Dissertation/Thesis Abstract

Entwicklung eines Großtiermodells zur Charakterisierung der Permeabilität von Fraktionierungsmembranen für die Lipoproteinapherese
by Lange, Florian, Ph.D., Bayerische Julius-Maximilians-Universitaet Wuerzburg (Germany), 2018, 71; 27766777
Abstract (Summary)

Technical problems during clinical lipid apheresis interfere with fractionator performance. Therefore, a large animal model was established to characterize a new plasma fractionation membrane. Four sheep were randomized, controlled, and crossover subjected to double filtration lipoprotein apheresis with three specimens of FractioPES having slightly different HDL sieving coefficients (SK) (FPESa, 0.30, FPESb, 0.26, and FPESc, 0.22) versus a control fractionator (EVAL). SK and reduction ratios were determined for LDL, HDL, fibrinogen, IgG, and albumin. Compared to EVAL (0.42 � 0.04 to 0.74 � 0.08) and FPESa (0.36 � 0.06 to 0.64 � 0.04), SK for HDL were lower (P < 0.05) with FPESc (0.30 � 0.04 to 0.49 � 0.10). Fibrinogen SK were higher (P < 0.05) with EVAL (0.02 � 0.01 to 0.40 � 0.08) compared to FPESb (0.05 � 0.02 to 0.26 � 0.34) and FPESc (0.01 � 0.01 to 0.21 � 0.16). No further differences were determined. The animal model distinguished between minor differences in fractionation membrane permeability, demonstrating equivalent sieving of FPESa and EVAL and slightly inferior permeability of FPESb and FPESc.
