In addition, 201 patients with a low INR (http://www.selleckchem.com/products/carfilzomib-pr-171.html (34.2% with tifacogin vs 33.9% with placebo, P = 0.88). Tifacogin administration was associated with an increase in risk of bleeding, irrespective of baseline INR[50,51]. The most common site of infection in this study was community acquired pneumonia. A post hoc analysis suggested patients, who did not receive concomitant heparin, appeared to benefit from treatment with tifacogin. This led to a large phase 3 trial of rTFPI in patients with severe sepsis from community acquired pneumonia[53]. Again, rTFPI treated patients demonstrated a greater reduction in markers of thrombin activity, but no improvement in mortality was noted. CONCLUSION Inflammation and coagulation are tightly linked with each pathway capable of initiating and amplifying the activity of the other. Full blown expression of the coagulation pathway in the septic patient leads to overt DIC, overt but some degree of coagulation activation is apparent in virtually all patients with severe sepsis. Increasing coagulopathy is YES1 associated with the development of organ failures and increased mortality[53]. Simultaneous with the development of the coagulopathy there is a fall in the levels of endogenous anticoagulants including APC, AT, and TFPI as a consequence of both increased consumption and impaired production. Survivors of severe sepsis have more rapid return of this endogenous anticoagulant to normal levels. Because these endogenous anticoagulants appear to have anti-inflammatory activity independent of their ability to inhibit thrombin generation, they were administered to patients with severe sepsis in an attempt to improve outcomes. One trial of rhAPC showed an improvement in the survival of the sickest patients, but this benefit could not be replicated in subsequent studies. Phase 3 studies of AT and TFPI failed to demonstrate a clear benefit while a Phase 3 trial of TM is still in progress. Anticoagulant therapy in a patient with an underlying coagulopathy increases the risk of bleeding, which may obscure any potential benefit. At this time AZD9291 future trials of anticoagulant therapy for sepsis should focus on the most severely ill patients with the highest expected mortality, as this is the group in which benefit is most likely to be demonstrated. Until they can be shown to reduce morbidity and mortality, anticoagulants should not be used for the treatment of severe sepsis.
