A state of the kallikrein-kinin system, activity of proteolysis inhibitors were studied simultaneously with the functional activity of neutrophils and content of lysozyme in blood serum of 21 patients with chronic kidney insufficiency. Two types of alterations in the kallikrein-kinin system were found in 13 patients maintained on hemodialysis: in four patients content of kallikrein was increased 8-fold as compared with normal level with a decrease in content of prekallikrein, while in nine patients activity of kallikrein was similar to control values but content of prekallikrein was still further decreased. Content of alpha 1-proteinase inhibitor (PI) was distinctly decreased (2-2.5-fold) in these patients, however, the decrease of the inhibitor was not observed in four patients; activity of alpha 2-macroglobulin tended to decrease. The ratio of active neutrophils and content of lysozyme were increased in blood serum of the majority of the patients. Hemodialysis, activation of the kallikrein-kinin system and stimulation of neutrophils appear to be responsible for a decrease in PI activity. The decrease in the PI activity and stimulation of the kallikrein-kinin system suggest that impairments in regulation of proteolysis could be corrected by means of exogenous proteinase inhibitors. In crisis of allogenic kidney rejection activities of PI and prekallikrein were decreased. Drastic, uneven alterations of the patterns studied were detected in pyo-inflammatory complications not related to the rejection crisis.
