ME/CFS Common Data Element (CDE) Project

Member of the Biomarkers Working Group of the Myalgic Encephalomyelitis/Chronic Fatigue Syndrome Common Data Element (CDE) Project sponsored by the National Institute of Neurological Disorders and Stroke and the Centers for Disease Control and Prevention. This working group reviewed data collection instruments widely used by investigators in the ME/CFS field, and either recommended their use unchanged or (more often) proposed some modifications.

Notable studies

• 2015, Brain-derived neurotrophic factor concentration may not be depressed in chronic fatigue syndrome (Abstract)
• 2019, Whole blood human transcriptome and virome analysis of ME/CFS patients experiencing post-exertional malaise following cardiopulmonary exercise testing (Full text)

Talks and interviews

myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.

The human virome is the collection of all viruses that are found in or on humans.

post-exertional malaise (PEM) - A notable exacerbation of symptoms brought on by small physical or cognitive exertions. PEM may be referred to as a "crash" or "collapse" and can last for days or weeks. Symptoms can include cognitive impairments, muscle pain, trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, and others.

UK CFS/ME Research Collaborative (CMRC) - A UK group of researchers and ME/CFS patient groups led by Professor Stephen Holgate. Its launch in 2013 was covered by the Science Media Centre. Since 2014, the collaborative sponsors the CFS/ME Research Collaborative Conference.

chronic disease a disease or condition that usually lasts for 3 months or longer and may get worse over time. Chronic diseases are long-term (typically incurable and requiring long-term management) but are not necessarily severe.
