REmoval of Free Light Chains in Hemodialysis Patients Without Multiple Myeloma. A Crossover COmpaRison of Three Different dialyzERs
In Brief
A clinical study evaluating PMMA filter, HFR17 filter, and 1 other intervention for Complication of Hemodialysis. Completed, enrolled 20 participants across 1 site.
Detailed Summary
Immunoglobulin light chains are classified as middle molecule uremic toxins able to interact with B lymphocyte membranes leading to the activation of transmembrane signaling. The ensuing impairment of neutrophil function can contribute to the chronic inflammation state of uremic patients, and the increased risk of bacterial infections or vascular calcifications. The aim of this crossover observational study was to assess the difference in free light chain removal by three different hemodialysis filters in patients not affected by multiple myeloma. Free light chain removal was compared in the polymethylmethacrylate (PMMA) membrane Filtryzer BK-F, the polyphenylene HFR17 filter and the conventional polysulfone filter F7 High Performance dialysers (HPS). Twenty chronic hemodialysis patients were enrolled. The patients were randomized into two groups of treatment lasting six weeks each. The dialysis sessions checked were the midweek sessions and the blood was drawn at times 0, 120' and 240'. Kappa (k) and lambda (l) light chain levels, beta2microglobulin (β2M), C reactive protein (CRP) and albumin were checked.
