like this
can be done, Engel's 'model' is not a model in any interesting sense of
the term" and (10): "In a word, the officially-endorsed biopsychosocial
model is pure humbug, i.e. (some)thing that tricks or deceives; nonsense,
rubbish, just because it does not exist."
Hopefully, the recent advent of the internet (11) should help clear
up any "miscommunications" and "misunderstandings".

None of the many spirited responses to the White et al editorial have
drawn attention to the urgent need to dissect ME from the all-embracing
concept of CFS.
It seems incomprehensible that there has been a multiplicity of guidelines
produced for the management of a disorder for which there is no accepted
aetiology or pathophysiology. Possibly, to a major extent, this simply
reflects the rejection of earlier concepts.
In the second edition of his book, Ramsay noted that the clinical identity
of the ME syndrome was based upon three distinct features.
"1. A unique form of muscle fatigability whereby even after a minor
degree of physical effort. three, four or five days, or longer, may elapse
before full muscle power is restored. (NB. Strenuous activity changes the
shape populations of red cells in both healthy and unwell subjects.)
2. Variability and fluctuations of both symptoms and physical findings
in the course of a day. (A blood sample taken during remission showed
normal features, but six hours later, after a relapse a blood sample was
grossly abnormal.)
3. An alarming tendency to become chronic.
Ramsay discussed the clinical features of ME under three headings.
1. Muscle phenomena. He noted, "...it is important to stress the fact
that cases of mild or even moderate severity may have normal muscle power
in a remission."
(NB It is rare for remissions to be mentioned let alone discussed and no
guideline provides an explanation of their happening. A short paper
titled, "The implications of remissions in ME," was quickly rejected by
the BMJ.)
2. Circulatory impairment. This was manifested as cold extremities and
facial pallor.
3. Cerebral dysfunction. The cardinal features were the impairment of
memory and the power of concentration, plus emotional lability.
It seems strange that Ramsay did not consider that the cerebral and muscle
dysfunction might be related causally to the circulatory impairment, as it
seems that this could be the key factor in the pathophysiology of ME. A
major problem relating to acceptance is that the problems concern altered
blood rheology - and blood rheology is not taught in medical schools.
My work indicates that ME is a dysfunctional state resulting from
inadequate rates of delivery of oxygen and nutrient substrates, due to
impaired capillary blood flow, to maintain normal tissue function. Some
of the background to this claim is summarised below.
In 1986 we reported that ME blood filtered poorly (1) and in the following
year reported similar findings with regard to MS blood. In addition MS
blood viscosity was increased and changed red cell shapes were observed by
scanning electron microscopy.(2) A study which showed that the red cells
of healthy animals and humans could be classified into six different shape
classes (3) was followed by a report that ME blood contained high levels
of cup forms, which would help to understand the poor filterability of ME
blood.(4) The results from a further 99 cases were presented at the
Cambridge Symposium in 1990. In 1992, New Jersey Medicine published an
article relating to idiopathic chronic fatigue in which I pointed out that
individuals who by chance had smaller than usual capillaries would be at
risk of developing chronic sickness after exposure to an agent which
changed the shape populations of red cells.(5)
The implications for ME were discussed in a 1997, invited paper titled,
"Myalgic encephalomyelitis (ME):a haemorheological disorder manifested as
impaired capillary blood flow."(6) In 2001 we reported the results from
red cell shape analysis of more than 2100 blood samples from members of ME
groups in four countries.(7)
It should be noted that SPECT scans show the expected effects of shape-
changed, poorly deformable red cells in reducing cerebral blood flow in
regions which by chance have smaller than usual capillaries.
It has been reported that SPECT scans in three different psychiatric
disorders showed reduced blood flow in different regions of the brain, so
it could be expected for psychological/psychiatric problems to emerge in
some ME people as a part of their dysfunctional state.

NICE says CBT works for ME, and they say that is evidence based.
Apart from that many patients have been saying that it doesn't work, there
have also been many psychiatrists who have done the same. Dr Stein from
Canada has been mentioned, but in a recent article in The World Journal of
Biological Psychiatry, April 2007, Dr Sanders and Dr Korf, from a
psychiatric department in Groningen, The Netherlands, reported the
following: "The psychiatric and psychosocial hypothesis DENIES the
existence of CFS as a disease entity." Now this reminds me very much of
the NICE guidelines; who don't even mention the WHO listing of ME as a
neurological illness. But please read on, because these psychiatrists have
a lot more interesting things to say: "In CFS cognitive behavioural
therapy is most commonly used. This therapy, however, appears to be
INEFFECTIVE in many patients. The suggested causes of CFS and the
divergent reactions to therapy may be explained by the LACK of recognition
of subgroups. IDENTIFICATION of subtypes may lead to MORE EFFECTIVE
therapeutic interventions." I have put these words in capitals, so it is
easier to read, and as this appeared in April, NICE should have known
about it.
I would think that the best way forward, would be a radical revision
of the NICE ME guidelines, and to do what the Canadians did, and what
these psychiatrists have now advised to do as well. Separate ME from other
illnesses with fatigue, so you can offer those others proper treatment,
and you can start looking for a cause and hopefully a cure for ME.

