[The removal efficiency of beta 2-microglobulin, alpha 1-microglobulin and alpha 1-acid glycoprotein by using dialyzers in the bloodstream and transference of endotoxin through membranes].
Retention of beta 2-microglobulin (beta 2-MG) has been indicated as one of the causes of hemodialysis-associated amyloidosis. Membranes with higher permeability (high-performance membrane) have recently been developed accordingly. Several dialyzers were tested by us in an attempt to study their removal efficiency of beta 2-MG and higher molecular substances of alpha 1-microglobulin (alpha 1-MG) and alpha 1-acid glycoprotein (alpha 1-AG), as well as transferring of endotoxin (ET) through membranes into bloodstream. The membranes subjected to our study were PMMA, CTA, PS, EVAL-C and CA. Removal efficiency of beta 2-MG through EVAL-C and CA was lower as compared with that through other membranes (P less than 0.05), while the EVAL-C showed relatively higher removal efficiency for alpha 1-MG and alpha 1-AG. Permeability for ET was not observed with all membranes studied herein.
