FIVE YEARS FOLLOW-UP OBSERVATION ON PATIENTS WITH SPINAL CORD INJURY TREATED WITH OLFACTORY ENSHEATHING CELL TRANSPLANTATION
Journal Title: Asian Pacific Journal of Microbiology Research (APJMR) - Year 2017, Vol 1, Issue 2
Abstract
Olfactory ensheathing cell transplantation (OECT) has been applied to treat patients with spinal cord injury (SCI). This study was to investigate the long-term curative efficacy and safety of OECT by observing the long-term alterations of sensory level (SL), muscle strength, neural function and individual self-evaluations. Methods & Materials: The olfactory ensheathing cells used by this study were derived from allogeneic embryonic olfactory bulb induction. We observed 24 patients with SCI (male/female 20/4; average age 32.4 years, age range 19~45) who were treated with OECT in our hospital from September 2005 to March 2010. Neural function was evaluated based on the ASIA scores. Follow-up time ranged from 0.5 to 5.2 years, averagely was 3.2 years. Statistical analysis was done using ANOVA. Results: After OECT no apparent complications were found in the 24 patients. Among 11 patients with complete paralysis, 10 patients’ SL moved downwards by 1-2 spinal segments, and 1 patient’s SL no changed. Among 13 patients with incomplete paralysis, 11 patients’ SL descended by two spinal segments, 2 patients’ SL by three spinal segments and 1 of the 2 showed improvement of flexor function and emergence of thumb long extensor dorsiflexion movement (muscle strength 2 degrees). MRI showed no mass or cavity formation in the sites of OECT. 2 patients gave OECT excellent self-evaluation, 9 good, 12 poor, and 1 very poor. The rate of excellent and good self-evaluation accounted for 50%. The ASIA scores before and after OECT had not obviously difference (P<0.05). Conclusion: Though OECT is safe for SCI treatment, its long-term therapeutic effect is not ideal. This therapy still needs further observation and more exploration.
