Serum Concentrations of Cytokines and Metallopeptidases During the Conservative and Minimal Invasive Treatment of Pain Caused by Lumbar Disc Herniation

Detailed Summary

Bulging of the intervertebral disc in the lumbar part of the spine is one of the most common degenerative changes of the spine in the elderly population, which causes various symptoms such as radicular pain. Possible mechanisms of radicular pain are mechanical compression of the intervertebral disc on the nerve and sterile local inflammation caused by proinflammatory factors. Depending on the degree of diagnosis, if conservative treatment is not successful, then treatment is focused on minimally invasive methods such as epidural steroid injection (ESI). The achieved neural blockade is believed to alter or interrupt nociceptive input, reflex mechanisms induced by afferent fibers, self-sustaining neuronal activity, and central neuronal activity. On the other hand, corticosteroids reduce inflammation by inhibiting pro-inflammatory mediators and causing a reversible local anesthetic effect. The aim of the research is to measure the concentrations of pro-inflammatory and anti-inflammatory cytokines and metallopeptidases in the serum before physical therapy, i.e. ESI, and two weeks and three months after the start of said therapies, then to examine the clinical status, intensity of pain and limitations of movement associated with pain in all three time points in order to determine the treatment outcomes after the mentioned therapies and examine the possible association of cytokine concentrations with the treatment outcomes and, last but not least, to determine the degree of the patient's psychophysical condition and quality of life before the mentioned therapies, two weeks and three months after the start of the therapies in order to examined possible associations with treatment outcomes and changes in cytokine and metallopeptidases concentrations.
