Answer

Although acute hepatitis C virus (HCV) infection is usually mild, chronic hepatitis results in at least 75% of patients. [13] While liver enzyme levels may be in the reference range, the presence of persistent HCV-RNA levels discloses chronic infection. Biopsy samples of the liver also reveal chronic liver disease in patients. Cirrhosis develops in 20-50% of patients with chronic hepatitis C infection. Liver failure and hepatocellular carcinoma can eventually result. Hepatocellular carcinoma occurred in 11-19% of patients. The risk of cirrhosis and hepatocellular carcinoma doubles in patients who have undergone transfusion. [35]

Two studies of compensated cirrhosis in the United States and Europe showed that decompensation occurred in 20% of patients and that hepatocellular carcinoma occurred in approximately 10% of patients. [36, 37] The survival rate at 5 and 10 years was 89% and 79%, respectively. The onset of chronic hepatitis C infection early in life often leads to less serious consequences. [38, 39] Hepatitis B virus (HBV) infection, iron overload, and alpha 1-antitrypsin deficiency may play a role in the progression of chronic hepatitis C infection to HCV-related cirrhosis. [40, 41]

Chronic hepatitis C infection and its major sequelae (cirrhosis and hepatoma) are responsible for 8,000-10,000 deaths a year.
