Hypothalamic-pituitary-adrenal axis function in traumatic spinal cord injury-related neuropathic pain: a case-control study.
This study aimed to investigate the hypothalamic-pituitary-adrenal (HPA) axis in spinal cord injury (SCI)-related neuropathic pain (NP) using dynamic adrenocorticotropic hormone (ACTH) stimulation tests. ⋯ This study demonstrated that, in chronic SCI patients with NP, basal cortisol levels are relatively higher compared to healthy controls, and that HPA axis can be activated with low- and standard-dose ACTH stimulation tests. Although NP following SCI was not significantly associated with hypo- or hypercortisolemia, either after low- or standard-dose ACTH stimulation test, the severity of NP during chronic SCI may be positively associated with HPA axis activity.
