[Cryohemosorption--a method of removal of lipoprotein-antibody immune complexes and other atherogenic substances in patients with atherosclerosis].

: The efficacy of extracorporeal cryohemosorption was estimated in the treatment of atherosclerotic patients in terms of the autoimmune theory of the pathogenesis of this disease. There was a slight decrease in the plasma levels of total cholesterol and triglycerides, there was over 2-fold reduction in the plasma levels of fibrinogen and fibronectin. All major components of apo B-containing lipoproteins and immunoglobulin G were found as part of the cryoprecipitate. An extremely high concentration of lipid hydroperoxides in the precipitate suggest that cryoprecipitation removes not only autoimmune complexes, but highly-atherogenic peroxide-modified lipoproteins. The three-fold decrease in the levels of lipoprotein-antibody complexes resulted in lower atherogenicity of apo B-containing lipoproteins. It is suggested that the mechanism responsible for beneficial clinical action of cryohemosorption sessions is largely associated with the removal of autoimmune lipoprotein-antibody complexes and peroxide-modified apo B-containing lipoproteins than correction of lipid metabolism.
