Neuropathic pain (NeP) is often under-recognized, resulting in poor pain management. Therefore, a Taiwan version of the 10-item Douleur Neuropathique 4 (DN4-T) questionnaire was developed to identify patients with NeP from a mixed population of patients with pain. ⋯ The DN4-T questionnaire has been reliably translated into Mandarin Chinese and can be used as a diagnostic tool for NeP in conjunction with clinical evaluation.

The chronic neuropathic pain-associated psychiatric disorders have seriously disturbed the quality of patients' life, such as depression and anxiety. Neuroinflammation in the hippocampus plays an important role in the neuropathic pain-associated depressive and anxiety disorders, but the underlying mechanism has not been thoroughly elucidated to date. The Nod-like receptor protein (NLRP)-1 inflammasome, which controls the production of pro-inflammatory cytokines, was broadly involved in the neuroinflammation-related diseases. ⋯ Functional inhibition of PKR suppressed the NLRP1 inflammasome activation and effectively attenuated the CCI-induced depression-like behaviors. These results indicate that the hippocampal PKR/NLRP1 inflammasome pathway play an important role in the development of the depressive behaviors after chronic neuropathic pain. Thus, interrupting this pathway might provide a novel therapeutic strategy for neuropathic pain-associated depressive disorders.

Clinical TrialHigh concentration of topical amitriptyline for treating chemotherapy-induced neuropathies.
Chemotherapy-induced peripheral neuropathy (CIPN) is a devastating pain condition of cancer therapy that may force chemotherapy dose reduction or discontinuation. Since treatment options for CIPN are quite limited, we investigated the effect of 10% amitriptyline cream on neuropathic pain. ⋯ Considering the limited efficacy of conventional systemic treatments in CIPN and their safety profile, 10% topical amitriptyline appears to be a good candidate for first-line CIPN therapy, allowing continuation of chemotherapy at effective doses. The results are worth to be confirmed in a placebo-controlled clinical trial.

Increased CXCL13 and CXCR5 in Anterior Cingulate Cortex Contributes to Neuropathic Pain-Related Conditioned Place Aversion.
Pain consists of sensory-discriminative and emotional-affective components. The anterior cingulate cortex (ACC) is a critical brain area in mediating the affective pain. However, the molecular mechanisms involved remain largely unknown. ⋯ Finally, superfusion of CXCL13 onto ACC slices increased the frequency and amplitude of spontaneous EPSCs. Pre-injection of Cxcr5 shRNA into the ACC reduced the increase in glutamatergic synaptic transmission induced by SNL. Collectively, these results suggest that CXCL13/CXCR5 signaling in the ACC is involved in neuropathic pain-related aversion via synaptic potentiation.
