Abstract | BACKGROUND: METHODS: Our prospective pilot study included 22 patients with severe sepsis, nine (41%) of whom had overt DIC. We analysed MMP-8 and TIMP-1 serum concentrations by time-resolved immunofluorometric and enzyme-linked immunosorbent assays, respectively, on days 1, 2, 4 and 7 after the intensive care unit admission. Traditional coagulation tests were taken at the same time points. The results were compared between patients with and without DIC. Blood samples from 10 healthy volunteers were used to demonstrate normal levels. RESULTS: Both patient groups had elevated levels of MMP-8 and TIMP-1 as compared with healthy controls. TIMP-1 concentration was almost twofold in DIC patients compared with those without DIC on the first 2 days. MMP-8 was elevated only on day 2. TIMP-1 correlated positively with the severity of coagulation disturbance and with disease severity scores. MMP-8 correlated negatively only with platelet count. CONCLUSION: In this first human study, we could show that TIMP-1 is elevated in the early phase of sepsis-induced overt DIC, and it correlates both with degree of coagulopathy and disease severity. These findings suggest that TIMP-1 may play a role in the pathogenesis of DIC in septic patients.
