Study found syndrome of Chronic fatigue which may help lead to a diagnostic by blood test. US researchers have identified bio-markers associated with the severity of chronic fatigue syndrome (CFS). The department of Chronic Fatigue syndrome says many patients have flu-like symptoms common in inflammation-driven diseases. while other patients may have symptoms sometimes manifesting as heart problems, mental impairment, indigestion, diarrhoea, constipation, muscle pain, tender lymph nodes, said Jose Montoya, Professor of Infectious Diseases and lead author of the study. More than one million people in the US suffer from the CFS, also known as myalgic encephalomyelitis. It was reported earlier in 2017 that in Norway, a nation with a population of over five million, about 270 primary and secondary students dropped school due to the syndrome.

The disorder has no known cure or reliably effective treatments. For unknown reasons, the syndrome typically persists for decades, and likely hits among adolescents between the age of 15 and 20, and adults between 30 and 35, three of every four patients are women. Immune-modulating, antivirals and anti-inflammatory drugs may led to symptomatic improvement in some cases. However, no single pathogenic agent can be fingered, as the ultimate CFS trigger has yet been isolated, said Montoya. Analyzing blood samples from 192 patients and 392 healthy controls, the Stanford University researchers found levels of some immune-system signaling proteins or cytokines were lower in patients with mild CFS than in the control subjects, but were higher in patients with relatively severe CFS.

The findings were published in the Proceedings of the National Academy of Sciences released on July 31. The average age of the patients and controls was about 50, and the patients’ average duration of symptoms was more than 10 years. In addition, the researchers found that of the 51 cytokines they measured, the concentration of 17 cytokines tracked disease severity, 13 of which are pro-inflammatory. The authors of the study believe that their findings could improve the diagnosis and treatment of the disorder, including clinical trials to test the potential of immune modulator drugs as CFS therapies.
