['To show that heparin cryoprecipitation (HCP), an in vitro method of plasma purification, reduces the levels of in vivo modified proteins and non-traditional risk factors from plasma of atherosclerotic hemodialysis (HD) patients.', 'HCP was applied to plasma obtained from HD patients and controls, forming a precipitate--cryogel. Levels of fibrinogen, albumin, CRP, TNF-alpha, IL-6, advanced oxidation protein products, carbonylated fibrinogen and carbonylated albumin were determined in plasma before and after applying HCP and in the cryogel.', 'Treatment of HD plasma with HCP, beyond the significant reduction of the increased levels of all the above-mentioned molecules, reduced fibrinogen, TNF-alpha, carbonylated fibrinogen and carbonylated albumin to control levels which were simultaneously found in the cryogel.'] Does heparin cryoprecipitation reduce plasma levels of non-traditional risk factors for atherosclerosis in vitro?
