Abstract
The coagulation and fibrinolytic systems were analysed parallel to the clinical evaluation in 27 attacks of acute human pancreatitis of different severity. Consumptive coagulopathy was evident from decreased platelet counts, decreased prothrombin values and consumption of fibrinogen during the first days in severe attacks. Fibrinolysis was suggested by decreased plasminogen values and the presence of fibrinogen degradation products. All main protease inhibitors of the two systems showed protease-antiprotease complexation and lower functional than quantitative values. Functional levels of the protease inhibitors were almost zero in the peritoneal fluid in severe attacks. It is concluded that severe acute pancreatitis results in consumptive coagulopathy and fibrinolysis together with a local antiprotease deficiency. All the changes are closely correlated to the severity of the disease.
