Background:Bleeding is an important complication of cirrhosis. Currently, there is no coagulation test that can reliably predict clinical hemorrhage. However, previous studies demonstrated significant correlations between hyperfibrinolysis and following bleeding in advanced cirrhotic patients. Objectives: Estimate the prevalence of hyperfibrinolysis in cirrhotic patients at stable conditions and to assess its role in predicting subsequent hemorrhage. Methods: The prospective cohort study included 58 consecutive cirrhotic patients at the Liver Clinic, Chulalongkorn Hospital. Assays for liver functions, PT, APTT, fibrinogen, fibrin degradation products (FDPs) and euglobulin lysis time (ELT) were performed at baseline. The subjects were followed-up for 10 months to observe clinical hemorrhage and survival. Results: The mean age was 56.4 years and 47% were male. The etiologies of liver diseases were virus (62.1%), alcohol (24.1%) or unknown (8.6%). Hyperfibrinolysis as reflected by ELT<120 minutes or FDPs>10 μg/mL was present in 32.8% and 74.1%, respectively. Fibrinolytic activity was significantly correlated with platelet counts and coagulation times, but not as much with liver function tests. By 10 months, 13 cases (22.4%) showed hemorrhagic episodes and 7 (12.1%) were expired, including 2 from bleeding. The significant predictors for death were Child class B or C, presence of ascites, hyperbilirubinemia, hypoalbuminemia, and prolonged APTT. However, none of the clinical, biochemical, or hemostatic factors was associated with clinical bleeding. Conclusion: Hyperfibrinolysis is common in cirrhotic outpatients. However, it cannot predict subsequent hemorrhage or survival. Novel hemostatic tests are required to assess the probability of bleeding in this disorder.

Background: Management of unfit AML patients is a therapeutic challenge. Most hematologists tend to avoid aggressive treatment leaving patients with a choice of best supportive care. We hypothesized that metronomic chemotherapy could be an alternative treatment for unfit AML patients. Methods: A multi-center randomized controlled trial was conducted in seven university-affiliated hospitals in Thailand. Unfit AML patients were recruited and followed up from December 2014 to December 2017. Patients were randomly assigned to receive either metronomic chemotherapy or palliative hydroxyurea. Overall survival rates were compared using Cox's proportional hazard survival analysis. Results: A total of 81 eligible patients were randomly allocated and included for ITT analysis. The OS rate was higher in group receiving metronomic chemotherapy than in group receiving palliative treatment at 6 and 12 months with borderline significance (6 months HR 0.60; 95%CI 0.36, 1.02; p-value 0.060; 12 months: HR 0.66; 95%CI 0.41, 1.08; p-value 0.097). Conclusion: Metronomic chemotherapy could prolong survival time of unfit AML patients, especially in the first 12 months after diagnosis without increasing treatment-associated adverse events.