The authors make reference to the PACE trial [1], a major trial in
the area. It seems particularly curious that this trial will use
actigraphy watches before the patients start the trial, but will not use
them again on the patients during or at the end of the trial. This would
give information on whether the patients are increasing their total
activity levels or simply doing the activity that is part of the trial in
the place of other activity they used to do, but which they have cut down
on or cut out altogether.
This is important given previous studies in the area. For example,
one study [2] "using a 26-session graded activity intervention involved
gradual increases in physical activity" found that "from baseline to
treatment termination, the patient’s self-reported increase in walk time
from 0 to 155 min a week contrasted with a surprising 10.6% decrease in
mean weekly step counts."
Another study [3], investigating CBT this time, is regularly quoted
as having showing the effectiveness of CBT for CFS. However if one
examines the actometer data from this study from the group given CBT, the
increases in activity were minimal [4]. For instance, the baseline average
was 67.9, which increased to 68.8 after treatment and to 72.2 at follow-
up. Approximately 4 points. Not unlike the medical care controls, who went
from 64.9 to 68.7 in the same period.
Given the costliness of the trial - over £3m (of UK taxpayers' money)
- it is disappointing that the PACE Trial is not using objective outcome
measures which were previously recommended in a review of CFS
interventions [5]:
"Outcomes such as "improvement," in which participants were asked to rate
themselves as better or worse than they were before the intervention
began, were frequently reported. However, the person may feel better able
to cope with daily activities because they have reduced their expectations
of what they should achieve, rather than because they have made any
recovery as a result of the intervention. A more objective measure of the
effect of any intervention would be whether participants have increased
their working hours, returned to work or school, or increased their
physical activities."
Perhaps it is not too late for this data to be collected from some
participants?

"The uncertainty inherent in making a diagnosis of chronic fatigue
syndrome (CFS) is reflected by the variety of names (such as myalgic
encephalomyelitis; ME)."
Many people who have responded, have mentioned the Canadian and
Australian guidelines; both were unfortunately not used by NICE at all. A
shame really, if you see what an excellent tick list they have produced to
enable doctors to (almost) rule this uncertainty or difficulty out. I say
almost, because there is no medical condition were we, as doctors, get the
diagnosis right all the time.
The other thing I am a bit surprised about, is that the Editorial is
written by a professor in psychiatry and the second article in the same
BMJ about ME and NICE was written by another professor. When I Google a
bit, this is what I find on his site about him:
"The Department of Health Sciences at the University of Leicester is a
research-led department with established strengths in epidemiology,
medical statistics, social science, public health, primary care, health
services research and PSYCHIATRY."
All really NICE, but why wasn't someone like Dr Speight the
Paediatrician, who has specialised in ME for more than twenty years, or Dr
Chaudhuri, the neurologist, who also specialises in ME (and a few other
neurological diseases) and who both acknowledge the fact that ME is a
neurological disease, as Classified by the WHO, not asked instead to write
about ME??? It would have given a much more balanced view if both a
Neurologist and a psychiatrist would have written about this subject which
is deemed by many as a controversial disease, just as we did with MS for
example, when it was still called Hysteria. Even though I, and many
others, think after reading the splendid psychiatric guidelines about ME
by Dr Stein, that the psychiatrist ONLY has a role in this chronic
neurological disease if patients develop a depression or so alongside
their ME.
Competing interests:
We as psychiatrists should spend more time helping patients with a mental health problem instead of wasting valuable time and resourches on a neurological illness.

