BACKGROUND: Pain is the major cause of disability in disc induced lumbosacral radiculopathy (LSR) and is related to neurotrophins mainly brain derived neurotrophic factor (BDNF). However, to our knowledge evaluating serum BDNF in disc induced LSR has not been reported before. This study was done to investigate serum BDNF in LSR patients and its relation to pain severity and functional disability.
METHODS: This case-control study included 40 disc induced LSR patients and 40 age and sex matched healthy subjects. All patients were subjected to neurological examination, electrophysiological evaluation, pain severity assessment using numerical rating scale (NRS) and functional disability assessment using Modified Oswestry Low Back Pain Disability Index (ODI) and Maine-Seattle Back Questionnaire (MSBQ). According to Douleur neuropathique 4 (DN4) questionnaire, patients were divided into those with neuropathic pain and those with non-neuropathic pain. Serum BDNF was measured by enzyme-linked immunosorbent assay in all participants.
RESULTS: Serum BDNF was significantly higher in LSR patients than in healthy controls (U=272.5, P<0.001). Moreover, serum BDNF was significantly higher in those with neuropathic pain compared to those with non-neuropathic pain (U=35, P=0.03). Serum BDNF had a significant positive correlation with NRS score among those with acute pain (rs=0.537, P=0.026), however there was no significant correlation among those with chronic pain. Furthermore, BDNF had no significant correlation with modified ODI and MSBQ.
CONCLUSION: Increased serum BDNF may be associated with neuropathic pain and acute pain severity in disc induced LSR. However, it may not be related to chronic pain severity or functional disability.
