  • Title: The coagulopathy of chronic liver disease: is there a causal relationship with bleeding? Yes.
    Author: Basili S, Raparelli V, Violi F.
    Journal: Eur J Intern Med; 2010 Apr; 21(2):62-4. PubMed ID: 20206871.
    Abstract:
    Variceal hemorrhage is a major cause of death in patients with cirrhosis. Much still could be performed in clinical practice to reduce the risk for bleeding in cirrhotic patients and accurate predictive rules should be provided for early recognition of high-risk patients. Liver cirrhosis patients present a complex hemostatic dysfunction with prolongation of bleeding time, chronic coagulation activation, and secondary hyperfibrinolysis. Therefore, liver failure determines an acquired coagulopathy that has been considered to be one potential underlying mechanism of bleeding. Endotoxemia may play a pivotal role in activating clotting system in portal and systemic circulation and it could represent a common mechanism accounting for portal vein thrombosis, systemic hyperfibrinolysis and eventually gastrointestinal bleeding. Nevertheless, clinical trials should also be planned to investigate the causal relationship between acquired coagulopathy and bleeding in patients with chronic liver disease.
