In addition, in an “unbiased” metabolomics study using mass spectrometry, metabolites that differed most between 17 patients with ME/CFS and 15 healthy participants involved pathways harvesting energy from glucose, fatty acids, and amino acids.

The finding, suggestive of a general hypometabolic state, corresponds to another recent study published in the Proceedings of the National Academy of Sciences. The specific metabolites differed between the two studies, but, Dr Komaroff said, “it’s consistent. It says that some types of metabolic pathways are downregulated in this illness, whereas others like those involving immunity and inflammation are upregulated.”

FORT LAUDERDALE, FL — New research adds to growing evidence that the illness commonly known as chronic fatigue syndrome is biologically based, researchers report here at the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (IACFSME) research and clinical conference. Some of the abnormalities identified suggest potential clinical diagnostic tests and targeted treatments.

The condition, now called myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) by US government bodies, has long confounded the medical community because, although patients may be severely debilitated and exhibit numerous abnormal physical findings, no specific biomarker has been found to conclusively make the diagnosis.
