In addition, 60.7% of the patients enrolled received rituximab-based chemotherapy, which has been demonstrated as able to increase the HCV replication in anti-HCV–positive patients.7 In conclusion, neither occult HCV infection nor its reactivation under strong immunosuppressive chemotherapy were found in the present study in oncohematological patients who were anti-HCV- and HCV RNA–negative. Our data and those of others6, 8 suggest the nonexistence of occult HCV infection.

“Platelets contain not only hemostatic factors but also many growth factors that play important roles in wound healing and tissue repair. Platelets have already been used

for the promotion of tissue regeneration in the clinical setting, such as dental implantation and plastic surgery. Thrombocytopenia, which is frequently found in patients with chronic liver disease and cirrhosis, is due to various causes such as decreased thrombopoietin production and accelerated platelet destruction caused by hypersplenism. However, the relationship between thrombocytopenia and hepatic pathogenesis GSK1120212 molecular weight and the role of platelets in chronic liver disease are poorly understood. In acute liver injury, it is reported that platelets are recruited to the liver and contribute medchemexpress to liver damage by promoting the induction of chemotactic factors and the accumulation

of leukocytes in the liver, whereas platelets or mediators released by platelets can have a protective effect against liver injury. In this review, we highlight the recent accumulated knowledge concerning the role of platelets in chronic liver disease and acute liver injury. Chronic liver disease (CLD), which results in liver cirrhosis and an increased risk of carcinogenesis, is a major cause of mortality and morbidity in many countries.[1, 2] Liver fibrosis represents the consequences of a sustained wound healing response to chronic liver injury induced by a variety of causes including viral infection, alcohol abuse, autoimmune disorders, drug use, cholestasis, and metabolic diseases.[3, 4] Currently, liver transplantation is the only curative approach for end-stage liver cirrhosis, but this process is associated with serious problems, such as graft shortage in living-donor liver transplantation, surgical complications, organ rejection, and high cost.
