N2 - In this multicenter cross-sectional study, we determined sensory profiles of patients with (NL-1) and without neuropathic pain (NL-0) after nerve lesion and assessed immune-related systemic gene expression. Patients and matched healthy controls filled in questionnaires and underwent neurological examination, neurophysiological studies, quantitative sensory testing, and blood withdrawal. Neuropathic pain was present in 67/95 (71%) patients (NL-1). Tactile hyperalgesia was the most prominent clinical sign in NL-1 patients (P , 0.05). Questionnaires showed an association between neuropathic pain and the presence of depression, anxiety, and catastrophizing (P , 0.05 to P , 0.01). Neuropathic pain was frequently accompanied by other chronic pain (P , 0.05). Quantitative sensory testing showed ipsilateral signs of small and large fiber impairment compared to the respective contralateral side, with elevated thermal and mechanical detection thresholds (P , 0.001 to P , 0.05) and lowered pressure pain threshold (P , 0.05). Also, more loss of function was found in patients with NL-1 compared to NL-0. Pain intensity was associated with mechanical hyperalgesia (P , 0.05 to P , 0.01). However, quantitative sensory testing did not detect or predict neuropathic pain. Gene expression of peptidylglycine a-amidating monooxygenase was higher in NL patients compared with healthy controls (NL-1, P , 0.01; NL-0, P , 0.001). Also, gene expression of tumor necrosis factor-a was higher in NL-1 patients compared with NL-0 (P , 0.05), and interleukin-1ß was higher, but IL-10 was lower in NL-1 patients compared with healthy controls (P , 0.05 each). Our study reveals that nerve lesion presents with small and large nerve fiber dysfunction, which may contribute to the presence and intensity of neuropathic pain and which is associated with a systemic proinflammatory pattern.
