[Comparative studies of immunologic characteristics in plasmapheresis and hemosorption in patients with purulent diseases of the lungs and pleura].

The article deals with the comparative characteristics of the changes in immunological indices in 40 patients with non-specific purulent diseases of the lungs and pleura when plasmapheresis and hemosorption were included in the complex of therapeutic measures. The changes were found to be hetero-directional in character: a non-specific effect of immunostimulation in hemosorption, and immunodepression, particularly marked in the first 24 hours, in plasmapheresis. The post-aggressive reaction after plasmapheresis is either absent or delayed significantly, which makes it possible to conduct detoxification in extremely grave conditions of the patients without making the mechanisms of the post-aggressive reaction operative, as observed in performance of hemosorption.
