title: Ig-Therasorb immunoadsorption for selective removal of human immunoglobulins in diseases associated with pathogenic antibodies of all classes and IgG subclasses, immune complexes, and fragments of immunoglobulins.
abstract: Therasorb immunoadsorption (IA), by selectively eliminating pathogenic substances from the circulation, allows for successful therapy of previously insufficiently treatable diseases. Molecules (specific polyclonal sheep antibodies) coupled to a matrix (Sepharose CL 4B) selectively bind plasma components in extracorporeal circulation. This procedure has been established in the treatment of various diseases. Examples are familial hypercholesterolemia (LDL-Therasorb) and selected autoimmune diseases (Ig-Therasorb). Ig-Therasorb IA has been performed in a variety of clinical indications, primarily in the treatment of autoimmune diseases. In most cases, Ig-Therasorb IA has been applied in patients who have failed to respond to conventional therapy with a high rate of clinical improvement. In defined groups of patients with autoimmune diseases and alloantibodies, immunoadsorption can now be considered an established therapeutic means. The fast and efficient removal of immunoglobulins obviously exceeds the efficiency of conventional plasma exchange by far. Autoimmune diseases could be induced by balanced and nonbalanced immunity. The importance of autoantibodies remains unclear, but the efficacy of Ig-Therasorb IA suggests a key role for them. In addition to the established indications for removal of immunoglobulins, there may be a number of promising new indications.
