Exploring neuropathic symptoms in a large cohort of Italian patients with different peripheral nervous system diseases

Neuropathic pain is a disabling symptom frequently reported by patients with neuropathies. Pain-questionnaires are the best way to investigate it. Neuropathic Pain Symptom Inventory (NPSI) questionnaire specifically assesses the different symptoms of neuropathic pain. The objective of this study was to evaluate, through the NPSI, the different neuropathic painful symptoms in a population of neuropathic patients. 277 patients with different neuropathies were evaluated with the NPSI to investigate the prevalence of the different neuropathic symptoms. Neuropathic pain was reported by 94.4% of the patients, resulting to be common not only in diabetic and iatrogenic neuropathies, but also in hereditary, paraproteinemic, and idiopathic neuropathies. The majority of our patients (88.6%) presented paresthesia/dysesthesia. The results of our study point out the difference in the occurrence of the painful symptoms. A scale able to discriminate distinct types of neuropathic pain may provide clinicians with adequate therapeutic choices in the daily practice