Many things have already been said, but I would like to take this
opportunity to add a few things:
The recently finished Gibson Enquiry states that: “In Britain, there has
been a clear historical bias towards research into the psychosocial
explanations of CFS/ME. This is despite Parliament recognising ME as a
physical illness in a Private Members Bill, the ME Sufferers Bill, in
1988.”
Furthermore it mentions that “The WHO (World Health Organisation) in
Geneva holds an internationally recognised classification that ME is a
neurological disease."
And in February 2004, the then Health Minister (Lord Warner) made it very
clear, in a formal written acceptance, "that the UK ACCEPTS the World
Health Organisation classification of ME as a neurological disorder.”
And now if you keep that in mind and just read the NICE guidelines on
ME again DEAR MR EDITOR. More than a hundred pages and NOWHERE do they
mention that ME is a NEUROLOGICAL illness. NOWHERE AT ALL.
Now I also have a question for all the people who have written
excellent responses on this page. I have started a BLOG:
http://niceguidelines.blogspot.com/
Is it alright if I would use some of your comments on my BLOG?? If
not or if you have any suggestions, please let me know. My email address
is on the right hand side of my Blog.
All the patients and carers for patients with ME, all the best. Can I take
this opportunity to thank all the doctors who are working hard and trying
to help us.
And for Mr NICE, maybe go and visit a few patients with Severe ME, I'm
sure you will get a totally different view and you will understand why the
Canadian and Australian guidelines are so much better and also so much
more helpful to get the diagnosis right. Because remember, people with ME
we can't cure, but the many people who haven't got ME, see also professor
Mirza's response on
http://www.bmj.com/cgi/eletters/335/7617/446#top,
who wrote that 90% of the patients he sees with a diagnosis of ME have
something else with fatigue, we can ACTUALLY TREAT. And that sounds a lot
better I can assure you.

Who is relieved by NICE? Probably the government and the other socio-political forces which do not see the usefulness of treating, or trying to
treat, these conditions.
In my opinion, the reasoning behind the guideline published by Nice
is contradictory.
First, NICE states that the causes which trigger these types of
syndromes are unknown.
Although this is true of many conditions, it does not stop doctors
from offering cures and treatments. The existence of a disease is not
subjected to doctors' will, neither is its cure, neither doctor’s
acceptance nor awareness of its existence. By now, after thousands of
years of the existence of doctors’ medicine, doctors should be aware that,
in medicine, today’s revealed truth is tomorrow’s heresy.
It seems that Nice guidelines were formulated under the this axiom
:
"E.M. does not exist, it is an imaginary illness, which exists only
in the minds of the E.M. / sufferers, and therefore any clinical
investigation is totally unnecessary. It is self-explanatory"
Then the guidelines suggest to proceed as follow:
1- To exclude all symptoms and all clinical findings, chemical
abnormalities etc., which can also be seen in other syndromes/conditions,
to exclude all infections, co-morbidity, etc. which can be present.
2- Also the clinicians will have to limit the clinical investigations
to a simple, basic, blood test and nothing else.
3- Then, after having excluded any symptom, any biological
abnormality, known to mankind, the clinicians should proceed with the
formulation of "mental illness" by using
mental descriptors listed in the appendix.
Comments about Nice guideline:
1 -Many symptoms and abnormal clinical findings are commonly present
a huge amount of diseases. To exclude a symptoms or a disease from the
differential diagnosis can be dangerous. To exclude "all" symptoms and
diseases from a hypothetical diagnosis, simply because they can be also
present in other conditions, also means to exclude the existence of
symptoms and conditions. Ultimately, this could mean that there are no
biological diseases.
Then, having denied the existence of certain biological diseases, simply
because they might have symptoms and biochemical abnormalities which, can
be found in other diseases, the doctors will have to formulate the
diagnosis of mental illness by applying mental "descriptors", which are
universal feelings, and they are present in all humans, all the time.
Therefore, when examining the biological aspect: Nice suggests to
eliminate all physical causes, chemical abnormalities, symptoms etc,
which can be also present in order physical conditions. This process
will excludes the physical condition of ME.
Then Nice suggests to apply at least two mental descriptors, which
are common and present every person, to establish that ME is indeed an
esclusively mental illness.
Therefore, two different and opposite type of considerations are used for
the diagnosis of ME.
A)Total exclusion of physical conditions/symptoms etc, of all biological
“descriptors” which can be found in other biological diseases.
B)Inclusion of universally common “mental” descriptors (but I would say
universally common human feelings) to ascertain with absolute certainty
the existence of ME as a mental disease. A disease which is only mental.
Point A contradicts B and vice-versa. This type of method is typical of
“Spanish Inquisitions”, which have pestered Europe during the Middle Ages.
NICEs approach has nothing to do with the scientific method.
Guidelines like this are neither scientific, nor doctrinal. At best
they are an example of the most hideous type of quackery.
In spite the fact that NICE et Al deny their biological existence,
M.E. diseases have been spreading all over the world in an epidemiological
pattern which seems to be more indicative of an infective nature, rather
than a mental one. Furthermore, it seems that this diseases are spreading
at increasing rates.
The very concept of mental disease varies from time to time in a
given society, and also from society to society.
Traditionally, in certain oriental societies the concepts of mental
disease, as it is construed in the West, did not exist. For instance, in
traditional Chinese Medicine “depression” is a dysfunction of the meridian
of the liver.
I would suggest to the NICE people to concentrate first on the
physical before focusing on the metaphysical.
For the metaphysical we already have priests.

