AbstractIn a search for new variables, for the diagnosis of disseminated intravascular coagulation (DIC) and for guidelines of therapy in such conditions, 22 severely ill patients were studied. The diagnosis of DIC was based on determinations of platelet counts, prothrombin complex (Normotest), antithrombin (AT), fibrinogen degradation products and fibrinogen. Nine patients were diagnosed as having DIC, eight patients were referred to a suspected DIC group and five to a group of no DIC. The laboratory findings were found to agree with the clinical status. In addition several new parameters were investigated: factor XII, prekallikrein, Simplastin A--another prothrombin complex factor method, factor X, plasminogen (PLG), antiplasmin (AP) and kallikrein inhibitors (KI). Platelet counts, prothrombin complex and antithrombin were mostly pathological in DIC-patients. Of the alternative tests prothrombin complex, fibrinopeptide A and the kallikrein inhibitor as well as the two tests for fibrinolysis (PLG and AP) were significantly altered in DIC-patients. The inhibitor capacity (AT, APV and KI) was lower in patients who died than in survivors and decreased still further in those of the non-survivors who had DIC. Thus the inhibitors can be used as predictors of outcome and hopefully for guiding therapy. To establish the diagnosis of DIC we suggest measurement of platelet count, prothrombin complex, plasminogen as well as of the inhibitors.
