|Title:||A pilot, randomized, double-blind, cross-over study of high cut-off versus high-flux dialysis membranes.||Austin Authors:||Lee, Darren;Haase, Michael;Haase-Fielitz, Anja;Paizis, Kathy ;Goehl, Hermann;Bellomo, Rinaldo||Affiliation:||Department of Nephrology, Austin Hospital, University of Melbourne, Melbourne, Victoria, Australia||Issue Date:||3-Sep-2009||Publication information:||Blood Purification 2009; 28(4): 365-72||Abstract:||High cut-off (HCO) membranes may increase beta(2)-microglobulin (beta2M) removal compared to standard high-flux membranes.Eight stable haemodialysis patients were enrolled in a prospective, randomized, double-blind, cross-over study and treated with HCO and high-flux membranes for 2 weeks each, between a 1-week washout period. Primary end point was serum beta2M removal. Secondary end points included serum albumin concentrations, albumin and small solute clearances.HCO membranes achieved significantly lower median post-dialysis beta2M concentration (10.8 vs. 14.2 mg/l; p = 0.003) and greater beta2M reduction ratio (62.3 vs. 51.0%; p < 0.002). Serum albumin decreased with HCO membranes (from 36 to 29.5 g/l; p = 0.018) but increased to 33.5 g/l after the washout period. Albumin clearance was significantly greater with HCO membranes (2.2 vs. 0.06 ml/min; p = 0.004). Urea reduction ratio was significantly lower with HCO membranes (64.8 vs. 71.5%; p < 0.001).beta2M removal was superior with HCO membranes. Reduction in serum albumin and lower small solute clearance require further investigations.||Gov't Doc #:||19729908||URI:||http://ahro.austin.org.au/austinjspui/handle/1/10878||DOI:||10.1159/000235961||URL:||https://pubmed.ncbi.nlm.nih.gov/19729908||Type:||Journal Article||Subjects:||Aged
