Circulating Adipokines in Predicting the Transition from Acute to Persistent Low Back Pain

Area of Science:

• Biomedical Science
• Pain Research
• Metabolic Syndrome

Background:

• Cytokines like tumor necrosis factor (TNF) are implicated in the transition from acute to chronic pain.
• Adipokines, cytokines from adipose tissue, are increasingly linked to obesity, inflammation, and chronic pain, yet their role in acute low back pain (LBP) recovery is understudied.

Purpose of the Study:

• To investigate the longitudinal changes in adipokines from the onset of acute LBP.
• To identify combinations of adipokines and other clinical features that predict recovery from LBP.

Main Methods:

• Retrospective analysis of acute LBP patients (recovered vs. unrecovered at 6 months) and controls.
• Measurement of TNF, IL-6, resistin, visfatin, adiponectin, leptin, and CRP in blood samples.
• Assessment of pain, disability, depression, and sleep via questionnaires at baseline and 6 months.

Main Results:

• Acute LBP patients exhibited higher TNF and CRP, and lower adiponectin compared to controls.
• Unrecovered LBP individuals showed higher TNF and lower baseline CRP and 6-month leptin.
• A combination of low CRP, high TNF, and depressive symptoms at baseline predicted poor LBP recovery.

Conclusions:

• Adipokines (leptin, resistin, visfatin, adiponectin) did not enhance the prediction of poor LBP outcome beyond TNF, CRP, and depressive symptoms.
• Further research is needed to explore the role of adipokines in LBP persistence, particularly in overweight or obese individuals.
