ABSTRACT
BACKGROUND:
Accumulation of middle molecules is thought to have adverse effects in patients with acute kidney injury (AKI). Elimination of middle molecules by non-convective means, i.e. hemodialysis, remains difficult. The aim of the study was to investigate the removal characteristics of a new high permeability membrane in AKI patients undergoing extended dialysis (ED). PATIENTS ANDMETHODS:
We performed a prospective, crossover study comparing the EMiC2 dialyzer (1.8 m(2), FMC, Germany) and AV 1000S (1.8 m(2), FMC) in 11 critically ill patients with AKI. ß2-Microglobulin, cystatin c, creatinine, and urea were measured before and after 0.5, 5.0 and 10 h of ED. Serum reduction ratios, dialyzer clearances, and mass in the total collected dialysate were determined.RESULTS:
Dialyzer clearance of ß2-microglobulin (EMiC2 52 ± 1.7 ml/min, AV 1000S 41.7 ± 1.5 ml/min, p = 0.0002) and cystatin c (EMiC2 47.2 ± 1.2 ml/min, AV 1000S 34.2 ± 2.3 ml/min, p < 0.0001) was markedly different, as was the reduction of serum levels of ß2-microglobulin (EMiC2 54.3 ± 3.6%, AV 1000S 39.1 ± 4.5%, p = 0.025) and cystatin c (EMiC2 38.9 ± 2.6%, AV 1000S 28.0 ± 3.9%, p = 0.043). Additionally, we observed a higher total amount of these substances in the collected dialysate. There was no significant difference in the total amount of albumin eliminated per treatment.CONCLUSION:
The new EMiC2 dialyzer enhances removal of middle molecules without an increase in albumin loss. The clinical relevance of this finding needs to be determined.
