We may finally learn more about chronic fatigue syndrome (also called myalgic encephalomyelitis or ME / CFS in medical jargon), a disease that affects between 1 and 2% of the world’s population, and whose causes are still well established. mysterious.
This disease is characterized by persistent fatigue, joint pain, muscle weakness, headaches and memory impairment. But so far, researchers have not yet discovered the origins of this syndrome. which also affects adolescents.
Towards the development of a blood test
A Stanford University study(United States) will undoubtedly shed new light on the disease. American researchers have in fact linked chronic fatigue to variations in 17 signaling proteins of the immune system (cytokines) whose concentrations in the blood correlate with the severity of the disease.
Scientists found that certain cytokine levels were lower in patients with a mild form of the disease and particularly high in patients with relatively severe symptoms.
“There is a lot of controversy and confusion around chronic fatigue syndrome, even if it is a real disease “said Dr. Mark Davis, who conducted the research. “Our results clearly show that it is an inflammatory disease and provide a solid basis for the development of a diagnostic blood test.”.
