Abstract

Introduction. Remote ischemic preconditioning (RIPC) is a promising intervention for protecting organs and tissues from damage.

The aim of this study was to evaluate the diagnostic efficacy of angioneuroprotective biomarkers in patients with extrapyramidal movement disorders undergoing magnetic resonance-guided focused ultrasound (MRgFUS) thermocoagulation.

Materials and Methods. 42 patients were enrolled in a prospective, randomized, blinded study with an active control (sham RIPC). Prior to the procedure, patients were randomized into either the RIPC group (cuff pressure set at systolic blood pressure + 50 mm Hg, n=21) or the sham RIPC group (cuff pressure set at diastolic blood pressure, n=21). The protocol in both groups consisted of three 5-minute cycles of the cuff inflation (preconditioning or its imitation) each followed by a 5-minute rest intervals. Levels of biomarkers (TRIM72, S100B, ubiquitin, Lp-PLA2, endothelin-1) were measured in blood serum before and 1 hour after MRgFUS procedure.

Results. Comparison of post-procedural biomarker levels revealed statistically significant differences: the S100B levels were higher in the sham RIPC group (1.34 ng/mL) compared to the RIPC group (0.44 ng/mL, p<0.001) and the ubiquitin level (5.8 ng/mL) were also higher than in the RIPC group (4.73 ng/mL) (p = 0.008). These findings indicate that prior RIPC is associated with suppression of biomarkers of neuroglial damage (S100B) and proteolytic stress (ubiquitin) released in response to thermocoagulation.

Conclusion. RIPC is associated with reduced levels of S100B and ubiquitin during MRgFUS thermocoagulation, demonstrating a cytoprotective effect by mitigating blood-brain barrier and neuronal damage.
