Acute spinal cord injury (ASCI) is a devastating event that can have a profound impact on the lives of patients and their families. While no definitive medical treatment exists, the role of methylprednisolone (MP) in the management of ASCI and other spinal cord pathologies has been investigated in depth; however, its use remains contentious. While MP initially showed promise in the efficacy of ASCI treatment, more recent studies have questioned its use citing numerous systemic adverse effects. Pharmacologic treatments in this area are poorly understood due to the scarcity of knowledge surrounding the pathophysiology and heterogeneity of patients presenting with these conditions. Despite these shortcomings and due to the lack of alternative treatment options, MP is still widely used by physicians.
We review prior and current literature on the use of MP treatment for ASCI patients with a discussion of novel drug delivery systems that have demonstrated the potential to improve MP's bioavailability at the site of injury while minimizing systemic side effects. In addition, current views on the role of MP and dexamethasone in metastatic spinal cord compression and postoperative infection are reviewed.
While some data support benefits in the use of steroids on spinal cord pathology, extensive research suggests at best limited effects and an unresolvable risk/benefit problem.
At present, evidence regarding use of dexamethasone for MSCC is contentious, especially regarding dose regiments. Ultimately, further investigation into the use of steroids is required to determine its utility in treating patients with spinal cord pathology.
急性脊髓损伤(ASCI)是一种破坏性事件,会对患者及其家庭的生活产生深远影响。虽然目前尚无明确的医疗治疗方法,但甲泼尼龙(MP)在 ASCI 和其他脊髓病理疾病的治疗中的作用已经得到了深入研究;然而,其应用仍然存在争议。虽然 MP 在 ASCI 治疗的疗效方面最初显示出了希望,但最近的研究对其应用提出了质疑,指出其存在许多全身不良反应。由于对这些疾病患者的病理生理学和异质性的了解甚少,该领域的药物治疗方法仍知之甚少。尽管存在这些缺陷,并且由于缺乏替代治疗方案,MP 仍被医生广泛使用。
我们回顾了关于 MP 治疗 ASCI 患者的既往和当前文献,并讨论了新型药物输送系统,这些系统已被证明具有提高损伤部位 MP 生物利用度的潜力,同时最大限度地减少全身副作用。此外,还回顾了当前关于 MP 和地塞米松在转移性脊髓压迫和术后感染中的作用的观点。
虽然一些数据支持在脊髓病理中使用类固醇的益处,但广泛的研究表明,其效果最好是有限的,而且存在无法解决的风险/收益问题。
目前,关于地塞米松用于 MSCC 的证据存在争议,特别是关于剂量方案。最终,需要进一步研究类固醇的应用,以确定其在治疗脊髓病理患者中的效用。
