IFN-γ Correlations with Pain Assessment, Radiological Findings, and Clinical Intercourse in Patient after Lumbar...

Area of Science:

• Neuroscience
• Immunology
• Orthopedic Surgery

Background:

• Sciatica pain, often caused by lumbar disc herniations, is frequently treated with microdiscectomy.
• Interferon gamma (IFN-γ), a pro-inflammatory cytokine, has been implicated in pain development, but its specific role in radicular pain remains unclear.

Purpose of the Study:

• To investigate the relationship between pain reduction following lumbar microdiscectomy and serum levels of interferon gamma (IFN-γ).
• To explore the potential role of IFN-γ in the pathophysiology of sciatica and radicular pain.

Main Methods:

• Clinical and immunoenzymatic assessments were conducted on 27 patients before and 3 months after lumbar microdiscectomy.
• Pain was evaluated using the Numeric Rating Scale (NRS), McGill Pain Questionnaire (SF-MPQ), Oswestry Disability Index (ODI), and Beck Depression Inventory (BDI).
• Plasma concentrations of IFN-γ were measured using an immunoenzymatic method.

Main Results:

• Significant positive correlations were observed between pain scores (NRS, PRI) and IFN-γ levels both before and after surgery, indicating that lower pain is associated with lower IFN-γ.
• Patients with nerve compression showed significantly lower IFN-γ levels before and after surgery compared to those without nerve compression.

Conclusions:

• A decrease in pain after lumbar microdiscectomy is correlated with reduced serum IFN-γ levels.
• Elevated IFN-γ levels were observed in patients without significant nerve compression, suggesting a complex role in radicular pain mechanisms.
