Breve descrizione dei contenuti:
Background: Pain, either nociceptive or neuropathic (NP), is a common symptom in Charcot-Marie-Tooth (CMT) disease. Methods: We investigated small fibers involvement and its correlation with pain in different CMT subtypes through a systematic clinical and neurophysiological study. We enrolled 50 patients: 19 with duplication of PMP22 (CMT1A), 11 with mutation of MPZ (CMT1B, CMT2I/J or CMTDID), 12 with mutation of GJB1 (CMTX1) and 8 with mutation of MFN2 (CMT2A and CMT2A2B). Pain was rated with the 11-point Numerical Rating Scale and characterized through Neuropathic Pain Symptoms Inventory). Laser evoked potentials (LEPs) were recorded after right foot and hand stimulation and N2-P2 complex amplitude and latency were compared with those of 41 controls. Results: Overall pain prevalence was 36%. NP was present in 14,6 % of patients, with a length-dependent distribution in 85,7% of cases and it was significantly more frequent in CMT1A (p<0,001). Aδ fibers involvement greatly varies between CMT subtypes, reflecting differences in molecular pathology and pathophysiologic mechanisms. Prolonged N2 latency from foot stimulation was noted in 11 CMT1A patients, 5 of which report NP. MPZ-CMTs displayed different neurophysiological phenotypes and a very low prevalence of NP. LEPs were normal in all but one CMTX1 patients, although lower limbs N2-P2 amplitude was significantly reduced in males (p=0,043). MFN2-CMTs were NP free and LEPs recordings were all normal. NP strictly correlated with LEPs alterations (p=0,017). Conclusions: NP prevalence varies among CMTs subtypes and is mainly related to Aδ fibers impairment.
