Hyperexcitable C Nociceptors in Fibromyalgia

  [ 10 votes ]   [ Discuss This Article ]
By Jordi Serra, MD, et al. • www.ProHealth.com • December 9, 2013


Editor's comment:  Nociceptors are nerve cells that respond to potentially damaging stimuli by sending  signals – usually perceived as pain – to the brain and spinal cord.  In this study, researchers found that the function of certain nociceptors is abnormal in most people with fibromyalgia. 

Abstract:

Objective: To test the hypothesis that peripheral C nociceptor function may be abnormal in fibromyalgia and that C nociceptor dysfunction may contribute to the symptoms reported by these patients.

Methods: Microneurography was used to record from C nociceptors of 30 female patients meeting criteria for fibromyalgia and compared with recordings from 17 female patients with small fiber neuropathy and 9 female controls.

Results: We obtained stable recordings from 186 C nociceptors in the fibromyalgia group, 114 from small fiber neuropathy patients, and 66 from controls.

  • The mechano-sensitive nociceptors in the fibromyalgia patients behaved normally, but the silent nociceptors in 76.6% of fibromyalgia patients exhibited abnormalities.

  • Spontaneous activity was detected in 31% of silent nociceptors in fibromyalgia, 34% in small fiber neuropathy, and 2.2% in controls.

  • Sensitization to mechanical stimulation was found in 24.2% of silent nociceptors in fibromyalgia, 22.7% in small fiber neuropathy, and 3.7% in controls.

  • Abnormally high slowing of conduction velocity when first stimulated at 0.25 Hz was more common in fibromyalgia.

Interpretation: We show for the first time that the majority of fibromyalgia patients have abnormal C nociceptors. Many silent nociceptors exhibit hyperexcitability resembling that in small fiber neuropathy, but high activity-dependent slowing of conduction velocity is more common in fibromyalgia patients, and may constitute a distinguishing feature. We infer that abnormal peripheral C nociceptor ongoing activity and increased mechanical sensitivity could contribute to the pain and tenderness suffered by patients with fibromyalgia.
