Intensity of pain and biochemical changes in blood plasma in spinal cord trauma
Spinal Cord, 06/26/09

Yamamotova A et al. – After spinal cord injury, lower total cholesterol levels reflected more serious trauma intensity and HDL cholesterol predicted more intensive pain. Pain was less intensive for subjects responsible vs not responsible for their own injuries.

Methods

Cross-sectional, observational and longitudinal study
Analysis of relationship between pain intensity, plasma lipids and severity of spinal cord injuries in pts with paraplegia (11), tetraplegia (16) and polytrauma (15)
Focus on hospitalization period immediately following injury
Blood samples and assessment of pain intensity by visual analog scale immediately after pt transport to hospital, again 14 days after injury and before discharge from hospital
Measurement of biochemical parameters: total protein, albumin, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, glycemia, and C-reactive protein
Data analysis by injury type, state of unconsciousness immediately after injury, hemorrhage, measure of liability (self-inflicted injuries vs casualties), accident cause, and pre-injury cholesterol levels

Results

On day of injury, pain intensity correlated positively with HDL cholesterol
On day of discharge from hospital, pain intensity correlated positively with blood glucose levels
Diagnostic subgroups did not differ either in pain intensity or in pain dynamics during hospitalization
Total cholesterol level lowest in pts with polytrauma
In all pts, lowest total cholesterol level immediately after injury
HDL cholesterol highest after injury
