REPORT OF ME/CFS FORUM
Forum Imperatives
- To examine the strength of the biological evidence
- To develop consensus for ME/CFS research criteria
- To initiate protocols for post-mortem examination
- To initiate the establishment of a tissue/brain
bank
Introduction
The Adelaide ME/CFS Forum was an informal meeting
of researchers and clinicians invited to present their work and to
reach consensus on the issues around clinical diagnostic and research
criteria for ME/CFS. When tight subject cohorts are identified, then
ME/CFS research outcomes will more reliably progress medical knowledge
to assist those who suffer with ME/CFS.
Background
US Centers for Disease Control CDC research finds:
- CFS patients are more sick and have far greater
consequent disability than patients with chronic obstructive lung
disease, cardiac disease, osteoarthritis, and depression;
- $9.1 billion earnings are lost annually in
the US due to disability caused by CFS;
- Fewer than 16% of sufferers in the general
population are diagnosed and treated for CFS;
- The strongest predictor of the development
of post infectious (chronic) fatigue syndrome is the severity of
the acute illness at onset. Psychological factors play no role in
the development of CFS following infection.

Association for Chronic Fatigue Syndrome AACFS Conference October
2004)
ME/CFS has been formally classified by the World
Health Organisation WHO as a neurological disorder in the International
Classification of Diseases ICD since 1969 (ICD10, G.93.33).
ME/CFS is a broad diagnosis
which includes a spectrum of clinical syndromes linked to known
infections agents including Ross River virus, Epstein Barr virus, Q
fever, Lyme disease, parvovirus B19 and toxic exposures such as organophosphates.
These syndromes are characterized by neurological, gastrointestinal,
cardiovascular and myoarthralgic features. Severe forms can present
with paresis, seizures, intractable savage headache, and lifethreatening
complications. The renaming to chronic fatigue syndrome in 1988,
giving misplaced emphasis to "fatigue" trivialises the
substantial disability of ME/CFS which can extend to the wheelchair
or bed bound, requiring 24 hour care.
Without a diagnostic test to confirm their clinical state, people
with ME/CFS are frequently dismissed with a smorgasboard of psychiatric
labels, their acute health care needs ignored. Strong evidence including
genetic predisposition, persistent infection and immune dysregulation,
in the pathogenesis of these complex syndromes is accumulating.
Barriers to clinical care and strategic research development
funding
"Sufferers have all been classified
under one diffuse CFS heading. To conduct scientifically rigorous
research with replicable findings, including clinical trials, it
is essential to know exactly what symptoms are to be examined and
as a result identify tight subject cohorts. Using the current fairly
amorphous definitions of CFS for research studies will not provide
outcomes that would reliably progress medical knowledge to assist
CFS sufferers." – Professor Judith Whitworth, Chief
Medical Officer, Department of Health and Aged Care 1999
