Summary
The HCV, a single stranded RNA virus belonging to the family of flavivirus, has been identified as the probable cause of the majority of cases of transfusion-associated NANB hepatitis and community-acquired NANB hepatitis in Japan. The hepatitis virus is present in a least 2% of the blood donor population and is extremely common in high risk groups, such as hemophiliacs and hemodialysis patients. The contribution of HCV infection to sporadic, acute and chronic hepatitis, liver cirrhosis and primary liver cancer has been established. Furthermore anti-HCV in 20% of alcoholic patients with liver injury suggest that HCV may be etiologically associated with liver disease previously attributed to other causes. Therapy of acute and chronic liver disease associated with HCV infection is likely to be undertaken with recombinant IFN alpha in the future to prevent the progression of the disease from acute hepatitis to chronic hepatitis, and from chronic hepatitis to liver cirrhosis or primary liver cancer. However the prevention of HCV infection will be the goal, in addition to screening of donor blood and exclusion to a large degree of positive units likely to decrease the incidence of post-transfusion hepatitis.
