Coping with chronic fatigue.
Dr. William Weir, Consultant
at Coppett’s Wood Hospital, part of the Royal Free, specialising in
infectious and tropical diseases.
Dr. Weir began saying that
some people have the impression that CFS/ME is a new condition that
started in the 1980’s when the Sun and the Mirror were writing about
‘yuppie flu’ and a ‘malingerer’s charter’. Not so. He gave a detailed
account of how in the 17th century a condition very like CFS/ME was
described and how Charles Darwin and Florence Nightingale may well have
had the symptoms.
However, in the psychiatric
community it is still felt that CFS/ME is subconsciously produced and
is in some way the patient’s fault.
Dr. Weir does not believe that
it is valid to group illnesses into psychological and organic
conditions. All disease has an organic basis. Patients suffering with
depression have neuro-chemical abnormalities in their brains that can
be treated with chemicals, ie antidepressant drugs. Patients with
schizophrenia have been found at post mortem to have a disorder in the
temporal lobes of the brain. These illnesses are just as organic as
pneumonia.
Most disease is the product of
environmental factors and individual susceptibility. Old people are
more vulnerable to infections than younger people. Children get more
viruses than adults but deal with them more effectively. Genetic
make-up can also affect our susceptibility to disease. For example,
Europeans in Africa are as likely to develop malaria as the local
population but get it more severely.
The presence of pathogens
is an important environmental factor. Dr Weir gave examples of several
medical misunderstandings in this area. Until recently it wasn’t
realised that a bacterium called helicobacter causes peptic ulcers. A
further striking example comes from the past: general paralysis of the
insane, a condition where patients develop dementia, have grandiose
delusions and believe they are Napoleon or Hitler. This was once
thought to be the result of too much hard work and intellectual effort,
but is, in fact, the end stage of the venereal infection Syphilis. Dr.
Weir raised laughter in the audience when he said it was not their
brains that these patients had over-exercised.
Stress: deer who
were stressed by being chased by a motorbike developed TB but the other
deer who were not chased didn’t, though they had been equally exposed
to the pathogen. Research on humans has shown that patients who are
stressed prior to developing the common cold excrete the virus for
longer than patients who are not stressed. There is clearly cross talk
between various centres of the brain controlling psychological
functions and the immune system.
People with ME show
abnormalities in the immune system, in the vascular system and in the
mitochondria, the powerhouse in cells. Abnormalities in the vascular
system are both micro-vascular (eg. reduction of capillary blood flow
to the brain stem) and macro-vascular (eg. problems with blood pressure
control which can lead to dizziness when standing, which is known as
postural hypertension). Annoyingly, these irregularities are not
consistent in all patients and are variable in individual patients, so
that a patient can sometimes feel dizzy and other times not. This
variability provides scope for sceptics.
Dr. Weir’s clinical approach is to exclude other causes. He has had patients present with AIDS and brain tumours. He uses the Fukuda criteria
which require patients to have throat, sore neck glands, joint pain,
post exertion fatigue lasting more than 24 hours and cognitive
difficulties. Many patients are very sensitive to alcohol and
anti-depressants.
In relation to treatment he
says that there is no magic bullet; his approach is to maximise the
body’s own ability to recover through pacing activity. His clinical
impression is that red meat and refined sugar are bad for people with
ME. It may be worth trying cutting out grain and dairy products for 4
to 6 weeks. It is
important to eat a good diet with fruit, vegetables, chicken and fish.
Supplements of Omega 3 and 6 fatty acids are beginning to achieve
respectability. Small doses of amitryptiline can help with disturbed
sleep and have less addictive potential than the benzodiazepines. The
non-steroidal anti-inflammatory drug Celebrex which is a prostaglandin
inhibitor can help, possibly by affecting micro-vascular disturbances
in the brain stem by opening up the small capillaries. However,
long-term use may increase the likelihood of cardio-vascular disease
and therefore it should only be taken for 3 or 4 weeks during bad
periods.
Recovery is
frequent within the first year of the illness and there is a better
prognosis if there are periods of remission. He has seen patients
recover after 10 years but this is rarer. He does not believe there is
a specific pathogen. CFS has followed from EB virus infection,
salmonella, tetanus injections or whiplash injuries, probably
triggering a common pathway in a susceptible individual. CBT can be
helpful to some patients early in the illness if they are very negative
and depressed about the illness, but he believes medication techniques
are more effective. The mind and body are closely allied. Probably what
is most helpful about psychotherapy is not specific techniques, but
therapeutic engagement with the therapist.
Dr. Weir concluded by saying
that CFS/ME is a real illness and a serious problem. People with ME
can’t carry on with activity because of a physical disorder in the
brain cells. Anyone who denies this is inhumane; the medical
establishment is coming to recognise the illness. Finally he told the
audience that there was light at the end of the tunnel. A cause is
going to be found fairly soon and those who deny the organic basis of
the condition will “have egg on their faces!”
