Efficacy and Safety of Super High-Flux Hemodialysis in Maintenance Dialysis Patients. SHINE-RLS (Super High-flux Dialysis Improves Neuro-symptoms and Efficacy in Restless Legs Syndrome)

Brief Summary

Patients with end-stage kidney disease (ESKD) rely on maintenance hemodialysis. While high-flux hemodialysis improves small solute clearance, its removal of middle-molecule uremic toxins (e.g., α1-microglobulin \[α1-MG\]) remains insufficient, contributing to symptoms such as restless legs syndrome (RLS), pruritus, and poor sleep quality, which are also linked to increased cardiovascular risk. In this study, the investigators evaluate whether using a "Super High-Flux" dialyzer (a Type V high-performance dialyzer) during hemodialysis can safely improve the removal of middle-molecule uremic toxins-specifically α1-microglobulin (α1-MG)-and relieve RLS symptoms in maintenance hemodialysis patients.
