Its pathogenesis is poorly understood. <a href=\"https:\/\/en.wikipedia.org\/wiki\/GDF15\" target=\"_blank\" rel=\"noopener noreferrer\">GDF15<\/a> is a circulating protein secreted by cells in response to a variety of stressors. The receptor for GDF15 is expressed in the brain, where its activation results in a range of responses. Among the conditions in which circulating GDF15 levels are highly elevated are mitochondrial disorders, where early skeletal muscle fatigue is a key symptom. We hypothesised that GDF15 may represent a marker of cellular stress in ME\/CFS.<\/p>\n<p><strong>Methods:<\/strong><br \/>\nGDF15 was measured in serum from patients with ME\/CFS (n\u2009=\u2009150; 100 with mild\/moderate and 50 with severe symptoms), \u201chealthy volunteers\u201d (n\u2009=\u2009150) and a cohort of patients with multiple sclerosis (n\u2009=\u200950).<\/p>\n<p><strong>Results:<\/strong><br \/>\n<a href=\"https:\/\/wames.org.uk\/cms-english\/circulating-levels-of-gdf15-in-patients-with-me-cfs\/feet-bed\/\" rel=\"attachment wp-att-23408\"><img data-recalc-dims=\"1\" decoding=\"async\" class=\"alignright wp-image-23408 size-medium lazyload\" data-src=\"https:\/\/i0.wp.com\/wames.org.uk\/cms-english\/wp-content\/uploads\/2019\/12\/feet-bed.jpg?resize=300%2C219&#038;ssl=1\" alt=\"\" width=\"300\" height=\"219\" data-srcset=\"https:\/\/i0.wp.com\/wames.org.uk\/cms-english\/wp-content\/uploads\/2019\/12\/feet-bed.jpg?resize=300%2C219&amp;ssl=1 300w, https:\/\/i0.wp.com\/wames.org.uk\/cms-english\/wp-content\/uploads\/2019\/12\/feet-bed.jpg?resize=150%2C109&amp;ssl=1 150w, https:\/\/i0.wp.com\/wames.org.uk\/cms-english\/wp-content\/uploads\/2019\/12\/feet-bed.jpg?w=528&amp;ssl=1 528w\" data-sizes=\"(max-width: 300px) 100vw, 300px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 300px; --smush-placeholder-aspect-ratio: 300\/219;\" \/><\/a>Circulating GDF15 remained stable in a subset of ME\/CFS patients when sampled on two occasions\u2009~\u20097\u00a0months (IQR 6.7\u20138.8) apart, 720\u00a0pg\/ml (95% CI 625\u2013816) vs 670\u00a0pg\/ml (95% CI 598\u2013796),\u00a0P\u2009=\u20090.5.
