Abstract
  • Cardiopulmonary bypass induces a systemic inflammatory response (SIR), characterized by the activation of cellular and humoral elements, with concomitant release of neutrophil elastase and matrix-metallo proteinases. In the present study, the protease release during extracorporeal circulation in 28 patients undergoing cardiac surgical operations was monitored using casein zymography. A peak in protease activity was found in all patients at the end of cardiopulmonary bypass. Plasma samples of patients were allowed to interact with different traps obtained by immobilizing different protease inhibitors on specific carriers. ±1-Antitpypsin, Bovine Pancreatic Trypsin Inhibitor, Elastatinal or Leupeptin were used as inhibitors and were covalently immobilized by diazotization or by condensation. A reduction in the proteolytic activity of the plasma samples was observed after interaction with the different traps. The most efficient traps, i.e. the ones displaying greatest power to inhibit protease activity, were those obtained by immobilizing Bovine Pancreatic Trypsin Inhibitor and Leupeptin. The biocompatibility of traps was also tested. Results show that protease activity in blood can be decreased by our protease traps. (literal)
