Artificial Excretion of Weakly Bound Middle Molecules by Hemoanadiafiltration

Abstract

The concept of a subtractive therapeutic intervention in several diseases (shock, acute liver, failure, poisoning) to remove toxic middle molecules (MM) has led to the devising of a particular ultrafiltration system (anadiafiltration) to clear weakly bound MM. Clinical hemoanadiafiltration (HADF) with a polyacrylonitrile filter and in vitro experiments with a series of marker substances, have shown HADF efficacy in clearing MM, irrespective of their molecular weight, with protein binding K between 50 and 150.