The proponents of various reinterpretations of Chronic Fatigue
Syndrome appear concertedly neglectful that CFS has a verifiable history
which can be traced back to a very specific time and place - and a
particular pivotal phone call made by Dr Peterson which set the entire
process in motion.
It could have been different. The CDC might have responded to any of
a number of different doctors who were reporting the mysterious illness
across the USA, but as it happened, Lake Tahoe seemed like a more
desirable place to conduct an investigation.
By such quirks is history determined.
The initial identification of the epidemic to the direct creation of
the partial symptom collation which was called CFS can be traced in an
unbroken chain of events performed by specific people who are still
accessible.
There is no need for any confusion about what CFS orignally was meant
to describe, because the story is accurately depicted in Osler's Web,
reiterated by Dr Petersons contribution to the Canadian Consensus
Guidelines, and the individuals involved are mostly still alive, and able
to answer anyone who cares to ask about their experience.
When a group of people is selected to become prototypes for a
syndrome, does it not seem spectacularly imprudent to conspicuously ignore
them and turn the illness into something else?

Chlamydia pneumoniae infection a treatable cause of Chronic Fatigue Syndrome
The Editor
British Medical Journal
CHRONIC FATIGUE SYNDROME OR MYALGIC ENCEPHALOMYELITIS
In your Editorial (BMJ 2007; 335: 411-2), relating to the NICE
clinical guidelines which appeared later in the Journal, you state “We
remain unsure of the causes”. In the guidelines also there is no mention
of the possibility of an infective cause, or of the possible role of
antibiotics in the treatment. NICE remarks that the attending physician
does not need to look for evidence of bacterial or viral infection unless
there has been clinical evidence of such an infection. However, such
evidence can be so mild as to escape mention by the patient. There is
evidence in the literature (1,2,3,4) and considerable anecdotal evidence
(See website www.Cpnhelp.org) that Chlamydia pneumoniae (Cpn) infection
may be the cause in some cases of Chronic Fatigue Syndrome and of the
linked syndrome Polymyalgia Rheumatica (Fibromyalgia), and also that a
trial course of antibiotics is worthwhile(3,4).
Cpn infection is common and frequently involves more than one member
of the family. It exists in two forms. In the initial stage it is
transmitted in an extra cellular form by coughing and may give rise to flu
-like attacks, separated by weeks of continual coughing, often resulting
in chronic laryngitis. In the later stage it changes to being an
intracellular infection, which may be asymptomatic, persisting for life,
or may give rise to symptoms. In the intracellular form the organisms,
coccal in shape, multiply within vacuoles; their cell walls are deficient.
They act on mitochondria, depriving them of ATP; this curtails production
of energy, resulting in symptoms dependent on the cells affected - in
brain and muscle cells, this could result in Chronic Fatigue Syndrome and
in the CNS result in Multiple Sclerosis(5). If present in an inflamed area
such as in muscles, it can
increase the degree of inflammation by up to 5 times, thus causing painful
myalgia.
Because its cell wall is deficient, the antigenic response is low
giving rise to only minimal levels of antibodies. In consequence;
serological tests for diagnosis are unreliable at this stage. This would
explain the negative serology in some reports(6).
Treatment with antibiotics is difficult because drugs have to
penetrate the host cell wall as well as the intracellular organisms.
Treatment needs to be prolonged and pulsed, because of continual
replication of the intracellular forms. Until adequate diagnostic
facilities are readily available treatment needs to be in two stages: the
first stage, which is diagnostic, involves the use of two long-term
bacteriostatic antibiotics for 6 weeks, and the second, meant to be
curative, involves the introduction of a third bactericidal antibiotic.
One possible choice of antibiotics for the first stage is a
combination of Doxycycline and Azithromycin. Initially, the Doxycyline
needs to be given alone in low dosage for two weeks, because of the risk
of a Herxheimer reaction resulting from the release of toxins by damaged
bacteria. Such reactions are usually mild and short-lived. If stable after
two weeks, Azithromycin in low dosage is added for 4 weeks.
Roxithromycin can be used in place of Azithromycin. . Improvement of
symptoms, or the occurrence of a Herxheimer reaction, confirms the
diagnosis.
If the diagnosis is confirmed, the second stage involves long-term
pulsed treatment with the above antibiotics, plus the cautious addition of
a third bactericidal antibiotic (e.g. Metronidazole or Tinidazole), with
an appropriate break in giving the third antibiotic if the patient should
have a severe Herxheimer reaction. Mild Herxheimer reactions usually
settle spontaneously and need not interrupt treatment.
The above suggested treatment is based on the David Wheldon Protocol
for Multiple Sclerosis, available on the Internet (Wheldon
protocol/Cpnorg.org/Chlamydia pneumoniae).
