Abstract: Neuropathic pain (NP), a common secondary complication following spinal cord injury (SCI), presenting at or below the level of injury is largely refractory to current pharmacological, physical, and surgical treatments. Previous studies have demonstrated the promising value of cell therapy including adrenal chromaffin cells that have the capacity to act as mini-pumps that release amines and peptides for alleviating chronic pain. The paper presents the cases of two gentlemen suffering from severe central NP after thoracic SCI. Six months after chromaffin cell intrathecal injection, their pain relieved significantly. The results demonstrated the preliminary therapeutic efficacy of chromaffin cell transplants in people with NP, and support further research of this treatment strategy for the management of intractable chronic pain due to SCI.
