Abstract
We are concerned with the investigation of dynamics of the plasma kallikrein-kinin system, elastase-like activity and some serpins, α1-protease inhibitor, α2-macroglobulin and antithrombin III, in patients suffering from general peritonitis and chronic renal failure. The results indicate that activation of the kallikrein-kinin system, as well as elastase-like activity are elevated and while decreased inhibitory potential becomes more intensive with disease progression. However, sharply decreased levels of kallikrein, prekallikrein and the serpins were seen in patients a few days before death. We suggest that exhaustion of these components during the end-stage of general peritonitis and chronic renal failure (in the cases with lethal outcome) may be produced by leukocyte elastase release. Evidence is presented for the destructive action of leukocyte elastase on components of the kallikrein-kinin system.
