Dynamics of kallikreinogen under hemodialysis.
There are many complications due to hemodialysis, causes of which seem to lie under disorders of the coagulation system, fibrinolytic system, and kinin system. Therefore, it is important to understand the dynamics of these systems during hemodialysis. Accordingly, kallikreinogen, plasminogen, plasmin inhibitors, contact factor, antithrombin, and prothrombin were assayed during the experimental dialysis, experimental ultrafiltration and clinical hemodialysis. Plasmin inhibitors decreased remarkably by dialysis. They then recovered the pre-dialytic values as time went on. Kallikreinogen did not show any definite tendency immediately after the beginning of dialysis, but two hours later its value rather increased relative to thepre-dialytic value. It was supposed that this increase was caused by reactive hyperproduction due to gradual consumption of kallikreinogen. Contact factor slightly decreased by dialysis, whereas prothrombin and antithrombin decreased apparently. When hemodialysis is practiced, it is necessary to fully realize that the coagulation system, fibrinolytic system, and kinin system might lose their balance.
