Immune and signaling markers in blood and spinal fluid during spinal cord stimulation for neuropathic pain

Analysis of Selected Biochemical Parameters in Cerebrospinal Fluid and Peripheral Blood in the Treatment of Neuropathic Pain Using Spinal Cord Stimulation (SCS) Assessment of the Mechanism of Action of SCS and the Potential of Biochemical Studies in Therapy Planning and Monitoring

Not applicable Interventional Jan Biziel University Hospital No 2 in Bydgoszcz · NCT07153211

This project tests whether measuring immune and signaling molecules in blood and cerebrospinal fluid can help explain and predict how spinal cord stimulation works for adults with chronic neuropathic pain.

What this trial studies

Participants undergoing spinal cord stimulation will have blood and cerebrospinal fluid sampled to measure selected inflammatory mediators and signaling molecules such as IL-1β, IL-6, IL-17, IL-33, BDNF, VEGF, and GABA. Concentrations of these markers will be correlated with clinical status, pain outcomes, and different stimulation types to identify patterns linked to treatment response. The study also examines the potential role of glial cell–related signals and differences between stimulation modalities. Findings aim to support biomarker development, optimization of stimulation parameters, and complementary pharmacotherapy strategies.

Who should consider this trial

Good fit: Adults aged 18–80 with chronic neuropathic pain due to persistent spinal pain syndrome (PSPS) or complex regional pain syndrome (CRPS) lasting at least six months who are undergoing or being considered for SCS are the intended participants.

Not a fit: Patients with active infection, malignant tumors, substance dependence, serious psychiatric disorders, or who are pregnant are excluded and unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help doctors predict which patients and which stimulation settings are most likely to reduce pain and allow more personalized neuromodulation.

How similar studies have performed: Prior smaller studies report that SCS can alter inflammatory mediators and glial activity, but robust, clinically useful predictive biomarkers have not yet been consistently validated.
