Classical symptoms of both inflammatory and degenerative arthritides may contribute to neurogenic responses like wheal, flare, edema, and pain. Rheumatoid arthritis (RA) is an autoimmune disease with an immunogenetic background. Neurogenic inflammation has been considered to play an essential role in RA, in part because of the symmetrical involvement (cross-spinal reflexes) and the predominant involvement of the most heavily innervated small joints of the hands and the feet (highly represented in the hominiculus). In contrast, osteoarthritis (OA) is considered to arise as a result of degeneration of the hyaline articular cartilage, which secondarily results in local inflammation and pain. However, it is possible that the age-related and predominant (compared to nociceptive nerves) degeneration of the proprioceptive, kinesthetic and vasoregulatory nerves can represent the primary pathogenic events. This leads to progressive damage of tissue with extremely poor capacity for self-regeneration. Inflammation, be it primary/autoimmune or secondary/degenerative, leads to peripheral sensitization and stimulation, which may further lead to central sensitization, neurogenic amplification of the inflammatory responses and activation of the neuro-endocrine axis. Neuropeptides serve as messengers, which modulate and mediate the actions in these cascades. Accordingly, many neuropeptides have been used successfully as experimental treatments, most recently VIP, which effectively controlled collagen-induced arthritis in mice. Therefore, it can safely be concluded that better treatment/control of disease activity and pain can be achieved by blocking the cascade leading to initiation and/or amplification of inflammatory process combined with effects on central nociceptive and neuroendocrine responses.
炎症性和退行性关节炎的典型症状可能会引发诸如风团、潮红、水肿和疼痛等神经源性反应。类风湿性关节炎(RA)是一种具有免疫遗传背景的自身免疫性疾病。神经源性炎症被认为在类风湿性关节炎中起着至关重要的作用,部分原因在于其对称性受累(交叉脊髓反射)以及手部和足部神经支配最密集的小关节受累为主(在人体模型中高度体现)。相比之下,骨关节炎(OA)被认为是透明关节软骨退变的结果,继而导致局部炎症和疼痛。然而,本体感觉、运动感觉和血管调节神经与年龄相关的以及占主导地位的(与伤害性神经相比)退变可能代表了原发性致病事件。这会导致组织进行性损伤,且自我修复能力极差。炎症,无论是原发性/自身免疫性还是继发性/退行性,都会导致外周敏化和刺激,这可能进一步导致中枢敏化、炎症反应的神经源性放大以及神经内分泌轴的激活。神经肽作为信使,在这些级联反应中调节和介导各种作用。因此,许多神经肽已成功用于实验性治疗,最近的是血管活性肠肽(VIP),它有效控制了小鼠的胶原诱导性关节炎。所以,可以有把握地得出结论,通过阻断导致炎症过程起始和/或放大的级联反应,并结合对中枢伤害性感受和神经内分泌反应的影响,能够更好地治疗/控制疾病活动和疼痛。
