Low-Density Lipoprotein Adsorption by Centrifugal Plasma Separation Can Shorten Treatment Time.

ABSTRACT: Low-density lipoprotein (LDL) apheresis is effective for nephrotic syndrome in drug-resistant focal segmental glomerulosclerosis (FSGS). Dextran sulfate adsorption of LDL (DSAL) is widely used for this purpose. The Liposorber LA-15 system performs DSAL by membrane plasma separation (mDSAL) using an MA-03 plasma purification device. However, sufficient blood flow (Qb) frequently cannot be obtained from a peripheral vein with mDSAL. The recommended plasma filtration flow rate (Qf) when using the OP-05W membrane plasma separator is no more than 1/3 of Qb, giving plasma removal efficiency (PRE) of about 30%. In contrast, the centrifugal blood component separator Spectra Optia has PRE of 87-92.5% because centrifugal separation enables effective separation of plasma components even at low Qb. He
