Frequency and hemostatic abnormalities in pre-DIC patients.

Disseminated intravascular coagulation (DIC) sometimes has a poor outcome, and therefore early diagnosis and treatment are required. This study prospectively evaluated the hemostatic abnormalities and the onset of DIC in 613 patients with underlying diseases to identify a useful marker for diagnosing Pre-DIC. Pre-DIC was defined as the condition of patients within a week before the onset of DIC. Initially, 34.4% of patients were diagnosed with DIC, and about 8.5% of the patients without DIC were diagnosed as DIC within a week after registration (pre-DIC). The mortality of DIC, Pre-DIC and "without DIC" was 35.3%, 32.4% and 17.2%, respectively. All hemostatic parameters were significantly worse in "DIC" than "without DIC" and the values of the prothrombin time ratio, platelet count and fibrin monomer complex could classify the three groups; "DIC", "pre-DIC" and "without DIC". No useful marker was identified that provided an adequate cutoff value to differentiate "pre-DIC" from "without DIC". A multivariate analysis identified clinical symptoms that were related to poor outcome. DIC must be treated immediately; there is no specific marker to identify pre-DIC.
