    Fibromyalgia is characterized by widespread pain, sensory hypersensitivities, and peripheral nerve dysfunction affecting 40%-50% of patients.

  • 2

    Autoantibodies, particularly IgG, from fibromyalgia patients can induce hypersensitivity to mechanical and cold stimuli in animal models.

  • 3

    The study found that patient IgG binds to dorsal root ganglia structures, correlating with the severity of sensory symptoms in fibromyalgia.

  • 4

    Microneurography revealed significant sensory abnormalities in Aβ SA fibres of fibromyalgia patients compared to healthy controls.

  • 5

    The findings suggest a potential role of autoantibodies in altering sensory neuron function, contributing to fibromyalgia symptoms.
