The paper is concerned with an analysis of the results of the method of cryoheparinoprecipitation of plasma proteins in patients with immune complex pathology. The essence of the method is that in plasma cooling cryofibrinogens, cryoglobulins, immune complexes and other components of the complement system aggregate and precipitate. The process is potentiated by adding heparin to the plasma. ⋯ Signs of the abdominal, dermal and articular syndrome were eliminated in all the patients; the urinary syndrome was retained in half of the cases necessitating other therapeutic modalities. A CIC level investigated by a method of precipitation with 3.5% polyethylene glycol was not a criterion of assessment of the gravity of diseases: in cases of its increase before therapy initiation there was a clear tendency to a decrease and normalization by the end of treatment. In hemostasis investigation hypercoagulation activation and hyperfibrinogenemia were revealed in most of the patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A method of apheresis of plasma euglobulin fraction, cryoglobulins and Willebrand factor was developed. In one session of plasmapheresis 1500-1700 ml of patient's plasma were removed, fractionated and returned. The method was used in 2 patients with immune complex vasculitides. ⋯ A decrease in the content of plasma cryoglobulins, cryofibrinogen, and urine protein concentration (from 1.5 up to 0.03%) was noted in the other case. A possibility of the use of the method in other pathological conditions (DIC-syndrome, unstable angina, atherosclerotic angiopathy) accompanied by endothelial damage, was discussed. Willebrand factor multimers form complexes with low density lipoproteins therefore the removal of these complexes may be useful in the treatment of hypercholesteremia and atherosclerosis.
