There is currently a lack of information regarding neuropathic pain in the very early stages of spinal cord injury (SCI). In the present study, neuropathic pain was assessed using the Douleur Neuropathique 4 Questions (DN4) for the patient's worst pain within the first 5 days of injury (i.e., hyperacute) and on follow-up at 3, 6, and 12 months. Within the hyperacute time frame (i.e., 5 days), at- and below-level neuropathic pain were reported as the worst pain in 23% (n = 18) and 5% (n = 4) of individuals with SCI, respectively. Compared to the neuropathic pain observed in this hyperacute setting, late presenting neuropathic pain was characterized by more intense painful electrical and cold sensations, but less itching sensations. Phenotypic differences between acute and late neuropathic pain support the incorporation of timing into a mechanism-based classification of neuropathic pain after SCI. The diagnosis of acute neuropathic pain after SCI is challenged by the presence of nociceptive and neuropathic pains, with the former potentially masking the latter. This may lead to an underestimation of the incidence of neuropathic pain during the very early, hyperacute time points post-injury. TRIAL REGISTRATION: ClinicalTrials.gov (Identifier: NCT01279811) PERSPECTIVE: This article presents distinct pain phenotypes of hyperacute and late presenting neuropathic pain after spinal cord injury and highlights the challenges of pain assessments in the acute phase after injury. This information may be relevant to clinical trial design and broaden our understanding of neuropathic pain mechanisms after spinal cord injury.
目前,关于脊髓损伤(SCI)极早期神经病理性疼痛的信息匮乏。在本研究中,使用神经病理性疼痛4项问题量表(DN4)评估患者在损伤后前5天(即超急性期)最严重的疼痛情况,以及在3、6和12个月随访时的疼痛情况。在超急性时间范围内(即5天内),SCI患者中,损伤平面及以下的神经病理性疼痛分别被报告为最严重疼痛的比例为23%(n = 18)和5%(n = 4)。与在这种超急性情况下观察到的神经病理性疼痛相比,迟发性神经病理性疼痛的特点是疼痛性电感觉和冷感觉更强烈,但瘙痒感觉较少。急性和迟发性神经病理性疼痛之间的表型差异支持将时间因素纳入基于机制的SCI后神经病理性疼痛分类中。SCI后急性神经病理性疼痛的诊断受到伤害性疼痛和神经病理性疼痛同时存在的挑战,前者可能掩盖后者。这可能导致低估损伤后极早期、超急性时间点神经病理性疼痛的发生率。试验注册:ClinicalTrials.gov(标识符:NCT01279811)观点:本文呈现了脊髓损伤后超急性和迟发性神经病理性疼痛不同的疼痛表型,并强调了损伤后急性期疼痛评估的挑战。这些信息可能与临床试验设计相关,并拓宽我们对脊髓损伤后神经病理性疼痛机制的理解。
