King's College, London published the following article in May 2015 which reports they were funded by Arthritis Research UK to research and develop a reliable blood test to identify fibromyalgia and potentially develop new treatments.
Fibromyalgia is common pain syndrome causing widespread muscle and bone
pain, as well as fatigue and disturbed sleep. It has no obvious physical
cause, is poorly understood and difficult to diagnose, treat and
manage. For years there was doubt among the medical profession whether
fibromyalgia actually existed – except in the minds of patients.
(Sadly, this is still true of some medical professionals!!)
There is still no specific blood test, scan or x-ray that can
confirm a diagnosis of the common pain syndrome, although blood tests
are often carried out to rule out other conditions.
Now scientists at King’s College London, funded by a three year
grant of £171,000 from Arthritis Research UK, are hoping their latest
research will lead to a reliable blood test to enable doctors to make a
proper diagnosis.
The research team will examine samples and measurements taken from
400 twin volunteers from the 13,000 Twins UK Bioresource in which one
twin has chronic widespread pain, to try to identify biomarkers in the
DNA associated with the condition. It will be compared with the DNA of
their healthy twin, to establish differences.
“Currently there is no blood test for fibromyalgia which makes
diagnosis difficult,” explained lead researcher Dr Frances Williams from
the Department of Twin Research & Genetic Epidemiology. “And
treatment is limited, and in many cases unsatisfactory.
“Our research will help patients in two ways. First it will
contribute to our understanding of how fibromyalgia – and other chronic
pain syndromes such as irritable bowel syndrome – develop – and point to
pain pathways, which we may not have suspected.
“Secondly, we hope it will lead to identification of a biomarker
which we could work into a blood test. As well as enabling the condition
to be diagnosed more effectively, it could help to ‘stratify’ patients
into groups depending on disease severity, which will help in clinical
trials of potential new treatments. It might even help us predict how
the condition will progress.”
Fibromyalgia is known to have genetic influences but there are
many complicated steps between the genes which are responsible for
fibromyalgia and the condition itself. The King’s team hopes to explore
these steps in more detail and shed light on the underlying biology of
the condition.
Specifically, this study will focus on identifying markers on the
outside of DNA that are associated with the switching on or off certain
genes. DNA ‘switching’ is very important to health, as it prevents
inappropriate processes from occurring in the body when they should not.
The project aims to assess the profile of DNA markers in healthy
and affected twins. If there is a difference between these marker
profiles on certain DNA regions associated with chronic pain onset
between twins, then this DNA marker could be used as an indicator for
disease.
Dr Natalie Carter, head of research liaison at Arthritis Research
UK commented: “Fibromyalgia is notoriously difficult to diagnose and
treat, partly because we know so little about why it occurs and how it
progresses. Being able to diagnose it would be a major step forward, and
understanding more about the influence of genetics will allow us to
develop treatments specifically for people with fibromyalgia in the
future.”
I'm keeping my fingers firmly crossed that they are successful - and soon!!
