AbstractGranulocyte colony-stimulating factor (G-CSF) is a major growth factor in the activation and differentiation of granulocytes. This cytokine has been widely and safely employed in different conditions over many years. In this translational study, G-CSF is administered to 19 patients with chronic motor complete spinal cord injury, and outcomes are reported. All 19 patients received subcutaneous G-CSF (5 µg/kg per day) for 5 days and were followed for at least 6 months. The American Spinal Injury Association (ASIA) scale was used for motor and sensory assessment, and the International Association of Neurorestoratology-Spinal Cord Injury Functional Rating Scale (IANR-SCIFRS) and the Spinal Cord Independence Measure (SCIM) III were used to assess improvements in the ability to perform basic daily tasks. At the 6-month follow-up, upper extremity motor scores improved by 10, which was statistically significant (p = 0.007), whereas there were no significant changes in lower extremity motor scores. Also, the median of light touch sensory scores improved by 5 (p = 0.001). Pinprick sensory scores significantly improved (p = 0.002). The median increment in SCIM III total score was 7 (p = 0.001). The improvements in bladder and bowel management as well as moderate distance mobility subscales were also significant (p < 0.05). Total IANR-SCIFRS scores changed from 17 to 32, which was statistically significant (p = 0.001); again the bladder and bowel management subscale improvements were statistically significant (p < 0.05). Mild side effects of the G-CSF treatment such as bone pain, rash, fever, neuropathic pain, and spasticity were noted in a few patients; all of them resolved after 1 week. Our results indicate that G-CSF administration is a safe process and is associated with neurological as well as functional improvement. This manuscript is published as part of the International Association of Neurorestoratology (IANR) supplement issue of Cell Transplantation.
