Observational study quantifies cytokines in chronic low back pain cohort, indicating inflammation's role in pain and functional status.
Key Points
Higher concentrations of IL-6, IL-1ra, and Leptin were associated with increased pain and disability severity, highlighting the impact of inflammation.
Out of 936 participants, cytokine levels exceeded those found in healthy populations, particularly for TNF and Leptin in specific demographics.
Methods included measuring plasma cytokine concentrations via immunoassays, assessing pain levels with validated scales and the Oswestry Disability Index.
Findings suggest differences in inflammatory markers across age and sex, emphasizing the need for targeted therapies addressing inflammation.
