Chronic fatigue syndrome (CFS) is a mysterious and maddening condition, with no cure or known cause. But researchers, using a variety of techniques to identify and assess targeted metabolites in blood plasma, have identified a characteristic chemical signature for the debilitating ailment and an unexpected underlying biology: It is similar to the state of dauer, and other hypometabolic syndromes like caloric restriction, diapause and hibernation. Dauer is the German word for persistence or long-lived. It is a type of stasis in the development in some invertebrates that is prompted by harsh environmental conditions. The findings are published online in the...

If your doctor diagnoses you with chronic fatigue syndrome, you’ll probably get two pieces of advice: Go to a psychotherapist and get some exercise. Your doctor might tell you that either of those treatments will give you a 60 percent chance of getting better and a 20 percent chance of recovering outright. After all, that’s what researchers concluded in a 2011 study published in the prestigious medical journal the Lancet, along with later analyses. Problem is, the study was bad science. And we’re now finding out exactly how bad. Under court order, the study’s authors for the first time released...

“Our work demonstrates that the gut bacterial microbiome in chronic fatigue syndrome patients isn’t normal, perhaps leading to gastrointestinal and inflammatory symptoms in victims of the disease,” said Maureen Hanson, a professor of molecular biology and genetics at Cornell. “Furthermore, our detection of a biological abnormality provides further evidence against the ridiculous concept that the disease is psychological in origin.” In a study published this month in the journal Microbiome, Cornell University researchers looked at stool and blood samples of 48 people diagnosed with chronic fatigue syndrome (or more formally, myalgic encephalomyelitis) and at 39 healthy volunteers. They found two...

In response to requests by U.S. patient organizations and advocates, the U.S. Agency for Healthcare Research and Quality (AHRQ) has issued an Addendum to its 2014 ME/CFS evidence review. This Addendum downgrades the conclusions on the effectiveness of cognitive behavioral therapy (CBT) and graded exercise therapy (GET), and this has tremendous implications for medical education and treatment recommendations. GET is Ineffective for ME Patients. CBT Is Barely Effective.

Before he got sick, Whitney Dafoe was an award-winning photographer and a world traveler. But now, at 31, Whitney lies in bed in a darkened room in his parents’ home, unable to talk, walk or eat. This isn’t the picture that people imagine when they hear “chronic fatigue syndrome,” which is often viewed by the public and the health-care community as a trivial or primarily psychological complaint.In a February report, the Institute of Medicine gave the illness a new name — systemic exertion intolerance disease. Many patients have long criticized the name “chronic fatigue syndrome” for not reflecting the seriousness...

Chronic fatigue syndrome is a "serious, debilitating" condition with a cluster of clear physical symptoms — not a psychological illness — a panel of experts reported Tuesday as it called for more research into a disease that may affect as many as 2.5 million Americans. "We just needed to put to rest, once and for all, the idea that this is just psychosomatic or that people were making this up, or that they were just lazy," said Ellen Wright Clayton, a professor of pediatrics and law at Vanderbilt University, who chaired the committee of the Institute of Medicine, the health...

Distinct changes in the immune systems of patients with ME or chronic fatigue syndrome have been found, say scientists. Increased levels of immune molecules called cytokines were found in people during the early stages of the disease, a Columbia University study reported. The US research team, who published their findings in the journal Science Advances, tested blood samples from nearly 300 ME patients and around 350 healthy people. They found specific patterns of immune molecules in patients who had the disease for up to three years. These patients had higher levels of of cytokines, particularly one called interferon gamma, which...

Patients with chronic fatigue syndrome are accustomed to disappointment. The cause of the disorder remains unknown; it can be difficult to diagnose, and treatment options are few. Many patients are still told to seek psychiatric help. But two recent studies — one from investigators at Stanford a few weeks ago and another from a Japanese research team published earlier this year — have found that the brains of people with chronic fatigue syndrome differ from those of healthy people, strengthening the argument that serious physiological dysfunctions are at the root of the condition. Both studies were small, however, and their...

Chronic fatigue syndrome (CFS) is an often-debilitating condition of unknown origin. There is a general consensus among CFS researchers that the symptoms seem to reflect an ongoing immune response, perhaps due to viral infection. Thus, most CFS research has focused upon trying to uncover that putative immune system dysfunction or specific pathogenic agent. However, no single causative agent has been found. In this speculative article, I describe a new hypothesis for the etiology of CFS: infection of the vagus nerve. When immune cells of otherwise healthy individuals detect any peripheral infection, they release proinflammatory cytokines. Chemoreceptors of the sensory vagus...

A study published on Oct. 19, 2011, in PLoS ONE reports on results of a double-blind, placebo-controlled trial of the drug rituximab in CFS. The results of this study showing that two infusions of rituximab may provide durable relief from CFS are extremely encouraging. The most exciting news from the study is the possibility of disease-modifying treatment for at least some people with CFS. This study also provides support for other possible approaches to repair immune abnormalities that have been identified in CFS patients. The authors state that the results support the concept of CFS as an autoimmune disease. They...

In a blow to patients with chronic fatigue syndrome, two new studies published on Tuesday raised serious doubts about earlier reports that the disabling disease is linked to infection with XMRV, a poorly understood retrovirus. The new papers were posted online in the journal Science, which in October 2009 published the initial research linking XMRV to chronic fatigue syndrome. In an “editorial expression of concern” accompanying the two new studies, Bruce Alberts, editor in chief of the journal, declared that the earlier finding “is now seriously in question” and was most likely due to laboratory contamination. Dr. Vincent Racaniello, a...
