It has long been suspected that inflammation is central to its pathogenesis.<\/p>\n<p>Although only two cytokines were found to be different (TGF-\u03b2 higher and resistin lower) in ME\/CFS patients compared with controls, 17 cytokines correlated with ME\/CFS severity. Thirteen of these cytokines are proinflammatory and may contribute to many of the symptoms these patients experience for several years. Only CXCL9 (MIG) inversely correlated with fatigue duration.<\/p>\n<p><strong>Research abstract:<\/strong><\/p>\n<p>Although some signs of inflammation have been reported previously in patients with myalgic encephalomyelitis or chronic fatigue syndrome (ME\/CFS), the data are limited and contradictory. High-throughput methods now allow us to interrogate the human immune system for multiple markers of inflammation at a scale that was not previously possible. To determine whether a signature of serum cytokines could be associated with ME\/CFS and correlated with disease severity and fatigue duration, cytokines of 192 ME\/CFS patients and 392 healthy controls were measured using a 51-multiplex array on a Luminex system.<\/p>\n<p>Each cytokine\u2019s preprocessed data were regressed on ME\/CFS severity plus covariates for age, sex, race, and an assay property of newly discovered importance: nonspecific binding. On average, TGF-\u03b2 was elevated (P = 0.0052) and resistin was lower (P = 0.0052) in patients compared with controls. Seventeen cytokines had a statistically significant upward linear trend that correlated with ME\/CFS severity:<\/p>\n<p>CCL11 (Eotaxin-1), CXCL1 (GRO\u03b1), CXCL10 (IP-10), IFN-\u03b3, IL-4, IL-5, IL-7, IL-12p70, IL-13, IL-17F, leptin, G-CSF, GM-CSF, LIF, NGF, SCF, and TGF-\u03b1. Of the 17 cytokines that correlated with severity, 13 are proinflammatory, likely contributing to many of the symptoms experienced by patients and establishing a strong immune system component of the disease. Only CXCL9 (MIG) inversely correlated with fatigue duration.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cytokine signature associated with disease severity in chronic fatigue syndrome patients, by Jose G.
