Association of biomarkers with health-related quality of life and history of stressors in myalgic encephalomyelitis/chronic fatigue syndrome patients.

Fenouillet, Emmanuel, Vigouroux, Aude, Steinberg, Jean Guillaume et al.·Journal of translational medicine·2016

This study examined blood markers and muscle function in 36 ME/CFS patients compared to 11 healthy controls to understand whether biological changes relate to symptoms and quality of life. Researchers found three key differences: problems with muscle response to exercise, increased oxidative stress (cellular damage), and changes in immune cells. These biomarkers correlated with how much ME/CFS affected patients' daily lives, especially in those whose illness started after a severe infection.

Chronic fatigue syndrome versus sudden onset myalgic encephalomyelitis.

Jason, Leonard A, Evans, Meredyth, Brown, Abigail et al.·Journal of prevention & intervention in the community·2015

This study looked at whether using a specific definition of ME (sudden onset myalgic encephalomyelitis) identifies a sicker group of patients compared to the broader CFS (chronic fatigue syndrome) definition. Researchers found that people who met the ME criteria had more severe symptoms, greater disability, and worse post-exertional malaise (feeling much worse after physical activity) than those meeting only the CFS criteria. The findings suggest that the ME definition may identify patients with more serious illness.
