Theory[edit | edit source]

The Open Medicine Foundation, with immunologist Mark Davis, and geneticist Lars Steinmetz, is currently investigating the replication of T cells in ME, which may indicate an autoimmune disease is present in some ME/CFS patients.[1]

Evidence[edit | edit source]

Evidence for autoimmunity in ME and CFS[edit | edit source]

Shows fibromyalgia 30-77% overlap, Hashimoto's thyroiditis 17-20%, POTS 11-40% overlap and family history of autoimmune conditions 18-41% overlap.

Many people with ME/CFS also have autoimmune conditions such as Fibromyalgia or Hashimoto's thyroiditis, or have a family history of autoimmune diseases.[2]POTS, or postural orthostatic tachycardia syndrome, can be initiated or maintained by autoantibodies as well, and POTS is common in people with ME. A number of different immune system abnormalities have been found in some patients with ME/CFS.[2]

One study found elevated cellular antigens in 83% of CFS patients.[3]

Autoimmune disease is one of several illnesses or conditions experienced alongside of ME/CFS.[4]

Samples from a large cohort (n=268) in Berlin, Germany and a smaller sample of patients treated with Rituximab (n=25) were measured against controls (n=168). Researchers found that antibodies against a neurotransmitter receptor were elevated in 29.5% of patients. Specifically, antibodies to ß2 adrenergic and M3 and M4 muscarinic cholinergic receptors, which are both G protein-coupled receptors (GCPRs). In patients receiving Rituximab, those who were responders had significantly lower levels of ß2 and M4 autoantibodies after treatment. The authors suggest that these autoantibodies could be biomarkers to those CFS patients most likely to respond to Rituximab treatment.[5][6]

Myalgic encephalomyelitis or M.E. has different diagnostic criteria to chronic fatigue syndrome; neurological symptoms are required but fatigue is an optional symptom.<ref name="ICP2011primer">{{Citation
