Abstract
The rate of chronic evolution in patients with acute hepatitis C is 50–90%. Chronicity is associated with the risk to develop hepatic decompensation and hepatocellular carcinoma. Fortunately, it has been shown that the initiation of interferon monotherapy during acute phase of hepatitis C virus infection significantly reduces evolution to chronic hepatitis. Immediate treatment of acute HCV infection within 2–3 months after infection led to 98% of sustained virological response in the pivotal trial using recombinant IFN-alfa-2b and to sustained virological response rates between 84 and 89% using PEG-IFN-alfa-2b for 6 months in subsequent trials. The results of the major trials showed that there is no need for a combination with ribavirin.
Early immediate treatment with PEG-IFNa-2b is highly effective in both symptomatic and asymptomatic patients. Delayed IFNa + ribavirin treatment resulted in lower overall response rates; however, if adherence can be assured this strategy seems to be of similar efficacy in symptomatic patients. The main aim in the management of acute hepatitis C is to find a balance between unnecessary overtreatment of patients who might clear the infection spontaneously and on the other hand to avoid chronicity of hepatitis C infection. In addition, the optimal management of patients with acute hepatitis C infection should include a careful workup of clinical and virological data as well as the consideration of the individual patient’s history.
