摘要:

富血小板血浆和骨髓浓缩物在治疗神经系统疾病方面已显示出了潜力,但两者联合治疗脊髓损伤的信息有限。为评估自体富血小板血浆联合骨髓浓缩物治疗脊髓损伤的安全性和有效性。该回顾性病例系列纳入7例通过静脉内和鞘内注射联合使用自体富血小板血浆和骨髓浓缩物治疗的脊髓C3-T11损伤的患者,以Oswestry残疾指数对治疗前后的临床功能结局进行评估,并观察不良反应。患者治疗后并发症轻微且少见,仅1例患者出自限性头痛和主观记忆障碍。2例不完全性颈髓损伤患者在治疗后12和2个月Oswestry残疾指数分别降低了40%和28%,说明其残疾程度得到了改善。7例观察可见,鞘内/静脉内联合自体富血小板血浆 和骨髓浓缩物治疗脊髓损伤患者未见现严重并发症,并且可能具有一定的临床益处。

Abstract: Administration of platelet rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) has shown some promise in the treatment of neurological conditions; however, there is limited information on combined administration. As such, the purpose of this study was to assess safety and functional outcomes for patients administered combined autologous PRP and BMAC for spinal cord injury (SCI). This retrospective case series included seven patients who received combined treatment of autologous PRP and BMAC via intravenous and intrathecal administration as salvage therapy for SCI. Patients were reviewed for adverse reactions and clinical outcomes using the Oswestry Disability Index (ODI) for up to 1 year, as permitted by availability of follow-up data. Injury levels ranged from C3 through T11, and elapsed time between injury and salvage therapy ranged from 2.4 months to 6.2 years. Post-procedure complications were mild and rare, consisting only of self-limited headache and subjective memory impairment in one patient. Four patients experienced severe disability prior to PRP combined with BMAC injection, as evidenced by high (> 48/100) Oswestry Disability Index scores. Longitudinal Oswestry Disability Index scores for two patients with incomplete SCI at C6 and C7, both of whom had cervical spine injuries, demonstrated a decrease of 28–40% following salvage therapy, representing an improvement from severe to minimal disability. In conclusion, intrathecal/intravenous 
co-administration of PRP and BMAC resulted in no significant complications and may have had some clinical benefits. Larger clinical studies are needed to further test this method of treatment for patients with SCI who otherwise have limited meaningful treatment options. This study was reviewed and approved by the OhioHealth Institutional Review Board (IRB No. 1204946) on May 16, 2018.
