Researchers have identified biological markers in both gut bacteria and blood that can be used to diagnose chronic fatigue syndrome - also known as myalgic encephalomyelitis, or ME/CFS - in more than 80 percent of patients tested. ME/CFS is currently difficult to diagnose – it was only last year that it was properly classified as a real disease, and the existing treatment options are limited and controversial... the researchers found that ME/CFS patients had less diversity in their gut bacteria than the control group - specifically, fewer bacterial species that were anti-inflammatory and more which were pro-inflammatory....
The CDC reports that one million Americans have CFS. This illness strikes more people in the United States than multiple sclerosis, lupus, and many forms of cancer....CFS occurs four times more frequently in women than in men;... The illness occurs most often in people in their 40s and 50s...CFS occurs in all ethnic and racial groups and in countries around the world....People of all income levels can develop CFS. With his son terribly ill, a top scientist takes on chronic fatigue syndrome
In 2011, a study published in The Lancet claimed that it had done exactly that: The data, the authors declared, showed that a combination of exercise and talk therapy could significantly alleviate the symptoms of the disease, and even cure it fully in up to 20 percent of cases. Immediately, the study (also called the PACE trial) was both hailed as a great leap forward and criticized as bad science.
And now, definitive proof has emerged that the latter camp was correct. In a column published in Stat today, writer Julie Rehmeyer — herself a CFS patient — explained how a supposed breakthrough blew up so spectacularly. Soon after the study was published, Rehmeyer wrote, she and other CFS patients, skeptical of the study’s claims, began to examine it more closely. What they found looked a lot like manipulated data:
But patients like me were immediately skeptical, because the results contradicted the fundamental experience of our illness: The hallmark of ME/CFS is that even mild exertion can increase all the other symptoms of the disease, including not just profound fatigue but also cognitive deficits, difficulties with blood pressure regulation, unrestorative sleep, and neurological and immune dysfunction, among others.
Soon after I was diagnosed in 2006, I figured out that I had to rest the moment I thought, “I’m a little tired.” Otherwise, I would likely be semi-paralyzed and barely able to walk the next day.
Research published the Proceedings of the National Academy of Sciences suggest Chronic fatigue syndrome may be a human version of 'hibernation'
After looking at the 612 different metabolites...They found that 80 percent of the metabolites were lower in those with CFS. They also found what they described as “abnormalities” in 20 of the metabolic pathways. All this suggests that the metabolism of people with CFS is markedly slowed down.....although humans do not, in fact, hibernate, he said the “metabolic signature” is similar to that of animals in hibernation.... If that were the case, he explained, curing people of CFS may be akin to waking the body up. Davis said it’s possible that the treatment may not be anything radical; it might involve putting the body back in balance with the right mix of diet and supplements.Posted by Jill Fallon at September 22, 2016 8:08 PM | Permalink
But even Davis cautioned that however alluring the paper’s implications are, “it is only a hypothesis.” The scientists are now trying to replicate the PNAS study with a larger sample size.
