title: Thrombopoietin level in patients with chronic liver diseases.
abstract: Thrombocytopenia and oxidative stress are the most frequent problems in patients with chronic liver diseases as viral cirrhosis and schistosomiasis. So, this study aimed to evaluate the role of thrombopoietin (TPO) on the occurrence of thrombocytopenia and in differentiation between these diseases. It also aimed to investigate the relation between TPO, oxidative stress and antioxidant status in these two types of chronic liver disease. So, We measured serum TPO level, lipid peroxide (MDA) and serum total antioxidant activity (TAO) in 40 patients with cirrhosis caused by hepatitis C virus and 37 patients with schistosomiasis from The Specialized Medical Hospital, Mansoura University.
  
  
  RESULTS
  Both serum TPO level and serum TAO activity were significantly lower (p < 0.05) in thrombocytopenic patients with viral cirrhosis when compared to both non thrombocytopenic and control groups. In contrast, TPO level was within the normal range in the patients with scistosomiasis either thrombocytopenic or not. while serum TAO activity was significantly lower (p < 0.05) in both thrombocytopenic and non thrombocytopenic patients with schistosomiasis in comparison to control subjects with no significant difference between these two subgroups. Serum MDA concentration was increased significantly (p < 0.05) in all diseased groups when compared to controls with significant increase in thrombocytopenic patients as compared to non thrombocytopenic.
  
  
  CONCLUSIONS
  TPO hypoproduction played a role in the pathogenesis and treatment of viral cirrhosis associated with thrombocytopenia. Also, total antioxidant activity and MDA are useful markers for monitoring patients with these chronic liver diseases.
