001), mean blood pressure from 97.5 ± 11.6 to 87.9 ± 10.1 mm Hg (p = 0.001). There were no significant correlations

between HVPG change and decrease in the heart rate (p = 0.87) or decrease in mean blood pressure (p = 0.38). Non-signifficant adverse reactions were observed in 13 patients (19%), dose reduction was necessary in 4 patients. No serious adverse event was observed. Conclusion: Carvedilol AG-014699 manufacturer is an effective and safe medicament in the treatment of portal hypertension. The response rate is 49%, which is higher than response rate expected in the patients treated with propranol. Supported by IGA MZCR NT 12290/4 and IGA MZCR NT 11247/4.

inappropriate activation of lymphocytes and macrophages. Guidelines for the diagnosis of HLH require the presence of 5 out of 8 findings of fever, splenomegaly, cytopenia, hypertriglyceridemia or hypofibrinogenemia, hemophagocytosis in bone marrow, spleen or lymph nodes, low or absent natural killer cell activity, and elevated serum ferritin and soluble CD25. The full clinical picture of HLH is quite characteristic, but the initial presentation is non-specific and misleading. Liver involvement is not a diagnostic criterion for HLH, but as we have observed, patients with HLH almost always have evidence of liver inflammation. Methods: A previously healthy 49-year-old man was admitted to hepatology department with confusion of the past 2-week history of fever and liver dysfunction. As the disease not progressed, findings of hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and hematophages

in bone marrow appeared gradually. Results: And finally the case met all 8 diagnostic criteria of HLH-2004. Prednisone was used as the basic therapy for him, and his condition was improved remarkably after 16-day hospitalization. Conclusion: HLH is a hematologic disease, but not all HLH patients come to hematologic department at the beginning of the progress. As HLH is a complex syndrome which infects many other systems, doctors of other specialty should also be aware of the syndrome. Key Word(s): 1.
