Study to reveal causes of chronic fatigue syndrome

Scientists at the University of Liverpool are the first to use a new laboratory technique that could reveal the causes of Chronic Fatigue Syndrome (CFS).

CFS is a severely debilitating illness, characterised by prolonged fatigue that can be triggered by minimal activity. Fatigue is accompanied by symptoms that may include painful muscles and joints, disordered , gastric problems and .

The causes of the condition are unknown, but some studies have suggested that a defect in the energy producing components of , called mitochondria, could be responsible. Other studies, however, have not been able to demonstrate this defect. It is thought that limitations in the methods used to determine mitochondrial function in fibres could be the reason why the causes of CFS have been difficult to explore.

Scientists at Liverpool are the first to implement a newly developed technique that is more sensitive to identifying mitochondrial function within the muscle’s fibres. Researchers anticipate that these new methods will demonstrate whether skeletal muscle mitochondria in patients with CFS are dysfunctional, which would result in muscle fatigue and further complications leading to chronic inflammation and pain.

Professor Anne McArdle, from the University’s Institute of Ageing and Chronic Disease, said: “The mechanisms that lead to debilitating muscle fatigue and pain in CFS patients are unknown. The time required for diagnosis further complicates the identification of the factors responsible for triggering the illness. Reversal of the severe fatigue that follows remains the most promising form of treatment.

“Scientists have hypothesised that mitochondria malfunction, significantly reducing the energy supply to the muscle cells that allow the body to carry out its daily activities. The pain and inflammation that follows can cause further mitochondrial abnormalities and so the vicious cycle of events continue.

“At Liverpool we have established newly developed techniques in the laboratory that can identify dysfunction as it occurs in the muscle cells. It is at this point we can look at interventions to reverse or halt further damage.”

Unfortunately a promising treatment was nixed by the FDA because of "abuse" fears. There have been studies revealing that chronic fatigue/fibromyalgia patients have a high incidence of what is called alpha-wave intrusion in which they have alpha waves running through their Delta sleep on EEG during sleep.
Using a med called Sodium Oxybate patients saw significant reductions in fatigue within 1 week through a 14 week study of 548 fibro patients in a double-blind placebo study.
FDA refused to allow them to go to stage III trials. This, in spite of the fact that several million people in the US are now estimated to have one or the other.
This is personal for me. My mother had Chronic fatigue for years before she passed away. My wife was diagnosed in 1990 and is disabled because of it and I have been disabled as a result of Fibromyalgia since 1999.
I would love to wake up one stinking day...just one, and feel like I actually had slept. I want to work again and be useful. FDA SUCKS!
