Treatment of acute hepatitis C: the success of monotherapy with (pegylated) interferon alpha.

Early control in the acute phase of hepatitis C infection is an attractive therapeutic goal in order to shorten disease duration and infectivity, to prevent chronicity and progression to advanced liver disease and to avoid eventual therapeutic non-response in the later stages of chronic hepatitis C. Over the past decade, different interferon-based treatment options have been developed, which lead to sustained virological response rates of up to 98%. The present article summarizes the successful invention of immediate and delayed strategies in acute hepatitis C monoinfection, critically discusses potential limitations and illustrates the therapeutic challenges of the near future.
